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.

Abstract: A display device includes: a display panel including a plurality of pixels; a source driver for outputting a target initialization voltage in an analog format to the pixels through sensing lines; and a timing controller for providing the source driver with a data control signal including packet information associated with the target initialization voltage. The packet information is in a digital format. The source driver includes a digital-analog converter which generates the target initialization voltage in the analog format, based on the packet information.

Abstract: A display device includes: a timing controller which receives image data including high logics and low logics from the outside; a data driver which generates a data signal, based on the image data; and pixels which emit light with a luminance corresponding to the data signal, where the data driver determines an error of the image data, based on a checksum included in the image data.
