RGB common cathode LED, also known as RGB common cathode light-emitting diode, is a type of LED that is widely used in various applications due to its rich color mixing capabilities and low cost. In this article, we will introduce the basic concepts, characteristics, applications, and future development trends of RGB common cathode LED in the industry.

Basic Concepts of RGB Common Cathode LED

RGB common cathode LED is a type of LED that uses three different colors of light-emitting diodes (LEDs) - red, green, and blue - to mix and produce various colors. The term "common cathode" refers to the fact that the cathodes of the three LEDs are connected together and connected to the negative terminal of the power supply. This is different from the "common anode" type, where the anodes of the three LEDs are connected together and connected to the positive terminal of the power supply.

Characteristics of RGB Common Cathode LED

RGB common cathode LED has the following characteristics:

• Color mixing ability: By adjusting the brightness of the red, green, and blue LEDs, a wide range of colors can be generated, making it suitable for applications such as full-color displays, stage lighting, and decorative lighting.
• Low cost: RGB common cathode LED is relatively low-cost compared to other types of LED, which makes it more accessible for mass production and widespread application.
• Small size: RGB common cathode LED has a small size, which makes it suitable for applications with limited space, such as mobile devices, smart home, and wearable devices.
• High brightness: With the continuous development of technology, the brightness of RGB common cathode LED has been greatly improved, which can meet the needs of various applications.
