LED display screens are usually composed of several modules arranged in a certain pattern and fixed at a suitable height to display various information such as text, images, videos, and video signals. The bottom shell of the module needs to be made of a variety of materials to make it light and strong.

[0003] After searching, the patent number CN206003455U is a utility model of a new die-cast aluminum alloy LED display module bottom shell, which is composed of a base, reinforcing ribs, beams, columns and panels. Through research and analysis, it is found that although the bottom shell has the advantages of high heat dissipation and extended service life, it still has the following disadvantages to a certain extent;

[0004] For example, aluminum alloy plates have poor corrosion resistance and heat dissipation properties. They are affected by external temperature changes and come into contact with liquids, which can cause moisture corrosion and wear. During use, they cannot efficiently dissipate the heat generated during operation, and can easily affect the stable operation of the LED display and limit its service life. There is no supporting structure on the aluminum alloy plate, which can easily cause breakage and damage due to external forces. In order to solve the above technical problems, it is necessary for us to design a high-strength aluminum alloy plate for LED display screens to solve the above problems. Utility Model Content
