Ultra White Triple digit 7 segment led display common anode 0.56-inch for heating and cooling

Product Overview

Introducing the Ultra Bright White 0.56-Inch 3-Digit 7-Segment Common Anode LED Display—a high-performance numeric solution engineered for heating and cooling systems (AC controllers, temperature regulators) and home appliances. Designed to prioritize visibility, energy efficiency, and seamless integration, this display excels at delivering clear, reliable temperature readouts for critical climate control: setting AC cooling temps (e.g., "26°C"), adjusting heating targets (e.g., "22°C"), or monitoring room temperature (e.g., "20°C").

Its 14.2mm (0.56-inch) digit height ensures exceptional readability from 1–3 meters (typical distances for wall-mounted ACs or standing heaters), while the slim 37.6×19mm form factor fits neatly into standard climate controller panels—no bulky redesigns required. The yellow segments on a black surface create sharp contrast with ultra bright white light (100-120mcd), cutting through bright ambient light (e.g., sunlight through windows) or dim rooms (e.g., bedrooms at night) without eye strain.

With common anode polarity, low power consumption (5-10mA/LED), and RoHS compliance, this display balances durability, eco-friendliness, and performance—ideal for 24/7 operation in heating/cooling systems and home appliances.

Key Features (Heating & Cooling-Optimized)

1. Superior Visibility for Climate Control

Ultra Bright White Illumination (100-120mcd): High luminous intensity ensures temperature readouts stay clear in all lighting conditions—bright enough to resist washout from sunlight (e.g., living room ACs) and soft enough for nighttime use (e.g., bedroom heaters). The neutral white light (X/Y: 0.29-0.31) avoids color distortion, making digits (0-9) and decimal points (e.g., "23.5°C") easy to distinguish.

Yellow Segments on Black Surface: The yellow segment base enhances contrast with the black background, eliminating ambiguity in critical temperature settings (e.g., no mistaking "28°C" for "38°C" when adjusting AC). Unlike plain white segments, yellow undertones reduce eye fatigue during frequent adjustments (e.g., tweaking heating temps on cold mornings).

Big Viewing Angle: Wide viewing range (≥120° horizontal/vertical) ensures readability from off-center positions—perfect for shared spaces (e.g., a family room AC viewed from the couch or dining table) or tall heaters viewed from seated/standing heights.

2. Energy Efficiency for 24/7 Climate Control

Low Power Consumption (5-10mA/LED): Extremely low current draw minimizes energy use for heating/cooling controllers that run 24/7. For example, an AC controller using this display consumes ~0.05kWh per year—negligible compared to overall AC energy usage, while extending battery life for portable temperature regulators.

Optimized Forward Voltage (2.8-3.3V/LED): Compatible with standard 5V/12V power supplies used in AC and heating controllers—no need for custom voltage converters. Seamlessly integrates with existing controller circuits, reducing manufacturing complexity.

Extremely Low Standby Current: Even when not actively updating temperatures, the display draws minimal power—critical for energy-efficient home appliances (e.g., ENERGY STAR-certified ACs) and battery-powered portable heaters.

3. Reliable Performance & Easy Integration

Stable Performance in Temperature Fluctuations: Operates seamlessly in -10°C to 60°C (typical for heating/cooling environments)—from cold winter basements (heater use) to hot summer attics (AC use). Maintains consistent brightness and segment uniformity, no flickering during temperature updates (e.g., when AC cycles on/off).

Good Consistency: Laboratory-tested to ensure<3% brightness variation across segments and between units—critical for mass-produced climate controllers (e.g., 1000+ ACs) where display consistency reinforces brand trust.

IC Compatibility & Easy Assembly: Works with standard driver ICs (e.g., MAX7219, TM1638, HT1621) widely used in temperature controllers—simplifies circuit design. PCB direct-mounting supports automated production, reducing assembly time for high-volume heating/cooling devices.

4. Versatility & Compliance

Multi-Color Options: Beyond ultra bright white, available in 6 other high-performance colors to match functional needs or brand aesthetics:

Red: Alerts (e.g., "HIGH TEMP" for overheating heaters).

Yellow Green/Pure Green: Signals "energy-saving mode" (e.g., eco-friendly ACs).

Blue: Modern aesthetic for premium climate controllers.

Amber/Orange: Warm tone for heating systems (e.g., space heaters).

RoHS Compliant: Free from lead, mercury, and harmful substances—meets global environmental standards. Safe for use in family-friendly home appliances and export to markets like the EU, North America, and Asia.

Technical Specifications

Applications

This display is purpose-built for heating/cooling systems and climate-sensitive devices, including:

Air Conditioner Controllers: Wall-mounted ACs (showing set temp "26°C" and room temp "24°C"), portable ACs (cooling mode indicators), or smart ACs (energy-saving temp "28°C").

Temperature Controllers: Heating regulators (e.g., "22°C" for central heating), refrigerated display cases (e.g., "5°C" for food storage), or greenhouse climate controls (e.g., "25°C" for plant growth).

Home Appliances: Smart thermostats (e.g., "21°C" for bedrooms), heat pumps (defrost mode temp "5°C"), or electric fireplaces (heating temp "23°C").

Instrument Panels: Industrial climate control panels (e.g., factory cooling systems "18°C"), lab temperature monitors (e.g., "25°C" for sample storage), or automotive AC displays (e.g., "20°C" for cabin temp).

Why Choose This Display for Heating & Cooling?

Climate Control Precision: Big digit height + high contrast ensure accurate temperature reading—avoids costly mistakes (e.g., setting AC to "36°C" instead of "26°C").

All-Lighting Reliability: Ultra bright white light works in sunlight/dim rooms—no need to adjust controller placement for visibility.

Energy Efficiency: Low 5-10mA current cuts power use for 24/7 climate controllers, aligning with eco-friendly heating/cooling trends.

Easy Integration: Common anode polarity + standard size fit existing AC/heater PCBs—saves manufacturers redesign time.

Global Compliance: RoHS certification simplifies export to international markets, meeting consumer safety standards for home appliances.
