Hanwook Baek 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: 10056045
    Abstract: In an exemplary embodiment, each horizontal and vertical conductor of a TFT array may be in electrical contact with a first and second control system. Initially, the entire display is driven by the first control system. When/if a failure occurs in the first control system, it is powered down and the second control system maintains operation of the entire display. Each control system may contain a set of source/gate drivers, display interface board, and power supply. A reversionary button may allow the user to manually switch between control systems. Alternatively, failure may be detected by the display interface boards or a graphics processor.
    Type: Grant

  • Patent number: 8243109
    Abstract: A two-dimensional panel, particularly a liquid crystal display device, has a maximum display area with a width of (T×M) addressable channels. The addressable channels are addressed through a plurality of T source channel integrated circuits (ICs), with each source channel IC having M source channels. The number of addressable channels exceeds the number of channels of data in an image display data array having a width of W pixels, each pixel comprising P subpixels in the width dimension. The excess addressable channels are distributed symmetrically across the width dimension of the displayed image. In other embodiments the number of addressable channels is less than the number of channels of data and excess channels of data are excluded symmetrically across the width dimension of the displayed image. Further embodiments distribute excess addressable channels symmetrically across the height dimension or exclude excess channels of data symmetrically across the height dimension.

  • Publication number: 20100329471
    Abstract: An ambient noise compensation system having an automatic gain control to adjust the volume of a desired sound in a listening area. A sound pick-up may be placed in the listening area to capture the sound level, including both the desired sound and ambient noise. A measured value is then determined based on the sound level received by the sound pick-up. The measured value may then be compared to a predictive value to determine an acceptable range. The gain control automatically adjusts the volume of the desired sound to maintain the measured sound within the acceptable range.
