Abstract: Embodiments of the present disclosure relate to flexible display devices, including dual-sided wet hardcoats for flexible cover lens structures, and related methods and coating systems. The flexible cover lens film has beneficial strength, elasticity. optical transmission, and anti-abrasion properties. In one or more embodiments. a cover lens structure for display devices includes a substrate layer including a first side and a second side. The cover lens structure includes a first wet hardcoat layer deposited on the first side of the substrate layer, and a second wet hardcoat layer deposited on the second side of the substrate layer. The cover lens structure includes one or more adhesion promotion layers formed above the second side. and a dry hardcoat layer formed above the second side.
