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 plurality of data lines, wherein the sub-pixel array includes a plurality of pixel groups. Sub-pixels for inputting first voltage data signals and sub-pixels for inputting second voltage data signal are alternately arranged, in the multiple sub-pixels ofthe same color in the same row, the number of sub-pixels for inputting positive first voltage data signals and the number of sub-pixels for inputting negative first voltage data signals are the same,and polarity driving modes used by two adjacent pixel groups in the same column are opposite. According to the display panel, a large view angle color offset problem of a large-sized display panel canbe improved, at the same time, a color deviation caused by difference of the number of the sub-pixels for inputting the positive first voltage data signals and the number of sub-pixels for inputtingthe negative first voltage data signals can be avoided, and the quality of an outputted picture 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] Vertical alignment (VA) mode liquid crystal display panels are applied to large-size liquid crystal displays due to the advantages of high production efficiency and low production cost. In order to improve the large-size liquid crystal display's large visual angle problem, in the existing liquid crystal display, the data signal corresponding to the original image is spatially divided into a high voltage signal and a low voltage signal, and the high voltage signal and the low voltage signal are respectively Input to different pixel units. [0003] However, in the liquid crystal display using the above method, the number of sub-pixels with positive high-voltage signals and the number of sub-pixels with negative high-voltage signals are prone to mismatch, making the common electrode voltage easi...
