When we buy led small spacing display screen, users should consider their own cost, demand, application scope and other factors. Before buying a small spacing LED display, first determine whether a small spacing is really needed. This should be determined according to the actual situation. At the same time, the following points need to be paid attention to.


1、 "Low brightness and high gray" is the premise

As a display terminal, the small spacing LED screen should first ensure the viewing comfort. Therefore, when purchasing, the primary concern is the brightness. Relevant research shows that from the perspective of human eye sensitivity, as an active light source, the brightness of LED is twice that of passive light source (projector and LCD). In order to ensure the comfort of human eyes, the brightness range of small spacing LED screen can only be between 100 CD / m2 and 300 CD / m2.


2、 When selecting point spacing, pay attention to the balance between "effect and technology"


In order to achieve good visual effect, some conventional LED screens have viewing sight distance, and the same is true for small spacing LED screens. Users can simply calculate by visual distance = point spacing / 0.3 ~ 0.8. For example, the viewing distance of P2 small spacing LED screen is about 6m away.

3、 When selecting the resolution, pay attention to the matching with "front-end signal transmission equipment"

The smaller the dot spacing of the small spacing LED screen, the higher the resolution, and the higher the definition of the picture. In practice, if users want to build a good small spacing LED display system, they should not only pay attention to the resolution of the screen itself, but also consider its matching with the front-end signal transmission products.
