0.39" Single-Digit 7-Segment Common Anode White LED Display for Hair Dryers

Product Overview

Introducing the 0.39" Single-Digit 7-Segment Common Anode White LED Display—a compact, high-visibility numeric solution engineered for hair dryers and small consumer electronics. Designed to fit seamlessly into hair dryer control panels (where space is at a premium), this display features a 0.39" (9.9mm) character height for clear readability, ultra bright white illumination (100-140mcd/dice), and a common anode configuration for easy integration with hair dryer circuit boards.

With a slim 10×13×7mm package, black/grey face for anti-glare contrast, and RoHS compliance, it balances functionality and durability—critical for hair dryers (which operate in warm, humid bathroom environments). The display's big viewing angle ensures users can easily read heat settings (e.g., "1," "2," "3") from multiple positions, while low power consumption and long lifetime align with consumer appliance efficiency standards. Multiple emitting color options and support for OEM/ODM orders further extend its versatility for diverse product designs.

Key Features

1. Hair Dryer-Optimized Design

Compact 10×13×7mm Package: Fits into slim hair dryer control panels without adding bulk, avoiding interference with grip or button layouts—essential for ergonomic consumer appliances.

0.39" (9.9mm) Character Height: Balances readability (for heat speed settings) and space efficiency; digits are large enough to be seen quickly (even with wet hands) but small enough for compact hair dryer designs.

Black/Grey Face: Reduces glare from bathroom lighting or sunlight, ensuring the white LED illumination stands out clearly—preventing misreads of heat settings (a key safety feature for hair dryers).

2. Superior Visibility & Reliability

Ultra Bright White Illumination: 100-140mcd/dice luminous intensity and 0.29-0.33 (X/Y) chromaticity deliver crisp, pure white light that cuts through bathroom humidity and ambient light, ensuring settings are visible at a glance.

Big Viewing Angle: Wide horizontal and vertical visibility means users can read the display without tilting the hair dryer—enhancing usability and safety during styling.

Stable Performance in Warm Environments: Engineered to withstand the mild heat generated by hair dryers (typical operating temperatures up to 40°C), maintaining consistent brightness and avoiding display lag or failure.

3. Easy Integration & Durability

Common Anode Configuration: Simplifies wiring with hair dryer control boards and standard driver ICs (e.g., for heat speed selection), reducing circuit design complexity for appliance manufacturers.

Easy Assembly: Designed for hassle-free PCB mounting, compatible with automated production lines for high-volume hair dryer manufacturing—no specialized tools required.

Long Lifetime: High-quality LED chips ensure a typical lifespan of 50,000+ hours, matching the 3-5 year service life of most hair dryers and minimizing replacement needs for end-users.

4. Flexibility & Compliance

Multi-Color Options: Beyond white, choose from red, blue, yellow green, pure green, amber, orange, or yellow to match hair dryer brand aesthetics or functional needs (e.g., red for high heat, green for low heat).

OEM/ODM Support: Accepts customizations (e.g., modified face color, adjusted brightness, tailored pin layouts) to align with specific hair dryer design requirements.

RoHS Directive-Compliant: Meets international environmental and safety standards, ensuring compatibility with global hair dryer markets (Europe, North America, Asia, etc.).
