Is the Flatness of LED Display Screen Important?

What is the concept of flatness in LED display screens?

When we install an LED display screen, we use our hands to touch the surface of the screen. If there is an obvious uneven feeling, it indicates 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 screen, and the unit is millimeters (mm).

What factors affect the size of flatness?

The size of flatness is mainly determined by materials and production processes, and is divided into the flatness between modules and the flatness between cabinets. The factors that affect the flatness between modules are the accuracy of the PCB board, the bottom shell, and the frame. The factors that affect the flatness between cabinets are the accuracy of the frame and the lock on the side.

What are the benefits of having a small flatness?

Generally, the flatness of LED display screens is between 0.1-0.3mm, and the flatness requirement for small-pitch display screens is below 0.1mm. The smaller the flatness, the smoother the display screen, the more uniform the color, and the better the viewing effect. The larger the flatness, the easier the display screen is to distort, the more likely the color is to break, and the worse the viewing effect.

Therefore, when purchasing an LED display screen, in addition to paying attention to the dot pitch, resolution, brightness and price, attention should also be paid to the installation flatness. Quality is in the details.
