Abstract

The invention discloses a display panel, a display device and a driving method. The display panel is composed of a substrate, a sub pixel array, and a plurality of data lines. When the plurality of data lines input first voltage data signals and second voltage data signals into a plurality of sub pixels in the sub pixel array, the sub pixels with the first voltage data signals inputted and the subpixels with the second voltage data signals inputted are arranged alternately; and among the multiple sub pixels with the same colors at the same rows, the number of the sub pixels with positive first voltage data signals inputted is the same as the number of the sub pixels with the negative first voltage data signals inputted and the polarities of the data signals of the multiple sub pixels at the same columns are identical with each other. According to the display panel disclosed by the invention, the large-view-angle color cast problem of the large-size display panel can be improved; and the color deviation problem of the outputted picture of the display panel can be avoided, so that the quality of the outputted picture of the display panel is 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 appear that the number of sub-pixels of the positive high-voltage signal does not match the number of sub-pixels of the negative high-voltage signal, so that t...
