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

Development History of RGB Common Cathode LED

The development of RGB common cathode LED can be traced back to the 1960s. At that time, LED technology was still in its infancy, and the color of the LED was limited to red, green, and yellow. With the continuous development of LED technology, the color range of LED has been expanded, and the RGB common cathode LED has emerged as a new type of LED. In the 1980s, the RGB common cathode LED began to be used in the field of display. At that time, the color display screen was still in the stage of development, and the RGB common cathode LED played an important role in the realization of color display. In the 1990s, with the continuous improvement of LED technology, the color quality and brightness of RGB common cathode LED were greatly improved, and its application range was further expanded. In the 21st century, the RGB common cathode LED has become an indispensable part of the display industry. With the continuous development of display technology, the RGB common cathode LED has also been constantly innovated and developed, and has become an important driving force for the development of the display industry.

Working Principle of RGB Common Cathode LED

The working principle of RGB common cathode LED is based on the principle of color mixing. It uses three primary colors, red, green, and blue, to mix and produce a variety of colors. The following is the specific working principle: 1. Red, green, and blue LED chips are packaged together on a common cathode substrate. 2. By controlling the current input to each LED chip, the brightness of each color can be adjusted. 3. When the red, green, and blue LED chips are turned on at the same time, the three colors mix to form white light. 4. By adjusting the brightness of each color, a variety of colors can be produced. The RGB common cathode LED has the advantages of high brightness, good color saturation, and low power consumption. It is widely used in various fields.
