The environment in which the LED display is located, whether it is outdoor, semi-outdoor, or indoors, is different, and the corresponding waterproof requirements are different. Outdoor waterproofing requirements are high, generally above IP65. According to the environment you are in, you can determine whether the approximate purchase range is an outdoor full-color display screen, a semi-outdoor full-color display screen, or an indoor full-color display screen!
The distance between the observation position and the installed display screen is the visual distance. This distance is very important. It directly determines the model of the display screen you choose. Generally, indoor full-color display models are divided into p1.9 and P2. P2.5, P3, p4, etc., outdoor full-color display models are divided into P4, P5, P6, P8, p10, etc., these are conventional, and there are also different specifications and models such as pixel screen, strip screen, special-shaped screen, etc. Again, we only talk about the conventional ones here. The number after P is the distance between lamp beads in millimeters. Generally, the minimum value of our visual distance is equivalent to the size of the number after P. That is, the distance between P10 > 10 meters. This method is only a rough estimate!
There is also a more scientific and specific method, which is to use the density of lamp beads per square to calculate. For example, if the point density of P10 is 10,000 points/square, then the distance is equal to 1,400 divided by (the square root of the point density). For example, the P10 is 1400/10000 square root = 1400/100 = 14 meters, that is, the distance to observe the P10 display is 14 meters away!
The above two methods directly determine the specifications of the selected LED full-color display. That is, customers must pay attention to two points when purchasing:
- The environment where the display screen is located.
- The distance between the observation position and the display screen. Only by understanding these can you choose an LED full-color display that matches your environment and achieves satisfactory results
