Patents by Inventor Heung-Su Cho

Heung-Su Cho 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: 8754877
    Abstract: A liquid crystal panel unit, a display device, and a method of manufacturing the same, in which the display device includes: a display panel that includes a display region; a gate driver that applies a gate signal to the display region; a data driver that applies a data signal to the display region; a vertical synchronization signal line that transfers a vertical synchronization start signal to the gate driver; a data signal line that transfers the data signal to the data driver; and an isolation pattern that is arranged between the vertical synchronization signal line and the data signal line. The isolation pattern intercepts an electromagnetic field that is generated and prevents image degradation.

  • Patent number: 8345026
    Abstract: A display apparatus includes a display panel, a flexible printed circuit board, a first data driver, and second data driver. The display panel includes a display area in which an image is displayed in response to a data voltage and a peripheral area adjacent to the display area. The flexible printed circuit board is attached to the peripheral area and includes a plurality of flexible circuit lines. The first data driver is mounted on the flexible printed circuit board to directly receive image data through a part of the flexible circuit lines and convert the image data into the data voltage. The second data driver is mounted on the peripheral area to directly receive the image data through a remaining part of the flexible circuit lines and convert the image data into the data voltage.

  • Publication number: 20080165099
    Abstract: A liquid crystal display (LCD) and method for driving it that removes residual images from the display during power-off include an LCD panel that displays an image, a power-off residual image removal unit that detects a power-off state using pixel data and a driving voltage supplied from a main body through an interface and generates a residual image removal signal for a liquid crystal arrangement of the panel made when a voltage is not applied thereto, and a data driver outputting the residual image removal signal to remove a residual image from the LCD panel.
