Embodiments of the invention disclose a liquid crystal display panel and a driving method thereof and a display device. The driving period of the liquid crystal display panel comprises a display stageand a non-display stage, wherein the non-display stage comprises a heating stage; the driving method comprises the following steps of applying a common voltage signal to a common electrode of the liquid crystal display panel in the display stage; and in the heating stage, applying a heating signal to the common electrode of the liquid crystal display panel. According to the embodiments of the invention, the heating signal is applied to the common electrode of the liquid crystal display panel in the heating stage, and the heat generated by the common electrode can directly act on liquid crystal molecules in the liquid crystal display panel, so that the purpose of quickly starting the liquid crystal display panel under a low-temperature environment is achieved, the display quality of the liquid crystal display device is guaranteed, and the problems that the liquid crystal display screen is low in heating efficiency and low in speed when the liquid crystal display screen works at a low temperature are solved.
Description
technical field [0001] Embodiments of the present invention relate to organic light-emitting display technologies, and in particular, to a method for driving a liquid crystal display panel, a liquid crystal display panel, and a display device. Background technique [0002] Due to its low power consumption, high definition, long life, small size, light weight and other characteristics, liquid crystal displays are widely used in various devices that need to realize display. [0003] When the temperature is low, the liquid crystal material will become viscous, the response speed will slow down after power-on, and the dynamic image will appear trailing or even unable to be displayed; when the temperature is low, the liquid crystal state of the liquid crystal material will disappear, and the liquid crystal material will become crystal , the screen cannot be displayed. Therefore, it is necessary to heat the liquid crystal display to control the temperature within a reasonable ran...
