Abstract

Cathode ray tube for the reproduction of color images that has a reproductive screen that comprises at least two luminescent substances that, when excited by electrons, emit light of different colors and are arranged according to a recurring layout of parallel strips, so that two adjacent strips, in their luminescent state, emit light of different colors, characterized by the fact that at least the luminescent strips of the material that makes the most luminous impression on the eye have non-luminescent interruptions, so that the number of interruptions in a strip is at least equal to one tenth of the total number of strips on the screen, the separation between two successive interruptions in a strip being at least three times the width of the strip and the length of an interruption is, maximum equal to twice the width of the strip.
