1. An organic light-emitting diode display panel comprising:
a display area for displaying images;
a transparent area for placing a device; and
a wire exchange area, positioned at a wire connecting site between the display area and the transparent area;
wherein the wire exchange area comprises a substrate, an inorganic buffer layer, an active semiconductor layer, a third-metal wire, an inorganic insulating layer, a first-high light-transmissive metal wire, a first-metal wire, an organic planarization layer, a second-high light-transmissive metal wire, an organic opening layer, a cathode layer, and an encapsulation layer which are stacked in sequence,
the first metal wire is electrically connected to the second-high light-transmissive metal wire through a first via hole, the third metal wire is electrically connected to the first-high light-transmissive metal wire through a second via hole, and the first-high light-transmissive metal wire and the second-high light-transmissive metal wire extend to the transparent area.
