Abstract

The invention brings forward a grid electrode drive circuit comprising multiple stages of grid electrode driving units. Each stage of grid electrode driving unit comprises a first switch element to a tenth switch element and a first capacitor; And the grid electrode driving unit receives a first clock signal to a fifth clock signal, a first pulse signal, a second pulse signal and a reference low voltage. The invention also provides a display apparatus. According to the grid electrode drive circuit and the display apparatus of the present invention, grid electrode driving signals are stabilized through utilization of the ninth switch element and the tenth switch element, thereby guaranteeing driving capability of the circuit and facilitating the design of a narrow frame of the circuit.

Description

technical field [0001] The invention relates to a driving circuit, in particular to a gate driving circuit and a 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 data lines, and each pi...
