Classification: CPC G  B | IPC B  G

Claim 0:
1. A display apparatus, comprising a projector device, a reflector structure and a light beam diffuser structure,
wherein light emitted from the projector device passes through the light beam diffuser structure, is reflected by the reflector structure, and then reaches a first predetermined region;
the light beam diffuser structure is configured to diffuse a light beam passing through the light beam diffuser structure without changing chief light of the light beam;
the reflector structure comprises a plurality of sub-reflector structures, the plurality of sub-reflector structures are configured to reflect the light emitted from the projector device and the light reflected by the plurality of sub-reflector structures reaches a second predetermined region within the first predetermined region if the light beam diffuser structure is removed from an optical path from the projector device to the first predetermined region, and an area of the second predetermined region is smaller than an area of the first predetermined region;
the reflector structure further comprises a substrate, the plurality of sub-reflector structures are arranged at intervals on a side of the substrate, the side of the substrate faces the projector device, each of the plurality of sub-reflector structures comprises at least one reflective surface, and a plurality of reflective surfaces that the plurality of sub-reflector structures comprise are configured to reflect and converge the light emitted from the projector device;
each of the plurality of sub-reflector structures comprises one planar reflective surface, the reflector structure comprises a reference region, and angles between planar reflective surfaces of the plurality of sub-reflector structures and the substrate are gradually increased along a direction away from the reference region.
