A DIY OLED Display Really Surprised me! 

You are a genius! To me this is exactly what RU-vid & the Internet were originally designed for - the sharing of knowledge & the demonstration of scientific, technological & anthropological advancements. RU-vid needs more channels like yours.

This is one of the greatest things I've seen and learned in RU-vid, a big thumbs up for this totally mindblowing experiments!

When OLED displays were 1st advertised, they didn’t tell us the organic component would breakdown and fail.

Now i know why most oled displays have a copper foil backing

Ha ha I'm from that jungle you mentioned 😓

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!

One of your best uploads if not the most interesting one .

Officially impressive results. Great work and very well explained - for average people to understand and follow along. TY :-)

The way RU-vid recommended to me is reminding me of I always watching this after I went from school

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

Fascinating. More, Thank you!

Matey, you are amazing and an inspiration to us all! Who would have thought this possible. Thank you

This was really cool man! Thank you for sharing this, I enjoyed it.

What a great demonstration and experiment! Thank you for the video!

Very interesting as usual especial the things that did not work at first. The ascent goes nicely with your word patterns.

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.

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. ✌️ 👌

I really enjoy how informative your channel is. Thank you for your efforts. Cheers

Lmao DIY spin coater made of cpu cooling fan, genious

Love your videos. I learn something new every time I watch your channel.

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

Tris(bipyridine)ruthenium(II) chloride dissolving in water under UV is the prettiest thing I have seen this week.

Simply amazing!

Great channel for practical knowledge.

Thanks xx

This is on of your best videos yet.

Thanks man that was another good one.

That was COOL!

congratulations!!

This is amazing!

Dude.. Awesome.. I am do impressed with this. And it's fascinating too..

Well done. I enjoyed the video and the commentary. Thanks.

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

Loved your centrifugal device

Such a cool experiment

Another awesome video :)

Pretty cool!

Wow, pretty cool.

Bro everything you upload surprises the censored out of me

Thanks for sharing these knowledge with us😍.....

Such a great video and experiment...

- Mom, I want to buy a new TV - But we already have one at home. *The TV at home:*

This is awesome

Oh wow!

It''s wonderful and easy explain! Congratulation!

wow .... really great

VERY interesting! 👍

I didn't forgot to give the thumbs up after all you deserve it, thanks.

I'm happy and proud that I subscribed

So fricken cool man, nice work

good work!!

Hell Yeah!!! RU-vid brought me here after searching for poly vinyl alcohol, Im glad I watched it. Thanks for the video bro. Subscribed

very good and informative video!

Awesome video😊👍

ur awesome buddy!

This video just made me subscribe to your channel, keep up the great videos!

What a beautiful cat :)

Amazing

Excellent

That's definitely pretty sweet

fantastic

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.

Superb video

INCRÍVEL ❤️❤️❤️

Bravo!

Pretty cool man..

Thank you very much

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.

4:44 The two on the right have bear faces :D Great video & nice music.

This is very nice

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.

Could you use the sputtering process on glass slides to put a fine layer of metal on to act as the conductive surface?

Have you tried using AC current instead of DC? This might prevent substance decay, as in LCD screens.

this knowledge is way above my pay grade

I like your cat! 🤗

Did you put any current limitation? Maybe it last longer.

Amazing video, as always, you made a great progress in clearing your pronunciation, but that was never a problem, I am not a native speaker but I always was able to understand you, also, very cool displays!!! Q: What could be done to extend their life with the minimum cost?🤔 And as always, continue with the amazing work in exploring chemistry, you are the reason for me getting a great mark at school projects!

People struggling with 144hz OLED Displays while this guy builds his own display.

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.

Was a Subscriber since years, but It's time for an UPGRADE

Very impressive !!! Could you coat fiberglass mattress with teflon ? If yes , please make a diy video . Thanks

What if you apply AC voltage?

Sei una forza!

Can you use inkjet printers to print an actual display with better oled compounds?

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!

Wouldn't sputtering be better to use for the coating?

6:40 is such glue is also conductive??

couldn't you use the conductive glass for both electrodes and sandwich the colored glue between?

It's recall me artististic wide panel in ISE restaurant. At first glance seems epoxy resin but can't be for backlight absence. Still impressive like yours, but the works since years.

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.

Where did you find this ruthenium complex

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.

U know I'm seeing this to understand perioic table😁
