Problems solved by technology
However, with the increase in the size of LCD panels, vertical or horizontal brightness unevenness is prone to appear on the boundary line of the chip-on-chip film. However, using the current technology to eliminate panel brightness unevenness, the edge of panel brightness unevenness is just not on the sampling point. Then the effect of the current solution to eliminate uneven brightness of the panel will be very poor, or even have no effect at all.

The invention provides a method for eliminating uneven panel brightness between horizontal or vertical substrates. The method comprises the following steps of setting a plurality of demarcation pointson the boundary of a plurality of substrates in a to-be-supplemented direction; photographing a panel so as to obtain the brightness values of a plurality of sampling points, wherein the plurality ofsampling points comprise the right-angle points of a plurality of rectangular areas of the panel and the plurality of demarcation points on the boundary of the plurality of substrates in the to-be-supplemented direction, and the plurality of demarcation points are arranged on the boundary to divide a plurality of pixels and obtain one demarcation point; outputting the brightness values of the plurality of right-angle points and the brightness values of the plurality of demarcation points. By adopting the method, the uneven brightness problem of the boundary panel of a substrate can be effectively solved, and the adaptation condition of a panel uneven brightness elimination mechanism for panels can be improved.
Description
technical field [0001] The present application relates to the field of liquid crystal display technology, and in particular to a method for eliminating uneven brightness of panels between horizontal or vertical substrates (for example: Chip On Film, COF for short). Background technique [0002] Due to the complex production process and difficult control of liquid crystal panels, it is easy to cause mura phenomenon (uneven brightness) during the production process, and bright or dark spots appear, that is, block-like traces caused by differences in display brightness in a certain area of the panel Phenomenon, reduce the quality level of the panel. In recent years, with the popularization of 4K and 2K TVs, the phenomenon of panel brightness unevenness has become more and more serious. Demura (eliminate panel brightness unevenness) technology has emerged as the times require. At present, in order to reduce the amount of compensation data, this technology adopts Set a plan fo...
