Patents by Inventor Woo Hyun BAE

Woo Hyun BAE 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: 11314359
    Abstract: A touch sensing electrode structure includes sensing electrodes, each of which including a plurality of unit patterns, and traces electrically connected to the sensing electrodes. The traces include at least two trace lines and trace bridges connecting the at least two trace lines to each other. An electrode visibility due to a pattern deviation is reduced and a reliability of the trace is improved by the trace bridge.

  • Patent number: 10770518
    Abstract: An OLED-integrated touch sensor includes an organic light emitting diode (OLED) device, and a touch electrode on a surface of the OLED device. The touch electrode includes a driving electrode formed on one surface of a base layer and a receiving electrode formed on an opposing surface of the base layer relative to the one surface. The touch electrode is combined with the OLED device such that the driving electrode faces the surface of the OLED device.

  • Patent number: 10379643
    Abstract: The present invention provides an electrode structure for a touch panel and a method for fabricating the same, in which a unit wire and another unit wire continued thereto are continued while the contact area between the unit wires decreases from the entire line width, thereby achieving irregular patterns. In the electrode structure for the touch panel and the method for fabricating the same, a metal wire formed with continuous unit wires has an irregular pattern where the contact area between any one unit wire and another unit wire continued thereto decreases, from the entire line width, by a non-contact size value k obtained by dividing a line width by an arbitrary real number.

  • Patent number: 10088966
    Abstract: A touch screen panel includes a base substrate, a sensing pattern layer on the base substrate, the sensing pattern layer including a plurality of sensing patterns formed on the base substrate, an insulation layer on the sensing pattern layer, and a bridge electrode formed on the insulation layer to electrically connect unit patterns isolated from each other of the sensing pattern layer. The insulation layer and the bridge electrode satisfy parameters according to specific equations so that a visibility of the bridge electrode on the insulation layer is decreased and an image visibility is improved.

  • Patent number: 10061454
    Abstract: A method for fabricating a thin film touch screen panel includes forming an adhesive layer on a convex portion of an arcuate spherical-shaped glass, adhering a base film on the adhesive layer, and forming a transparent electrode laminate on the base file, wherein the convex portion of the glass is flattened by applying heat to the adhesive layer after forming the adhesive layer or adhering the base film, thereby the transparent electrode laminate may be formed on the straight flattened glass and the base film, and the process of forming the transparent electrode laminate may be more precisely and reliably performed.
