Abstract

A display device includes a display panel including a pixel including a light emitting element emitting light and electrically connected to a data line and a sensing line, a timing controller varying a driving frequency of the display panel based on an input frequency of digital video data, and a data driver supplying a data voltage to the data line based on the digital video data during a data addressing period of a frame period and receiving a sensing signal from the sensing line during a sensing period. The data driver electrically connects the sensing line to an initialization voltage line during the data addressing period in case that the digital video data is changed, and electrically connects the sensing line to a high impedance during the data addressing period in case that the digital video data is not changed.
