1. A display module, comprising a first liquid crystal panel and a light modulation layer, wherein the first liquid crystal panel comprises a first substrate and a second substrate opposite to each other, and a first liquid crystal layer between the first substrate and the second substrate;
the light modulation layer is on a side of the second substrate away from the first substrate, and configured to reflect first colored light; and
liquid crystal in the first liquid crystal layer is configured to present a planar texture state or a focal conic texture state in response to an action of an electric field, wherein the liquid crystal in the first liquid crystal layer presenting the planar texture state reflects second colored light with a color different from a color of the first colored light, while the liquid crystal in the first liquid crystal layer presenting the focal conic texture state transmits light,
wherein the first colored light and the second colored light are configured to be capable of being mixed into white light.
