Grid driving circuit and display device using same

Abstract

The invention provides a grid driving circuit. The grid driving circuit comprises multiple levels of grid driving units, and each level of grid driving unit comprises a first switching element, a second switching element...a ninth switching element. All the levels of grid driving units receive external signals including a first clock signal, a second clock signal, a first steady signal, a second steady signal, first grid driving signals output by the grid driving units higher than the grid driving units for receiving the external signals by two levels and second grid driving signals output by the grid driving units lower than the grid driving units for receiving the external signals by two levels. According to the grid driving circuit, the sixth switching elements and the ninth switching elements are controlled by the first steady signal and the second steady signal to work intermittently, noise, generated by clock hopping, of an output level is reduced, meanwhile, influences on the stability of the grid driving signals from the sixth switching elements and the ninth switching elements are reduced, therefore, the stable grid driving signals can be output, the reliability is high and design is simple.

Description

technical field [0001] The invention relates to a driving circuit, in particular to a gate driving circuit and a display device using the same. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as lightness, lightness, energy saving, and no radiation, 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 (Thin Film Transistor, 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 The polar line intersects two adjacent data lines to form a pixel unit, and each pix...
