Sep. 12, 2019

Following shared by LED HD screen Touch Monitor supplier.

The main problems of outdoor screens are as follows:

(1) the display screen is installed outdoors, often exposed to the sun, rain, wind and dust cover, and the working environment is harsh. Electronic equipment is wet or seriously affected by moisture will cause short circuit or even fire, cause fault or even fire, resulting in losses;

(2) the display screen may be attacked by strong electric and magnetic force caused by lightning;

(3) the environment temperature changes greatly. The display screen itself will generate a certain amount of heat when working. If the ambient temperature is too high and the heat dissipation is not good, the integrated circuit may not work properly or even be burned, so that the display system cannot work normally.

(4) wide audience, long visual distance and wide field of vision; Ambient light varies greatly, especially when exposed to direct sunlight.

For the above special requirements, outdoor display screens must:

(1) the OLED dual monitor body and the combination of the screen body and the building must be strictly waterproof and leakproof; Screen should have good drainage measures, once the occurrence of water can be discharged smoothly;

(2) install lightning protection devices on display screens and buildings. The main body and shell of the display screen are well grounded, and the grounding resistance is less than 3 ohms, which makes the large current caused by lightning timely discharge.

(3) install ventilation equipment to cool the temperature, so that the internal temperature of the screen is between -10℃ and 40℃. Axial flow fan is installed above and behind the screen to discharge heat;

(4) industrial grade IC chips with operating temperature between -40℃ and 80℃ are selected to prevent the display screen from starting in winter when the temperature is too low. ;

(5) in order to ensure the remote vision under the circumstance of strong ambient light, ultra-high brightness light-emitting diode must be selected;

(6) 4k Touch Monitor supplier says that display medium selection of new wide perspective tube, wide perspective, pure color, consistent coordination, life more than 100,000 hours. The external package of the display medium is the most popular square cylinder with cover, sealed with silica gel, no metal makeup; Its appearance is delicate and beautiful, strong and durable, with direct sunlight, dust, waterproof, high temperature, short circuit prevention "five" characteristics.
