Abstract
Active matrix display screen and processes for producing it. Each block (51) is associated with a conductive strip (55) connecting the drain of the control transistor (61) to the addressing column. The addressing line is narrower at the intersection of a column than in the zone of the transistor and the isolation of the intersection can be different from the isolation of the gate.
Claims5
Active matrix display screen comprising a first plate (10) coated with a matrix of conductive blocks (22), thin-film transistors (20), a plurality of conductive addressing lines (14) and a plurality of conductive addressing columns (12), each transistor (20) having a gate connected to an addressing line, a source formed by a projection connected to one of said blocks and a drain connected to a column, said screen further having a second plate (24) comprising a counterelectrode (26) and an electrooptical material inserted between the two plates, said screen being characterized by the fact that each draincolumn connection is made by a strip (55) of conductive material exhibiting a certain resistance, the drain of each transistor being formed by the part of the strip located in the zone where an addressing line overlaps said strip and wherein each addressing line has a certain width in the zone where the transistors are formed and another width smaller than the first, in the zone where said strip intersects an addressing column.
