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: first and second divided gray-scale buses; a gray-scale bus to which gray-scale data is supplied corresponding to an arrangement order of each of the data lines; a gray-scale data distribution circuit which distributes and outputs the gray-scale data supplied to the gray-scale bus to the first and second divided gray-scale buses; a first driver circuit which drives the data lines belonging to a first group among the data lines based on the gray-scale data output to the first divided gray-scale bus by the gray-scale data distribution circuit; and a second driver circuit which drives the data lines belonging to a second group among the data lines based on the gray-scale data output to the second divided gray-scale bus by the gray-scale data distribution circuit, wherein the gray-scale data distribution circuit alternately outputs the gray-scale data supplied to the gray-scale bus to the first and second divided gray-scale buses in units of the gray-scale data for the predetermined number of data lines.
