Display device and method of driving the same

Abstract

A display device includes a display panel which displays an image, a data driver which supplies a plurality of data signals to the display panel, a first power supply which supplies a data driving voltage to the data driver through a first power supply line, and a second power supply which supplies a first driving voltage to the display panel through a second power supply line. The first power supply senses a voltage of the second power supply line and controls the supply of the data driving voltage based on a sensed voltage during an initial driving period, in which the first power supply generates the data driving voltage and the second power supply does not generate the first driving voltage.
