Various embodiments of the present invention provide a flexible display device capable of realizing a narrow bezel-type or bezel-free display device and simultaneously realizing improved types of design, facilitating bending of a bezel area so as to realize a narrow bezel-type or bezel-free display device, and minimizing damage to an area to be bent.

Flexible display device and method of manufacturing the same

Apparatus, systems and methods for improving strength of a thin glass cover for an electronic device are disclosed. In one embodiment, the glass member can have improved strength by forming its edges with a predetermined geometry and/or by chemically strengthening the edges. Advantageously, the glass member can be not only thin but also adequately strong to limit susceptibility to damage. In one embodiment, the glass member can pertain to a glass cover for a housing for an electronic device. The glass cover can be provided over or integrated with a display, such as a Liquid Crystal Display (LCD) display.

Techniques for Strengthening Glass Covers for Portable Electronic Devices

The central tension varies non-linearly with the thickness of the glass. The glass article may be used as cover plates or windows for portable or mobile electronic devices such as cellular phones, music players, information terminal (IT) devices, including laptop computers, and the like.

Strengthened glass articles and methods of making

A tempered glass substrate of the present invention is a tempered glass substrate, which has a compression stress layer on a surface thereof, and has a glass composition comprising, in terms of mass %, 40 to 71% of SiO2, 3 to 21% of Al2O3, 0 to 3.5% of Li2O, 7 to 20% of Na2O, and 0 to 15% of K2O.

Tempered glass substrate and method of producing the same

An alkali aluminosilicate glass article, said alkali aluminosilicate glass having a surface compressive stress of at least about 200 MPa, a surface compressive layer having a depth of at least about 30 µm, a thickness of at least about 0.3 mm and an amphiphobic fluorine-based surface layer chemically bonded to the surface of the glass. In one embodiment the glass has an anti reflective coating applied to one surface of the glass between the chemically strengthened surface of the glass and the amphiphobic coating. In another embodiment the surface of the chemically strengthened glass is acid treated using a selected acid (e.g., HCL, H2SO4, HClO4, acetic acid and other acids as described) prior to placement of the amphiphobic coating or the anti reflective coating.

Damage resistant glass article for use as a cover plate in electronic devices

Embodiments of this disclosure pertain to articles that exhibit scratch-resistance and improved optical properties. In some examples, the article exhibits a color shift of about 2 or less, when viewed at an incident illumination angle in the range from about 0 degrees to about 60 degrees from normal under an illuminant. In one or more embodiments, the articles include a substrate, and an optical film disposed on the substrate. The optical film includes a scratch-resistant layer and an optical interference layer. The optical interference layer may include one or more sub-layers that exhibit different refractive indices. In one example, the optical interference layer includes a first low refractive index sub-layer and a second a second high refractive index sub-layer. In some instances, the optical interference layer may include a third sub-layer.

Low-color scratch-resistant articles with a multilayer optical film

One or more aspects of the disclosure pertain to an article including a film disposed on a glass substrate, which may be strengthened, where the interface between the film and the glass substrate is modified, such that the article has an improved average flexural strength, and the film retains key functional properties for its application. Some key functional properties of the film include optical, electrical and/or mechanical properties. In one or more embodiments, interface exhibits the effective adhesion energy is about less than about 4 J/m2. In some embodiments, the interface is modified by the inclusion of a crack mitigating layer between the glass substrate and the film.

Laminate articles with moderate adhesion and retained strength

One or more aspects of the disclosure pertain to an article including a film disposed on a glass substrate, which may be strengthened, where the interface between the film and the glass substrate is modified, such that the article has an improved average flexural strength, and the film retains key functional properties for its application. Some key functional properties of the film include optical, electrical and/or mechanical properties. In one or more embodiments, the interface exhibits an effective adhesion energy of about less than about 4 J/m2. In some embodiments, the interface is modified by the inclusion of a crack mitigating layer containing an inorganic material between the glass substrate and the film.
