Claim:
1. A display device, comprising: a display panel including a plurality of pixels to be driven based on a first power voltage and a second power voltage; a display panel driver to divide one frame into a first pulse period, a second pulse period, and a third pulse period, and to output a control signal to generate an analog supply voltage, the first power voltage, and the second power voltage, the display panel driver to be driven based on the analog supply voltage; and a DC-DC converter electrically coupled to the display panel driver, the DC-DC converter to receive the control signal from the display panel driver through a single wire, wherein the DC-DC converter includes: an analog supply voltage generator to generate the analog supply voltage during the first pulse period, a first power voltage generator to generate the first power voltage during the second pulse period, and a second power voltage generator to generate the second power voltage during the third pulse period.
