Ultra thin bright-light emitting device pave way for ‘invisible’ displays

Researchers at UC Berkeley have developed what they claim is just millimeters wide bright-light emitting device capable of paving way for ‘invisible’ displays. These emitting devices become fully transparent when turned off. The light emitting material in this device is a monolayer semiconductor, which is just three atoms thick. The device opens the door to invisible displays on walls and windows – displays that would be bright when turned on but see-through when turned off — or in futuristic applications such as light-emitting tattoos, according to the researchers. The device was developed in the laboratory of Ali Javey, professor of Electrical Engineering and Computer …
