The first thing that users pay attention to when buying small -pitch LED products are the problem of brightness. In the traditional LED display technology, reducing the screen brightness will cause gray loss, and the losses of grayscale will directly affect the quality of the picture, that is, the color is not rich enough. Therefore, an important criterion for a high -quality small spacing LED screen is to reach the "low bright and high gray" technical indicator.

Pay attention to the balance of the balance and technology compared to the traditional LED display, the prominent feature of the small spacing LED is the smaller point spacing. In practical applications, the smaller the point spacing, the higher the pixel density, the closer the distance suitable for viewing. On the contrary, the farther the distance suitable for watching. If the small spacing LED display wants to achieve the best visual effect, there is the best visual distance. The user can make simple calculations. There is a established formula, that is, the best visual distance = point spacing /0.3 ~8. The smaller the point spacing, the higher the cost of the small spacing LED display. Therefore, in actual purchase, users should comprehensively consider their own cost, demand, and application scope.

　　Third Key points: Resolution: Pay attention to combining with the back -end signal transmission For small spacing LED display, the smaller the point spacing, the higher the resolution, the higher the definition of the picture, but in the actual operation, the industry users, the user of the industry, the users of the industry, the industry users To build the best small -spacing LED display system, while paying attention to the screen body's own resolution, it is also necessary to consider the matching with the back -end signal transmission product.
