Abstract

The invention discloses a display panel, a display device and a driving method. The display panel comprises a substrate, a subpixel array and multiple data lines. When the data lines input first voltage data signals and second voltage data signals into the subpixel array, subpixels inputting the first voltage data signals and subpixels inputting the second voltage data signals are alternately arranged, and in the subpixels with same color and in a same row, number of the subpixels inputting the first voltage data signals with positive polarity and number the subpixels inputting the first voltage data signals with negative polarity are equal. The problem of large-view-angle color offset of large-size display panels can be improved, and color offset of pictures output by the display panel can be avoided, so that quality of the pictures output by 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...
