What kind of LED advertising screen is suitable for outdoor media

As a kind of outdoor advertising media, outdoor LED display, has now been widely used in many advertisers favor. Purchase outdoor LED display requires not only high brightness wide view far sight distance, but also consider the wind rain lightning protection of high and low temperature resistance and other factors, because the outdoor LED display screen may face various outdoor harsh environment in use, such as wind, rain, lightning, high and low temperature, sandstorm.
1.The audience visibility
Audience and wide, sight distance requirements far, wide view requirements; ambient light changes, especially may be subject to direct sunlight. In order to ensure the environmental light under strong remote video, must use the ultra high brightness light-emitting diode。
The display medium selection from the perspective of new type wide tube, wide viewing angle, pure color, consistency, life more than 100000 hours. Display package media is currently the most popular band cover along the square cylinder body, a silica gel sealing, no metal assembly; the appearance is delicate and beautiful, strong and durable, with anti sunlight, dustproof, waterproof, anti high temperature, anti short circuit characteristics。
2.Waterproof lightning protection
The display screen is installed outdoor, often exposed to the sun and rain, the wind blew the dust cover, poor working environment. Electronic equipment is wet or damp will cause a short circuit fire even serious, caused the fault and even fire, causing the loss of. So the combination part display screen and the screen body and building the purchase must be strictly waterproof and leakage proof; the screen body to have good drainage facilities, once the occurrence of water can smoothly discharge.
Outdoor LED display screen may be affected by the strong electric magnetic attacks caused by lightning. So buy screen to install lightning protection apparatus in the display screen and the building. The display main body and the housing to maintain a good grounding, grounding resistance less than 3 ohm, high current lightning induced timely discharge
3.Heat resistance to low temperature
The temperature of the environment change greatly. Display work itself will produce some heat, if the ambient temperature is too high and the heat dissipation and the bad, the integrated circuit may not work properly, even burned, so that the display system can work normally; the installation of ventilation cooling equipment, the internal temperature of the screen body is between -10 to 40 DEG C. Behind the screen body is arranged above the axial flow fan, the heat discharge; selection of industrial grade integrated circuit chip operating temperature between -40 to 80 DEG C, prevent winter temperature is too low so that the display screen can not start
