One suggestion for anyone salvaging screens: save they laptop lid/case that the lcd is in. That can then serve as a nice case for the monitor you are making. Otherwise making a case can be a pain I've mounted the controller in a plastic project box epoxied to the back or in a larger box that served as the base. Detach the hinges that mount the lid to the main body of the laptop and us them to attach to the base. When I attach the controller to the back of the lid (now monitor case) I make the base out of aluminum stock from the hardware store.
I had a Toshiba Satellite that was about 12 years old and I gutted the case except for the screen and my Pi400 fits in fine along with the lcd board and it works great. There is room to add a hard drive in the case too. I think I just invented the Toshiba/Pi laptop. LOL
Times sure have changed. About 15 years ago I built my own hi def lcd projector. I bought a concept board out of China (had to fib a little and tell them I was doing prototype work to get them to sell me the video card and various cables for use with a few screens I had). The video card was pcie and wildly expensive 😬 cables were custom made for each screen. I had to supply schematics for each screen.. the cables were really cheap. Great video, nice to see people still like to repurpose instead of simply purchasing "box solutions"!
Bought one from a Chinese supplier several years ago. Postal service here in Greece is FUBAR and they almost sent it back. Lucky I contacted the ebay seller and they almost within the hour sent me the tracking info which allowed me to get my package. It came pre configured for my display out of a Toshiba laptop. Only other issue was that it was still programmed for the Chinese language pack. Had to do a calligraphy search for "language" found the info and changed it. Works great! Also has an analog tuner for the EU channels. Built a nice housing out of wood, looks really nice!
Finally! I asked about using old laptop screens years ago. Glad to see someone finally made a board for this. With a fast enough chip, you can make a pretty fair laptop out of what was going to the landfill. Thanks.
These boars exist for years on asian market places. Search for screen driver board and you get loads of them up. I ordered one myself for an old screen for not that much Money and it works. It's not magic, I mean most Monitors and TVs have similar Technology in them.
@@fie1329 For some reason, I never knew this. I asked a few times because I have a few displays and wanted to make use of them. The only option I found was buying the driver card on eBay. I wonder if you can use device screens like iPodTouch and old Android phones. They're cheap and have all kinds of parts in them.
Connected my raspberry pi Hdmi to controller board hdmi which is connected to my laptop screen. The brightness is very low, hardly can make out anything.. is there any option to increase the brightness or is it a backlight issue?
I had a dead 40" LCD TV given to me by someone who didn't want to pay cost of main power board. Hooked up video on life support, but that had screwy voltage requirements and ran hot. Then found great LVDS controller at Digital View and ordered it off DigiKey. Short end, after remapping all JAE pins and setting jumpers, this deshelled LCD make a very nice monitor.
This video is fantastic and was just what I was looking for. Thank you so much for taking the time to make it. I want to try and strip out an old HP Jornada 680 handheld and fit a Pi inside trying to utilise the screen. Many thanks again!
I bought myself a vintage lunchbox case, but didn't get the video card for it, so it sits in my closet. I've been thinking of trying to get a 10.4" lcd and one of these boards to replace its display, and then put a vintage system inside for semi-portable vintage computing... (it's current display is some 50 pin kind of thing that requires a Chips & Technology video card.)
10:15 that is for led backlight some lcd panels have led backlight using those connectors ! ... ccfl type backlight needs much more cricut and a big high voltage transformer ...
I would think it will drive either as the LDC panels typically have a 5-20V input for the LED BL, and it boosts it up to 28-32V. the CFL booster of course can go up to close to 1000V, but both are initially supplied with similar low starting volts. I was not intending to say that the controller actually generated the HV for the CFL
Nice video! Very informative. Though one correction: the N156BGE-L21 panel at 8:14 is 1366*768, not 1024*768, this can be easily seen simply by the dimensions of the panel. I've never seen a 4:3 aspect ratio 15.6" panel by the way. 15.4 are usually 16x10 and all the 15.6" ones I've come across are 16x9. If it operated at 1024*768 that is usually a sign of missing graphics drivers on the device it was connected to. I myself came to this video in search of a converter board from lvds to 2 or 4 channel mipi, which would allow a direct connection to mipi dsi interface of SBC's like the rpi4, but no luck so far!
This has been possible for many years. Simply by getting the control board for the monitor ($30 ish) , making a frame for the screen and connecting the RPI via hdmi. Excellent tutorial though!
Jay controllers are specific to the panel, each will have model specific number on the back of the panel. A quick entry into amazon or eBay (amazon preferred) such as “”model number” driver board” there will be various options for io which is simple preference for what you need/want
GREAT Video! I have a question!?? The link in the description doesn’t work, can you update me with the link to the board? Or the name of the board or one similar?
Have you poked around with a multimeter yet? Or even better, have a schematic? It would be amazing if you could draw power to run the Pi directly from the board so you only need a single power supply for both!
I always thought that given how beefy old laptops were, Raspberry Pi should do its bestest to help users recycle their old laptops. All you need should be an R-Pi, intermediate board for all I/O (screen, keyb, trackpad, CD-ROM, HDD, USB, LAN...), lots of wires & solder and glue. The old useless laptop mobo obviously goes to a drawer labelled "for parts."
