Abstract: A touch display panel has a display area and a non-display area and includes pixel units located in the display area and two antenna layers. The pixel units are arranged in an array, and the two antennas are stacked and insulated from each other. Each antenna layer includes a plurality of antenna groups, and each of gaps between adjacent pixel units is provided with an antenna group. Extending directions of the antennas in each antenna layer are same and extending directions of the antennas in the two antenna layers are perpendicular to each other.
