Here, we teach you how to pay attention to what problems you should pay attention to in the actual purchase, so as to maximize the application rate of your own investment on the premise of meeting the application needs.

For small-pitch LED displays, the smaller the dot pitch, the higher the resolution, and the higher the resolution, the stronger the clarity of the picture, which is the focus of manufacturers' marketing for small-pitch displays. However, in practice, industry users want to build the best small-pitch LED display system. While paying attention to the resolution of the screen itself, they should also consider its matching with the back-end signal transmission products.

Since there are various formats of video signals on the market, small-pitch LED screens cannot support all of them. Therefore, when users buy small-pitch LED screens, they must choose according to their needs, and should not consciously chase the trend to prevent the waste of resources.

The second secret: When choosing the dot pitch of the LED display, you need to pay attention to the balanced effect and technology.

Compared with the traditional LED display, the most prominent feature of the small-pitch LED display is that the dot pitch is smaller. We all know that in practical applications, the smaller the dot pitch of the display screen, the higher the pixel density, the more information capacity that can be displayed per unit area at one time, and the closer the viewing distance is. On the contrary, the longer the suitable viewing interval is. Therefore, in view of the popularity of the concept of small-pitch display screens, many industry users naturally think that the smaller the dot pitch when purchasing display products, the better, but this is not the case.

In order to achieve the best visual effect, the display has the best viewing distance, and the small-pitch LED display is no exception. If industry users want to stop simple measurement, there is an established formula, that is, the best visual interval = point spacing/0.3~0.8. It should be known that the smaller the dot pitch, the higher the cost of the small-pitch display screen. Therefore, in the actual purchase, users should comprehensively consider their own costs, needs, and application scope.

The third secret: When choosing the brightness of the display, "low brightness and high gray" is the prerequisite.

In order to ensure the warmth of people's viewing, the first thing that users need to pay attention to when purchasing small-pitch products is brightness. According to relevant researches, in terms of human eye sensitivity, the brightness of LEDs is twice that of passive light sources (projectors and liquid crystal displays). Between 100cd/m2-300cd/m2. However, in the traditional LED display technology, reducing the brightness of the screen will cause a loss of grayscale, and the loss of grayscale will directly affect the picture quality. Therefore, an important criterion for high-quality small-pitch LED screens is to achieve the technical indicators of "low brightness and high gray".

In the actual purchase, users can follow the principle of "the more brightness levels the human eye can recognize, 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. The more brightness levels of the display, the larger the chromaticity space of the display, and the greater the potential for displaying rich colors.

The above is the relevant purchase experience of LED display manufacturer Liancheng Fa (LCF) on small-pitch LED display for many years. I hope it can help more friends in the purchase of small-pitch LED display.
