How to define the LED small pitch?
We all know that led is composed of led lamp beads, and the distance between the center points of two led lamp beads is called the dot pitch. The display industry generally uses the method of defining product specifications according to the distance, such as our commonly used P12, P10, P8 (dot pitches are 12mm, 10mm and 8mm respectively), etc. As the process progresses, the dot pitch is getting smaller and smaller . According to the consensus of the industry, displays with a dot pitch of less than 3 mm are small pitches. In the current mass-produced display screens, the minimum dot pitch is P1.6, that is, the distance between the center points of the two lamp beads is only 1.6mm.

What are the advantages of small-pitch LED displays?
1. Seamless splicing
The splicing large-screen display technology can not avoid the influence of the physical frame when it meets the needs of customers to the maximum. Even the ultra-narrow-edge DID professional LCD screen still has very obvious splicing seams. Only the LED display makes the splicing seam impossible. Seam requirements, the advantages of seamless splicing of high-density small-pitch leds can be highlighted.
2. Intelligent adjustable high brightness
The led screen itself has high brightness, in order to meet the comfortable viewing effect for the viewer in the strong light environment and the dark light environment, and to avoid visual fatigue, the brightness can be adjusted with the light sensing system.
3. High gray level and better color performance
Even at low brightness, the grayscale performance of the display screen is almost perfect, and the level and vividness of the displayed picture is higher than that of the traditional display screen. It can also show more image details without loss of information.

4. High contrast, faster response speed and high refresh frequency
The number of times that the electron beam repeatedly scans the image on the screen. The higher the number of scans, the higher the refresh rate, and the better the stability of the displayed image (picture). The lower the refresh rate, the more flickering and shaking the image, and the faster the eyestrain. Under high refresh rate, the small-pitch LED screen can capture images stably, without ripples and black screens, with clear image edges, and accurately restore the true information of the image.

5. Naturalization of color restoration
Adopting the internationally leading point-by-point correction technology, using the LED light-emitting principle, to completely retain the authenticity of the color, avoiding the color loss and deviation caused by other display technologies such as the material of the backlight projection and the light running path, and realizing the true color reproduction .

6. Three-dimensional visual experience
When the customer chooses to use the 3D playback mode, the splicing wall will present shocking high-definition images. Whether it is live TV, exhibition display, or digital advertising, it can fully interpret the wonderful vision, allowing the audience to enjoy an extraordinary visual experience.

How to choose small LED pitch?
The size and resolution of the dot pitch:
The size and resolution of the dot pitch are the most important factors when people buy. In actual operation, the smaller the dot pitch, the higher the resolution, and the better the actual application effect. The smaller the dot pitch of LED small-pitch display products, the higher the resolution and the higher the price. Users should fully consider their own application environment and program budget when purchasing products to avoid the dilemma of spending a lot of money but not achieving the expected results.
Maintenance cost:
When users choose LED small-pitch display products, not only the purchase cost, but also the high maintenance cost must be considered. In actual operation, the larger the screen size, the more complicated the maintenance process, and the maintenance cost will naturally increase accordingly. In addition, the power consumption of a small pitch is not easy to become smaller, and the operating cost of a large-size LED small pitch display is usually higher.
LED small pitch signal transmission compatibility is very important:
The indoor signal access of the led small-pitch display has the requirements of diversification, large number, scattered locations, multi-signal display on the same screen, and centralized management. In actual operation, if the display is to be used efficiently, the signal transmission equipment must not be underestimated. In the display market, not all LED small-pitch displays can meet the above requirements. When purchasing products, do not pay attention to the resolution of the product one-sidedly, and fully consider whether the existing signal equipment supports the corresponding video signal and after-sales service.
