Head-wearing virtual reality three-dimensional display device based on optical field imaging

Abstract

A head-wearing virtual reality three-dimensional display device based on optical field imaging comprises a head-wearing housing and a driving circuit board, a TFT liquid crystal display and an ocular lens configured to amplify a video image which are embedded in the housing in order. The TFT liquid crystal display comprises a liquid crystal display module and a backlight board, the liquid crystal display module and the ocular lens are located on the same optical axis, the liquid crystal display module comprises a first liquid crystal display screen and a second liquid crystal display screen formed by a liquid crystal layer and a thin film transistor, and a support piece configured for separation is arranged between the two liquid crystal display screens; and the first liquid crystal display screen, being closer to the ocular lens, performs display and forms a first virtual image, the second liquid crystal display screen performs display and forms a second virtual image, and the image distance of the first virtual image is shorter than the image distance of the second virtual image. The problems can be eliminated that users feel dizzy, nausea and visual fatigue in the usage process, and the head-wearing virtual reality three-dimensional display device based on optical field imaging can show a 4D immersion virtual reality scene with more real, three-dimensional and depth-of-field experience for users.

Description

technical field [0001] The present invention relates to the field of virtual reality display devices, and in particular to a head-mounted virtual reality stereoscopic display device based on light field imaging. Background technique [0002] Computing devices refer to other electronic devices that can access the Internet, such as personal computers, laptops, tablets, smartphones, etc. With the rapid development of processor chips and sensor chips for computing devices, people are more interested in the information generated by the fusion of electronic products and the augmented reality of users' perception of the physical world, which has gradually spawned some electronic products based on fusion technology. Or equipment research and development and technological evolution. Computing devices, especially electronic products represented by wearable devices, are becoming more and more popular in all aspects of modern life. [0003] The user augments the reality experience by ...

Problems solved by technology

[0004] At present, the display screen of the traditional HMD is single and fixed, that is to say, the object distance is fixed, so the focus of the human eye will not change when the user watches the image, and the human eye will soon feel visual fatigue , and the parallax of the displayed content will make the convergence distance of the eyes constantly change. This fixed display focus distance and the binocular convergence distance that changes at any time will cause the two kinds of nerve-connected movements to be forcibly separated, resulting in "focus disorder ” or “Vergence-accommodation conflict,” which leads to confusion in the brain
