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.
