Abstract:
1. A data driver which drives a plurality of data lines of an electro-optical device which includes a plurality of scan lines, the data lines and a plurality of pixels, the data lines being comb-tooth distributed in units of a predetermined number of the data lines, the data driver comprising: a gray-scale bus to which gray-scale data is supplied corresponding to an arrangement order of each of the data lines; a capture start timing setting register in which is set data for setting capture start timing of the gray-scale data based on a signal which indicates supply start timing of the gray-scale data; a capture instruction signal generation circuit which generates first and second capture instruction signals which are delayed in relation to the signal which indicates the supply start timing of the gray-scale data for a period corresponding to the data set in the capture start timing setting register; a first data latch which captures the gray-scale data on the gray-scale bus at capture timing based on the first capture instruction signal; a second data latch which captures the gray-scale data on the gray-scale bus at capture timing based on the second capture instruction signal; a first driver circuit which drives a data line belonging to a first group among the plurality of data lines based on the gray-scale data captured in the first data latch; and a second driver circuit which drives a data line belonging to a second group among the plurality of data lines based on the gray-scale data captured in the second data latch.
