Abstract
A gate driver circuit, a display panel, and a display device. A number of emission start signals, with at least one a delay time, a pulse width, or a combination thereof, are supplied in a frame period in which display driving is performed at a low driving frequency. This decreases a degree by which luminance appearing in the frame period is reduced, or changes characteristics of frequency components of luminance, thereby preventing flicker from being observed. The display driving is performed at the low driving frequency reduces power consumption, and is performed at a lower driving frequency to improve the efficiency of the display device.
