Outdoor LED display which problems - should be considered
Full color LED screen - knowledge
One, the screen installed outdoors, and often, 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;
Second, the display may be limited by lightning caused heavy current strong magnetic attack;
Three, the environment temperature changes greatly.
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;
Four, at a wide, line-of-sight requirement, vision requires far and wide;
Change of ambient light, and in particular may be direct sunlight.
Special requirements for the above, the outdoor screen must be: a, screen and screen and the integration of a building must be strictly waterproof leakage protection;
Screen should have good drainage measures, in the event of water discharge smoothly;
Second, in the lightning protection devices are installed on the screen and buildings.
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;
Three, install ventilation cooling equipment, makes the screen body internal temperature in -
Range of 10 ℃ to 40 ℃.
Behind the screen above installed axial flow fan, exhaust heat;
Fourth, choose working temperature in -
Between 40 ℃ ~ 80 ℃ industrial-grade integrated circuit chips, prevent winter low temperature display cannot start.
Five, in order to ensure that under the condition of the ambient light strong visual over a long distance, must choose high brightness leds;
Six, choose new wide-field tube display medium, a broad perspective, color pure, consistent coordinate, life over 100000 hours.
Display medium outer packaging for the most popular belt along the square cylinder, silicone seal, no metal cosmetic;
Its appearance delicate and beautiful, durable, resistant to direct sunlight, dustproof, waterproof, anti high temperature, prevent short circuit 'five prevention' characteristics.
