The main problem of outdoor screen is as follows:. A display installed outdoors, often sun and rain, wind and dust cover, poor working conditions. Electronic equipment is wet or damp can cause serious short circuit or fire, causing malfunction or a fire, resulting in losses. b. The display may be subject to strong electric magnetic attacks caused by lightning. c. the ambient temperature varies greatly. Work screen itself must have some heat, if the ambient temperature is too high heat and bad, IC may not work properly, or even destroyed, so the display system does not work. . d wide audience, sight distance requirements far and wide field of vision requirements; ambient light changes, in particular, may be subject to direct sunlight. For more specific requirements, outdoor display must be done: a Screen and the Screen and the building must be strictly water leak; Screen have good drainage measures in the event of a smooth water emissions. b. Install lightning protection devices on the display and buildings. Display body and cover good grounding resistance of less than 3 ohms, a large current caused by lightning discharge in time. c. Install ventilation cooling, so that the screen body internal temperature between -10 ℃ ~ 50 ℃. Behind the screen above the installed fan, exhaust heat. d. the choice of operating temperature between -40 ℃ ~ 80 ℃ industrial grade IC chip to prevent winter temperature is too low to make the display can not be started. e. Display media use the new wide viewing angle tube, wide viewing angle, color pure, consistent coordination, life over 100,000 hours. Display the outer packaging medium is the most popular with the cover along the square tube, silicone seal, metal-free assembly; its exquisite appearance, durable, with anti-direct sunlight, dust, water, high temperature, short circuit proof "Five Anti" feature.
