Abstract
A power provider includes: a first power converter to convert an input voltage, and output a first power voltage to a display panel through a first power line; a second power converter 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 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 during a short circuit detecting period. The short circuit detecting circuit is to vary a length of the short circuit detecting period and the reference short circuit voltage level in response to a driving frequency.
