Product Name

0.32 Inch Single Digit 7 Segment LED Display with RoHS 
The LD3211A/B series are numerical display units that showcase LITEKEY's proprietary 4-element (AlGaInP) high-brightness LED dies. These units boast industry-leading luminous intensity with significantly slower degradation rates, ensuring enduring vivid illumination and maintaining high image quality over extended periods.

Features:
1. Single-line LED numerical displays with 8mm letter height.
2. Approximately 10 times higher luminous intensity compared to conventional products, achieved through the use of 4-element LED dies (particularly in orange color).
3. Maintains the same luminous intensity as conventional products while operating at only 1/10 of the current, leading to substantial energy savings.
4. Rare instances of light-leakage from segments in the compact display packages.
5. Available in both anode common type and cathode common type for each color in the product lineup.
