LCD Screen With Embedded Optical Sensors 113
dk3nn3dy writes "Sharp has developed a LCD display with optical sensors built into the displays pixels, without requiring a touch-sensitive film to be bonded on top of the regular screen. The optical sensor is similar to that used in scanners, allowing for notes or business cards to be scanned by the screen itself. As the optical recognition technology is built into the pixels it also simplifies tactile recognition based on simultaneously touching multiple points. Future uses include fingerprint authentication on the screen of your mobile phone or PDA, or iPhone style touch recognition. Volume production will start next spring."

No it couldn't, any more than a blank sheet of photographic paper could produce an image (all by itself). Simply put: unless there is a lens, or a pinhole (Google for things like "pinhole camera"), or as someone mentioned, each detector element has a drastically limited field of view, like a dragonfly eye, you won't get an image. Each element in this case just collects the light that hits it. Just like a proximity scanner.
If you project an image, using an external lens, then you'll get a picture. Otherwise not.
