Sony unveils super-thin OLED screen that can be rolled around a pencil

By Daily Mail Reporter

Sony has developed was it calls ‘the world’s first’ flexible colour video screen, that is so sheer it can be rolled around a pencil.

The Japanese electronics giant created the 4.1″ across prototype using an ultra-thin flexible material covered in organic semiconductors.

The OLED screen has a 432 x 240 resolution with a 1000:1 contrast ratio and a brightness of 100cd/m2.

The ultra-thin screen continues to show a clear picture even when it is rolled

A video shows how the 0.08mm thick screen continues to show clear moving images even when it is rolled in and out.

It could one day be used in a host of flexible mobile devices, television, electronic newspapers and magazines.

‘Even after 1,000 cycles of repeatedly rolling-up and stretching the display, there was no clear degradation in the display’s ability to reproduce moving images’, a Sony spokesman said.

Sony is not the only Japanese firm developing long-lasting flexible displays. Public broadcaster NHK have worked on similar techniques in recent years.

Japan’s department of New Energy and Industrial Technologies (Nedo) is also leading a research programme in a bid to create a manufacturing chain for the displays similar to the way newspapers are printed.

The prototype screen will be presented at a conference tomorrow on the sidelines of the Society for Information Display (SID) exhibition in Seattle.
