Abstract
A display device includes a display panel including a plurality of pixels connected to data lines and sensing lines, a data driver including a plurality of buffer amplifiers which supplies a first sensing voltage to the data lines during a first sensing period and a sensor which receives a first sensing signal from the pixels through the sensing lines during the first sensing period, and a global amplifier which supplies a second sensing voltage to the data lines during a second sensing period different from the first sensing period. The sensor receives a second sensing signal corresponding to the second sensing voltage from the pixels through the sensing lines during the second sensing period, and generates compensation data based on a difference value between the first sensing signal and the second sensing signal.
