Abstract

The invention discloses a display panel, a display device and a driving method. The display panel includes a substrate, a sub-pixel array, and a plurality of data lines; when the plurality of data lines input a first voltage data signal and a second voltage data signal to a plurality of sub-pixels in the sub-pixel array, the input voltage of the first voltage data signal The sub-pixels and the sub-pixels input with the second voltage data signal are alternately arranged, and among the multiple sub-pixels of the same color in the same row, the sub-pixels input with the first voltage data signal of positive polarity and the first voltage data signal of negative polarity are input The number of sub-pixels is the same, and the polarities of the data signals of multiple sub-pixels in the same column are the same. The display panel can improve the large-size display panel's large viewing angle deviation problem, and can also avoid the color deviation of the output picture of the display panel at the same time, thereby improving the quality of the output picture of the display panel.

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...
