Surface Mount Display LED (SMD LED) technology has revolutionized the display industry, offering a compact, energy-efficient, and cost-effective solution for various applications. This article aims to provide an in-depth introduction to SMD LED technology, covering its history, advantages, applications, and future trends.

History of SMD LED Technology

The concept of surface mount technology (SMT) was first introduced in the 1960s, and it gradually evolved over the years. In the early 1970s, SMT started to gain popularity in the electronics industry due to its ability to reduce the size and weight of electronic devices. However, it was not until the late 1980s that SMD LED technology began to emerge as a viable alternative to traditional LED packages. The first SMD LED packages were developed by Nichia Corporation in Japan. These packages featured a flat, rectangular shape and were designed to be mounted directly onto a printed circuit board (PCB). Over the years, SMD LED technology has undergone significant advancements, leading to the development of various types of packages, such as COB (Chip-on-Board), SMD3528, SMD5050, and more.
