Ultra Bright White 4 Digit 0.36" 7 Segment LED Display
Light-Bo's 4-digit 7-segment LED display features a 0.36-inch
(9.2mm) character height and ultra bright white emission,
engineered for compact precision in digital devices. With slim
outer dimensions (30×14×7.2mm) and a sleek design—yellow segments
on a black surface—it delivers high luminous intensity (100-120mcd)
while maintaining low power consumption. Available in both common
cathode and common anode configurations, this display ensures
stable performance, fast heat dissipation, and uniform segment
illumination, making it ideal for temperature/humidity indicators,
set-top boxes, home appliances, and instrument panels.
Key Features
- Ultra Bright White Emission: Vivid white light ensures clear readability, with options for red,
yellow green, pure green, blue, amber, orange, and yellow to match
custom device aesthetics.
- 4-Digit Compact Design: 0.36-inch (9.2mm) character height and 30×14×7.2mm dimensions fit
seamlessly into space-constrained devices, perfect for set-top
boxes and small home appliances.
- Dual Polarity Options: Available in common cathode (standard) and common anode
configurations, ensuring compatibility with diverse circuit
designs.
- Uniform Illumination: Continuous, evenly lit yellow segments guarantee consistent
brightness across all 4 digits, critical for precision in
temperature and humidity indicators.
- Energy Efficiency: Low forward voltage and optimized current minimize power usage,
paired with fast heat dissipation for long-term reliability.
- Easy Integration: IC compatibility and simple assembly streamline installation into
PC boards, while RoHS compliance ensures safety for household and
industrial use.
