Abstract

The invention discloses a shift register, a grid driving circuit and a display panel. The shift register comprises a control module and an output module, wherein the control module is used for changing potential of a first node and a second node through signals of a first clock signal end, signals of a reference signal end and signals of a signal input end under the control of the first clock signal end and the signal input end; and the output module is used for outputting the signals of the reference signal end through a scanning signal output end under the control of the first node and outputting signals of a second clock signal end through the scanning signal output end under the control of the second node. In such a way, the shift register provided by the embodiment of the invention realize normal output of scanning signals through the control module and the output module, at the same time, the shift register only comprises the control module and the output module, the structure is simple, the power consumption is low, and realization of narrow-frame design of the display panel is facilitated.

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, with the development of display technology, the competition in the display panel industry is becoming more and more fierce. Reducing the production cost of display panels has become the first choice for panel manufacturers to improve their competitiveness. In order to reduce the production cost of display panels, generally, Technicians use the edge of the display panel to build a gate drive circuit. The gate drive circuit includes multiple shift registers, each of which corresponds to a gate line. Multiple shift registers are cascaded, and two adjacent shift registers There are trigger signals transmitted step by step between the bit registers. After each shift register receives the trigger signal, it outputs the gate line scanning signal to the corresponding gate line, and send...
