Total reflection based compact near-eye display device with large field of view

A compact near-eye display device with a large field of view angle based on total reflection, comprising:

• two sets of total reflection prisms and two image sources, wherein each of the two sets of total reflection prisms is configured for totally reflecting and conducting light emitted by a corresponding one of the two image sources for one or more times, and
• a near-eye refractive component for enlarging the image after one or more reflections of the light,
• wherein a gap layer exists between each of the two image sources and the near-eye refractive component and the total reflection prism, and the gap layer contains substances with a refractive index lower than that of the two sets of total reflection prisms, so that light is totally reflected and transmitted on an inner surface of each of the two sets of total reflection prisms,
• wherein the two sets of total reflection prisms and the two image sources are respectively placed in front of the human eyes, project light from different directions, and splice two displayed pictures to achieve a larger field of view angle display effect, and the two sets of total reflection prisms and the two image sources share a same set of the near-eye refractive component for enlarging images,
• wherein optical path isolation is arranged between the two sets of total reflection prisms in order to prevent crosstalk between the light of the two sets of total reflection prisms.
