Organic light-emitting display panel, preparation method thereof, display apparatus and electronic device

A method for preparing an organic light-emitting display panel, comprising:

• providing a substrate;
• forming a plurality of pixel units on the substrate, the pixel unit comprising an organic light-emitting diode (OLED), wherein a first pixel density area and a second pixel density area are formed on the substrate, 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 a light-emitting surface of the OLED in the second pixel density area protrudes along a light-emitting direction of the OLED.

A display apparatus, comprising an organic light-emitting display panel, wherein the organic light-emitting display panel comprises a substrate and a plurality of pixel units disposed 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.
