News from DigiTimes states that sources believe that Apple is going to replace their IPS displays with those using IGZO technology. This new material, IGZO – Indium, Gallium, Zinc, Oxygen, replaces the traditional amorphous silicon based active layer. IGZO has an electron mobility 40 times greater than traditional materials such that a display’s reaction speed can be more swiftly controlled. In doing so, panel makers will be able to offer screen resolutions higher than the current Full High Definition.
Some analysts think that Sharp and Apple will develop IGZO based OLED Displays in the next 1-2 years. Large OLED panels with IGZO are expected in 2014-2015.
What’s interesting is that this technology is already being prototyped for use in HDTVs. The 32″ unit noted above was produced by AU Optronics (AUO) Corp and shown at a tradeshow held in Yokohama, Japan in late October 2011.
It would be a natural technical and marketing move for Apple to begin producing IGZO displays for their iOS devices and then enter the HDTV market using the same material. Apple’s driven volumes for iOS devices using IGZO would help Apple bring the costs down for their future HDTVs. It would also play very well in a future iMac scenario – sleek and thin screens.
