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.

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: The present invention generally relates to TFTs and methods for fabricating TFTs. When multiple layers are used for the semiconductor material in a TFT, a negative Vth shift may result. By exposing the semiconductor layer to an oxygen containing plasma and/or forming an etch stop layer thereover, the negative Vth shift may be negated.
