Abstract: Provided is a touch display device including a folding area in an active area. The same pattern of touch electrodes can be maintained in both a reference area and a folding area and cracks on touch electrodes in the folding area, by applying a pattern structure of a touch insulation film disposed in the folding area. Therefore, the degradation of touch sensing performance, caused by cracks on the touch electrodes in the folding area, can be prevented and touch sensing sensitivity can be uniform in the reference area and the folding area, thereby improving touch sensing performance of the touch display device including the folding area.

Abstract: Embodiments of the present disclosure relate to a touch sensing unit and a touch display device, in which touch routing lines can be arranged so as not to overlap signal lines supplying a signal for driving a display and the area of an electrode located between the signal line and in which the touch routing line can be reduced, thereby reducing parasitic capacitance between the signal line and the touch routing line. In addition, it is possible to further reduce noise due to the signal lines and to improve the performance of touch sensing by distributing noise due to the signal lines through touch dummy electrodes positioned between the touch electrodes and the touch routing lines so as to overlap the signal lines.

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.

Abstract: Disclosed are a display device comprising panel portions and a driving method thereof, which are capable of dividing the display panel into two or more panel portions and adding a touch mode between the display modes of each panel portion, thereby improving the frequency of the touch sensing or the touch report rate. The display device comprising panel portions and the driving method thereof can reduce the pulse width of the signals from 4H 8phase to 2H 4phase by using an oxide TFT and maintain or reduce the number of the signal lines applied to the gate driver of the partial display panel, thereby having the advantages in terms of the bezel.