LOVED this video. I have been wanting to get into doing this for years. I do feel I need to point out that the screen you said was 1024 x 768 is definitely higher res. Easy to tell it wasn't going to be that res considering it's a wide screen. 1024 x 768 is a 4:3 aspect ratio and widescreen monitors are 16:9, 16:10, 21:9 etc. etc. If it indeed only supported a 1024 x 768 resolution, there's no way it would show anything on the screen at higher resolutions. It would be WAY out of range and either give you a seizure inducing flicker, or more likely just go black. If you check the resolution on the Pi, it should say what recommended is like windows does.
You are correct, After the video I found the proper reference to it and indeed it is like the rest, WXGA 1366x768, I think this is what the PC / PI initially returned to me on their settings. and I forgot to go back and correct it in the post editing, the site www.panelook.com is excelent at getting the details for most panels. and now my goto for details
@@TheBreadboardca Connected my raspberry pi Hdmi to controller board hdmi which is connected to my laptop screen. The brightness is very low, hardly can make out anything.. is there any option to increase the brightness or is it a backlight issue?
I want to build an all in one sorta thing, like i have a Laptop Display, a Raspberry pi 4 and hard drive, maybe like 3d print a Enclosure and design it around the screen and everything idk how to start other than get a Controller board for the screen
Do you have a page wherein you explain these things written down perhaps? This actually is really interesting & helpful. I would like more detailed information about these things. Thanks for the effort of sharing!!
Hi thanks for the informative detail on the reuse of display. I have a old sony vaio vgn fe11m model which has stopped working but display is very good. Can you please recommend a display connector for it. Thanks a many Ravi
Will totally work with the video output from a drone receiver, took an old laptop screen and a pelican case with a 3s 5000mAh battery, 12v regulator, 5v regular and fed the LCD controller with the 12v and video receiver with 5v, 3d printed a dock-king style enclosure with the video feed soldered into an RCA connector and voila you've got a portable FPV feed viewer screen to show your friends the wonder of FPV drones
That board seems to be unavailable now. Should we go looking for a LVDS to HDMI converter or is there more to it than that? Any suggestions on another board that's currently available? I'm interested in replacing the guts of my MacBook Pro 17" with a Raspberry Pi. Thanks for sharing this video.
One question, I dont know if my display is working and the laptop i pulled it out of wasn't working. So how do i test the display without wasting 25-30 bucks on a controller board? I dont have more displays to use it on.
theBreadboard I’ve done this successfully. You get a really sharp image and it works from the second the Pi boots. The only downsides are that it takes some configuration to get the display mode line correct and it can consume a lot of the GPIO pins.
Inspirational video, thanks for uploading. I wonder if it is possible to use it with old TV-LCD-display-panels. Probably not suitable to power the backlit bulbs but maybe there is a way to replace the bulbs with LEDs. Could be a good source. Those panels are also LVDS but with a larger connector. Any thoughts on this?
Actually, alot of none 4K screens are still able to be driven by these boards, the issues is if they have CCFD's which would require a separate driver, if LED then I think if you provide the right VED voltage/current it could still well work. the important bit is they still often use one of those LVDS connectors.
Just tried it for my raspberry pi 4 and it works, now what do you recommend to make it fully portable, like what batteries or power bank I could use for that
If you have good replacement screen that otherwise mechanically fits except for the connector placement; Perhaps you could source a small extension or even just a longer twisted-pair replacement not too unlike the one that came with your device. Granted, I'm not sure what kind of tolerances the differential signaling could tolerate, I presume a few (cm) wouldn't be a problem provided all pairs were extended the same distance. Though in many cases I don't know if even this would be worth it, but perhaps interesting to try.
I'm hoping their other board listed "B156XW02 LCD Controller Board HD DVI VGA Audio PC Module Kit For 1366x768" is the new version as the link is out of date (I cant seem to post links). Hoping it will work with my Acer ASPIRE 5745-7247 screen, it's 40 pin and 1366 * 768, I couldn't figure out more specs though.

So if you have an old laptop you could take out the mother board, and if enough space insert a raspberry Pi and screen controller board and you have a new machine.
i have 2 old laptop display yesteday just take out of broken computer cases. but i not know what controller thats need use,not have same 40 pin flat cable connection, have out jst style connection plug. acer have model B173RW01 lcd moduleLK 17305001938F84582000 how i know what controlelr i muyst orden ? i have one controller new 10 inch display board think made raspi 10" display but have broken display, controlelr have new only used test and see all picture have broken.
The cables are available via the links I provided, just link into them and then search for something like " 2 ch, 6 bit LVDS cable 30 pin" and something should present itself. As far as the display goes, dell does not actually make the LCD panels but the model number etc on the panel will tell you who did, and to answer your question re the panel, yes it should work, if it is a 1366 x 768 resolution, look at the 3rd video in the series ruclips.net/video/mHVrsOhccdM/видео.html for more details on finding the controller for you.
It could be that the part number is lasered off to either: 1) avoid IP infringement, 2) hide origin of product, 3) because it might be a conferfeit board.
