Abstract

A drive circuit. A drive unit in the drive circuit comprises: a control unit (101) for controlling the output of a cascaded transmission signal; a cascaded transmission signal latching unit (102) for receiving the cascaded transmission signal, so as to generate a latching signal; first and second scanning signal generation units (103, 104); a first reversed phase output unit (105) for reversing the phase of a first scanning signal; and a second reversed phase output unit (106) for reversing the phase of a second scanning signal. Thus, a structure of a GOA circuit is simplified.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of driving, in particular to a driving circuit. [0003] 【Background technique】 [0004] The traditional GOA (Gate driver On Array) technical solution is generally to form the scanning drive circuit on the thin film transistor array substrate in the existing manufacturing process of the thin film transistor array substrate, so as to realize the pixel array on the thin film transistor array substrate. line-by-line scan. [0005] However, the structure of traditional GOA circuits is too complicated to meet the requirements of ultra-narrow bezels of display panels. [0006] Therefore, it is necessary to propose a new technical solution to solve the above technical problems. [0007] [Content of the invention] [0008] The purpose of the present invention is to provide a driving circuit, which can simplify the structure of the GOA circuit and meet the requirement of ultra-narrow frame of the display p...
