In the current era, in the field of LED displays, small-pitch LED displays have become a well-deserved star product, and the scale of its application market is developing very rapidly. However, despite the marketing plans of various manufacturers, many industry users are no strangers to small spacing, but they still cannot control how to choose products that suit them.

 

Here, we teach you how to pay attention to what issues should be paid attention to in the actual purchase, so as to maximize the utilization rate of your own investment on the premise of meeting application needs. The following is the small spacing introduced by Lianchengfa to our friends. Some tips for buying LED displays.

 

1: When selecting the display brightness, "low brightness and high gray" are the prerequisite factors.

 

In order to ensure people's viewing comfort, the first thing that users need to pay attention to when buying small-pitch products is the brightness problem. According to relevant research, the brightness of LED display screen is 3 times that of passive light source (projector and liquid crystal display) in terms of human eye sensitivity. However, in order to ensure the comfort of human eyes, the brightness range of small-pitch display is only It can be between 200cd/m3-400cd/m2. However, in the traditional LED display technology, reducing the brightness of the screen will cause the 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 "low brightness and high gray" technical indicators.

 

In the actual purchase, users can follow the principle of "the more brightness levels that 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 higher the brightness level, the greater the chromaticity space of the display screen, and the greater the potential for displaying rich colors.

 

2: Pay attention to the balance effect and technology when choosing the pixel pitch of the display.

 

Compared with the traditional display screen, the small-pitch display screen has the most prominent feature 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 per unit area can be displayed at one time, and the closer the distance suitable for viewing. On the contrary, the distance suitable for viewing is farther. Therefore, in view of the popularity of the concept of small-pitch display screens, many users in the industry naturally think that the smaller the dot pitch, the better when purchasing display products, but this is not the case.

 

If the display screen wants to achieve the best visual effect, it has the best viewing distance, and the small-pitch LED display is naturally no exception. If industry users want to make simple calculations, there is an established formula, that is, the best visible distance = dot pitch/0.5~0.9. It should be known that the smaller the dot pitch, the higher the cost of the small-pitch display. Therefore, in actual purchase, users must comprehensively consider their own costs, needs, and application scope.

 

3: When choosing the display resolution, 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 stronger the clarity of the picture. This is exactly the core of the LED display manufacturers' marketing of small-pitch displays. . However, in actual operation, industry users want to build the best small-pitch LED display system. While paying attention to the resolution of the screen itself, they must also consider the combination of it and the back-end signal transmission product.

 

Since there are multiple formats of video signals on the market, small-pitch LED screens cannot support them all. Therefore, users must choose according to their needs when purchasing small-pitch LED screens, and avoid blindly following the trend to avoid waste of resources.
