Patents by Inventor Shien-Tsung Wu

Shien-Tsung Wu 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: 11898744
    Abstract: A quantum structure thin film includes an excitation layer, a first substrate and a second substrate. The excitation layer includes a plurality of quantum structures which are one of quantum dots and quantum rods, and which are made of one of cesium lead halide and organic ammonium lead halide. The first substrate and the second substrate are respectively disposed on two opposite sides of the excitation layer. One of the first substrate and the second substrate includes an inner layer, a buffer layer, and an outer layer that are sequentially disposed on the excitation layer in such order. Also disclosed herein is a quantum structure light-emitting module including the quantum structure thin film.

  • Publication number: 20190221721
    Abstract: A quantum structure light-emitting module includes a quantum structure thin film and a light-emitting unit. The quantum structure thin film includes first and second substrates, and an excitation layer that is disposed between the first and second substrates, and that includes multiple quantum structures, which are quantum dots or quantum rods and which are made of cesium lead halide or organic ammonium lead halide. The light-emitting unit includes a first light-emitting element emitting a blue light that enters the excitation layer to excite the quantum structures to emit a green light, and a second light-emitting element emitting a red light. The blue, red and green lights are mixed and exit the second substrate.

  • Patent number: 10156343
    Abstract: An optical film includes a blocking layer, and a main body unit including first and second base layers, a working layer and a side surface. The first base layer has a light incident surface and a first surface opposite to the light incident surface. The second base layer has a second surface facing the first surface and a light exiting surface opposite to the second surface. The working layer is interconnected between the first and second surfaces, and includes a plurality of quantum dots, which can be excited by a first light incident on the light incident surface to emit a second light. The side surface surrounds the light incident, first, second and light exiting surfaces. The blocking layer is bonded to the side surface.

  • Publication number: 20180129100
    Abstract: The present invention provides a light guiding structure, a display device having the same and a manufacturing method therefor. The light guiding structure includes: a light guiding layer; and a reflecting layer including a reflecting material and a substrate having a first surface and a second surface, wherein the first surface of the substrate has at least one micro-structure, and the reflecting material at least partially covers the first surface of the substrate to form the reflecting layer. The manufacturing method includes: providing a substrate having a first surface and forming at least one micro-structure on the first surface of the substrate by a roll embossing process to form a reflecting layer; providing a light guiding layer having a bottom surface; and providing a bonding layer configured to bond the bottom surface of the light guiding layer and the first surface of the reflecting layer together.
