Abstract
A display device comprises a display panel that displays an image and has a data line and a sensing line, a data driver that drives the display panel, and a power supply part that delivers a driving reference voltage through a wiring line connected to the data driver. The data driver supplies a data signal to the data line, supplies the driving reference voltage through the sensing line, senses the sensing line based on an internally generated sensing reference voltage, and integrates a sensing result.