Great video and the topic but I’m missing details about the signalling/protocol. Also if the chip is scaling the input to the panel, is it feeding back the native resolution to the source making it possible to select? I tried different resolutions panels with the TTL output but could not find details on how to adjust the resolution. The TTL being “dumb” it has to be done in the chip itself I believe. Anyway, thanks for this one. I’m interested more in LVDS than TTL.
Did you get to watch the LVDS video, did it help ? ruclips.net/video/Gph9hYLPMFk/видео.html, the panel will scale but once configured it will also work and report native resolution
if you want the audio out from the control board, then yes, I would suggest a different board, the one I show in my followup video would be a good example, and is fully programmable for many different resolutions, and has a TV tuner (Analog) and can play media files from a USB key, see ruclips.net/video/mHVrsOhccdM/видео.html
Very informative video, thanks. I am trying to hookup a usb microscope to a display like this, but don't know any controller board that has a usb video input. Any suggestion will be very helpful.
I have not seen any USB video input video controllers yet, HDMI/other to USB sure, but not USB Video to display, and the only USB I know of off hand right now that supports true video over usb is USB 3 GEN 2
Nice! I have a really old Thinkpad (think IBM Thinkpad circa 2000). The panel is a LP133X7 F21B and I'm finding very little info on it. Finding other LP133X7 panels but not the F21B. Anyone know if this will work?
other then attaching the HDMI cable to the pi, nothing else is connected. This is basically the control board of a PC monitor. There are some boards that allow for a few fancy features that you might attach to GPIO pins, though.
Yes it is, maybe not in the first few lines, but it is there Here it is again just to be sure you have it the board I bought can be found here:- www.banggood.com/custlink/3DK...
Great video, I could watch these all day. I have an old Toshiba SATELLITE C655-S5307 with this screen LED-1366-768-G-40-15.6-A116 and I want to use the screen as a stand alone display for my Raspberry Pi400. and I need a control board/ pcb board/Control board (I'm not sure of the right term) The resolution is1366x768 and it has a 40 pin video connector. Where can I find one? To be compatible with the screen does it just need to be the same resolution and pin/plug type. Thanks, Mike
You should be teaching classes to make responsible and individual youths to do such part tome work that can earn them some tax free income. You are awesome sir.
Wow. So does this mean that pretty much any laptop screen of a standard size uses the same connector pinout? So all I have to worry about is if it's 2 channel? Also how do you tell if it's one or two channel? This is amazing.
You'll basically find at most 3 different types of screens. Really old laptops use the CFL backlit screens that'll have an extra 2 wires coming out of the screen itself powering the CFL back light. I can't remember the pin count but it's a different connector. The 40pin ones in the video is used in most old-ish to fairly modern laptops, always LED backlit and in use in laptops ranging from core 2 duo age up to some 6th gen i processors. From 5th gen i processors onward most laptops use the 30pin connectors, basically does the same thing but probably a different controller board or maybe just a different cable from the board to panel. So it's the CFL screens (super old), 40pin LED and 30pin LED. As for the channel thing, I guess it's mostly resolution based so higher resolution screens will probably be 2 channel and you can look that up if you google the part number of the panel
I have a board hooked up to the screen from my old toshiba laptop and it works fine but I have to start up the Pi to a tv screen first and then switch it over to the stand alone laptop screen from my old laptop. The screen stays blank and says no signal until I start it up to the tv and then switch it. What do I have to do to just start it up to my old screen? Thanks in advance, Mike
How do you go about decoding the wiring? Ive been building some old prop laptops (see videos) but would love to use the original screens, instead of putting a mitsubishi screen in.
The LVDS lines are pretty standard for these screens, the only real variances for screens upto 1080p is one or two lane LVDS and the voltage, the pinout is pretty standard.
There’s a few hp touchscreen laptops that take a $50 screen with digitizer built in and connect ONLY through a normal 30 (or 40 - I can’t remember) pin laptop lcd connector. I will get models and wonder if they would work. Any ideas? Anyone familiar with these? I’m NOT talking about the ones with a glued on digitizer with its own control board or the ones that sit behind a separate digitizer.
Hi, i have a "chi mei" monitor [N154l3 -L03] taken from a hewlett p. laptop and i'm going to buy this: T.V53.03 Universal LCD LED TV Controller Driver Board TV/PC/VGA/HDMI/USB+7 Key Button+2ch 6bit 30pins LVDS Cable+1 Lamp Inverter, am i correct ? i'm total noob ...
hellooo I have 4 of those board that has everything except the part to connects to the monitor. where can I buy the ribbon cable for laptop screen. all over I have seen you need to match board with screen..
The board that you linked in your description, I see it takes composite video (AV) which obviously means that board supports interlaced signals like 480i. Do interlaced signals work over the HDMI input? could you run 480i over HDMI?
