On the past we wrote an article about flexible paper thin AMOLED and transparent displays. Samsung Mobile Display, produced recently, a new short Video (in Korean) showing a transparent, flexible 3D AMOLED display based tablet. This is obviously just a concept device, and it'll take years before they'll be able to commercialize something like that, but it's still very cool.
Flexible OLEDs are still not available, but Samsung does plan to start producing these in 2012. The first screens will probably not be bendable ones, but Samsung will be able to produce them on curved surfaces. Several other companies (including Sony, AUO, LG, HP, Toshiba, TDK and others) are working towards flexible OLEDs.
This technology is exciting device makers, too - check out Nokia's Kinetic prototype - a completely flexible mobile phone :
The idea is that you can bend and twist the whole device to perform certain actions : for example bending it towards you is used to select an option or zoom-in on an image.
Nokia didn't say what kind of display technology is used in this device , but it's most likely a flexible OLED.
The display is 4" in size and has impressive viewing angles according to reports. In the past two years we've seen several companies present flexible/bendable OLED Prototypes: Samsung, LG and UDC, Toshiba, Sony, AUO and the FDC with UDC. Nokia is already buying AMOLED panels from Samsung and LG, so it's likely they are collaborating with one of the Korean makers. Apple is also interested in such displays.
Transparent OLEDs have been commercialized already actually - TDK is producing 2.4" PMOLED screens, and the first product to use them is Lenovo's S-800 phone. But these rigid and simple displays are a far cry from what Samsung shows us in this concept. Enjoy the video!
