Custom LED Numeric Display for Amplifiers (Voltage & Current)
Amplifier Voltage & Current LED Digital Display - Hongcheng Optoelectronics LED Manufacturer
This LED digital display is designed for amplifiers and power supply equipment, simultaneously showing output voltage, current, battery percentage, and other parameters. Its high-brightness yellow-green readout stays clear and easy to read even under strong light. Built with Grade A chips and LED SMD lamps, it resists high/low temperature cycling, is highly anti-static, and offers a long service life — customized for mid-to-high-end customers.
1. Through-hole (pin) type
2. SMD type
3. Phosphor-film excitation type
and other manufacturing processes are available, customized to the needs of mid-to-high-end customers. Drawings and samples are welcome, and we can produce a 3D sample so you can preview the result before mass production.
