Custom 7-Segment LED Numeric Display for Speakers (Clock/Time Display)
Speaker Clock LED Digital Tube Display - Hongcheng Optoelectronics LED Manufacturer
This LED digital tube display is suitable for card-insertion speakers, Bluetooth speakers, and other devices with clock and playback functions, showing time, playback status, USB/SD card mode, and other information. The high-brightness yellow digits stay soft and glare-free at night. 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.
