1. An organic light-emitting diode (OLED) display panel, comprising a display area and a camera-under-panel (CUP) area in the display area, wherein the CUP area comprises a plurality of pixel areas disposed at intervals and a light-transmitting area between two adjacent pixel areas, and the OLED display panel comprises:
a thin film transistor (TFT) array substrate comprising a TFT disposed in the pixel areas; and
a light-emitting device layer disposed on the TFT array substrate, wherein the light-emitting device layer comprises a first light-emitting device disposed in the pixel areas and connected to the TFT and a second light-emitting device disposed in the light-transmitting area and connected to the first light-emitting device;
wherein the second light-emitting device comprises a first transparent electrode, a second OLED functional layer disposed on the first transparent electrode, and a second transparent electrode disposed on the second OLED functional layer; and
wherein the first light-emitting device comprises a first electrode, a first OLED functional layer disposed on the first electrode, and a second electrode disposed on the first OLED functional layer, the first transparent electrode is connected to the first electrode, and the second transparent electrode is connected to the second electrode.
