Leaked Photo of an iPad 3 Retina Display?
Top: iPad 2, Bottom: iPad 3?
We believe the top image represents the current iPad 2 screen, while the bottom image is the supposed iPad 3 display. Both are 9.7" in diagonal, but the bottom screen has a different configuration for the attached cabling.
For reference, iFixit provided us with this photo of what the current iPad 2 display looks like disassembled.

As you can see there are 3 brown ribbon cables leading from the screen itself to the circuit board. The small brown cable to the far left is the power cable, while the other two wide cables are for display data. This configuration matches with the top display in the leaked photo (though the power cable is missing).
The claimed iPad 3 photo shows 3 wide ribbon cables that might be used for data. The iPad 3 is expected to carry a high resolution screen of 2048x1536 which is four times the number of pixels of the current iPad 2, so the need for additional data bandwidth would be understandable.
No other details are available, though the increasing number of parts leaking on the web suggests that Apple is getting closer to production. Just last night, Apple was said to be using a new type of display (IGZO) to achieve higher resolutions and require lower power in the iPad 3. The iPad 3 is expected to be launched during the first half of 2012.
