    Abstract: Disclosed is a touch sensitive display apparatus which decreases a load of each of a plurality of touch electrodes and reduces a load deviation between the plurality of touch electrodes, thereby enhancing image quality. The touch sensitive display apparatus comprises a touch sensitive panel. The touch panel comprises a plurality of touch electrodes comprising at least a first touch electrode. The first touch electrode comprises a plurality of first touch electrode lines that are parallel to each other. A first touch signal line is connected to the plurality of first touch electrode lines of the first touch electrode, and the first touch electrode is driven for image display and touch sensing via the first touch signal line. A first connecting line is in a different layer than the first touch electrode lines, and the first connecting line is connected to the plurality of first touch electrode lines.

    Abstract: Disclosed are a driving circuit, a touch display device, and a method of driving the same. The touch display device for sensing a user's touch force may sense a capacitance change due to a change in a contact area on a display panel after a section in which a sensing value of a touch force based on a change in capacitance between first electrodes and a second electrode becomes a saturated state, thereby sensing the user's touch force even in a section where the change in the capacitance between the first electrodes and the second electrode is small. Accordingly, it is possible to expand a range in which a user's touch force can be sensed and acquire data on a user's touch force linearly indicated in the expanded range, so that touch force leveling becomes easy and various inputs based on the touch force can be processed.

    Abstract: A transparent touch display apparatus including a device substrate, a touch electrode and a routing line. The device substrate may include an emission area and a transmission area. The touch electrode may be disposed on the transmission area of the device substrate. The routing line may be disposed outside the emission area and the transmission area of the device substrate. A transmittance of the touch electrode may be higher than a transmittance of the routing line. Thus, in the transparent touch display apparatus, the reliability of the touch detection may be improved.
