Sony’s new “Rollable” OTFT-driven OLED display can wrap around a Pencil

Sony developed a super-flexible 80 ?m-thick 4.1-in 121 ppi OTFT-driven full color OLED display which can be wrapped around a thin cylinder. “To create display, Sony developed OTFTs with an original organic semiconductor material (a PXX derivative) with eight times current modulation of conventional OTFTs. This was achived due to 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’s able to get rid of convetinal rigid driver IC chips interfering roll-up of a display) and soft organic insulators for all insulators in integration cuircuit,” writes Sony.

By combining these technologies, Sony successfully demonstrated world’s first OLED panel 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).
