Use of Transparent Photosensor Array to Implement Integrated Combinations of Touch Screen Tactile, Touch Gesture Sensor, Color Image Display, Hand-Image Gesture Sensor, Document Scanner, Secure Optical Data Exchange, and Fingerprint Processing Capabilities

摘要

A system and method for implementing a display with a photosensor overlay, permitting the arrangement to also serve as one or more of a proximate hand gesture sensor, light field sensor, lensless imaging camera, document scanner, fingerprint scanner, and secure optical communications interface. The resulting arrangements are accordingly advantageous for use in handheld devices such as cellphone, smartphones, PDAs, tablet computers, and other such devices.
