Abstract

The invention relates to the technical field of LED display, and specifically discloses a splicing bright and dark line adjustment system for an LED display screen based on two-dimensional graphic coding. The system uses the two-dimensional graphic coding to realize fast positioning of the bright and dark lines of a splicing gap, accurately identifies the gap width by the computer graphic recognition technology and calculates an adjustment coefficient of a corresponding edge pixel point, thereby preventing the occurrence of inconsistent brightness of the LED pixel points from causing the adjustment error of the bright and dark lines. The system mainly comprises a graphic coding module, an image acquisition module, a peripheral processing module and an LED display control module. The codingmodule is configured to perform two-dimensional graphic coding of the splicing gap of the LED display. The image acquisition module is configured to acquire each the imaging information of each splicing gap and upload the imaging information to a server. The processing module is configured to identify the gap imaging information, and calculate a bright and dark line adjustment coefficient. The LED display control module is configured to output the bright and dark line adjustment coefficient to the LED pixels at the splicing gaps of the LED display screen, thereby realizing the adjustment of the bright and dark lines at the splicing gap of the LED display.

Description

Technical field [0001] The invention relates to the field of LED display technology, in particular to a LED display screen splicing bright and dark line adjustment system based on two-dimensional graphic coding. Background technique [0002] The LED display is made up of several modules. Due to the limitation of machining accuracy and assembly accuracy during the splicing process, there may be gaps between the LED pixels on the edges of adjacent modules at the splicing of modules. The phenomenon of inconsistency is the occurrence of stitching gaps, which affects the display quality mainly as bright or dark lines appear when displaying low-frequency images, and its own geometric misalignment is not easy to be noticed. When the pixel center distance of the LED display becomes smaller, this problem is particularly prominent, which seriously affects the display quality. Therefore, it is very important to find a way to solve the splicing bright and dark lines of the LED display. [00...