I have a need to run 30 screens, each screen with a different image determined by a single program. I am very noob and wondering how to design this architecture. My guess is that I need 30 separate screens (duh) and 30 display driver boards but instead of running a raspberry pi for each screen I would like to process on 1 machine and distribute. Any tips or ideas on how this needs to work? I can't think of a processor with 30 hdmi outputs. Is there another way to think about this?
the connectors to the screens are LVDS (Im not sure of the official name. I get them ready wired for different screens). In the case of these screens, the power is supplied through that one connector, other screens may have different arrangements. the power to the board is from a standard 12V wall adapter (rated at a few amps or more), you need to ensure that the board is jumpered correctly for the volts needed for your LCD. it could be 3.3V, 5V or 12V even. check the specifications before powering up
I was hoping you'd do a tear-down so we could see what chips were used so we could bypass Banggood and do a DIY... but, alas, the moment you said "The markings have been etched off the chip", it was not to be. :( ........ oh! I should have WATCHED the video, and you'd have told me...... DUH!
When you say transformer, I assume you mean the power brick?, you do need some kind of power supply, there are no micro controllers or SBC's I'm aware of with enough excess power to supply a bigger display and its back light., (Mainly the backlight)
@@TheBreadboardca I was referring to the inverter I think? I see some boards have one with the reset of the equipment. Or should the small pcb on the back of the screen be sufficient?
@@sdmilliken ah, so that depends on the panel you have, if yours is an LED back light then no, if it is a CCFL that's cold cathode fluorescent... then perhaps, if your extracted panel does not include the inverter as a separate unit then yes, some times you can reuse the old ones but I think it may be easier for most to just get the ones that work with the controller, that way when the screen goes off, so does the battery light, hope that helps
Is there an easy way to connect touch-capability to Raspberry PI as well? If so - do you know of any nice 8-bit (PVA?) panels with touch, to build - say - kitchen tablet?
@@davelapp4740 most touch screens that are add on are based on a USB interface so easy to get working. The official PI LCD uses an I2C interface and has a linux driver that supports it, this would be a little more technical to integrate,
I bought the same board here and the controller only works when the LVDS cable is unplugged from the board. Kind of defeats the purpose. Is there also a way to get audio from this board?
Can you let me know the model of LCD display, the link to the board you purchased, and how you know the board works without the display plugged in?, ill try and help. Re the audio, I dont think this board supports it, if you watch my second video I look at some other boards and the one there does support stereo audio and can drive speakers directly ruclips.net/video/mHVrsOhccdM/видео.html
How are you powering the controller board? Will any 12v power supply work?? How many amps do these monitors/control board require? Is there a 24v power supply? Thanks in advance.
You should aim for 2A or more, this depends mostly on how much current the backlight / CFL will draw (The actual screen does not draw much current in relation to the backlights), but a typical 12V 5A supply will take care of most situations, I would be careful of using 24V as the onboard regulators or circuits may not like it and you could fry everything. if the controller does not say it can take 24V then dont. this does not mean you cant use a 24V primary supply and add a buck convertor to bring it down to 12V efficiently,
mine did not work so i also have the controller board same as yours im just missing lvds cable so i bought one online but when it arived i was so eager to try it out then when i pluged it in the screen is like yes it flickered black once but after that its just back light and a dark screen and i dont know why the lvds cable that i have was 100% compatible to my lcd but yah i dont know why i also checked my wirings if they are connected in the right way but i still have nothin
it seems you need to get the board configured for the panel, they all seem to be available, along with the right cable. it is possible to re-program them but I have not figured out that yet. so for now it is easier to just get the one already configured for your panel
based on what i can see of the specifications here www.panelook.com/LTN156AT02-D09_Samsung_15.6_LCM_parameter_22692.html it should work, you will need to set the lvds voltage to 3v3 as indicated in the specifications
I have a Samsung brand LCD from a Lenovo / IBM laptop. How do I identify correct attachment cable to make it work? THAT IS MY ROAD BLOCK. HUMBLE APPRECIATION FOR YOUR GUIDANCE. I CAN SEND PICTURE OF PLUGS AND CURRENT S OFF LCD.
hi, do you have any video tutorial about converting an lcd monitor that uses ccfl to leds? I have a 22" Dell monitor showing no image , turns on then after 5 secs turns off and one of the lamps is visibly burnt but I cant get no replacement for that
you can get sound from the a/v jack on the PI, you may have to adjust the configuration file to enable it., if the adapter you are using for the old laptop screen has an audio output, this would be a better choice, the PI does also output audio over the HDMI by default.
Assuming it's the 21.5 inch at 1080p, it should work, as I've seen quite a few consumer PC monitors using that same panel, including the Dell S2218H and HP 22CWA. So even if you can't find a Chinese no-name board that works with that panel, you may (theoretically) be able to get the control board from a PC monitor that used the same panel model, and theoretically, the same kind of LVDS connection.
I have an old XPS 13 which has a 1920x1080 display. Unfortunately, it seems this controller board is only for 1366x768 even though it'll accept a 1080p input signal. I was excited for a second.
i am looking into other boards and trying to get more displays other than the 1366x768, I just got my other driver boards and am getting to grips with the settings etc.
Funny you should ask that, I am about to try in the next little while with an older LG 42" TV, I have not found any reason why not so far as long as you have the right LVDS cable and a big enough driver for the LED back light
It very much depends on what display your connecting and what kind of back-light it uses, but typically between 2 and 5 amps should work for most scenarios.
