Description

Waterproof module of LED transparent screen

Technical Field

The invention relates to the technical field of transparent LED screen boxes, in particular to a waterproof module of an LED transparent screen.

Background

At present, various LED transparent screens in the market can achieve a light and transparent display effect. High pass ultralight, thin, most products are non-closed unit module, reach light, thin, the characteristics of penetrating, the structural feature of many adoption is: the micro-frame, the light bar fixing structure and the light bar PCB are arranged, the LED light bar and the lamp panel are exposed outside, and the transparent advantage of the transparent LED display screen can be well presented. Still some products adopt the panel that increases transparent material around the unit module structure as the protection, can prevent that the lamp pearl from being knocked down, also can prevent that a most foreign matter and dust from getting into, have possessed certain protection level, generally are not higher than IP 42's protection level. Therefore, the application of the transparent LED display screen can only be temporarily applied indoors or outdoors in rainy days. However, with the development of market demands, for example, in the aspect of dance beauty deduction, many activities need to be carried out outdoors, the weather factor becomes the biggest obstacle to the transparent display screens without high-level protection at present, and the outdoor activities cannot apply the novel LED transparent display screens to dance beauty sites at all. Therefore, the transparent LED display screen without waterproof function in the current market has great market limitation in the market. A solution for a transparent LED display screen with a high IP level protection level becomes very important. But as a transparent LED display screen, it is difficult to achieve high-grade water resistance. Although the traditional outdoor LED display screen technology is mature, the traditional outdoor waterproof LED display screen technology cannot be applied to the transparent display screen because the important characteristics of the transparent display screen are transparent and attractive, and the traditional outdoor waterproof product solution basically adopts glue filling sealing and sealing ring structure sealing, so that the transparent display screen cannot be applied, and the transparent display screen can be changed into a non-transparent display screen because the solutions can all make the transparent display screen into the non-transparent display screen. The product of some manufacturers adopts a so-called nano coating technology, a nano waterproof coating is added on the circuit board, but the coating technology still cannot achieve the real waterproof effect for the LED display screen, many manufacturers adopt the scheme and cannot really succeed in the testing process, the coating adopting chemical substances has a certain protection function, but when the LED display screen is used outdoors, the environment is quite complex, for example, acid and alkali harmful substances and sun are irradiated for many times, and the waterproof effect of the transparent LED display screen can not be guaranteed by the coating.
