1. An input sensor short-circuit inspection method comprising:
setting an inspection frequency for detecting a short-circuit of an input sensor comprising a plurality of electrodes;
driving the input sensor in an inspection mode at the set inspection frequency; and
detecting the short-circuit of the input sensor based on a capacitance charged between adjacent electrodes among the plurality of electrodes of the input sensor in the inspection mode.
