[Prior Art] A head-mounted display (HMD) is a type of image display device that can be used to display images from televisions, digital versatile discs, computer applications, game consoles, or other similar applications. HMD can be monocular (view from a single eye to a single image), binocular (biocular) (from two eyes to a single image), or binocular ( binocular) (each eye sees a different image) monitor. In addition, the image of Hang Ying to (two) eyes can be viewed completely by the user, or superimposed on the user's field of vision to the outside world. For most HMD designs, considerations such as image resolution, distance of the virtual image from the eye, size of the virtual image (or angle of the virtual image), distortion of the virtual image, distance between the user's left and right pupils (distance between diaphragms (ipD)) ), Diopter correction, light loss in image splitting and transmission, power consumption, weight and price parameters. Ideally, _Single_ HMDT allows multiple users to take into account / find the number of images without displaying images, whether stereoscopic binocular images or simple monocular (m_sc〇pic) binocular images can be displayed . If the resolution of the picture on the internal display of the HMD is 800,600 pixels, the acceptable virtual image size produced by the HMD's optics is: approximately 1.5 m (52, 56 "formed at a distance of 2 m ) The diameter of the virtual image, which corresponds to a viewing angle of about 36. In order to better fit a person's head and eyes, ipD should be between 45 claws and less.

It should be clearly understood, however, that each of the drawings' is provided for the purpose of illustration and description only and is not intended as a definition of the scope of the invention. [Embodiment] O: \ 90 \ 90299 DOC-9-9200521559 Figure 1 illustrates a top view of a head-mounted device 100 that is not configured according to a specific embodiment of the present invention. The sub-image creation area 101 (in the device 100) creates a plurality of sub-images from a single image source. The display screen 110 may be any suitable device operable to display a visual image of the data by using an external illumination source, such as a liquid crystal display (LCD) screen. The display screen 11o is placed along a display axis 1 丨 1. In a specific embodiment, the surfaces of the display shaft 111 and the display screen 11o are exactly perpendicular to the user's face plane 17o. The display lens 115 is positioned such that f is along and perpendicular to the optical path 112 and has a display lens focal point 124. The display focal point 124 is located on the light path 112, and the area 10 is configured such that the display lens _ focus 124 is located inside the splitter 120. In a specific embodiment of the use area 10, the splitter 120 is a symmetrical V-mirror composed of the partially reflecting surface 12 1 on the right and the partially reflecting surface 122 on the left. The area 101 is configured such that the reflective surface 121 and the reflective surface 122 share a common side and are symmetrically disposed with respect to the display axis 111. Zone 101 can thus generate two completely complete and independent images of display 110 (referred to herein as sub-images), each image traveling along an independent optical path (referred to herein as a sub-path). φ includes a right light source 125 and a left light source 126 in the area 101, which are located in a line with the focus 12 of the display lens and are symmetrically arranged with respect to the display axis 1 丨. Light from the light sources 125 and 126 passes through the surfaces 121 and 122, is collimated by the display lens 115, and illuminates the display screen 110. In the specific embodiment of FIG. 1, the generated collimated light beam will be slightly inclined with respect to the optical axis 111. Display screen 11 〇 Illumination by the right light source 125 creates a display left-eye sub-image, which is focused by the lens 115 to illuminate the reflective surface 122, which reflects the left-eye display sub-image downward Redirect to sub-light path 14o. Similar to 0 \ 90 \ 90299 DOC -10- 200521559 ground, the display screen Π0 is illuminated by the left light source 丨 26, which creates a right-eye display sub-image, which is focused by the lens 115 to illuminate the reflective surface 121, and the reflective surface 丨 21 the right eye The display sub-image is redirected down to the sub-light path 1 3 0. The left-eye sub-image will travel along the sub-light path 14 and be guided to the user's left eye 146. The left-eye reflector 142 is placed along the sub-optical path 140, and the reflector is configured to change the left-eye sub-optical path 140 by 90. Direction and redirect it to the entire reflective surface in the left eyepiece optics 145. The right-eye sub-image will travel along the sub-light path 130 and be guided to the user's right eye 136. The right eye reflector 1 32 is placed along the sub-optical path 1 30, and the reflector is configured to change the right-eye sub-optical path 130 by 90. Direction and redirect it to the entire reflective surface in the right eyepiece optic η ;. The right eyepiece optical device 135 and the left eyepiece optical device 145 may be composed of a single lens or multiple lenses, and the lens is designed to appropriately enlarge the right