Last week, released a video of their new flexible display, with a total width of 0.3mm. After scouring the official sony site (where I can't find any mention of the device) I found the following video on Youtube

The display uses a mixture of OLED and TFT technology (according to news sources) - Basically this means that the display is a large matrix of printed dots made from an organic chemicals which show Electro-luminescence (i.e. they glow when a voltage difference is created aross them). This is very different from LCD technology, where the display is backlit separately while a layer of Liquid Crystal is used to change the properties of the light for each pixel.

Groups of red, green and blue dots form one pixel, and they are addressed using the TFT technology, which uses a tiny transistor connected to each dot to drive the electro-luminescence. This means they can be addressed by what is effectively a continuous potential across sections of the display, rather than by running individual connections to each dot. This enables much faster and cheaper switching of pixels.

It is noted that this research is still far from the bistable paper-like devices that many companies are still researching, which would hold an image even when the power is disconnected. The display is 2.5 inches wide (a fairly standard size for prototypes), and allows video playback(see video).
