Super Bright Red 0.36-Inch (9.2mm) 3-Digit 7-Segment Common Anode LED Display for Temperature/Humidity Indicators

Super Bright Red 0.36-Inch (9.2mm) 3-Digit 7-Segment Common Anode LED Display for Temperature/Humidity Indicators

Product Overview
Introducing the Super Bright Red 0.36-Inch 3-Digit 7-Segment Common Anode LED Display—a precision numeric solution engineered for temperature/humidity indicators, home appliances, and audio equipment. Designed to prioritize visibility, energy efficiency, and seamless integration, this display excels at delivering clear, reliable readouts for daily environmental metrics: room temperature (e.g., “23°C”), indoor humidity (e.g., “55% RH”), or process values (e.g., “180” for timer).
Its 9.2mm character height ensures readability from 0.5–1.5 meters (typical distance for countertop indicators or appliance panels), while the slim 22.5×14×7.2mm form factor fits into space-constrained designs—from mini humidity sensors to audio amplifier front panels. The yellow epoxy black surface enhances contrast with super bright red light, cutting through bright ambient light (e.g., sunlight, kitchen overheads) without eye strain.
With common anode polarity, low power consumption, and RoHS/REACH compliance, this display balances durability, eco-friendliness, and performance—ideal for 24/7 operation in temperature/humidity trackers and daily-use electronics.

Key Features (Temperature/Humidity Indicator-Optimized)
1. Superior Visibility for Environmental Readouts
Super Bright Red Illumination: Red light (high luminous intensity) stands out in bright environments (e.g., sunlit living rooms, busy workshops) — critical for quick, accurate checks of temperature/humidity (e.g., verifying “30°C” heatwaves or “70% RH” high humidity).
Yellow Epoxy Black Surface: The yellow epoxy base under the black surface softens harsh red light (reducing eye fatigue) while boosting contrast between segments and background—ensures digits (0-9) and decimal points (e.g., “24.5°C”) stay sharp, no glare or washout.
Even Segment Lighting: Luminous intensity is uniformly distributed across all segments (no “hot spots” or dim edges) — guarantees consistent readability of fine values (e.g., “51% RH” vs. “52% RH”) that matter for comfort or process control.
2. Compact & Industrial-Grade Design
Slim 22.5×14×7.2mm Dimensions: Optimized for space-constrained devices—fits into portable temperature/humidity monitors, slim smart thermostats, or audio equipment front panels without requiring redesigns.
Industrial Standard Size: Follows global 0.36-inch 3-digit display footprints—enables drop-in replacement for outdated displays (e.g., upgrading old green indicators to red in existing humidity panels) without modifying PCBs, saving time and cost.
Common Anode Polarity: Works with standard driver ICs (e.g., MAX7219, TM1638, HT1621) widely used in temperature/humidity indicators—simplifies circuit design, no need for custom polarity adapters.
3. Energy Efficient & Durable
Low Power Consumption (Extremely Low Current): Minimizes energy draw (typical 5-10mA/LED), extending battery life for portable indicators (e.g., handheld humidity meters) and reducing electricity use for plugged-in devices (e.g., wall-mounted thermostats).
Long Lifetime (50,000+ Hours): High-quality red LED chips withstand continuous use, matching the 8–10 year lifespan of most home appliances and indicators—reducing maintenance downtime (critical for 24/7 process indicators).
Stable Performance: Withstands temperature fluctuations (-10°C to 50°C, typical for indoor/outdoor use) and minor vibrations (e.g., audio equipment bass, appliance fan movement)—maintains brightness, no flickering during value updates.
4. Versatility & Compliance
RoHS/REACH Compliant: Free from lead, mercury, and harmful substances—meets strict global environmental standards, safe for home use and export to markets like the EU, North America, and Asia.
Multi-Color Options: Beyond super bright red, available in blue (modern aesthetics), green (normal status cues), white (neutral readouts), amber, orange, and yellow—flexible for functional needs (e.g., red for “high temp” alerts, green for “normal” humidity).
