The Apple rumor mill just keeps grinding along and now we have word of iPad 3/HD prototypes being tested in China using ultra high-resolution 2048×1536 9.7″ LCD displays. The screens in question both come from Korean suppliers, namely Samsung and LG.

Previously, MegaTech News had speculated that double-resolution artwork for iPads found in the iOS 5 beta builds pointed to the possibility of a higher resolution screen of at least 1080p. As it turns out 2048×1536 is exactly double the current iPad 2 screen resolution of 1024×768, which gives the new display 4x more pixels over current production iPads.

This easily exceeds 1080p, and rumor has it that the pixel density is better than 280 dpi so Apple may be preparing to use their trademarked “Retina Display” moniker for the upcoming iPads. The higher resolution seems to be aimed at content creators as Apple is said to be readying more content creation apps specifically for the iPad as well.

It’s also looking more likely that the iPad 3/HD will be using the A6 processor since quadrupling the graphics resolution will require a lot more horsepower under the hood. We can further surmise upgrades for both the front and back facing cameras to bring them both in line with the high resolution display and to get over the “meh” factor of the current camera sensors in the iPad 2.
