Abstract: Embodiments disclosed herein relate to a touch display panel and a touch display device. By arranging a shielding structure, which is connected to a touch electrode in a region where a touch line and a data line overlap each other or is applied with a shielding signal corresponding to a touch driving signal from an outside circuit, between the touch line and the data line, it is possible to prevent direct capacitance from being formed between the touch line and the data line, and to prevent the capacitance formed due to the data line from causing noise on a touch sensing signal. In addition, by arranging a touch load reduction layer between the shielding structure and the touch line, it is also possible to reduce the capacitance between the touch line and the data line arranged in the horizontal direction, thereby improving touch sensing performance.

Abstract: Embodiments of the disclosure relate to touch display devices. The difference in parasitic capacitance due to the difference in length between the touch routing lines may be reduced by separately arranging touch electrode lines in the active area and connecting the touch routing line connected with each portion of a touch electrode line with the touch routing line connected with each portion of another touch electrode line. Therefore, it is possible to reduce loads and the differences in touch sensing depending on the connection structure and position of the touch routing line by driving the touch electrode line in a double-routing structure. By so doing, the performance of touch sensing may be enhanced.

Abstract: The present disclosure relates to a touch display device and a driving method of the same, and more particularly, to a touch display device, in which a touch is sensed by only utilizing electrodes and a line structure for display so that there is no need to provide a touch panel additionally or form additional touch electrodes in a display panel, thereby reducing the size (thickness) of the touch display device and simplifying a manufacturing process of the touch display device, and a driving method of the same.

Abstract: In a touch display panel and a touch display device, a shielding pattern including the common electrode (COM) used as the touch electrode (TE) is disposed between a touch line (TL) and a data line (DL), and the touch line (TL) and the data line (DL) are arranged so as not to overlap each other in a boundary area between shielding patterns. The parasitic capacitance between the touch line (TL) and the data line (DL) can be reduced to improve the performance of touch sensing. In addition, the arrangement of the touch lines (TL) and data lines (DL) in the boundary area between shielding patterns is repeated at regular intervals to prevent an image abnormality.

Abstract: Embodiments of the disclosure relate to touch display devices. A shielding pattern to which a constant voltage is applied is placed between the touch routing line and the encapsulation part without overlapping the touch routing line. Thus, it is possible to block the noise due to the signal line positioned under the encapsulation part by the electric field generated by the shielding pattern. Further, the metal disposed on the same layer as the shielding pattern in the planarized area of the encapsulation part may be used as a touch routing line, reducing the resistance and width of the touch routing line and hence the planarized area of the encapsulation part. Thus, it is possible to provide a touch display device for which an increase in the non-active area has been reduced and display noise has been reduced upon touch sensing.

Abstract: Embodiments of the present disclosure are related to a touch display device, as a plurality of first line parts disposed on a first sensor layer and a plurality of second line parts disposed on a second sensor layer are alternated to make a touch line, at least a portion of different touch lines can be disposed to be overlapped each other, thus a plurality of touch lines can be disposed while reducing or minimizing a reduction of an aperture ratio or a transmittance of a subpixel due to an arrangement of the touch line. Accordingly, a touch sensitivity can be enhanced by further disposing touch electrodes, or the touch display device having a large area with many channels can be implemented easily by further disposing touch lines.
