Classification: CPC G | IPC G

Claim 0:
1. A power provider comprising:
a first power converter configured to convert an input voltage, and output a first power voltage to a display panel through a first power line;
a second power converter configured to convert the input voltage, and output a second power voltage to the display panel through a second power line; and
a short circuit detecting circuit configured to detect a short-circuit of the first power line and the second power line in the display panel, by determining whether or not a level of a sensed voltage measured at the second power line is greater than or equal to a reference short circuit voltage level in response to a sensing enable signal output during a short circuit detecting period,
wherein the short circuit detecting circuit is configured to vary a length of the short circuit detecting period and the reference short circuit voltage level in response to a driving frequency, and
wherein the short circuit detecting circuit is configured to delay the output of the sensing enable signal based on a first pre-charge end signal.
