• Module Dimensions: 62.0mm x 24.0mm x 2.17mm (2.4" x 0.9" x 0.09")
• Built-in Controller: Sino Wealth SH1106 (or equivalent)
• Multiple Interface Options: 6800, 8080, 4-Wire SPI, I²C
• Supply Voltage: +3V logic (VDD), 12V display (VPP)
• Exceptional Contrast Ratio: 10,000:1
• Ultra-Fast Response Time: 10µs
• Wide Viewing Angle: 160° both horizontal and vertical
• Brightness: 100-150 cd/m² (typical)
• Operating Temperature Range: -40°C to +80°C
• Long Operating Lifetime: 50,000 hours (typical)

Display Characteristics

This OLED module features self-emissive pixel technology, eliminating the need for a backlight and providing superior contrast compared to traditional LCD displays. The yellow emission provides excellent readability and is particularly effective for status indicators, instrumentation, and industrial applications.

The display offers:

• True Black Pixels: Exceptional contrast with completely dark "off" pixels
• No Backlight Required: Lower power consumption and simpler design
• Polarized Design: 1/32 duty cycle for smooth, flicker-free operation
• Volatile Memory: Display data requires continuous power

This flexibility allows easy integration with a wide variety of microcontrollers and development platforms.

Applications

The CFAL12832N0-022Y is ideal for:

• Industrial instrumentation and control panels
• Medical device status displays
• Consumer electronics
• Automotive dashboard indicators
• Test and measurement equipment
• Portable devices
• Status and notification displays
• IoT and embedded systems

Arduino Compatible! Check out the demo sketch in the files section.

Design Considerations

Power Management: The VPP voltage can be adjusted to control display brightness. Lower VPP values reduce brightness and power consumption while extending OLED lifetime.
