You are a genius! To me this is exactly what RUclips & the Internet were originally designed for - the sharing of knowledge & the demonstration of scientific, technological & anthropological advancements. RUclips needs more channels like yours.
@@Alche987 They're not cheaper, dude. Higher quality, yes. Bright, also yes. The problem is the manufacturing volumes, tollerances and quality checks that make OLED, especially on TVs, harder to produce, but they perform better than LCD screens in phones due to indipendent pixel luminance, energy efficiency, thinness and HDR along with peak brightness and no distortion off-axis. All these things add up to cost and that's why devices such as iphones cost what they do, since the screen is like 400 USD per device.
the pixel grid is part of the color filter in the TFT (Thin Film Transistor) structure. In a typical TFT LCD, the rear glass substrate is divided into many tiny grids, referred to as pixel units or sub-pixels, by a number of transparent metal film wires arranged horizontally and vertically and insulated from each other
You sir are truly amazing, I very much appreciate you showing us the failures as well as victories as this shows us a more realistic expectation. Thank you!
You make great content my friend, keep growing. Most of respect ✊ for your great efforts you to show us how something works. Have a wonderful time and be blessed. ✌️ 👌
For even coatings turn on the spin coating fan and drip a few drops of the solution onto the spinning glass. About 2007 my dad worked for a company developing OLED displays. He was part of the team that worked out the algorithms to increase the current to keep the brightness of the displays consistent as the display aged.
I think you need a lot more of that solution on the glass, for a more even coating when dried. Not for a thick final layer, but before centrifuging. Suggestion: Coat the entire surface with the solution. Then lightly rub it over the entire surface with a swab or similar, that won't harm the conductive layer. This rub/wipe bit is to break through any surface tension that prevents the solution from properly and evenly wetting the plate/layer underneath. Then attach the plate off-axis on your "centrifuge", or you're gonna get a completely different layer thickness across the surface, with pooling in the center where there's a near-dead-spot of centrifugal force. If you attach it at a slight incline angle, that should compensate a good bit for the exponential gradient of speed and centrifugal force radiating from the center of the fan. Just remember to quickly lay it flat again when stopping the fan.
On the next episode of thoisoi2, he shows you how to make a time machine out of no pulp orange juice, a soda can, a microwave oven and an old sock. It's very important that you use no pulp orange juice, because it won't work if you use the kind with pulp in it.
If I live in a jungle and lack e-commerce, which monkey parts should I collect to provide the right proportions of tin and indium when designing such a film?
Nice video! I think you could really improve your results by working a bit on the spin-coating part. For instance you could try to vary the RPM and/or duration. "Quiet Fan" sounds like it might be on the slower end of fans. What annoys me a bit though, is that you apply the substrate with a cotton swap. So uneven, so much heterogeneity introduced there, probably some places started drying a little before you even start the spinning, forming kinda wells where the substrate accumulates. Why not just a big drop in the middle? You could also try dripping the substrate on the plate after it started spinning. Or just use an excess! Fill the whole glass plate with that stuff (by pipette). And if the coating is too thin, add layers :)
Baking soda also works. Seems that in this case it replaces the EIL and you can deposit it onto the existing film with minimal modifications and put the liquid metal on that.
An electrician friend and I made electroluminescent panels in pretty much the same way, except simpler - just two pieces of ITO glass with EL phosphors suspended in oil. We used an audio transformer and a signal generator to get power at 400 hz. It worked quite well. This wss back in the early 80s., dunno if electroluminescent (EL) phosphors are still available from Sylvania, but EL tubing really took off in the early 2000s! Nice video, thank you kindly.
You don’t take your touch screen for granted after seeing this video. Almost makes me want to see what the best led I could build would look like!!! Crap I know, but how crappy is the question? 🤷🏼♂️
A spin-coaster needs to be a lot faster. If cutting the fan blades off isn’t sufficient, I’d buy a cheap ESC and BLDC. Anyhow that’s a really good demonstration!
Chilling here until this become trending and get millions of view. And watch people commenting like they follow this channel from hundreds of subs before it viral.
DIY electronic componants is a fascinating subject. I imagine a resistor could be made from a burnt stick , and capacitors from a sandwich of foil and insulator rolled up, but could we hand make a transistor? THAT'S what I want to know!
Have a LG 55 B6V 4K tv.after almost 6 years i can se some sub pixels are changing.The display is not perfect uniform when it was made.It is not burn in.only when the screen display the color red i can se a thin "curved" line around the senter of the display that is not as red as the rest.Also skin tone this shows up more like a faint green same shape line.They have to improve this.Oled is way better then lcd/led back light display where the problem is led,s buring out but the lcd display itself last longer but have much worce image and a grid pattern that cover around 20% of the surface.Years ago it was 30%,so the number 20 is a guess of improvement.
I thought the rubidium(whatever the long name was) is make the glow, am i wrong? why use a metal alloy instead of directly touching the conductive layer? wish u have explained this.. anyways great video, it really spark my interest in learning more chemistry
If you want to make your own conductive glass coatings buy some vape coils online for like $1 and use them to heat the substance you want to deposit with the glass slide suspended above with a jar over the top. For best results use a refrigerator compressor to pull a vacuum first.

