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.
Procurement & Delivery Information
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.
