Abstract
A light emitting display device includes a display panel, a power supply configured to supply a first potential voltage and a second potential voltage to the display panel, and a switch circuit unit configured to sense the first potential voltage applied to the display panel and to feedback the first potential voltage to the power supply, wherein the power supply compensates for the first potential voltage based on the first potential voltage fed back from the switch circuit unit and to output the compensated first potential voltage.
