Abstract: Provided is an organic-inorganic-hybrid thin film, which is provided in the form of a layered structure to prevent the scratching of the surface of a variety of kinds of displays, such as those of smartphones, tablet PCs, and laptop computers, and to fabricate ITO hard coating films, gas-barrier plates for flexible displays, and cover windows, and to a method of manufacturing the same, and more particularly, the organic-inorganic-hybrid thin film is provided in the form of a layered structure exhibiting the high light transmittance, mechanically flexible properties, lightweightness, and chemical resistance of a curable resin, and also ensuring the scratch resistance, heat dissipation performance, gas-barrier properties, and inherent refractive index matching of inorganic particles, thus exhibiting optical compensation effects, thereby increasing final surface hardness and satisfying barrier properties and index matching properties.

Abstract: Provided is a refractive-index-matching thin film, which is an inorganic crystal thin film, wherein a matching layer including inorganic films having different refractive indices is formed on the surface of a substrate and, more particularly, to a refractive-index-matching thin film, which is configured such that a matching layer including one or more inorganic films having different refractive indices is formed on the surface of a substrate made of a polymer, ceramic, metal or combinations thereof, thus protecting the surface of flexible displays such as curved and bendable displays.

Abstract: The present invention discloses a matable and dematable electrical connecting structure characterized by comprising: a female coupling member having a first connecting portion; a male coupling member having a second connecting portion; and a connecting unit coupling the female coupling member and the male coupling member and electrically connecting the first and second connecting portions, wherein the connecting unit includes an inner conductive material which is electrically connected to the first connecting portion and is provided on the inner wall of an insert hole formed in the female connecting member, a column including a conductive material which is electrically connected to the second connecting portion, protruding from the male connecting member, and can be inserted in the insert hole, and one or more elastic pin including a surface of a conductive material which is extending in an outward direction from the column and elastically contacting the inner conductive material.
