Abstract: Provided is a display panel, including a substrate, an OLED device disposed on a side of the substrate, and a color film layer 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; and an ambient light luminance in the second environment is greater than an ambient light luminance in the first environment.
