First look at these three questions, and then talk about the small distance LED display selection
First look at these three questions, and then talk about the small distance LED display selection
Today's large screen display area, small distance LED display has become a well deserved hot, the application of the rapid rise in the market scale. For many industry users, although in the manufacturer's marketing bombing of small spacing is not new, but when it comes to how to choose their own products, still lack of confidence. Then, in the actual purchase, industry users should pay attention to what problems, in order to meet the application needs of the premise, to achieve a considerable utilization of their own investment?



Small distance LED display indoor applications, "low brightness, high ash" is a prerequisite
In order to ensure the comfort of viewing, users should first pay attention to the brightness when choosing the small distance LED display products. Research shows that, from the human eye sensitivity, LED (active light source) the brightness is passive light source (projectors and LCD) 2 times, and to ensure the comfort of the human eye, small pitch LED display screen brightness range only between 100 cd/m2-300 cd/m2. However, in the traditional LED display technology, reduce the brightness of the screen will cause the loss of intensity, and the loss of intensity will directly affect the picture quality, therefore, an important criterion of high quality small pitch LED display screen is to achieve low light high ash technical index.
In the actual purchase, the user can follow the brightness level of the human eye can better identify the principle of brightness level of so-called, refers to the human eye can distinguish the image from a black to white brightness level, more brightness level is identified, shows the color space display more colorful display potential the nature is also bigger.
Attention should be paid to balance effect and technology when choosing point spacing
In order to achieve fairly good visual effects, the LED display has a good visual range, and the small distance LED display screen is no exception. Industry users, if they want to make simple calculations, have an established formula, that is, pretty good visual distance = point spacing /0.3~0.8. You know, the smaller the point spacing, the smaller the distance LED display screen cost is higher, therefore, in the actual purchase, users should consider their own cost, demand, application range and other factors.
Compared with the traditional LED display, the small distance LED display is characterized by a smaller point spacing. In practical applications, the smaller the point spacing, the higher the pixel density, the more information capacity can be displayed per unit area, the closer the distance is for viewing, and the farther the distance is suitable for viewing. In view of the small distance LED display concept of fiery, many industry users naturally believe that the purchase of products, the smaller the point spacing, the better, however, this is not the case.
