Apple could revert to one backlight for current-gen iPad

Overheating in tablet blamed on two-LED design

Apple is reverting the third-generation iPad back to a one-LED backlighting setup, as opposed to the two-LED system the tablet introduced, according to industry sources quoted by DigiTimes. The two-LED arrangement is allegedly responsible for the overheating problems people have sometimes complained of. The heat is said to be coming not only from the extra lights but the extra power needed to run them.

Apple is, in fact, claimed to be working on improving the tablet's battery as well. The changes are expected to bring the device in line with the smaller weight and thickness of the iPad 2. Apple is moreover said by the Chinese-language Apple Daily to be switching to a Sharp-made IGZO display panel, improving thinness and battery life even further. Samsung would lose orders in the panel switch.

DigiTimes' sources speculate that a modified iPad could start shipping around the holiday season. The changes wouldn't be unprecedented; Apple recently tweaked the iPad 2 to improve battery life, and made no announcement of the revision.

    There never was a heat problem, right?

    What does this mean for current owners?

    Return mine before thirty days is up? A free swap? I haven't noticed any heat issues with mine. Had nearly a month, heavy use.

    Simple solution

    For new iPad (iPad 3) owners, simply don't turn up the brightness. I rarely exceed 50% intensity (brightness, so yes, one LED is probably enough) therefore less light per LED, generally meaning less current is pushed through the LED, generally meaning greater efficacy (light per unit electrical power consumed), which all taken together means never having a hot lap or palm! At its extreme operating conditions (e.g., poolside on a sunny day reading the web or a book) is likely the operating scenario for those claiming 'overheating.'

    DigiTimes = not true

    To say the source of this report has a chequered track record would be to insult weasels, shady characters and fly-by-night operations everywhere. Once in a blue moon they get something right, but when DigiTimes is the source you don't need to take it with a grain of salt, you'll need an entire salt shaker.

    iPad 4 ?

    Could the modifications be part of the new iPad 4 rumored for September?

    I bought a 4G model (Verizon) and even through heavy, _heavy_ use for games and what not it doesn't seem to get warm at all. I don't know what people were complaining about....
