Problems solved by technology

However, Dot Inversion has the problem of large drive power consumption and abnormal display of image quality, and Z-Inversion also has the problem of high power consumption in some screens.
So cannot replace ColumnInversion
Column Inversion has the advantages of low power consumption and strong data line driving force, but it cannot suppress vertical crosstalk
Therefore, due to the limitations of the driving mode, issues such as crosstalk set a high threshold for panel design

Abstract

The invention provides a display panel, a driving method thereof, and a display device, belongs to the display technology field, and helps to solve the problems that a conventional display panel is high in power consumption and cannot display uniformly. The display panel comprises multiple grid lines and multiple data lines, the grid lines and the data lines crossing each other. A pixel unit is defined in the intersect position of each grid line and one corresponding data line. The multiple pixel units are divided into multiple pixel groups. Every N adjacent pixel units in the same row serve as one pixel group, N being an integer greater than or equal to 1. Each row of grid lines is used for driving the A pixel group (A being an even number) of the pixel units above the grid lines, and driving the B pixel group (B being an odd number) of the pixel units below the grid lines. Or, each row of grid lines is used for driving the B pixel group (B being an odd number) of the pixel units above the grid lines, and driving the A pixel group (A being an even number) of the pixel units below the grid lines.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel, a driving method thereof, and a display device. Background technique [0002] In a traditional liquid crystal display device (TFT-LCD), the driving methods of the liquid crystal display panel include Column Inversion (column inversion), Dot Inversion (dot inversion), Z-Inversion and the like. Among them, Dot Inversion and Z-inversion mainly use sub pixel (or multiple sub pixel) to flip the data line or Z-shaped wiring to achieve adjacent voltage polarity difference to improve visible crosstalk. However, Dot Inversion has the problem of high drive power consumption and is prone to display abnormal image quality. Z-Inversion also has the problem of high power consumption in some screens. So cannot replace ColumnInversion. Column Inversion has the advantages of low power consumption and strong data line driving force, but it cannot suppress vertical c...
