Abstract: Disclosed is a thin near-to-eye display device with a large field of view angle. Two or more radial reflection units are adopted to be arranged in front of human eyes, and a large-area image is projected and formed on the retina of the human eyes, so that a near-to-eye display effect of the large field of view angle is achieved in a thin volume.

Abstract: The present invention discloses a thin type large field of view near-eye display device, which comprises two or more radial reflection units, which are arranged in front of human eyes to generate two or more sub-images and spliced into a larger image on the retina of human eyes, so as to realize a near-eye display effect with a large field of view in a thinner volume; the radial reflection units comprise a light source, a reflecting surface, a transmissive dioptric apparatus and/or a reflective optical component, and the present invention relates to the technical field of near-eye display devices. The thin type large field of view near-eye display device realizes the nesting of images with various definitions by adopting different areas of the same screen, and is widely used as a low-cost display solution to improve the definition of the central area.

Abstract: A near-eye display includes a human eye-oriented display screen, a microlens array located on the side of the display screen close to human eyes, and an image adjustment unit. The display screen has multiple display regions that are separate from each other. Each display region correspondingly displays a subimage, and the subimages displayed on the display regions combine a complete, gap-free and overlap-free image presented to a user. The microlens array focuses the image displayed on the display screen into a near-eye image that can be clearly seen by human eyes, each microlens being corresponding to one of the display region. The image adjustment unit adjusts in real time a displayed image size of each display region according to a visual acuity state of the user and/or the image adjustment unit moves in real time the position of each display region according to a gaze direction of the user.

Abstract: A spatial focal field type glasses display product can present virtual images at different distances simultaneously. The product is a frame type glasses or corneal contact lens and comprises a projection component and a display control device. The projection component comprises a plurality of projection units, each projection unit projects a plurality of elementary beams. The elementary beams projected by the same projection unit diverge and do not intercept with each other. The elementary beams projected by different projection units intersect near the retina after passing through the crystalline lens. The intersection point is a cluster focus. All cluster focuses form a spatial focal field which envelop the retina. When the diopter of the crystalline lens changes, the spatial focal field displaces and deforms accordingly, so different cluster focuses fall on the retina to be seen clearly, while the other cluster focuses tend to disperse and cannot be seen clearly.
