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:

• a total reflection prism for totally reflecting and conducting light emitted by an image source for one or more times,
• a near-eye refractive component for enlarging the image after one or more reflections of the light,
• wherein the near-to-eye refractive component allows external light to pass through without diopter, and the secondary reflection surface is semi-reflective, so that a human eye can see external environment through the near-to-eye refractive component and the total reflection prism while seeing the displayed image clearly, thus realizing the semi-transparent display effect of augmented reality,
• wherein the total reflection prism comprises a compensation surface, and the compensation surface is a curved surface and is located on a side of the total reflection prism facing away from the near-to-eye refractive component, and the refractive surface of the near-to-eye refractive component is matched to perform refractive adjustment on internal display light and external environmental light,
• when the diopters of the compensation surface and the refractive outer refractive surface are combined differently, it can adapt to users with different eyesight,
• wherein the compensation surface extends close to the image source, thereby further reducing the projection of the opaque surface, forming a smaller view blocking area, and forming a better “narrow frame” effect.
