Patent ID: 6919874

Claim:
A display device having an active matrix, comprising: a plurality of scanners for selection lines; a plurality of scanners for columns; a supplementary conductive column crossing over the selection lines and capacitively coupled to each of the selection lines in such a way that each corresponding coupling capacitance has a value close to a sum of coupling capacitances formed between a given selection line and columns which said given selection line crosses; and a shift register coupled to said selection lines, said shift register comprising a plurality of cascaded stages, a given stage being responsive to two clock signals, said given stage having an output and an input, said input being coupled to an output of a preceding stage and to an output of a next stage, said given stage including a first semiconductor output device configured to switch the output of said given stage between high and low values of a first clock signal, the first semiconductor device being controlled by a potential of a first node connected: to the output of the preceding stage via a second semiconductor device controlled by the output of the preceding stage, to a negative potential via a third semiconductor device controlled by the output of the next stage, to a second clock signal via a first capacitance, and to the output of the given stage via a second capacitance.
