Luckylight manufactures a complete range of 7-segment LED displays — also known as LED numeric displays or seven-segment displays — in both through-hole and surface-mount packages, from standard brightness to ultra-bright.
Character heights range from compact 0.2 inch up to large-format sizes, including popular options such as 0.3", 0.36", 0.4", 0.56", 0.8", 1.0" and 1.5". Digit configurations cover 1-digit, 2-digit, 3-digit, 4-digit, 5-digit and 6-digit displays. Both common anode and common cathode circuits are available.
Emitting colors include red, green, yellow, white, blue and orange, with bi-color and tri-color versions for applications that need multiple display states in a single package. A wide choice of face and segment color combinations — gray face with white segments, black face with white segments, or black/gray face with colored segments — lets designers balance contrast, readability and front-panel appearance.
The range covers both industrial-grade displays with wide operating temperature ranges for test & measurement, instrumentation and telecom systems, and commercial/consumer-grade displays for POS terminals, home appliances, office and medical equipment.
Customization on Request: Character heights, colors, specialized pin lengths, and standoff heights and spacers can all be tailored to fit your specific enclosure design — send us your drawing or requirements for a quick feasibility review.
