Problems solved by technology
Compared with IPS liquid crystal technology, VA liquid crystal technology has the advantages of higher production efficiency and lower manufacturing cost, but its optical properties have obvious defects in optical properties. LCD panel will have color shift phenomenon
[0003] At present, the way to improve color shift is to solve the problem of color shift by giving different driving voltages to the spatial sub-pixels in the display array or giving different driving voltages to adjacent sub-pixels in space. Pixels use the same transmission data line, and there is a capacitive resistance effect between this data line and other pixel-related electrodes, so if the data line is frequently switched between high and low voltages, the capacitive resistance effect will distort the high and low voltage signals and affect the display quality of the screen

Embodiment Construction
[0046] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0047] The main solution of the embodiment of the present invention is that, in the display panel, the display panel includes a plurality of pixel groups 01 arranged in an array, each pixel group 01 includes a first pixel unit, and the first pixel unit includes at least two first Sub-pixel; define the first sub-pixel in one of any two adjacent pixel groups 01 as the first target pixel 11, define the first sub-pixel in another of any two adjacent pixel groups 01 as the second Target pixel 12. Based on the above settings, the driving method of the display panel includes the following steps: acquiring the first initial driving data corresponding to the first target pixel 11, and acquiring the second initial driving data corresponding to the second target pixel 12; determining according to the first initial driving data ...

The invention discloses a driving method of a display panel. The method comprises the steps that first initial driving data corresponding to a first target pixel is acquired and displayed, and secondinitial driving data corresponding to a second target pixel is acquired and displayed; corresponding first high-voltage data is determined according to the first initial driving data, and corresponding first low-voltage data is determined according to the second initial driving data; first target high-voltage driving data corresponding to the first target pixel is determined according to the firsthigh-voltage data, and the first target low-voltage driving data corresponding to the second target pixel is determined according to the first low-voltage data; the first target pixel is driven by adopting the first target high-voltage driving data, and the second target pixel is driven by adopting the first target low-voltage driving data. The invention further discloses a driving device of thedisplay panel and a displayer. The driving method improves the color cast phenomenon of view angle, avoids that frequent switching between high voltage and low voltage causes signal distortion, and improves the image display quality.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a driving method of a display panel, a driving device of a display panel and a display. Background technique [0002] Most of the large-size LCD panels use negative VA (Vertical Alignment, wide viewing angle) liquid crystal or IPS (In-Panel Switching, in-plane switching) 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 its optical properties have obvious defects in optical properties. There will be a color shift phenomenon in the liquid crystal display panel. [0003] At present, the way to improve color shift is to solve the problem of color shift by giving different driving voltages to the spatial sub-pixels in the display array or giving different driving voltages to adjacent sub-pixels in space. Pixels use the same transmission data line,...
