In principle nothing, but Avatar used the common sci-fi trope of see-through displays. Bleah. To see why this is a bad idea, take a page of text - any text - and print out one copy on a standard sheet of paper, and print out another on a transparency (amazingly, they still sell that stuff). Then hold said sheets of text up to a TV screen thats showing people walking around and doing stuff (or, better yet, scenes of flying through valleys at high speed), and then try to read them.
