Display panel and method for manufacturing same, and display apparatus

A display apparatus, comprising a power supply component and a display panel, wherein the power supply component is configured to supply power to the display panel;

• the display panel comprises a substrate, an OLED device and a color film layer;
• the OLED device is disposed on a side of the substrate, and the color film layer is disposed on a side of the OLED device distal from the substrate;
• an orthographic projection of the color film layer onto the substrate at least covers an orthographic projection of a light-emitting layer of the OLED device onto the substrate;
• in a first environment, the color film layer is in a colorless and transparent state;
• in a second environment, at least partial region of the color film layer is in a colored and transparent state, and a color of the region in the colored and transparent state is the same as a light-emitting color of a target OLED device;
• the target OLED device being an OLED device covered by an orthographic projection of the region in the colored and transparent state onto the substrate;
• and an ambient light luminance in the second environment is greater than an ambient light luminance in the first environment.

A method for manufacturing a display panel, comprising:

• forming an OLED device on a side of a substrate;
• and
• forming a color film layer on a side of the OLED device distal from the substrate, wherein an orthographic projection of the color film layer onto the substrate at least covers an orthographic projection of a light-emitting layer of the OLED device onto the substrate;
• in a first environment, the color film layer is in a colorless and transparent state;
• in a second environment, at least partial region of the color film layer is in a colored and transparent state, and a color of the region in the colored and transparent state is the same as a light-emitting color of a target OLED device, the target OLED device being an OLED device covered by an orthographic projection of the region in the colored and transparent state onto the substrate;
• and an ambient light luminance in the second environment is greater than an ambient light luminance in the first environment.
