Patent abstract
A display driver according to the present invention includes a withstand voltage protection part that precharges an output node of a polarity changeover switch circuit that switches a polarity of a drive signal supplied to a display device from an electric potential of a positive polarity (a first electric potential to a third electric potential) to an electric potential of a negative polarity (the third electric potential to a second electric potential) or vice versa to the third electric potential immediately before the polarity switching.
