Claim:
1. A display device, comprising: a display panel including a plurality of pixels, the pixels being configured to operate in response to a first driving voltage, a second driving voltage, and a data signal; a voltage converter that provides the first driving voltage and the second driving voltage to the display panel, the voltage converter including a first output, which outputs the first driving voltage to first wiring of the display panel, and a second output, which outputs the second driving voltage to second wiring of the display panel, the voltage converter selectively starting an output of the second driving voltage after a detection period, the detection period being after the output of the first driving voltage; and a comparator configured to control the output of the first and second driving voltages of the voltage converter based on a magnitude of a wiring voltage corresponding to voltage on the second wiring.
