Shifting register unit, driving method thereof, grid driving circuit and display device

Abstract

The embodiment of the invention provides a shifting register unit and a driving method thereof, a gate driving circuit and a display device, relates to the technical field of display, and aims to reduce the GOA size and facilitate a display panel to realize a narrow frame. The shifting register unit is characterized in that a first output sub-circuit transmits a clock signal of a clock signal endto a signal output end under the control of a pull-up node; the first second output sub-circuit in the N second output sub-circuits transmits the signal of the signal output end to the first output end under the control of the first signal end; the ith second output sub-circuit in the N second output sub-circuits is controlled by the ith signal end; wherein N is a positive integer larger than or equal to 2, i is larger than or equal to 2 and smaller than or equal to N, and i is a positive integer.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a shift register unit, a driving method thereof, a gate driving circuit, and a display device. Background technique [0002] GOA (Gate Driver on Array, integrated gate drive circuit) technology can integrate the gate drive circuit on the array substrate of the display panel, replacing the drive chip made of external silicon chips, and can save Gate IC (Gate Integrated Circuit, gate Driver integrated circuit) part and fan-out (Fan-out) wiring space to simplify the structure of display products. [0003] The current GOA design is that each gate line corresponds to a GOA unit, and the structure of the GOA unit, for example, includes 11 thin film transistors (Thin Film Transistor, referred to as TFT) and 1 storage capacitor (Capacitance, referred to as C), when it is applied In large-size or vehicle-mounted display products, for the sake of reliability, the number of TFTs i...

[0003] The current GOA design is that each gate line corresponds to a GOA unit, and the structure of the GOA unit, for example, includes 11 thin film transistors (Thin Film Transistor, referred to as TFT) and 1 storage capacitor (Capacitance, referred to as C), when it is applied In large-size or vehicle-mounted display products, due to reliability considerations, the number of TFTs in each GOA unit is relatively large, which increases the size of the GOA, resulting in wider borders of the display panel
