1. A display panel, comprising:
a substrate;
a light-emitting layer disposed on the substrate, wherein the light-emitting layer comprises a plurality of light-emitting units, and a first gap is defined between each two of the light-emitting units; and
an adjustment structure arranged on one side of the light-emitting layer away from the substrate, wherein the adjustment structure comprises a plurality of black photosensitive particles in the adjustment structure;
wherein when the display panel is in a bright state, light emitted from the light-emitting units illuminate the black photosensitive particles, and the black photosensitive particles move to positions corresponding to the first gaps;
wherein the black photosensitive particles comprise a base and a modification layer surrounding the base, a material of the modification layer comprises a chemical substance with photocatalytic properties, a material of the base comprises black carbon powder or graphite, and a material of the modification layer comprises bismuth oxyiodide.
