Display driver and electro-optical device

摘要

A comb-tooth drive is realized by using 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 each of the data lines; first and second clock lines to which first and second shift clocks are supplied; first and second shift registers which shift first and second shift start signals in first and second shift directions based on the first and second shift clocks, respectively; first and second data latches which latch the gray-scale data based on the shift outputs of the first and second shift registers, respectively; and a data line driver circuit which drives the data lines based on the data latched by the first and second data latches.
