Chil Son 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).

  • Patent number: 9851608
    Abstract: A liquid crystal display (LCD) including: a first electrode disposed on a first substrate; an insulating layer disposed on the first electrode; a second electrode disposed on the insulating layer, overlapping the first electrode, and including a plurality of branch electrodes; and a second substrate opposing the second substrate. Liquid crystal molecules of a liquid crystal layer disposed between the substrates are aligned to have pretilt angles in an alignment direction. The branch electrodes include a main branch portion forming a first angle with the alignment direction and a first center portion forming a second angle with the alignment direction, respectively. The branch electrodes include an outermost branch electrode, and the outermost branch electrode includes the main branch portion forming a first angle with the alignment direction and a second center portion forming a fourth angle with the alignment direction.

  • Publication number: 20150269902
    Abstract: A liquid crystal display includes: a first substrate, on which a first pixel, a second pixel and a third pixel are defined, where the first pixel, the second pixel and the third pixel display different colors from each other; a first electrode disposed on the first substrate; a second electrode disposed on the first substrate; an insulating layer disposed between the first electrode and the second electrode; a second substrate disposed opposite to the first substrate; and a liquid crystal layer injected between the first substrate and the second substrate, where a first thickness of the insulating layer in the first pixel is different from a second thickness of the insulating layer in the second pixel.
