SMD LED display screen refers to an LED display screen packaged with SMD (Surface Mounted Devices, surface mount device) technology. Specifically, SMD technology is a technology that directly mounts electronic components (such as LED lamp beads) on the surface of a printed circuit board (PCB), and connects the components to the circuit board through welding and other methods.
LED displays using SMD packaging have the following characteristics:
1. Packaging method: SMD-packaged LED displays encapsulate lamp cups, brackets, wafers, leads, epoxy resin and other materials into lamp beads of different specifications, and the lamp beads are welded through processes such as high-speed placement machines and high-temperature reflow soldering. On the circuit board, display units with different spacings are made.
2. High transparency: Since SMD packaging technology can achieve smaller LED lamp bead spacing and higher pixel density, SMD LED display screens have higher transparency and can present clearer and more delicate image effects.
3. Lightweight and flexible: SMD LED display is light in weight, flexible in structure, easy to install and disassemble, and is suitable for various scenarios and application needs.
4. High efficiency and energy saving: SMD packaged LED lamp beads have high luminous efficiency and low power consumption, so the SMD LED display has a long service life and low maintenance costs.
SMD LED display screens are widely used in indoor commercial displays, billboards, stage displays, information release, security monitoring, virtual reality and simulators, etc., and have become an important support for the development of informatization, digitization, and intelligence in modern society.
