Abstract

The invention discloses a shift register, a gate line integrated driving circuit and a display device. A first generating module generates a first clock signal under the control of four control signal terminals; a pull-down driving module is connected to the first clock signal terminal and the first clock signal terminal. Under the control of the node, the potential of the second node is controlled; the second generation module generates a second clock signal under the control of four control signal terminals; the output module outputs the second clock signal through the signal output terminal; the pull-down module controls the first node and the potential of the signal output terminal; the input module and the reset module control the potential of the first node. Due to the cooperation of the above five modules, when the panel is displayed normally, by generating clock signals of different frequencies and switching different clock signals at any time, the display screen can switch between different resolutions at any time, thereby realizing intelligent display. It can realize the random switching of panel high-definition display and low-power mode to meet visual needs and effectively reduce power consumption.

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 ...
