A display device comprises a timing control circuit, a driving circuit, a display panel, and a DC voltage conversion circuit. The timing control circuit generates a data signal based on an input image signal. The driving circuit is driven by a first DC voltage; generates a first conversion control signal and a second conversion control signal indicating the state of the first conversion control signal; and generates a driving signal based on the data signal. The display panel is driven by a second DC voltage; and includes a plurality of pixels based on the driving signal. The DC voltage conversion circuit includes a first DC voltage current unit and a second DC voltage current unit, wherein the first DC voltage conversion unit generates a first DC voltage based on an external voltage, and the second DC voltage conversion unit generates a second DC voltage based on an external voltage. The DC voltage conversion circuit time-divides the first and second voltage conversion units in response to the first and second conversion control signals, and controls the same. |
