Abstract

The OLED display panel includes a thin film transistor (TFT) array substrate and a light-emitting device layer. The TFT array substrate includes a TFT disposed in pixel areas. The light-emitting device layer is disposed on the TFT array substrate, and includes a first light-emitting device disposed in the pixel areas and connected to the TFT and a second light-emitting device disposed in a light-transmitting area and connected to the first light-emitting device. The second light-emitting device includes 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.
