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.

Abstract: A display device includes a data line, a pixel electrically connected to the data line, a data driver for outputting a data voltage, and a transmitter electrically connected between an output terminal of the data driver and the data line. The transmitter may transmit an instance of the data voltage to the data line in a first period. The transmitter may amplify a second instance of the data voltage to generate a reference voltage and then transmit the reference voltage to the data line in a second period different from the first period. The pixel includes a light emitting element for emitting light in response to the first instance of the data voltage. A voltage level of the reference voltage may be higher than a voltage level of the data voltage.
