Abstract
Embodiments of the present disclosure relate to a touch panel and a touch display panel, wherein touch electrodes including bodies and wings are arranged so as to interlock with each other to thus reduce a difference in sensing sensitivity depending on position and a movement direction, thereby improving uniformity of touch sensing. In addition, the body and wing of the touch electrode can be arranged so as to be varied in length/width depending on the position thereof, so that the boundary area between the touch electrodes is increased, thereby improving the intensity of a touch-sensing signal, and so that sensing time is reduced, thereby enhancing the performance of touch sensing.
Claims16
A touch display device comprising:
- a panel comprising a plurality of subpixels, a plurality of first touch electrodes, a plurality of second touch electrodes arranged thereon, and an encapsulation layer arranged on the plurality of subpixels, wherein the plurality of first touch electrodes and the plurality of second touch electrodes are arranged in the same layer on the encapsulation layer;
- a plurality of touch routing lines connected to the plurality of first touch electrodes and the plurality of second touch electrodes, disposed along an inclined surface of the encapsulation layer, and electrically connected to a plurality of touch pads disposed in a non-active area of the panel;
- and
- a touch-driving circuit configured to drive the plurality of first touch electrodes and the plurality of second touch electrodes,
- wherein each of the plurality of first touch electrodes comprises a first body arranged in a first direction, and a plurality of first wings arranged in a second direction intersecting the first direction, and connected to the first body,
- wherein each of the plurality of second touch electrodes comprises a second body arranged in the first direction, and a plurality of second wings arranged in the second direction and connected to the second body,
- wherein two first touch electrodes arranged adjacent to each other, among the plurality of first touch electrodes, are directly connected to each other,
- wherein two second touch electrodes arranged adjacent to each other, among the plurality of second touch electrodes, are electrically connected to each other by at least one first connection pattern arranged in a layer different from the second touch electrodes, and
- wherein the first body and the second body are alternately arranged in the second direction, and the plurality of first wings and the plurality of second wings are alternately arranged in the first direction.
