Head-mounted virtual reality display device and automatic adjustment method

Abstract

The invention provides a head-mounted virtual reality display device and an automatic adjusting method. The head-mounted virtual reality display device comprises a first display screen, a second display screen, a first limiting element, a second limiting element, a first optical display module, a second optical display module, a camera module and a control module. The first optical display moduleand the second optical display module herein provide basically zero magnification for optical images passed through the first and second limiting elements, distortion degree of the optical images is decreased, and diffraction effect is weakened; the head-mounted virtual reality display device may automatically adapt to a user's pupil distance and its wearing condition, so that a virtual displayedimage viewed by the user through the first and second optical display modules has biggest gray-dark boundary, and the view angle has no evident decrease. The automatic adjusting method is applicable to the head-mounted virtual reality display device.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a head-mounted virtual reality display device and an automatic adjustment method. Background technique [0002] At present, the head-mounted virtual reality display device has two forms of adjustable and fixed virtual reality optical display modules in terms of the applicability of the interpupillary distance of different users. [0003] For the head-mounted virtual reality display device whose optical display module is adjustable, users can manually adjust the physical distance of the optical display module according to their own interpupillary distance to achieve an optimal virtual reality viewing experience. For the head-mounted virtual reality display device that needs to manually adjust the physical distance of the optical display module, it has the disadvantages of complex mechanical structure and troublesome adjustment. [0004] For a head-mounted virtual reality ...

Problems solved by technology

For the above problems, the current existing solutions are: reduce the effective imaging aperture of the lens, the disadvantage of this method is: in order to adapt to the fact that most users cannot observe the rectangular border of the display screen, the effective imaging aperture of the lens needs to be greatly reduced , this directly leads to a sharp reduction in the field of view of the virtual display, which reduces the immersion of the virtual reality experience and enhances the visual sense of the leopard in the tube

Since the boundary of the display screen is limited on the display screen, for any user, what they finally see is a virtual display screen with a near-circular border due to distortion after the circular border display screen passes through the optical display module. , although this method can solve the problem of special-shaped borders, however, since the light source emitted from the display screen will produce a certain diffraction effect on the border of the limiting sheet, the user can see that the border has the same color as the surrounding picture through the optical display module. An inconsistent color will also affect the visual experience of virtual reality
