[0002]
At present, most of the large display screens are composed of splicing LED display modules, and the splicing too far or too close between the LED display modules will cause the distance between the lamp beads at the seam to be too large or too small, forming obvious dark seams or bright lines

Embodiment Construction
[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0044]It should be noted that when a component is said to be "mounted on" another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly fixed to the other component or there ...

The invention relates to an LED display screen splicing seam compensation method and an LED display screen. The LED display screen splicing seam compensation method comprises the steps that S1, M * N LED display modules and a box body used for installing the LED display modules are provided, and the tolerance upper limit of the machining size of the LED display modules is larger than the tolerance upper limit of the box body; S2, the LED display modules are installed in the box body; and S3, bright lines at the splicing positions of the adjacent LED display modules are eliminated. According to the LED display screen splicing seam compensation method, firstly, the machining dimensions of the LED display modules and the box body are designed, so that the tolerance upper limit of the machining size of the LED display modules is larger than the tolerance upper limit of the box body, and therefore it is guaranteed that no gap exists between the adjacent LED display modules after the LED display modules are installed on the box body, and no blind seam is generated; after the LED display modules are installed on the box body, the bright lines at the splicing positions of the adjacent LED display modules are eliminated, the brightness of splicing seams is kept consistent with that of the whole LED display screen, and the purpose of optimizing the display effect of the splicing seams of the LED display screen is achieved.
Description
technical field [0001] The invention relates to the technical field of LED display screens, in particular to an LED display screen seam compensation method and an LED display screen. Background technique [0002] At present, most of the large display screens are composed of LED display modules, but too far or too close to each other will cause the distance between the lamp beads at the seam to be too large or too small, forming obvious dark seams or bright lines. Whether it is a dark seam or a bright seam, it has a significant impact on the display effect of the large display screen. Contents of the invention [0003] Based on this, it is necessary to address the above problems and provide a LED display splicing seam compensation method and an LED display. The LED display splicing seam compensation method can improve the display effect of the LED display by eliminating dark seams through splicing. [0004] The present invention firstly provides a LED display splicing seam...
