Another DigiTimes report suggests the next-gen iPad may incorporate a once-used one-LED backlight design instead of the two-LED module found in the current tablet. The change is again said to address overheating issues, as the second LED along with the energy required to power it reportedly increases the temperature levels of the devices. According to the publication’s sources from the Far East, switching back to the one-LED concept wouldn’t affect clarity and luminosity of the iPad screen.
Separate reports from Apple’s supply chain have also argued that the fourth-gen iPad will feature IGZO panels made by Sharp. Ahead of the new iPad launch, various publications similarly speculated that the company would equip the tablet with Sharp’s IGZO displays. However, Sharp reportedly failed to meet Apple’s production requirements and wasn’t able to manufacture a sufficient amount of panels on schedule. With IGZO screens, the company is expected to reduce the thickness of the upcoming iPad update as well as improve its battery life.
On Thursday, DigiTimes reported that Apple is currently readying small revisions to the next iPad, with the launch allegedly slated for late 2012. The previous report claimed the company is planning to change the battery to smooth out overheating issues and increase the size of the lens hole on the tablet for unspecified reason.
Shortly after hitting the market, the third-generation iPad was criticized for running noticeably hotter than the previous model. However, Apple insisted that the device was functioning in compliance with its thermal specifications.
