The common cathode design principle refers to a power supply method used in LED display panels, also known as common cathode power supply. In this design, the negative terminals of the red, green, and blue (R, G, B) LED chips are connected together, while the positive terminals are controlled by the control circuit. By precisely allocating different current and voltage to the R, G, B chips, optimal performance and energy efficiency can be achieved, resulting in superior display effects.
The essence of common cathode design lies in supplying power to the R, G, B chips separately, as they require different operating voltages and currents. Adopting the common cathode power supply method allows the current to pass through the chips before reaching the IC negative terminal, effectively reducing forward voltage drop and decreasing conduction resistance. As a result, the LED display panel can achieve higher brightness and improved reliability.
Compared with the common anode technology, common cathode technology connects the anodes of the diodes together and drives them by the cathode. This technology effectively reduces energy consumption and enhances the display performance, making it widely utilized in the field of LED display panels.
