Problems solved by technology

[0003] In the design of main and auxiliary pixels, the main pixels are often bright or dark, the overall display effect is not uniform, and the visual effect is not good enough, especially when the polarity of the data signal is reversed, the charging effect of each pixel will be affected. , it does not display well

Abstract

The invention discloses a driving method of a display panel and a display device, and the driving method comprises the steps: a scanning signal, a data signal and a common level signal of each pixel are output to a scanning line, a data line and a common line corresponding to the pixel, so as to drive the pixel; the common level signal takes one frame of the display panel as a period, and the level of the common level signal comprises a first common level and a second common level which are different in level value; corresponding to the current pixel, in the ath frame, the ending moment of the first common level is not later than the opening moment of the scanning line corresponding to the current pixel in the ath frame, and the ending moment of the second common level is not earlier than the closing moment of the scanning line corresponding to the current pixel in the ath frame; every two pixels form a group along the direction of the data line, the (2m-1)th pixel is a main pixel, the (2m)th pixel is an auxiliary pixel, and data signals of the main pixel and the auxiliary pixel are the same; a and m are positive integers; and by adjusting the driving signal, the problem of large visual angle color cast is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a method for driving a display panel and a display device Background technique [0002] Most of the current large-size LCD panels use negative VA (Vertical Alignment, vertical alignment) liquid crystal technology. VA-type liquid crystal technology has the advantages of high production efficiency and low manufacturing cost, but there are obvious defects in optical properties. In particular, large-size panels require larger viewing angles for commercial applications. The brightness of VA-type liquid crystal drivers saturates rapidly with voltage at large viewing angles, resulting in a serious deterioration in viewing angle image quality contrast and color shift compared to square-view image quality. Generally, VA-type liquid crystal technology solves the viewing angle deviation by dividing RGB (red, green, blue) sub-pixels into main / auxiliary sub-pixels, so that the brig...
