How to choose a small-pitch LED display?

1. "Low brightness and high gray" is the premise:

Indoor small-pitch LED display screens are used as display terminals. First of all, it is necessary to ensure the comfort of viewing. Therefore, when purchasing, the primary concern is the brightness problem. Relevant studies have shown that, in terms of human eye sensitivity, LED as an active light-emitting source, its brightness is twice that of a passive light-emitting source, and to ensure the comfort of human eyes, the brightness range of a small-pitch full-color LED display can only be Between 100cd/m2-300 cd/m2.

2. When choosing the point spacing, pay attention to the balance of "effect and technology"

Compared with the traditional LED screen, the outstanding feature of the indoor small-pitch LED display is the smaller dot pitch. In practical applications, the smaller the dot pitch, the higher the pixel density, the more information capacity per unit area can be displayed at one time, and the closer the distance suitable for viewing. On the contrary, the longer the distance suitable for viewing. Many users naturally think that the smaller the dot pitch of the product, the better. However, this is not the case.

Conventional LED screens want to achieve the best visual effects and have the best viewing distance. The same is true for indoor small-pitch LED displays. Users can make simple calculations through the best viewing distance=dot spacing/0.3~0.8. For example, the best viewing distance of the P2 small-pitch LED screen is about 6 meters away. We know that the smaller the dot pitch, the higher the cost of a small-pitch full-color LED display. Therefore, in actual purchase, users must comprehensively consider their own cost, demand, application range and other factors.

3. When choosing the resolution, pay attention to the match with the "front-end signal transmission equipment"

The smaller the dot pitch of the indoor small-pitch LED display, the higher the resolution, and the higher the picture clarity. In actual operation, users want to build the best small-pitch LED display system. While paying attention to the resolution of the screen itself, they must also consider the combination of it and the front-end signal transmission product.
