Round Custom LED Numeric Display for Audio Equipment
Round Audio LED Digital Display - Hongcheng Optoelectronics LED Manufacturer
This round LED digital display is suitable for the panels of audio equipment such as speakers, amplifiers, and players, showing volume, frequency, playback mode, and other information. Its round design matches the style of speaker panels. 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.
