    Abstract: A display panel having a plurality of subpixels is provided. The display panel includes a base substrate; a plurality of light emitting elements on the base substrate; and a quantum dot layer on a side of the plurality of light emitting elements away from the base substrate. A respective one of the plurality of light emitting elements includes a first light emitting layer and a second light emitting layer sequentially stacked. The first light emitting layer is configured to emit a first light of a first wavelength range. The second light emitting layer is configured to emit a second light of a second wavelength range. The plurality of light emitting elements are configured to respectively emit a composite light. The quantum dot blocks of different colors are configured to respectively convert the composite light into light of different colors respectively in different subpixels.

    Abstract: The present disclosure relates to a display substrate. The display substrate may include a base substrate; and a plurality of pixels in a display area on the base substrate. At least one of the plurality of pixels includes a first sub-pixel and a third sub-pixel. The first sub-pixel may include an OLED component that emits light of a first color, the third sub-pixel may include a LED component that emits light of a third color, and the first color and the third color are different colors. All sub-pixels including OLED components may be disposed on a same side of the base substrate, and all sub-pixels including LED components may be disposed on another side of the base substrate opposite the side on which the OLED components are disposed.
