that is expected to be launched towards the end of March or April.
MacRumors have found new graphics in iBooks application with higher resolution labelled “iPadx2”, which indicates that iPad 2 may come with a display that has twice the resolution in both directions (2048×1536) of the current iPad (1024×768). This means that iPad 2 may come with a 2048×1536 screen resolution at 260 DPI compared to current iPad’s 1024×768 screen resolution at 132 DPI.
Based on Apple ‘s marketing efforts for the original “Retina” display, it would suggest a DPI (dots per inch) greater than 300 to exceed the abilities of the human eye.
A more practical approach would simply be doubling the resolution of the current iPad (1024×768) to 2048×1536 at a 260 DPI. While not quite a “Retina” display, it would follow with Apple ‘s efforts to avoid fragmenting their product line. From a developer’s perspective, the doubling of an existing resolution is much easier to support. Apple similarly doubled the iPhone ‘s resolution from 480×320 to 960×640 when they introduced the iPhone 4. Like on the iPhone 4, older apps can will simply run pixel-doubled while native apps will take advantage of the full resolution of the new screens.
The “Retina” definition is based on a specific distance the device is being held from your eye. Since an iPad display would likely be held farther from your face, it would require a lower DPI to achieve the same effect.
(to be dubbed the Apple A5) instead of the current Apple A4 processor, which is a single-core Cortex A8 processor..
