GM Patents Fingerprint Erasing Touchscreen Displays

Touchscreens are slowly taking over our lives, but the demise of buttons doesn’t mean you’ll have to give up french fries or other greasy foods. General Motors has patented a new system for in-car touchscreens that can make greasy smears and fingerprints disappear overnight. It uses special coatings and built-in UV lights that cause the organic materials on the surface of the screens to break down until they’re gone.
