Is LED display flatness important?

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 the flatness is not good. In the LED display industry, "flatness" is used to describe the degree of unevenness of the display surface, and the unit is millimeters (mm).

 2. What are the factors that affect the size of flatness?

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

 3. What are the benefits of small flatness? ：

Generally, the flatness of LED display is between 0.1-0.3mm, and the flatness of small pitch display is required to be below 0.1mm. The smaller the flatness, the smoother the display screen, the more uniform the color, and the better the viewing effect; The greater the flatness, the more likely the display screen is to be distorted, the more likely it is to have color faults, and the worse the viewing effect is.

Therefore, when you buy LED displays. In addition to focusing on point spacing, resolution, brightness, and price, you should also pay attention to the flatness of the installation. It's the subtleties that see the quality.
