Abstract

The invention discloses a shift register, a gate drive circuit and a drive method thereof. The shift register comprises a display pre-charging reset sub-circuit, a sensing pre-charging reset sub-circuit, a pull-down control sub-circuit, an output sub-circuit, a sensing cascade sub-circuit and a black insertion cascade sub-circuit, wherein the black insertion cascade sub-circuit is used for providing a signal of a second signal input end for the sensing cascade node under the control of a second random signal end. By arranging the black insertion cascade sub-circuit, black insertion can be performed on the other part of the screen of the display panel in the display gap of the part of the screen of the display panel, so that the time required for writing black data is shortened, and the high refresh rate of the display panel is ensured while the moving image response time of the display panel is prolonged.

Description

technical field [0001] The embodiments of the present application relate to but are not limited to the field of display technology, and in particular, relate to a shift register, a gate driving circuit and a driving method thereof. Background technique [0002] With the continuous development of science and technology, various display devices emerge in an endless stream, bringing great convenience to people's production and life. [0003] During the display process of a display panel, especially an Organic Light Emitting Diode (OLED) display panel (Organic Light Emitting Diode, OLED), an image smear phenomenon will occur when a dynamic picture is switched, that is, when the display panel switches from one frame to another frame, the user You will feel the image smear (also called dynamic image smear) of the previous frame, which will affect the display effect. Contents of the invention [0004] Embodiments of the present application provide a shift register, a gate drivin...
