Abstract

The invention discloses a shift register electrode, a grid electrode driver, an array substrate and a display device, relating to the technical field of liquid crystal display. The electrode comprises a pull-up module, a first pull-down module, a second pull-down module, a pull-up drive module, a pull-down drive module and a reset module, wherein the first pull-down module is used for outputting shut-off signals to an output terminal according to signals input from a clock block signal input terminal and signals input from a reset signal input terminal; the second pull-down module is used for outputting shut-off signals to the output terminal according to signals input from a clock signal input terminal; and the phases of signals input from a signal input terminal are the same with those of the signals input from the clock signal input terminal, and the phases of the signals input from the clock signal input terminal are the same with those of the signals input from the clock block signal input terminal. The shift register electrode can be used for effectively avoiding the defect of threshold voltage drift caused by bias stress on a grid electrode, and can reduce noises generated during outputting voltages.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a stage of a shift register, a gate driver, an array substrate, and a display device. Background technique [0002] A Liquid Crystal Display (LCD) has the advantages of light weight, thin thickness, and low power consumption, and is widely used in electronic products such as televisions, mobile phones, and monitors. [0003] The LCD is composed of a matrix of pixels in both horizontal and vertical directions. When displaying, the gate input signal is output through the gate drive circuit, and each pixel is scanned row by row. The driving of the LCD mainly includes a gate driver and a data driver. The data driver latches the input display data and the clock signal in a timing sequence, converts it into an analog signal and then inputs it to the data line of the LCD panel, and the gate driver shifts the input clock signal Register conversion, switching to on...

Problems solved by technology

The advantage of this design is that there is no need to change the current shift register circuit diagram, but the disadvantage is that if this scheme is adopted, the node PD is designed to be high potential and half high potential, which will make TFT M10 and TFM11 in a long-term on state

The threshold voltage of TFT has a great relationship with the voltage applied to its gate and the time when the gate voltage is applied. Under long-term gate voltage, the threshold voltage of TFT will drift greatly, so that The life of the shift register of the driver is greatly reduced, which affects the normal operation of the entire gate driver
