Industrial COB/COG Dot Matrix Displays - High Contrast & Wide Temp for PLC/Control Panels & Industrial Automation

Designed for industrial automation and machinery, our monochrome dot matrix LCDs with COB (Chip-on-Board) or COG (Chip-on-Glass) technology deliver unmatched durability and clarity in harsh environments. Tailored for CNC machine control panels, inverter parameter screens, and PLC interfaces, these displays combine high contrast, low power consumption, and robust construction to ensure reliable operation in demanding industrial settings.

Key Features & Specifications

1. Industrial-Grade Durability

• COB/COG Encapsulation: Dustproof, shock-resistant, and moisture-proof (IP65 optional), ideal for CNC workshops and high-vibration environments.

• Wide Temperature Range: Operates at -30°C~80°C (storage: -40°C~85°C), tested for foundries, cold storage, and high-heat industrial zones.

• Long Lifespan: 50,000-hour LED backlight with ≤3μA standby current, ensuring minimal maintenance and energy efficiency.

2. Precision Display Performance

• High Contrast (≥800:1): Optimized for readability under strong ambient light or dim conditions, with 160° viewing angles for multi-operator visibility.

• Dot Matrix Flexibility: Customizable 128x64 to 240x128 resolutions, supporting alphanumeric characters, symbols, and simple graphics (e.g., CNC toolpaths, parameter grids).

• Fast Response (≤15ms): Real-time updates for dynamic data like RPM, torque, or voltage levels.

3. Seamless Integration

• Wide Voltage Compatibility: 3.3V~5.5V DC input, compatible with industrial 12V/24V power systems.

• Multi-Protocol Interfaces: RS-232, SPI, or I²C for direct PLC/controller integration.

• Ultra-Thin Design: ≤2.0mm thickness (COG) or ≤3.5mm (COB), suitable for space-constrained panels.
