COB/COG Dot Matrix Displays - Durable & Low Power for Microwave/Appliance Controls & Home Electronics

Engineered for modern household appliances, our monochrome dot matrix LCDs with COB (Chip-on-Board) or COG (Chip-on-Glass) technology deliver crisp readability and robust performance in kitchens and living spaces. Ideal for microwave ovens, rice cookers, air fryers, and other appliances, these displays combine rugged construction, low power consumption, and user-friendly interfaces to enhance daily convenience.

Key Features & Specifications

1. Appliance-Optimized Durability

• Heat & Moisture Resistance: Operates at 0°C~70°C (storage: -30°C~85°C), withstanding steam, grease, and frequent cleaning.

• Anti-Scratch Surface: Tempered glass protects against scratches from utensils or abrasive cloths.

• COB/COG Options:

  • COB: Enhanced shock resistance for high-vibration environments (e.g., blenders).

  • COG: Ultra-thin (≤1.5mm) for sleek, space-saving appliance panels.

2. Clear & Customizable Display

• Dot Matrix Flexibility: 128x64 to 192x64 resolutions support icons (), progress bars, and multilingual text.

• High Contrast (≥600:1): Sharp visibility under bright kitchen lighting or dim settings.

• Backlight Options: White/Amber LED (100-300 cd/m²) with PWM dimming for eye comfort.

• 3. Energy Efficiency & Integration

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

• Wide Voltage Compatibility: 3.0V~5.5V DC (supports USB or direct appliance power).

• Plug-and-Play Interfaces: SPI, I²C, or 8-bit parallel mode for quick PCB integration.
