Ultra White Common cathode 7 Segment LED Display 4 Digit for Oven Controller
Product Overview
This specialized 4-digit 7-segment LED display is engineered to excel in the heat-intensive environments of oven controllers, gas cookers, and cooking timers—featuring ultra white emission for clear, high-contrast readability and extreme temperature resistance (105°C to 120°C). Configured as common cathode for seamless integration into standard home appliance circuits, it balances high performance (high luminous intensity, big viewing angle) with efficiency (low power consumption) and durability (long lifespan, stable performance). Built to meet strict RoHS/REACH compliance standards and compatible with common ICs, it delivers consistent, reliable numeric readouts for critical values like oven temperatures, cooking timers, and heat levels—making it the ideal choice for heat-prone home appliances where standard displays fail.

Core Product Features
1. Extreme High-Temperature Resistance (105°C–120°C)
The display’s robust construction—including heat-resistant epoxy encapsulation and high-temp-tolerant LED chips—enables it to withstand the intense, prolonged heat generated by ovens and gas cookers. Unlike standard LED displays that degrade, flicker, or fail in temperatures above 80°C, this model maintains stable performance even during 2+ hour baking cycles (e.g., oven interiors at 220°C) or near gas cooker flames. This eliminates the risk of unreadable timers or temperature settings, ensuring safety and usability in busy kitchen environments.
2. Ultra White Emission for Clear Visibility
High luminous intensity: The bright, crisp ultra white light cuts through ambient kitchen glare (overhead lamps, oven interior glow) and heat-induced haze, ensuring instant recognition of critical values—such as oven timer countdowns (e.g., "30:00"), target temperatures (e.g., "180°C"), or gas cooker heat levels (e.g., "5").
Big viewing angle: Wide vertical and horizontal viewing angles guarantee readability from off-center positions (e.g., a user stirring a pot on the stovetop while checking the oven timer), eliminating the need to lean close to the appliance.
Good consistency: Light distributes uniformly across all 4 digits and segments, avoiding "dark spots" or uneven brightness. This ensures digits like "8" or "0" are fully legible, preventing misreads of cooking times (e.g., confusing "6" with "9").
3. Energy Efficiency & Long Lifespan
Low power consumption: Minimizes energy draw, making it suitable for 24/7 operated appliances (e.g., always-on oven control panels) or battery-powered cooking timers. Aligns with eco-friendly home appliance standards and reduces long-term electricity costs for users.
Long lifespan: High-quality components—heat-resistant materials, durable LED chips—ensure a service life of 50,000+ hours, even with frequent exposure to high temperatures. This reduces maintenance needs (no frequent display replacements) and lowers total ownership costs for appliances.
4. Easy Integration & Regulatory Compliance
Common cathode polarity: Matches standard circuit designs for oven controllers, gas cookers, and home appliances, eliminating the need for custom voltage inversion or adapter circuits. Simplifies PCB design and speeds up manufacturing for appliance brands.
IC compatible: Works seamlessly with common display driver ICs (e.g., 74HC595, TM1638) used in home appliance electronics, enabling plug-and-play integration without redesigning control systems.
RoHS/REACH Compliant: Free from restricted substances and meets EU REACH regulations for chemical safety. Ensures compliance with global home appliance standards, enabling export to key markets like the EU, North America, and Asia.

Target Applications
Optimized for heat-prone home appliances where durability and readability are critical:
Multifunction Digital Oven Controllers: Displaying cooking timers (e.g., "45:00" for roasting), preheat durations (e.g., "08:00"), or target temperatures (e.g., "200°C").
Gas Cookers: Showing burner heat levels (e.g., "1–5" for low to high) or built-in timer settings (e.g., "15:00" for simmering sauces).
Cooking Timers: Portable or built-in timers for baking, boiling, or grilling (e.g., "10:00" for pasta, "05:00" for eggs).
Other Heat-Resistant Appliances: Air fryers, toasters, or induction cooktops requiring reliable numeric displays near heat sources.
