New iPad 3 overheating issues down to LED backlight?

Apple’s new iPad 3’s overheating issues could be being caused by the device’s LED backlight, claims an expert on the subject

Overheating issues on the new iPad 3 are apparently related to the device’s new LED backlight, according to one expert.

Speaking to CNET, Raymond Soneira, president of DisplayMate Technologies, said: ‘The LED power at maximum brightness is 2.5 times that of the iPad 2. They had to jack up the number of LEDs so the peak brightness is the same as on the iPad 2. That absolutely makes it warmer.’

Many reports have linked the new iPad’s heat issues to its 4G wireless radio, its A5X CPU or its new quad-core GPU. Soneira, however, is convinced it is to do with the iPad 3’s Retina Display, citing a trio of additional possible scenarios that could cause the device to overheat, all of which relate back to the Retina Display.

The first is that the device uses twice the number of LEDs as the iPad 2. The second relates to the battery and the additional strain that’s put on it by the Retina Display. The third, according to CNET, is that Sharp's power-efficient IGZO technology was not ready for the new iPad, which forced Apple into using a traditional and less power efficient amorphous silicon display technology.

We haven’t experienced any ‘overheating’ issues with our new iPad 3. Battery life is no way near as good on the new device, but that's a small price to pay for that gorgeous 9.7-inch Retina Display.
