COB/COG Dot Matrix Displays - High Contrast, Low Power for Printer/Fax/Scanner Panels & Office Automation

Designed for modern office environments, our monochrome dot matrix LCDs with COB (Chip-on-Board) or COG (Chip-on-Glass) technology deliver crisp readability and reliable performance in printers, fax machines, and multifunctional devices. Combining rugged construction, energy efficiency, and customizable interfaces, these displays ensure clear status monitoring and user interaction in high-volume office settings.

Key Features & Specifications

1. Office-Optimized Durability

• COB/COG Encapsulation: Dust-resistant and anti-static design, ideal for paper-heavy environments (printers/copiers).

• Wide Temperature Range: Operates at 0°C~60°C, ensuring stability in air-conditioned offices or server rooms.

• Anti-Scratch Surface: Tempered glass protects against accidental abrasions during maintenance.

2. High-Readability Display

• Dot Matrix Flexibility: 128x64 to 192x64 resolutions support alphanumeric characters, icons , and progress bars.

• High Contrast (≥600:1): Clear visibility under office lighting or low-light conditions.

• Backlight Options: White LED (150 cd/m²) for standard use or amber LED for reduced eye strain.

• 3. Energy & Integration Efficiency

• Ultra-Low Power: ≤2μA standby current (5+ years on coin cells for wireless devices).

• Plug-and-Play Interfaces: SPI, I²C, or parallel 8-bit mode for quick integration with office device controllers.

• Ultra-Thin Design: ≤2.5mm thickness (COG) fits compact printer panels or portable scanners.
