What is Common Cathode LED display technology?
Common Cathode is a patented LED driver architecture invented by SiliconCore that powers each red, green and blue diode with its own dedicated voltage. This precision power delivery eliminates excess heat generation at the PCB level, leading to cooler operating temperatures, lower energy consumption, higher brightness and longer display lifespan.
Why Common Cathode is Different
Traditional LED driver designs use a “Common Anode” approach, sending one uniform voltage to all diodes. This wastes energy and generates unnecessary heat. SiliconCore’s Common Cathode method:
Supplies precise voltages to each LED color channel
Reduces heat dissipation by 20–50%
Cuts power consumption by 20–40% vs. the industry average
Enables fanless operation, reducing noise and HVAC requirements
Extends LED lifespan to over 100,000 hours
Benefits of Common Cathode for LED Display Performance
| Benefit | How Common Cathode Delivers It |
|---|---|
| Higher Brightness | 40% higher sustained brightness with less power |
| Sustainability | Lower power usage reduces operational costs and carbon footprint |
| Cooler Operation | Safe to touch, even in high-brightness modes |
| Extended Lifespan | Reduced thermal stress preserves LED integrity for over 11 years |
| Better Image Quality | Higher dynamic range, improved low-light performance, and uniform color accuracy |
| XR & Broadcast Ready | Achieves 240Hz frame rates and 7680Hz refresh rates for multi-camera, slow-motion, and active 3D environments |
Sustainability Advantages of Common Cathode LED
Choosing Common Cathode LED displays can transform both creative and operational outcomes with:
Up to 40% energy savings over the display’s lifetime
Lower carbon emissions through reduced HVAC and transport needs for virtual production shoots
Longer product lifecycle, minimizing electronic waste