eye sub-image and the left eye sub-image for the user's right eye. 3 (5 views And the user ’s left eye 146 to view. Some specific embodiments may use a diffuser on which a real image is created. The right and left eyepiece optics 35, 145 may then be used to magnify these images for the user to view. In order to obtain a larger viewing angle (such as 36.), these real images should be created behind the reflectors 132 and 142 and very close to the right and left eyepiece optics 135 and 145. The eyepiece optics 135 and 145 are adjustable single Lens, but other embodiments may use any configuration capable of appropriately magnifying the right-eye and left-eye sub-images for viewing by the right-eye 136 and the left-eye 146. In addition, although the reflector 132 of the device 100 is , 142 are depicted as mirrors, and surfaces 121, 122 are depicted as partially reflective surfaces, but specific embodiments are not limited to using mirrors or partially reflective surfaces to redirect a light path or sub-light path. Instead, Mirror, O: \ 90 \ 90299 DOC -11-200521559 polarized beam splitter or any other suitable configuration for redirecting an optical path or sub-optical path. The device 100 can also adjust different uses by the synchronous movement of optical components The right IPD. The right eyepiece optics 135 and the left eyepiece optics 145 can be shifted by moving 152 and ι51, respectively, to create 1150 and IPD 15 0b. Zone 1〇1 can Displacement by movement 155. When the IPD distance i50a becomes IPD 150b, the zone simultaneously moves 155 (viewed downward from FIG. 1) and moves to the plane 170. When ipd 150b becomes IPD 150a, zone 101 is simultaneously Move away from plane 170 (viewed upwards from FIG. 1). These synchronized movements allow the device 100 to adjust to fit the entire range between IPD 150a and IPD 150b 'while maintaining the reflective surface 12b 122 and eyepiece lens 135, respectively And 145 constant lengths along the sub-diameters 130 and 140. The device 100 can also perform diopter correction by additional adjustment of the movement 153 of the left eyepiece optic 145 and the movement 154 of the right eyepiece optic 135. Two off-axis can be adjusted Aperture stop 189, 199 It is placed between the display lens 115 and the splitter 120. The aperture stop is imaged near the pupil of the viewer, and its size is appropriately adjusted to cover the movement of the pupil when the user views the corner of the virtual screen (virtual scree ...). Width. In order to accommodate a large range of viewer pupil motion, the size of the aperture should be 2-3 times larger than the size necessary to transfer the spatial frequency range required for the resolution of the display 110. In order to uniformly illuminate the aperture diaphragms 189, 99, the left and right light sources U5, 126 should have an extended (non point source) size. The display screen 110 in FIG. 1 can simultaneously transmit the same image of the display screen 110 to the left and right eyes of the user. When two light sources 125 and 126 are used for simultaneous lighting 0 \ 90 \ 90299 DOC -12- 200521559, the same display screen can be used to send the image set to the user's left eye and send a different image set to the user's Right eye. When the display screen no is displayed, the same sub-images of the display screen 10 will travel along the sub-light paths mo and mo. However, if the light sources 125 and 126 alternately illuminate the display screen, FIG. 2 is a flowchart arranged according to a specific embodiment of the present invention. According to the chart, when using a single display screen, a head mounted device (such as device 100) can be used to transmit an image different from the image transmitted to the user's right eye to the user's left eye. In general, the display of a head-mounted device (such as the display of Figure 丨 11) ′ cannot display the data transmitted as a lean stream. In Figure 2, tile training prepares multiple data streams for display on the display. For example, a data stream can be prepared for the user's left eye to view, and a second data stream can be prepared for the user's right eye to view. In block 2G2, each data stream is associated with one of a plurality of illumination sources for a suitably configured head mounted display. For example, by using the device 100 of FIG. I, the data stream prepared for the right-eye view of the user can be associated with the left light source 126, and the data stream prepared for the left-eye view of the user can be associated with the right light source 125. related. Returning to Fig. 2, block 203 interleaves multiple data streams so that the data streams can be displayed on a morning display. In block 204, the interlaced streams are displayed on a display screen, while the display screen is alternately illuminated by a light source associated with the data stream being displayed. For example, by using the device 100, when the display screen 1 () is displaying the data stream to be viewed by the right eye 13 6, the display screen i 丨 〇 will be illuminated by the left light source 126. When the display screen 11 is displaying the user's left eye to be viewed, the second shell feeder day guard 'display screen Π 〇 will be illuminated by the right light source 125. FIG. 3 graphically illustrates information according to a specific embodiment of the present invention.

