1. What is the concept of LED display flatness?

When we install the LED display, we will touch the surface of the LED display with our hands, if there will be an obvious feeling of unevenness, then it means that the flatness is not good. In the LED display industry, "flatness" is used to describe the degree of unevenness on the surface of the display, measured in millimeters (mm).

2. What factors affect the flatness?

The size of the flatness is mainly determined by the material and production process, and is divided into the flatness between modules and the flatness between boxes. The factors affecting the flatness between modules are PCB light board accuracy, bottom shell accuracy and frame accuracy. The factors affecting the flatness between the boxes are frame accuracy and side lock accuracy.

3. What are the benefits of small flatness? ：

Generally, the flatness of LED displays is between 0.1-0.3mm, and the flatness of small-pitch displays is required to be less than 0.1mm. The smaller the flatness, the smoother the display picture, the more uniform the color, and the better the viewing effect; The greater the flatness, the more likely the display image is to be distorted, the more prone the color is to fault, and the worse the viewing effect.

Therefore, when you buy LED displays, In addition to focusing on spacing, resolution, brightness, and price, you should also pay attention to the flatness of the installation. Quality is seen in the subtleties.