One suggestion for anyone salvaging screens: save they laptop lid/case that the lcd is in. That can then serve as a nice case for the monitor you are making. Otherwise making a case can be a pain
I've mounted the controller in a plastic project box epoxied to the back or in a larger box that served as the base.
Detach the hinges that mount the lid to the main body of the laptop and us them to attach to the base. When I attach the controller to the back of the lid (now monitor case) I make the base out of aluminum stock from the hardware store.
Oh! I remember doing that a while back when I did the controller board thing with a broken car GPS unit…
I'm going to try and do this as well.
Sounds like a good idea!

Easy to tell it wasn't going to be that res considering it's a wide screen. 1024 x 768 is a 4:3 aspect ratio and widescreen monitors are 16:9, 16:10, 21:9 etc. etc. If it indeed only supported a 1024 x 768 resolution, there's no way it would show anything on the screen at higher resolutions. It would be WAY out of range and either give you a seizure inducing flicker, or more likely just go black. If you check the resolution on the Pi, it should say what recommended is like windows does.
You are correct, After the video I found the proper reference to it and indeed it is like the rest, WXGA 1366x768, I think this is what the PC / PI initially returned to me on their settings. and I forgot to go back and correct it in the post editing, the site www.panelook.com is excelent at getting the details for most panels. and now my goto for details
@@TheBreadboardca Connected my raspberry pi Hdmi to controller board hdmi which is connected to my laptop screen. The brightness is very low, hardly can make out anything.. is there any option to increase the brightness or is it a backlight issue?
Great to know! Cheap display controller board too! Thanks for posting the video!
I want to build an all in one sorta thing, like i have a Laptop Display, a Raspberry pi 4 and hard drive, maybe like 3d print a Enclosure and design it around the screen and everything idk how to start other than get a Controller board for the screen
Do you have a page wherein you explain these things written down perhaps?
This actually is really interesting & helpful. I would like more detailed information about these things.
Thanks for the effort of sharing!!
Hi thanks for the informative detail on the reuse of display. I have a old sony vaio vgn fe11m model which has stopped working but display is very good. Can you please recommend a display connector for it. Thanks a many Ravi
Will totally work with the video output from a drone receiver, took an old laptop screen and a pelican case with a 3s 5000mAh battery, 12v regulator, 5v regular and fed the LCD controller with the 12v and video receiver with 5v, 3d printed a dock-king style enclosure with the video feed soldered into an RCA connector and voila you've got a portable FPV feed viewer screen to show your friends the wonder of FPV drones
I am literally pulling the parts together to video doing just that... wow !, small world. it should be interesting.
That board seems to be unavailable now. Should we go looking for a LVDS to HDMI converter or is there more to it than that? Any suggestions on another board that's currently available? I'm interested in replacing the guts of my MacBook Pro 17" with a Raspberry Pi. Thanks for sharing this video.
very cool also a great way to fix a monitor that has a bad driver board
Lcd controller board link is broken. Can you post an updated one or give the name of the board please?
One question, I dont know if my display is working and the laptop i pulled it out of wasn't working. So how do i test the display without wasting 25-30 bucks on a controller board? I dont have more displays to use it on.
With the correct Device Tree overlay blob, you can drive Parallel RGB (not LVDS) display’s directly from the GPIO port of a Pi.
yes indeed, I have not tried that yet but it would be interesting to try
theBreadboard I’ve done this successfully. You get a really sharp image and it works from the second the Pi boots. The only downsides are that it takes some configuration to get the display mode line correct and it can consume a lot of the GPIO pins.
You can also go to the channel diy perks and look for the video of a second monitor and he shows u were he found those control boards and everything
I also show were to get them and how to look up the panel to get the right details to match the display :)
@@TheBreadboardca Oh ok thanx
Inspirational video, thanks for uploading. I wonder if it is possible to use it with old TV-LCD-display-panels. Probably not suitable to power the backlit bulbs but maybe there is a way to replace the bulbs with LEDs. Could be a good source. Those panels are also LVDS but with a larger connector. Any thoughts on this?
Actually, alot of none 4K screens are still able to be driven by these boards, the issues is if they have CCFD's which would require a separate driver, if LED then I think if you provide the right VED voltage/current it could still well work. the important bit is they still often use one of those LVDS connectors.
This board have been discontinued, so no way yo buy the same product. Any news on upgrades/replacement? Thanks :)
Just tried it for my raspberry pi 4 and it works, now what do you recommend to make it fully portable, like what batteries or power bank I could use for that
So this means do not throw any electronics away, very fascinating
certainly be choosy which you throw out and dont be afraid to strip it down first and keep the good bits :)
If you have good replacement screen that otherwise mechanically fits except for the connector placement; Perhaps you could source a small extension or even just a longer twisted-pair replacement not too unlike the one that came with your device. Granted, I'm not sure what kind of tolerances the differential signaling could tolerate, I presume a few (cm) wouldn't be a problem provided all pairs were extended the same distance. Though in many cases I don't know if even this would be worth it, but perhaps interesting to try.
