Display more and more popular in recent years, the LED display screen and liquid crystal display plasma display for the display market, full-color LED display as a branch of the LED display, LED display in the prominent effect also won the welcome of the market. Outdoor full-color LED display installation requirements analysis: 1, in full color LED display screen and buildings are installed on the lightning protection device. Display the main body and the shell good grounding, grounding resistance is less than 3 ohm, lightning causes a large current discharge in a timely manner; Screen may be heavy current strong magnetic attacks caused by lightning. 2, the screen body, screen and the integration of a building must be strictly waterproof leak proof. Screen should have good drainage measures, in the event of water discharge smoothly; Pay attention to waterproof, moistureproof. Full color LED display is installed outdoors, and often, the wind dust cover, poor working conditions. Electronic equipment is wet or seriously be affected with damp be affected with damp will cause a short circuit or even fire, fault and even fire, loss. 3, install ventilation cooling equipment, makes the screen body internal temperature in - Range of 10 ℃ to 40 ℃. Behind the screen installed above the axial flow fan exhaust heat; Full-color LED display itself will generate a certain amount of heat at work, if the environment temperature and heat dissipation, integrated circuit may not work properly, and even destroyed, so that the display system cannot work normally. 4, in order to ensure that under the condition of the ambient light strong visual over a long distance, must choose high brightness leds; Increase the contrast, reach a wide, line-of-sight requirement, vision requires far and wide; Change of ambient light, and in particular may be direct sunlight; 5, choose new wide-field tube display medium, a broad perspective, color pure, consistent coordinate, life over 100000 hours display medium outside packaging is the most popular belt along the square cylinder, silicone seal, no metal cosmetic. 6, choose working temperature in - Between 40 ℃ ~ 80 ℃ industrial-grade integrated circuit chips, prevent winter temperature is too low to enable full-color LED display to start.
