Display panel and method for manufacturing same, and display apparatus

A method for manufacturing a display panel, the method comprising:

• forming a light-emitting structure layer on a surface of a substrate, wherein the light-emitting structure layer comprises a plurality of OLED devices distributed on the substrate;
• each OLED device has a light-emitting structure which comprises an anode layer, a light-emitting layer and a cathode layer that are sequentially stacked on the substrate;
• and
• the cathode layer has a patterned area which is located in a light-transmitting display area of the display panel;
• the cathode layer in the patterned area comprises a plurality of cathode structures that are spaced apart from each other;
• and an orthographic projection of each of the cathode structures onto the substrate covers an orthographic projection of the light-emitting structure of at least one of the OLED devices onto the substrate.

A display apparatus, comprising a display panel and a power supply component configured to supply power to the display panel, wherein the display panel comprises a substrate and a light-emitting structure layer, the light-emitting structure layer comprises an anode layer, a light-emitting layer and a cathode layer that are sequentially stacked on the substrate;

• the light-emitting structure layer comprises a plurality of OLED devices distributed on the substrate;
• each OLED device has a light-emitting structure;
• the cathode layer has a patterned area;
• the cathode layer in the patterned area comprises a plurality of cathode structures which are spaced apart from each other;
• an orthographic projection of each of the cathode structures onto the substrate covers an orthographic projection of the light-emitting structure of at least one of the OLED devices onto the substrate;
• wherein the patterned area is located in a light-transmitting display area of the display panel.
