Title (EN) SECURITY DISPLAY ASSEMBLY
(FR) ENSEMBLE AFFICHAGE DE SECURITE
Abstract:
(EN) The present invention relates to a security display assembly (10; 50) comprising a display (12; 52) for providing a display image and a hologram (14; 54) for providing a holographic image. The hologram is integrated into the display and occupies essentially the same or less area as the display. Integrating the hologram into the display makes counterfeiting of a product provided with the security display assembly more difficult. It also saves space on the product onto which the security display assembly is provided. The invention also relates to a smart card (20) comprising such a security display assembly.
(FR) L'invention concerne un ensemble affichage de sécurité (10,50) comportant un affichage (12,52) qui fournit une image et un hologramme (14, 54) qui fournit une image holographique. L'hologramme est intégré dans l'affichage et occupe sensiblement une surface inférieure ou égale à celle de l'affichage. L'intégration de l'hologramme dans l'affichage rend la contrefaçon d'un produit doté d'un ensemble affichage de sécurité plus difficile, et elle permet d'économiser de l'espace sur le produit où est placé l'ensemble affichage de sécurité. L'invention porte également sur une carte intelligente (20) pourvue d'un ensemble affichage de sécurité de ce type.
