Abstract
The present disclosure may provide a display apparatus including a display panel configured to display an image, a shift register configured to supply a scan signal to the display panel, a level shifter configured to output clock signals for driving the shift register, a power supply configured to supply a gate voltage to the level shifter, and a controller configured to sense a node voltage of a circuit generating the gate voltage, detect a short circuit between the clock signals based on a sensed value and an internal reference value, and control the power supply when the short circuit occurs between the clock signals.