I'm hoping their other board listed "B156XW02 LCD Controller Board HD DVI VGA Audio PC Module Kit For 1366x768" is the new version as the link is out of date (I cant seem to post links).
Hoping it will work with my Acer ASPIRE 5745-7247 screen, it's 40 pin and 1366 * 768, I couldn't figure out more specs though.
So if you have an old laptop you could take out the mother board, and if enough space insert a raspberry Pi and screen controller board and you have a new machine.
That's an interesting idea. I wonder if the chassis would have enough space inside for some decent active cooling.
i have 2 old laptop display yesteday just take out of broken computer cases. but i not know what controller thats need use,not have same 40 pin flat cable connection, have out jst style connection plug. acer have model B173RW01 lcd moduleLK 17305001938F84582000 how i know what controlelr i muyst orden ? i have one controller new 10 inch display board think made raspi 10" display but have broken display, controlelr have new only used test and see all picture have broken.
Important stuff. Please make more.
1. Where do you get a 2-channel cable from? 2. Will this controller work with Dell display?
The cables are available via the links I provided, just link into them and then search for something like " 2 ch, 6 bit LVDS cable 30 pin" and something should present itself. As far as the display goes, dell does not actually make the LCD panels but the model number etc on the panel will tell you who did, and to answer your question re the panel, yes it should work, if it is a 1366 x 768 resolution, look at the 3rd video in the series ruclips.net/video/mHVrsOhccdM/видео.html for more details on finding the controller for you.
It could be that the part number is lasered off to either: 1) avoid IP infringement, 2) hide origin of product, 3) because it might be a conferfeit board.
This is going to work perfect to use my Galaxy S8 a little semi-portable computer.
Any suggestions on how to secure the contacts back on the screens better?
all the screens i ripped apart were using captan tape.
Great video and the topic but I’m missing details about the signalling/protocol. Also if the chip is scaling the input to the panel, is it feeding back the native resolution to the source making it possible to select? I tried different resolutions panels with the TTL output but could not find details on how to adjust the resolution. The TTL being “dumb” it has to be done in the chip itself I believe. Anyway, thanks for this one. I’m interested more in LVDS than TTL.
Did you get to watch the LVDS video, did it help ? ruclips.net/video/Gph9hYLPMFk/видео.html, the panel will scale but once configured it will also work and report native resolution
good video was wandering how I would do this now I know spot on
Works a treat .but how would I get sound out..or would I have to buy a different control board with that option.cheers..
if you want the audio out from the control board, then yes, I would suggest a different board, the one I show in my followup video would be a good example, and is fully programmable for many different resolutions, and has a TV tuner (Analog) and can play media files from a USB key, see ruclips.net/video/mHVrsOhccdM/видео.html
Do I have to us the driver board. Can't I use a ribbon cable and connect the LCD to thee dsi port on the raspberry pi
You list prices in Canadian dollars, greetings fellow Canuck! I'm displaced.. living in the Philippines these days
Thanks for all the feedback, glad your enjoying the channel, more will be coming soon
Very informative video, thanks. I am trying to hookup a usb microscope to a display like this, but don't know any controller board that has a usb video input. Any suggestion will be very helpful.
I have not seen any USB video input video controllers yet, HDMI/other to USB sure, but not USB Video to display, and the only USB I know of off hand right now that supports true video over usb is USB 3 GEN 2
Very interesting, but I don't follow how you determine which LCDs work with which boards and or cables.
Nice!
I have a really old Thinkpad (think IBM Thinkpad circa 2000). The panel is a LP133X7 F21B and I'm finding very little info on it. Finding other LP133X7 panels but not the F21B. Anyone know if this will work?
you mean this one :) www.panelook.com/LP133X7-F2IB_LG%20Display_13.3_LCM_overview_5201.html
Wish you would have shown how it was hooked up to the Raspberry pi for us noobs.. I ordered one anyway. Thanks!
other then attaching the HDMI cable to the pi, nothing else is connected. This is basically the control board of a PC monitor. There are some boards that allow for a few fancy features that you might attach to GPIO pins, though.
Hi I cannot find this board you are using. A link is not in your description. Please help. Thanks
Yes it is, maybe not in the first few lines, but it is there
Here it is again just to be sure you have it
the board I bought can be found here:-

Great video, I could watch these all day. I have an old Toshiba SATELLITE C655-S5307 with this screen LED-1366-768-G-40-15.6-A116 and I want to use the screen as a stand alone display for my Raspberry Pi400. and I need a control board/ pcb board/Control board (I'm not sure of the right term) The resolution is1366x768
and it has a 40 pin video connector. Where can I find one? To be compatible with the screen does it just need to be the same resolution and pin/plug type. Thanks, Mike
What would I need to do to connect from the pi to the screen I have a LG LP156WH4
You should be teaching classes to make responsible and individual youths to do such part tome work that can earn them some tax free income. You are awesome sir.
Is there any effect of lowere ampered adapter to the function of the controller? Is lower amper causing not functional LCD sceen?
$20 board plus laptop screen vs a thrift store monitor
which will be more cost effective?
