Abstract
An interface circuit generates a timing signal indicating the timing at which to switch between a data input period and a non-input period, and outputs a second start pulse signal obtained by delaying a first start pulse signal. Anomaly detection circuits detect an anomaly that has occurred in source drivers, and a detection result selection circuit selects one of the anomaly detection circuits during the non-input period and outputs a detection result signal indicating detection results. A selector selectively outputs the second start pulse signal or the detection result signal on the basis of the timing signal.
