Shifting register, grid-line driving circuit and display device

Abstract

The invention discloses a shifting register, a grid-line driving circuit and a display device. A first generation module generates a first clock signal under the control of four types of control signals; a pull-down driving circuit controls the potential of a second node under the control of a first clock signal end and a first node; a second generation module generates a second clock signal under the control of four types of control signals; an output module outputs the second clock signal by a signal output end; a pull-down module controls the potentials of the first node and the signal output end; and an input module and a resetting module control the potential of the first node. According to the shifting register, the grid-line driving circuit and the display device disclosed by the invention, by mutual matching of the five modules, when in normal display of a panel, different resolution ratios of a display screen can be switched at any time by generating different-frequency clock signals and switching different clock signals at any time, so that an intelligent display function is realized, random switching between high-definition display and a low-power-consumption mode of the panel is realized, the visual demand is met and the power consumption is effectively reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register, a gate line integrated drive circuit and a display device. Background technique [0002] In today's era of rapid technological development, liquid crystal displays have been widely used in electronic display products, such as televisions, computers, mobile phones and personal digital assistants. The liquid crystal display includes a data driver (Source Driver), a gate driver (Gate Driver), and a liquid crystal display panel. The liquid crystal display panel has a pixel array, and the gate driving device is used to sequentially turn on the corresponding pixel rows in the pixel array, so as to transmit the pixel data output by the data driver to the pixels, and then display the image to be displayed. [0003] At present, the gate driver is generally formed on the array substrate of the liquid crystal display through an array process, that is, the gate driver on ...