I'm thinking the thrift store
Wow. So does this mean that pretty much any laptop screen of a standard size uses the same connector pinout? So all I have to worry about is if it's 2 channel? Also how do you tell if it's one or two channel? This is amazing.
You'll basically find at most 3 different types of screens. Really old laptops use the CFL backlit screens that'll have an extra 2 wires coming out of the screen itself powering the CFL back light. I can't remember the pin count but it's a different connector. The 40pin ones in the video is used in most old-ish to fairly modern laptops, always LED backlit and in use in laptops ranging from core 2 duo age up to some 6th gen i processors. From 5th gen i processors onward most laptops use the 30pin connectors, basically does the same thing but probably a different controller board or maybe just a different cable from the board to panel.
So it's the CFL screens (super old), 40pin LED and 30pin LED. As for the channel thing, I guess it's mostly resolution based so higher resolution screens will probably be 2 channel and you can look that up if you google the part number of the panel
Bro you have any idea how to connect a smartphone motherboard lcd connector to connect a 15 inch laptop lcd panel with digitalizer.
I have a board hooked up to the screen from my old toshiba laptop and it works fine but I have to start up the Pi to a tv screen first and then switch it over to the stand alone laptop screen from my old laptop. The screen stays blank and says no signal until I start it up to the tv and then switch it. What do I have to do to just start it up to my old screen? Thanks in advance, Mike
How do you go about decoding the wiring? Ive been building some old prop laptops (see videos) but would love to use the original screens, instead of putting a mitsubishi screen in.
The LVDS lines are pretty standard for these screens, the only real variances for screens upto 1080p is one or two lane LVDS and the voltage, the pinout is pretty standard.
You filled in a blank spot for me as I have a hinge on my LT broken but little money to put in it
There’s a few hp touchscreen laptops that take a $50 screen with digitizer built in and connect ONLY through a normal 30 (or 40 - I can’t remember) pin laptop lcd connector. I will get models and wonder if they would work. Any ideas? Anyone familiar with these? I’m NOT talking about the ones with a glued on digitizer with its own control board or the ones that sit behind a separate digitizer.
Hi, i have a "chi mei" monitor [N154l3 -L03] taken from a hewlett p. laptop and i'm going to buy this: T.V53.03 Universal LCD LED TV Controller Driver Board TV/PC/VGA/HDMI/USB+7 Key Button+2ch 6bit 30pins LVDS Cable+1 Lamp Inverter, am i correct ? i'm total noob ...
hellooo I have 4 of those board that has everything except the part to connects to the monitor. where can I buy the ribbon cable for laptop screen.
all over I have seen you need to match board with screen..
you can also get them from Banggood, try this link www.banggood.com/custlink/Gv3vkKuvEt
Using the datasheet from your LCD, you can refine the search to that needed for your display
how do I use the wacom digitizer (su5r12w04au01x ) on my od lapto screen? the laptop "was an hp tx2000, thanks.
Thank you, great video. So for all of the panels the pin map for the 40 pin connector is the same?
The LVDS connector is a standard and most screen manufacturers do keep to that same pinout,
The board that you linked in your description, I see it takes composite video (AV) which obviously means that board supports interlaced signals like 480i. Do interlaced signals work over the HDMI input? could you run 480i over HDMI?
I dont have a 480I signal to test with, sorry. I looked and can not find a reference to this scenario .
One more happy viewer to know that this board existed, could you also share the link for the 2 lane LVDS Kit or the cable as well. Thanks!!
How do you determine weather it is a 2-channel or 4-channel?
I have a need to run 30 screens, each screen with a different image determined by a single program. I am very noob and wondering how to design this architecture. My guess is that I need 30 separate screens (duh) and 30 display driver boards but instead of running a raspberry pi for each screen I would like to process on 1 machine and distribute. Any tips or ideas on how this needs to work? I can't think of a processor with 30 hdmi outputs. Is there another way to think about this?
Please I have a lg LP156WH4 laptop screen and I have a raspberry pi 3 and a lvds but for some reason the screen will turn on but I have no picture
Which gpio to connect for 40 pin display connector
Does the controller run hot? Does it need a heatsink?
Can you set it to use the native resolution of the panel?
Great Video Man !
I am curious if it is possible to use dead mobile's LCD Screen with Raspberry Pi?
Thoughts?
Hell Yes. I have a few laying here in the some day pile. How can you determin if they are single of double ?
new boards are in so now I can show even more
@@TheBreadboardca Price went up 5 dollars following the video. LOL
I'm a bit of a noob with this... what are you using to power the screens? what kind of connector is that? Thanks!!
the connectors to the screens are LVDS (Im not sure of the official name. I get them ready wired for different screens). In the case of these screens, the power is supplied through that one connector, other screens may have different arrangements. the power to the board is from a standard 12V wall adapter (rated at a few amps or more), you need to ensure that the board is jumpered correctly for the volts needed for your LCD. it could be 3.3V, 5V or 12V even. check the specifications before powering up
I was hoping you'd do a tear-down so we could see what chips were used so we could bypass Banggood and do a DIY... but, alas, the moment you said "The markings have been etched off the chip", it was not to be. :(
........ oh! I should have WATCHED the video, and you'd have told me...... DUH!
