Abstract: A backlight unit includes a DC-DC converter that converts a first voltage to a second voltage in response to a driving pulse signal and a driving controller that outputs the driving pulse signal in response to an over-current control signal to control a reference voltage and a level of the second voltage. The driving controller controls the reference voltage in response to the over-current control signal such that the reference voltage increases prior to the second voltage by a predetermined time when the second voltage needs to be increased. In addition, the driving controller controls the reference voltage in response to the over-current control signal when the second voltage needs to be decreased such that the reference voltage decreases later than the second voltage by the predetermined time.

Abstract: A display device includes a display panel which includes a pixel including a driving transistor and a light-emitting element, and a sensing line connected to the pixel. A sensing driver senses a first sensing signal corresponding to mobility of the driving transistor through the sensing line, and processes the first sensing signal to output first sensing data. A driving controller receives the first sensing data from the sensing driver, generates mobility compensation data and kickback compensation data based on the first sensing data, and converts image data into compensation image data by the mobility compensation data and the kickback compensation data. A data driver converts the compensation image data into a data signal and provides the data signal to the pixel.
