This article will introduce the industry of high power violet LED, including its development history, market status, application fields, and future prospects.

Development History of High Power Violet LED

The development of high power violet LED can be traced back to the 1960s. At that time, scientists began to study the properties of gallium nitride (GaN) as a new semiconductor material. In the 1970s, the first violet LED based on GaN was successfully developed. However, due to the limitations of material quality and technology, the brightness and efficiency of the LED were relatively low. With the continuous development of material science and technology, the performance of high power violet LED has been greatly improved.

In the 1990s, the development of MOCVD (Metal Organic Chemical Vapor Deposition) technology greatly promoted the production of high-quality GaN epitaxial films. As a result, the brightness and efficiency of high power violet LED were significantly improved. In the 2000s, the application of high power violet LED began to spread in the market, and its performance has been continuously optimized.
