Why are Surface Mount LED Displays Rarely Used Outdoors?

  Outdoor full-color screens are currently commonly used in-line products. Why not often use surface mount LED products?


  Although the display effect is better than the direct plug-in, the brightness of the surface-mounted LED display is low, and the waterproof, moisture-proof and UV-proof functions cannot meet the requirements of the harsh outdoor environment, so the outdoor full-color display is a direct The world of plug-in LED devices. The full-color surface mount LED display can only be widely used indoors. The application technology of surface mount LED can not meet the requirements of outdoor, and the outdoor hot and cold environment is very prone to the phenomenon of product dead lights.


Surface mount and in-line LED display box structure comparison


      Surface mount LED display advantages:


      1. The brightness and protection level of SMD are superior to direct plug-in. People have higher requirements for the clarity of surface mounts, which promotes the continuous development of small-pitch technology. The small-pitch surface mount screen has an ultra-high refresh rate, and the screen display is more high-definition, delicate and true.


      2. Good mixing effect.

The RGB three chips are three in one, and the high-power LED needs heat dissipation from the back, which is difficult to achieve if it is plugged in directly, and the three brightness matching consistency of red, green and blue is good at any angle, and the colors are vivid and vivid.


      3. The product is lighter and thinner, easy to install quickly

      The die-casting aluminum box is thin, light in weight and high in precision. It is a simple upgrade of the traditional LED display box. It has been comprehensively optimized and updated in terms of structure and performance, and is extremely convenient for disassembly, assembly and maintenance.


      4. The automatic placement machine performs automatic production, which is conducive to large-scale installation and production, small size and few consumables, and has the advantages of wave soldering during processing, high production efficiency, and improved product quality.


      5. The connectors use professional aviation plugs, and the quality and safety are guaranteed.

      In addition, due to the three-in-one design structure and the small size of the full-color SMD, the light-emitting area is small and the black area is large, which improves the contrast ratio of the LED display.

      At present, with the advancement of LED chip technology and LED packaging technology, the brightness and protection level of SMD have begun to meet the requirements of outdoor applications and have begun to develop rapidly. Moreover, there are already mature outdoor surface mount displays in the market, and Lianchengfa also has its own outdoor surface mount LED screen series products, including P4, P5, P6, P7.62, P8, P10, etc.
