Claim 0:
1. A display module, comprising a display panel, a light grating assembly disposed on a side of the display panel, and a first polarizer disposed between the display panel and the light grating assembly;
wherein the light grating assembly comprises a plurality of first regions and a plurality of second regions alternately disposed, one of the second regions is disposed between adjacent two of the first regions;
wherein the light grating assembly further comprises:
a first substrate;
a second substrate disposed opposite to the first substrate; and
a liquid crystal layer disposed between the first substrate and the second substrate, and comprising first liquid crystal molecules and first dye molecules distributed in the first regions and second liquid crystal molecules and second dye molecules distributed in the second regions;

wherein the display module switches between a first mode and a second mode, under the first mode, a light transmission axis direction of the first dye molecules, a light transmission axis direction of the second dye molecules are parallel to a light transmission axis direction of the first polarizer to make light pass through the first regions and the second regions; under the second mode, a light transmission axis direction of the first dye molecules is parallel to the light transmission axis direction of the first polarizer, a light absorbing axis direction of the second dye molecules is parallel to the light transmission axis direction of the first polarizer to make an amount of light passing through the first regions greater than an amount of light passing through the second regions.
