Anti-fingerprint, anti-glare, and depth perception simultaneously provided | Vehicle-mounted cover lens
AFP, AG, AR, and high design in a single cover lens. Guaranteed automotive quality with 3D shape management for all units.
It was difficult to simultaneously apply anti-fingerprint (AFP), anti-glare (AG), anti-reflective (AR) coatings, and a sense of depth design to cover lenses for car navigation systems using conventional methods. Additionally, there was a demand to comply with outgassing regulations for automotive environments and to ensure durability in light resistance tests. We adopted a functional film that incorporates water-repellent and oil-repellent (AFP) components and UV-absorbing components into a double in-mold surface foil, achieving a sense of depth through graphic decoration on the back side. We established a quality assurance system by introducing non-contact displacement gauges for all products, allowing for quantitative management of 3D shapes (warpage) at multiple measurement points. We have simultaneously achieved passing light resistance tests, applying anti-fingerprint coatings, and conducting quantitative management of all products.
