Sony is currently working on 4.1 inch foldable display which looks like something from the movies of the future. The display can be completely wrapped around a pencil and unwrapped to full form.

To create the display, Sony developed OTFTs with an original organic semiconductor material (a PXX derivative) with eight times*2 the current modulation of conventional OTFTs. This was achived due to the development of integration technologies of OTFTs and OLEDs on an ultra-thin 20 ?m thick flexible substrate (a flexible on-panel gate-driver circuit with OTFTs which is able to get rid of convetinal rigid driver IC chips interfering roll-up of a display) and soft organic insulators for all the insulators in the integration cuircuit. By combining these technologies, Sony successfully demonstrated the world’s first OLED panel*3 which is capable of reproducing moving images while being repeatly rolled-up – around a cylinder with a radius of 4 mm – and stretched. Sony will unveil the results of this development on May 27 at “SID (Society for Information Display) 2010 International Symposium” in Seattle, WA (May 23-28).
