Red/Pure Green LED Display 7 Segment 17mm common cathode for Digital Refrigeration Systems

Ultra Red Green LED

17mm 7-Segment Cathode

Digital Refrigeration LED

7-Segment Cathode 17mm

Red Green Fridge Display

Product Overview

Light-Bo's customized 3-digit 7-segment LED display, featuring a 0.67-inch (17mm) character height and integrated minus sign, is engineered for versatile performance in home appliances and climate control systems. With robust package dimensions (47×22×8mm) and dual-color options—ultra bright red (620-625nm) and pure green (515-525nm)—it delivers clear visibility for both positive and negative values (thanks to the minus sign). Configured as common cathode (with common anode also available), this display balances high luminous intensity (80-100mcd) with low power consumption, making it ideal for air conditioner controls, refrigerator indicators, and heating/cooling systems.

Key Features

3-Digit with Minus Sign: Unique design includes a minus sign for displaying negative values (e.g., temperature below zero), critical for climate control systems.

Dual Color Options: Ultra bright red (620-625nm, 1.8-2.3V) and pure green (515-525nm, 2.8-3.3V) cater to diverse appliance aesthetics and functional needs, with additional colors available (blue, ice blue, white, etc.).

Optimal Size: 0.67-inch (17mm) character height and 47×22×8mm dimensions ensure readability without occupying excess space in appliance panels.

High Visibility: 80-100mcd luminous intensity and white segments on a black surface (with protective film) guarantee clarity in bright or dim environments.

Energy Efficient: Low forward current (5-10mA/LED) minimizes power usage, ideal for long-term operation in home appliances.

Easy Integration: Common cathode configuration (common anode optional), IC compatibility, and simple assembly streamline installation into PC boards.

Durable & Compliant: Stable performance, long lifespan, and RoHS certification ensure reliability in household and climate control applications.
