New iPad : Retina Display Peered, 2,048 by 1,536 pixels & superior colour saturation

Perhaps the biggest improvement on the new iPad compared to the old iPad 2 is the introduction of the new display type, a new Retina Display screen with a resolution of 2,048 by 1,536 pixels (that's nearly 3.2 megapixel), four times the resolution of the old one with the same display resolution

At 264ppi, the pixel density is way lower than on the iPhone 4 which stands at 326 ppi. Apple's explanation is that the new iPad is meant to be held at 15-inch rather than 10-inch for the iPhone 4; that's what it calls Retina Threshold.

Apple showed a visual representation of the sub-pixel structure which consisted of individual rectangular RGB slabs. The company did confirm that the new iPad still uses In Plane Switching LED-backlit and did say that it was based on proprietary inhouse IP.

The new display is also said to have a 44 per cent greater colour saturation compared to the old iPad 2/iPad display. Worth nothing that last year, Dr. Soneira, the president of DisplayMate Technologies, published an interesting piece on the iPad 2 LCD display shootout where he concluded that the iPad 2 performed poorly with reference to the standard Color Gamut as it has a too small color Gamut. As a result, "the iPad 2 produced images that have significantly too little color saturation" said the report.

This article is part of a series where we look at multiple aspects of the new iPad including the processor, the GPU, the screen, the 4G connectivity, the iSight camera, design and battery life. There's also a nifty comparison between the new iPad and the iPad 2.
