Discussion on design and installation of outdoor LED display screen

For outdoor LED display in the normal operating state for a long time, the design and installation, engineers will consider many possible problems, such as the following:

The main problems are as follows: user screen

(1) display installed in the outdoor, often the sun and rain, the wind blew the dust cover, poor working environment. Electronic equipment is wet or serious damp will cause short circuit or even fire, cause trouble or even fire, cause damage;

(2) display may be affected by the strong electric magnetic attack caused by lightning;

(3) environmental temperature changes greatly. When the screen is working, it will produce a certain amount of heat, if the ambient temperature is too high and the heat is bad, the integrated circuit may not work properly, or even burned, so that the display system can not work properly;

(4) wide audience, visual vision requires far and wide; changes in ambient light, especially sunlight may.

According to the special requirements of the outdoor display must be:

(1) combination of screen and screen and the building must be strictly waterproof leak; the screen body should have good drainage facilities, water can be discharged smoothly once;

(2) install lightning protection devices in buildings and display. The main body and the shell of the display screen are well grounded, and the grounding resistance is less than 3 ohms, so that the high current caused by lightning can be discharged in time;

(3) installed ventilation cooling equipment, the internal temperature of the screen body between -10 to 40 DEG C. The axial fan is installed on the back of the screen body to discharge heat;

(4) adopts industrial grade integrated circuit chip working temperature between -40 to 80 DEG C, prevent winter temperature is too low so that the screen can not start. ;

(5) in order to ensure the environmental light under the strong visual distance, must use the ultra high brightness light-emitting diode; increasing the contrast.

(6) display media selection from the perspective of new type wide tube, wide viewing angle, pure color, harmony, life more than 100 thousand hours. Display package media is currently the most popular cover band along the square cylinder, silica gel seal, with no metal assembly; the appearance of fine appearance, durable, anti sunlight, dustproof, waterproof, anti high temperature, anti short circuit protection features five.
