Patents by Inventor Seok-Joon Hong

Seok-Joon Hong 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).

  • Substrate and display apparatus having the same
    Patent number: 8014060
    Abstract: In a substrate for a display apparatus, the substrate includes a base substrate and a shielding layer formed on a surface of the base substrate. The shielding layer has an energy bandgap corresponding to a reference wavelength of external light. Thus, the shielding layer blocks light having wavelength equal to or less than the reference wavelength, so that a wavelength band of light may be adjusted.
    Type: Grant
    Filed: September 2, 2009
    Date of Patent: September 6, 2011
    Assignee: Samsung Electronics Co., Ltd.

  • Method of forming amorphous silicon layer and method of fabricating LCD using the same
    Patent number: 7998843
    Abstract: Methods and systems for forming an amorphous silicon layer are disclosed for one or more embodiments. For example, a substrate may be provided, and an amorphous silicon layer, in which a ratio of Si—H to Si—H2 has a value equal to or less than 4 to 1, may be formed on the substrate using chemical vapor deposition equipment.
