following aspects can be considered when purchasing a small-pitch LED display:

1. "Low light and high gray" is the premise
An important criterion for high-quality small-pitch LED screens is to achieve the technical indicators of "low brightness and high gray". In actual purchase, users can follow the principle of "the more brightness levels the human eye can recognize, the better".

2. Select the point spacing, pay attention to the balance of "effect and technology"
The point spacing of the purchased products is not as small as possible. Users can make simple calculations through the optimal visual distance = point spacing / 0.4~0.8, and comprehensively consider their own costs, needs, application scope and other factors.

3. Select the resolution, pay attention to the matching with the "front-end signal transmission equipment"

Users who want to build the best small-pitch LED display system should not only pay attention to the resolution of the screen itself, but also consider the combination with the front-end signal transmission products, and select the matching video support format.
