There are many types of LED electronic large screens, and the appropriate LED electronic large screen products can be selected according to the use environment and functional requirements. Many users have vague concepts when choosing LED large screens. First, determine the size and ratio of LED electronic large screens that are suitable for the installation environment, and then locate the appropriate functional requirements. There are many details that need to be paid attention to during the installation process of LED electronic large screens. The display medium adopts a new type of wide viewing angle tube, which has a wide viewing angle, pure colors, and consistent coordination. The LED electronic large screen has a life span of more than 100,000 hours. The outer packaging of the display medium is the most popular square cylinder with a cover edge, silicone seal, and no metallized assembly. ; The appearance of the LED electronic screen is exquisite and beautiful, sturdy and durable, and has the characteristics of preventing direct sunlight, dustproof, waterproof, high temperature and short circuit. The screen body and the joint between the screen body and the building must be strictly waterproof and leak-proof; the screen body of the LED electronic large screen must have good drainage measures, and once water accumulation occurs, it can be discharged smoothly; pay attention to waterproof and moisture-proof. The LED electronic large screen is installed outdoors, often exposed to the sun, rain, wind and dust, and the working environment is harsh. Wet or severely damp electronic equipment will cause short circuit or even fire, causing failure or even fire, resulting in losses; select industrial-grade integrated circuit chips with operating temperatures between -40°C and 80°C to prevent the LED electronics from being too low in winter Screen won't start. Install ventilation equipment to cool down, so that the internal temperature of the LED electronic large screen body is between -10°C and 40°C. An axial flow fan is installed on the back of the screen to discharge heat; when the LED electronic large screen is working, it will generate a certain amount of heat. The large-screen display system cannot work normally; install lightning protection devices on LED electronic large screens and buildings. The main body and shell of the LED electronic large screen should be well grounded, and the grounding resistance should be less than 3 ohms, so that the large current caused by lightning can be discharged in time; the LED electronic large screen may be attacked by strong electricity and magnetism caused by lightning. In order to ensure that the LED electronic screen is visible at a long distance under the condition of strong ambient light, ultra-high brightness light-emitting diodes must be selected; increase the contrast, wide audience, long viewing distance, and wide field of view; large ambient light changes, large LED electronic screens Especially may be exposed to direct sunlight. .
