Utilize magnetic force for quick adsorption and positioning, initially fixing the cover. Then, the slot 102 at the lower end of the main frame 1 engages with the display screen's snap-fit ​​structure to further secure the connection between the cover and the display screen. This double-fixing method ensures the cover is firmly installed and not easily detached. During LED display operation, a large amount of heat is generated. The heat sinks 2 around the main frame 1 function, their large surface area quickly absorbing the heat emitted by the display screen and dissipating it into the surrounding air, accelerating air convection and effectively reducing the internal temperature of the display screen. This ensures the LED display screen operates stably in a suitable temperature environment, extending its lifespan. The multi-layered structure of the cover body 3 provides protection for the display screen. The inner layer 301's E... When the display screen is subjected to external collisions or vibrations, the VA material can buffer the impact force and reduce the impact of vibrations on the internal components of the display screen, thus playing a shock-absorbing and protective role. The base layer 302, with its high strength and toughness, resists external pressure and collisions, protecting the display screen from physical damage. The connecting layer 303 enhances the bonding force between the layers, ensuring the stability of the mask structure. The acrylic material of the outer layer 304 has good light transmittance and does not affect the normal display of the LED display screen. At the same time, its smooth surface is easy to clean, preventing dust and stains from adhering and affecting the display effect. The sealing silicone 103 fills the inner surface of the connecting shell 101, tightly adhering to the display screen to form a sealed space, effectively blocking external dust, moisture and corrosive gases from entering the display screen, avoiding these substances from damaging the display screen components, ensuring the normal working environment of the display screen, and improving the reliability and stability of the display screen.
