Problems solved by technology

However, the field of view provided by the traditional VR lens is too small due to the limitation of the eye distance.
Even if the man-machine design is ignored and the eye distance is forcibly reduced to increase the viewing angle, there are still problems of single-lens aberration and serious distortion, which will affect the experience effect
[0003] Therefore, the single-lens VR optical path structure is limited by the curvature and thickness of the lens, and it is difficult to meet the effect requirements of the comprehensive field of view of both eyes exceeding 120°.

Embodiment 1

[0054] This embodiment provides a VR lens structure, including: a first lens and a second lens oppositely arranged; wherein, the first lens has a first side and a second side oppositely arranged, and the first side and the second side At least one of them is an aspheric surface; the second lens is a Fresnel lens, which has a Fresnel surface and a light surface oppositely arranged, and the light surface of the second lens is arranged opposite to the second side of the first lens, and the second The Fresnel surface of the lens is arranged away from the second side with a smoother surface.

[0055] Since the VR lens structure in this embodiment is composed of two lenses, that is, the first lens and the second lens, the VR lens structure is applied to the display system, and the VR lens structure has four optically effective surfaces, namely the first lens and the second lens. The first side, the second side of a lens, and the Fresnel surface and optical surface of the second lens...

Embodiment 2

[0060] This embodiment provides a VR lens structure and a display system using the VR lens structure. Wherein, the VR lens structure includes a first lens 1 and a second lens 2 oppositely arranged; as figure 1 As shown, the first lens 1 is an aspherical lens, that is, the first side S1 and the second side S2 of the first lens 1 are both aspherical; wherein, the first side S1 is called the first aspheric surface, and the second side S1 The side S2 is called the second aspheric surface; and the middle area of ​​the first aspheric surface protrudes toward the direction away from the second aspheric surface, and the edge area protrudes toward the direction close to the second aspheric surface; the second aspheric surface faces away from the first aspherical surface. The direction of the aspheric surface is convex. The second lens 2 is a Fresnel lens, and the optical surface S4 of the second lens 2 is aspherical and protrudes toward a direction away from the Fresnel surface S3.

Abstract

The invention provides a virtual reality (VR) lens structure and a display system, and belongs to the field of display technology. The VR lens structure comprises a first lens and a second lens whichare arranged oppositely, wherein the first lens has a first side face and a second side face which are arranged oppositely; at least one of the first side face and the second side face is a non-spherical face; the second lens is a Fresnel lens; the shiny side of the second lens is arranged opposite to the second side face; and relative to the shiny side, a Fresnel side is arranged far away from the second side face. The VR lens structure provided by the invention consists of two lenses, so that the VR lens structure has four optical effective surfaces when being applied to the display system.Accordingly, during design of the VR lens structure, the four optical effective surfaces can be analyzed and matched, so that the formed VR lens structure has a relatively large view angle, a better structure and better user experience when being applied to the display system.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a VR lens structure and a display system. Background technique [0002] In VR display devices, in order to obtain a better visual experience, one design method is to increase the visual field of view and increase the sense of immersion. However, the field of view provided by the traditional VR lens is too small due to the limitation of the eye distance. Even if the man-machine design is ignored and the eye distance is forcibly reduced to increase the viewing angle, there are still problems of single-lens aberration and serious distortion, which will affect the experience effect. [0003] Therefore, the single-lens VR optical path structure is limited by the curvature and thickness of the lens, and it is difficult to meet the effect requirements of the binocular comprehensive field of view exceeding 120°. [0004] In order to improve the large viewing angle imaging ...
