Abstract: Provided is a display device that includes, for example, a display panel, a driver, a power supply unit, and a timing controller. The power supply unit may supply a voltage to the driver. The power supply unit may perform a compensation operation to vary an output voltage output from the power supply unit itself to correspond to a variation of a load before the load varies.

Abstract: The present disclosure provides a gate clock generator including a counter, a buffer control signal generator, and an output unit. The counter receives control data having rising timing information and falling timing information and a main clock. The counter generates a first output when a value is obtained by counting the main clock from a preset reference time point reaches rising data. The counter further generates a second output when a value is obtained by counting the main clock from the reference time point reaches falling data. The buffer control signal generator generates a first buffer control signal of a gate ON voltage from a timing of the first output to a timing of the second output. The output unit outputs a gate ON voltage of a gate clock during an output period of the gate ON voltage of the first buffer control signal.
