Description

Technical Field

[0001] The utility model relates to the technical field of display screen covers, in particular to a front cover of an outdoor LED display screen. Background Art

[0002] The front cover design of the LED display needs to consider multiple factors, including heat dissipation, protection level, and aesthetic appearance. First of all, heat dissipation is a very important factor. Since the LED display has high brightness and generates a lot of heat, if the heat dissipation is not good, it will cause the display to overheat and affect its service life. Therefore, the front cover design needs to fully consider the heat dissipation problem. You can use a large area heat sink, increase the number of fans, etc. to improve the heat dissipation effect. Secondly, the protection level is also a factor that needs to be considered. Since LED displays are usually installed outdoors and need to withstand environmental factors such as wind, rain, and dust, the front cover design needs to have a high protection level to effectively protect the internal LED lamp beads and other components from damage.

[0003] Common display screen front covers are generally connected to the mounting frame by multiple sets of bolts during installation. However, this method has a large number of bolts and is prone to thread stripping after long-term outdoor use, which in turn affects the disassembly and assembly of the front cover. In addition, the screw connection method is prone to damage or cracking of the front cover edge due to external force, which cannot meet the working requirements of the front cover. Therefore, an outdoor LED display screen front cover is proposed. Utility Model Content
