AI Technical Summary
Existing anti-counterfeiting elements using single reflective facets struggle with non-uniform distribution of emergent light angles and low pattern resolution, necessitating multiple facets to achieve uniformity, which complicates production and reduces effectiveness.
The use of curved-surface structures arranged in a feature area, where each structure is shaped along a first direction to emit light over a fan-shaped range, ensuring uniform angle distribution and higher resolution, mimicking the effect of multiple facets while simplifying production.
This approach achieves a more uniform and stable appearance pattern with increased viewable angles, enhancing the dynamic effect's resolution and stability, making it harder to counterfeit.
