Augmented reality display device with monocular stereo display function and display method of augmented reality display device

Abstract

The invention discloses an augmented reality display device with a monocular stereo display function and a method of the augmented reality display device. The device comprises a shell, wherein a microdisplay, a liquid lens, a beam splitting flat plate of which one face is coated with beam splitting film and a polarizing assembly are arranged on the shell; the micro display is used for displayinga two-dimensional image; the face, coated with the beam splitting film, of the beam splitting flat plate is obliquely arranged facing a display face of the micro display and used for receiving and reflecting the two-dimensional image; the liquid lens is used for magnifying the two-dimensional image and imaging the two-dimensional image at a certain distance; the polarizing assembly comprises polarizing film I, a liquid crystal cell and polarizing film II which are overlaid in sequence, and the direction of the transmitting axis of the polarizing film I is perpendicular to the direction of thetransmitting axis of the polarizing film II. The augmented reality display device with the monocular stereo display function has the advantages that according to the combination of the conditions whether or not the liquid lens has focal power, whether or not the micro display performs display and whether or not light transmission occurs on the polarizing assembly, it is achieved that a virtual scene displayed by the micro display and a scene of the actual environment are projected into the human eye alternately, so that the display mode of a stereo scene is improved, and the clear display of the stereo scene is achieved.

Description

technical field [0001] The invention relates to the field of optical display technology, in particular to an augmented reality display device and display method capable of monocular stereoscopic display. Background technique [0002] Augmented Reality (Augmented Reality, AR) is a technology that combines the real world with virtual display, which can superimpose virtual information on the real world, and has a wide range of applications in various industries. At present, when the head-mounted display device used for augmented reality displays images, the monocular can only perform two-dimensional display, and the stereoscopic display needs to be realized by using binocular display images with a certain parallax, but the realization method of this stereoscopic display It will cause the binocular convergence conflict of the human eye, and wearing it for a long time will easily lead to discomfort such as dizziness.

Problems solved by technology

At present, when the head-mounted display device used for augmented reality displays images, the monocular can only perform two-dimensional display, and the stereoscopic display needs to be realized by using binocular display images with a certain parallax, but the realization method of this stereoscopic display It will cause the binocular convergence conflict of the human eye, and it will easily cause dizziness and other discomfort when worn for a long time

[0003] Although Magic Leap One, a product recently released by the US company Magic Leap, can display an image surface two distances away from the human eye (https: / / www.ifixit.com / Teardown / Magic+Leap+One+Teardown / 112245), there are The number of display depths is small and the display depth is discontinuous; some companies also use liquid lenses to achieve monocular stereoscopic display (patent number is CN201610770922-true three-dimensional holographic display head-mounted visual equipment), because the liquid lens in this display method is located In front of the eyes, it will cause the deformation of objects in the real world seen by people, and the optical penetration augmented reality display cannot be realized, and the depth image segmentation method of the stereoscopic scene cannot realize a clear three-dimensional display
