Abstract
This paper focuses on the LED display screen lamp dot luminance deviation detecting technology. By using mathematical morphological algorithm, the problems of how to eliminate the false lamp dot, how to acquire the center of lamp dot, and acquire the relative brightness value of the center position on LED lamp dot are solved. Basic data for the LED brightness correction is also provided in the paper.
