Abstract
A comb-tooth drive is realized by a display driver which drives data lines. The display driver includes a gray-scale bus to which gray-scale data is supplied corresponding to an arrangement order of the data lines, first and second bidirectional shift registers of which the shift directions are determined based on first and second shift direction control signals and which shift first and second shift start signals based on first and second shift clock signals, first and second data latches which latch the gray-scale data based on shift outputs, and a data line driver circuit which drives the data lines based on the latch data.
