Although the surface mount is better than the direct mount, the brightness of the surface mount LED display is low, and the waterproof, moisture, and ultraviolet protection functions cannot meet the requirements of harsh outdoor environments. The world of plug-in LED devices. Full-color surface-mount LED display can only be used in large numbers indoors. The application technology of surface-mount LED can not meet the requirements of outdoor, the outdoor hot and cold environment is extremely prone to dead lights.

Surface mount LED display advantages

1. The brightness and protection level of SMD are superior to in-line technology. People have higher requirements on the surface-to-surface definition, which promotes the continuous development of small-pitch technology. The ultra-high refresh rate of the small-pitch surface-mount screen makes the screen display more delicate and true.

2. The light mixing effect is good. RGB three chips in one, high-power LED requires back heat dissipation, it is more difficult to achieve direct insertion, and the brightness, red, green and blue of three angles match well at any angle, and the colors are vivid and vivid.

3. The product is thinner and lighter, easy to install quickly The die-cast aluminum cabinet is thin, light, and high-precision. It is a simple upgrade of the traditional LED display cabinet. It has been comprehensively optimized and updated in terms of structure and performance. It is very convenient to disassemble and maintain.

4. The automatic placement machine is used for automatic production, which is beneficial to large-scale installation and production. It has small volume and fewer consumables. It 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, because the design structure is three-in-one and the full-color SMD size is small, the light-emitting area is small and the black area is large, which improves the contrast 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 began to develop rapidly. Moreover, there are mature outdoor surface-mount display screens in the market. Lianchengfa also has its own series of outdoor surface-mount LED screen products, including P4, P5, P6, P7.62, P8, P10 and so on.
