Abstract

The invention provides a liquid crystal display panel and a driving method and device thereof, belongs to the technical field of display, which can at least partially solve the problem of display defects caused by an existing liquid crystal display panel driving method. The invention discloses a driving method of a liquid crystal display panel. According to the method, driving signals are provided for all sub-pixels in each frame through data lines, the polarities of the driving signals of the sub-pixels connected with the same data line in each frame are the same, and the method comprises the steps that in the first stage, an even number of frames are included, and the polarities of the driving signals of any sub-pixel in any two adjacent frames are opposite; In the second stage, an evennumber of frames are included, and the driving signal polarities of any two adjacent frames of any sub-pixel are opposite; Wherein the polarities of any sub-pixel in the last frame of the first stageand the first frame of the second stage are the same; In the first frame of the second stage, the drive signal of at least part of the sub-pixels is determined by the original signals of the sub-pixels in the last frame of the first stage and in the first frame of the second stage.

Description

Technical field [0001] The invention belongs to the field of display technology, and specifically relates to a liquid crystal display panel and a driving method and device thereof. Background technique [0002] In order to ensure the display effect (such as avoiding defects such as line afterimages), the prior art liquid crystal display panels generally use POL inversion technology when using column inversion or frame inversion driving methods: an even number of frames is a cycle (For example, the period length is 28s), the signal polarity of the same sub-pixel in adjacent frames in each period is opposite (for example, the driving mode of column inversion or frame inversion in each period), and in the adjacent In a cycle, any sub-pixel in the last frame of the previous cycle has the same signal polarity as that of the sub-pixel in the next cycle. For example, in the previous cycle, the signal polarity of the same sub-pixel in consecutive frames is positive, negative, positive N...
