4-Digit 0.56-Inch (14.2mm) 7-Segment LED Display – Pure Green, Common Anode for Instrument Panels & Home Appliances

Product Description

Product Overview

This 4-digit 7-segment LED display is engineered for clear, reliable numeric readouts in instrument panels, home appliances, and digital indicators—featuring a 0.56-inch (14.2mm) character height, compact outer dimensions (50.3×19.0×8mm), and vivid pure green emission. Configured as common anode for seamless integration into standard circuits, it stands out with a high-contrast design: white segments on a black surface that eliminates glare and ensures sharp visibility, even in bright ambient light. With a luminous intensity of 120-140mcd, it delivers bright, consistent illumination while maintaining energy efficiency (2.8-3.2V/LED forward voltage, 5-10mA/LED forward current). Built for durability (stable performance, long lifespan) and ease of use (IC compatibility, easy assembly), it supports 6 additional emission colors (red, blue, yellow green, amber, orange, pure white) and meets RoHS compliance—making it a versatile solution for temperature/humidity indicators, set-top boxes, and home appliance controls.

Core Product Features

1. High Contrast & Vivid Pure Green Emission

White segments + black surface: The bold contrast eliminates reflection from overhead lights or sunlight, ensuring digits (0-9) remain—critical for reading precise values like temperature, humidity, or set-top box channel numbers .

Pure green emission (120-140mcd): The vibrant, cool-toned green is easy on the eyes for prolonged viewing (ideal for instrument panels monitored by technicians) while standing out in dim environments (e.g., home appliance control panels in low-light kitchens).

2. Energy Efficiency & Durable Performance

Extremely low current (5-10mA/LED): Minimizes energy draw, making it suitable for 24/7 operated devices (e.g., always-on temperature/humidity indicators, set-top boxes in standby mode). Aligns with eco-friendly standards for home appliances and electronics.

Stable performance & long lifespan: Built with high-quality LED chips and durable encapsulation to resist voltage fluctuations and environmental wear (e.g., humidity in kitchens, vibration in industrial instrument panels). Ensures consistent brightness for 50,000+ hours, reducing maintenance needs.

3. Easy Integration & Versatility

Common Anode polarity: Matches standard circuit designs for instrument panels, home appliances, and digital indicators—eliminating the need for custom voltage inversion or adapter circuits. Simplifies PCB design and speeds up manufacturing for brands.

IC compatible: Works seamlessly with common display driver ICs, enabling plug-and-play integration into existing control systems (no redesign required for set-top boxes or temperature indicators).

Easy-to-assemble: Compact 50.3×19.0×8mm dimensions and standardized pin layout support direct mounting on PCBs or sockets—even for space-constrained setups like slim home appliance control panels or dense instrument panels.

4. Regulatory Compliance & Color Flexibility

RoHS Compliant: Free from restricted substances , ensuring compliance with global regulations for consumer electronics, home appliances, and industrial equipment. No barriers to exporting to key markets like the EU, North America, or Asia.

Multi-color options: Beyond pure green, 6 additional colors cater to diverse design needs:

Red: Ideal for "alert" statuses.

Blue: Suited for modern, sleek home appliances.

Yellow green/amber/orange: Perfect for warm, ambient displays.

Applications

Tailored for numeric readout scenarios across consumer and industrial use cases:

Instrument Panels: Industrial gauges (pressure, flow rate), automotive auxiliary displays (battery voltage, oil level), and medical equipment (simple numeric metrics).

Home Appliances: Refrigerator temperature controls, microwave timers, electric ovens, and induction cookers (power settings).

Digital Indicators: Temperature/humidity monitors, battery chargers, and digital scales (weight readings).

Set-Top Boxes: Channel numbers, signal strength, and playback time.
