A supply chain leak has revealed that Taiwan-based Radiant Opto-Electronics has become the major supplier of backlight units for its forthcoming iPad 3. Apple has appointed LG Display, Samsung and Sharp to supply the rumored high-resolution LCD panels for its next-gen iPad, with LG producing the majority of the display units. All three companies are getting their backlight components from Radiant, either for all or most of their LCD panels, giving the company a major role in the next iPad.
