The iPad 3, Apple Inc.'s next-generation tablet computer, will have a high-resolution "Retina" display that promises to double that of the current iPad 2.

Enthusiast site MacRumors said one such display it managed to obtain is physically the same size as those of the iPad 1 and iPad 2 9.7 inches diagonal.

"However, when comparing the iPad 3 display to one from an iPad 2 under a microscope, the difference in resolutions becomes readily apparent, with the iPad 3 display's pixels appearing to be one-quarter the size of those on the iPad 2," it said.

When it highlighted a cluster of four pixels (2x2) from the iPad 2 to compare it to the same area on the iPad 3, the same cluster on the iPad 3 had 16 pixels (4x4), or twice the resolution in each direction.

MacRumors said this would mean the iPad 3 screen should carry a full resolution of 2048 x 1536, exactly twice the 1024 x 768 linear resolution of the iPad 1 and iPad 2.

"Such a screen should be able to display much sharper images as compared to the previous generation iPads," MacRumors said.

MacRumors said Apple is expected to introduce the iPad 3 with a media event on March 7, and the device is rumored to be carrying this high-resolution display.

The iPad 3 is also expected to have a new A6 system-on-a-chip, and LTE support for models with cellular data capabilities. — LBG
