How to choose good outdoor LED display?
Today,more and more industry need use LED display,then we need how to choose a right outdoor LED display?
There are many kinds of LED display screens, which can be divided into indoor screen and outdoor screen according to the use environment.
Indoor LED screens are very different from outdoor LED screens.
It is brightness is different above all, the luminance brightness of indoor screen should go out a few times lower than outdoor screen to dozens of times;
Putting an indoor screen outside is like putting a TV outside.
Therefore, the outdoor screen must use ultra-high brightness LED, and in order to further improve the brightness and increase the visual distance, in a pixel often need to encapsulate a number of ultra-high brightness LED, secondly, the outdoor screen must prevent (rain) water, prevent direct sunlight, dust, high temperature, wind, lightning, etc., and the indoor screen is not required to consider these issues.
At present, the main problems of the outdoor screen are as follows :
1. The screen is installed in the outdoor, often in the sun and rain, the wind blows dust cover, the working environment is bad.
If the electronic equipment is wet or seriously wet, it will cause short circuit or even fire, cause malfunction or even fire and cause loss.
2. The screen may be hit by strong electricity and magnetism caused by lightning.
3. Environmental temperature varies greatly.The screen itself will generate a certain amount of heat when working. If the ambient temperature is too high and the heat dissipation is not good, the integrated circuit may not work normally, or even be burned down, so that the display system cannot work normally.
4. Wide audience, long visual distance and wide field of vision.
Ambient light varies greatly, especially when exposed to direct sunlight.
Solution and application requirements :
1. The screen body and the joint of the screen body and the building must be strictly waterproof and leakproof.
The screen should have good drainage measures, once the occurrence of water can be discharged smoothly.
2. Install lightning arrester on the screen and building.
The screen body and the housing are well grounded, and the grounding resistance is less than 3 ohms, so that the large current caused by lightning can be released in time.
3. Install ventilation equipment to cool down, so that the internal temperature of the screen body is between -10℃ and 40℃.
An axial flow fan is installed above the back of the screen to discharge heat.
4. Industrial grade integrated circuit chip with operating temperature between -40℃ and 80℃ is selected to prevent the screen from starting due to too low temperature in winter.
5. In order to ensure remote vision in the case of strong ambient light, ultra high brightness led must be selected
