the environment of led display screen is outdoor led screen, semi-outdoor led wall, or indoor led panels. the environment is different, and the corresponding waterproof requirements are different. outdoor waterproofing requirements are high, generally over ip65. according to the environment, we can determine whether the scope of purchase is outdoor full-color display or semi-outdoor full-color display, or indoor full-color display!
the distance between the observation position and the installed display screen is visual distance, which is very important. it directly determines the type of display screen you choose. generally, the indoor full-color display screen is divided into p1.9, p2, p2.5, p3, p4 and so on. the outdoor full-color display screen is divided into p4, p5, p6, p8, p10 and so on. these are conventional, but also better than others. for example, pixel screen, strip screen, special-shaped screen and other specifications and models are different, here we only say that conventional, the number behind p is the distance between the beads, unit is millimeter, generally our minimum visual distance is equivalent to the size of the number behind p. that is, the distance of p10 is 10 meters. this method is only a rough estimate.
there is also a more scientific and specific method, that is, to calculate the density of beads per square. for example, if the point density of p10 is 10000 points per square, the distance is equal to 1400 divided by the square of the point density. for example, p10 is 1400/10000 square meters = 1400/100 = 14m, that is, the distance of observing p10 display screen is 14 meters away!
the above two methods directly determine the specifications of the selected full-color led display, that is, customers must pay attention to two points when choosing and purchasing:
1. the environment of the display screen.
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.
