Industry sources tell DigiTimes that Apple will be making revisions to the next iPad's backlight module by reverting back to a single LED structure in an effort to eliminate overheating issues. The new iPad that is being designed for Q4 will also sport Sharp's new indium gallium zinc oxide (IGZO) panel technology to allow the device to feature an even thinner design and longer battery life. DigiTimes sources also stress that the changes will not affect the luminosity or clarity of the Retina Display.
