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.
