Wearable AR system, AR display device and its projection source module

An augmented reality display device comprising:

• a projection source module and an optical path module, wherein the projection source module comprises a projection source and a fiber optic panel integrated on the projection source, the fiber optic panel defines a light outgoing surface, and the optical path module comprises a beamsplitter and a reflector,
• wherein the fiber optic panel comprises optical fibers having a wire diameter smaller than a size of pixels of the projection source so that each pixel of the projection source corresponds to a plurality of optical fibers, and
• wherein virtual image light projected out of the projection source module is incident on the beamsplitter, reflected by the beamsplitter onto the reflector, reflected by the reflector, and then transmitted through the beamsplitter, entering a human eye eventually.

An augmented reality display device comprising

• a projection source module and an optical path module, wherein the projection source module comprises a projection source, the optical path module comprises a beamsplitter and a reflector, and the reflector comprises an antireflection film, a refractive correction substrate and a semi-transflective film,
• wherein the virtual image light projected out of the projection source module is incident on the beamsplitter, reflected by the beamsplitter onto the reflector, reflected by the reflector, and then transmitted through the beamsplitter, entering a human eye eventually, and
• wherein, when incident on the reflector, the virtual image light is first incident on the antireflection film and then incident on the refractive correction substrate and finally incident on the semi-transflective film and reflected by the semi-transflective film, or the virtual image light is first incident on the semi-transflective film when incident on the reflector.
