Abstract

PURPOSE:To make the motion of the user of the display device free, to attain a cordless way and to save the installing space of a display device by providing a mechanism where a display part can be freely set at the periphery of the eyes of a user. CONSTITUTION:A light transmitting part 3 modulates the video signal 5 edited in a terminal system and outputs the signal 5 after modulating it into an optical signal 6. A photodetecting part 4-1 receives the signal 6 from the part 3, and a demodulating part 4-2 demodulates the signal 6 received at the part 4-1 into the signal 5. A display part (small-sized monitor) 4-3 displays an image based on the signal 5 demodulated at the part 4-2. Under such conditions, the part 4-3 can be set at the periphery of the eyes of a user and therefore the user can finely view the image shown at the part 4-3. Thus the sides of the parts 4-1, 4-2 and 4-3 are connected to the terminal system and the part 3 without using any cord and with use of the signal 6. At the same time, the user wearing the part 4-3 at the periphery of his eyes can move in an easy and free way. Furthermore the installing space of a display device can be saved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device connected to a terminal system using light.

[0002]

2. Description of the Related Art A conventional eyeglass-type display device (display) is connected to a terminal system such as a computer (including a personal computer) or a word processor by an electric wire.

[0003]

However, since the conventional eyeglass-type display device is connected to the terminal system by an electric line, it is inconvenient that the user cannot move freely or is caught on the cord of the electric line. It was In addition, the space of the cord of the electric wire became necessary. The purpose of the present invention is to
In view of such conventional problems, it is an object of the present invention to provide a space-saving display device in which the user of the display device can move freely.

[0004]

A display device according to the present invention is, in a display device connected to a terminal system, an optical transmission section for modulating a video signal edited by the terminal system, converting the video signal into an optical signal and outputting the optical signal. A light receiving unit that receives the optical signal output from the optical transmission unit, a demodulation unit that demodulates the reception signal of the light receiving unit into a video signal, and a display unit that displays as an image based on the video signal demodulated by the demodulation unit The display unit is characterized by having a mechanism that can be attached and detached around the eyes of the user.

[0005]

In the display device having the above structure, the optical transmission section modulates the video signal edited by the terminal system, converts it into an optical signal, and outputs it. The light receiving unit receives the optical signal output from the optical transmission unit. The demodulation unit demodulates the reception signal of the light receiving unit into a video signal. The display unit displays a video based on the video signal demodulated by the demodulation unit. In this case, the display unit has a mechanism that is detachable around the eyes of the user, so the user can use this mechanism (for example, a mechanism in the form of eyeglasses) to move the display unit around the eyes. By wearing it, you can see the image on the display well.

As a result, a user who uses the display device can move more freely than in the conventional case, and space is saved because an electric wire cord is unnecessary.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a display device according to the present invention. In the figure, the computer main body 1 is electrically connected to a keyboard 2 as an input means. The computer main body 1 supplies the video signal 5 sent to the display device to the optical transmission unit 3 and converts it into an optical signal.
Here, the display device comprises an optical transmission section 3 and a monitor 4 with a spectacles type light receiving section. The terminal system is composed of a keyboard 2 and a computer body 1. In addition,
As the terminal system, various systems using a word processor, a personal computer, etc. can be considered. The video signal 5 is, for example, an information signal such as a character or a figure input by the keyboard 2 and edited,
Alternatively, it may be an image information signal input using a mouse.

The optical transmission section 3 is composed of a modulation section 3-1 connected to the computer main body 1 and a light emitting section 3-2 connected to the modulation section 3-1. First, the modulator 3-1
Modulates the video signal from the computer main body 1 and emits it to the space as an optical signal 6 by the light emitting section 3-2. The optical signal 6 is received by the monitor 4 with a spectacles type light receiving section and displayed.
Here, the eyeglass-type light-receiving unit-equipped monitor 4 includes a light-receiving unit 4-1 that receives an optical signal 6 and converts it into an electric signal, and a demodulation unit 4-2 that returns the electric signal from the light-receiving unit 4-1 to a video signal 7. When,
As shown in FIG. 2, it is composed of a small monitor 4-3 as a display unit of the present invention which displays an image on a display screen having a spectacles shape by a video signal from the demodulation unit 4-2. In addition,
The small monitor 4-3 has a shape of eyeglasses and can be worn in the same manner as ordinary eyeglasses. , Therefore, the light receiving unit 4
-1 converts the optical signal 6 into an electric signal, and the demodulation unit 4-2 demodulates the electric signal and displays it on the small monitor 4-3.

FIG. 2 is an external view showing an embodiment of a display device according to the present invention, and the same reference numerals are used for the same or corresponding parts as in FIG. FIG. 1 actually has an external configuration as shown in FIG. 2, for example.

With the above arrangement, the monitor 4 side with the spectacles type light receiving section and the computer main body 1 and the optical transmission section side can be connected using the optical signal 6 to be cordless, and a person handling a computer. 2 is very convenient because it is easy to move freely while wearing the glasses-type monitor with light-receiving section 4 as shown in FIG. Further, the cordless structure is very convenient because the cord of the electric wire is not hooked as in the conventional case. In addition, the cordless structure eliminates the need for dragging the cord of the electric wire to move, thus saving space. Further, in the conventional case, since the cord is moved by dragging it, various kinds of precautions such as hooking the cord are taken into consideration, but the present invention eliminates such fatigue.

The present invention is not limited to this embodiment, and various applications and modifications are conceivable without departing from the gist of the present invention.

[0012]

As described above, according to the present invention, the following effects can be obtained. (1) The light receiving unit, the demodulation unit, and the display unit side can be connected to the terminal system and the optical transmission unit side by using an optical signal to be cordless, and a person handling a computer can display the display unit around the eyes. It is very convenient because you can move freely while wearing it. (2) The cordless structure is very convenient because the user of the display device does not have to hook the cord of the electric wire as in the conventional case. (3) Due to the cordless structure, the user of the display device does not move by dragging the cord of the electric wire as in the conventional case, which saves space. (4) In the conventional case, since the user of the display device moves by dragging the cord, various cautions such as whether or not to hook the cord cause fatigue, but the present invention eliminates such fatigue. ..
