Abstract
A display apparatus includes a display panel driven based on a first gate clock and a second gate clock, a clock supply circuit including a first output terminal for an output of the first gate clock and a second output terminal for an output of the second gate clock, supplying the first output terminal with one of a gate high voltage and a gate low voltage as a first test voltage, and supplying the second output terminal with the other of the gate high voltage and the gate low voltage as a second test voltage, for a first time immediately after a system power is applied thereto, a power generator generating the gate high voltage and the gate low voltage and supplying the gate high voltage and the gate low voltage to the clock supply circuit, and an overcurrent detector receiving a flag signal to recognize overcurrent from the power generator to shut down the power generator, when the first output terminal and the second output terminal are short-circuited with each other at the first time interval.
