Sony Corporation announced this week that it developed a super-flexible full color OLED display which can be wrapped around a thin cylinder. The new screen is super-flexible to allow it to be repeatedly rolled up, but it's also sturdy enough to still show images. It has a 4.1-inch full colour screen with a resolution of 432x240 pixels and this was achived due to the development of integration technologies of OTFTs and OLEDs on an ultra-thin 20 μm thick flexible substrate and soft organic insulators for all the insulators in the integration circuit. By combining these technologies, Sony successfully demonstrated the world’s first OLED panel which is capable of reproducing moving images while being repeatly rolled-up – around a cylinder with a radius of 4 mm – and stretched.
Sony has not stated exactly what it will use the new displays for, but it has indicated that they may hit the mobile device market. Indeed, the size of the screen itself supports this, suggesting we may have some kind of rollable screen on smartphones in the near future. This may be used to save space or offer bigger screens on small devices by allowing users to stretch the screen out and roll it up when not in use.
