Problems solved by technology

However, because it is based on optical imaging information, it is difficult to require the brightness of all LED lights to be consistent, and there may still be certain errors
Moreover, it needs to be displayed on the full screen, and the module is used as a unit for regional correction, which still takes a long time.

Embodiment Construction

[0030] The invention provides a method and system for adjusting bright and dark lines of splicing LED display screens, which are used for adjusting bright and dark lines existing between adjacent LED display modules during the splicing process of LED display screens.

[0031] According to the first embodiment of the present invention, referring to the attached figure 1 , providing a method for adjusting splicing bright and dark lines of an LED display, including steps S11, S12, S13 and S14, specifically as follows:

[0032] S11: Encoding and displaying a two-dimensional graphic on the splicing gap of the LED display.

[0033] to attach figure 2 Take the 4 LED display modules in the example as an example, there is a side formed by LED pixels outside the splicing joint between the module and the module, each side corresponds to a number, and a special two-dimensional code is set at both ends of each side , here the 5 pixels at the corners of each module together form a cross ...

Abstract

The present invention discloses a method and system for adjusting bright and dark lines due to splicing of a LED display screen. The method includes the steps as follows: S11. performing a two-dimensional image coding operation for splicing apertures of the LED display screen, and performing display; S12. acquiring imaging information of each aperture code, and uploading the imaging information to a server; S13. recognizing the imaging information of the aperture by utilizing an image recognition technology, and calculating an adjusting coefficient of bright and dark lines; and S14. outputting the adjusting coefficient to LED pixel points of the splicing apertures of the LED display screen, and thereby realizing an adjustment for the bright and dark lines in the splicing apertures of the LED display screen. The system includes: an image coding module, an image acquiring module, a periphery processing module, and an LED display screen control module. The method and system can quickly position the bright and dark lines in the splicing apertures by utilizing two-dimensional image coding, preciously recognize an aperture width through a computer image recognition technology, and calculate the adjusting coefficient of the corresponding edge pixel points.

Description

technical field [0001] The invention relates to the technical field of LED display, in particular to an adjustment method and system for splicing bright and dark lines of an LED display screen. Background technique [0002] The LED display screen is spliced ​​by several modules. During the splicing process, due to the limitations of machining accuracy, assembly accuracy and other technological reasons, there may be gaps between the LED pixels on the edge of adjacent modules at the splicing point of the module. The phenomenon of inconsistency, that is, the occurrence of splicing gaps, the impact on display quality is mainly manifested in the appearance of bright or dark lines when displaying low-frequency images, and its own geometric misalignment is not easy to detect. This problem is particularly prominent when the pixel center distance of the LED display becomes smaller, which seriously affects the display quality. Therefore, it is very important to find a way to solve th...
