Outdoor LED Display Design and Installation

Outdoor LED display design and installation issues,

In order to keep the outdoor led display in normal operation for a long period of time, the engineers will examine many possible problems during design and installation, such as the following:

The main problems of outdoor screens are as follows:

(1) The display screen is installed outdoors, often exposed to the sun, rain, wind, cover and working environment. 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;

(2) The display may be subject to strong magnetic and magnetic shocks caused by lightning;

(3) The temperature of the environment changes greatly. When the display screen works, it must generate 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 work properly.

(4) The audience is wide, the line-of-sight is far away, and the field of vision is wide; the ambient light changes greatly, and in particular it may be exposed to direct sunlight.

For the above special requirements, the outdoor display must be:

(1) The screen body and the joint between the screen body and the building must be strictly waterproof and leakproof; the screen body must have good drainage measures and can be smoothly discharged once the water accumulation occurs;

(2) Install lightning protection devices 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;

(3) Install the ventilation equipment to reduce the temperature, so that the internal temperature of the screen is between -10 °C ~ 40 °C. Axial fan is installed above the screen body to discharge heat;

(4) Select industrial-grade integrated circuit chips whose operating temperature is between -40°C and 80°C to prevent the display from failing to start when the temperature is too low in winter. ;

(5) In order to ensure long-distance visibility under strong ambient light conditions, ultra-high brightness light emitting diodes must be used; increase the contrast.

(6) The display medium adopts a new wide viewing angle tube, wide viewing angle, pure color, consistent coordination, and a life of more than 100,000 hours. The outer package of the display medium is the most popular covered square tube with silicone sealing and no metal assembly. Its appearance is exquisite and beautiful, durable, with direct sunlight protection, dustproof, waterproof, high temperature, and short circuits Five defense features.
