Patents by Inventor JunWook YOO

JunWook YOO 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: 11132081
    Abstract: A display panel includes an edge area having a rounded shape and a flat inner area in which a plurality of touch electrodes are disposed. A plurality of driving lines applying a touch driving signal to the plurality of touch electrodes are disposed in the display panel. A touch circuit outputs the touch driving signal applied to the edge area at a voltage level higher than a voltage level of the touch driving signal applied to the inner area.
    Type: Grant

  • Patent number: 10318040
    Abstract: There is provided a touch display device including a display panel including a first electrode for touch sensing, a first support that covers a back surface of an edge area of the display panel, a second support on a back side of the first support and that covers an entirety of the back surface of the display panel, and a touch driver configured to: apply a first electrode driving signal to the first electrode, select one of the first support and the second support as a second electrode, and apply a second electrode driving signal to sense a user's touch pressure applied to the display panel.

  • Patent number: 10282008
    Abstract: A touch display device. A touch display panel includes a source multiplexer switching the transfer of source signals to data lines. In a low power wake-up gesture (LPWG) mode in which a touch input is only sensed in a state in which a display function is off to reduce power consumption, a source multiplexer control signal is provided to set the source multiplexer in an on state, in synchronization with a touch sensing section in which a touch driving signal is provided. This can discharge electric charges generated within the display panel, thereby preventing display defects due to the electric charges.
