Gate driving unit, driving method thereof, gate driving circuit and display device

Abstract

The invention discloses a gate driving unit and a driving method thereof, a gate driving circuit and a display device, comprising: a shift register and a plurality of driving signal output modules, the driving signal output modules are in one-to-one correspondence with gate lines on an array substrate , each driving signal output module is connected with the first power supply terminal and the signal output terminal of the shift register, each driving signal output module is also connected with the corresponding driving scanning signal line, and the driving signal output module is used for the signal in the shift register. Under the control of the signal output from the output end, the drive scan signal in the corresponding drive scan signal line or the off voltage provided by the first power supply end is output to the corresponding gate line. The technical scheme of the present invention can realize the use of one shift register to control the driving of multiple gate lines, thus greatly reducing the number of shift registers in the gate driving circuit, thereby effectively reducing the occupied space of the gate driving circuit.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate drive unit, a drive method thereof, a gate drive circuit and a display device. Background technique [0002] Each stage of the shift register in the existing gate drive circuit can only be used to drive one row of gate lines, so the number of shift registers that need to be set in the entire gate drive circuit is large, resulting in a large number of shift registers in the entire gate drive circuit. It takes up a lot of space, which is not conducive to the realization of narrow borders. [0003] It can be seen that how to effectively reduce the occupied space of the gate driving circuit is a technical problem urgently needed to be solved by those skilled in the art. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art, and proposes a gate drive unit, a drive method thereof, a gat...
