Abstract: This application provides a touch display panel for reducing capacitive load. A package substrate includes a first metal layer and a second metal layer. The second metal layer includes conductive patterns that are arranged in a matrix form. The conductive patterns each output a first sensing signal when sensing a touch operation. Each conductive pattern includes a first area and a second area. The first area includes first metal sub-conducting wires extending in the first direction. A plurality of second metal conducting wires extending in the second direction, any second metal conducting wire is connected to one conductive pattern and is configured to transmit the first sensing signal to a touch controller.
