iPad RetinaApple have been doing lots of quality tests for the new iPad screen’s and LG, Samsung and Sharo have been picked to make the screens. DigiTimes story from this morning. LG Display will act as the leading supplier, while

“Sharp stands a chance of overtaking the Korea competitor if it is able to run stable supplies of quality panels”.

Apple has apparently been quality-testing iPad 3 displays from Samsung and LG for some time. The company will entrust backlight modules to Taiwan-based Radiant Opto-Electronics, which also provided those units for previous-generation iPads. Radiant will ship their backlight modules to LG Display, Samsung Electronics and Sharp:

Radiant accounts for over half of the backlight units LG Display needs for its iPad 3 panels, while Samsung sources backlight units from the Taiwan maker for all its iPad 3 panels, the sources said. Sharp also uses backlight modules from Radiant for iPad 3 panels, as well as from a Japan-based BLU supplier, the sources added.

The report makes no mention of iPad 3′s resolution. The blogosphere has been calling for four times more pixels compared to the iPad’s 1024-by-768 pixel display. This means an ultra high-resolution 9.7-inch display with a 2048-by-1536 pixel resolution that Apple would want to market as being Retina-capable.
