Product Applications
This LED numeric display is designed specifically for amplifiers and power supply equipment, showing output voltage, current, charge percentage and other parameters simultaneously. Its bright yellow-green display remains clear and readable under strong light.
Q: How should I choose between common-cathode and common-anode LED displays?
A: It depends on the driver circuit. Shift-register/constant-current drivers mostly use common cathode, while direct transistor drive mostly uses common anode. If unsure, send the circuit diagram to our engineering team for confirmation.
