Problems solved by technology
And when the ambient temperature changes, or when the vehicle-mounted product generates a lot of heat, the overall temperature of the liquid crystal display panel becomes higher, resulting in changes in the characteristics of the liquid crystal display panel.
At this time, subject to the V COM The LCD panel driven by voltage is no longer in the state of minimum flickering degree. When the situation is serious, the LCD panel will appear obvious flickering phenomenon, which will reduce the user's viewing effect

The present invention discloses a liquid crystal display panel and a driving method thereof, belonging to the field of display technique. According to the invention, the liquid crystal display panel has a good display effect even in the condition of temperature variation. The driving method includes the steps as follows: detecting a temperature of the liquid crystal display panel in real time; acquiring a common voltage corresponding to the current temperature based on a pre-set relationship between the temperature and the common voltage according to the temperature of the liquid crystal display panel; and driving the liquid crystal display panel by utilizing the acquired common voltage. The liquid crystal display panel and the driving method can be used for display devices such as liquid crystal television set, liquid crystal displayer, mobile phone, tablet personal computer and the like.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and a driving method thereof. Background technique [0002] With the development of liquid crystal display (Liquid Crystal Display, LCD for short) technology, people have higher and higher requirements for the definition of the LCD, in other words, the resolution requirements for the liquid crystal display are also higher and higher. At the same time, people's requirements for the quality of picture display are getting higher and higher. Due to the characteristics of the liquid crystal display panel, when the ambient temperature changes greatly, the flickering degree of the liquid crystal display panel will also change. In the case of vehicle-mounted products and industrial control products, the flickering degree of the liquid crystal display panel will be more pronounced. as obvious. [0003] Specifically, because each LCD panel leaves the facto...
