Advantages and disadvantages of SMD technology outdoor surface mount LED display
So, what is SMD technology? The full name of SMD is Surface Mounted Devices, which means: Surface Mounted Devices, which is one of the SMT (Surface Mounted Technology) components. “In the early stages of electronic circuit board production, via assembly was done entirely by hand. When the first automated machines came out, they could place some simple lead components, but complex components still required manual placement for wave soldering. Surface mount components were introduced 20 years ago, ushering in a new era. From passive components to active components and integrated circuits, all eventually became surface mount devices (SMD) and can be assembled by pick and place equipment . For a long time, it was believed that all lead components could eventually be packaged in SMD. So SMD technology is widely used in LED displays.
In the three-in-one full-color LED display, one of the three-in-one SMD technology refers to encapsulating SMT lamps with three different colors of RGB LED chips in the same colloid according to a certain spacing. The full-color LED display with SMD technology has a large viewing angle, and the surface can be treated with light diffuse reflection. The resulting effect is not granular and has good color uniformity. In terms of color, the three-in-one full-color spectroscopic color separation is easier than the three-in-one, and the color saturation is high. The three-in-one uses the entire surface to emit light, so the overall color of the three-in-one is more uniform. The overall flatness of the three-in-one is easier to control. It has always been the standard technology used in high-definition full-color LED displays.
In the past, due to the complex manufacturing process and difficult maintenance, the cost was very high, and it was generally used for high-end LED display products. However, with the advancement of technology in recent years, the cost is relatively within an acceptable range. Lianchengfa also has its own relatively mature outdoor surface mount products, including: P6.944, P7.62, P8, P10, p12, etc.
