[Excerpt]

Apple’s 3D approach will not be a trick on your eyes, but an actual physical effect that is delivered via three individual displays that are stacked on top of each other.

A recently published patent filing reveals that Apple envisions two transparent OLEDs as well as a background LCD to be used for a 3D display that can deliver limited depth by separating content. At least one processor will be used to control the separation and the interaction of content, while the patent describes a scenario in which one GPU is controlling all displays and another in which individual GPUs are tied to individual displays.

The desired effect is more depth to elements on a screen. Apple notes that such 3D display devices can include everything from desktop displays to portable devices, which we imagine could also include the iPad. … With this patent application we think a 3D iPad is entirely possible, especially since this patent was filed already back in January of 2010.
