Abstract: We often see display screens with such words as: High-quality SMD technology, imported high-end materials, high-quality special-purpose IC chips... Unfamiliar customers will certainly ask what SMD technology is.

So, what is SMD technology? SMD's full name is SurfaceMountedDevices, which means: surface mount devices, which is one of SMT (Surface Mount Technology) components. “In the initial stage of electronic circuit board production, via assembly is completely done by hand. After the first automated machines are introduced, they can place some simple lead components, but the complex components still need manual placement to perform wave soldering. Surface mount components have been introduced 20 years ago and have created a new era of this, from passive components to active components and integrated circuits, all of which have finally become surface mount devices (SMDs) and can be assembled by pick and place equipment. For a long time, people thought that all the pin components could be finally packaged in SMD, so SMD technology is widely used in LED display.
In the three-in-one full-color LED display, one of the three-in-one SMD technology is to encapsulate three different color LED chip SMT lamps in the same glue body with a certain spacing. The full-color LED display of SMD technology has a larger viewing angle, and the surface can be treated with diffuse reflection. The effect is not granular, and the uniformity is good. From the color point of view, three-in-one full-color spectrophotometric separation is easier than three, 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 three-in-one overall flatness is easier to control. Has been the standard technology used in high-definition full-color LED display.
In the past, because of complicated manufacturing processes 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 has been relatively acceptable, such as more mature outdoor surface mount products, including: P6, P8, P10, etc..
