Sony demos very bendy flexible OLED screen
Wrap it round a pencil and it'll still show video
Sony has developed an OLED display that's just 80 microns thick, allowing to be bent round anything with a radius of 4mm or more - and to continue to show moving images while this is happening.
The prototype panel is just 4.1in across, with a 432 x 240 resolution and show hues from 24-bit, 16.8m-colour palette. It has a 1000:1 contrast ratio and a brightness of 100cd/m2.

Sony said the material may one day form the basis for flexible displays and e-paper.
The OLED is made using organic semiconductor compound peri-Xanthenoxanthene (PXX) formed into thin-film transistors. PXX is stable under exposure to oxygen, moisture, light and heat, Sony said, though it didn't state what kind of longevity the OLED panel has.
Current OLEDs eventually fade, particularly in the blue part of the colour gamut.
Indeed, Sony admitted that it needs to improve the reliability and performance of the display, though it claimed that even after 1000 cycles of repeatedly rolling-up and stretching the display, there was no clear degradation in the display's ability to reproduce moving images.
It also said it is working on a way of printing the panels, laying down components from organic semiconductor compounds "dissolved in common solvents". This, it believes, will make for a manufacturing process that is more environmentally friendly than is the production of silicon chips. ®

Screw all this pointless iPaid masturbation - THIS is more like it
Enough of this iPaid (through the nose) nonsense, THIS is more like it.
So you can touch your phone and, umm, buy a bigger (WTF?) - I want one with a roll-out screen. Now THAT is cool.
Useful for political broadcasts then, with minimal discomfort.
While a political broadcast is playing, I can roll it into an 8mm tube, insert it into any available arsehole and let said political broadcast be viewed directly by the appropriate organ.

You get your thrills when you least expect 'em.
Brilliant!
That is truly impressive. I wonder if it can be rolled or bent in the other direction too? Either way it has a million potential uses in having a screen that can be just wrapped around anything or can be worn. Hopefully a digitiser could be incorporated too, then I can have a lightweight interactive notepad wrapped around my forearm & wouldn't need to carry a smartphone and/or laptop around all day.
