Abstract

The invention discloses a shifting register, a grid driving circuit, an array substrate and a display device. The shifting register comprises an input module and an output module and further comprises a grid signal generating module which is connected with the input module and the output module, wherein the input module comprises a first clock signal input end, a second clock signal input end, a third clock signal input end and a fourth clock signal input end, signals the same in phase and amplitude are input in the third clock signal input end and the second clock signal input end, and direct-current voltage signals are input in the fourth clock signal input end; the shifting register furthermore comprises a control module connected with the grid signal generating module, the control module comprises a seventh thin film transistor, a second capacitor and an eleventh thin film transistor, the third clock signal input end is connected with a grid of the seventh thin film transistor and a first end of the second capacitor, the fourth clock signal input end is connected with a source electrode of the eleventh thin film transistor, and the level of the point is a first level. Two sequence signals are added, in this way, discharging at the output ends is accelerated, and turn-off time of grid signals is shortened.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a shift register, a gate drive circuit, an array substrate and a display device. Background technique [0002] In recent years, with the vigorous development of semiconductor technology, portable electronic products and flat panel display products are also emerging. Thin Film Transistor (TFT) liquid crystal display has gradually become a standard output device for various data products due to its advantages of low operating voltage, no radiation scattering, light weight and small size. A TFT liquid crystal display is generally composed of a matrix of pixels arranged in both horizontal and vertical directions. When a TFT liquid crystal display is displayed, a gate input signal is generated through a shift register, and each row of pixels is scanned sequentially from the first row to the last row. When designing a TFT liquid crystal display, it is necessary to desig...
