A near-eye display system (1) and AR glasses (3). The near-eye display system (1) comprises an optical waveguide module (10), an optical engine module (20), and a metalens assembly (22). A first coupling-in grating region (111) and a first coupling-out grating region (112) are formed in the optical waveguide module (10). The optical engine module (20) comprises a light source assembly (21) disposed opposite the first coupling-in grating region (111), and the metalens assembly (22) disposed between the light source assembly (21) and the optical waveguide module (10), wherein the light source assembly (21) is used for outputting an image optical signal to the metalens assembly (22). The metalens assembly (22) comprises a substrate (221) and a metasurface structure (222) on the substrate (221), the metasurface structure (222) configured to receive the image optical signal and diffract the optical signal to the first coupling-in grating region (111).

The present application belongs to the technical field of glasses, and relates to a pair of smart glasses. The smart glasses comprise a frame, an imaging optical module, an eye-tracking optical module and an waveguide assembly, wherein the frame comprises rims and a connecting part disposed on one side of each rim, a mounting cavity for the mounting of the imaging optical module and the eye-tracking optical module thereon being formed in the connecting part; and the waveguide assembly is embedded in the rims, and comprises a waveguide substrate, and a first coupling-in and coupling-out grating group and a second coupling-in and coupling-out grating group, which are disposed on the waveguide substrate, at least some gratings in the first coupling-in and coupling-out grating group and the second coupling-in and coupling-out grating group being located on the same side of the waveguide substrate, and the gratings located on the same side of the waveguide substrate, namely, a first periodic grating and a second periodic grating, at least partially overlapping to form a composite grating. The smart glasses in the present application can independently couple in or out light rays of corresponding wavebands in the same region on the same side of a waveguide substrate by means of gratings of a composite grating, and thus effectively reduce the absolute area of the gratings, thereby facilitating a lightweight design and improving long-term wearing comfort.

An optical waveguide plate (100), a frame, and smart glasses, which relate to the technical field of smart glasses. The optical waveguide plate (100) includes a waveguide substrate (10), a coupled-in region (20), and a coupled-out region (30); where the coupled-in region (20) and the coupled-out region (30) are disposed on the waveguide substrate (10), the coupled-in region (20) is configured to couple light into the waveguide substrate (10), and the coupled-out region (30) is configured to couple out the light propagating within the waveguide substrate (10); and a bottom edge of the coupled-out region (30) is located above a horizontal bisector of the optical waveguide plate (100), or the bottom edge of the coupled-out region (30) is entirely or partially flush with the horizontal bisector of the optical waveguide plate (100). The problem that smart glasses are unsuitable for extended use by a user due to the occurrence of rainbow patterns on the smart glasses is solved.
