Further, two groups of collimating lens groups 230 can be fixed on the left waveguide plate 221 and the right waveguide plate 222 respectively, or the two groups of collimating lenses can be fixed on the left display screen 211 and the right display screen 212 respectively. Therefore, binocular imaging can be achieved by only adjusting the relative positions between the left display screen 211, the left waveguide plate 221, the right display screen 212, and the right waveguide plate 222. Simplifying the assembly process of binocular near-eye display devices.

Please continue to refer to Figure 1. The assembly system 100 according to the embodiment of the present invention includes an adjustment mechanism 10, a first camera 21, a second camera 22 and a reflector 30. The adjustment mechanism 10 is used to fix the left display screen 211 and/or the right display screen. 212, to adjust the position of the left display screen 211 and/or the right display screen 212; specifically, the adjustment mechanism 10 can be provided with an accommodation space, and the left display screen 211 and/or the right display screen 212 are arranged in the accommodation space, and It can be engaged with the adjustment mechanism 10 for fixation.

It can be understood that the adjustment mechanism 10 can only be engaged and fixed with the left display screen 211. At this time, the right display screen 212 can be fixedly arranged with the right waveguide plate 222. By adjusting the position of the left display screen 211, a binocular near-eye display device can be realized. When the image is combined, the adjustment structure can also be fixed only with the right display screen 212.

It should be noted that the light emitted from the left display screen 211 and the right display screen 212 is collimated into parallel light and then enters the left waveguide plate 221 and the right waveguide plate 222 respectively, and is transmitted through total reflection. Since total reflection does not change the transmission angle, Therefore, the light is still parallel light when coupled out from the left waveguide plate 221 and the right waveguide plate 222 . When the coupled parallel light is reflected by the reflector 30, the light can pass through the left waveguide plate 221 and the right waveguide plate 222 and be emitted to the side away from the light coupling out. This allows the first camera 21 and the second camera 22 to have a larger arrangement space, and when the first camera 21 and the second camera 22 are moved away, the combined image effect can also be confirmed through human eyes.

Further, the first camera 21 is used to receive the light coupled out of the left waveguide plate 221 reflected from the reflector 30 to form a first image, and the second camera 22 is used to receive the light reflected from the right waveguide plate 222 reflected from the reflector 30 Coupled light to form a second image; Understandably, the distance between the first camera 21 and the second camera 22 can be designed to be an adult's average interpupillary distance of 64 mm, and the first camera 21 and the second camera 22 can be commercially available.

The dotted line part in Figure 2 shows the transmission path of light and the arrangement positions of the first camera and the second camera when no reflector is set. It can be seen from the figure that when no reflector is set, due to Limited by the interpupillary distance of the human eye and the adjustment mechanism, when the interpupillary distance meets the normal interpupillary distance of the human eye, since the adjustment mechanism occupies a certain position, it is difficult for the operator to insert his head into the assembly system for observation. After the interpupillary distance of the display device is increased, the human head can normally enter the device to observe dust spots, etc. However, because the interpupillary distance is too large, it is impossible to subjectively detect the imaging effect.

After the waveguide plate 221 and the right waveguide plate 222 are received by the first camera 21 and the second camera 22, the position freedom of each component in the assembly system 100 is higher. At the same time, the first camera can be adjusted by adjusting the angle of the reflector 30. The positions of the camera 21 and the second camera 22 make it easier for the operator to directly observe the imaging effect of the binocular near-eye display device without being restricted by the structure of the assembly system 100, thereby further improving the imaging effect of the binocular near-eye display device. , improving the assembly effect of the assembly system 100 on the binocular near-eye display device.

Please continue to refer to FIGS. 1 and 2 . In some embodiments, the reflector 30 is arranged parallel to the left waveguide plate 221 and the right waveguide plate 222 . It can be understood that arranging the reflector 30 parallel to the left waveguide plate 221 and the right waveguide plate 222 can better control the direction of the reflected light, thereby facilitating the positional arrangement of the first camera 21 and the second camera 22 and making the operation easier. It is easier for personnel to directly observe the imaging effect of the binocular near-eye display device without being restricted by the structure of the assembly system 100 , thereby further improving the imaging effect of the binocular near-eye display device.
