Abstract: Disclosed herein is an apparatus and method for detecting a fault in a digitizer. The apparatus includes a function generator for generating test signals, a transmitting switch for transmitting the test signals generated by the function generator to a selective part or all of X- and Y-channels of a transmitting digitizer, a receiving digitizer arranged in a shape identical to that of the transmitting digitizer to be adjacent to the transmitting digitizer, the receiving digitizer receiving reception signals produced by the transmitting digitizer, a receiving switch for receiving resulting signals, generated by the receiving digitizer in response to the reception signals, from a selective part or all of X- and Y-channels of the receiving digitizer, a channel controller for controlling the transmitting switch and the receiving switch, a data collection unit for collecting the resulting signals, and an analysis unit for analyzing the collected resulting signals.
