Thanks for including the Samsung link--I've been meaning to include them in the discussion--and you're right on both counts: their demo was very impressive, but of course the encapsulation technology will be the critical factor in how soon they can come to market.
Pei said it in the article: "The second key development is an OLED architecture that we call light-emitting electrochemical cell [LEC]. The LEC devices use a thin luminescent layer that is actually a mixture of electronic semiconductor and an ionic conductor." These devices are not like traditional colour display pixels; they don't have addressability and they don't have multi-colours (i.e. RGB) so cannot display any reasonable gamut of colour range. So these are essentially lighting panels, and the particular ones shown here are yellow. The light emission comes from the polymer, phenyl substituted poly(para-phenylene vinylene) known as "Super Yellow," (you can purchase it and make your own). Even though they show "pixels", note they are not able to light them individually, and a screen made of these would really resemble something very old! -> https://en.wikipedia.org/wiki/Monochrome_monitor
@docdivakar I would be curious to know if there are any optical behavioral shifts with stretch ratios? And does it vary with time?
I believe most of the stretching durability tests were performed on the light panel rather than the display prototype, so no data on optical behavior shifts or time variance properties yet. Also the researchers next concentration is finding an encapsulation method that can stretch as easily as the LEC.
It seems like the technology shows good promise. There are many open questions for this before product designs can start. I would be curious to know if there are any optical behavioral shifts with stretch ratios? And does it vary with time?
We are witnessing another type of display technology take shape -light-emitting electrochemical cell (LEC)...
chanj, i agree that some technologies are faster to integrate in consumer market but other such as 3D LED have failed despite all the hype and maturity. Sometime the price at which the technology is sold is not enough and technology support and peripherial support is more than necessary.
I can see a lot of applicable area and I do agree that the talk of application may be premature until the technology is commerically viable. Nonetheless, who knows how soon the technology can be commerically viable? I have noticed lately that technology is widely available sooner than before. Just look at OLED itself, the pace is far exceeded that of LCD. The market welcomes small OLED display on mobile device, then large TV.
I think that until the technology - whatever that maybe - for curved and flexible displays becomes commercially viable the the discussion of which applications will benefit is somewhat premature. Sure, flexible display technology will come at some point in the future...consider that the first LCDs were prototyped 40-50 years ago and perhaps only now have they become ubiquitous.
