DESCRIPTIVE . Microdot trichromatic fluorescent screen constituted by two facing substrates (10,22). The first substrate (10) supports cathode conductors (12) provided with microdots (14), grids (16) and an insulating layer (18) separating the same. The second substrate (22) supports three series of parallel conductive bands (26). The conductive bands (26) of each series are electrically interconnected and covered with a material (28,29,30) luminescing in one of the three primary colours red, green and blue. Each series of conductive bands (26) corresponds to a red, green or blue anode (A1, A2, A3). During its production, this screen requires no positioning between the two substrates (10,22). Application to the display of fixed or moving pictures. (Fig. 3) B 9678.3 PM |
