Embodiment Construction

[0034] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] Although the present invention uses the terms first, second, third, etc. to describe various elements, signals, ports, components or sections, these elements, signals, ports, components or sections are not limited by these terms. These terms are only used to distinguish one element, signal, port, component or section from another element, signal, port, component or section. In the present invention, an element, port, component or part is "connected" or "connected" to another element, port, component or part, which can be understood as a direct electrical connection, or can also be understood as an indirect electrical connection with an intermediate element. sexual connection. Unless otherwise defined, all terms (including techn...

Abstract

The invention provides a gate drive circuit, which at least comprises at least one group of gate drive units, wherein each group of gate drive unit comprises a primary gate drive unit and at least one combined gate driving unit and at least comprises first to thirteenth switch elements; the first to ninth switch elements form the primary gate drive unit for outputting a primary gate drive signal; the tenth to thirteenth switch elements form a first combined gate drive unit which is used for outputting a next gate drive signal. Each group of gate drive unit of the gate drive circuit shares the multiple switch units, so the number of the switch elements is reduced, the power consumption is low and the design of a narrow frame is facilitated.

Description

technical field [0001] The invention relates to a driving circuit, in particular to a grid driving circuit suitable for a liquid crystal display device. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as light and thin, energy-saving, non-radiation, etc., so it has gradually replaced the traditional cathode ray tube (CRT) display. Currently, liquid crystal displays are widely used in high-definition digital televisions, desktop computers, personal digital assistants (PDAs), notebook computers, mobile phones, digital cameras and other electronic devices. [0003] Taking a thin film transistor (ThinFilmTransistor, TFT) liquid crystal display device as an example, it includes: a liquid crystal display panel and a driving circuit, wherein the liquid crystal display panel includes a plurality of gate lines and a plurality of data lines, and two adjacent gate lines A pixel unit is formed by intersecting with two adjacent...
