Now this is pretty cool. Apparently, gadgets that can change their color just by pressing a button are on the horizon for tech geeks everywhere. Yes, that means you can make your handheld any color you want on the go. Can you sense the anticipation?
By utilizing cholesteric liquid crystal display technology, or chLCD, gadgets will be able to change color automatically. These special displays have been modified to wrap around any object--a cell phone in this case.
By using three layers of red, green and blue chLCD, the device can be wrapped in the displays with resin in between each layer. This makes them strong and impervious to breakage. Then, all you do is press a button and a electric current changes the color of the screens. The color stays the same--even when the device is powered off--until you press the button again. Apparently, displays capable of up to 4,000 colors will be made in the future by Kent Displays. It remains to be seen if this tech will be used in next-gen devices, but we don't see why not.
