Nowadays, in the field of LED display, small spacing LED display has become a well deserved hot spot, and the application market scale is rising rapidly. For users in many industries, although they are not unfamiliar with small spacing under the marketing bombing of manufacturers, they are still at a loss about how to choose their own products. Let me show you three points you should pay attention to when buying:
1、as for the selection of point spacing, we should pay attention to the balance effect and technology.
Compared with the traditional LED display screen
, the prominent feature of the small spacing full-color LED display screen is that the spacing between points is smaller. In practical applications, the smaller the point spacing, the higher the pixels per inch, the larger the information capacity that can be displayed per unit area at one time, and the closer the distance suitable for viewing; Otherwise, the farther away it is suitable to watch. In view of the popular concept of small spacing LED display, many industry users naturally believe that the smaller the product spacing, the better. However, this is not the case.
In order to achieve the best visual effect, the sight distance of LED display is the best, and the full-color LED display with small spacing is no exception. If industry users want to make a simple calculation, they have an established formula, that is, the best visible distance = distance between points /0.3~0.8. You know, the smaller the dot spacing, the higher the cost of LED display screen with smaller spacing. Therefore, in the actual purchase, users should consider their own costs, needs, application scope and other factors.
2、 Indoor application of small spacing LED display, "low brightness and high ash" is the premise.
In order to ensure viewing comfort, users should first pay attention to brightness when purchasing LED display products with small spacing. Relevant research shows that the brightness of LED (active light source) is twice that of passive light source (projector and LCD), and the brightness range of small spacing LED display screen can only be between 100 cd/m2 and 300 cd/m2, so as to ensure the comfort of human eyes. However, in the traditional LED display technology, reducing the brightness of the screen will cause the loss of gray, which will directly affect the image quality. Therefore, an important standard for judging high quality is to achieve the technical index of "low brightness and high gray scale" for small spacing LED display screen.
In actual purchase, users can follow the principle of "the more brightness levels that human eyes can recognize, the better". The so-called brightness level refers to the brightness level that the human eye can recognize from the darkest to the whitest image. The more brightness levels recognized, the larger the color space of the display screen, and the greater the potential to naturally display rich colors.
3、 the resolution selection should pay attention to the matching with the back-end signal transmission equipment.
For small spacing LED displays, the smaller the dot spacing, the higher the resolution and the higher the picture definition, which is the marketing focus of small spacing LED display manufacturers. But in fact, industry users want to build the best LED display system with small spacing. While paying attention to the resolution of the screen itself, they should also consider its matching with the back-end signal transmission products. To sum up, when choosing small spacing LED displays, users must choose according to their own needs to avoid blindly following the trend. The above is the purchasing knowledge brought by youcaixian. I hope you can help everyone.
Thank you for watching. Dylan, the manufacturer of LED display, will continue to work hard to do better!
