Abstract

The invention discloses a grid driving circuit and a driving method thereof and a display device, and relates to the field of displaying. The grid driving circuit can reduce wiring space and realize frame narrowing of a panel and is particularly applicable to small-size panels. The grid driving circuit comprises a shifting register and a control unit, wherein the control unit is connected with an input end of the shifting register and used for converting first pulse signals output by the shifting register into multiple second pulse signals which are respectively used for driving a multiple grid lines.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate driving circuit, a driving method thereof, and a display device. Background technique [0002] The Gate Driver on Array (GOA) technology is a process technology that directly integrates gate driver ICs on the array substrate instead of an external driver chip. The application of this technology can not only reduce the production process, reduce product cost, improve integration, but also achieve a symmetrical and beautiful design on both sides of the panel, and also save the bonding (Bonding) area of ​​the gate circuit (Gate IC) and Fan-out (Fan-out) wiring space, so as to realize the design of narrow frame, improve production capacity and yield rate. [0003] Such as figure 1 As shown, the gate drive circuit using GOA technology includes a plurality of shift registers (SR1-SRn), ground voltage signal Vss supply lines, start pulse signal STV supply lines, first ...
