Problems solved by technology
[0002] Most of the existing large-size liquid crystal display panels use negative VA liquid crystal or IPS liquid crystal technology. Compared with IPS liquid crystal technology, VA liquid crystal technology has the advantages of higher production efficiency and lower manufacturing cost, but compared with IPS liquid crystal technology in terms of optical properties IPS liquid crystal technology has obvious defects in optical properties, especially large-size panels require a larger viewing angle for commercial applications, and VA-type liquid crystal drivers often fail to meet market application requirements in terms of viewing angles, which affects the VA-type liquid crystal technology. to promote
[0003] Generally, VA-type liquid crystal technology solves the problem of viewing angle deviation by dividing the primary colors of RGB into primary and secondary pixels, and giving different driving voltages to the primary and secondary pixels in space to solve the defect of viewing angle deviation. Such pixel design often needs to be redesigned. Sub-pixels are driven by metal traces or thin-film transistor elements, resulting in the sacrifice of the light-transmitting opening area, affecting the panel transmittance, and directly increasing the cost of the backlight module

Disclosed are a driving method and a driving device for driving a display apparatus, as well as a display apparatus. The driving method includes: obtaining a first voltage driving signal and a second voltage driving signal of a sub-pixel of each of a plurality of pixels in an image; dividing each of all the sub pixels into two parts that are adjacent to each other with a stagger interval; and further dividing each of the parts into second luminescence signal values with the first luminescence signal values, where the second luminescence signal values and first luminescence signal values are adjacent to each other with a stagger interval, so as to control a display of the corresponding pixel.
