How to choose LED pole screen?
one
The junction of LED light pole screen and building must be strictly waterproof and leak proof: the screen body should have good drainage measures, and once ponding occurs, it can be discharged smoothly.
two
The main body and shell of the display shall be well grounded, and the grounding resistance shall be less than 3 ohm, so that the large current caused by lightning can be discharged in time.
three
Install ventilation equipment can reduce the temperature, so that the internal temperature of LED light pole screen is between - 10'C ^ and 40 ℃. An axial flow fan is installed at the back and upper part of the screen to dissipate heat.
four
The industrial grade IC chip with working temperature between - 40'c and 80 ℃ is selected to prevent the LED light pole screen from starting when the temperature is too low in winter.
five
In order to ensure long-distance visibility under strong ambient light, ultra-high brightness LED must be selected for LED pole screen.
six
The display medium of LED light pole screen adopts a new type of wide viewing angle tube, with wide viewing angle, pure color, consistent coordination, and service life of more than 100000 hours. The external packaging of the display medium is the most popular square cylinder with shielding edge, sealed with silica gel, and no metallization assembly: its appearance is exquisite and beautiful, firm and durable, and has the functions of direct sunlight protection, dust prevention, water resistance, high temperature protection and short circuit prevention.
