Microsoft is trying for a patent that would automatically disinfect grimy touchscreens



From Engadget:

The method would send ultraviolet light bouncing through a film on or inside a touchscreen, disinfecting fingertips and contact areas without blasting the person directly. Processing inside the gadget could also dictate just when and for how long the UV blast would run. It could kick in only after a user was done, for example, and last just long enough to kill common germs.
