[0008] An embodiment of the present invention (hereinafter referred to as the present embodiment) will be described below with reference to the drawings. In the following description, a head-mounted display 1 will be referred to as an "HMD (Head Mounted Display) 1." In the following description, the directions indicated by X1 and X2 in the drawings will be referred to as right and left, respectively, the directions indicated by Y1 and Y2 in the drawings will be referred to as up and down, respectively, and the directions indicated by Z1 and Z2 in the drawings will be referred to as forward and backward, respectively. These directions indicate directions as seen by a user wearing the HMD 1. However, the left-right, up-down, and front-back directions do not indicate strict directions.

[0009] [Overview of HMD 1] Fig. 1A is a perspective view of an HMD according to this embodiment as seen from the front left. Fig. 1B is a left side view of the HMD according to this embodiment as seen from the left. In the following description, the state in which the HMD 1 is worn by a user is referred to as the "usage state." In the usage state, the HMD 1 covers the area in front of the user's eyes.

[0010] The HMD 1 preferably includes a wearing band that surrounds the user's head and a main body housing that is supported on the front of the wearing band. The main body housing contains the display unit 100 and various components that constitute the optical system, such as an eyepiece 200.

[0011] The display unit 100 includes a display panel 10, which will be described later. The display panel 10 may display two-dimensional or three-dimensional images. The display panel 10 may be, for example, a liquid crystal display or an organic electroluminescence display device, but the type of the display panel 10 is not particularly limited.

[0012] The HMD 1 shown in Figures 1A and 1B is an example and is not limited thereto. The HMD 1 is only required to be worn on the user's head and to include a display panel that displays images, and the shapes of the attachment band and main body housing are not limited to those shown. Also, Figure 1B shows the display unit 100 and eyepiece 200 schematically, and the shapes and sizes of these are not limited to those shown.

[0013] Next, the configuration of the display panel and optical system in this embodiment will be described in detail with reference to Figures 2 and 3. Figure 2 is a diagram schematically illustrating the configuration of the display panel and optical system in this embodiment. Figure 3 is a plan view showing a front view of the display panel in this embodiment. While Figure 2 illustrates a display panel and optical system on either the right eye side or the left eye side of the user U, the configuration shown in Figure 2 may be provided on both the right eye side and the left eye side. However, the configuration is not limited to a compound eye lens, and a single eye lens may also be used.

[0014] [Eyepiece 200] The eyepiece 200 constitutes part of the optical system of the HMD 1. When in use, the eyepiece 200 is located in front of the right or left eye of the user U, and is a convex lens that focuses the image light IL emitted from the display panel 10 toward the eyeball of the user U. The eyepiece 200 has the function of enlarging the image displayed on the display panel 10 so that the user can view it. Note that the eyepiece 200 may be composed of two or more lenses. The eyepiece 200 may also be a Fresnel lens or a liquid crystal lens.

[0015] 2, the optical axis 200C of the eyepiece 200 is indicated by a dashed line. The optical axis is an imaginary axis that passes through the center of the lens and is perpendicular to the surface of the lens.

[0016] [Display Unit 100] The display unit 100 includes a plurality of display panels 10 and a plurality of lens units 20 provided corresponding to each of the plurality of display panels 10. In this embodiment, an example will be described in which the plurality of display panels 10 are a front panel 10C, a right panel 10R, and a left panel 10L. The front panel 10C, the right panel 10R, and the left panel 10L may be, for example, micro OLEDs of 0.49 inches or less. By arranging three 0.49-inch (2K) micro OLEDs side by side, it is possible to create a micro OLED equivalent to a 1.5-inch (6K) micro OLED in appearance. The cost of using three 0.49-inch micro OLEDs is approximately one-tenth of the cost of using a 1.5-inch micro OLED.

[0017] In this embodiment, an example will be described in which the multiple lens units 20 are a front lens unit 20C, a right lens unit 20R, and a left lens unit 20L. These lens units 20, together with an eyepiece lens 200, form an optical system. The lens units 20 are disposed in front of the display panel 10 and are not in contact with the display panel 10. The distance between the lens units 20 and the display panel 10 may be appropriately set to obtain a desired focal length. Note that the distance between the center of the right lens unit 20R and the center of the right panel 10R may be longer than the distance between the center of the front lens unit 20C and the center of the front panel 10C. Similarly, the distance between the center of the left lens unit 20L and the center of the left panel 10L may be longer than the distance between the center of the front lens unit 20C and the center of the front panel 10C. This can improve aberrations. The center of the right lens unit 20R is the portion that faces the right panel 10R and through which the optical axis OR passes, and the center of the right panel 10R is the portion that faces the right lens unit 20R and is located in the center in the vertical and horizontal directions. Similarly, the center of the left lens unit 20L is the portion that faces the left panel 10L and through which the optical axis OL passes, and the center of the left panel 10L is the portion that faces the left lens unit 20L and is located in the center in the vertical and horizontal directions.

