Microsoft Patents Self-Sterilizing Touch Screen

News
By published

Microsoft filed a patent that would provide a solution for those who are concerned about all the germs populating a touch screen surface. Microsoft uses ultraviolet light to sterilize the surface of a screen.

It is widely known that devices such as keyboards and computer mice are the least hygienic places in any household. As we are replacing keyboards with touch screens, those greasy screen surfaces could become prominent transfer stations for bacteria. A patent filed by Microsoft in April 2010 suggests that an ultraviolet (UV) light source could be used to sanitize touch screen surfaces. The UV light source would be integrated into a device and would be positioned with the backlight and kill germs from the rear side of the touch screen.

The patent envisions the technology to be used not only for personal computing devices, but especially devices that are exposed to different people, such as ATM screens at banks, checkout stations in grocery stores as well as kiosks at airports. The technology is designed to be used in combination with a proximity sensor that activates the UV light source when a user is not present - and emit UV light at a wavelength that is suited to sterilize the touch screen.

There was no information in which specific products the technology could become available.

    Reassuring for germaphobes. I is also nice to be clean for normal people. Although I ma not really concern about it.

    Now you can steal password even easier. Just need fluorescence powder on the fingers because UV light is already there.

    Some cellphones have a antibacterial coating and it also kill off germs.
    Microsoft can invent something that cleans off finger prints too.
