The noise of the output end can be effectively reduced.

Description

technical field [0001] The present disclosure relates to a shift register and an operation method thereof, a gate driving circuit and a display device. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) is widely used in various fields of production and life, and it adopts a progressive scan matrix display with M*N dot arrangement. When displaying, the TFT-LCD drives each pixel in the display panel to display through a driving circuit. The driving circuit of TFT-LCD mainly includes gate driving circuit and data driving circuit. Wherein, the data driving circuit is used for sequentially latching the input data according to the timing of the clock signal and converting the latched data into analog signals to be input to the data lines of the display panel. The gate driving circuit is usually realized by a shift register, and the shift register converts the clock signal into an on / off voltage, which is respectively output to each gate line of ...
