Abstract: Embodiments described and discussed herein generally relate to flexible or foldable display devices, and more specifically to flexible cover lens assemblies. In one or more embodiments, a flexible cover lens assembly contains a glass layer, an impact absorption layer disposed on the glass layer, a moisture barrier layer disposed on the impact absorption layer, a substrate disposed on the moisture barrier layer, a wet hardcoat layer having a nano-indentation hardness in a range from about 0.4 GPa to about 1.5 GPa and disposed on the substrate, an adhesion promotion layer disposed on the wet hardcoat layer, an anti-reflectance layer disposed on the adhesion promotion layer, a dry hardcoat layer having a nano-indentation hardness in a range from about 1 GPa to about 5 GPa and disposed on the anti-reflectance layer, and an anti-fingerprint coating layer disposed on the dry hardcoat layer.

Abstract: Flexible display devices, such as flexible cover lens films, are discussed and provided herein. The flexible cover lens film has good strength, elasticity, optical transmission, wear resistance, and thermostability. The cover lens film includes a hard coat layer with a thickness from about 5 μm to 40 μm, an impact absorption layer with a thickness from about 20 μm to 110 μm, and a substrate layer with a thickness from about 10 μm to 175 μm and is disposed between the hard coat layer and the impact absorption layer. By combining the hard coat layer and the impact resistant layer, the cover lens film is both flexible and strong with hardness from 6H to 9H.
