Retina Display Expected in iPad 3 Proving Problematic

"This is a quantum leap in pixel density. This hasn't been done before," a source inside Apple's Asian supply chain declared recently, referring to the new display presumed to feature on the iPad 3.

For months there have been rumours about the 10 inch touchscreen of the next generation iPad, and the Retina Display seems to be a converging point for all the speculation. In Apple's words, the Retina Display is one where the "pixel density is so high your eye is unable to distinguish individual pixels," (from 12 inches).

For iPhone 4S' 3.5-inch display this translates to a resolution of 960x640 pixels, meaning 326 pixels per inch. LG Display and Samsung, Apple's partners for manufacturing the iPad can apparently only get to a 2048x1536 resolution display at present, in terms of PPI that would be 264, which is still double the resolution currently featured in iPad 2.

In addition, the screen brightness is going to leap to 550 nits. Comparatively, a typical laptop display has about 350 nits. CNET reports (opens in new tab) today that the new feature is causing problems in the supply chain that could affect the mass production of the device, according to internal sources.

"It's not a question of making just one. That, of course, can be done. The challenge is making lots of them," the source stated.

Analysts believe the manufacturers will be able to overcome this challenge and deliver an iPad 3 by next spring, some recent reports claim by March.
