Abstract

The invention discloses a liquid crystal display panel and a driving method thereof. The method comprises the steps that: when the display image of a pixel unit is switched from a first brightness image to a second brightness image, a first driving voltage V1 is input to a pixel electrode of the pixel unit at a first frame of the second brightness image, and a first common voltage Vcom1 is input to a common electrode of the pixel unit, wherein the phase of the first driving voltage V1 is opposite to the phase of the first common voltage Vcom1, and the absolute value of the voltage difference between the first driving voltage V1 and the first common voltage Vcom1 is an over-driving voltage value needed by finishing the switching from the first brightness image to the second brightness image in the responding time of one frame, so that each pixel unit in the liquid crystal display panel is enabled to finish the switching from the first brightness image to the second brightness image in the responding time of one frame. Thus, a streaking phenomenon of the liquid crystal display panel in the prior art is prevented, and the display quality of the liquid crystal display panel is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and a driving method thereof. Background technique [0002] The response time of a liquid crystal display panel refers to the time required for its liquid crystal molecules to switch from one angle to another, and the twisting speed of the liquid crystal molecules is determined by the voltage difference applied to the two ends of the liquid crystal molecules. When the voltage difference applied across the liquid crystal molecules is small, the twisting speed of the liquid crystal molecules is small, and the response time of the liquid crystal display panel is also long. [0003] With the development of display technology, people have higher and higher requirements for the frame frequency of the liquid crystal display panel, and accordingly, the response time required for each frame is required to be shorter and shorter. However, the ...
