[0039] The stages of the shift register, the gate driver, the array substrate, and the display device proposed by the present invention are described in detail below with reference to the drawings and embodiments.
[0040] The core idea of the present invention is: by adding a pull-down module, on the basis of the original shift register stage, when the clock input signal CLK arrives, the coupling voltage of the pull-up node PU (that is, the noise of the pull-up node PU) is performed Discharge to reduce the noise, and at the same time discharge the output terminal, thereby reducing the output signal noise and increasing the stage stability of the shift register; at the same time, by adding the pull-down module, the TFT of the original pull-down module is reduced State time, reduce the application time of the gate bias stress, thereby prolonging the working life of the original TFT, thereby extending the life of the shift register stage, the entire shift register, the gate driver...
