RGB common cathode LED, also known as RGB negative pole LED, is a type of LED that uses a common cathode structure. It is widely used in various fields such as lighting, display, and electronic products. In this article, we will introduce the industry of RGB common cathode LED, including its working principle, application fields, market trends, and future development prospects.

Working Principle of RGB Common Cathode LED

RGB common cathode LED is composed of three primary colors: red, green, and blue. Each color has its own LED chip, and they are connected in series. The common cathode refers to the negative pole of all the LED chips being connected together. When an electric current passes through the LED chips, the electrons will be emitted from the cathode to the anode, and the light will be emitted through the semiconductor layer. By controlling the current through each color, we can achieve various colors and brightness levels.
