Problems solved by technology

[0002] Large-size LCD panels mostly use negative vertical alignment (Vertical Alignment, VA) liquid crystal technology or in-plane switching (In-Plane Switching, IPS) liquid crystal technology. Compared with IPS liquid crystal technology, VA liquid crystal technology has higher production efficiency And the advantages of low manufacturing cost, but compared with IPS liquid crystal technology in terms of optical properties, there are more obvious defects in optical properties, especially for large-scale panels that require a larger viewing angle for commercial applications, that is, there are more serious color shifts

Abstract

The invention discloses a driving method and driving system of a display panel. The driving method comprises the following steps: previously dividing sub-pixel signals corresponding to to-be-judged sub-pixels into multiple signal judgment intervals; counting the proportion of the amount of the sub-pixel signals in each signal judgment interval in the total amount of the sub-pixel signals; respectively judging whether a corresponding preset standard proportional value is satisfied, and searching the maximum proportion interval; dividing to-be-judged sub-pixels into multiple cycles by taking 2nadjacent to-be-judged sub-pixels with the same color as one cycle according to the maximum proportion interval, and respectively determining first adjusting way sub-pixels and second adjusting way sub-pixels in every cycle by taking the to-be-judged sub-pixel group as a unit; driving the first sub-pixels and the second sub-pixels corresponding to the first adjusting way sub-pixels through a firstadjusting way; and driving the first sub-pixels and the second sub-pixels corresponding to the second adjusting way sub-pixels through a second adjusting way.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving method and a driving system of a display panel. Background technique [0002] Large-size LCD panels mostly use negative vertical alignment (Vertical Alignment, VA) liquid crystal technology or in-plane switching (In-Plane Switching, IPS) liquid crystal technology. Compared with IPS liquid crystal technology, VA liquid crystal technology has higher production efficiency And the advantages of low manufacturing cost, but compared with IPS liquid crystal technology in terms of optical properties, there are more obvious defects in optical properties, especially in commercial applications of large-size panels that require a larger viewing angle, that is, there is a relatively serious color shift. [0003] Therefore, how to improve the color shift has become an important research topic for those skilled in the art. Contents of the invention [0004] The object of t...
