Patents by Inventor Shih-Pin Cheng

Shih-Pin Cheng 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: 12191341
    Abstract: The present invention provides a light emitting panel, which includes: a substrate, at least one light emitting element disposed on the substrate, and a reflective structure layer. The reflective structure layer includes a plurality of first microstructure units disposed on the substrate and distributed around the at least one light emitting element, and a plurality of second microstructure units disposed on and overlapping the first microstructure units. A spacing between adjacent first microstructure units among the first microstructure units is less than a spacing between adjacent second microstructure units among the second microstructure units.
    Type: Grant
    Filed: June 16, 2022
    Date of Patent: January 7, 2025
    Assignee: AU OPTRONICS CORPORATION

  • Patent number: 10209578
    Abstract: A display panel includes a first substrate structure, a second substrate structure and a display medium layer. The first substrate structure includes a first substrate, a transmitting line, a first protrusion structure and a second protrusion structure. The transmitting line, the first protrusion structure and the second protrusion structure are disposed on the first substrate. The second substrate structure includes a second substrate and a first spacer. The first spacer is disposed on the second substrate. The shape of a vertical projection of the first spacer projected on the first substrate is a polygonal shape having a first side, a second side, a third side, a first included angle and a second included angle. The first included angel is between the first side and the third side, and the first included angle is greater than 90 degrees. The second included angle is less than 90 degrees.

  • Patent number: 7520216
    Abstract: A method for manufacturing water-based laser hologram papers has acts of entirely or partially coating water-based varnish on a printed paper substrate, subjecting the paper substrate to a mirror treatment, and entirely or partially molding the paper substrate with laser compressing operations. By substituting PVC or PET plastic membranes with decomposable water-based varnish, the laser hologram paper is environmental friendly to reduce pollution and is also breakable to provide counterfeit-deterring efficiency. Moreover, material cost of the plastic membranes is eliminated to reduce manufacturing cost of the laser hologram papers.
