Abstract

The invention discloses a shift register and a display panel. The shift register comprises an output adjusting module which is used for adjusting an output signal of the shift register according to signals on a first node and a second node, a trigger write-in module which is used for writing a trigger signal into the second node according to a set clock signal, and a node adjusting module which isused for adjusting a signal on the first node and comprises a power supply leading-in sub-module, a first adjusting sub-module and a coupling sub-module, wherein the power supply leading-in sub-module is used for leading a first power supply signal into the control end of the first adjusting sub-module according to an input signal of the control end of the power supply leading-in sub-module so asto turn off the first adjusting sub-module; the coupling sub-module is used for coupling the first clock signal to the control end of the first adjusting sub-module; and the first adjusting sub-module is used for adjusting a signal on the first node according to an input signal of the control end of the first adjusting sub-module. The shift register can improve the working stability of the shiftregister.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of shift registers, in particular to a shift register and a display panel. Background technique [0002] A shift register is a device that shifts an output signal relative to an input signal, and has important applications in modern electronic circuits, such as display panels. [0003] However, the stability of the shift register in the existing display panel is poor, and it is easy to cause phenomena such as flickering, which seriously affects the display effect. Contents of the invention [0004] The invention provides a shift register and a display panel to improve the working stability of the shift register. [0005] In a first aspect, an embodiment of the present invention provides a shift register, including: an output adjustment module, configured to adjust an output signal of the shift register according to signals on a first node and a second node; a trigger writing mod...