The graphics set 3 10 includes a graphical representation of the data stream 3 1 and the data stream 3 1 2. When used in a manner such as the one described above-a specific embodiment can make the data stream 3 11 and the data stream alternately by sending discrete time segments of each data stream to a display 3 1 2 interlaced. For example, during time period 34 丨, a part of the data stream 3 11 is sent to the display screen for display. During time period 342, a portion of the data stream 312 is sent to the display for display. Graph 320 shows the timing of the light sources associated with the data stream 311. When a specific embodiment sends a section of the data stream 311 (such as the time section 341) to a display, the head may be illuminated by a light source associated with the data stream (shown as the light source 321 in the figure 32). The display of a wearable display. Figure 33 shows the timing of the light sources associated with the data stream 312. When a specific embodiment sends a section of the data stream 312 (such as the time section 342) to a display, the head may be illuminated by a light source associated with the data stream (shown as light source 33 in the figure 33). The display screen of the wearable display. The specific embodiments of the present invention are not limited to the stereo mirror technology depicted in Figs. 2 and 3. Any type (pauern) that interleaves a plurality of signals may be used. In practice, the specific type The number of data streams and the number of light sources will depend on the application. For example, many LCDs use color sequential illumination (c0100r sequentiai illumination), which means that red, green, and blue light pulses are sent in a sequential image. . To apply this, specific embodiments may use light sources 25 and 26, which use independently controllable red, green, and blue light sources. Another configuration of other specific embodiments for generating multiple images of the display screen 10-for example, to illuminate the display screen u 〇 with light having a polarization direction of the parent, may require the above process O: \ 90 \ 90299 DOC -14- 200521559. The specific embodiment of the present invention is not limited to such a head-mounted device configuration such as that described in FIG. Fig. 4 is a perspective view of a head-mounted device configured according to one embodiment of the present invention. The head-mounted device 400 includes a region 101 as described with respect to FIG. 1, which operates to split the display image of the display 11 into a left-eye image traveling along the left-eye optical path 140 and a right-eye image Right eye sub image with light path 1 30 traveling. Regarding the device 400, the left-eye transition optics 443 is placed along the left-eye sub-optical path 140 to adjust the left-eye sub-image before the left-eye sub-image reaches the left-eye reflector 142. The left-eye reflector 142 reflects the left-eye sub-image to the left eyepiece 460. The left eyepiece 460 is composed of compound optics. The left-eye sub-image reaches the left-eye diffuser 444 and creates a real image on the surface. The left eyepiece composite optic will create a properly enlarged virtual image for the left eye 146 from this real image. Similarly, a right-eye child image travels along the right-eye child's optical path 130 and enters 433 in the right-eye transition optics. The right-eye transition optics 433 appropriately adjusts the right-eye display sub-image to be reflected into the right eyepiece 461 via the right-eye reflector 132. The right eyepiece 461 is composed of a composite optical device. The right-eye sub-image reaches the right-eye diffuser 434 and creates a real image. A magnified virtual image is created from the real image for the right eye 136 by the composite optics. The device 400 can perform diopter correction by the movement 253 of the composite optical device 460 and the movement 254 of the composite optical device 461. The two off-axis aperture diaphragms 470, 472 can be placed between the display lens 115 and the splitter 420 to determine the spatial frequency content of the transition optics 433, 443. Therefore, in the specific embodiment of FIG. 4, the size of the aperture stop of O: \ 90 \ 90299 DOC -15- 200521559 depends on the resolution of the display, and therefore it can be used in the embodiment of FIG. 4 than in FIG. 1. A smaller pore size. The device 400 can also perform ipD s rounding by synchronous movement of separate optical blocks. The ipd 150 can be shortened by shifting the left eyepiece 460 to the right using movement 251 and shifting the eyepiece 461 to the left using movement 252. With regard to the specific embodiment of FIG. 4, the length of the child optical path 140 between the transition optics 443 and the diffuser 444 and the length between the diffuser 444 and the eyepiece 460 should be kept constant. Therefore, when the central block 401 (including the lens 443) is vertically moved away from the face plane, although the eyepiece 460 is moved to the right in the movement 251, the diffuser 444 and the left-eye reflector 142 will remain in a fixed position. Similarly, the length of the sub-optical path 130 between the transition optics 433 and the diffuser 434 and the length between the diffuser 434 and the eyepiece 461 should be kept constant. Thus, when the central block 401 (including the lens 443) moves vertically away from the face plane in motion 451, although the eyepiece 461 moves to the left in motion 252, the diffuser 434 and the right-eye reflector 132 will remain at one Fixed position. A specific embodiment of the present invention may include an aperture stop 470. The aperture stop 470 allows light to pass through the openings 471 and 472. The openings 471, 472 may be alternately arranged as shutters, which can be used to block the propagation of light reflected from the display screen 110. By using these shutters, the device 400 can control whether the image is transmitted to any eye of the user in a manner that can be easily adapted to the stereoscopic mirror technology of Figs. 2 and 3. By alternately closing the openings 471, 472, and by associating this closing behavior with the display of a particular data stream, a specific embodiment may transmit only the selected data stream to each eye. In the specific embodiment of FIG. 4, the transition images 433 and 443 are used to pass the display image to the diffusers 434 and 444 at a large magnification of about O: \ 90 \ 90299 DOC -16- 200521559. The numerical aperture of the incident real image is then increased by the diffusers 434, 444. The eyepieces 460, 461 then project the real images created on the diffusers 434, 444 into the eyes 1 36, 146 to form enlarged virtual images. The specific embodiment of the present invention is not limited to the configuration using the splitter area 101. 