Apple has been testing retina screens for the iPad 3 tablet since last year, but at the moment their implementation in a tablet depends only on Samsung and LG. The Retina Display for iPad 3 would have a resolution of 2048×1536 and 264 pixels per inch, Apple practically doubling both the resolution and the pixel density. Now Apple has such screens in tests on tablets, but the problem is that Samsung and LG do not have a sufficiently efficient manufacturing system to allow them to produce such screens in very large quantities.
The closest that iPad display manufacturers like LG Display and Samsung can get is a 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 the 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.
Those from cNET supports that the production for these screens should start in November of this year, but for now everything is at a theoretical level because Samsung and LG do not have a manufacturing process set up. What is interesting about these screens is the fact that they have a brightness of 550 nits compared to 350 as a laptop, so we are talking about major improvements from this point of view as well. Those from cNET say that the screens designed by Apple use a technological process used for the first time in this kind of product and this is basically the problem.
It would not be excluded to see Retina Display in iPad 3, but it would not be excluded that Apple continues with the same screens and the same resolution.
