Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Numerical Data Display: Designed to show 3-digit numerical values (e.g., battery levels, step counts, temperature readings) using a high-contrast white-on-black 7-segment LCD, ensuring clarity in diverse lighting conditions.
  • Customizable Information: Supports text, icons, and percentage displays via integrated drive IC, enabling adaptation for specific applications like fitness metrics, IoT device interfaces, or industrial control panels.

Key features

  • 1. Material Technology: TN COG Construction for Durability and Compactness

  • With TN COG (Chip On Glass) construction, you can achieve a durable and compact design that saves up to 25% in space compared to modules with external drivers*. This technology ensures reliable performance in rugged environments while maintaining a sleek profile.

  • 2. Interactive Design: Integrated Drive IC and Customizable 7-Segment Display

  • With an integrated drive IC and customizable 7-segment digits, you can display numbers, text, and icons without needing external circuitry*, simplifying integration into devices like fitness trackers or smartwatches. The white-on-black contrast enhances readability in low-light conditions.

  • 3. Performance Parameters: Wide Temperature Range and LED Backlight

  • With a robust operating temperature range of -30°C to 70°C and energy-efficient LED backlight, you can ensure consistent performance in extreme environments while maintaining clear visibility in dark settings*. This outperforms standard modules with narrower temperature tolerances*.

  • 4. Scenario Solutions: Compact Design for Wearable and Space-Constrained Applications

  • With its small form factor and high-contrast display, you can seamlessly integrate it into compact devices like fitness trackers, smartwatches, or IoT gadgets*, delivering critical metrics (e.g., battery levels, step counts) in tight spaces.

  • 5. Certification Standards: RoHS Compliance for Eco-Friendly Use

  • With RoHS certification, you can ensure compliance with global environmental regulations, avoiding hazardous materials in production*. This sets it apart from non-certified alternatives in regulated industries.
