That reminded me of this Apple patent but it looks like this is done in a different method.

Apple files patent for camera hidden behind display http://appleinsider.com/articles/09/01/08/apple_files_patent...

You would still need a lens to form an image on the screen.

It might be possible to use multiple screens to form a sort-of synthetic lens. Also, there is such a thing as a single-pixel camera (http://dsp.rice.edu/cscamera).

notice flatscreen viewing angles, they don't have isoform radiosity, almost like through a lense.
