What is the concept of LED display screen flatness?
When we install an LED display screen, we touch the surface with our hands. If there is a noticeable unevenness, it indicates poor flatness. In the LED display screen industry, "flatness" is used to describe the degree of unevenness on the surface of the display screen, measured in millimeters (mm).

2. What factors affect the size of flatness?
The size of flatness is mainly determined by the material and production process, and is divided into flatness between modules and flatness between boxes. The factors that affect the flatness between modules are the PCB light board accuracy, bottom shell accuracy, and frame accuracy; The factors that affect the flatness between the boxes are the accuracy of the frame and the accuracy of the side lock.
What are the benefits of low flatness
The flatness of LED display screens is generally between 0.1-0.3mm, and the flatness of small pitch display screens is required to be below 0.1mm. The smaller the flatness, the smoother the display screen, the more uniform the colors, and the better the viewing effect; The greater the flatness, the more prone the display screen is to distortion, the more prone the colors are to discontinuity, and the viewing effect is worse.
Therefore, when purchasing LED display screens. In addition to focusing on point spacing, resolution, brightness, and price, attention should also be paid to installation smoothness. Quality is evident in every detail.
