Claim 0:
1. A touch display panel, comprising:
an array substrate;
a display medium layer;
a package substrate that is sequentially stacked with the array substrate and the display medium layer, wherein the display medium layer emits light to display an image through cooperation between the array substrate and the package substrate, wherein the package substrate comprises a first surface and a second surface that are disposed opposite each other, wherein the first surface is adjacent to the display medium layer, and wherein the second surface is spaced apart from the display medium layer;
a first metal layer and a second metal layer that are mutually insulated are sequentially disposed on the second surface, wherein the second metal layer comprises a plurality of conductive patterns that are arranged in a matrix form in a first direction and a second direction, wherein the plurality of conductive patterns each output a first sensing signal through self-capacitance when sensing a touch operation, wherein the first direction is perpendicular to the second direction, wherein each conductive pattern comprises a first area and a second area that do not overlap, wherein the first area comprises a plurality of first metal sub-conducting wires extending in the first direction, wherein the second area comprises at least one second metal sub-conducting wire extending in a direction different from the first direction, and wherein the at least one second metal sub-conducting wire is electrically connected to the plurality of first metal sub-conducting wires in the first area; and
a plurality of second metal conducting wires extending in the second direction and that are disposed in the first area corresponding to the first metal layer, wherein each metal conducting wire of the plurality of second metal conducting wires does not overlap the first metal sub-conducting wire in the second direction, wherein at least one second metal conducting wire of the plurality of second metal conducting wires is electrically connected to one conductive pattern and is configured to transmit the first sensing signal to a touch controller, and wherein the touch controller is configured to identify a location of the touch operation based on the first sensing signal.
