The p0.9 led screen manufacturer tells you that there are many led small pitch displays on the street. Some look really good, with beautiful color, even brightness, and good flatness. However, some LED fine pitch displays seem to have a layer of stuff on the surface, with occasional flickering, and the screen surface is not flat. P0.9 led screen manufacturers analyze the skills to test the performance of led small-pitch displays.

1. The control card is basically outsourced by the LED display manufacturer. The p0.9 led screen manufacturer tells you that some brands of control cards are in relatively good working condition. These control cards are used on the LED small-pitch display. Relatively speaking, Better stability.
2. LED small-pitch display driver IC: p0.9 led screen manufacturers tell you that the image quality of the IC with better performance is very good, clear, no scanning lines, and low failure rate.
3. Circuit board: There are relatively many domestic circuit board manufacturers. The circuit board can be divided into two layers and four layers, and the thickness of the two layers is 1.6. Four-layer board is 2.0. The element that can affect the quality of the board is the internal conductors of the board. The thickness of the conductor must reach the standard thickness of more than 1ns, because the LED small-pitch display will have a trend of temperature rise and fall during operation; the p0.9 led screen manufacturer tells you that if the conductive copper is very thin, the LED module is in use. Melting during the process can cause a wide range of quality problems.
4. The problem of the mask and the kit: The p0.9 led screen manufacturer tells you that the consistency of the ink color of the mask will directly affect the flickering effect of the LED full-color screen. Assuming that the ink color is good and the quality of the LED light is good, basically flickering is not a big problem.
5. The waterproof performance of outdoor led small-pitch display depends on whether it is mechanical glue or manual glue. The quality of glue is related to the proportion of AB glue.
6. The craftsmanship of the box: The p0.9 led screen manufacturer tells you whether the box is flat or not is related to the machine equipment and manual welding technology of the led display manufacturer. After the LED small-pitch display frame is completed, the flatness of the entire screen will be better, and the seams will be small.
7. Brightness: p0.9 led screen manufacturers tell you that it is not that the higher the brightness, the better, because increasing the current can increase the brightness of the LED light, but it will affect the life of the LED display. Some outdoor LED fine pitch display screens have high brightness, which makes you look good, but usually not for a year. Therefore, the brightness is sufficient. Uniformity means that the brightness is almost subdued and can be viewed in lighting conditions. If the brightness is not uniform, it will look dirty, just like it is not clean.
