Now 4K and 8K technologies are gradually being widely used. What aspects should we pay attention to when purchasing small pitch LED screens?
1、 Follow the standard of "low brightness and high gray"
As a display terminal, COB small pitch LED screen should give priority to ensuring viewing comfort. To achieve this, the brightness scale of COB small pitch LED screen can only be between 100 cd/㎡ and 500 cd/㎡. However, in the traditional LED display techniques, reducing the screen brightness will result in the loss of gray, and the loss of gray will directly affect the image quality. Therefore, an important standard of high-quality COB small pitch LED screen is to "low brightness and high gray".
In real shopping, users can follow the principle of "the more brightness grades the human eye can recognize, the better". Luminance grade refers to the brightness grade of the image that can be distinguished by the human eye from the darkest to the whitest. The more grades, the larger the color gamut space of the display screen, and the richer the color representation.
2、 Select the resolution and pay attention to the matching with the "front-end transmission device"
The smaller the dot pitch of COB small pitch LED screen is, the higher the resolution is, and the higher the picture definition is. In real operation, users want to build the best COB small pitch LED display system. While storing the resolution of the screen itself, they should also consider the matching with front-end transmission products.
3、 Select the distance between points and pay attention to balancing "consequences and skills"
Compared with the traditional LED screen, the outstanding feature of COB small pitch LED screen is the smaller point spacing. In real use, the smaller the point spacing is, the higher the pixel density is, and the more information capacity can be expressed by the unit area at one time, the closer the optimal viewing distance is, on the contrary, the farther the optimal viewing distance is. Many users feel that the smaller the dot spacing of the optional display screen, the better. However, this is not the case.
With the penetration of 5G commercial, the COB small pitch LED display of PANAVISUAL also appears in all walks of life. The product has the advantages of strong reliability, fast heat dissipation, more mute, and obvious energy saving. The display effect can ensure that the audience can watch closely and for a long time without grainy feeling, and the visual enjoyment is more comfortable.
