Hsien-Wen Lo 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: 11322427
    Abstract: A chip on film package including a chip and a flexible film. The chip includes bumps disposed on the chip and is mounted on the flexible film. The flexible film includes first vias, second vias, upper leads and lower leads. The first vias and the second vias penetrate the flexible film and are arranged on two opposite sides of a reference line respectively. A distance between one of the first vias and one of the second vias, which are closer to a first side of the chip, is longer than that between another one of the first vias and another one of the second, which are further from the first side. The upper leads are disposed on the upper surface connected between the vias and the bumps. The lower leads are disposed on the lower surface and connected to the vias.

  • Patent number: 11177230
    Abstract: An electronic device includes a substrate and first bumps. The first bumps are disposed on the substrate and arranged in a first bump row. Each first bump has a first end and a second end opposite to each other. Centers of the first ends of the first bumps are on a first axial line. A first axial coordinate of a center of the second end of a respective first bump relative to a second axial line perpendicular to the first axial line is XA(1+?AYA), in which XA is a first axial coordinate of the center of the first end of the respective first bump relative to the second axial line, YA is a second axial coordinate of the center of the second end of the respective first bump relative to the first axial line, and ?A is a slope coefficient of the respective first bump.

  • Patent number: 10699662
    Abstract: An integrated circuit for driving a display panel is provided. The integrated circuit includes a gamma mapping unit and a mura compensation unit. The gamma mapping unit is configured to receive a gray level of an image data, map the gray level to a gamma code according to at least one gamma table, and output the gamma code. The mura compensation unit is configured to receive the gamma code, and compensate the gamma code according to at least one de-mura table to generate a compensation result after the gamma mapping unit performs the step of mapping the gray level to the gamma code. The integrated circuit drives the display panel according to the compensation result. In addition, a method for driving a display panel is also provided.
