One of the most important innovations in Apple’s latest iPads lies behind the screen. In many of the tablets, the pixels in the display are controlled by transistors made of a material called indium gallium zinc oxide (IGZO), a promising replacement for the conventional amorphous silicon. Displays featuring “backplanes” of IGZO transistors should make it possible for tablets and TVs to have much higher-resolution displays while consuming significantly less power. The technology has already cropped up in low volumes of high-end smartphones and televisions, but its appearance in iPads suggests we can expect IGZO to improve several more popular products over the next year.
