Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] see figure 1 , is a schematic structural view of the combined optical magnifying mirror of the embodiment of the present invention. The combined optical magnifying mirror of this embodiment includes two parts, a central area A and an edge area B. The inner diameter of the edge area B closely matches the outer diameter of the central area A. The central area A is a convex lens (single-convex or double-convex) or a combined convex lens, and the convex lens is ...

Abstract

The invention discloses an optical magnification combined lens applied to head-wearing virtual reality display equipment. The optical magnification combined lens comprises a center central region and an edge region, the central region is a convex lens or a combined convex lens, the edge region is a Fresnel lens having a cambered surface substance recessed to a human's eye, the central region corresponds to main view field imaging, and the edge region correspond to edge view field imaging. Correspondingly, the invention further discloses the head-wearing virtual reality display equipment applying the combined lens. Through adoption of combination of the traditional lens and the Fresnel lens having the cambered surface substance, center image quality can be guaranteed, and a human eye's edge visual field is also expanded at the same time.

Description

technical field [0001] The invention relates to the field of optics, in particular to an optical magnifying combination mirror applied to a head-mounted display device, and a head-mounted virtual reality display device equipped with the optical magnifying combination mirror. Background technique [0002] At present, the optical magnification elements of head-mounted virtual reality display systems all use traditional lenses, such as spherical lenses, aspheric lenses or free-form optical lenses. Due to the limitations of optical processing technology and optical materials, the caliber of the optical magnifier group in the display system is usually It will be made relatively small (if the aperture is enlarged, the weight and volume of the optical system will increase significantly), the field of view that the user can observe through the optical magnifying glass group is limited by the diameter of the magnifying glass group, and the field of view of the magnifying glass group i...
