Problems solved by technology

Currently, the head-mounted displays on the market are not big enough, the virtual display screen is small, and the virtual display effect has image quality problems such as chromatic aberration and distortion. It is also the difficulty of existing technologies, and it is even more difficult to combine these technologies

Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] The control module can be connected to the 3D head-mounted display through USB2.0 or USB3.0, or connected to the 3D head-mounted display through a wireless transmission module. The wireless module can be infrared, bluetooth, wifi, etc., such as Huawei's MW269 wireless wifi module . Turn on the head-mounted display, select the image display component of the head-mounted display to read video mode, and start to read the video information in the memory card in the control module. The video can be an ordinary two-dimensional video. At this time, the two liquid crystal displays display the same picture, and the viewer feels the two-dimensional video. When the film source is a 3D format film, you can adjust the controller to drive the liquid crystal so that the two liquid crystal displays display the same set of pictures but different pictures, and the human ...

Abstract

The invention provides a three-dimensional (3D) head-mounted display. The 3D head-mounted display comprises an image displaying component, an optical imaging system, an optical adjustment component, an audio transmission component, a camera module, a control module and an eyeglass type casing. The 3D head-mounted display is characterized in that the control module is respectively connected with the image displaying system, the audio transmission component and the camera module; the optical adjustment component is connected with the optical imaging system; the relative position of optical glasses of the optical imaging system can be adjusted through the optical adjustment component; and the camera module is connected with the image displaying component through wired connection. The 3D head-mounted display can be suitable for human engineering to a maximum measure, can protect the eyes from being fatigued, and can be used for displaying 3D stereoscopic video and common 2D video and be suitable for more people; and through the switchable performance of the camera module, the 3D head-mounted display is more humanized, and can prevent users from feeling panic caused by confining for a long time.

Description

Technical field [0001] The present invention belongs to the field of engineering optics, and specifically relates to a 3D head-mounted display, specifically a head-mounted display that can play 3D stereoscopic video. Background technique [0002] Nowadays, the display technology has become more and more mature. Microdisplays can be made very small, large displays can be made very light, and naked-eye 3D technology is becoming more and more mature. However, it is difficult to concentrate these advantages in one, that is, it requires a portable display device to experience the 3D effect of a large screen. Some head-mounted displays are currently on the market, but there are many technical deficiencies. At present, the head-mounted displays on the market are not big enough, the virtual display screen is small, the virtual display effect has image quality problems such as chromatic aberration and distortion, the system is inconvenient to adjust the diopter and interpupillary distanc...
