How to choose a small pitch LED screen?
Small pitch LED indoor application, "low light and high gray" is the premise In order to ensure the comfort of viewing, the first thing users should pay attention to when purchasing small-pitch LED products is the brightness problem. Related research shows that from the perspective of human eye sensitivity, the brightness of LED (active light source) is twice that of passive light source (projector and liquid crystal display), and to ensure the comfort of human eyes, small-pitch LED display The brightness range can only be between 100 cd/m2 and 300 cd/m2. However, in the traditional LED display technology, reducing the brightness of the screen will cause loss of gray scale, and the loss of gray scale will directly affect the picture quality. Therefore, an important criterion for the high-quality small-pitch LED screen is to achieve "low" Bright and high gray" technical indicators. In the actual purchase, the user can follow the principle that “the more the brightness level can be recognized by the human eye, the better.†The so-called brightness level refers to the brightness level of the image that can be distinguished by the human eye from the darkest to the whitest, which is recognized. The higher the brightness level, the greater the color space of the display, and the greater the potential for displaying rich colors. Regarding the choice of point spacing, pay attention to balance effect and technology Compared to traditional LED displays, the small pitch LEDs feature a smaller dot pitch. In practical applications, the smaller the dot pitch is, the higher the pixel density is, and the more information capacity that can be displayed per unit area at a time, the closer the distance suitable for viewing, and vice versa, the farther the distance is suitable for viewing. In view of the hot concept of small-pitch LEDs, many industry users naturally think that the smaller the dot pitch of the purchased products, the better. However, this is not the case. In order to achieve the best visual effect, the LED display has the best viewing distance, and the small-pitch LED display is no exception. If the industry user wants to make a simple calculation, there is an established formula, that is, the best visual distance = point spacing / 0.3 ~ 0.8. It should be known that the smaller the dot pitch is, the higher the cost of the small-pitch LED display. Therefore, in actual purchase, the user should comprehensively consider its own cost, demand, application range and other factors. Resolution selection, pay attention to the matching with the back-end signal transmission equipment For small-pitch LED displays, the smaller the dot pitch, the higher the resolution, and the higher the resolution, the higher the sharpness of the image, which is exactly the marketing focus of the manufacturer for small-pitch LEDs. However, in practice, industry users want to build the best small-pitch LED display system, while paying attention to the screen's own resolution, but also consider its combination with the back-end signal transmission products. For example, in the security monitoring application, the front-end monitoring system generally includes 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 the above. The video signal of the format, therefore, in order to avoid the waste of resources, the user must select the on-demand when purchasing the small-pitch LED screen, and should not blindly catch up with the trend. Conclusion: At present, the small-pitch LED display is still in the initial stage of development. In order to obtain higher market attention, technological innovation has become an important selling point. Therefore, in terms of spacing technology, “no minimum and only smaller†has become the mainstream trend of the industry. This invisibly raises the concern of industry users on the spacing. In actual purchases, it is easy to pay too much attention to catching up with the trend, ignoring other factors. To put it simply, a cost-effective small-pitch LED system is a synergistic effect of many factors, and the three aspects highlighted in this paper are the objects that users focus on in their purchase.
