Korea IT News’s Mun Bo-kyung reports that Apple will expand its adoption of IGZO (indium gallium zinc oxide) displays in order to diminish its mobile devices energy consumption, citing industry insiders who,say that having decided to bring the IGZO method to MacBook displays for, Apple is talking with IGZO LCD panel manufacturers, notably Sharp and LG Display.
Mun Bo-kyung notes that IGZO, an oxide semiconductor, is used in TFTs (Thin Film Transistor) that control a supporting (but non-conducting) substrate such as glass, and that oxide semiconductors are about 10 times faster in electron mobility than a-Si (amorphous silicon). Consequently, batteries of mobile devices equipped with IGZO displays go longer between charges.
The report says that in tandem with advances in IGZO technology, Apple has decided to expand its adoption of IGZO displays to the iPad and to introduce IGZO displays to the upcoming MacBook, slated for release in the first half of next year, with Sharp ramping upe production of IGZO panels, and LG Display upgrading its AM OLED and LCD production lines to make them capable of IGZO panel production.