Agreed
That's probably the most sincere comment I've ever read on here. Also one of the most accurate!
RUclips was originally designed for dating.
And I have a hunch the internet was also designed for free porn...
no its for meme
He is scientist/engineer and a good one, enough to can explain it so well.
This is one of the greatest things I've seen and learned in RUclips, a big thumbs up for this totally mindblowing experiments!
he copied it from the internet.
When OLED displays were 1st advertised, they didn’t tell us the organic component would breakdown and fail.
In the end, entropy defeats everything.
@@aianyoung Hahaha...good one...!
Isn't capitalism wonderful.
They still do, but they are cheaper than inorganic, thats why they r selling them now, also you will need to buy new ones sooner

One of your best uploads if not the most interesting one .
Now i know why most oled displays have a copper foil backing
Ha ha I'm from that jungle you mentioned 😓
:o
Me too :))
Oh cool, and you have internet.

Officially impressive results. Great work and very well explained - for average people to understand and follow along. TY :-)
The way RUclips recommended to me is reminding me of I always watching this after I went from school
Very interesting as usual especial the things that did not work at first.
The ascent goes nicely with your word patterns.
Tris(bipyridine)ruthenium(II) chloride dissolving in water under UV is the prettiest thing I have seen this week.
Lmao DIY spin coater made of cpu cooling fan, genious

Channel this big and this technically advanced DIY ... using hairdryers and cheap methods of fire heating to melt stuff. Its hilarious and great

Matey, you are amazing and an inspiration to us all! Who would have thought this possible. Thank you
Bro everything you upload surprises the censored out of me
:D indeed its censored amazing !
Wow wow.

@Musketeer Oliver i got respect because he is European... check my channel and see what you think my philosophy is
This was really cool man! Thank you for sharing this, I enjoyed it.
Amazing !!!. great work , i liked the way u showed u r trials and fails till u figured it out , you are genius , Greetings from Cairo
Great channel for practical knowledge.
I really enjoy how informative your channel is. Thank you for your efforts. Cheers

Love your videos. I learn something new every time I watch your channel.
It's so helpful I will certainly share this video to my all my friends
Wonderful Content. Impressed by your knowledge ✨✨✨✨✨✨✨💛👌
That's definitely pretty sweet
What a beautiful cat :)
Awesome video keep going like that! I always learn something on this channel!
Can you use inkjet printers to print an actual display with better oled compounds?

You'll be really proud if you make a light emitting capacitor next! Applied Science did that, but it should be addressed by someone else.
Your spin-coater is brilliant! :))
What a great demonstration and experiment! Thank you for the video!
Did you put any current limitation?
Maybe it last longer.
Great Video! This must have taken a ton of work -- I hope you keep it up!
Well done. I enjoyed the video and the commentary. Thanks.
4:44 The two on the right have bear faces :D
Great video & nice music.
This is on of your best videos yet.

Hell Yeah!!! RUclips brought me here after searching for poly vinyl alcohol, Im glad I watched it. Thanks for the video bro. Subscribed
This video just made me subscribe to your channel, keep up the great videos!
congratulations!!
Fascinating. More, Thank you!
Thanks man that was another good one.

Came here for the DIY Project, subscribed for the accent
You don’t take your touch screen for granted after seeing this video. Almost makes me want to see what the best led I could build would look like!!! Crap I know, but how crappy is the question? 🤷🏼♂️
Brilliant demonstration, next step a 3 million dot matrix OLED display?
I'm happy and proud that I subscribed
U know I'm seeing this to understand perioic table😁
Loved your centrifugal device
Somewhere Doug Engelbart is smiling down on at least this particular corner of the internet.

Thank you very much
Very cool.
Are there other chemicals that glow other colors?
waterandafter yes, you could even recycle the ultraviolet paint of a "white" led to make an ultraviolet led.
waterandafter white leds are not white, they produce ultraviolet that excite a coating into producing white light.
very good and informative video!
6:40 is such glue is also conductive??
Simply amazing!
This is awesome
this knowledge is way above my pay grade
DIY electronic componants is a fascinating subject. I imagine a resistor could be made from a burnt stick , and capacitors from a sandwich of foil and insulator rolled up, but could we hand make a transistor? THAT'S what I want to know!
Where did you find this ruthenium complex
This is just 10% of what a display actually is.
Dude.. Awesome.. I am do impressed with this. And it's fascinating too..
People struggling with 144hz OLED Displays while this guy builds his own display.
Lol, real DIY is here.
Is it known what LG does to make displays last longer? Also, you could probably stencil out a simple 7-segment display out of a glass plate like this.
Awesome video😊👍
Very impressive !!!
Could you coat fiberglass mattress with teflon ?
If yes , please make a diy video . Thanks
Such a cool experiment
That was COOL!
Wow, pretty cool.
Impressive, you should have made an led while you were at it.

good work!!
dude, that tris ruthenium chloride is very pretty. i want some to paint with, but damn its expensive.
Thanks xx
next make a DIY Led at home. or a DIY Mosfet/transistor?
Why not sandwich the Ru compound between two conductive slides? It will dry slower but it will be more eaven.
Maybe with resistors to limit current you could extend the life by a lot. Even regular LEDs burn very fast with correct voltages but no resistors.
Should you use a current source instead of a voltage source when driving it?
analogdesigner what's the difference?
@@o0AlexG0o a current source prevents "current hogging" as I'm not sure if this device is nonlinear as a diode or LED would be.
Sylvester, get that annoying squirrel to Natasha and me!
Another awesome video :)

Could you use the sputtering process on glass slides to put a fine layer of metal on to act as the conductive surface?
Such a great video and experiment...
lol you're the hydraulic channel guy!
ik this is probably a joke, but the hydraulic press channel guy is Finnish, and thoisoi is Russian
Have you tried using AC current instead of DC? This might prevent substance decay, as in LCD screens.
It''s wonderful and easy explain! Congratulation!
This is amazing!
