Abstract

Embodiments of the present invention provide a shift register and its driving method, gate driving circuit, and display device, which relate to the field of display technology and can solve the problem of unstable output caused by insufficient pull-down node potential in the shift register; the shift register The bit register includes a pull-up node, a pull-down node, and a pull-down coupling subcircuit; the pull-down coupling subcircuit is connected to the pull-down node, the first scanning end, and the second scanning end; the pull-down coupling subcircuit is configured to: at the first scanning end and the second scanning end Under the control of the signal at the terminal, the voltage of the pull-down node is coupled and raised.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a shift register and a driving method thereof, a gate driving circuit and a display device. Background technique [0002] GOA (Gate Driver on Array, array substrate row drive) is a technology that integrates a gate driver circuit on an array substrate, wherein the GOA circuit includes a multi-stage cascaded shift register, and each stage of the shift register is connected to the array substrate. A row of gate lines is connected, and is used for outputting gate scanning signals to the gate lines, so as to realize line-by-line scanning (driving) of a plurality of gate lines in the display panel. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide a shift register and a driving method thereof, a gate driving circuit, and a display device, which can solve the problem of unstable output caused by insufficient potential of a pull-down node in ...
