Sony Develops a “Rollable” OTFT*1-driven OLED Display that can wrap around a Pencil
Sony Corporation (‘Sony’) announced that it has developed a super-flexible 80 mm-thick 4.1-in 121 ppi OTFT*1-driven full colour 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 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 mm 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.
