Key Traits	High luminous intensity, low power consumption, long lifespan (≥50,000 hours)

Key Selling Points
1. Extreme Heat Resistance for Oven/Cooker Environments
+105ºC~+120ºC operating temperature: Engineered with high-temperature-resistant materials (heat-resistant PC face, LED chips) to withstand the ambient heat near oven heating elements or gas cookers. Unlike standard displays (max. +85ºC) that fade or fail in high heat, this display maintains stable performance-critical for oven timers/temperature controls that operate for hours at high temperatures.
No thermal brightness degradation: Even at +120ºC, luminous intensity (90-110mcd typical) remains consistent, ensuring "200ºC" or "05:00" (timer) is readable without squinting, avoiding cooking errors (e.g., undercooking/overcooking due to unreadable temperature).
2. High Visibility & Practical Design for Kitchen Use
Ultra bright white + black face: The white segments cut through kitchen glare (e.g., under-cabinet lights, sunlight through windows) and the black matte face eliminates reflection. Perfect for busy kitchens where users glance at the oven quickly while prepping other food.
Big viewing angle: Horizontal/vertical viewing angles ≥120°, so the display is readable even when standing to the side of the oven (no need to lean directly in front)-enhancing user safety (avoids leaning too close to hot appliances).
3. Energy Efficiency & Long-Term Reliability
Low power consumption: Optimized circuit design uses only 5-10mA per segment, reducing the oven's overall energy draw (critical for energy-efficient appliance certifications like ENERGY STAR).
Stable performance & good consistency: Same-batch displays have ≤5% deviation in voltage and brightness, ensuring uniform visual output if multiple displays are used (e.g., a cooker with separate oven and stovetop controls). Long lifespan (≥50,000 hours) means no frequent replacement-even for ovens used daily.
4. Easy Integration for Appliance Manufacturers
IC compatible: Seamlessly works with common appliance control ICs (e.g., TM1637, MAX7219) for timer/temperature display, eliminating the need for custom driver development. Shortens appliance R&D cycles and reduces engineering costs.
SMD pin type: Designed for automated SMT assembly lines, enabling high-speed production (20,000+ units/day) with minimal manual intervention. The 44×16×11.85mm compact size fits standard appliance control panel cutouts-no need to redesign housing.

Target Applications
1. Oven & Cooker Controls
Multifunction digital oven timers: Display cooking time ("04:30"), preheat countdown ("00:59"), or temperature ("190ºC").
Gas cookers/induction cooktops: Show heat levels ("5"), timer settings ("01:00"), or safety alerts (e.g., "HOT" via numeric code).
Toaster ovens/slow cookers: Indicate cooking mode (numeric codes for "BAKE"/"ROAST") and remaining time ("02:15").
2. Other Home Appliances
Microwaves: Display cook time ("02:00") or power levels ("70%").
Electric pressure cookers: Show pressure levels (numeric codes) or timer ("03:20").
Smart kitchen scales: Indicate weight ("1.2kg") or temperature ("25ºC") for food prep.

Frequently Asked Questions (FAQ)
Q: Can it display decimal points for precise temperature (e.g., "185.5ºC")?
A: Yes-each digit can be equipped with a decimal point (customizable) to support precise temperature or timer readings (e.g., "00:30.5" for half-minute increments).
Q: Is the black face scratch-resistant?
A: The face uses matte PC material with a scratch-resistant coating, so it won't easily show marks from cleaning (e.g., wiping with a damp cloth after kitchen use).
Q: Does it require a heat sink for use near oven heating elements?
A: No-the display's internal structure and materials are designed to dissipate heat naturally. It can be mounted up to 10cm from oven heating elements without additional heat sinks.
