Outdoor LED display focus more on maintenance, which experienced wind and rain. So we need to choose the better material, and now more and more LED display manufacturers resulting in the bad quality of LED display which is not a good protection system.
Many customers are not clear to the matters after purchased outdoor LED display and not pay attention to the quality guarantee.
Indoor and outdoor LED display are two kinds of working environment, which the requirements for outdoor LED display needs to pay more attention to the outdoor environment.
Please be noted for the following points:
1. The display is installed for outdoor, often in sun and rain, wind and dust cover, poor working environment. Electronic equipment will be damp or severe damp will cause a short circuit or even fire, causing failure or even fire, causing losses.
2. The display may be caused by lightning strong magnetic field attack.
Ambient temperature changes greatly. The display works itself to produce a certain amount of heat, if the ambient temperature is too high and poor heat, the integrated circuit may work abnormal, or even burned, so that the display system can not work properly.
3. Wide audience, vision requirements, wide field of vision requirements, large changes in ambient light, in particular, may be exposed to direct sunlight.
For the above special requirements, outdoor display must be done these issues:
First, screen body and the building must be strict combination for waterproof and leak proof.
Screen body should be in a good drainage measures, once the occurrence of water can be discharged smoothly. Install lightning protection devices on displays and buildings. The display theme and the shell to maintain a good grounding. And grounding resistance is less than 3 ohms, lightning caused by the timely discharge of large current.
Second, install the ventilation equipment cooling, so that the screen inside the temperature between -10 ℃ -40 ℃. Also installed axial fan behind the top of the screen, excluding heat.
Use the operating 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.
Lastly, in order to ensure that the environment in the case of strong long-range visual, you must use ultra-high brightness light-emitting diodes.
Display media selection chooses new wide viewing angle, pure color, consistent coordination and more than 100,000 hours lifespan. The outer packaging of the display medium is the most popular with the side cover along the square tube, silicone seal, no metal assembly. Its exquisite appearance beautiful, durable, with anti-sun direct, dust, water, high temperature, five anti “features”.
