Problems solved by technology

[0004] The traditional panel refresh rate is 60Hz, which means that the screen is refreshed 60 times per second, and each refresh is to charge and discharge each display pixel in the display area; but if it is a static picture, it will still be refreshed continuously. Will cause a lot of unnecessary power loss

Abstract

The invention discloses a display panel. The display panel comprises a substrate, a data driving circuit, an active switch and a control module, wherein multiple data cables are formed in a display area of the substrate, the data driving circuit is used for driving the data cables, the active switch connects the data driving circuit and the data cables, and the control module is coupled to a control end of the active switch. When previous frame information is same with current frame information, the control module controls the active switch to be switched off, the data driving circuit is connected with the data cables through the active switch, signal transmission between the data driving circuit and the data cables can be effectively controlled, the output of the data driving circuit and actual input of the display panel are separated by using the active switch, selective refreshing effect of the display area of the substrate is achieved, and the power consumption of the display panel is further lowered.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] The display has many advantages such as thin body, power saving, no radiation, etc., and has been widely used. Most of the displays currently on the market are backlight displays, which include a display panel and a backlight module. The working principle of the display panel is to place liquid crystal molecules between two parallel substrates, and apply a driving voltage on the two substrates to control the rotation direction of the liquid crystal molecules, so as to refract light from the backlight module to generate images. [0003] Among them, Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has gradually occupied a dominant position in the display field due to its low power consumption, excellent picture quality, and high production yield. Similarly, a thin film transistor display includes a ...
