Compared with traditional LED screens, the prominent feature of small pitch LED screens is their smaller dot spacing.
1. Low brightness and high gray are prerequisites:
As a display terminal, the small spacing LED screen should first ensure the comfort of viewing. Therefore, when choosing, the primary concern is the brightness issue. Related studies have shown that in terms of human eye sensitivity, LED, as an active light source, has twice the brightness of passive light sources (projectors and LCD displays). To ensure comfortable viewing for the human eye, the brightness range of small pitch LED screens can only be between 100 cd/m2 and 300 cd/m2.
2. When selecting point spacing, pay attention to balancing “effects and techniques”
Compared with traditional LED screens, the prominent feature of small pitch LED screens is their smaller dot spacing. In practical applications, the smaller the point spacing, the higher the pixel density, and the more information per unit area that can be displayed at once, the closer the suitable viewing distance is. Conversely, the farther the suitable viewing distance is. Many users naturally believe that the smaller the spacing between points when choosing a product, the better. However, this is not the case.
Conventional LED screens require the best viewing range to achieve the best visual effect, as do small pitch LED screens. Users can make simple calculations by using the optimal viewing distance=point spacing/0.3~0.8. For example, the optimal viewing distance for P2 small pitch LED screens is about 6 meters away.
3. When choosing a resolution, pay attention to the combination with the “front-end signal transmission equipment”
The smaller the dot spacing of the small pitch LED screen, the higher the resolution, and thus the higher the clarity of the image. In practical operation, if users want to build the best small pitch LED display system, they should not only pay attention to the resolution of the screen itself, but also consider its combination with front-end signal transmission products.
For example, in security monitoring applications, front-end monitoring systems typically include video signals in formats such as D1, H.264, 720P, 1080I, and 1080P. However, not all small pitch LED screens on the market can support video signals in these formats. Therefore, to avoid resource waste, users must choose small pitch LED screens according to their needs and avoid blindly following the trend.
At present, small pitch LED products have been widely used in television studios, power system monitoring centers, aerospace command centers, military command centers, government halls, urban monitoring centers, video conference rooms, dispatch rooms, airports, train stations, hotels, and large and medium-sized enterprises, among other occasions
