Abstract

A method of manufacturing a cathode ray tube for displaying color images, in which a photosensitive layer is placed on a support for the tube image display, a mask is placed comprising a tracing or design of light transmitting regions to A small distance in front of the photosensitive layer, the mask is scanned using a thin ray of light to form a path of exposed and unexposed regions on the photosensitive layer, and the photosensitive layer is then revealed, characterized by the fact that the explorer light beam splits of a point that moves during scanning in a predetermined way that is related to the direction of the scanning light beam.
