they are on the first steps in that direction
i think we are going to see full screen display phone with nokia
there is an interview with Richard Kerris here is a part of what he said
"Nokia has a ton of investment in R&D and is turning concepts in to reality with bendable screens and a complete wrap around display so that when you want your device to be a camera, it looks like a camera. With bendable screens, you flex the display to zoom in or out, depending on the angle.
In addition, they are also working on making devices become aware of where they are. For example, when you walk in to your house after work, it hides all of your business emails and content or when a child picks of the device, it can detect the small hands and lock settings and email accounts"
