Abstract
A microdot trichromatic fluorescent screen comprising two facing substrates. The first substrate supports cathode conductors provided with microdots, grids and an insulating layer separating the same. The second substrate supports three series of parallel conductive bands. The conductive bands of each series are electrically interconnected and covered with a material luminescing in one of the three primary colors red, green and blue. Each series of conductive bands corresponds to a red, green or blue anode. The production of this screen requires no positioning between the two substrates.
