Patents by Inventor Ding-Wei LIU

Ding-Wei LIU 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: 11467684
    Abstract: The disclosure provides a touch display panel including a substrate and a first mesh electrode. The first mesh electrode is disposed on the substrate and includes a plurality of first extending portions, a plurality of second extending portions, and a plurality of first disconnection regions. The first extending portions are arranged along a first direction and extend in a second direction. The first direction intersects with the second direction. The second extending portions are arranged along the second direction and extend in the first direction. The first disconnection regions are arranged along the first direction and extend in the second direction. The first disconnection regions overlap the second extending portions and do not overlap the first extending portions.
    Type: Grant
    Filed: April 28, 2021
    Date of Patent: October 11, 2022
    Assignee: HannStar Display Corporation

  • Patent number: 11143906
    Abstract: A reflective LCD panel includes a color filter substrate, an array substrate, a liquid crystal layer and a polarizing film. The array substrate and the color filter substrate are disposed oppositely. The liquid crystal layer is disposed between the color filter substrate and the array substrate and has an alignment direction. The polarizing film is disposed on the color filter substrate, and color coordinates of the polarizing film in the CIE1976 color space are (a, b), wherein 0.05?a?0.2 and ?5?b?0. The liquid crystal layer has a birefringence difference ?n, the liquid crystal layer has a thickness (d), when the reflective LCD panel is in a white frame, 2?n*d=?? is satisfied, ?? is the optical path difference obtained when a forward light vertically enters the liquid crystal layer and is reflected by the array substrate, and 120 nm??n*d?170 nm.
