Abstract

The invention discloses a display panel, a display device and a driving method. The display panel comprises a substrate, a sub-pixel array and a data line. In a plurality of sub pixels on the same line, the sub pixels for inputting first voltage data signals and the sub pixels for inputting second voltage data signals are arrayed alternately. The two sub pixels, on the same column, in a same pixelunit input the first voltage data signals and the second voltage data signals respectively. In the two adjacent pixel units on the same column, the sub pixels with same colors input the first voltagedata signals and the second voltage data signals respectively. In the sub pixels with the same colors and on the same line, the number of the sub pixels for inputting positive-polarity first voltagedata signals is the same as the number of the sub pixels for inputting negative-polarity first voltage data signals. The polarity driving modes adopted by the two adjacent pixel units on the same column are opposite. By the display panel, large-view color cast of large-size display panels can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a driving method. Background technique [0002] Vertically aligned (VA) mode liquid crystal display panels are applied to large-sized liquid crystal displays due to advantages such as high production efficiency and low production cost. In order to improve the large viewing angle deviation problem of large-size liquid crystal displays, in the existing liquid crystal display, the data signal corresponding to the original image is spatially divided into high-voltage signal and low-voltage signal, and the high-voltage signal and low-voltage signal are respectively Input to different pixel units. [0003] However, in the liquid crystal display using the above method, it is easy to have a mismatch between the number of positive sub-pixel units and the number of negative sub-pixel units in the pixel unit of the high voltage signal, which m...
