Ultra Bright Red 4-Digit 7-Segment LED Clock Display - 0.8-Inch
(20mm), Common Cathode, 8.5mm Slim Profile
Product Main Image Area
Front Luminous Shot: Clear display of ultra bright red digits (e.g., "12:34" for clock
scenarios) with white segments and black surface, emphasizing high
contrast and brightness.
Dimension Labeled Diagram: Marked 71.6×25.8×8.5mm outer dimensions and 20mm (0.8-inch)
character height, visualizing the slim 8.5mm depth for
space-constrained devices.
Side Profile Shot: Highlight the 8.5mm ultra-thin thickness to showcase compatibility
with slim panels (e.g., set-top boxes, compact thermostats).
Application Mockup: Integrated into a clock, instrument panel, or set-top box to
demonstrate real-world use.
Parameter Close-Up: Engraved "Common Cathode (CC)" and "RoHS" logos on the back,
reinforcing compliance and polarity clarity.

Key Selling Points
1. Ultra Bright Red Luminosity & High Contrast for All-Time
Readability
90-110mcd ultra bright red emission: Cuts through ambient light (e.g., living room ceiling lights,
office lamps) while remaining easy on the eyes in dark spaces
(e.g., bedroom night clocks). Perfect for clock displays where
readability at any time of day is critical.
White segments + black surface: Eliminates reflection and enhances digit clarity-even from
off-angles. Unlike low-contrast displays, it avoids misreading "6"
as "9" or "8" as "3," ensuring accuracy for time, temperature, or
numeric indicators.
2. 8.5mm Slim Profile & Compact Size for Slim Devices
Ultra-thin 8.5mm depth: Fits seamlessly into slim enclosures like set-top boxes (where
internal space is limited), wall-mounted thermostats, or compact
instrument panels. No need to modify device housing to accommodate
bulkier displays.
71.6×25.8mm optimized footprint: The 4-digit layout balances screen
real estate and space efficiency-ideal for displaying time
("10:05"), temperature ("25ºC"), or channel numbers ("120") without
taking up excess panel space.
3. Energy Efficiency & Long-Term Reliability
Low power consumption (5-10mA/LED): Minimizes energy draw, making it suitable for battery-powered
devices (e.g., portable thermometers) or 24/7 operated equipment
(e.g., always-on set-top boxes). Reduces long-term electricity
costs and extends battery life.
Stable performance: Withstands voltage fluctuations (1.8-2.2V adaptive) and
temperature ranges of -40ºC to 85ºC (industrial grade), ensuring no
flickering, segment dropout, or brightness degradation-even in
harsh environments (e.g., hot kitchen appliances, cold garage
thermostats).
4. Easy Integration & Wide Compatibility
IC compatible: Works with mainstream 7-segment driver ICs (74HC595, TM1638,
MAX7219), eliminating the need for custom driver development.
Simplifies circuit design for manufacturers and speeds up product
launch cycles.
Easy-to-assemble: Supports both through-hole and SMD mounting
(optional), adapting to automated production lines or manual
assembly. Standardized pinouts ensure consistent installation and
reduce assembly errors.

Target Applications
1. Clock & Time-Related Devices
Digital wall clocks: Display hour/minute (e.g., "09:45") or 12/24-hour format.
Kitchen timers: Show countdown time (e.g., "00:59") for cooking/baking.
Set-top boxes & media players: Indicate playback time (e.g., "30:15") or channel numbers (e.g.,
"0120").
2. Home Appliances
Smart thermostats: Display indoor temperature (e.g., "22ºC"), set temperature (e.g.,
"25ºC"), or humidity (e.g., "50%").
Small kitchen appliances (air fryers, microwaves): Show cooking time (e.g., "01:20") or target temperature (e.g.,
"180ºC").
Washing machines/dryers: Indicate remaining cycle time (e.g., "25min") or program codes
(e.g., "04").
3. Industrial & Instrument Panels
Temperature/humidity monitors: Display real-time environmental data (e.g., "28ºC/60%RH") in
factories, warehouses, or greenhouses.
Equipment status indicators: Show operation hours (e.g., "125h"), production counts (e.g.,
"500pcs"), or voltage levels (e.g., "220V").
Procurement & Delivery Information
Quality Assurance
Raw Material Control: Uses high-grade LED chips (Taiwan Epistar) and PC plastic
(heat-resistant up to 120ºC) for the black surface, ensuring
durability and consistent luminosity.
100% Inspection: Each unit undergoes brightness testing, voltage testing, and
high-low temperature cycle testing (-40ºC~85ºC) before shipment to
eliminate defective products.
Warranty: 1-year warranty for non-human damage. If quality issues occur,
free replacement or refund is provided (batch number and test
report required).

Frequently Asked Questions (FAQ)
Q: Is this display suitable for outdoor use?
A: It is designed for indoor use (e.g., homes, offices) due to its
non-waterproof design. For outdoor applications, we recommend our
waterproof-coated version (customizable upon request).
Q: Can it display decimal points?
A: Yes-each digit can be equipped with a decimal point (optional)
to support temperature (e.g., "25.5ºC") or time (e.g., "10:05.5")
display.
Q: What is the viewing angle?
A: The horizontal/vertical viewing angle is ≥120°, ensuring clear
readability from the side (e.g., a clock mounted on a wall viewed
from a sofa).
