[0002]

2. Description of the Related Art In a conventional display device, a desk-top type liquid crystal display, a CRT display device and a projection type display device are used to reduce the size and space. A known example of this is Japanese Patent Laid-Open No. 4-113417.

[0003]

In the above-mentioned conventional technique, the downsizing of the computer is accompanied by the downsizing of the display device, and a display device for covering a half face of a goggle size has also been developed. But it's still heavy and you can only see the display screen. The present invention is
Further downsizing has been promoted to reduce weight, and it has been installed only on the eyes. Also, by making it possible to easily switch between the time of use and the time of non-use, it becomes possible to view it as an ordinary lens without removing it when not in use.
(Corresponding to claims 1 to 4 and 6 to 8). Also, by mounting on both eyes, it becomes possible to see a realistic stereoscopic image (corresponding to claim 5). Similarly, eyeglass-sized ones also enable the above items. (Corresponding to claims 9 to 13)

[0004]

In order to achieve the object of claim 1, the size is set to a contact lens size, and the display unit is made extremely small so as not to obstruct the field of view. In order to achieve the object of claim 2, an optical sensor is used for switching, and an autofocus lens is used for focusing. In order to achieve the object of claim 3, the time is measured by cooperating with the optical sensor. In order to achieve the object of claim 4, a solar cell and a dedicated charger are used. In order to achieve the object of claim 5, a transmitting device capable of displaying left and right separately is used. In order to achieve the object of claim 6, liquid crystal or the like is used for the display section. In order to achieve the object of claim 7, a device for transferring image data by a wireless method is used. In order to achieve the object of claim 8, the microminiature display device according to claims 1 to 7 is used.
In order to achieve the objects of claims 9 to 12, the size is changed to the size of glasses, a power switch is used, and the technical means for achieving the objects of claims 2 to 4 are used. Correspond. In order to achieve the object of claim 13, claim 9
The small-sized display device described in 1 to 12 is used.

[0005]

In order to reduce the size and weight of the display device, the size of the main body is changed to the contact size and the size of the glasses, and the display unit, the optical sensor, the rechargeable battery charged by the solar battery, the receiving device, and the display control device This can be done by forming a part into a film. Furthermore, by combining with various transmitters corresponding to this display device, the range of use can be expanded, and the purpose of being applied to various products requiring screen display can be achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be described.

A contact lens-sized special lens 11 with autofocus, a film-shaped display unit 12, an optical sensor 1
FIG. 1 shows the rechargeable battery 14, which is charged by a solar cell, the receiving device 15, and the display control device 16, which are attached to each other. Next, the one shown in FIG. 1 is put on the eye, the rechargeable battery 14 is used, and the eyes are closed to turn on the power. Transmitter 2
Change the initial state and set it as the user's condition. The image is adjusted by a special lens 11 having an autofocus function. After that, the data wirelessly transferred from the transmitter 2 is processed by the display controller 16 and displayed on the display unit 12 using liquid crystal or the like. When not in use, open your eyes and turn off the power. The rechargeable battery 14 is charged by a solar cell. The display section 12 is visible because it does not obstruct the normal field of view.

A special lens 31 with automatic focus is attached to a frame 37 of glasses size, and a film-shaped display section 32, a power switch 33, a rechargeable battery 34 charged by a solar cell, a receiving device 35, and a display control device 36 are provided. The thing is shown in FIG. Next, the one shown in FIG. 2 is worn by wearing glasses, and the power is turned on by the power switch 33. The transmitter 2 changes the initial state and sets it as the user's condition. After that, the data wirelessly transferred from the transmitter 2 is processed by the display controller 36 and displayed on the display unit 32 using liquid crystal or the like. When not in use, the power switch 33 is turned off. Rechargeable battery 34
Is charged by solar cells. The display unit 32 is transparent and the front can be seen.

[0009]

According to the present invention, the cable connection to the display device is not required, and the display device is attached to the eyes, so that there is an effect that it is ultra-compact and lightweight and the range of use is expanded. Also, when not in use, it looks transparent like an ordinary lens, so that there is no need to attach and detach like a goggle type, and there is an effect of improving usability.
