1. A display device module, comprising:
a display panel, a non-coaxial optical component, a first optical element, and a second optical element, wherein the non-coaxial optical component comprises an incident surface and an emergent surface, and the incident surface of the non-coaxial optical component faces the display panel, so that light emitted by the display panel is capable of being transmitted through the incident surface and transmitted from the emergent surface;
the first optical element is configured to reflect, to the second optical element, the light transmitted from the emergent surface; and
the second optical element is configured to reflect, back to the first optical element, the light reflected by the first optical element, so that the light is transmitted from the first optical element.
