Making an OLED - Light from Carbon Compounds

[koncertLive]

can someone please use her as a point of reference to demonstrate the "IR SEE THROUGH CLOTHING TECHNIQUE" Brainy

I submit this as evidence that brainy chics are hot!!!!

[FlippinFlaves]

First of all, I always enjoy your videos. They are very informative if not a little over the head of an amateur synth-builder such as myself. Anyway, I was wondering if there is any way to create an OLED with selective luminescence such as a flexible 7-panel display for numerals, etc. Do you know of something like this?

[spokehedz]

6:17 - And this is why we do not use single-edged razor blades without a handle, Jeri!

[theonelinerkid]

where do you ge the stuff to make all of this?

[bitmerge6502]

transparent OLEDs are going to be in every digital device before too long.

[bitmerge6502]

i've been wanting to try this forever. most totally awesome.

[satellitetune]

Great vidio

[TheWholefoodfarmacy]

Great vidio

[SeemannCustom]

Author, you are beautyful!

[TheRobert188]

realy cool better then school

[TheKC1ML]

Your amazing Jeri, and I have no idea what you just said LOL.

[opl500]

I wonder, if you can make diodes with these materials, it should be possible to make transistors too?

[jeriellsworth]

@opl500 There is a lot of research going on in this area.

[femtophysiker]

@opl500

Yes, we can!!!

[deuxcreed]

nose bleed lol

[crygamer2]

Is it possible to purchased these chemicals from some where?

[jeriellsworth]

@crygamer2 Polymertronics sells a complete kit.

[crygamer2]

@jeriellsworth Thanks

[Jerzz2020]

1:55 Pick up paper fail

[DemokritosAbdera]

You really have access to slick chemicals, i can barely get anything in my country :(

[dentsanddivots]

Ugh... i was soooooo thrilled you found the repeat function on your movie editor that i signed in just to comment on how: a) you're just spouting off what you read in some textbook without actually explaining the concepts (btw, i'm well familiar with them) b) who do you think is watching this video? granola liberals who are looking for a solution to complete their organic lifestyle? duh we know that organic doesnt mean what most (women) do and c) there are NO SUCH THING AS HOLES!

[jeriellsworth]

@dentsanddivots Hehe. Love you too. Misogynists are not welcome here. Blocked. BTW. You will have a hard time ordering your OLED materials if you refer to the hole transport layer as the "NO SUCH THING AS HOLES! Layer"

[CampKohler]

@dentsanddivots Har, har. She really gave you the what for! As for who is watching, I am a retired techie just hearing about OLEDs and want to learn at least the basics (preferably without equations). Better to hear it from a pretty girl than some dry text.

I understand they are the cat's knees for new TVs, although very expensive now..

[telesniper2]

Hm, I never knew Gallium and Indium were "organic"

[jeriellsworth]

@telesniper2 All commercial OLED's on the market today have low work function metals for the back conductor. Elemental calcium is common.

[AmazGraz]

Hey girl! Shhhh, I'll whisper, (you popped up at the end looking really good there, prettty, and smart! Uh huh.)

[vietlaws]

can u now teach me the next step in making a oled tv =P

[Deathless2288]

Cool stuff, thanks.

[BarsMOnster]

@jeriellsworth : Jeri, you've scratched the surface a very interesting topic - bandgap of different materials(metals, semi, dielectric, how contacts between them works), how it's affected by doping, light transparency, reflection. That woudl be super-educative to see a video about all these things, in 5 minutes ofcourse :-D

[zzanzak]

I Love You

[markiduval]

I feel super educated now.

[jeriellsworth]

@markiduval This one was very dense. I was trying to keep to my rule of 5 minutes or less.

[markiduval]

@jeriellsworth Indeed. Complicated but interesting stuff. You inspired me the other day to buy a hobby electronics kit from thinkgeek. Looking forward till my holidays next week when I'll have time to play with it.

[g7gij]

imagine the fun you could have with bucket of OLED polymer and a paint roller,

no glass skyscraper would be safe.

[jeriellsworth]

@g7gij Graffiti of the future. Spray paint cans of OLED materials.

[adechiaro]

Jeri you've done it again, thanks for all the great work you've done plus taking the time to document and explain to us all so well. I'm looking forward to watching the next video you upload!

