1.Install lightning protection devices on display and buildings. The display body and the shell to maintain a good grounding, grounding resistance is less than 3 ohms, lightning caused by the timely discharge of large current; display may be caused by lightning strong magnetic attack
2. Screen body and the screen body and the combination of the building must be strictly waterproof and leakproof; screen body should have a good drainage measures, once the occurrence of water can be discharged; pay attention to waterproof, moisture. The display is installed outdoors, often sun and rain, wind and dust cover, working environment is bad. Electronic equipment is damp or severe damp will cause short-circuit or even fire, causing failure or even fire, resulting in loss;
3. Use the working temperature of -40 ℃ ~ 80 ℃ between the industrial-grade integrated circuit chip to prevent the winter temperature is too low so that the display can not start.
4. Install the ventilation equipment cooling, so that the screen inside the temperature between -10 ℃ ~ 40 ℃. The display screen work itself will have to produce a certain amount of heat, if the ambient temperature is too high and poor heat, the integrated circuit may work is not normal, or even burned, so that the display system can not be normal jobs;
5. In order to ensure that the ambient light in the case of long-distance visual, you must use ultra-high brightness light-emitting diodes; increase the contrast. Wide audience, wide viewing distance, wide field of vision requirements; ambient light changes, especially may be sunshine Direct.
6. Display medium selection of a wide range of wide viewing angle tube, wide viewing angle, pure color, consistent coordination, life of more than 100,000 hours display media outer package for the current most popular with a square tube, silicone seal, no metal assembly; Sophisticated appearance, durable, with anti-sun direct, dust, water, high temperature, anti-circuit short circuit five anti-characteristics
