Abstract: A display device includes: pixels connected to corresponding scan lines, control lines, data lines, and sensing lines, a scan driver which supplies a scan signal to the scan lines, and supplies a control signal to the corresponding control lines, a data driver which supplies one of an image data signal and a sensing data signal to the corresponding data lines, and a sensing driver which senses characteristics of driving transistors of different pixels of the pixels in a previous sensing period and a current sensing period, and determines a final sensing value of a target pixel of the pixels in the current sensing period, based on a difference between a previous sensing value of the target pixel, which is determined based on the sensing in the previous sensing period, and a preliminary sensing value of the target pixel, which is calculated based on the sensing in the current sensing period.

Abstract: A display device includes a pixel component including first pixels which emits light having a first color, and second pixels which emits light having a second color different from the first color, a sensing component which extracts, during a sensing period, first sensing data from the first pixels, and second sensing data from the second pixels, and a temperature determiner which senses a temperature of the pixel component using the first sensing data and the second sensing data. The temperature determiner senses, when the first sensing data is supplied to the temperature determiner, the temperature of the pixel component at least one time.
