1. A display assembly, comprising:
a display module comprising a plurality of pixel islands arranged in an array form; and
a plurality of lens arrays laminated one on another at a light-exiting side of the display module,
wherein each lens array of the plurality of lens arrays comprises a substrate, a cover plate arranged opposite to the substrate, a first transparent electrode arranged at a side of the substrate facing the cover plate, a second transparent electrode arranged at a side of the cover plate facing the substrate, and a liquid crystal layer and a diffraction lens grating arranged between the first transparent electrode and the second transparent electrode;
the diffraction lens grating comprises a plurality of diffraction lens grating units corresponding to the plurality of pixel islands respectively; and
a voltage is applied to each of the first transparent electrode and the second transparent electrode in such a manner that a refractive index of a liquid crystal molecule in the liquid crystal layer is equal to or not equal to a refractive index of the diffraction lens grating,
wherein the quantity of the plurality of lens arrays laminated one on another is greater than 2, with respect to two adjacent lens arrays in the plurality of lens arrays, the substrate of a lens array distal to the display module in the two adjacent lens arrays is reused as the cover plate of another lens array proximal to the display module in the two adjacent lens arrays.
