LTC-2621 optoelectronic Series

The LTC-2621 series from Lite-On Technology Corporation is a lineup of three-digit LED displays available in red, green, and yellow. These displays are designed for use in segmented panel applications, making them ideal for digital clocks, calculators, and other devices that require clear, high-contrast numeric displays.

If you're working on a project that demands precise control over individual segments, these displays offer a straightforward solution. Engineers tend to reach for this series when they need bright, readable digits that can be easily integrated into larger display panels. The red version provides excellent visibility in low-light conditions, while green and yellow options offer better contrast and color differentiation.

One practical observation is that these displays have a relatively wide viewing angle, which means they remain legible from multiple angles—a crucial feature for public-facing displays. Another useful aspect is their modular design; each digit is an independent unit, allowing for flexible layout and easy integration into custom display configurations. Overall, the LTC-2621 series is a reliable choice for anyone needing robust, segmented LED displays in their next project.
