According to DigiTimes, Apple might be planning to return to one backlight for the third-generation iPad, as opposed to the two-LED system. The two-LED backlighting system is said to be the cause of the overheating problems that people have been complaining about. The heat is said to be coming from the extra light, as well as the extra power needed to run them.
Returning back to one LED backlight will reportedly not affect luminosity and clarity of Apple’s Retina display.
Apple is also said to be working on improving the latest iPad’s battery, which will also help with the problems of overheating. With these battery and LED changes, the latest iPad will be similar in weight and thickness to Apple’s second-generation iPad, DigiTimes‘s sources say.
Chinese-language Apple Daily added that an upgraded iPad could also feature indium gallium zinc oxide (IGZO) panel technology that would allow a thinner iPad design and longer battery life and that the panel supply would shift from Samsung to Sharp.
DigiTimes speculated that a modified version of the latest iPad could start shipping around the holiday season.
