Claim 13:
14. A touch display panel, comprising a display region and a non-display region surrounding the display region, wherein the non-display region comprises a bonding region arranged at one side of the display region along a first direction, and a first bezel region and a second bezel region arranged respectively at two opposite sides of the bonding region along a second direction perpendicular to the first direction;
the touch display panel further comprises a display signal line and a touch signal line; and
the bonding region comprises a first pad and a second pad, the display signal line is coupled to a flexible printed circuit via the first pad, the touch signal line is coupled to the flexible printed circuit via the second pad, and the second pad is arranged at one side of the first pad along the second direction;
wherein the touch display panel further comprises a substrate, and an organic light-emitting unit and a thin film encapsulation layer laminated one on another on the substrate, wherein a barrier layer is arranged at the non-display region in such a manner as to surround the display region, the thin film encapsulation layer comprises a first region and a second region surrounding the first region, a part of the second region is arranged at a side of the barrier layer away from the substrate, a planarization layer is arranged at a side of the second region away from the substrate, and the touch signal line is extracted from the display region and extends through the planarization layer to the bonding region in the non-display region;
wherein an isolation layer is arranged between the display signal line and the touch signal line in the bonding region in a direction away from the substrate, and the isolation layer is arranged at a same layer, and made of a same material, as the planarization layer.
