Optionally, the lens located at the outermost side may be fixed by dispensing or by pressing a ring lock.
Here, the plurality of lenses may be arranged according to the diameter of the lenses, and the diameters of the lenses are sequentially reduced from the inside of the accommodating groove to the first opening.
In some embodiments, the near-eye display device further comprises a camera assembly disposed within the temple 20.
According to this disclosed embodiment, can set up the holding tank that is used for holding imaging components on picture frame or the mirror leg of near-to-eye display device, like this, regard near-to-eye display device's casing as imaging components's carrier, need not set up special casing for imaging components, can reduce the space that imaging components occupy, alleviate near-to-eye display device's weight, and then promote user's the experience of wearing. And, it contributes to the design of the near-eye display device with lightness and miniaturization.
Furthermore, the optical waveguide sets up on the picture frame to set up at the first opening part of holding tank and turn to the subassembly, so that the light that the formation of image subassembly output is followed first opening outgoing and is transmitted to the incoupling district of optical waveguide after turning to the subassembly deflection, like this, can set up the direction of arranging of formation of image subassembly according to actual need, with the thickness that reduces the picture frame, and then alleviate nearly eye display device's weight.
