Sharp’s new multi-touch display with fingerprint scanning
This new touchscreen from Sharp incorporates an optical sensor at EVERY pixel of the display. These photodiodes work together to create a digital image of a fingerprint, and can also provide multitouch control of a device. This paradigm of an array of optical sensors for tactical control could provide cheaper and much more accurate control of devices. In addition, the fact that the screen is also a camera could be extended into much more useful functions than fingerprinting and control alone. Maybe there’s an opportunity to create better imaging from these displays, even to a point where your cell phone is able to take pictures by using the screen as a lens! It would definitely improve conventional webcams, which do not connect the remote users eye-to-eye, due to the screen-focused gaze being away from the camera, which is on or next to the monitor
