  • Publication number: 20180150165
    Abstract: The present embodiments relate to an all-in-one switch device as well as a touch display apparatus and a display panel including such an all-in-one switch device. The all-in-one switch device includes a switching transistor electrically connected between a pixel electrode and a data line, and a sensor pattern connected between a first electrode and a second electrode of the switching transistor. One device is enough to provide both a switching function for display driving and a sensor function for sensing a touch position and/or a fingerprint, a separate touch sensor having a large size is unnecessary, and it is possible to precisely sense a touch position and/or a fingerprint without being affected by parasitic capacitance, even in a situation where a system has a structure or a circuit in which touch sensing based on capacitance is impossible.

  • Publication number: 20170300146
    Abstract: The present embodiments relate to a driving circuit and a touch display apparatus for sensing a user's touch position and touch force with respect to a display panel, and further relate to a driving method thereof. The touch display apparatus may include a plurality of first electrodes that are configured to be embedded in a display panel, and a second electrode that is configured to be positioned outside the display panel. The touch display apparatus may read a force sensing signal from the second electrode through a signal detecting unit that is electrically connected to the second electrode. Therefore, it is possible to sense a touch force without separating a force sensing signal from a signal received from the first electrode, and to sense a user's touch force through the driving of the second electrode regardless of the driving mode of the first electrode.
