iPad 3's resolution display

iPad-3's resolution display will be a most remarkable feature among the Apple products. Apple wants it to be Retina Display-like resolution.
Retina Display-like resolution refers to a diaplay in which "pixel density is so high your eye is unable to distinguish individual pixels."
iPad-3's resolution of 264 pixels per inch (PPI) display is going to be a challenge for the manufacturers.

The closest that iPad display manufacturers like LG Display and Samsung can get is 2048×1536 resolution display, according to the source. That’s a PPI of 264, twice the 132 PPI on the iPad 2. But whether manufacturers can make them in volumes that Apple demands is the question. “They have production plans for 2,048×1,536 displays. Starting in November. But those are only plans at this point,” said the source, referring to LG and Samsung. “It’s not a question of making just one. That, of course, can be done. The challenge is making lots of them,” the source said. “This is a quantum leap in pixel density. This hasn’t been done before.” If manufacturers are not able to hit the volumes necessary for the higher resolution, there is an interim option of 1,600×1,200, according to the source. The display is also expected to have a brightness of 550 nits. That’s pretty bright, as the typical laptop display panel tops out at about 350 nits.
