LG Display and Samsung are facing a tough challenge, sources in the manufacturing industry have reported - making a high-resolution display for the iPad 3.
Cnet reports that Apple is aiming for a much higher resolution of 2048 x 1536 pixels on the next-generation iPad, four times the current 1024 x 768 resolution of the first- and second-generation models.
This will give the iPad 3 a 264 ppi (pixels per inch) display, close to the iPhone 4 and iPhone 4S' 'retina' display of 960 x 640, which works out to 326 ppi.
However, an insider told Cnet that LG Display and Samsung haven't begun manufacturing the displays yet - that'll happen some time in November - and that producing them in volume is likely to prove very challenging.
"It's not a question of making just one. That, of course, can be done. The challenge is making lots of them," the source told Cnet. "This is a quantum leap in pixel density. This hasn't been done before."
However, the source didn't go into any further detail about the specifics of producing high-resolution displays in volume.
Samsung recently showed off a 2560 x 1600 pixel LCD panel for a 10.1in tablet, which it is thought could eventually make its way into Samsung's Galaxy Tab range.
