摘要： 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.

摘要： A display device may include a timing controller, a data driver and a plurality of pixels. The timing controller supplies a clock training pattern over a data/clock signal line in a first time period, and supplies pixel/control data over the data/clock signal line in a second time period. The data driver generates a clock signal, using the clock training pattern, in the first period, and generate a plurality of data voltages based on the plurality of pixel data, using the clock signal, in the second period. The plurality of pixels receive the plurality of data voltages and emit corresponding light. During the second period, the data driver outputs a feedback signal to the timing controller indicating that the locking of the clock signal has failed. The timing controller re-supplies the clock training pattern in response to the feedback signal.
