Array substrate comprising electromagnetic touch structure and touch display panel

The embodiment of the utility model discloses an array substrate comprising an electromagnetic touch structure and a touch display panel. The array substrate comprises a substrate base plate; the gate metal layer and the source drain metal layer are arranged on the substrate, the gate metal layer comprises a plurality of gate lines, the source drain metal layer comprises a plurality of source signal lines, the gate lines extend in the first direction, and the source signal lines extend in the second direction; the buffer layer is arranged on the source-drain metal layer; the sensing metal layer is arranged on the buffer layer; the source-drain metal layer further comprises a first induction coil extending in the second direction. The induction metal layer comprises a second induction coil extending in the first direction, and the orthographic projection of the second induction coil on the substrate is overlapped with the orthographic projection of the grid line on the substrate. According to the embodiment, the laminated structure and the preparation process are simple, the production cost is effectively reduced, the screen integration level is improved, the touch performance and the user experience are improved, the frame of the touch display panel is reduced, and the thinning and the convenience of a product are realized.
