Shift register unit, gate drive circuit and display panel

Abstract

The invention provides a shift register unit, a gate drive circuit and a display panel. The shift register unit comprises a pull-up control module connected with an (n-1) th-stage scanning signal output end, a first node and a third node; a pull-up module connected with a first clock signal, wherein the first node is connected to the scanning signal output end of the current stage; an anti-creeping module connected with the first clock signal and the third node; a pull-down control module connected with a (n + 2) th-stage scanning signal output end and a second node; and a first pull-down module connected with a (n + 2) th-stage scanning signal output end, the first node, the second node and the third node. According to the shift register unit, the gate drive circuit and the display panel,electric leakage of a Q point can be avoided, and the stability of the shift register unit is improved.

Description

【Technical field】

[0001] The present invention relates to the field of display technology, in particular to a shift register unit, a gate drive circuit and a display panel. 【Background technique】

[0002] Usually, a gate drive circuit is provided on the edge of the display panel, and the gate drive circuit includes a plurality of cascaded shift register units. level in order to enable the pixel to be displayed. When the upper-stage shift register unit receives the signal and completes the shift, the output signal will be transmitted to the next-stage shift register unit cascaded with it, thereby realizing the function of progressive scanning.

[0003] However, during the shifting process of the current shift register unit, the transistors in the pull-up module and the pull-down module will have a serious leakage problem at the Q point due to the excessive voltage difference between the source and the drain, which reduces the shift. The stability of the storage unit. [00...
