ABSTRACT:
An active flat-design video screen is described, having signal line means arranged in lines and columns, these signal line means, at their crossing points, defining picture elements of the video screen, in which case the lines that are arranged in columns are developed as electrodes and the signal line means that are arranged in lines are developed by means of optical waveguides into which, on the input side, a modulated light signal is coupled and which, at each crossing point, have a device for the coupling-out of the respective light signal. In comparison to conventional active flat-design video screens, the video screen according to the invention distinguishes itself particularly by a good picture resolution and a good contrast range, connected with a good regeneration rate.
