1. A display panel, comprising:
a base substrate;
a detection circuit, located on a side of the base substrate, and comprising a transistor and photosensitive detection components electrically connected to the transistor, wherein an orthographic projection of the transistor on the base substrate and an orthographic projection of each of the photosensitive detection components on the base substrate do not overlap with each other;
a planarization layer, located on a side of the detection circuit facing away from the base substrate, and comprising: a first surface facing away from the base substrate at a position where the transistor is located, and a second surface facing away from the base substrate at a position where each of the photosensitive detection components is located, wherein the first surface and the second surface are located on a same plane;
light-emitting devices, located on a side of the planarization layer facing away from the detection circuit; and
a pixel circuit, electrically connected to the light-emitting devices, wherein an orthographic projection of the pixel circuit on the base substrate, an orthographic projection of each of the light-emitting devices on the base substrate, and an orthographic projection of the detection circuit on the base substrate do not overlap with each other.
