Ultra White LED Display 7 Segment 4 Digit Common Cathode for Oven 58.2*19mm

Product Specification

Ultra Bright White 14.2mm (0.56-Inch) 4-Digit 7-Segment Common Cathode LED Display for Oven Timers      

Product Overview
Introducing the Ultra Bright White 4-Digit 7-Segment Common Cathode LED Display—a high-temperature-resistant solution engineered for oven timers, temperature controllers, and home appliances. Designed to prioritize heat tolerance, visibility, and reliability, this 4-digit display excels at showing oven-specific metrics: cook time (e.g., “04:00” for 4 hours), baking temperature (e.g., “180°C”), or countdown timers (e.g., “00:59” for 59 seconds).
Its 14.2mm (0.56-inch) digit height ensures readability from 1–2 meters (typical kitchen distance for oven viewing), while the 58.2×19×13.8mm form factor fits standard oven control panels—no bulky redesigns required. The yellow segments on a black face (with film) boost contrast with ultra bright white light, cutting through kitchen glare (e.g., overhead lights, sunlight) without eye strain.
With a wide working temperature range (+105°C ~ +120°C), common cathode polarity, and RoHS compliance, this display thrives in oven environments (where heat is constant) and delivers long-term performance for 24/7 use.

Key Features (Oven Timer & High-Temp-Optimized)
1. High-Temperature Resistance for Oven Use
Wide Working Temp Range (+105°C ~ +120°C): Specifically designed to withstand oven-side heat (e.g., radiant heat from oven chambers, warm control panel surfaces)—avoids brightness dimming, segment failure, or film warping that plagues standard displays in high-heat environments.
Fast Heat-Dissipation: Specialized material and pin design accelerate heat transfer away from LED chips, maintaining stable performance even when the oven runs at max temp (e.g., 250°C for baking).
Protective Film: The film on the black face shields segments from kitchen grease, food splatters, and heat-induced discoloration—easy to wipe clean and maintains clarity over years of oven use.
2. Superior Visibility for Kitchen Scenarios
Ultra Bright White Illumination: High luminous intensity ensures timer/temp readouts stay clear in bright kitchens (e.g., morning sunlight) or dim spaces (e.g., evening baking)—users can quickly check “01:15” remaining time without leaning in.
Yellow Segments on Black Face: The yellow segment base enhances contrast with the black background, eliminating “washout” and making digits (0-9) and symbols (e.g., colon for time “03:30”) sharp—avoids misreading “08:00” as “03:00” (a costly mistake for overbaked food).
Wide Viewing Angle: Uniform light distribution ensures readability from off-center positions (e.g., viewing the oven while stirring on the stovetop)—ideal for busy kitchen multitasking.
3. Energy Efficiency & Reliable Performance
Low Power Consumption (Extremely Low Current): Minimizes energy use for oven timers (which run during cooking) and extends battery life for portable temp indicators (e.g., handheld oven thermometers).
Stable Operation: Withstands temperature fluctuations (from room temp to +120°C) and minor vibrations (e.g., oven door slamming)—maintains consistent brightness, no flickering during timer/temp updates (critical for tracking countdowns).
Long Lifespan (50,000+ Hours): High-quality white LEDs and heat-resistant components match the 8–10 year service life of most ovens—eliminates frequent display replacements, reducing maintenance hassle for users.
4. Easy Integration & Versatility
Common Cathode Polarity: Works with standard driver ICs (e.g., TM1637, HT1621, MAX7219) widely used in oven controllers—simplifies circuit design for manufacturers and integrates seamlessly with oven firmware (e.g., timer counting, temp sensing).
Easy Assembly: Designed for PCB direct-mounting, compatible with automated production lines—speeds up oven manufacturing and ensures consistent display alignment in control panels.
Multi-Color Options: Beyond ultra bright white, available in red (for alerts), blue (modern aesthetics), green (eco-aligned designs), amber, and orange—flexible for other home appliances (e.g., red for microwave “done” alerts, green for fridge temps).
RoHS Compliant: Free from lead, mercury, and harmful substances—safe for kitchen use and export to global markets (EU, North America, Asia), meeting home appliance safety standards.
