High-Definition Display: Equipped with 96 pcs high-precision LED lamp beads, supporting 8-bit grayscale adjustment, which can display subtle color changes and data details, and the refresh rate is up to 120Hz to avoid screen flicker.
Customizable Display Modes: It supports single-color fixed, full-color gradient, breathing, chasing and other display modes, and the display parameters can be adjusted through the control system to meet the personalized needs of different industries.
Strong Anti-Interference Ability: The signal line adopts shielded wire design, which can effectively resist electromagnetic interference in industrial environments, and the display effect is not affected by nearby high-power equipment.
Easy Installation & Maintenance: The snap-in installation structure is adopted, which can be fixed without tools; the modular design makes the damaged part easy to replace, reducing the maintenance difficulty.

Q1: What is the difference between DY-3815 and ordinary LED digital tubes?
A1: Compared with ordinary single-color LED digital tubes, DY-3815 supports full-color display, with richer color expression and stronger scene adaptability. At the same time, it has higher brightness, better anti-interference performance and longer service life, and is more suitable for professional equipment in industrial, medical and other fields.
Q2: Can the DY-3815 be customized according to specific needs?
A2: Yes, we provide personalized customization services, including adjusting the size of the digital tube, changing the brightness range, customizing the wire length and interface type, and even developing exclusive display modes according to the special needs of the industry. The minimum order quantity for customized products is 500 pieces.
Q3: Which control systems is this product compatible with?
A3: It supports mainstream control systems such as SPI and I2C. It can be perfectly matched with microcontrollers such as STM32, Arduino, Raspberry Pi, and industrial control equipment such as PLC. We will provide detailed technical manuals and sample codes to help engineers complete the integration quickly.
Q4: Is the DY-3815 suitable for outdoor long-term use?
A4: The product has IP65 waterproof and dustproof level, and is equipped with anti-UV coating, which can resist the erosion of sunlight and rain. It is suitable for outdoor scenarios such as outdoor monitoring equipment and vehicle external displays. For extremely harsh environments, we can provide enhanced waterproof customization (up to IP67).
Q5: How to solve the problem of inconsistent display colors?
A5: The color inconsistency is usually caused by the inconsistency of the control signal voltage or the deviation of the LED lamp beads. First, ensure that the input voltage is stable (DC 5V/12V ±5%); second, you can use the supporting software to calibrate the color of each lamp bead; if the problem persists, please contact our after-sales team for replacement.
Q6: What is the lead time for bulk orders?
A6: For standard models, the lead time is 5-8 working days for orders of less than 10,000 pieces; for orders of more than 10,000 pieces, the lead time is 10-15 working days. For customized products, the lead time will be extended by 3-5 working days according to the complexity of customization, and we support batch delivery to meet your production schedule.
