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.
