COB/COG Dot Matrix Wearable Displays - High Contrast & Low Power for Smartwatch/Fitness Tracker Panels

Designed for next-generation smart wearables, our monochrome dot matrix LCDs with COB (Chip-on-Board) or COG (Chip-on-Glass) technology deliver crisp, energy-efficient displays for fitness trackers, smartwatches, and health monitors. These screens combine ultra-thin profiles, high contrast, and dynamic graphics support to visualize heart rate curves, step counts, and workout metrics with precision.

Key Features & Specifications

1. Wearable-Optimized Design

• Ultra-Thin & Lightweight: ≤1.0mm thickness (COG) and <5g weight for seamless integration into wristbands or clip-on devices.

• Battery Efficiency: ≤1.5μA standby current (7+ days on a 100mAh battery for continuous heart rate monitoring).

• High Contrast (≥800:1): VA-enhanced visibility under sunlight or indoor lighting.

2. Dynamic Display Performance

• Dot Matrix Flexibility: 128x128 to 240x240 resolutions support graphs , icons , and multilingual text.

• Fast Refresh Rate (≤10ms): Smooth updates for real-time fitness data and animations.

• Touch Integration: Glove-compatible capacitive touch or gesture-sensitive overlays.

• 3. Durability & Comfort

• IP68 Waterproofing: Resists sweat, rain, and submersion up to 1.5m for 30 minutes.

• Anti-Scratch Surface: Chemically strengthened glass (9H hardness) protects against daily wear.

• Wide Temperature Range: Operates at -10°C~60°C, ensuring reliability during outdoor workouts.
