Embodiment Construction

[0101] 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.

[0102] see figure 1 and figure 2 , figure 1 It is a diagram of the structure of the human eye. The human eye is approximately spherical, and the eyeball includes an iris 101 , a cornea 102 , a lens 103 , a retina 104 , and a macula 105 ;

[0103] The tissues of the eyeball 1 with optical imaging function are the cornea 102 and the lens 103 . The retina 104, located at the back of the eye, is the first stop for the transmission of neural information that forms ...

Abstract

The invention discloses a head-mounted three-dimensional display device which comprises an image generating device and a visual lens corresponding to an eye. A nanostructure functional film with a converging imaging function is arranged on at least one layer of the visible lens, so that the visible lens becomes a directivity function lens with a light field conversion function. The nanostructure on the directivity function lens matches an image output by the image generating device. A converging wave surface is projected in front of the human eye to form a virtual scene, or the converging wave surface and the wave surface of the reality scene are overlaid to acquire the fusion of real world information and virtual world information. According to the invention, a view angle image is converged in the space in front of the eyeball to form a virtual scene, which is consistent with the principle of the real scene imaging in the human eye; and visual fatigue caused by observing for a long time is greatly reduced compared with a traditional three-dimensional display technology.

Description

technical field [0001] The invention belongs to the field of three-dimensional image display, and in particular relates to a head-mounted three-dimensional display device. Background technique [0002] Virtual reality (VR) is an interactive three-dimensional dynamic visual simulation of multi-source information fusion, which immerses users into the environment. Virtual reality is a combination of multiple technologies. Among them, the wide-angle (wide field of view) stereoscopic display technology is a prerequisite for the user's immersive experience, and it is also a technical difficulty of virtual reality. In the VR display system, binocular vision is the basis of stereoscopic display, that is, different images are acquired through the left and right eyes, and are fused into stereoscopic images by the brain. However, in order to achieve a comfortable three-dimensional dynamic view, the clarity of the image obtained by both eyes, and the single eye adjusting the focus on ...
