Patent ID: 11798509

Abstract:
A display driver drives a display device including a plurality of data lines and a demultiplexer. The demultiplexer includes a plurality of first switches connected to the respective plurality of data lines, and a series of driving voltages including a plurality of driving voltages is supplied via a first wiring. The demultiplexer supplies the plurality of driving voltages to the respective plurality of data lines via the plurality of first switches. The display driver includes: a voltage multiplexing part that generates the series of driving voltages; a second switch connected between the voltage multiplexing part and the first wiring; and a controller connected to the plurality of first switches and the second switch. The controller switches the second switch from an on state to an off state during a first period and sets the two first switches corresponding to the two data lines to the on state such that the two data lines and the first wiring are connected during a second period that is a part of the first period and in which the second switch is in the off state.
