Patents by Inventor Un Nyoung Sa

Un Nyoung Sa has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9336923
    Abstract: Disclosed are polymer resins, including polymer resin sheets, having good electroconductivity and a method for manufacturing the same. The polymer resins exhibit flexibility and show electroconductivity on their surface as well as along their thickness, and thus can be used as electromagnetic wave-shielding materials having impact- and vibration-absorbing properties as well as conductivity.
    Type: Grant
    Filed: January 29, 2015
    Date of Patent: May 10, 2016
    Assignee: 3M Innovative Properties Company
    Inventors: Jeongwan Choi, Un Nyoung Sa, Won-Sik Kim

  • Publication number: 20090169852
    Abstract: Disclosed is an electroconductive adhesive tape having different adhesion values on both surfaces thereof. A method for producing the same is also disclosed. The adhesive tape has different adhesion values on both surfaces thereof, elasticity, and electroconductivity along the longitudinal direction as well as the transverse direction. Thus, the adhesive tape can be used in electronic components, as an electromagnetic wave-shielding tape that permits easy attachment/detachment.

  • Patent number: 7352423
    Abstract: A liquid crystal display using a compensating film includes a liquid crystal panel having upper and lower substrates, and a liquid crystal layer interposed between; a first compensating film formed over an inner surface of at least one of the upper substrate lower substrates; a second compensating film formed over an outer surface of at least one of the upper and lower substrates; and first and second polarizing plates attached over the second compensating film and on an outer surface of the other one of the upper lower substrates such that a first optical transmission axis of the first polarizing plate is perpendicular to a second optical transmission axis of the second polarizing plate. The compensating film is formed inside the liquid crystal panel, thereby preventing light leakage at a viewing angle and improving the viewing angle characteristics.
