IGZO

Most of the hype surrounding the iPhone 5 display has been centered on its size, with industry observers predicting that Apple will increase the next generation display to 4 inches. New information points to an even more intriguing possibility, that the iPhone 5 will feature Sharp's IGZO display technology in a cutting-edge mobile touchscreen.

The diagram above from Semiconductor Portal illustrates the advantage of IGZO transistors. These indium, gallium, and zinc (IGZO) transistors replace standard amorphous silicon thin-film transistors in the Sharp components, which provide higher electron mobility. This means display pixels can be smaller and more light passes through the IGZO display.
