Today, Dejian took everyone to understand the structure of the outdoor full-color LED display steel structure and installation process 1. Screen back of the steel structure 2. Frame part:
3. Frame side, no edging 4. Installation box 5. Frame structure Figure 6. Front of the display For outdoor LED display full color screen, because it is used outdoors. Therefore, it must be treated differently from ordinary indoor LED display. Outdoor LED display installation requirements are not the same as ordinary indoor LED. In the installation must be done in detail. It is very likely to cause trouble.
Full color outdoor LED display installation six ideas:
1. Lightning protection devices are installed on display screens and buildings.
The main body of the display screen and the casing are well grounded, and the grounding resistance is less than 3 ohms, so that the large current caused by the lightning discharges in time; the display screen may be subject to strong electromagnetic attacks caused by lightning. Waterproof measures of the LED display itself and the joint between the screen and the building must be strictly waterproof and leakproof; the screen should have good drainage measures, and can be discharged smoothly in case of water accumulation; pay attention to waterproof and moisture proof. The display screen is installed outdoors, often exposed to the sun and rain, and the working environment is harsh. If the electronic device is wetted or severely dampened, it will cause a short circuit or even a fire, causing a malfunction or even a fire, resulting in loss;
3. The circuit chip selects and selects the industrial grade integrated circuit chip whose working temperature is between -40°C and 80°C, prevents the winter temperature from being too low to make the display screen unable to start.
4. Installation of ventilation equipment cooling, so that the internal temperature of the screen between -10 °C ~ 40 °C.
Axial fans are installed above the screen body to discharge heat; the display screen itself generates a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly, or even be burned, and the display system may not function properly. jobs;
5. Super high-brightness light-emitting diodes must be selected in order to ensure long-distance visibility in the presence of strong ambient light. Ultra-high-brightness light-emitting diodes must be used. Increased contrast, wide viewing area, wide line-of-sight requirements, and wide field of vision require large variations in ambient light. In particular, it may be exposed to direct sunlight.
6. The display medium adopts a new wide viewing angle tube with a wide viewing angle, pure color, consistent coordination, and an outer packaging life of over 100,000 hours. The outer packaging of the display medium is currently the most popular covered square tube, sealed with silicone, and no metal assembly; its exquisite appearance Beautiful, sturdy and durable, with features of protection against direct sunlight, dust, water, high temperature, and short circuits.
Advertising outdoor outdoor LED display installation considerations related to the future use of the product and safety, we must strictly treat it seriously. Dejian Optoelectronics completed a professional LED outdoor full-color display project from the very beginning of the professional steel frame design.

Anhydrous calcium chloride(CaCl2), also named White Powder Calcium Chloride Anhydrous, Anhydrous Calcium Chloride Powder Industrial Grade, Calcium Chloride Anhydrous Powder, is an ionic compound of calcium and chlorine. It is hygroscopic in nature and therefore must be kept in air tight container. It is highly soluble in water and it is a good source of calcium. It has a lot of applications such as dessicant, to increase the hardness in
water in swimming pool which reduces the erosion in concrete pools by le Charlie principle and common ion effect, food industry, medicines ,sterilization, freezing etc.
