Abstract

PURPOSE:To watch a stable and powerful picture by fitting an elastic pad to an eye-contact part of a frame to improve the wear performance. CONSTITUTION:A pad 11 made of a light, volatile material offering well skin touch such as felt or sponge is fitted to a frame 2 so as to surround its eye- contact part. Then the frame 2 is supported and fixed by the pad 11, ears and a nose. Since the frame 2 is fitted to the face through the elastic pad 11, the position deviation between an optical system 3 and eyes is prevented and a video image is watched stably even for the use for a long time and the fatigue is relieved. Furthermore, since the pad 11 has a light shield property, the leakage of an external light from the surrounding to the optical system 3 is prevented and other than the picture is not visible, even a subminiature pattern is sensed to be a large pattern by the optical system 3 with a wide visual field and the clear and powerful video image is watched.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spectacle type display in which a liquid crystal display device and a magnifying lens are housed in a spectacle type frame.

[0002]

2. Description of the Related Art A conventional glasses type display 1 is shown in FIG.
As shown in Fig. 3, it usually has an appearance similar to sunglasses, and the part corresponding to the lens of the glasses-type frame 2 is
A pair of optical systems 3 in which a liquid crystal display device and a magnifying lens are arranged on the same optical axis are housed. When the display 1 is attached to the user's face 4 as shown in FIG. 4, both ends of the frame 2 are placed on the ears 5 as in general glasses.
The nose 6 supports the center.

[0003]

However, according to the conventional glasses-type display 1 configured as described above, even if the position of the relatively heavy display 1 is fixed by the ear 5 and the nose 6, it is usually The mounting position is more likely to shift than the eyeglasses. On the other hand, if the positions of the optical system 3 and the eye shift,
A clear and beautiful image cannot be seen due to the effects of lens aberration. Further, when the display 1 is attached, the weight of the display 1 is applied to the ears 5 and the nose 6, so that it is likely to cause damage and fatigue.

Furthermore, if external light such as sunlight or illumination light from above or behind the head enters the optical system 3, it will interfere with viewing. For the display 1, for example, a micro liquid crystal device having a 0.7 inch screen is used. The feature is that the screen is magnified with a magnifying lens to make it look like a large screen, but with the conventional display 1, when you wear it, you can see the surrounding scene, and you can not see it on the large screen and you can not get enough power There was a problem such as being lost.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a glasses-type display which has improved wearability and allows a stable and powerful image to be viewed.

[0006]

The eyeglass type display according to claim 1, wherein an eyeglass of the frame 2 is provided in an eyeglass type display 1 in which an optical system 3 including a liquid crystal display device and a magnifying lens is housed in the eyeglass type frame 2. It is characterized in that a pad 11 having elasticity is attached to the portion.

The spectacles type display according to claim 2 is characterized in that the pad 11 is made of felt.

The spectacles type display according to claim 3 is characterized in that the pad 11 is made of sponge.

[0009]

In the eyeglass-type display having the above structure,
Since the pad 11 made of an elastic material such as felt or sponge is attached to the eyepiece portion of the frame 2, the wearability of the frame 2 is improved, the positional deviation between the optical system 3 and the eye is prevented, and when used for a long time. Can also provide a stable image. In addition, since the reflection of external light from the surroundings into the optical system 3 is prevented and only the image is visible, a powerful and clear image can be viewed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the glasses type display of the present invention will be described below with reference to the drawings.

1 and 2 show the structure of an embodiment of the present invention. In these figures, the portions corresponding to those of the conventional example shown in FIGS. 3 and 4 are designated by the same reference numerals, and the description thereof will be omitted as appropriate. The feature of this embodiment is that the frame 2
The point is that a pad 11 made of a lightweight, highly volatile and soft material such as felt or sponge is attached so as to surround the eyepiece part. And pad 11, ear 5
And the frame 2 is held and fixed by the nose 6.

According to the present embodiment, the elastic pad 11
Since the frame 2 is held on the face 4 via the, the frame 2 fits the face 4 even if there is an individual difference in the shape of the face 4. Therefore, it is possible to prevent positional deviation between the optical system 3 and the eye, to view a stable image even when used for a long time, and reduce fatigue. Further, since the pad 11 has a light-shielding property, it is possible to prevent external light from being reflected on the optical system 3 from the surroundings, and moreover, only the image can be seen. You can see a clear and powerful image on the big screen.

In the glasses-type display 1, since the adjusting mechanism of the optical system 3 has a structure that can be adjusted regardless of the position of the pad 11, the optical system 3 can be easily adjusted after mounting.

[0014]

As described above, according to the glasses-type display of the present invention, since the pad formed of the elastic material such as felt or sponge is attached to the eyepiece portion of the frame, the wearability of the display is improved. Improved, stable and powerful images can be seen clearly.
