For head-mounted devices, near-eye display is the key to its technology, and imaging quality and thinness are major considerations. The near-to-eye display system generally consists of an image far-near light transmission system, and image pictures sent by an image source are transmitted to human eyes through an optical transmission system.

Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
Referring first to fig. 1 and 5, two embodiments of waveguide assembly of the present application are shown. The waveguide sheet assembly 100 of the present embodiment includes a left waveguide sheet 11 and a right waveguide sheet 12 corresponding to the left eye and the right eye, respectively. Therefore, the two waveguide sheets take the joint as the center, the structures are in mirror symmetry, and in order to ensure the uniformity of light irradiation, the left and right waveguide sheets are made of the same material.
The two waveguide pieces comprise an entrance pupil grating unit, an expansion pupil grating unit and an exit pupil grating unit, input light is transmitted into the entrance pupil grating unit, light rays pass through the expansion pupil grating unit to realize transverse expansion pupil, and then the exit pupil grating unit realizes longitudinal expansion pupil and guides the light rays out of the eye. Specifically, the entrance pupil grating unit is disposed near the joint, the pupil expansion grating unit is disposed on one side of the entrance pupil grating unit away from the joint in the horizontal direction, and the exit pupil grating unit is disposed below the pupil expansion grating unit.
The left waveguide plate 11 in this embodiment includes a left entrance pupil grating unit 1a, a left pupil expansion grating unit 2a, and a left exit pupil grating unit 3 a; the right waveguide 12 includes a right entrance pupil grating unit 1b, a right pupil grating unit 2b, and a right exit pupil grating unit 3 b.
The connecting position of the two waveguide pieces forms an obtuse angle, so that the waveguide piece assembly 100 can be more attached to a human face when being applied to glasses, and the wearing comfort level is improved; the obtuse angle in the embodiment is more than or equal to 120 degrees, and is more suitable for human faces. And the left and right waveguide sheets have included angles, and the entrance pupil area is divided into left and right separated entrance pupil grating units, so that the crosstalk phenomenon of light waves on the left and right sides is greatly reduced.
If the inner obtuse angle is used as the inner side of the waveguide assembly 100 and the outer obtuse angle is used as the outer side of the waveguide assembly 100, in this embodiment, the input light is input from the outer side of the waveguide assembly 100 and enters the waveguide assembly 100 in a transmission manner, so that the direction of the emergent light of the exit pupil grating unit can be ensured to be consistent with the direction of the incident light of the entrance pupil grating unit. In this embodiment, the entrance pupil grating unit, the pupil expanding grating unit, and the exit pupil grating unit are all surface relief gratings or volume holographic gratings.
To realize the folding connection of the left and right waveguide pieces, the two waveguide pieces may be an integral structure, and the integral structure is bent to form the waveguide piece assembly 100 of the present embodiment, as shown in fig. 1. Specifically, a butterfly waveguide sheet can be used for bending. The angle of the left and right waveguide pieces is fixed, so that the wearing stability can be ensured.
The left waveguide plate and the right waveguide plate can be independent two pieces, and can be fixedly connected, for example, the left waveguide plate and the right waveguide plate are connected through fixing glue, and the angles of the two waveguide plates are fixed. And may be connected by a rotating shaft 13 as shown in fig. 5. When the rotating shaft 13 is used for connection, the angles of the two waveguide pieces can be adjusted, so that the face of a wearer can be customized and used. For more convenience of use, the rotation shaft 13 may be configured such that the left and right waveguide pieces can be folded only at the inner side of the waveguide piece assembly, and further, may be configured such that the folding degree of the left and right waveguide pieces is limited to achieve an obtuse angle of between 120 degrees and 180 degrees.
The folded waveguide sheet assembly 100 of the present application can achieve normal display because input light is injected from the outside of the waveguide sheet assembly 100, and the waveguide sheet assembly of the present application can ensure the consistency of the optical path direction, as can be seen in fig. 2 to 4.
The waveguide plate is used for translating the light beam and transferring the light beam from an entrance pupil position to an exit pupil position, and the waveguide plate follows the reflection and transmission principle of the light. As shown in fig. 2-3, input light enters the waveguide plate by transmission coupling, the direction of the output light is the same as that of the input light, and the direction of the light path is not affected by the folding angle of the waveguide plate. In the application corresponding to the AR glasses, as long as the input light transmitted into the waveguide sheet is perpendicular to the eyes of the human, no matter what angle the waveguide sheet is, the light output to the eyes of the human can enter the eyes of the human vertically.
Accordingly, in fig. 4, the input light is coupled into the waveguide plate by reflection, and the optical path direction is affected by the folding angle of the waveguide plate. If the input light is perpendicular to the human eye, the waveguide plates must be parallel to ensure that the output light enters the human eye perpendicularly.
In summary, in the present application, for the waveguide sheet assembly in the folded shape, the input light transmission coupling mode is adopted to achieve normal display.
The present application also proposes an opto-mechanical front folded AR eyepiece, i.e. the above waveguide assembly is applied in an AR eyepiece, as shown in fig. 6-8. The folded AR eyepiece 300 in front of the optical engine includes the waveguide assembly 100 described above and a single projection optical engine 5.
The single projector 5 is disposed outside the waveguide assembly 100 and faces the entrance pupil grating unit, that is, the single projector 5 is disposed symmetrically with respect to the middle line of the obtuse angle in the waveguide assembly 100, and the projection direction of the single projector 5 is parallel to the middle line of the obtuse angle in the waveguide assembly 100, that is, the projection direction of the single projector 5 is perpendicular to human eyes. As can be seen from the above analysis, regardless of the degree of folding of the waveguide assembly 100, the light finally output from the waveguide assembly 100 also vertically enters the human eye.
The single optical projector 5 is also symmetrically arranged with the middle branch as the center, and can ensure that the left and right waveguide pieces input the same projection light. Obviously, if the single projector is disposed inside the waveguide assembly, reflective coupling is adopted, and for the left and right folded waveguides, a single projector that inputs light perpendicularly to the left and right waveguides is required to be disposed, and the structure of the AR eyepiece is more complicated.
The left waveguide piece and the right waveguide piece of the waveguide piece assembly are spliced at a certain angle and can be applied to AR glasses to be more attached to a human face. And the light rays emitted from the outer side of the waveguide assembly can be emitted in the same direction after passing through the entrance pupil grating unit, the expanding pupil grating unit and the exit pupil grating unit, so that the light rays can be directly emitted into human eyes, and an included angle cannot be generated due to the folding of the waveguide assembly. The using effect of the AR glasses is ensured.
