Problems solved by technology

Then the disadvantages of this current approach can also be imagined. If there is a display device with uneven light source (Mura) that can only be seen from 30% grayscale, then using this linear operation will not only fail to obtain a good compensation effect, but will It will adversely affect the low grayscale where the light source unevenness (Mura) cannot be seen originally.

Abstract

A method for generating an image compensation signal, a structure and a repair system (701): obtaining a central brightness value (S301, S401) of a display device (600) by means of an image capture device (105, 702); then setting a grayscale percentage value by means of a calculation module (103), and adjusting the brightness (S302, S402) of the display device (600) according to the grayscale percentage value; obtaining a brightness value (S303, S403) of the display device (600) by means of the image capture device (105, 702) according to the grayscale percentage value; obtaining a brightness difference value (S304, S404) by means of a brightness difference detecting module (101); and determining, by means of a difference determination module (102), whether the brightness difference value is smaller than a system default value; when the brightness difference value is smaller than the system default value, reducing the grayscale percentage value by means of the calculation module (103), and then comparing again; if the brightness difference value exceeds the system default value, obtaining a sample grayscale by means of a processing module (104).

Description

Technical field [0001] The present invention relates to the field of display, in particular to a method, structure and repair system for generating an image compensation signal. Background technique [0002] With the rapid development of the display technology industry, liquid crystal displays have become mainstream products in recent years. Driven by user demand and industry competition pressure, liquid crystal displays have the advantages of high resolution, high brightness, and no geometric distortion. At the same time, due to their small size, light weight and low power consumption, they are widely used in people’s daily use. In consumer electronics products, such as TVs, computers, mobile phones, tablets, etc. The flat display module is the main component of the liquid crystal display. Its manufacturing process is complicated and requires nearly a hundred processes. Therefore, various display defects will inevitably occur in the manufacturing process. These display defects ...
