Ultra Bright White 0.32-Inch (8.2mm) 7-Segment LED Display Common Anode for Refrigerator & Home Appliance Controls

0.32-Inch (8.2mm) 7-Segment LED Display, Ultra Bright White, Common Anode for Refrigerator & Home Appliance Controls

Product Overview

This compact 7-segment LED display is engineered for clear, energy-efficient numeric readouts in home electronic appliances—featuring a 0.32-inch (8.2mm) digit height and space-saving outer dimensions (33.6×18.5×9mm). Configured as common anode for seamless integration into standard appliance circuits, it delivers vivid ultra bright white emission through a specialized yellow diffused epoxy + black surface with protective film design. The yellow diffused layer ensures uniform light distribution across segments, while the black surface minimizes glare and the film safeguards against scratches during assembly. Optimized for efficiency  and durability, it supports 6 additional emission colors and multi-color customization—making it a versatile solution for refrigerators, cooling/heating controls, and instrument panels.

Key Specifications

Core Product Features

1. Optimized Visibility for Appliance Controls

Yellow diffused epoxy: Eliminates "hotspots" across segments, ensuring every digit (0-9) glows uniformly—critical for reading precise values like refrigerator temperature, heating control settings, or digital indicator metrics.

Black surface anti-glare design: Reduces reflection from kitchen lights or sunlight, keeping digits sharp even when viewed from off-center angles.

Ultra bright white emission: Strikes a balance between visibility and comfort—bright enough to stand out in dim appliance interiors without being harsh on the eyes.

2. Energy Efficiency for 24/7 Operation

Extremely low current (5-10mA/LED): Minimizes energy draw, making it ideal for appliances that run nonstop. Aligns with eco-friendly appliance standards and reduces long-term electricity costs for users.

2.8-3.2V/LED forward voltage: Compatible with standard power supplies in home electronics, eliminating the need for custom voltage regulators and simplifying circuit design for manufacturers.

3. Durable & Easy to Integrate

Stable performance & long lifespan: Built with high-quality LED chips and durable epoxy to resist temperature fluctuations and daily wear—ensuring consistent functionality for years.

Continuous uniform segments: Maintains brightness consistency over time, avoiding the "fading segments" issue common in low-quality displays—essential for appliances with long service cycles.

Hassle-free mounting: Designed for direct installation on PCBs and compatibility with standard sockets, with a compact 33.6×18.5×9mm profile that fits into slim appliance control panels.

4. Versatility & Compliance

Multi-color & OEM/ODM flexibility: Beyond ultra bright white, 6 additional colors let brands match appliance aesthetics—e.g., red for "error" alerts, green for "normal status", or amber for warm, ambient displays. OEM/ODM support enables customizations for digit size, package dimensions, or brightness, tailored to specific appliance designs.

RoHS Directive-compliant: Free from restricted substances , ensuring compliance with global regulations for home electronics—no barriers to exporting to key markets like the EU, North America, or Asia.

Applications

Tailored for home electronic appliances requiring compact, reliable numeric displays:

Refrigerator Controllers/Indicators: Showing internal temperature, door-open alerts, or ice-making mode status.

Cooling/Heating Controls: Displaying thermostat settings, fan speed levels, or timer durations

Instrument Panels: Industrial gauges or small home appliance displays

Digital Indicators: Battery chargers, smart sockets, or food thermometers
