The environment in which the LED display is located is outdoors, semi-outdoors, or indoors. The environment is different, and the corresponding waterproof requirements are different. Outdoor waterproof requirements are high, generally above IP65. According to the environment, you can determine whether the approximate purchase range is an outdoor full-color display or a semi-outdoor full-color display, or an indoor full-color display! 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, the indoor full-color display screen models are divided into p1.9, P2, P2.5, P3, p4, etc., outdoor full-color display models are divided into P4, P5, P6, P8, p10, etc., these are all conventional, such as pixel screen, strip screen, special-shaped screen and other specifications and models are not Same, here only talk about conventional, the number behind P is the distance between the lamp beads, the unit is mm, generally the minimum value of our visual distance is equivalent to the size of the number behind P.
That is, the distance between P10>10 meters, this method is only a rough estimate! In addition, there is 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, the distance is equal to 1400 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 screen 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: 1. The environment in which the display is located. 2. The distance between the observation position and the display screen position.
Only by understanding these, can you choose a full-color LED display that matches your environment and achieves satisfactory results. .
