Patent ID: 7154488

Claim:
A driver circuit for driving an electro-optical device, wherein the electro-optical device comprises: a plurality of scanning lines; a plurality of signal lines, each of the signal lines transmitting a multiplexed data signal for first to third color components; a plurality of pixels, each of the pixels being connected with one of the scanning lines and one of the signal lines; and a plurality of demultiplexers, each of the demultiplexers including first to third demultiplex switching elements which are respectively switch-controlled based on first to third demultiplex control signals, one end of each of the first to third demultiplex switching elements being connected with one of the signal lines and the other end of each of the first to third demultiplex switching elements being connected with one of the pixels for a j-th color component (1≦j≦3, j is an integer), wherein the driver circuit comprises a gate signal generation circuit which outputs a gate signal to each of the scanning lines, the gate signal corresponding to shift output obtained by shifting a start pulse signal, and wherein the gate signal generation circuit comprises a start pulse signal generation circuit which generates the start pulse signal on condition that at least two of the first to third demultiplex control signals go active at the same time.
