More info on AUO double-sided AMOLED

Mobile phones could soon be getting a new look if a double-sided organic display developed by AU Optronics of Taiwan proves popular. The new active-matrix organic display (AMOLED) generates 1.5 inch-sized full-color images on both its front and rear surfaces and is controlled by a single IC driver chip.

In the new AMOLED structure, the sub-pixel area is divided into two regions designed for top-emission and bottom-emission. A transparent layer of indium tin oxide (ITO) is used as the anode in the bottom-emitting sub-pixels, while a reflective Ti/Al/Ti/ITO sandwich-type structure is used as the anode for top-emitting sub-pixels. Each side of the display has a resolution of 128x120 pixels, 16-bit color and a brightness of up to 150 nits and is capable of showing independent images.
