Field: nan (nan)
Classification: CPC H | IPC H

Claim 13:
14. An array substrate, comprising:
a base substrate;
an excitation light source on a side of the base substrate; and
a sub pixel on a side, facing away from the base substrate, of the excitation light source;
wherein the sub pixel at least comprises:
a first-kind sub pixel;
wherein the first-kind sub pixel comprises:
a first quantum dot conversion layer, a first recycling component layer and a first color film layer sequentially located on the side, facing away from the base substrate, of the excitation light source;
wherein the first recycling component layer is configured to limit at least part of light with a wavelength, smaller than a wavelength of emergent light of the first-kind sub pixel, into the first quantum dot conversion layer;
a refractive index of the first quantum dot conversion layer is equal to a refractive index of the first recycling component layer;
in a wave band smaller than a wavelength of the emergent light of the first-kind sub pixel, the refractive index of the first recycling component layer is greater than a refractive index of the first color film layer; and
in a wave band greater than or equal to the wavelength of the emergent light of the first-kind sub pixel, the refractive index of the first recycling component layer is smaller than the refractive index of the first color film layer.
