For special requirements, outdoor display must do
( 1 ) selecting an industrial-grade integrated circuit chip with a working temperature between - 40 deg c and 80 deg c to prevent the four-way chip of the led display screen from starting due to low winter temperature;
( 2 ) in order to ensure long-distance visibility under the condition of strong ambient light, ultra-high brightness light emitting four-way diode must be selected;
( 3 ) the display medium adopts a novel wide viewing angle tube, the viewing angle is wide, the color of the four-way chip is pure, consistent and coordinated, and the service life is more than 100,000 hours. The outer 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 delicate and beautiful, strong and durable, with direct sunlight, dust - proof, waterproof, high temperature, circuit short-circuit resistance " five prevention" features;
( 4 ) the screen and the combination of the screen and the building must be strictly waterproof and leakproof; Screen should have good drainage measures, once the water can be discharged smoothly;
( 5 ) install lightning protection device on the display screen and buildings. The main body and the shell of the led electronic display screen are kept well grounded, and the grounding resistance is less than 3 ohms, so that large current caused by thunder and lightning is discharged in time;
( 6 ) installing ventilation equipment for cooling, so that the internal temperature of the screen body is between - 10 deg c and 40 deg C.. An axial flow fan is arranged at the upper part of the back of the screen body to discharge heat and prolong the service life of the four-way led display.
