Problems solved by technology

Since the feedback structure of the traditional GOA circuit only designs gate pulse feedback points on the last two levels of horizontal scanning lines, it will not be possible to confirm which level of the gate pulse signal in the entire GOA circuit is the worst signal position

Abstract

The invention provides an array substrate line drive circuit which comprises a first feedback routing, a second feedback routing, a third virtual feeder line and a fourth virtual feeder line, wherein the first feedback routing is used for measuring grid pulse signals of a first-level horizontal scanning line; the second feedback routing is used for measuring grid pulse signals of a second-level horizontal scanning line; the third virtual feeder line is used for measuring grid pulse signals of a (N-1)-level horizontal scanning line; the fourth virtual feeder line is used for measuring grid pulse signals of an N-level horizontal scanning line.Compared with the prior art, feedback nodes targeted to the first two levels of horizontal scanning lines are additionally added, and the grid pulse signals at the head end and the tail end can be directly measured from a printing circuit board at the same time so as to determine the poorest pulse position.

Description

technical field [0001] The present invention relates to a liquid crystal display, in particular to an array substrate row driving (GateDriveronArray, GOA) circuit for a liquid crystal display. Background technique [0002] Liquid Crystal Displays (Liquid Crystal Displays, LCDs) have many advantages such as thin bodies, power saving, and no radiation, and thus have been widely used, and gradually occupy a dominant position in the field of flat panel displays. For example, liquid crystal displays have been used in various occasions such as liquid crystal televisions, mobile phones, personal digital assistants (Personal Digital Assistance, PDA), digital cameras, desktop computer screens or notebook computer screens. [0003] Most of the liquid crystal displays in the prior art are backlight liquid crystal displays, which include a liquid crystal panel and a backlight module. The working principle of the liquid crystal panel is to pour liquid crystal molecules between the thin ...
