Based on a new DigiTimes report, Apple is evaluating the feasibility of using IGZO displays across their new iPad, iPad mini, and iPhone product lineups in 2013. The report mentioned the following regarding the topic:
The sources said Apple is in further discussions with Sharp over IGZO panel production capacity estimates for 2013 and is also inquiring about whether AU Optronics' (AUO) L5C line could be used to produce the technology.
The IGZO displays supposedly have many benefits over existing technology. The folks over at PCWorld note lower power consumption, improved touch sensitivity and increased pixel density as some of the benefits. The following was said about the displays:
This difference in current flow inside the screen also means that transistors don't have to be continually refreshed when a still image is on the screen. That leads to lower power consumption and, for touch panels, much less interference from the screen's electronics so the touch panel becomes more accurate and sensitive, said Nobuhiro Okan, a manager with Sharp's display device group.
Whether or not IGZO displays make it to the next generation iOS product lineup, the only way we’ll find out is by being patient.
