How to ensure the quality of outdoor large screen installation?
1. Ultra-high-brightness LEDs must be used in order to ensure long-distance visibility under strong ambient light conditions. Ultra-high-brightness LEDs must be used; contrast is increased. The audience is wide, the line of sight is far, the field of view is wide, and the ambient light varies greatly. In particular, it may be exposed to direct sunlight.
2. The display medium adopts a new wide viewing angle tube with wide viewing angle, pure color and consistent coordination. The outer packaging of the display medium with a life span of more than 100,000 hours is currently the most popular square-shaped cylinder with a cover, silicone seal, and metal-free assembly; Beautiful, sturdy and durable, with anti-sunlight direct, dustproof, waterproof, high temperature, anti-circuit short circuit five features.
3. Circuit Chip Selection Industrial-grade integrated circuit chips with an operating temperature between -40 ° C and 80 ° C are selected to prevent the display from failing to start when the temperature is too low in winter.
4. Full-color LED display and lightning protection device installed on the building.
The main body and the outer casing of the display are well grounded, the grounding resistance is less than 3 ohms, and the large current caused by lightning is discharged in time; the display may be attacked by strong electric current caused by lightning.
5. Waterproof measures for the full-color LED display itself The combination of the screen body and the screen body and the building must be strictly waterproof and leak-proof; the screen body should have good drainage measures, and the water can be discharged smoothly once the water accumulation occurs; pay attention to waterproof and moisture-proof. The LED display is installed outdoors, often exposed to the sun and rain, the wind blows the dust cover, and the working environment is bad. If the electronic equipment is wet or seriously damp, it may cause a short circuit or even a fire, causing malfunction or even fire, resulting in loss;
6. Install the ventilation equipment to cool down, so that the internal temperature of the screen is between -10 °C and 40 °C.
Raw Material Of Other Chemicals
These materials are raw materials for different chemicals. One of them is possible to be used in many chemicals or fields. Different materials are also possible to used for the same finished material.
It is basic material for many fields, such as pharma, chemical, dying, washing industry, and manufacture industry. Some are powder, some granule, some flake, some crystalline.
It is identified by purity and granule/block size, purity is the main identified method. It is used in different products as per its size.
