Abstract: A display device includes a display panel, controller configured to generate a second data enable signal and second image data based on a first data enable signal and first image data, and generate an output data enable signal and output image data by performing a black data insertion operation, and data driver configured to provide data signals based on the output data enable signal and the output image data, where the controller obtains a delay time between the first data enable signal and the second data enable signal or the first image data and the second image data, determines a number of subsequent pulses of the output data enable signal during a period from one time point within a frame period to an end time point of the frame period, and adjusts a cycle of the subsequent pulses based on the delay time and the number of the subsequent pulses.

Abstract: Provided is a backlight unit. According to an exemplary embodiment, the backlight unit includes a plurality of light emitting strings, each of which includes at least one light emitting diode and one light transistor that is electrically connected to the light emitting diode, and a driving controller configured to detect source voltages of a plurality of light transistors provided in the light emitting strings. The driving controller is further configured to compare a source voltage of each of the light transistors with an overcurrent protection voltage and to turn off an operation of a corresponding light transistor having a source voltage level higher than the overcurrent protection voltage.
