Classification: CPC G  H | IPC G  H

Claim 0:
1. A display device, comprising:
a display panel comprising a plurality of pixels, the plurality of pixels being configured to operate in response to a first driving voltage, a second driving voltage, and a data signal corresponding to image data;
a display panel driver configured to drive the display panel, the display panel driver comprising a gate driver to provide a gate signal to the display panel, a data driver to provide the data signal to the display panel, and a timing controller to receive the image data, a vertical synchronization signal, a horizontal synchronization signal, and a data enable signal from an external graphic controller to control the gate driver and the data driver; and
a power converter configured to provide the first driving voltage at a first output electrode of the power converter and the second driving voltage at a second output electrode of the power converter at a time interval of a short detection period,
wherein the power converter is to compare a magnitude of a reference voltage with a magnitude of a voltage of the second output electrode during the short detection period to shut down when the magnitude of the voltage of the second output electrode is equal to or larger than the magnitude of the reference voltage during the short detection period.
