Display Driver And Display Apparatus

Abstract

A display driver includes a driver circuit that outputs a drive signal, an output terminal that outputs the drive signal to a display electrode of an electro-optical panel, an input terminal to which a monitor signal is input from the display electrode, and an inspection circuit. The inspection circuit includes a comparison circuit that compares a voltage of the monitor signal with a reference voltage, a determination circuit that determines an abnormality based on an expected value corresponding to a voltage level of the drive signal and a comparison result of the comparison circuit, and a potential setting circuit that pulls down or pulls up a signal line of the monitor signal according to the voltage level of the drive signal.
