Yeon-Hee Yu 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: 8451231
    Abstract: Disclosed herein is a touch screen panel, a method of manufacturing the touch screen panel, and a display having the touch screen panel. Ultrasonic excitation and detection transducers are attached to the front surface of the image display unit of a display, thereby implementing the touch screen panel. The substrate of the display, that is, the upper surface of the image display unit is used as a surface acoustic wave propagation medium, so that it is not required to manufacture the touch screen panel in a separate substrate and to attach the substrate, in which the touch screen panel is manufactured, to the image display unit of the display, thereby not only preventing degradation of image quality but also not increasing the thickness and size thereof.

  • Patent number: 7951527
    Abstract: A method of forming a wire grid polarizing pattern across the relatively large surface area of a display substrate includes using a nano imprint lithograph process wherein wire grid polarizing patterns are formed by bonding a stamp having a stamping area substantially smaller than that of the substrate with successive reticle areas of the substrate, where the substrate has a photosensitive film deposited thereon and where the stamping is such that recesses having a predetermined depth are formed in the photosensitive film, and then filling the recesses with an insulating film and etching it using the insulating film as a mask. Since mechanical misalignment margin is acceptable from one reticle area to the next, a wire grid polarizing pattern with a uniform line width and spacings in each reticle area can be formed on a substrate having a large area.

  • Patent number: 7626177
    Abstract: A method for detecting X-rays using an X-ray detector including an X-ray detecting part includes disposing a heat-circulating part adjacent to the X-ray detecting part. The X-ray detecting part includes light-detecting diodes. The method further includes detecting ambient temperatures of the light detecting diodes, circulating heat in the heat-circulating part based upon a result of the detecting the ambient temperatures of the light detecting diodes, increasing a uniformity of the ambient temperatures of the light-detecting diodes, and detecting X-rays irradiated into the X-ray detector.

  • Publication number: 20080100779
    Abstract: A method of forming a wire grid polarizing pattern across the relatively large surface area of a display substrate is disclosed where the method includes using a nano imprint lithograph process. According to the disclosure, in forming the wire grid polarizing patterns using nano imprint lithography process, wire grid polarizing patterns are formed by bonding a stamp having a stamping area substantially smaller than that of the substrate with successive reticle areas of the substrate, where the substrate has a photosensitive film deposited thereon and where the stamping is such that recesses having a predetermined depth are formed in the photosensitive film, and then filling the recesses with an insulating film and etching it using the insulating film as a mask.
