1. A display panel, comprising:
a display area comprising a plurality of pixel areas and a plurality of light transmissive areas, the plurality of pixel areas and the plurality of light transmissive areas being arranged in an array, and the plurality of pixel areas comprising one or more light emitting devices;
a dimming part, wherein the dimming part is arranged on a side of the one or more light emitting devices facing away from a light-emitting surface of the one or more light emitting devices, and at least a part of the dimming part overlaps with at least a part of the light transmissive areas along a thickness direction of the display panel; and
at least one photosensitive component, wherein the photosensitive component is electrically connected to the dimming part, and the photosensitive component is configured to generate a brightness signal based on brightness of light incident from the dimming part and adjust a light transmittance of the dimming part based on the brightness signal.
 
20. A display device, comprising a display panel, wherein the display panel comprises:
a display area comprising a plurality of pixel areas and a plurality of light transmissive areas, the plurality of pixel areas and the plurality of light transmissive areas being arranged in an array, and the plurality of pixel areas comprising one or more light emitting devices;
a dimming part, wherein the dimming part is arranged on a side of the one or more light emitting devices facing away from a light-emitting surface of the one or more light emitting devices, and at least a part of the dimming part overlaps with at least a part of the light transmissive areas along a thickness direction of the display panel; and
at least one photosensitive component, wherein the photosensitive component is electrically connected to the dimming part, and the photosensitive component is configured to generate a brightness signal based on brightness of light incident from the dimming part and adjust a light transmittance of the dimming part based on the brightness signal.
