Title
(EN) REPLACEABLE COVER LENS FOR FLEXIBLE DISPLAY
(FR) VERRE DE PROTECTION REMPLAÇABLE POUR ÉCRAN FLEXIBLE
Abstract
(EN) Implementations described herein generally relate to flexible display devices and cover lens assemblies with flexible cover lens. In one or more embodiments, a cover lens assembly is provided and includes a first flexible cover lens, a second flexible cover lens, and a sacrificial adhesion disposed between the first flexible cover lens and the second flexible cover lens. The first flexible cover lens includes a first hard coat layer having a hardness in a range from about 4H to about 9H and a first substrate. The second flexible cover lens includes a second hard coat layer having a hardness in a range from about 2H to about 9H. The first substrate is disposed between the first hard coat layer and the sacrificial adhesion layer.
(FR) Selon des modes de réalisation, la présente invention a trait d'une manière générale à des dispositifs d'affichage flexibles, et à des ensembles de verres de protection comportant un verre de protection flexible. Dans un ou plusieurs modes de réalisation, un ensemble de verres de protection comprend un premier verre de protection flexible, un second verre de protection flexible, ainsi qu'une adhérence sacrificielle située entre le premier verre de protection flexible et le second verre de protection flexible. Ledit premier verre de protection flexible inclut une première couche de revêtement dur ayant une dureté comprise entre environ 4H et environ 9H, et un premier substrat. Ledit second verre de protection flexible comporte une seconde couche de revêtement dur ayant une dureté comprise entre environ 2H et environ 9H. Le premier substrat se trouve entre la première couche de revêtement dur et la couche d'adhérence sacrificielle.