[0018] In this embodiment, when there is no need to distinguish between the front panel 10C, the right panel 10R, and the left panel 10L, they will simply be referred to as the "display panel 10." Similarly, when there is no need to distinguish between the front lens unit 20C, the right lens unit 20R, and the left lens unit 20L, they will simply be referred to as the "lens unit 20."

[0019] 3, the front panel 10C includes a display area DC and a frame area FC surrounding the display area DC. The display area DC includes a plurality of unit pixels and is an area where an image is displayed. The frame area FC is an area where no image is displayed.

[0020] 2, the front panel 10C is provided in front of the eyepiece 200. Specifically, the front panel 10C is provided on an extension of the optical axis 200C of the eyepiece 200.

[0021] 3, the right panel 10R includes a display region DR and a frame region FR surrounding the display region DR. The display region DR includes a plurality of pixels and is an area where an image is displayed. The frame region FR is an area where no image is displayed.

[0022] The right panel 10R is provided adjacent to the right side of the front panel 10C. Therefore, the left portion of the frame region FR of the right panel 10R and the right portion of the frame region FC of the front panel 10C are provided adjacent to each other. The right panel 10R is not provided on an extension of the optical axis 200C of the eyepiece 200. The right panel 10R is provided to the right of the optical axis 200C and faces the eyepiece 200.

[0023] 2, the display surface of the display region DR of the right panel 10R is inclined relative to the display surface of the display region DC so that the right portion of the right panel 10R is closer to the eyepiece lens 200. Specifically, the display surface of the display region DR of the right panel 10R is inclined at 6.5 degrees relative to the display surface of the display region DC of the front panel 10C. However, the present invention is not limited to this, and the display surface of the display region DR of the right panel 10R may be inclined at 6 to 7 degrees relative to the display surface of the display region DC of the front panel 10C.

[0024] 3, the left panel 10L includes a display area DL and a frame area FL surrounding the display area DL. The display area DL includes a plurality of pixels and is an area where an image is displayed. The frame area FL is an area where no image is displayed.

[0025] The left panel 10L is provided adjacent to the left side of the front panel 10C. Therefore, the right portion of the frame region FL of the left panel 10L and the left portion of the frame region FC of the front panel 10C are provided adjacent to each other. The left panel 10L is not provided on an extension of the optical axis 200C of the eyepiece 200. The left panel 10L is provided to the left of the optical axis 200C and faces the eyepiece 200.

[0026] 2, the display surface of the display area DL of the left panel 10L is inclined relative to the display surface of the display area DC so that the left portion of the left panel 10L is closer to the eyepiece lens 200. Specifically, the display surface of the display area DL of the left panel 10L is inclined at 6.5 degrees relative to the display surface of the display area DC of the front panel 10C. However, the present invention is not limited to this, and the display surface of the display area DL of the left panel 10L may be inclined at 6 to 7 degrees relative to the display surface of the display area DC of the front panel 10C.

[0027] Each display panel 10 may be a flexible panel having flexibility. For example, the left panel 10L and the right panel 10R may be flexible panels that are curved.

[0028] [Display unit 100: lens section 20] Front lens section 20C is provided in front of eyepiece lens 200. Specifically, front lens section 20C is provided on an extension of optical axis 200C of eyepiece lens 200. Therefore, front lens section 20C is provided opposite front panel 10C.

[0029] The front lens unit 20C is a convex lens that guides the image light IL emitted from the display area DC to the eyepiece 200 and enlarges the display area DC so that it can be viewed by the user. The front lens unit 20C is disposed so that its optical axis OC is perpendicular to the display surface of the front panel 10C. The size of the front lens unit 20C is preferably approximately the same as that of the front panel 10C or large enough to cover at least half of the display surface of the front panel 10C.

[0030] The right lens unit 20R is provided adjacent to the right side of the front lens unit 20C. The right lens unit 20R is provided to the right of the optical axis 200C and faces the eyepiece 200. The right lens unit 20R is not provided on an extension of the optical axis 200C of the eyepiece 200.

[0031] The right lens unit 20R is a convex lens that guides the image light IL emitted from the display region DR to the eyepiece lens 200, enlarging the display region DR for viewing by the user. The right lens unit 20R is disposed so that its optical axis OR is perpendicular to the display surface of the right panel 10R. Therefore, the optical axis OR is inclined with respect to the optical axis OC. Specifically, the optical axis OR of the right lens unit 20R is inclined at 6.5 degrees with respect to the optical axis OC of the front lens unit 20C. However, this is not limited thereto, and the optical axis OR of the right lens unit 20R may be inclined at 6 to 7 degrees with respect to the optical axis OC of the front lens unit 20C. The size of the right lens unit 20R is preferably approximately the same as that of the right panel 10R, or large enough to cover at least half of the display surface of the right panel 10R.

