Ultra Bright Red Single Digit 7 Segment LED Display Common Cathode
Product Overview
Ultra Bright Red 0.4-Inch (10.16mm) Single-Digit 7-Segment Common
Cathode LED Display—a precision-engineered numeric solution
tailored for digital weighing scale indicators and compact digit
displays. Designed to prioritize readability, durability, and space
efficiency, this single-digit module excels at showing weight
values in commercial and home weighing scenarios—from kitchen food
scales to industrial parcel scales.
Its 0.4-inch (10.16mm) character height ensures clarity from
0.5-1.5 meters (typical weighing scale viewing distance), while the
ultra-compact 9.8*18.7*5.1mm form factor fits seamlessly into
multi-digit weighing scale panels. The white segments on a black
surface boost contrast with ultra bright red light, ensuring
visibility even in bright ambient light. With common cathode
polarity, low power consumption, and RoHS compliance, it balances
reliability, energy efficiency, and global safety standards—ideal
for 24/7 weighing scale operation.
