The LED display screen is located in an outdoor, semi outdoor or indoor environment. The corresponding waterproof requirements are different depending on the environment. Outdoor waterproof requirements are high, generally above IP65. According to the environment, it can be determined whether the general purchase range is outdoor full color display, semi outdoor full color display, or indoor full color display!
The distance between the observation position and the installed display screen, namely the visual distance, is very important. It directly determines the model of the display screen you choose to purchase. Generally, indoor full-color display screen models are divided into P1.9, P2, P2.5, P3, p4, etc., while outdoor full-color display screen models are divided into P4, P5, P6, P8, p10, etc. These are conventional, such as pixel screen, strip screen, special-shaped screen, and other specifications and models are different. Here, we will just talk about conventional ones, The number after P is the distance between lamp beads, in mm. Generally, the minimum value of our visual distance is equivalent to the size of the number after P. That is, P10 spacing: 10m, this method is only a rough estimate.
In addition, there is a more scientific and specific method, which is to calculate the lamp bead density per square. For example, if the point density of P10 is 10000 points/sqm, the distance is equal to 1400 divided by (the square root of the point density). For example, the square root of P10 is 1400/10000=1400/100=14m, that is, the distance to observe P10 display screen is 14m away.
The above two methods directly determine the specifications of the selected LED full-color display screen, that is, customers must pay attention to two points when purchasing:
1. The environment in which the display is located.
2. The distance between the observation position and the display position. Only by understanding these, can you choose a full-color LED display that matches your environment and achieves satisfactory results.
