1. An organic light-emitting display panel, comprising a substrate and a plurality of pixel units on a side of the substrate, the pixel unit comprising an organic light-emitting diode (OLED),
wherein the substrate has a first pixel density area and a second pixel density area, wherein a density of pixel units in the first pixel density area is greater than a density of pixel units in the second pixel density area; and in the second pixel density area, a light-emitting surface of the OLED protrudes along a light-emitting direction of the OLED.
