Abstract

The invention discloses a shifting register, a gate drive circuit and a display panel. The shifting register can output normal scanning signals to a gate line through an input module, a first control module, a second control module and an output module; compared with the shifting register in the prior art, the structure of an inverter is omitted for a circuit structure of the shifting register; and the circuit structure is simple and conducive to improvement of signal distortion. In addition, the output module in the shifting register outputs a first power signal and a second power signal at different time periods separately under the control of a second node and a third node, so that the phenomenon of competition caused by short-circuit current between the first power signal and the second power signal can be prevented.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register, a gate drive circuit and a display panel. Background technique [0002] At present, display technology is widely used in the display of TV, mobile phone and public information. Flat-panel displays used for displaying images are being vigorously promoted because of their ultra-thin and energy-saving advantages. Most flat-panel displays require gate integrated drivers. The circuit is used to output gate scanning signals to control the display panel to realize the function of progressive scanning, so that the image data input to the display panel can be refreshed in real time, thereby realizing dynamic display. The gate integrated drive circuit includes a plurality of shift register units cascaded and corresponding to the gate lines one by one, and the scan signal is input to the corresponding gate line through the shift register unit, so as to realize the functio...
