Abstract: A display device includes a voltage supply unit to output a first voltage, a switch unit to selectively output the first voltage or a second voltage, a coupling member to transfer a third voltage to a display panel, and a feedback unit to selectively feed back the first voltage or the third voltage. The voltage supply unit receives a voltage based on the first voltage or the third voltage selected by the feedback unit, and the third voltage is based on the first voltage output from the switch unit. The voltage supply unit may compensate for drops in a control voltage of the display panel based on the fed back voltage.
