Problems solved by technology

[0004] However, since each stage of the shift register in the existing GOA circuit can only be used to drive one gate line, the entire gate drive circuit occupies a large space, which is not conducive to the realization of narrow borders

Embodiment Construction

[0064] In order for those skilled in the art to better understand the technical solutions of the present invention, a gate driving unit, a driving method thereof, and a gate driving circuit provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0065] The transistors in the present invention can be thin film transistors or field effect transistors or other switching devices with the same characteristics. A transistor generally includes three poles: a gate, a source, and a drain. The source and drain in a transistor are symmetrical in structure, and the two can be interchanged as needed. In the present invention, the gate electrode refers to the gate of the transistor, one of the first electrode and the second electrode is the source, and the other is the drain.

[0066] In addition, according to the characteristics of transistors, transistors can be divided into N-type transistors and P-type transistors; when the tran...

Abstract

The invention discloses a gate drive unit, a drive method thereof and a gate drive circuit, comprising: a shift register and several output control modules, and each output control module is connected with a corresponding clock scanning signal line and a corresponding first The scanning signal output terminal; the output control module includes: the first output control submodule and the output reset submodule; the first output control submodule and the signal output terminal of the shift register, the corresponding clock scanning signal line, and the corresponding first scanning signal The output ends are all connected, and are used to send the clock scanning signal in the corresponding clock scanning signal line to the corresponding first scanning signal output end under the control of the signal output by the signal output end of the shift register for the first The scan signal output terminal outputs the first scan signal. The technical solution of the present invention can realize that one shift register can correspond to the driving of multiple gate lines, thereby effectively reducing the number of shift registers and being beneficial to narrow borders.

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, and a gate drive circuit. Background technique [0002] Most of the existing display devices adopt the design of gate drive integrated on the array substrate (Gate Drive On Array, referred to as GOA). Compared with the existing chip on film (Chip On Film, referred to as COF) technology or chips directly fixed Chip On Glass (COG for short) process, which not only saves costs, but also achieves a symmetrical and beautiful design on both sides of the panel, and can also save the bonding area of ​​the gate drive circuit and the peripheral wiring space. [0003] A GOA circuit generally includes several cascaded gate drive units, and the existing gate drive unit is specifically a shift register. The signal output terminals of each shift register in the GOA circuit are separately connected to a corresponding gate line, and the shift r...
