Abstract
A gate driving circuit is disclosed which includes n stages that are sequentially arranged, n being an integer larger than or equal to 4. The n stages are divided into a first, second, third and fourth sets of stages that are configured to receive respective different combinations of a first clock signal, a second clock signal, a third clock signal and a fourth clock signal. The stages in the first set of stages and the stages in the third set of stages are cascaded with each other, and the stages in the second set of stages and the stages in the fourth set of stages are cascaded with each other. Also disclosed are an array substrate including the gate driving circuit, a display panel including the array substrate, and a driving method of the display panel.
