  • Publication number: 20240130199
    Abstract: A display device includes a first substrate and a second substrate facing each other; and a filling layer disposed between the first substrate and the second substrate. The first substrate comprises a support substrate comprising a display area in which emission areas associated with sub-pixels, are arranged; a light-emitting element layer disposed on one surface of the support substrate; and an encapsulation layer disposed on the light-emitting element layer. The encapsulation layer comprises a first inorganic layer covering the light-emitting element layer; an organic layer disposed on the first inorganic layer and overlapping the light-emitting element layer; and a second inorganic layer disposed on the first inorganic layer and covering the organic layer. A thickness of the first inorganic layer is smaller than a thickness of the second inorganic layer.

  • Publication number: 20240107002
    Abstract: A method for coding image information includes generating prediction information by predicting information on a current coding unit, and determining whether the information on the current coding unit is the same as the prediction information. When the information on the current coding unit is the same as the prediction information, a flag indicating that the information on the current coding unit is the same as the prediction information is coded and transmitted. When the information on the current coding unit is not the same as the prediction information, a flag indicating that the information on the current coding unit is not the same as the prediction information and the information on the current coding unit are coded and transmitted.

  • Patent number: 11925547
    Abstract: The present invention relates to a coating composition for an in-vivo implantable prosthesis including a photoinitiator, a crosslinking agent, and a phosphorylcholine (pc) monomer having an acrylate group, a method of coating an in-vivo implantable prosthesis using the coating composition, and a cosmetic prosthesis coated with the crosslinked polyphosphorylcholine. An in-vivo implantable prosthesis coated with crosslinked polyphosphorylcholine may be manufactured by a simple method of applying a coating composition including a photoinitiator, a crosslinking agent, and a phosphorylcholine (pc) monomer having an acrylate group according to the present invention, and then irradiating uv rays. The crosslinked polyphosphorylcholine coating may provide hydrophilicity for the surface and may also remarkably reduce adsorption of proteins and fibroblasts, which may cause side effects such as capsular contracture.

  • Publication number: 20220218872
    Abstract: Provided is a method for coating an implant using heat, and more particularly to a method for coating only the surface of an implant with a biocompatible polymer by using heat while maintaining physical characteristics of the implant. The method for coating an implant using heat according to the present invention may effectively introduce a biocompatible polymer onto a three-dimensional material surface and thus may overcome the spatial limitations of light, and enables mass-coating and thus may be effectively used in the manufacture of an implant coated with a biocompatible polymer.

  • Publication number: 20190361046
    Abstract: Disclosed is a method for determining malignant melanoma by a scanning probe microscope system with a cantilever, which includes: setting locations of a plurality of measurement points to be measured in a sample tissue; applying force in a predetermined range to each measurement point on the sample tissue through the cantilever and acquiring information on a distance between a probe and the sample tissue depending on force for each measurement point; generating a force-distance graph of measurement points based on distance information depending on the force acquired at the plurality of measurement points; and determining whether the sample tissue is malignant melanoma based on characteristics information of the sample tissue extracted from the force-distance graph.