[0032] The left lens unit 20L is provided adjacent to the left side of the front lens unit 20C. The left lens unit 20L is provided to the left of the optical axis 200C and faces the eyepiece 200. The left lens unit 20L is not provided on an extension of the optical axis 200C of the eyepiece 200.

[0033] The left lens unit 20L is a convex lens that guides the image light IL emitted from the display area DL to the eyepiece lens 200, enlarging the display area DL for viewing by the user. The left lens unit 20L is disposed so that its optical axis OL is perpendicular to the display surface of the left panel 10L. Therefore, the optical axis OL is inclined with respect to the optical axis OC. Specifically, the optical axis OL of the left lens unit 20L is inclined at 6.5 degrees with respect to the optical axis OC of the front lens unit 20C. However, this is not limited thereto, and the optical axis OL of the left lens unit 20L may be inclined at 6 to 7 degrees with respect to the optical axis OC of the front lens unit 20C. The size of the left lens unit 20L may be approximately the same as that of the left panel 10L, or may be large enough to cover at least half of the display surface of the left panel 10L.

[0034] In this embodiment, the lens unit 20 is an aspherical lens, but this is not limited thereto, and a spherical lens or a free-form lens may also be used. Furthermore, in this embodiment, as shown in FIG. 2, the front lens unit 20C, the right lens unit 20R, and the left lens unit 20L are integrally configured. However, this is not limited thereto, and these may be separate units. When the front lens unit 20C, the right lens unit 20R, and the left lens unit 20L are integrally configured, it is possible to easily improve the relative positional accuracy of each lens unit. On the other hand, when the front lens unit 20C, the right lens unit 20R, and the left lens unit 20L are separate units, as shown in FIG. 2, the front lens unit 20C, the right lens unit 20R, and the left lens unit 20L may be lenses with the same curved surface shape, thereby reducing mold costs and avoiding complex process management. However, the front lens unit 20C, the right lens unit 20R, and the left lens unit 20L may have different shapes.

[0035] [Display Image] Next, a display image in the HMD 1 of this embodiment will be described mainly with reference to Figs. 4A to 5B. Fig. 4A is a diagram showing an example of a display image when a grid pattern is displayed in each display area. Fig. 4B is a diagram showing an example of a display image when a circular object is displayed. Fig. 5A is a diagram showing an example of a display image that the user can view through the lens unit when a grid pattern is displayed in each display area. Fig. 5B is a diagram showing an example of a display image that the user can view through the lens unit when a circular object is displayed. Note that the upper parts of Figs. 4A to 5B show plan views showing the display panel as viewed from the front (i.e., the plan view shown in Fig. 3), and the lower parts show display images that the user can view.

[0036] Display area DC, display area DR, and display area DL together form a single image. However, as described with reference to Fig. 3, each display panel 10 has a frame area, and therefore, as shown in the lower part of Fig. 4A and Fig. 4B, the single image is displayed with interruptions via the frame area. In other words, the image displayed by display area DC and the image displayed by display area DR are discontinuous, and the image displayed by display area DC and the image displayed by display area DL are discontinuous.

[0037] 4A shows a grid pattern displayed in each display area. As described above, due to the presence of the frame area, the grid patterns displayed in each display area are perceived as being spaced apart from each other.

[0038] 4B shows how portions of a circular object are displayed in each display area. As described above, due to the presence of the frame area, discontinuous objects are visually recognized.

[0039] Therefore, in this embodiment, a configuration is adopted in which a lens unit 20 is provided corresponding to each display panel 10. Therefore, the images displayed by each display area can be visually recognized by the user U as one continuous image.

[0040] The lower part of Fig. 5A shows how the spacing between lattice points in the lattice pattern is perceived as being wider than that in the lower part of Fig. 4A. Also, Fig. 5B shows how a single continuous circular object is perceived. The reason why a single continuous object is perceived in this manner is because each lens unit 20 is provided so that the image displayed in each display area is enlarged and perceived.

[0041] When a user views the display areas through the lens unit 20, each display area appears distorted, as shown in the lower part of Fig. 5A. This can be corrected by electronic means. In other words, by correcting the distortion by taking into account the amount of distortion caused by the lens and displaying an image that is the inverse of the distortion, each display area appears to have a rectangular outline, as shown in the lower part of Fig. 5B.

