Rectangular LED, also known as rectangular light-emitting diode, is a type of LED with a rectangular shape. As an essential component in various industries, rectangular LED has been widely used in lighting, display, and other fields. This article will introduce the rectangular LED industry, including its history, types, applications, and market trends.

History of Rectangular LED

The invention of the LED can be traced back to the 20th century. In 1907, Henry Joseph Round, an English physicist, discovered that when a semiconductor is subjected to an electric field, it can emit light. However, it was not until the 1960s that the LED was successfully developed and applied. Since then, LED technology has been continuously improved, and rectangular LED has become an important part of the LED industry. In the early days, rectangular LED was mainly used in indicator lights and displays. With the continuous development of technology, the application of rectangular LED has been expanded to various fields, such as lighting, automotive, medical, and communication.

Types of Rectangular LED

Rectangular LED can be divided into several types according to the materials, structures, and light-emitting colors. 1. Materials: Rectangular LED can be divided into two types according to the materials used: inorganic and organic. Inorganic rectangular LED is mainly made of inorganic materials such as silicon, gallium arsenide, and zinc sulfide. Organic rectangular LED is mainly made of organic materials such as polyfluorene and polyphenylene vinylene. 2. Structures: According to the structure, rectangular LED can be divided into two types: single-layer and multi-layer. Single-layer rectangular LED has a simple structure, while multi-layer rectangular LED has a complex structure, which can achieve better light-emitting performance. 3. Light-emitting colors: Rectangular LED can emit various colors of light, including red, green, blue, yellow, and white. Among them, white rectangular LED is the most widely used due to its high brightness and wide application range.
