1. A display module, comprising:
a liquid crystal display panel, comprising a first substrate, a second substrate, and a first liquid crystal layer, wherein the first substrate is disposed opposite to the second substrate, the first liquid crystal layer is located between the first substrate and the second substrate, the first liquid crystal layer comprises a cholesteric liquid crystal, and the cholesteric liquid crystal is configured to have a conical helix texture when an electric field is applied, to reflect light matched with a helical pitch of the conical helix texture; and
a light scattering layer, which is located on a side of the liquid crystal display panel and is configured to be able to scatter light reflected by the liquid crystal display panel,
wherein the light scattering layer comprises a scattering layer, the scattering layer is divided into a first light adjusting region and a second light adjusting region located in a same plane, and the scattering layer comprises a third substrate, a fourth substrate, and a light adjusting function layer, wherein the third substrate is disposed opposite to the fourth substrate, the light adjusting function layer is located between the third substrate and the fourth substrate, and the light adjusting function layer comprises a polymer dispersed liquid crystal located in the first light adjusting region, and a matrix and scattering particles located in the second light adjusting region, wherein the scattering particles are dispersed in the matrix.
