Abstract

See full text

Disclosed is a display device which includes a voltage generator including a first converter that generates a first voltage using an input voltage and is shut down in response to a shutdown signal and a short circuit protection part including a first short circuit protection part that compares an output voltage of an output terminal of the first converter with a first reference voltage and outputs the shutdown signal. The first converter pre-charges the output voltage to a predetermined voltage level during a first period, maintains a level of the output voltage during a second period subsequent to the first period, and boosts and outputs the output voltage as the first voltage during a third period subsequent to the second period. The first short circuit protection part outputs the shutdown signal when the output voltage in the second period has a level lower than that of the first reference voltage.
