Small spacing LED display knowledge summary

2021/01/26

With the continuous development and improvement of LED technology, indoor LED display screen, especially small-spacing products, has been widely used in the following fields:Power production scheduling control center, military command and control center, city emergency command center, traffic management command center, industrial process control display system, radio and television shows and monitoring system, shopping malls, hotels, communication information display system, financial securities, information display system, government enterprises multimedia video conference system, mine safety production monitoring system and city environmental monitoring command system, fire protection, meteorology, maritime flood control and command system, airport, subway flight display, security monitoring system, etc.

How to define LED small spacing?

We all know that LED is composed of LED beads, and the distance between the center points of two LED beads is called point spacing.The display industry generally uses the method to define product specifications according to the size of the distance, such as P12, P10, P8 (point spacing is 12mm, 10mm and 8mm respectively), etc. With the progress of the process, the point spacing becomes smaller and smaller.According to the industry consensus, dot spacing less than 3 mm display for small spacing.In current mass-produced displays, the minimum dot spacing is P1.6, which means the distance between the center points of the two bead is only 1.6mm.

What are the advantages of small spacing LED display

Seamless splicing

The splicing large screen display technology can not avoid the influence of the physical frame when Z maximally meets the needs of customers. Even if the ultra-narrow edge DID professional LCD screen, there are still very obvious splicing seams. Only the LED display makes the splicing seam meet the requirements of seamless, and the advantages of high density and small spacing LED seamless splicing are highlighted.

High brightness intelligent adjustable

LED screen has high brightness. In order to provide viewers with comfortable viewing effect in strong light environment and dark light environment and avoid visual fatigue, brightness adjustment can be carried out with the light sensing system.

Higher grayscale level for better color performance

Even if the gray level of the display is almost perfect under the low brightness, the level and brightness of the display are higher than that of the traditional display, and the image can be displayed with more details without information loss.


High contrast, faster response speed and high refresh frequency

The number of times the electron beam scans the image on the screen repeatedly. The higher the scanning number, the higher the refresh rate, and the better the stability of the displayed image (picture).The lower the refresh rate, the more the image flickers and shakes, and the faster the eye strain.LED small spacing screen under high refresh, stable image intake, no corrugated black screen, image edge clear, accurate restoration of the real information of the image.

The color reverts to nature

Adopts point-by-point correction technology, utilizes LED luminescence principle, completely retains the authenticity of the color, avoids the color loss and deviation caused by other display technology such as backlight projection material, light running path, and realizes the true sense of color reproduction.

The visual experience is three-dimensional

When customers choose to use 3D broadcast mode, splicing wall will present shocking high-definition images, whether TV broadcast, exhibition display, or digital advertising, can be incisively and vividly interpretation of the wonderful vision, let the audience enjoy the visual experience.

How to choose LED small spacing?

Point spacing size and resolution:

The size and resolution of the dot spacing is an important factor when people buy.In practical operation, the smaller the point distance, the higher the resolution, the better the practical application effect.The smaller the dot spacing of LED small-spacing display products, the higher the resolution, the higher the price.Users should consider their application environment and application budget when purchasing a product to avoid the dilemma of spending a lot of money but not achieving the desired results.

Maintenance Cost:

When choosing LED small-spacing display products, users should not only consider the purchase cost, but also consider the high maintenance cost.In practical operation, the larger the size of the screen, the more complex the maintenance process, and the maintenance cost will naturally increase accordingly.In addition, the power consumption of small spacing is not easily reduced, and the operating cost of large LED small spacing displays is usually higher.

LED small spacing signal transmission compatibility is very important:

The indoor signal access of LED small-spacing display screen has the requirements of diversification, large number, scattered location, multi-signal display with the screen, centralized management, etc. In actual operation, if the display screen wants to be used efficiently, the signal transmission equipment must not be ignored.In the display market, not all LED screens with small spacing can meet the above requirements.When choosing products, we should not pay one-sided attention to the resolution of products, and fully consider whether the existing signal equipment supports the corresponding video signal and after-sales service.
