Abstract: The invention discloses an optical system of near-eye see-through head-mounted display, comprising a first lens, a second lens and a micro image display, the first lens and the second lens are attached to the micro image display, and the first lens and the second lens are free-form lenses with a uniform thickness. The architecture of the optical system of near-eye see-through head-mounted display provided by the present invention can not only reduce the number of times the light is refracted in the architecture of the optical system, but also eliminate the aberration of the light emitted by the micro image display in all directions, making the images be viewed from all directions and angles with no aberration.

Abstract: The present disclosure relates to a swing bearing and a wearable device. The swing bearing includes an inner ring, an outer ring, and a plurality of rolling elements, a plurality of first grooves arranged at intervals along a circumferential direction being formed on an outer circumferential surface of the inner ring, a plurality of second grooves arranged at intervals along a circumferential direction being formed on an inner circumferential surface of the outer ring, each rolling element being disposed between the corresponding first groove and the second groove, and the rolling element, the first groove, and the second groove being configured to restrict relative rotational movement between the inner ring and the outer ring and allow the inner ring and the outer ring to produce shaft axis deflection movement.

Abstract: A head worn displaying device of the disclosure includes an optical reflective lens, a display screen and a cover. The optical lens and the display screen are mounted under the cover, and the cover may be similar to a hat tongue located ahead of the forehead of a user. The display screen can be integrated in a mobile phone, and a holder such as a clamper set is used to clamp the mobile phone. The angle of the optical lens can be adjusted, for example, by using a sliding groove and a magnetic hinge which are located at a front end of the hat tongue. The magnetic hinge slides in the sliding groove to adjust a distance between the display screen and the optical lens.
