Abstract
A sensor-display device comprises an array of transmit-receive modules, each of which comprises a light transmitter, a light receiver, and a memory bank. A modulation driver connected to the light transmitter drives the light transmitter to transmit light. The light receiver creates electric charges from light received by the light receiver. A memory interface connects the light receiver to the memory bank for shifting the electric charges as data from the light receiver into the memory bank, and the memory interface shifts the data as electric charges from the memory bank to the modulation driver to drive the light emitter to transmit light based on the electric charges.
