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 driver comprising: a gray-scale bus to which gray-scale data is supplied; a capture start timing setting register in which is set data to set a capture start timing of the gray-scale data, the capture start timing of the gray-scale data being based on a signal indicating a supply start timing of the gray-scale data; a capture instruction signal generation circuit which generates a first capture instruction signal and a second capture instruction signal, the first capture instruction signal and the second capture instruction signal being generated by delaying the signal indicating a 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 outputs first data to a first group among the plurality of data lines, the first data being based on the gray-scale data captured in the first data latch; and a second driver circuit which outputs second data to a second group among the plurality of data lines, the second data being based on the gray-scale data captured in the second data latch.
