Why do you seldom use surface-mounted LED displays outdoors?

Date: 2019-12-13

Outdoor full color screens are commonly used in-line products at present. Why don't you often use surface-mounted LED products? Although surface mount is better than in-line mount in display effect, outdoor full-color display screen is the world of in-line led devices due to low brightness of surface mount LED display screen and its waterproof, moisture-proof and ultraviolet protection functions cannot meet the requirements of outdoor harsh environment. The full-color surface-mounted LED display screen can only be widely used in households. The application technology of surface-mounted LED still cannot meet the outdoor requirements, and the outdoor cold and hot environment is extremely prone to dead lights.

Advantages of surface-mounted LED display

1. The product is thinner and lighter, and is convenient for quick installation. Die-cast 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. It is extremely convenient to disassemble, assemble and maintain.

2. Good light mixing effect. RGB three chips are three-in-one. High-power LED needs back heat dissipation, which is difficult to realize if it is inserted directly into the LED. In addition, the three brightness matching of red, green and blue are consistent and vivid in color at any angle.

3. The brightness and protection level of SMD are better than those of direct insertion. People have higher requirements for the definition of surface stickers, prompting the continuous development of small-pitch technology. Small-pitch surface stickers have ultra-high refresh rate, and the picture display is more high-definition, exquisite and real.

4. Automatic production of full-automatic chip mounter is beneficial to large-scale installation and production, with small volume and less consumables. It has the advantages of wave soldering during processing, high production efficiency and improved product quality.

5. The connectors shall be professional aviation plugs with guaranteed quality and safety. In addition, due to the three-in-one design structure and the small size of full-color SMD, the luminous area is small and the black area is large, thus improving the contrast ratio of the LED display screen.

At present, with the progress 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 obtain rapid development. At present, the market already has mature outdoor surface-mounted display screens.
