After months of rumors and speculations, it has been finally confirmed that iPad 3 will feature retina based display panels according to the guys at Macrumors who had the privilege to get their hands on the iPAd 3 display panels that has been circulating in China for a while.
As you can see from the image below, the microscope study of the panels suggests that iPad 3 display will have 4×4 pixels as opposed to the 2×2 pixels that existed in the iPad 2′s display panels.
MacRumors reports :-
Since we only had a raw iPad 3 display with no method to power it, taking high quality photos of the pixels was difficult. Still, even with the relatively poor lighting, you can easily make out the pixels on each display (made up of red, green and blue elements). We highlighted a cluster of 4 pixels (2×2) from the iPad 2 to compare it to the same area on the iPad 3. On the iPad 3, the same cluster was occupied by 16 pixels (4×4) — exactly twice the resolution in each direction.
Extrapolating out, the iPad 3 screen should carry a full resolution of 2048×1536, exactly twice the linear resolution of the iPad 1 and iPad 2 which is 1024×768. Such a screen should be able to display much sharper images as compared to the previous generation iPads.
Apple will introduce iPad 3 at the media event on March 7th which is not much far from now and every ambiguity will be cleared then.
