Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spectacles type display device which is worn on the head in a spectacles type to view an image.

[0002]

2. Description of the Related Art Conventionally, various types of display devices have been proposed in which an image can be viewed while the display unit is attached to the human head, and one of them is a helmet-type type which is worn on the head. There is. However, although this helmet type has a strong structure, it has a problem in that it is heavy and heavy and lacks in lightness.

Therefore, an eyeglass-type display device has been proposed which is worn on the head like glasses so that an image can be viewed. 3 and 4 show an example of the eyeglass-type display device, FIG. 3 is a top view thereof, and FIG. 4 is a perspective view seen from an oblique front side. 3 and 4,
In this display device, a display unit 3 is provided on a glasses-shaped frame 1 corresponding to human eyes, and
Ear hooks 4 are provided corresponding to the side of the head and ears, and the frame 1 and the ear hooks 4 are connected via a support shaft 2 so as to be foldable inward.

Further, in the display unit 3, in addition to the circuit unit 5 in which a video signal processing circuit, a power supply circuit and the like are arranged, a video display device such as an LCD (“liquid crystal display device”, hereinafter the same) and the like. 6 and an optical system 8 having an eyepiece 7 for forming an image reproduced on the image display 6 on human eyes. The optical system 8 is provided with a mirror, a prism, etc. in addition to the eyepiece 7 as necessary, and has a structure capable of adjusting diopter and convergence angle according to individual differences of users. ing.

Another example of the glasses-type display device shown in FIGS. 3 and 4 is a glasses-type display device as shown in FIG. 5, for example. Figure 5
3 and 4 are designated by the same reference numerals in FIG.
And the same thing as FIG. 4 is shown. In this display device, the eyeglass-shaped frame 1 is provided with the display unit 3 corresponding to the eyes of the human body and the ear hooking unit 4 corresponding to the temporal region and the ears.

Further, in the display section 3, there is provided an image display device 6 such as an LCD, and an optical eyepiece 7 for forming an image reproduced on the image display device 6 in human eyes. A system 8 is provided. On the other hand, the circuit section 5 in which the video signal processing circuit, the power supply circuit, and the like are arranged is provided in the ear hook section 4.

[0007]

However, in any of the above-mentioned conventional display devices, the frame 1 is used.
No special means has been taken to prevent the distortion of (3) from affecting the display unit 3 side. Therefore, when it is mounted on the head of the human body, the frame 1 is distorted so that the both ear-hooking portions 4 spread outward as shown by the arrow B in FIG.
In some cases, the distortion directly affects the image display device 6 and the optical system 8, and it is difficult to avoid the influence of the optical axis. Further, even if a mechanism capable of adjusting the diopter and the angle of convergence is provided, there is a possibility that the adjustment operation itself may be hindered when the frame 1 is distorted.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a glasses-type display device having a structure in which frame distortion does not affect an optical system or the like.

[0009]

In order to achieve the above object, the present invention incorporates a display section having a video display for displaying a video and an optical system having an eyepiece into a frame, and the frame is a glasses type. In a glasses-type display device mounted on the head for viewing the image, the frame and the display unit are modularized to eliminate the influence of the distortion of the frame on the display unit.

[0010]

According to this structure, by modularizing the frame and the display unit, it is easy to take a structure in which the distortion of the frame does not affect the image display device and the optical system in the display unit. Further, since the frame forming the external appearance and the display section and the like arranged inside can be designed independently, it is easy to increase the variations. In addition, independent functions simplify inspection, adjustment, and maintenance.
In addition, even when only the optical system has a dust-proof structure, only the display section needs to be considered, so that the design and the like are simplified.

[0011]

Embodiments of the present invention will be described in detail below with reference to the drawings. 1 and 2 show an example of a spectacles type display device, FIG. 1 is a partially cutaway top view, and FIG. 2 is a perspective view seen from the upper side of the oblique front side. In addition, in FIGS. 1 and 2, the same reference numerals as those in FIGS. 3 to 5 are the same as those in FIGS. 3 to 5.

1 and 2, in this display device, a display unit 3 is provided on a spectacle-shaped frame 1 corresponding to the eyes of the human body, and an ear hook corresponding to the temporal region and ears. The part 4 is provided and the frame 1
The ear hooking portion 4 and the ear hooking portion 4 are connected to each other via the support shaft 2 so as to be foldable inward.

The display unit 3 here is modularized independently of the frame 1, and has a support shaft 10 and an elongated hole 11 that are vertically provided upright in the frame 1 at an intermediate position between the left and right sides. It is attached so as to be rotatable in the left-right direction and movable in the front-back direction via the.

On the other hand, in the display section 3, in addition to the circuit section 5 in which a video signal processing circuit, a power supply circuit, etc. are provided, a video display 6 such as an LCD and the like, and a display on the video display 6 are provided. And an optical system 8 having an eyepiece 7 for forming an image of the reproduced image on the human eye. This optical system 8
If necessary, in addition to the eyepiece 7, a mirror, a prism, etc. are provided, and the diopter adjustment and the convergence angle adjustment can be performed according to the individual difference of the user, and the dust-proof structure is also provided. There is.

Therefore, in the glasses-type display device having the structure of this embodiment, when it is mounted on the head 3 of a human, for example, the both ear hooks 4 are spread outward in the direction of arrow B in FIG. When 1 distorts and tries to affect the display unit 3, the middle of the frame 1 bends and absorbs it.
At the connecting portion A between 0 and the long hole 11, the display unit 3 rotates in the left-right direction or moves in the front-back direction, and the influence of this distortion can be automatically removed and eliminated.

In the above embodiment, the structure in which the frame 1 and the display unit 3 are modularized is disclosed, but it is possible to further modularize the image display unit 6 and the optical system 8. is there.

[0017]

As described above, according to the glasses-type display device of the present invention, the frame and the display unit are modularized, so that the distortion of the frame does not affect the image display unit and the optical system in the display unit. It becomes easy to take a simple structure. Further, since the frame forming the external appearance and the display section and the like arranged inside can be designed independently, it is easy to increase the variations. In addition, independent functions simplify inspection, adjustment, and maintenance.
In addition, even in the case where only the optical system has the dustproof structure, it is only necessary to consider the display section, and therefore the design and the like can be simplified.
