Abstract

The invention provides a unit circuit of a shifting register. The unit circuit comprises an input end, an output end, a grid drive end, a first node, a second node, a first signal end, a second signal end, a control signal end, an output control module, a selective control module, an inverse-phase control module, an input control module and a grid drive module. According to the unit circuit of the shifting register, the input control module responds to an initial signal input from the input end, and then controls the work state of the output control module, so as to control the output voltage of the output end, the output control module responds to a first clock signal and a second clock signal, and outputs a scanning signal through the output end, then the selective control module responds to the first clock signal or the second clock signal, so as to provide a control signal to the output end, thus the multiplex control is realized, and the circuit has the advantage of long service life.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a shift register unit circuit, a shift register and a liquid crystal display thereof. Background technique [0002] With the rapid development of science and technology, liquid crystal displays have been widely used in electronic display products, such as TVs, notebook computers, tablet computers, smart phones, etc. The liquid crystal display includes a data driver, a shift register and a liquid crystal display panel, wherein the liquid crystal display panel has a pixel array, and the shift register is used to sequentially turn on corresponding pixel columns in the pixel array, so as to scan the pixel data output by the data driver to The pixel row, and then display the image corresponding to the pixel data. [0003] Nowadays, manufacturers mostly use shift registers to form scan drivers that can sequentially turn on the corresponding pixel columns in the pixel array...
