Knowledge of small pitch LED display

Date: 2019-12-17

• With the continuous development and improvement of LED technology, indoor LED displays, especially small-pitch products, comply with market demand and energy saving with their seamless splicing, low brightness and high gray, high refresh rate, ultra high definition, low energy consumption, and long life. The characteristics of economic development advantages have been widely used in: power production dispatch control center, military command and control center, city management emergency command center, traffic management command center, industrial process control display system, radio and television display and monitoring system, shopping malls, hotels, Communication information display system, financial securities information display system, government enterprise multimedia video conference display system, mining safety production monitoring system, urban environment monitoring command system, fire control, meteorology, maritime flood control command system, airport and subway flight display, security monitoring system, etc. Broad field.
  

  

  
  

  How to define 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 point distance. The display industry generally adopts the method of defining product specifications based on the distance, such as our commonly used P16, P10, P8 (the dot pitch is 16mm, 10mm, and 8mm respectively). As the process progresses, the dot pitch becomes smaller and smaller. . According to industry consensus, displays with a dot pitch of less than 3 mm are small pitches. In the current mass-produced displays, the minimum dot pitch is P1.6, which means that the distance between the center points of two lamp beads is only 1.6mm.
  
  
  What are the advantages of small pitch LED displays?
  
  
  1.Seamless stitching
  The splicing large screen display technology can't avoid the influence of the physical frame when satisfying the customer's needs to the greatest extent. Even the ultra-narrow-edge DID professional LCD screen still has very obvious stitching seams. Only the LED display screen makes the stitching after stitching reach zero Seam requirements, high-density small-pitch led seamless splicing advantages are highlighted.
  
  2.High brightness intelligent adjustable
  The led screen itself has high brightness. In order to meet the viewing effect in a strong light environment and a dark light environment, and avoid visual fatigue, it can be adjusted with the light sensing system.
  
  3.Higher gray scale for better color performance
  Even under low brightness, the grayscale performance of the display is almost perfect, and the displayed layering and vividness of the display are higher than that of the traditional display. It can also display more image details and no information loss.
  

  

  
  

  
  4.High contrast, faster response speed, high refresh frequency
  The number of times 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 the image flickers and jitters, and the faster your eyes become tired. Under the high refresh, the LED small-pitch screen has stable ingested images, no ripple black screen, clear image edges, and accurately restores the true information of the image.
  

  

  

  
  
  5, natural color reproduction
  Adopting the international leading point-by-point correction technology, using the principle of LED light emission, to completely retain the authenticity of colors, avoiding other display technologies such as backlight projection materials, color loss and deviation caused by the light running path, and achieve true color reproduction .
  

  

  
  

  
  6.Three-dimensional visual experience
  When customers choose to adopt the 3D playback mode, the mosaic wall will present shocking high-definition images, no matter live TV, exhibitions, or digital advertisements, they can fully perform the wonderful vision and let the audience enjoy an extraordinary visual experience.
  
  
  In summary, after you have a preliminary understanding of the small-pitch LED display, how do you choose the LED small-pitch display? Jinghui summarizes the following three points for you:
  
  
  1. 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 application environment and program budget when purchasing products to avoid the dilemma of spending a lot of money but not achieving the expected results.

  
  

  
  

  2. Maintenance cost:
  When users choose LED small-pitch display products, not only the purchase cost, but also high maintenance costs must be considered. In actual operation, the larger the size of the screen body, the more complicated the maintenance process, and the maintenance cost will naturally increase accordingly. In addition, the power consumption of small pitches is not easily reduced, and the operating cost of large-sized LED small-pitch display screens is usually higher.
  
  3. LED small pitch signal transmission compatibility is very important:
  The indoor signal access of led small-pitch display screens has diverse requirements, large numbers, scattered locations, multi-signal display on the same screen, and centralized management. In actual operation, for efficient use of display screens, signal transmission equipment must not be taken lightly. In the display market, not all LED small-pitch displays can meet the above requirements. When choosing a product, do not pay attention to the resolution of the product, and fully consider whether the existing signal equipment supports the corresponding video signal and after-sales service.