[hacktheplanet90]

Jeri Ellsworth:Chemical Genius 

[DanFrederiksen]

nice. a little refinement in the process would probably be good to have a more even light surface

[jeriellsworth]

@DanFrederiksen Indeed!  I was sparing the alloy and dye, so I don't run out before trying a few more experiments.

[itchesavvy]

I thought you'd like to know the inspiring effect you had on my 7 yo daughter last night. I was watching this vid while getting them ready for bed. She heard you say Magnesium and Cesium and ran out of the room. She returned with her periodic table she had pulled down from the wall in her room, and then began to follow along with the vid. She later found Ruthenium, Boron and Flouride.

[jeriellsworth]

@itchesavvy Sounds like you have a future scientist on your hands!

[joshcryer]

Oh man, the end got me. This video is awesome. We need more people like you!

[erikaustria1974]

Great Video! I will post it at our OLED-Info website

[Afrotechmods]

This was more interesting than everything I've watched in the past month put together.

[jeriellsworth]

@Afrotechmods Awe shucks.

[v2keener]

So cool. Really enjoy knowing a little about the difference between florescence and and phosphorescence

[XsavioR38]

Nice work again, Although I like the results of the flexible one better.

[jeriellsworth]

@XsavioR38 This one can be done on a flexible substrate too. I'll have to do a follow up video after I try my other experiments with the Ru complex.

[catman72]

this is great stuff, i'm waiting for the glow-stick version, much more available... :-)

may i ask if you can show how to make a TEC element?

[jeriellsworth]

@catman72 I looked at them once. I'll have to see what they take to make again someday.

[drOffset]

I wish I had this info years ago before buying that engagement ring! Thanks for the knowledge Jeri.

[NurdRage]

Ah CRUD!!!

*I* was going to build an OLED! You beat me to it! :)

Now i got $500 of useless materials! :)

Great video though, i applaud your work.

[jeriellsworth]

@NurdRage Your video will be much better!  You have a way with pitch shifted words!

[sonicase]

lol 1:56

can't wait for the glowstick one

[orbiter8]

Thanks for taking the time to do these vids Jerie, very informative as always.

[Gameboygenius]

3:09 right when you mentioned calcium, together with the pointy finger, I got reminded of Look Around You.

Thank you ants.

Thants.

[Gameboygenius]

2:45 Notice how the green light actually makes the red tube fluoresce, which mixes with reflected green light and gives yellow light.

[jeriellsworth]

@Gameboygenius It's possible there is absorption in that material. I could not identify the chemistry from the glow stick companies patents. 

[K0W0O0N0]

That is very cool :-]

What exactly makes the glass conductive?

Cheers...

[jeriellsworth]

@K0W0O0N0 At the end of the video I have a link to my conductive glass making video. It's a thin layer of tin oxide doped with indium..

[JimmerSD]

The technology of OLED has come so far in the last couple years. It has been quite the buzzword. Thanks for putting a face with the name.

[bobcat0]

Another source for low temp melting point alloys is a mercury-free glass thermometer from a drugstore. They contain Galinstan , a gallium indium tin alloy that is liquid at -2F.

[jeriellsworth]

@bobcat0 Cool. Does it look silver? I only see red alcohol ones these days.

[bobcat0]

@jeriellsworth Yes, looks just like the old mercury ones.

[scafativ]

@jeriellsworth They seem to have them at Wallgreens:

Do a search on Galinstan  on walgreens website

[khisanth75]

Learning so much from your videos Jeri, really appreciate how well you explain things. My chemistry and physics knowledge is flooding back!

[jeriellsworth]

@khisanth75 I should put disclaimers that say "Caution. This info can be incorrect for no apparent reason."

[khisanth75]

@jeriellsworth that would spoil the illusion though ;)

[TheEricBooth]

@jeriellsworth That has to be theee best disclaimer ever.

[clintfisher]

Nice video Jeri! Very informative.

[tonsilol]

Well explained!

1:56 reminds me of vinyl times

[Matthiaswandel]

Don't you hate it when you do voice overs after the fact and the footage you shot just wasn't quite long enough!  :)

[jeriellsworth]

@Matthiaswandel Gave me a chance to be silly.

[PhattyMo]

Love it! :)

[ubuntututorials]

awesome.
