Abstract: A pixel driver includes a plurality of stages, with each stage including a pixel driving signal generator, a shift register, and a selection circuit. The pixel driving signal generator generates a pixel driving signal. The shift register receives image data and the pixel driving signal and generates an output control signal for determining whether to output the pixel driving signal based on the image data and the pixel driving signal. The selection circuit selectively outputs the pixel driving signal in response to the output control signal.

Abstract: A display device which includes a display panel that includes a first display area and a second display area, and a driving controller. During a multi-frequency mode, the driving controller drives the first display area by using a first driving frequency and drives the second display area by using a second driving frequency. During the multi-frequency mode, when the second driving frequency changes from a first frequency to a second frequency, the driving controller drives the first display area and the second display area during at least one frame by using a base frequency, drives the first display area and the second display area during at least one second frame by using an intermediate frequency between the base frequency and the second frequency, and then drives the first display area by using the first driving frequency and drives the second display area by using the second frequency.
