General customers in the purchase of LED full-color screen, the first thing to consider is the LED screen specifications.Let‘s see, LED full-color screen specifications are determined by those factors:

1. The environment of the display screen.Outdoor, semi-outdoor, or indoor, the environment is not the same, the corresponding waterproof requirements and brightness is not the same.Outdoor waterproof requirements are high, generally in IP65 and above.According to the environment can determine its general range of purchase and purchase is outdoor full-color screen or semi-outdoor full-color screen, or indoor full-color screen!

2. The distance between the optimal observation position and the installed display screen can be seen.This distance is very important, it directly determines what you display models of choose and buy, general indoor full-color displays models into the P6, P7.62, P10, P12, outdoor full-color displays models are divided into P10, P12, P16, P20 and so on, these are normal, also such as pixel screen, bar screen, screen for different types and different, such as only said routine, P at the back of the figure is the distance between lamp bead, the unit is mm, generally we the minimum visual distance is equivalent to the size of the P at the back of the digital.That is, the optimal spacing of 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 beads per square. For example, if the point density of P10 is 10000 points/square, the optimal distance is equal to 1400 divided by (the square root of point density).If P10 is 1400/10000 square root = 1400/100=14 meters, that is, the best observation distance of P10 display screen is 14 meters away!

3. Customer positioning.Now the production and production of LED display screen has entered the industrialization stage, and the product quality and price provided by each manufacturer are also uneven. In addition to understanding the customer‘s use environment and requirements, we should also understand the customer‘s positioning, so that we can choose products of different levels according to the customer positioning.Of course, we suggest customers to choose high-quality and inexpensive products, but we must remind customers that LED products have quality differences.These differences are divided into the following aspects:

A. Difference in the quality brand of LED components and driver chips used in the production of LED panel.

B. Technological differences in the production of LED panel.

C. Different materials and accessories are used to make LED full-color screens.For example: the power supply may use the brand, the aluminum profile and the wire rod choose the national standard.Then we can also use non-brand or non-target materials, so that the screen made in this way must be different in appearance and stability.

D. production technology.Capable and experienced companies have more mature and perfect processes, and products made from the same materials will be more stable.
