Sony released a video of their new flexible thin film display. The display is thin enough to bend like paper and displays full color images. The display is created using a combination of 'thin film transistor' and 'organic electroluminescent display' (OLED) technologies. At the moment Sony is not 100% certain what future applications to which the technology will be applied. However, I think that their wallpaper idea may have some wings. How great would it be to be able to repaint a whole room just by flicking a switch? Or even better, change the color based on the time of day?
