No matter how hard you try to prevent it, you end up with fingerprints and smudges all over the touchscreen in your car.
Now, to make these fingerprints less annoying, General Motors has developed a fascinating self-cleaning technology to clean up the annoying fingerprints over touchscreens. Not just fingerprints, the method will also remove oil, grease, and fast-food residue from the surface of the glass.
Instead of having to wipe clean, the car will activate the self-cleaning technology every night so that you have a super clean display the next morning. However, if your touchscreen gets gross during the day, you can manually activate the cleaning as well.
Instead of just red, green, and blue LEDs at different intensities for the pixel array behind the screen, GM’s design will have a fourth pixel throughout the matrix, specifically tuned to the invisible ultraviolet wavelength.
There will be a fully transparent layer of some metal-oxide-based photocatalyst – possibly titanium dioxide that absorbs certain wavelengths, applied as a coating on the touchscreen surface.
Self-cleaning touchscreens will not only be useful to drivers but will also improve the experience of using a wide variety of products like smartphones, tablets, or any device that has a touchscreen.
