Embodiment 1

[0077] Such as figure 2 As shown in , the above-mentioned curved surface component includes a curved surface 11;

[0078] The microdisplay 21 in the imaging device 2 is an active microdisplay, and the light source is included in the microdisplay 21;

[0079] Then the micro-display 21 interferes with the user's forehead 22 through the isolation material, and forms a first preset angle α with the user's forehead 22, and the display surface of the micro-display 21 is arranged facing the curved surface component;

[0080] A mechanical mount 23 is provided between the microdisplay 21 and the curved surface 11 for fixing the relative positions of the microdisplay 21 and the curved surface 11 .

[0081] Specifically, in this embodiment, the above-mentioned microdisplay 21 is an active type display such as an OLED display, so the microdisplay 21 is equipped with an illuminator as a light source. Such a design does not require an additional light source in the display device, so that...

Embodiment 2

[0086] Such as image 3 As shown, on the basis of the first embodiment above, the thickness of the above-mentioned curved surface 11 can be unevenly distributed in the xy coordinate space, that is, the outer surface 11b adopts a free-form surface form different from the inner surface 11a, so as to specially provide for people with myopia or hyperopia users with visual impairments. For example, in order to make the near-eye display system more suitable for users with visual impairment, a transflective polymer can be coated on the inner surface 11a of the above-mentioned curved surface 11 to be responsible for collimating and combining light, and on the outer surface of the above-mentioned curved surface 11 Some optical processing is performed on 11b to configure eyeglasses for visually impaired users, so that the thickness of the curved surface 11 changes as described above. After the optical processing, the inner surface 11a of the above-mentioned curved surface 11 needs to b...

Embodiment 3

[0088] Such as Figure 4 As shown, the above-mentioned curved surface component includes a curved surface 11;

[0089] The microdisplay 21 in the imaging device 2 is a passive microdisplay;

[0090] The light source is arranged in front of the eyes 12 of the user;

[0091] The microdisplay 21 is perpendicular to the light source 45 and arranged above the light source, and the display surface 41 of the microdisplay 21 is arranged toward the curved surface 11 in the curved surface assembly;

[0092] A polarizing beam splitter 42 is arranged between the light source and the microdisplay 21 .

[0093] Specifically, in this embodiment, the above-mentioned microdisplay 21 is a passive microdisplay, such as a liquid crystal display (Liquid Crystal Display, LCD), or a silicon-based liquid crystal display (Liquid Crystal on Silicon, LCOS), or a digital micromirror device (Digital Mirror Device, DMD), or a scanner of a micro-electromechanical system (Micro-electromechanical Systems, ...

Abstract

A near-eye display and a near-eye display device, related to the technical field of augmented reality imaging. The near-eye display system comprises a curved surface component, the curved surface component comprising at least one curved surface (11), an inner surface (11a) of the curved surface (11) being disposed facing an eye (12) of a user, an outer surface (11b) of the curved surface being disposed at a thickness distance from the inner surface (11a) along a major optical axis, and the inner surface (11a) being coated with a material which partially transmits light and partially reflects light; an imaging apparatus (2) disposed at a position near the eye (12) of the user; the imaging apparatus (2) further comprising a light source (45) and a micro-display device (21), the light source (45) being used to illuminate the micro-display device (21), and a light beam (3) emitted by the micro-display device being reflected by a curved surface (11) of the curved surface component and entering the eye (12) of the user; the curved surface (11) also being used to transmit an external light ray into the eye (12) of the user. The present invention maintains a compact and lightweight structure while increasing field of view of a near-eye display device, improving user viewing experience and aesthetics, and decreasing technical complexity and manufacturing costs of the display device.

Description

technical field [0001] The invention relates to the technical field of augmented reality imaging, in particular to a near-eye display system and a near-eye display. Background technique [0002] With the development of augmented reality (Augmented Reality, AR) technology, the market of portable devices and wearable devices applied to AR technology is also growing rapidly. Among many hardware implementations using AR technology, head-mounted displays (Helmet-Mounted Display, HMD) and near-eye displays (Near-to-Eye Display, NED) are the most effective and can bring users To achieve the best experience. [0003] The so-called head-mounted display (HMD), because its shape is similar to glasses, can also be called glasses-type display or video glasses. It can send optical signals to the eyes through various head-mounted display devices, so as to realize the difference in AR technology. display effect. [0004] The so-called near-eye display (NED) is a head-mounted display (HMD...
