Abstract
An interface circuit comprises a timing signal generating unit that generates a timing signal indicating a timing to switch between a data input period and a non-input period, a plurality of driver error detection circuits that detects an error in source drivers, a selector circuit that selects one of the driver error detection circuits in the non-input period and that outputs a driver error detection signal indicating an error detection result, an input error detection circuit that detects an input error of a data signal and outputs an input error detection signal indicating the result, an OR circuit that outputs an OR of the driver error detection signal and the input error detection signal, and a signal output unit connected to an output part of the OR circuit.
