Ultra Bright White 4-Digit 7-Segment LED Display - Common Anode for Oven Controllers & Home Appliances
  
  Product Main Image Area

  
  High-Temp Scene Mockup: The display integrated into an oven controller, showing a cooking time ("03:30") or temperature ("180ºC") to emphasize compatibility with high-heat environments.
  Luminous Close-Up: Ultra bright white digits (e.g., "220ºC") on a black face, demonstrating high contrast and no glare-critical for reading while operating hot appliances.
  Dimension Labeled Diagram: Clear marking of 44×16×11.85mm package dimensions and 9.92mm (0.38-inch) character height, visualizing its compact fit for appliance control panels.
  SMD Pin Detail: Shot of the SMD pin type to highlight easy surface-mount assembly for automated production lines.
  Environmental Test Shot: The display functioning in a simulated high-temperature environment (labeled "+120ºC") to showcase thermal resistance.
  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.
  Quality Assurance
  High-Temp Testing: Every unit undergoes a 24-hour continuous operation test at +120ºC to verify thermal stability-only passing units are shipped.
  Material Compliance: Uses RoHS/REACH-certified LED chips and heat-resistant plastics, meeting global appliance safety standards (e.g., CE, UL, CCC).
  Warranty: 1.5-year warranty for non-human damage. If the display fails due to heat or material defects, free replacement is provided (batch number and test report required).

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.
