HBYLED's Led grille screen is waterproof and dust proof

LED display screen is a display screen used to display text, graphics, images, animation, market quotation, video, video signal and other information by controlling the display mode of semiconductor light-emitting diodes. With the continuous advancement of LED display technology, it can be seen in many public places such as shopping malls, theaters, bars, science and technology squares, exhibition halls, and stations in the city. Compared with indoor LED display, Winbond outdoor LED display is more susceptible to external environmental factors to affect the display effect. Then, in this case, outdoor LED display is equipped with protective equipment. . For example, in the face of outdoor dusty areas, the LED display needs to have a strong dust-proof function. In the face of rain water invasion and corrosion, it must have a waterproof function. In order to ensure that the outdoor LED display can display efficiently and stably continuously, it is necessary to add many protective devices such as dustproof, waterproof, anti-corrosion, lightning protection, windproof, moistureproof, antifreeze, and antistatic. According to the relevant regulations of the home standard, the protection of the outdoor LED large screen enclosure is divided into 3 levels, of which the A level is the lowest and the C level is the highest.

IP level is a professional term for the protection level of the display screen. The international protection standard for LED display screens is IP66, where IP66 means: dust tight (no dust is allowed to enter), strong water spray prevention (strong water spray in all directions of the housing has no harmful effects) . It can be seen that only in terms of dust and water resistance, the large LED screen assembled on site obviously has many defects and hidden dangers. According to the requirements of the C-level standard, it is very necessary for the display unit module of Huabangying's large LED screen to adopt a closed type. Unit box structure, and use packaging insulating materials to potting the surface and surrounding of the circuit board, thereby maximizing the isolation of the entire circuit board and the LED light-emitting tube from the external environment, and avoiding various corrosive substances from harming the screen.

In addition to waterproof and dustproof, installing a light-proof grille cover for the display screen can also play a good protective effect. Each LED circuit module should be equipped with a light-shielding (light-proof) grille cover. The grid cover is composed of a substrate and a grid. The substrate has LED positioning holes corresponding to the LED pixel units on the LED circuit module. The grid is located on the upper edge of the LED positioning hole and forms an angle θ with the substrate. In this way, when strong light is irradiated from this direction, it can effectively reduce its interference to the LED pixels and reduce the impact of reflection, thereby increasing the contrast of the large screen and improving the display effect. By installing protective devices for outdoor LED display screens, it can better adapt to various harsh outdoor natural environments. While extending the service life of the display screen, it also improves its display effect.
