Embodiment 1

[0038] In the driving method of the liquid crystal display provided by the embodiment of the present invention, the liquid crystal panel in the liquid crystal display is divided into a plurality of regions along the lateral direction, and each region includes a plurality of data lines.

[0039] Such as image 3 As shown, in each region, the data signals of sub-pixels in m columns are positive polarity, and the data signals of sub-pixels in n columns are negative polarity. That is, the potentials of the m data lines are positive polarity, and the potentials of the n data lines are negative polarity.

[0040] In this embodiment, the numbers of m and n can be adjusted according to the potential shift of the common electrode line. When the potential shift of the common electrode lines is negative, it is adjusted to be m>n, so that there are more data lines with positive polarity than data lines with negative polarity. When the potential shift of the common electrode lines is pos...

Embodiment 2

[0049] An embodiment of the present invention provides a liquid crystal display, including a liquid crystal panel, a potential detector and a data driver. The liquid crystal panel is divided into multiple regions along the lateral direction, and each region includes a plurality of data lines. The potential detector is used to detect the potential shift amount of the common electrode lines in the liquid crystal panel.

[0050] Data drivers are used to drive the data lines in each region, such as image 3 As shown, in each region, the data signals of the m columns of sub-pixels are of positive polarity, and the data signals of n columns of sub-pixels are of negative polarity. That is, the potentials of the m data lines are positive polarity, and the potentials of the n data lines are negative polarity.

[0051] In this embodiment, the quantities of m and n can be adjusted according to the potential deviation of the common electrode line detected by the potential detector. Whe...

Abstract

The invention discloses a liquid crystal display and a driving method thereof and belongs to the technical field of display, and a bad phenomenon of horizontal crosstalk can be eliminated. In the driving method of the liquid crystal display, the liquid crystal panel in the liquid crystal display is divided into multiple areas along a horizontal direction, and each of the areas comprises multiple lines. In each of the areas, the potentials of m data lines are positive potentials, and the potentials of n data lines are negative potentials. When the potential of a common electrode line is shifted to be a negative potential, m is larger than n. When the potential of a common electrode line is shifted to be a positive potential, m is smaller than n. The liquid crystal display and the driving method can be used for an array substrate made by a four mask plate patterning process.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display and a driving method thereof. Background technique [0002] With the development of display technology, a Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) has become the most common display device. [0003] Among them, crosstalk (Crosstalk) is a relatively common phenomenon in display defects of liquid crystal displays, and specifically refers to a phenomenon in which images in a certain area will affect images in other areas, resulting in poor display effects. According to different locations where the crosstalk occurs, it can be divided into vertical crosstalk (Vertical Crosstalk) and horizontal crosstalk (Horizontal Crosstalk). [0004] The causes of different types of crosstalk are also different. Usually, different driving methods will lead to crosstalk with different macroscopic performance. For example, linear horizontal crosstalk...
