Ti Common Cathode Series Products

Pioneer Vision, Innovate Display

A common cathode LED screen is an energy-saving display design where the negative terminals (cathodes) of the red, green, and blue (RGB) LED chips are linked together into a shared ground, while each color’s positive terminal (anode) is powered separately.

Key features

Four-Level Energy Saving Technology

Level I: Dynamic Energy Saving: When there is no signal display, the constant current transistor chip's driving circuit is shut down;

Level II: Black Screen Energy Saving: When the display screen is completely black, the chip's static current consumption drops from 6mA to 0.6mA;

Level III: Full Screen Energy Saving: When the low level is maintained for 300ms, the chip's static current consumption drops from 6mA to 0.5mA;

Level IV: Branch Power Supply Voltage Reduction Energy Saving: The current first passes through the LED bead and then to the IC's negative terminal, resulting in a smaller forward voltage drop and a smaller conduction resistance.

How It Works

Independent Power: Red, green, and blue diodes require different operating voltages to shine.

Precise Control: A common cathode setup lets the driver integrated circuit (IC) send the exact, lower voltage needed for each specific color rather than a single high-voltage supply.

Current Path: Current flows from the driver IC, through each LED's anode, into the shared cathode, and down to the ground.

Key Benefits

Lower Energy Use: Precise voltage matching cuts power consumption by up to around 30% compared to older designs.

Less Heat: Running at exact voltages reduces wasted energy and keeps the screen much cooler, extending the overall lifespan of the display.

Better Color Accuracy: Independent pixel and color control prevents tint distortion and delivers uniform brightness.

Multiple heat dissipation designs

The dual-layer power supply, combined with a unique heat dissipation design and the excellent thermal conductivity of the aluminum module itself, results in better overall screen heat dissipation, eliminating the need for air conditioning, ensuring high reliability and a long service life.

Cabinet Dimension

Cabinet Weight

All-aluminum enclosure structure: Die-cast aluminum modules and profiled aluminum enclosure provide better flatness. The lightweight enclosure structure reduces weight by 35% per square meter compared to traditional iron enclosures, saving on transportation costs.

Modular design of modules, housing and power supply box, front and rear maintenance; hard connection and supports wall mounting, greatly save structural costs.
