The display panel that you see in the picture above might be the much rumored retina display for the Apple iPad 3. There seems to be a change in the cable ribbon arrangement to support higher powered displays.
The picture below shows the comparison between the iPad 2 and supposed iPad 3 displays with the iPad 2 display being on the top.
The iPad 2 screen had two wide brown ribbon cables while the retina screen seems to have 3 brown ribbon cables for data. This would help to power the new display which supports a resolution on 2048×1536 pixels which means its four times the resolution of the previous generation iPads.
