Abstract
A display device includes a display panel includes a plurality of pixels driven by a first power voltage and a second power voltage. A display panel driving circuit is configured to receive image data from an external device, output a first voltage control signal for generating an analog supply voltage based on an on-pixel ratio (OPR) of the image data, and output a second voltage control signal for generating the first power voltage and the second power voltage. A DC-DC conversion circuit is configured to generate the analog supply voltage based on the first voltage control signal and generate the first power voltage and the second power voltage based on the second voltage control signal.
