Non-uniformity of luminance for big screen of LED flat panel display is one of problems affecting its display qualities, but existing widely. This paper analyzes the influences of luminance non-uniformity on LED display images, gives a plan on luminance uniformity correction based on CCD, and then proceeds correction algorithm of correction technology, at last conducts luminance non-uniformity correction for LED flat panel display from brightness datum of CCD image processing, which gives results and analysis before and after correcting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
