Sony Rollable OLED Display  (Source: Sony)
New screen is easier to build than previous flexible OLED screens

Sony has long been working on a new generation of displays that are flexible enough to be bent and shaped around an object. The first of these flexible OLED displays to be seen from Sony surfaced in 2007. The display offered 16.7 million colors and was 0.3mm thick with a resolution of 160 x 120 and a 1,000:1 contrast ratio.

Sony has now announced a new breakthrough in flexible OLED displays that puts the 2007 unveiling to shame. The new screen that Sony has debuted is only 80nm thick and can be rolled around a pencil while displaying images on screen. The screen measures 4.1-inches and is a full color display. To create such a thin display, Sony used a new organic semiconductor material it developed called peri-Xanthenoxanthene (PXX).

PXX is important to the breakthrough because it is stable when exposed to oxygen, moisture, light, and heat. It also has an improved current modulation of eight-times compared to conventional organic semiconductor material pentacene. The new display is also the first flexible organic thin-film transistor (OTFT) that uses an integrated flexible gate-driver circuit.

The integrated flexible gate-drive is key because it allowed the removal of the ridged driver IC chips used in other displays. The design process also uses new organic insulators that can be formed in the atmosphere requiring fewer steps to produce making the construction process less time consuming and more efficient compared to traditional vacuum semiconductor processes.

Sony claims that the flexible display can be repeatedly rolled up to a radius of 4mm and stretched as many as 1,000 times without degradation in the ability to show moving images. The display can show over 16.7 million colors, has a contrast ratio of around 1,000:1, and a peak luminance of 100 cd/m2.

Cool, But...

It's really cool, but I can't think of a single practical use.

maps for the military that can recieve OTA transmissions updfating current evac zones/hot zones and safe areas, base locations, objective and directions, or simply a mobile display unit for diagramming out an attack strategy on the fly, or getting the information from HQ about how the op goes

alternately, watch the movie "The Red Planet", you will see practical uses for something like this there.

alternately, Wal-Mart sells imaginations i think, you could buy one :)

There are endless uses. Here's one that just popped up in the head: First page of a notebook being OLED(storing the textbook as an ebook)

Exactly. It's answer to the problem that nobody's had! Doesn't mean that we'll never have the problem, mind...

I can think of 50 uses off the top of my head, more if it could be a flexible touch screen.

Hell, it doesn't even matter that they ARE flexible... look how thin the damned things are.

Where's your imagination?

It's not that, you just have far more problems than I do.

What I can't figure out is the lines in the screen. It is an awesome concept and I really got excited when I read about it... until I watched a video of it in action...

There are lines in the display that really detract from the image quality.

Yeah, but I'd assume that they'd iron a lot of that out as they develop the process and get close to a release.
After watching the video they are really noticeable though... and they appear horizontally and vertically.
