Abstract

The invention provides a shift registration unit comprising an input module, a driving module, a pull-down module, a pull-down control module, a high level input end, a low level input end, a first clock signal end, a second clock signal end, a signal input end, and a signal output end. The control end of the pull-down control module is connected with the signal input end, and the first input end of the pull-down control module is connected with the high level signal input end. The second input end of the pull-down control module is connected with the first clock signal end, and the third input end of the pull-down control module is connected with the low level signal input end. The output end of the pull-down control module is connected with the control end of the pull-down module, and the pull-down control module is used for exclusive or operation of an input signal input by the signal input end and a first clock signal input by the first clock signal end. The invention also provides a shift register, a grid driving circuit, and a display device. The shift registration unit provided by the invention is used to guarantee output of high level signals in an output phase.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a shift register unit, a shift register including the shift register unit, a gate drive circuit including the shift register, and a gate driver circuit including the gate drive circuit. The display device of the driving circuit. Background technique [0002] In a display device, a gate driving circuit is used to provide a scan signal that scans the gate lines of the display panel to be turned on row by row. The gate drive circuit includes cascaded multi-stage shift register units, and each stage of shift register units corresponds to a row of gate lines. [0003] However, in the prior art, there is a phenomenon that the shift register unit cannot be turned off well, resulting in false turn-on of the gate line. Contents of the invention [0004] The object of the present invention is to provide a shift register unit, a shift register including the shift register unit...
