How to define optical properties?

This is looks very good news and it has so many new applications. However, in more demanding applications, optical properties are also equally important. Once OLDEs are stretchable, how one defines optical properties? It must be challenging for designer and user.

CRTs, then LCD/LED/OLED and now it seems that flexible displays will be in the retail market very soon, and that will again start a revolutionary thing, really a remarkable work and achievement by UCLA scientists.

Good ideas all, thanks, but the researchers biggest priority right now is finding a stretchable encapsulaiton method to protect it from exposure to air--which deteriorates all OLEDs. And secondly, to engineer a flexible thin-film transistor (TFT) so the display can be made active--the prototype is passive. Others are also working on these problems as well, in particular professor Zhenan Bao at Stanford University is also working flexible TFTs.

Feedback or Silly Putty?

This is cool! Are they anticipating incorporating feedback as to the distortion so that the image can be adjusted or does it just distort? I can think of applications for both cases, but it seems like serious applications would be likely to benefit from the feedback. I am thinking of a screen folded into 1/4 size initially. Unfold it and the image scales accordingly to take up the entire view. Stretch it horizontally and it expands in that dimension with a wider image.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
