Old laptop Screens on a Raspberry PI... Part 2 :// • Old laptop Screens on ...
for the longest time my answer has been NO, or not with a lot of work
It is now time to change that answer, in this video you will see how you can use many different LCD panels from OLD Laptops with the raspberry PI with the purchase and connection of a simple board from Banggood.
This is not a sponsored video, I bought this board and some others that are still on their way, and I wanted to share with you how to get everything working.
the board I bought can be found here:-
www.banggood.com/custlink/3DK...
using this link will help me run the channel if you then purchase from Banggood. I will get a small commission but you pay no more.
use this link for other items from Banggood.

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"!
This is awesome! It solves several problems I have in my RV (Caravan), so I thank you so much!
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!
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

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!
I've been waiting for this, thanks.
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!
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.
It works for all the displays with that connector. I believe that smart phones use different connectors...
Great to know! Cheap display controller board too! Thanks for posting the video!
Important stuff. Please make more.
good video was wandering how I would do this now I know spot on
very cool also a great way to fix a monitor that has a bad driver board
This is going to work perfect to use my Galaxy S8 a little semi-portable computer.
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.
Congrats
and welcome to the re-purposing club :)
Great bit of education, thankyou.
Prolly rhe nicest guy in the world.🙏🙏🙏
Thanks
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.
Great job thanks
Thanks Peter that was really interesting, regards RobUK
For the one with the broken backlight, you can make it into a projector.
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 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."
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.
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
You filled in a blank spot for me as I have a hinge on my LT broken but little money to put in it
Great Video
Is there any effect of lowere ampered adapter to the function of the controller? Is lower amper causing not functional LCD sceen?
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
Excelente!
Very interesting, but I don't follow how you determine which LCDs work with which boards and or cables.
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.)
if it is a 50 pin cable and a small ish lcd display, then it may be a TTL type input to the panel rather than LVDS, check on panelook.com for details.
Can I use the control board you mentioned for a screen model LP156WH2(TL)(AA)? Do you need a separate power source for the control board
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?
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
Can you set it to use the native resolution of the panel?
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!
Can you please go into more detail? Are the controllers standard or specific for each monitor? Where do you get the from? Etc. Cheers.
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
@@sendittozach Thank you for the reply. Have a great day.
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!
Certain "BenQ" monitors are ideal for building an LCD projector as there is nothing blocking clear light coming thru the panel.
You gut the panel and nothing blocks the light in any brand.
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
you are a awesome guy
I went to France and it wasn't very French. I was so sad. Please do something soon.
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!
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
ordered my self control board for my 1080p 60hz screen, i built mitx pc and needed reasonably portable screen. Should work fine for my needs.
Kinda wished I kept those LCD panels.
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,
How do you determine weather it is a 2-channel or 4-channel?
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.
how do I use the wacom digitizer (su5r12w04au01x ) on my od lapto screen? the laptop "was an hp tx2000, thanks.
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.
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!!
will this board work with b156xtn02.0 model lcd
Can this work with Samsung ltn156at05-h01
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.
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 .
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 :)
great vid mate, btw any idea how can i reuse my x550DP from an old asus laptop.. thx lots
$20 board plus laptop screen vs a thrift store monitor
which will be more cost effective?
I'm thinking the thrift store
Bro you have any idea how to connect a smartphone motherboard lcd connector to connect a 15 inch laptop lcd panel with digitalizer.
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.
This board have been discontinued, so no way yo buy the same product. Any news on upgrades/replacement? Thanks :)
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?
Finally. :)
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 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
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.
N173HGE-E11 is this work for 40 pins?screen laptop monitor?
I have tablets that will not boot, will the screens work ?? I do not want to put a lot into it! I'd like a HDMI screen, or b
Cast by phone on the screen, is this possible?
I think that is the same osd that my car's flip down tv uses. I have taken it apart and I saw a empty VGA header on one of the boards.... Hmmmmm...
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 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
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.
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
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
I agree that these boards are nothing new but your video is nonetheless excellent. As a society we need to throw less away and reuse what we can. I have several old laptops I need to do something with. Batteries for building a powerwall and screens for displaying stuff round the house. A pi zero should make a good controller for a display screen on the wall.
I have seen references online to overlays you can put over a screen that add touch functionality, but I cannot find them, my search terms are probably wrong, Anyone got any ideas on that?
And did anyone say magic mirror?
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
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.
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
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 Man !
I am curious if it is possible to use dead mobile's LCD Screen with Raspberry Pi?
Thoughts?
Epic video ! Thanks for the vid !
Do you know how to make custom PCB’s
I do but have not done so for a few years, I was thinking about doing a colab with PCBWay or an other vendor to get back into it
@@TheBreadboardca jlbpcb does a lot of sponsorships.
7:45 Focus you frack! With a homage to AvE
LOL, yess indeed
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
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.
Lcd controller board link is broken. Can you post an updated one or give the name of the board please?
Hey there would you be willing to educate me on a screen I'm looking to use it's an old dell laptop screen
What is the make and model of the screen ?
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
Hey i have a display screen of LG model LP156WH4 TLC1 and its a 40 pin can it be working with a 50 pin controller board ?
the display is pretty much the same as the ones I used on the video, 1366x768 and should work with any of the controllers I showed in this and the later video, the trick is to ensure the cable is correct, single channel 6 bit 40 pin lvds. the connector at the controller end in my case is 30 pin (2X15), but controllers also sometimes have a flat direct connect cable too and this could be 50 pin. do you have a link to the board you are considering, if so reply to me with the link
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,
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.
Does the controller run hot? Does it need a heatsink?
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.
Can u do video how to use old desk computer screen on r pi 4 (screen is working)?
Yes I can and will very soon, just getting parts together for it. ordered them already.
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!!
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?
Do you know if you can get them somewhere with faster delivery? Most are nearly a month 😂
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.
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
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
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
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