5 and 5A are top-down views of a head-mounted device configured according to a specific embodiment of the present invention. The device 500 includes a sub-image creation area 501. Similar to the area 101, the area 501 generates a left-eye display sub-image traveling along the sub-light path 140 and a right-eye display sub-image traveling along the sub-light path 130. The display screen 110 in zone 50 is advantageously illuminated by collimated light from light sources 570 and 580, where the light sources are configured to be at source light path 576 and source light path 586, respectively Come and project light nearby. The light source 570 is composed of a blue light source 571, and the blue light source 5 71 is arranged along the source light path 5 7 6 and is preferably located at or near the reflection focal point 524 of the display optical device 115. The blue light source 571 may be any light source capable of generating blue light, such as a light emitting diode (LED) of the Nichia NSCx100 series. The light from the blue light source 571 passes through a first color filter 574, which is configured to make an appropriate angle with the source light path 576, and is selected to allow blue light to pass and reflect green light. The green light source 572 is placed adjacent to the source light path 576 and is configured to reflect the light from the cyan filter 574 in a manner that simulates placing the green light source 572 on the same side as the blue light source 571 Position. The blue light and the reflected green light travel along the source light path 576 and pass through a second color filter 575 configured to make an appropriate angle with the source light path 576.

The specific embodiment of the present invention is not limited to the case of creating multiple independent images of a display screen by illuminating a display screen from multiple directions, and any method capable of generating multiple images from a single-display can be used. FIG. 6 illustrates a top-down view of a portion of a head mounted display according to a specific embodiment of the present invention. The device_ includes a light source 608, which is arranged at the reflection focal point ⑽, and the light of the light source is reflected and polarized by the polarization beam splitter 69 (). The light from the light source 608 is collimated by the lens 115, reflected by the display, and propagates along the light path 112. A polarization adjusting unit such as a polarization rotator 609 is arranged along the optical path 11 (), which can rotate the polarization of the light from the light source ⑽. The polarization rotator can switch the direction of linear light polarization of the exit light (exit Hght) between two or more directions. The specific embodiment of the present invention is not limited to the polarization rotator, nor is it limited to the use of linearly polarized light. Instead, specific embodiments of the invention may use linear, circular, elliptical, or any form of polarized light, and any suitable polarization adjustment unit that allows the specific embodiment to distinguish multiple sub-images may be used. The splitter 620 is an asymmetric v-mirror splitter, which is arranged near the focal point 24 of the lens 115. The surface 621 of the splitter 62 is a polarized beam splitter, and the surface 622 is a totally reflective surface. In order to transmit the image to the left eye of the user, the device 600 selects the state of the polarization rotator 609. This state will cause the light of the light source 608 to be reflected off the sub-light path 130 through the surface 621. In order to transmit the image to the right eye of the user, the device 600 selects the state of the polarization rotator 609. This state will cause the light of the light source 60 to pass through the table O: \ 90 \ 90299.DOC -21-200521559 surface 621 and Therefore, it is reflected along the sub-optical path 140 through the surface 622. The specific embodiment of FIG. 6 can also be easily adapted to the stereo mirror technology of FIGS. 2 and 3. The data stream displayed by the display screen 10 can be interleaved in a manner similar to that described above and related to the state of the polarization rotator 609.

Light source 708 propagates through a polarized beam splitter. The light source 709 is reflected by a polarized beam splitter. As a result, the display screen 110 is illuminated by the collimated light polarized in one direction from the light source 708 and illuminated by the collimated light polarized in the other direction from the light source 709. The surface 790 is a part of a reflective surface, which has no effect on the polarization of light from the light sources 708, 709. Once the light from the light sources 708, 709 is reflected from the display screen 110, it is focused by the lens 115 at the point 124. The splitter 620 is an asymmetric v-mirror splitter, where 621 is a polarized beam splitter and 622 is a full mirror, and the surface 621 will reflect the light from the light source 709 along the sub-optical path 13 and at the same time make the Light from the source 708 is reflected from the surface 622. The embodiment of FIG. 7 can be easily adapted to the stereo mirror technology of FIGS. 2 and 3. The data stream displayed by the display 110 may be interleaved in a manner similar to that described above, and then connected to the light source 708 or the light source 709. By alternately lighting the light sources 708, 709 in accordance with the display rhythm of the interlaced data stream, different data can be transmitted to each eye of the user.
