Abstract

The invention discloses a display panel driving circuit and method. The display panel driving circuit comprises a time sequence controller, a data driving circuit and a scanning driving circuit; the display panel is a display panel with a zigzag structure; the polarities of the gray scale voltage signals on the data line in front and back adjacent frames of images are opposite; polarity of each row of sub-pixels in each frame of image is reversed at an interval of every m columns; the gray scale voltage signals of two adjacent data lines in the m columns of data lines correspond to a first signal and a second signal with opposite polarities, wherein the first signal is greater than a positive reference gray scale voltage signal, the second signal is less than a negative gray scale reference voltage signal, m is greater than or equal to 2, m is an even number, common electrode voltages on each row of sub-pixels are mutually offset, and the common electrode voltage offset is zero, so that the image flickering phenomenon of the display panel is improved.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a display panel driving circuit and method. Background technique [0002] The statements herein merely provide background information related to the present application and do not necessarily constitute prior art. [0003] With the development of the liquid crystal display field, higher image quality has become the main indicator of major display manufacturers, and chromaticity and viewing angle are an important indicator of image quality. [0004] The combination of flip-pixel technology and wide viewing angle technology is usually used to improve image quality. The flip-pixel architecture is also called zigzag (zigzag) architecture. The advantage of this architecture is that the polarity of each data line naixujuhs is the same. That is, the column inversion mode can be used to achieve dot inversion to achieve the purpose of reducing power consumption. Each posit...
