Sounds let customer some worry, but as long as the manufacturer of outdoor LED display to solve things mentioned below, is can rest assured the choose and buy.
Main problem of outdoor screen, as follows: display installed outdoors, regular exposure rain, 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.
Second, the display may be heavy current strong magnetic attacks caused by lightning.
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 do: (
Install ventilation cooling equipment, makes the screen body internal temperature in -
Between 45 ℃.
Behind the screen above installed axial flow fan, exhaust heat.
Choose working temperature in -
Between 80 ℃ industrial-grade integrated circuit chips, to prevent the winter temperature is too low to make display can not start.
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.
Screen and screen and building the junction must be strictly waterproof leakage protection;
Screen should have good drainage measures, in the event of water discharge smoothly.
In order to guarantee the environment under the condition of strong visual over a long distance, must use high brightness leds.
Display medium choose new wide-field tube, 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.
Through the above processing, outdoor LED display in addition to its appearance is delicate and beautiful, durable, also has the direct sunlight, dustproof, waterproof, prevent heat, prevent short circuit 'five prevention' characteristics.
