RGB common cathode LED, also known as red, green, and blue common cathode LED, is a widely used type of LED in various applications, including lighting, display, and indicator. This article will provide an in-depth introduction to the RGB common cathode LED industry, covering its history, technology, applications, market trends, and future prospects.

History of RGB Common Cathode LED

The development of RGB common cathode LED can be traced back to the 1960s when the first LED was invented. In the early stages, LEDs were mainly used for indicator purposes. It was not until the 1970s that the concept of RGB LED was proposed, which allowed for the creation of full-color displays. With the advancement of technology, RGB common cathode LED has become an essential component in various industries.

Technology of RGB Common Cathode LED

RGB common cathode LED is a type of LED that has a common cathode, meaning that the anode of each color (red, green, and blue) is connected to the cathode of the other two colors. This configuration allows for a simpler circuit design and lower power consumption compared to other LED configurations. The basic structure of an RGB common cathode LED consists of three semiconductor chips, each emitting red, green, and blue light, respectively. These chips are encapsulated in a single housing and connected to a single anode. When current passes through the LED, the semiconductor chips emit light of different colors, allowing for the creation of various colors and shades. The color and brightness of an RGB common cathode LED can be controlled by adjusting the current passing through each semiconductor chip. By mixing different intensities of red, green, and blue light, a wide range of colors can be achieved.