[0042] [Summary] The HMD 1 according to this embodiment allows a user to view high-resolution images with a wide angle of view using an inexpensive, small panel. Furthermore, by adopting a configuration in which multiple lens units 20 are provided corresponding to each of the multiple display panels 10, a continuous image can be viewed by the user even when using a display panel 10 with a frame area.

[0043] Furthermore, using multiple small display panels can reduce costs compared to using one large display panel, because the purchase cost of commercially available display panels can be as much as 10 times or more if a display panel with a display area twice as large is used.

[0044] Generally, in an HMD requiring a wide viewing angle, increasing the resolution of the eyepiece requires the addition of a lens with a diameter and thickness comparable to that of the eyepiece. This results in the HMD becoming larger in the front-to-back direction. In this embodiment, by adopting a configuration in which multiple lens units 20 are arranged side by side in addition to the eyepiece 200, the focal length of the optical system can be shortened without increasing the thickness of the eyepiece 200 or increasing the curvature of the lens surface. Therefore, an HMD 1 can be provided that achieves high resolution of the displayed image without increasing the size in the front-to-back direction (depth direction). It is preferable that no other lenses are provided between the eyepiece 200 and the lens units 20 in the front-to-back direction.

[0045] Furthermore, the imaging performance of the eyepiece 200 is higher on the side closer to the optical axis 200C and lower on the outer edge of the eyepiece 200. That is, images tend to appear blurred on the outer edge of the eyepiece 200 compared to the vicinity of the optical axis 200C. In this embodiment, by providing a lens unit 20 corresponding to each display area, it is possible to improve visibility even in the area on the outer edge of the eyepiece 200. Furthermore, as described above, in this embodiment, the right panel 10R and the left panel 10L are tilted relative to the front panel 10C so as to approach the eyepiece 200, which makes it possible to improve visibility even in the area on the outer edge of the eyepiece 200.

[0046] 3, flexible wiring boards 80C, 80R, and 80L for supplying image signals to the display area of ​​each display panel 10 are preferably provided on the display panel 10. The flexible wiring boards 80C, 80R, and 80L may also be wiring boards for supplying power.

[0047] The flexible wiring boards 80C, 80R, and 80L may be provided so as to extend in a direction perpendicular to the direction in which the display panels 10 are arranged (the left-right direction in this embodiment). In Fig. 3, each flexible wiring board is attached to the top of each display panel 10 and extends upward.

[0048] [First Modification] A first modification of the present embodiment will be described with reference to Fig. 6. Fig. 6 is a diagram showing a display panel in the first modification.

[0049] In the above-described embodiment, an example has been described in which the display unit 100 has three display panels 10, but the number of display panels 10 is not limited to this. For example, as shown in Fig. 6, the display unit 100 may have six display panels 10. In this case, it is preferable that the display panels are arranged adjacent to each other in the left-right and up-down directions, as shown in Fig. 6.

[0050] As shown in FIG. 6 , by using an odd number of display panels 10 aligned horizontally, the display area D of the display panel 10 positioned in the center of the horizontal direction can be located on an extension of the optical axis 200C of the eyepiece lens 200. However, this is not limited to this, and an even number of display panels 10 may be aligned horizontally. In this case, it is preferable to position the display panels 10 so that the frame area F is not positioned on an extension of the optical axis 200C of the eyepiece lens 200. This is because the area near the extension of the optical axis 200C is the area that is most easily visible to the user. If the frame area F were positioned on an extension of the optical axis 200C and the seams of the viewed image did not match, the user may experience a strong sense of discomfort.

[0051] The number of display panels 10 and lens units 20 is not limited to the examples in Fig. 2 and Fig. 6. At least a plurality of display areas D may be provided, and the number of lens units 20 may be the same as the number of display areas D.

[0052] [Second Modification] A second modification of the present embodiment will be described with reference to Fig. 7. Fig. 7 is a diagram showing a display panel in the second modification. Note that the upper part of Fig. 7 shows one display panel 10, and the lower part of Fig. 7 shows a display area D that can be viewed without using the lens unit 20.

[0053] In the above embodiment and first modification, an example has been described in which the display unit 100 includes a plurality of display panels 10, but the number of display panels 10 may be one.

[0054] Even when a single display panel 10 is used, the visibility on the outer edge side of the eyepiece lens 200 can be improved by adopting a configuration with multiple lens units 20. Here, in a configuration in which multiple lens units 20 are arranged side by side facing a single display panel 10, the lens units 20 enlarge the display area D, resulting in overlapping views of some of the display areas D. Therefore, in the second modification, instead of the frame area F, a non-display area ND may be intentionally provided in the display area D. Specifically, as shown in FIG. 7 , a non-display area ND may be provided. This results in multiple display areas displaying discontinuous images via the non-display area ND. Alternatively, the same image may be displayed in the overlapping portions of the display area D viewed through the lens units 20.
