I'm trying to find somewhere I could buy flexible displays? I really have no idea if these are even that common or available....I know they exist. I'd like to be able to incorporate flexible LCDs into clothing. Don't need anything fancy. Monochrome would do, backlit would be nice.

Any ideas?

they are really hard to come by.

the ones I have seen are by E-Ink. Their flexible displays are monochrome. They have two different types. One which sort of has the flexibility of a plastic sheet or heavy cardbord. These seem to be more or less identical to the regular e-reader displays, except that you can bend them to a certain degree.

The other type is really cool. Its super thin and can be roled or crumpled. However, this screen can only cycle through pre-programmed images.

Both are really hard to get your hands on, I would not be surprised if the second type had never been handed to third parties at all yet. (As its really cool, but as of now far from actually usefull ... well ... at least the last demo I have heard of, which is a while back.

*

Then there are a bunch of oleds floating around, where again you seem to have the same problems - they are either fairly stiff, or really flexible, but (and I dont know this as a fact, but I am quite sure) the really flexible ones probably only display pre-programmed sequences.

Also, while both sony and samsung build them, I am quite sure, that they dont actually own the patents to the technology. I have not however been able to figure out who actually does.

Anyway, again. Really hard to come by. I would not know how to get them...

anyway, sorry I cant really help you except with random trivia.
cheers

(oh, but maybe instead go low res and use programmable rgb-led strips?)

that video is hilarious!

there is also LCD paint you can buy. If you want it monochromatic, you only need one layer of paint.
I think it's becoming scarce, however, I couldn't find it last time I looked.

LCD paint?

can you explain how that works? how would you operate it? how would you create the backlight? what would you use it for?

You paint it onto fabric, if I recall, painting it onto dark fabric helps with the backlighting issue.  Last I saw it, you could buy it in different colors, and each color required a different temperature to activate the color change.  You can stick wire into the fabric and vary the resistance from the battery to get the different temperatures.  It would be really difficult to attempt anything like video, but text is reasonable. 

I don't know where you could buy it if you're interested, if anyone knows, lemme know.

Any new developments on this topic?

Thanks

well... not so much for us hobby-ists. I had my hands on a FOLED this january, at TEI, but I know for a fact that the guy who organized it had been lobbying for 5+ years to get it...

the technology is advancing... but I know of no product which one could simply buy without signing a NDA first... :-(

Also, I had heard reports that Samsung would be releasing a Flexible OLED display sometime in 2012 a few years back. Here is some recent news I found on this...

I think you are thinking about "thermochromic paint"; you paint it on a surface, embed regular wire (or resistance wire), and as you pass current through the wire, the wire heats up, and the paint changes color. I did a google search for the stuff; it doesn't seem scarce (though it may be difficult to get - I didn't try to track any down).
I will not respond to Arduino help PM's from random forum users; if you have such a question, start a new topic thread.

..thermo-chromatic paint...


Hi, these guys in UK do it. Should be someone in your locale, this is an education website for schools and colleges.

Thermo-chromatic pigments link (UK):

They do lots of other nice stuff too, to do with science,tech, arts and craft. They even have an arduino called a faraduino.

Cheers

Edit: PS is that video really real ? Wow!

Its been a while.

LG Flex is out there, but ... the display is fused to the plastic, which is not all that flexible.

I tried removing it and failed.

Has anyone else had more luck? Anyone stumbled across any new modules? I found this here: http://www.aliexpress.com/item/1-66-flexible-oled-display-SEPS645B-24PIN/1988374737.html

considering testing it, but actually interested in something bigger.

Sorry to barge in,
how flexible are eink panels such as http://www.aliexpress.com/item/LB060X02-RD01-E-ink-display-flexible-bendable-score-screen/2048991808.html ?
