Sony Develops a “Rollable” OTFT-driven OLED Display that can wrap around a Pencil « Akihabara News

Sony Corporation ‘Sony’ announced today that it developed a super-flexible 80 μm-thick 4.1-in 121 ppi OTFT1-driven full color OLED display which can be wrapped around a thin cylinder.

To create the display, Sony developed OTFTs with an original organic semiconductor material a PXX derivative with eight times2 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 μm 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 panel3 which is capable of reproducing moving images while being repeatly rolled-up – around a cylinder with a radius of 4 mm – and stretched.
