SonyInsider reports that Sony has developed an ultra-thin, super-flexible 80µm-thick 4.1-inch 121 ppi
OTFT-driven full color OLED display with16 million colors, shown here being wrapped around a thin cylinder. This gives Sony a lot to brag about when they hit SID
(Society for Information Display) 2010 International Symposium in
Seattle, WA this week. We can only imagine the innovative gadgets that will be created in a few years using flexible, rollable displays like this. Check-out the video below.
To create the display, Sony developed OTFTs with an original organic semiconductor material (a PXX derivative) with eight times the current modulation of conventional OTFTs. This was achieved 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 conventional rigid driver IC chips interfering roll-up of a display) 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 repeatedly rolled-up – around a cylinder with a radius of 4 mm – and stretched.
