The environment in which LED display screens are located, whether outdoor, semi-outdoor or indoor, varies, and so do the corresponding waterproofing requirements. The outdoor waterproofing requirements are high, generally above IP65. Based on the environment you are in, you can roughly determine whether your purchase range is outdoor full-color display screens, semi-outdoor full-color display screens, or indoor full-color display screens!
The first method
The distance between the observation position and the installed display screen, that is, the viewing distance, is very important as it directly determines the model of the display screen you purchase. Generally, the models of indoor full-color display screens include p1.9,P2,P2.5,P3,p4, etc., and the models of outdoor full-color display screens include P4, P5, P6, P8, p10, etc. These are all common ones. The number following "P" represents the distance between the light beads, with the unit being millimeters. Generally, the minimum value of our visible distance is equivalent to the size of the number following "P". That is, the distance between P10 is less than 10 meters. This method is only a rough estimate!
The second method
There is another more scientific and specific method, which is to calculate using the density of the lamp beads per square meter. For example, if the point density of P10 is 10,000 points per square meter, then the distance is equal to 1400 divided by (the square root of the point density). For instance, for the P10, it is 1400/10,000 square kilometers = 1400/100=14 meters. That is to say, the distance from which you can observe the P10 display screen is 14 meters away!
Summary
The above two methods directly determine the selected LED full-color displays of the specifications of the problem, is that the customer is when the choose and buy must pay attention to two points: 1. the display environment. 2.observation location away from the distance from the center of the screen. Only by understanding these can you select an LED full-color display screen that matches your environment and achieves a satisfactory effect.
