[0002] As a core component of large-size display solutions, modular LED displays are widely used in command and control centers, commercial advertising, stage performances, and many other fields. By arranging and splicing multiple independent display modules in a matrix, they achieve ultra-large sizes and high-resolution display effects that a single screen cannot match. In this system, the installation stability and splicing flatness of each display module directly determine the overall display quality and lifespan of the entire display. Therefore, how to achieve convenient and reliable installation and maintenance of display modules, and ensure their structural stability during long-term use, has become a key technical issue in this field.

[0003] Currently, the common installation method for dual-row video walls typically involves setting slots or screw holes in the support frame, and then using numerous screws to tighten and secure the display modules from the front or side of the screen during installation. This installation method has significant drawbacks: First, the installation process is cumbersome, requiring the tightening of screws on each display module, resulting in low operational efficiency. While using interlocking and positioning of the display modules only requires securing one or a few modules after splicing, the mutual compression between other display modules can easily cause them to squeeze together, potentially damaging them in severe cases. Therefore, a new splicing structure is urgently needed to solve the aforementioned problems of inconvenient installation and poor resistance to compression. Utility Model Content
