DigiTimes claimed on Friday that Apple was making the revisions to reduce the heat output of the iPad.
"The extra LED is reportedly adding to overheating and that using one LED will help solve overheating issues since more backlights along with more power to heat those backlights is causing overheating," the report read.
The publication's sources said that switching back to the one LED module would not affect "luminosity and clarity" of the iPad display.
Separate reports also out of the Far East have claimed that Apple will include IGZO technology from Sharp in the next iPad. The iPad maker was rumored to go with an IGZO display for its third-generation tablet, but Sharp was reportedly unable to produce sufficient volumes in time. IGZO displays are expected to allow for a thinner design with better battery life.
DigiTimes claimed on Thursday that Apple would release an iPad with "small revisions" before the end of the year. The earlier report suggested that Apple would change the battery to avoid overheating problems and also enlarge the lens hole on the device.
Shortly after Apple's latest iPad was released, some reviews claimed the device ran noticeably hotter than its predecessor. Apple, however, insisted that the tablet was operating "well within" its thermal specifications.
