Title (EN) LAMINATING THIN STRENGTHENED GLASS TO CURVED MOLDED PLASTIC SURFACE FOR DECORATIVE AND DISPLAY COVER APPLICATION
(FR) STRATIFICATION DE VERRE MINCE RENFORCÉ SUR UNE SURFACE EN PLASTIQUE MOULÉE INCURVÉE POUR UNE APPLICATION DE PROTECTION D’ÉCRAN ET DE DÉCORATION
Abstract:
(EN) A process comprises cold-forming a flat glass substrate into a non-planar shape using a die. The cold-formed glass substrate is bonded to a non-planar rigid support structure at a plurality of non-planar points using the die. Bonding methods include injection molding the non-planar rigid support structure, and direct bonding. An article is also provided, comprising a cold-formed glass substrate having opposing major surfaces and a curved shape, the opposing major surfaces comprising a surface stress that differ from one another. The cold-formed glass substrate is attached to a rigid support structure having the curved shape. The cold-formed glass substrate includes an open region not in direct contact with the non-planar rigid support structure, and the open region has a curved shape maintained by the non-planar rigid support structure.
(FR) L’invention concerne un procédé qui comprend la formation à froid d’un substrat en verre plat en une forme non plane à l'aide d'une matrice. Le substrat en verre formé à froid est lié à une structure de support rigide non plane à une pluralité de points non plans à l'aide de la matrice. Les procédés de liaison comprennent le moulage par injection de la structure de support rigide non plane, et la liaison directe. L'invention concerne également un article qui comprend un substrat en verre formé à froid ayant des surfaces principales opposées et une forme incurvée, les surfaces principales opposées qui comportent une tension de surface différant les unes des autres. Le substrat en verre formé à froid est fixé à une structure de support rigide ayant la forme incurvée. Le substrat en verre formé à froid comprend une zone ouverte qui n'est pas en contact direct avec la structure de support rigide non plane, la zone ouverte ayant une forme incurvée maintenue par la structure de support rigide non plane.
