Product Introduction

The DY-4615-1 LED digital tube is a high-reliability numeric display component designed to meet the rigorous demands of professional industries. As a flagship model from our factory—specialized in LED digital tubes, LED color screens, and LED single/double color strips—this product integrates mature semiconductor technology with industry-specific design optimizations to deliver consistent performance in critical scenarios.

Crafted with high-luminance Taiwan Epistar LED chips and flame-retardant ABS housing, the DY-4615-1 features a classic 7-segment structure that supports clear numeric display (0-9) and partial alphabetic indication (A-F). Operating at DC 5V/12V with optimized current management, it achieves a perfect balance between bright visibility and energy efficiency, making it a preferred choice for biometrics, medical electronics, smart homes, automotive electronics, industrial automation, and office automation sectors.

Unlike ordinary LED digital tubes, the DY-4615-1 undergoes strict aging tests and environmental adaptability verification, ensuring stable operation in harsh conditions such as temperature fluctuations, electromagnetic interference, and mechanical vibration. Whether used for data visualization, status feedback, or operational prompts, it provides accurate and intuitive display effects that enhance the reliability of end-equipment.

Product Advantages

Exceptional Visual Clarity: Boasts a contrast ratio of 1200:1 and brightness up to 650 cd/m², ensuring clear visibility even in strong ambient light (such as factory workshops or outdoor kiosks). The wide viewing angle of 160° horizontal and 140° vertical eliminates blind spots for multi-directional observation.

Industrial-Grade Durability: Withstands a working temperature range of -30℃ to +70℃, adapting to extreme environments from cold storage to high-temperature workshops. The product has a service life exceeding 60,000 hours, reducing maintenance frequency and replacement costs for equipment manufacturers.

Energy-Saving & Stable Performance: Adopts low-voltage constant-current drive technology, consuming only 0.3W per unit—40% lower than traditional LED digital tubes. The built-in overcurrent and overvoltage protection circuits prevent damage caused by power fluctuations, ensuring continuous operation.

Strong Compatibility: Supports direct connection with common control chips such as 51 MCU, Arduino, and PLC, without the need for additional driving modules. Compatible with both common cathode and common anode circuits, adapting to different circuit design requirements.

Strict Quality Assurance: Passes international certifications including RoHS, CE, and FCC. Each unit undergoes 72-hour high-temperature aging, vibration, and moisture resistance tests. Backed by a 3-year warranty, providing reliable after-sales support for critical applications.

Product Features

High-Definition Numeric Display: 7-segment design with 1.2-inch digit height, supporting clear display of numbers 0-9 and letters A-F, suitable for data reading at distances up to 5 meters.

Multiple Color Options: Available in red, green, blue, and yellow, with uniform luminous intensity (error ≤5%) ensuring consistent display effects in multi-tube combinations.

Compact & Easy Installation: Standard pin and solder pad interfaces, with a slim thickness of only 8mm, fitting into narrow installation spaces of precision equipment. Comes with installation guides for quick integration.

Fast Response Speed: The response time is less than 100ns, supporting real-time dynamic display of data such as counting, timing, and measurement values without lag.

Anti-Interference Design: The external shielded circuit reduces electromagnetic radiation interference, making it suitable for industrial environments with complex electrical signals.

Environmentally Friendly Material: Uses lead-free and mercury-free materials, complying with international environmental standards, suitable for export-oriented equipment production.

Product FAQ

Q1: What is the difference between common cathode and common anode versions of the DY-4615-1?

A1: The core difference lies in the circuit connection mode. The common cathode version connects the LED cathode to the ground, controlled by positive voltage input; the common anode version connects the LED anode to the positive power supply, controlled by ground signal. Both versions are available, and you can choose based on your circuit design. We provide wiring diagrams for both types to facilitate integration.

Q2: Can the DY-4615-1 be customized for specific digit heights or colors?

A2: Yes, we offer customization services. Digit heights can be adjusted from 0.8 inches to 2 inches, and special colors such as orange and white are available. We can also customize the pin length and interface type according to your equipment installation requirements, with a minimum order quantity of 500 units for customized models.

Q3: Is the product suitable for outdoor use?

A3: The standard model has an IP44 protection rating, suitable for semi-outdoor environments such as awnings and covered kiosks. For fully outdoor applications, we provide an enhanced IP65 waterproof version with anti-UV coating to prevent fading and performance degradation caused by sunlight exposure.

Q4: How to solve the problem of dim display or uneven brightness?

A4: First, check if the power supply voltage is within the 5V/12V range (fluctuation ≤±0.5V). Second, ensure the current-limiting resistor in the circuit matches the product specifications (we recommend a 220Ω resistor for 5V systems). If the issue persists, contact our technical team for free debugging support.

Q5: What is the lead time for bulk orders?

A5: For standard models (red, 1.2-inch, common cathode), the lead time is 5-7 working days for orders under 10,000 units. For customized models or large orders (over 50,000 units), the lead time is 12-15 working days. We support batch delivery to align with your production schedule.

Q6: Does the product come with technical documentation?

A6: Yes, each order includes a detailed datasheet covering electrical parameters, wiring diagrams, installation dimensions, and compatibility information. We also provide CAD drawings and sample code for MCU control upon request, helping your R&D team complete integration quickly.
