Sony presented their new OLED (Organic Light Emitting Diodes) display which is only 0.3mm thick and is flexible. You can see how the man presenting it is bending it and how the movie is still visible and still played.
You can really appreciate the potential (i.e.: low power requirements, no back lights, etc.) of OLED display after watching this video. This technology has a million applications, from super-thin TV, to laptops, to other portable devices.
