Revolutionizing Lighting Design: The Versatile RGB Common Cathode LED

RGB Common Cathode LED, also known as Red, Green, and Blue Common Cathode LED, is a type of LED display technology that uses a single anode and three cathodes. This technology is widely used in various fields, such as home appliances, automotive, and industrial applications. In this article, we will introduce the RGB Common Cathode LED industry, including its definition, working principle, types, applications, and market trends.

Definition and Working Principle of RGB Common Cathode LED

RGB Common Cathode LED refers to an LED with three colors, red, green, and blue, sharing a common cathode. In the LED structure, the cathode is the negative pole, and the anode is the positive pole. In a common cathode LED, the three colors share the same cathode, while each color has its own anode.

The working principle of RGB Common Cathode LED is based on the color mixing principle. When red, green, and blue light are mixed in different proportions, they can produce a variety of colors. By controlling the current passing through each color, the brightness and color of the LED can be adjusted. This technology is widely used in full-color displays, such as LED screens, LED lights, and LED modules.
