Ultra Bright Red 10mm 4-Digit 7-Segment LED Clock Display (Common Cathode)

Product Overview

Introducing our Ultra Bright Red 4-Digit 7-Segment LED Clock Display—a specialized digital visualization component engineered for precision, clarity, and seamless integration into timekeeping and counting devices. Designed with a focus on readability and energy efficiency, this display is the ideal choice for digital timers, clocks, and status indicators that demand reliable numerical output.

Featuring a compact form factor (outer dimensions: 40.18 × 12.8 × 7mm) and a 0.39-inch (10.0mm) character height, it strikes the perfect balance between space-saving design and visible performance—making it suitable for both compact devices (like set-top boxes) and larger panels (such as instrument dashboards). Its classic "white segments on black surface" design creates strong contrast, ensuring numbers remain sharp and legible even in low-light or bright ambient environments. With ultra bright red as the primary emission color (and 7 additional color options available), paired with common cathode polarity, it adapts effortlessly to diverse electronic project needs.

Why Choose This 4-Digit 7-Segment LED Display?

When selecting a display for timekeeping, counting, or status indication, performance, durability, and ease of use are critical. Our 4-digit 7-segment display excels in all areas—here's why it stands out:

1. Exceptional Visibility for Time & Count Readouts

Ultra Bright Red Emission: With a wavelength of 620-625nm and luminous intensity of 70-85mcd, the display delivers vivid, eye-catching red light that cuts through glare or dimness. Whether used in a sunlit kitchen (for a temperature indicator) or a dim living room (for a set-top box), numbers stay clear at a glance.

Contrast-Enhanced Design: White segments on a black surface maximize readability—no more squinting to distinguish between digits (e.g., "8" vs. "0") in fast-paced or low-light scenarios.

2. Energy Efficiency That Extends Device Life

Engineered for minimal power draw, this display offers:

Low Power Consumption & Extremely Low Current: Operates at a recommended forward current of 5-10mA per LED and a forward voltage of 1.8-2.2V per segment—ideal for battery-powered devices (like portable timers) or 24/7-running appliances (like refrigerators), reducing energy costs and extending battery lifespan.

Reverse Voltage Protection: A 5V reverse voltage rating prevents damage from accidental polarity reversal, adding a layer of durability to your circuit.

3. Industrial-Grade Reliability & Longevity

Built to withstand continuous use, the display boasts:

Stable Performance: Maintains consistent brightness and functionality across varying temperatures and voltage fluctuations—critical for instrument panels or industrial indicators that demand precision.

Long Lifespan: High-quality LED chips minimize light decay over time, eliminating the need for frequent replacements (saving maintenance costs for manufacturers and users alike).

RoHS Compliance: Free from hazardous substances (e.g., lead, mercury), meeting global environmental standards and ensuring safety for consumer and industrial applications.

4. Hassle-Free Integration for Every Project

Whether you're designing a consumer appliance or an industrial control panel, this display simplifies assembly and circuit design:

Common Cathode Polarity: Easy to pair with standard LED driver ICs (e.g., 74HC595, TM1637), streamlining circuit layout and reducing development time.

Industrial Standard Size: Compact outer dimensions (40.18 × 12.8 × 7mm) fit seamlessly into existing PCB designs—no custom enclosures or modifications required.

Easy Assembly: Clear pin labeling and a slim profile make installation quick, even for beginner engineers or DIY enthusiasts.

5. Versatility to Match Diverse Needs

While optimized for clocks and timers, the display's flexibility extends to multiple applications:

Available in 7 emitting colors (red, blue, yellow green, pure green, pure white, amber, orange) to match your device's design aesthetic.

Suitable for set-top boxes, home appliances, temperature indicators, and instrument panels—one component, multiple use cases.
