Long Lead Pin Ultra Bright White 10mm (0.39-Inch) 3-Digit 7-Segment Common Anode LED Display for Washing Machines

Product Overview

Introducing the Long Lead Pin Ultra Bright White 3-Digit 7-Segment Common Anode LED Display—a washing machine-optimized solution engineered for cycle timers, home appliances, and digital indicators. Designed to prioritize easy assembly (via long lead pins), clear time readouts, and durability in damp laundry environments, this 3-digit display excels at showing washing machine metrics: cycle duration (e.g., "04:00" for 40 minutes), remaining time (e.g., "00:59"), or cycle stages (e.g., "02" for rinse).

Its 10mm (0.39-inch) character height ensures readability from 1–2 meters (typical distance for laundry room checks), while the 30.02×12.8×7mm form factor fits into slim washing machine control panels. The yellow segments on a white surface create soft, eye-friendly contrast with ultra bright white light (80-100mcd), avoiding glare in bright laundry rooms and resisting washout in dim spaces.

With long lead pins (for secure PCB mounting), common anode polarity, and RoHS compliance, this display simplifies assembly for washing machine manufacturers, withstands laundry room humidity, and delivers reliable 24/7 performance for home appliance use.

Key Features (Washing Machine-Optimized)

1. Long Lead Pins for Easy, Secure Assembly

Extended Lead Pins: Longer pins than standard displays enable easier insertion into washing machine control board PCBs—simplifies manual or semi-automated assembly, reduces misalignment errors, and ensures a tight connection (critical for vibration-prone washing machine operation, e.g., spin cycles).

Flexible Mounting: The long pins accommodate slight variations in PCB hole spacing (common in mass-produced washing machines), eliminating the need for precise hole alignment and lowering production scrap rates.

Durable Pin Construction: Pins resist corrosion from laundry room humidity, preventing loose connections or display failure over time—matches the 8–10 year service life of most washing machines.

2. Superior Visibility for Laundry Room Use

Ultra Bright White Illumination (80-100mcd): High luminous intensity (X/Y: 0.29-0.33/0.29-0.31, neutral white) cuts through laundry room glare (e.g., overhead lights, natural sunlight) and remains visible through minor steam or dust—users can quickly check "01:15" remaining time without leaning in.

Yellow Segments on White Surface: Unlike traditional black surfaces, the white backdrop softens harsh light (reducing eye strain during evening laundry runs) while yellow segments ensure digits (0-9) and colons (for time) stay distinct—avoids misreading "06:00" as "09:00" (a mistake that could lead to over-washing).

Big Viewing Angle: Uniform light distribution ensures readability from off-center positions (e.g., viewing the washer while folding clothes nearby)—ideal for busy laundry room workflows.

3. Stable Performance & Energy Efficiency

Humidity-Resistant Design: Withstands mild moisture in laundry rooms (e.g., steam from hot washes, damp air) without segment dimming or pin corrosion—maintains stable performance even in high-humidity environments.

Low Power Consumption (5-10mA/LED): Extremely low current draw minimizes washing machine energy use (critical for eco-friendly models) and reduces strain on the appliance's power system, extending overall lifespan.

Continuous Uniform Segments: No "hot spots" or dim edges across segments (laboratory-tested <2% brightness variation)—guarantees consistent readability of time details (e.g., the bottom bar of "6", the middle bar of "8") for accurate cycle tracking.

4. Versatility & Compliance

Multi-Color Options: Beyond ultra bright white, available in red (for alerts, e.g., "ERR" for errors), blue (modern aesthetics), green (eco-cycle cues), yellow green, amber, and orange—flexible for functional prompts (e.g., red = "cycle pause", green = "cycle complete").

Common Anode Polarity: Works with standard washing machine driver ICs (e.g., TM1637, HT1621)—simplifies circuit design for manufacturers and integrates seamlessly with washer firmware (e.g., cycle time counting, stage updates).

RoHS Compliant: Free from lead, mercury, and harmful substances—safe for home use (even near laundry detergents) and export to global markets (EU, North America, Asia), meeting washing machine safety standards.

Technical Specifications

Applications

While optimized for washing machines, this display also excels in:

Home Appliances: Air conditioner controllers (temp "26°C", timer "01:00"), microwave ovens (cook time "02:30"), or electric dryers (drying time "01:45").

Temperature Controllers: Room thermostats (temp "22°C"), mini fridge monitors (temp "5°C"), or greenhouse regulators (temp "25°C").

Instrument Panels: Small industrial testers (voltage "120V"), battery chargers (charge "90%"), or fitness equipment (workout time "15:00").
