Abstract: Implementations described herein generally relate to a flexible display devices, and more specifically to flexible cover lens films. The flexible cover lens film has improved strength, elasticity, optical transmission, and anti-abrasion properties, and contains a multi-layer hardcoat disposed on a substrate layer. The substrate layer has a thickness of 2 μm to 100 μm and the multi-layer hardcoat has a thickness of 1 μm to 30 μm. The multi-layer hardcoat contains a first layer deposited using a wet deposition process, a second layer deposited using a dry deposition process, and one or more adhesion promotion layers. For optical properties, the multi-layer hardcoat has a total transmission greater than 88%, a haze of about 1% or less, and a yellowness index of b*

Abstract: An adaptive backlight module and a method and system for producing an adaptive backlight module are described herein. The method of producing an adaptive backlight module includes: forming at least one enhancement film on a first substrate, forming a polarizer on the enhancement film, forming a diffuser by forming a liquid crystal layer between a first electrode on the first substrate and a second electrode on a second substrate, and connecting the diffuser to a light source.

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 6 H to 9 H.
