1. A display device comprising:
a pixel including a first transistor having a drain electrode that is connected to a first power voltage node and a source electrode that is connected to a second power voltage node, a second transistor connected between a data line and a gate electrode of the first transistor, and a third transistor connected between a sensing line and the source electrode of the first transistor;
a data driver connected to the pixel through the data line, the data driver applying a bias voltage to the data line during a sensing period of a frame period, wherein the frame period includes the sensing period and a display period;
a sensing driver connected to the pixel through the sensing line, the sensing driver sensing an electrical characteristic of the pixel through the sensing line during the sensing period; and
a controller configured to control a first power voltage for the frame period according to input image data, and adjust the bias voltage according to the first power voltage and the electrical characteristic of the pixel.
