Patent ID: 7375716

Claim:
A display driver which drives a plurality of data lines of an electro-optical device which includes a plurality of pixels, a plurality of scan lines, and the data lines, the display driver comprising: a gray-scale bus to which gray-scale data is supplied; a capture start timing setting register in which is set a period between a changing time of a given capture start timing instruction signal and a starting time of capturing the gray-scale data; a shift start signal generation circuit which generates a shift start signal based on a setting state of the capture start timing setting register; a shift register which includes a plurality of flip-flops, shifts the shift start signal based on a given shift clock signal, and outputs a shift output from each of the flip-flops; a data latch which includes a plurality of flip-flops, each of which holds the gray-scale data on the gray-scale bus based on the shift output from the shift register; and a data line driver circuit which outputs a data signal corresponding to the gray-scale data held in the data latch to the data lines.