Glad you found it. have fun
do you need the transformer with these boards, or are the units without the transformer ok to use? I have a lp173wd1. Thanks for your info.
When you say transformer, I assume you mean the power brick?, you do need some kind of power supply, there are no micro controllers or SBC's I'm aware of with enough excess power to supply a bigger display and its back light., (Mainly the backlight)
@@TheBreadboardca I was referring to the inverter I think? I see some boards have one with the reset of the equipment. Or should the small pcb on the back of the screen be sufficient?
@@sdmilliken ah, so that depends on the panel you have, if yours is an LED back light then no, if it is a CCFL that's cold cathode fluorescent... then perhaps, if your extracted panel does not include the inverter as a separate unit then yes, some times you can reuse the old ones but I think it may be easier for most to just get the ones that work with the controller, that way when the screen goes off, so does the battery light, hope that helps
Is there an easy way to connect touch-capability to Raspberry PI as well?
If so - do you know of any nice 8-bit (PVA?) panels with touch, to build - say - kitchen tablet?
Yes you can purchase a USB touch display
If you salvage a screen with touch it might have a usb interface. I have seen at least one laptop touch panel that was usb.
@@davelapp4740 most touch screens that are add on are based on a USB interface so easy to get working. The official PI LCD uses an I2C interface and has a linux driver that supports it, this would be a little more technical to integrate,
@@TheBreadboardca true but I'm talking about actual salvage touch screens from laptops with touch. Those also seem to be (at least sometimes) USB
I bought the same board here and the controller only works when the LVDS cable is unplugged from the board. Kind of defeats the purpose. Is there also a way to get audio from this board?
Can you let me know the model of LCD display, the link to the board you purchased, and how you know the board works without the display plugged in?, ill try and help.
Re the audio, I dont think this board supports it, if you watch my second video I look at some other boards and the one there does support stereo audio and can drive speakers directly
ruclips.net/video/mHVrsOhccdM/видео.html
How are you powering the controller board? Will any 12v power supply work?? How many amps do these monitors/control board require? Is there a 24v power supply?
Thanks in advance.
You should aim for 2A or more, this depends mostly on how much current the backlight / CFL will draw (The actual screen does not draw much current in relation to the backlights), but a typical 12V 5A supply will take care of most situations, I would be careful of using 24V as the onboard regulators or circuits may not like it and you could fry everything. if the controller does not say it can take 24V then dont. this does not mean you cant use a 24V primary supply and add a buck convertor to bring it down to 12V efficiently,
mine did not work so i also have the controller board same as yours im just missing lvds cable so i bought one online but when it arived i was so eager to try it out then when i pluged it in the screen is like yes it flickered black once but after that its just back light and a dark screen and i dont know why the lvds cable that i have was 100% compatible to my lcd but yah i dont know why i also checked my wirings if they are connected in the right way but i still have nothin
there are jumpers to set the voltage, 3v3, 5v and 12 V , if the wrong one is set it could do damage or simplpy not work
N173HGE-E11 is this work for 40 pins?screen laptop monitor?
Your link for the board is giving a 404 error could you give me a product name of the boards so I can view the different makes.
Really cool. Is it possible to get the screens running at native resolution?
it seems you need to get the board configured for the panel, they all seem to be available, along with the right cable. it is possible to re-program them but I have not figured out that yet. so for now it is easier to just get the one already configured for your panel
I have a LCD Panel ( LTN156AT02-D09 ) If I get that controller board, can i connect it to my computer as a monitor by HDMI cable
based on what i can see of the specifications here www.panelook.com/LTN156AT02-D09_Samsung_15.6_LCM_parameter_22692.html it should work, you will need to set the lvds voltage to 3v3 as indicated in the specifications

Hi, if I’m getting video from the pi over HDMI to an old laptop lcd, how do I also get sound from the pi?
Thanks.
you can get sound from the a/v jack on the PI, you may have to adjust the configuration file to enable it., if the adapter you are using for the old laptop screen has an audio output, this would be a better choice, the PI does also output audio over the HDMI by default.
Looks great. Will the the board work with an old IMac LCD?
I have 2011? iMac I've been saving for some type of project.
Assuming it's the 21.5 inch at 1080p, it should work, as I've seen quite a few consumer PC monitors using that same panel, including the Dell S2218H and HP 22CWA.
So even if you can't find a Chinese no-name board that works with that panel, you may (theoretically) be able to get the control board from a PC monitor that used the same panel model, and theoretically, the same kind of LVDS connection.
@@kbhasi I agree with the responses, post the model / part number of the LCD panel and Ill have a look
I have an old XPS 13 which has a 1920x1080 display. Unfortunately, it seems this controller board is only for 1366x768 even though it'll accept a 1080p input signal. I was excited for a second.

can i do this with tv display .. my tvs motherboard is not working
Funny you should ask that, I am about to try in the next little while with an older LG 42" TV, I have not found any reason why not so far as long as you have the right LVDS cable and a big enough driver for the LED back light
How many amps do I need for the 12v power supply?
It very much depends on what display your connecting and what kind of back-light it uses, but typically between 2 and 5 amps should work for most scenarios.
