ABSTRACT:
A microdot fluorescent screen having a reduced number of addressing circuits. This screen of N rows (16) is divided into k zones Z.sub.i, each of the N/k rows (16) belonging to N/k families of rows. The k rows (16) of the same family are electrically interconnected. Each zone Z.sub.i also comprises three series of N/k conductive bands (26) each. The bands (26) of a first series are covered by a material (28) luminescing in the red, the bands (26) of a second series are covered by a material (29) luminescing in the green and the bands (26) of a third series are covered by a material (30) luminescing in the blue. Each triplet formed by three bands (26) covered by material luminescing in the red, green and blue is aligned substantially facing a row (16) (grid). The bands (26) of each series in a zone Z.sub.i are electrically interconnected for forming three anodes A.sub.1,i, A.sub.2,i and A.sub.3,i.
