Abstract
A DC-DC converter may include a voltage conversion unit and a short detection unit. The voltage conversion unit may be configured to generate a DC voltage for driving a display panel based on an input voltage. The short detection unit may be configured to generate a driving voltage based on the DC voltage and to output the driving voltage through a power line. The short detection unit may be configured to perform a short detection to detect whether the display panel is shorted based on a short detection reference that is adjusted according to an operation mode of the display panel.
