LIGHT-BO’s COB-type customized triple-digit 7-segment LED display is engineered to deliver exceptional visibility and reliability for home appliances and climate control systems. With a 0.75-inch (18.95mm) character height and compact dimensions (55×22.5×7mm), it features crisp white segments on a black surface (protected by a durable film) and supports vibrant multi-color emission—including red, yellow, pure green, blue, white, amber, and orange. Designed with a common cathode configuration, this display balances high luminous intensity (70-140mcd) with low power consumption, making it ideal for air conditioner controls, refrigerator indicators, and heating/cooling systems.
Vibrant Multi-Color Options: Emitting colors include red (625-635nm), yellow (585-590nm), pure green (515-525nm), plus blue, white, amber, and orange—perfect for color-coded controls (e.g., heating vs. cooling).
Large, Clear Digits: 0.75-inch (18.95mm) character height ensures easy readability, enhanced by high luminous intensity (70-140mcd) and uniform segment illumination.
Durable Design: White segments on a black surface with a protective film for scratch resistance, paired with stable performance and a long lifespan.
Energy Efficient: Low forward voltage (1.8-3.3V/LED) and current (5-10mA/LED) minimize power usage, ideal for energy-conscious appliances.
Easy Integration: Common cathode configuration, IC compatibility, and simple assembly streamline installation into air conditioners, refrigerators, and control panels.
RoHS Compliant: Meets global environmental standards, ensuring safety for home and commercial use.
