Microsoft Corporation (NASDAQ:MSFT) has filed a patent for touchscreens that have the ability to change its shape in order to create keyboards and other objects. Literally the typography of the plastic layer would change based on actions that you do on the touchscreen. This would especially be handy for a device like the Microsoft Surface and it could make tablet computers a lot more high-tech. Here is the abstract that Microsoft used in the patent:
A light-induced shape-memory polymer display screen is provided herein. One example display device includes a display screen having a topography-changing layer including a light-induced shape-memory polymer. The display device further includes an imaging engine configured to project visible light onto the display screen, where the visible light may be modulated at a pixel level to form a display image thereon. The display device further includes a topography-changing engine configured to project agitation light of an ultraviolet band towards the display screen, where the agitation light is modulated at a pixel level to selectively change a topography of the topography-changing layer.
