1. A touch display panel, comprising:

  • a first substrate;

    a second substrate;

    a third substrate, wherein the second substrate is positioned between the first substrate and the third substrate;

    a medium display layer positioned between the first substrate and the second substrate;

    a plurality of pixels positioned between the first substrate and the medium display layer, wherein each of the pixels comprises a pixel electrode and a common electrode, and at least one of the pixel electrode and the common electrode has a plurality of slits;

    a plurality of viewing angle control electrode units positioned between the second substrate and the medium display layer, and arranged in sequence along a first direction in a X axis;

    a plurality of touch receiving electrode units positioned between the second substrate and the third substrate, and arranged along in sequence a second direction in a Y axis, wherein the plurality of touch receiving electrode units are partially overlapping with the viewing angle control electrode units in a vertical direction in a Z axis projected on the first substrate, and the viewing angle control electrode units and the touch receiving electrode units form a touch unit; and

    a plurality of first connection lines and a plurality of second connection lines, wherein the first connection lines and the second connection lines are provided between the first substrate and the medium display layer, each of the first connection lines is respectively electrically connected to the first viewing angle control electrode series corresponding thereto, and each of the second connection lines is respectively electrically connected to the second viewing angle control electrode series corresponding thereto.
