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.

Abstract: Exemplary flexible coverlenses and the methods of making them are described. The methods may include exposing a surface of a substrate layer to a surface treatment plasma to form a treated surface of the substrate layer. A silicon-containing adhesion layer may be deposited on the treated surface of the substrate layer. A silane-containing adhesion promoter may be incorporated on the silicon-containing adhesion layer. The method may also include forming a hardcoat layer on the silicon-containing adhesion layer, where the silane-containing adhesion promoter is bonded to both the hardcoat layer and the silicon-containing adhesion layer. The exemplary flexible coverlenses made by the present methods are less susceptable to folding fatigue along a bending or folding axis of the coverlens.

Abstract: Implementations described herein generally relate to 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. The flexible cover lens film comprises a multi-layer hardcoat disposed on a substrate layer. The substrate layer has a thickness between 2 μm to 100 μm, and the multi-layer hardcoat has a thickness between 1 μm to 10 μm. The multi-layer hardcoat comprises 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. In terms of 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: Embodiments of the disclosure generally provide methods of forming a capacitor with high capacitance and low leakage as well as a good interface control for thin film transistor (TFT) applications. In one embodiment, a thin film transistor structure includes a capacitor formed in a thin film transistor device. The capacitor further includes a common electrode disposed on a substrate, a dielectric layer formed on the common electrode and a pixel electrode formed on the dielectric layer. An interface protection layer formed between the common electrode and the dielectric layer, or between the dielectric layer and the pixel electrode. A gate insulating layer fabricated by a high-k material may also be utilized in the thin film transistor structure.
