Abstract

The invention discloses a shifting register, a driving method for a display panel and a related device. An output control unit, a second pull-up unit, a second pull-down unit and a selection control signal end are additionally arranged in the shifting register and used for selecting whether the driving output end outputs a scanning signal or not, and then the scanning signal can be selectively output to part of grid lines in a grid driving circuit. Further, the grid driving circuit is adopted in the display panel, a switch device between a third node connected with two shifting registers and a fourth node connected with the two shifting register and a mode switching circuit are additionally arranged. In this way, the mode switching circuit makes the display panel display information at different resolution ratios according to different mode control signals, power consumption of the display panel can be reduced selectively, and the stand-by time is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register, a driving method of a display panel and related devices. 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 assistant devices. 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 drive...
