Abstract
An image contained in an incident signal is displayed on a screen forming part of a matrix-access display device. The device is primarily applicable to high-definition or small-area screens designed for operation in the transmission mode, and is controlled by an optical system. Optical addressing of a line array and a column array of electrodes is performed by means of light beams which serve to illuminate photodetectors.
