Abstract
Disclosed is a total reflection based compact near-eye display device with a large field of view. Light rays emitted by an image source (103) are transmitted by using a total reflection prism (101), and are finally subjected to image magnification by means of a near-eye dioptric component (105), such that a near-eye display effect with a large field of view is achieved under the conditions of a compact volume. A gap layer exists between the near-eye dioptric component and the total reflection prism, and the gap layer contains substances with a refractive index lower than that of the total reflection prism.
Claims20
A compact near-eye display device with a large field of view angle based on total reflection, comprising:
- a total reflection prism for totally reflecting and conducting light emitted by an image source for one or more times;
- and
- a near-eye dioptric component for enlarging the image after one or more reflections of the light, wherein a gap layer exists between the near-eye dioptric component and the total reflection prism, and the gap layer contains substances with a refractive index lower than that of the total reflection prism.
