iFixit Takes a Closer Look at the 'iPad 3 Retina Display'
iFixit's comparison of iPad 2 and iPad 3 display pixels
We've since shared the display with our friends at iFixit to see if they could power the screen and otherwise take a closer look at it. Unfortunately, with the different connector on the new display, iFixit was unable to directly hook the display up to the guts of an iPad 2. Meanwhile, efforts to map the pins of the two displays in an attempt to jury-rig the iPad 3 display were believed to be too substantial to undertake with the limited time and no guarantees of success. iFixit was, however, able to confirm our findings of an ultra-high resolution display that quadruples the number of pixels over the previous-generation iPads.
In this new video overview of the iPad 3 display, iFixit confirms the higher (2048x1536) resolution, the modified connector, and tweaked retaining clips as compared to the iPad 2 display.

Apple is expected to introduce the iPad 3 with a media event on March 7. Beyond the display, photos of a number of claimed parts for the device, including the logic board and front glass/digitizer, have leaked in recent weeks, offering some reasonable evidence of what can be expected in the updated models.
