Retina Display for iPad 3 Currently Under Testing

The retina display is finally coming to the iPad – at least that’s the view of The Korea Times, a Seoul-based newspaper. According to the paper, Apple is actively working with both LG and Samsung to offer a new display with a resolution of 2048×1536, exactly four times as many pixels as the 1024×768 screen featured in the first and second generation iPad. While the pixel density of this new display will not be as high as the density used in the retina display featured in the iPhone 4, as it will ‘only’ offer a resolution of about 260 pixels per inch instead of 326, such a screen would still be an impressive feat of engineering: to put things in perspective, the resolution of the new 9.7-inch screen will be higher than the resolution used in devices such as high definition LCDs and Plasma televisions. The new resolution wasn’t chosen by accident: the new screen will offer exactly twice as many columns and rows of pixels, to help developers adapt their apps for the new screen without difficulty. The exact same technique was used by Apple when it transitioned the iPhone to the retina display. Screens from both LG and Samsung are currently being tested, and should be ready for mass production sometime in the third quarter of this year.
Apple’s upcoming iPad 3 will feature an improved display to support quad extended graphics (QXGA), a display resolution of 2048×1536 pixels with a 4:3 aspect ratio to provide full high definition (HD) viewing experience. […] Apple has traditionally preferred to use the same providers of the same parts for the same device, even as they evolve to different versions.
Note that while Samsung tried to convince Apple to adopt the newer OLED technology for this display, Apple does not seem to be interested yet, and plans to stick to the more traditional IPS technology for now:
A possible letdown for Samsung is that Apple appears to have no interest in using its flat screens based on organic light emitting diodes (OLEDs)
At this stage, it is still unclear whether the screen will be used to build an iPad 2 HD, to be released later this year, or an iPad 3, which should be released during Spring 2012.
