Display driver

Abstract

A display driver is configured to drive a display device according to a video signal. The display signal includes a plurality of first to N-th output amplifiers (N is an integer greater than two) and an output electrical current capacity setting portion. The first to N-th output amplifiers are configured to amplify first to N-th gradation voltages a representing brightness level per pixel according to the video signal, so that the first to N-th output amplifiers obtain first to N-th pixel drive voltages. Further, the first to N-th output amplifiers are configured to output the first to N-th pixel drive voltages to the display device. The output electrical current capacity setting portion is configured to set an output electrical current capacity of each of the first to N-th output amplifiers individually or in a group of a plurality of output amplifiers.
