Light Up Every Number: The 0.56 Inch 4-Digit 7 Segment LED Display

From the clock on your microwave to the price board at a gas station, crisp digital numbers are everywhere — and behind most of them sits a simple, brilliant component: the 7 segment LED display. This 0.56 inch 4-digit seven-segment LED display shows numbers and symbols clearly in bright, high-contrast light, making it the dependable choice for instruments, appliances and information boards.

What Makes This 4-Digit 7 Segment Display Stand Out

• Four clear digits — display values up to 9999 with a single compact module (19.0 × 50.3 × 8.0mm).
• Five vivid color options — Red, Green, Blue, White and Yellow to match any panel design.
• Wide 120° viewing angle — readable from almost any position.
• Low drive current — just 20mA for energy-efficient operation.
