Abstract

PURPOSE:To resolve disagreement between communicators about line of sight by installing many minute reflecting mirrors in an area that is not in direct relation to internal display of a plane display unit. CONSTITUTION:Light from a backlight 15 is converted to a uniform surface light source by way of scattering plate 14, modulated by a polarized plate 11 and liquid crystal panel 12, and an image is displayed. On the other hand, light from the front of liquid crystal panel 2 is reflected by minute reflecting mirrors 13, reaches a television camera 20 by adjusting the angle of these minute reflecting mirrors 13, and a resulting reflected image can prepare a field body M. The minute reflecting mirrors 13 play a role of suppressing bleeding between picture elements in an ordinary liquid crystal, and also of black stripes installed to suppress entering of light in TFT when active matrix is used. With this, those communicating remotely with each other can make their lines of sight match with each other.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a display/imaging device that is a combination of a display device and an imaging device, and is used in two-way video communication systems such as video telephones and video conferences. It is.

[Background Art] In recent years, due to rapid progress in communication technology, two-way video communications such as video conferences and video telephones that connect remote locations via video/audio communication networks have rapidly become popular. FIG. 3 shows the basic configuration of a terminal used in such a system. In FIG. 3, 1 is a CRT, 2 is a television camera, and 3 is a microphone. In addition, there are audio/video interfaces, encoding devices, and network control devices (not shown).
Connected to a communication network.

[Problems to be Solved by the Invention] In such a terminal, an image of the subject M is captured by the television camera 2, which is an imaging device installed above or beside the CRTl, which is a display device. Subject M is usually looking at the other person on CRT 1, and TV camera 2
is not suitable for Therefore, the lines of sight of the communicators who meet each other via the system do not essentially match. This shift in line of sight not only makes the communicators feel uncomfortable, but also causes them to refute the other party's claims or interrupt the discussion.
In the case of a dialogue where it is important to review the other party, this has the disadvantage of affecting the dialogue itself.

SUMMARY OF THE INVENTION An object of the present invention is to provide a display/imaging device that eliminates the mismatch in line of sight between callers, which is a drawback of conventional two-way video communication systems such as video telephones.

[Means for Solving the Problems] A 71% display image device according to the present invention has a large number of minute reflecting mirrors provided in a region inside a flat display that is not directly involved in display.

[Operation] In the present invention, the object in front of the flat display is imaged by the imaging device as a reflected image by a microreflector.

Embodiment] The overall configuration of an embodiment of the display/imaging device of the present invention is described in the first embodiment.
FIG. 2 shows an example of the internal configuration of the flat display used therein.

In these figures, 10 is a flat display which is a display device, and polarizing plates 11. LCD panel 12, this LCD panel 12
It consists of a micro reflecting mirror 13 etc. built into the inside of the mirror. 14
1 is a scattering plate, 15 is a backlight, and 20 is a television camera.

FIG. 2 shows details of the liquid crystal panel 12 and the polarizing plate 11 on the scattering plate 14 side in FIG. 1. In this figure, 16 is a glass substrate, 17 is a signal electrode, 18 is a scanning electrode, and 19 is a pixel electrode.

Next, the operation will be explained.

In FIG. 1, light from a backlight 15 is converted into a uniform surface light source by a scattering plate 14, and a polarizing plate 11. The image is modulated by the liquid crystal panel 12 and displayed.

On the other hand, the light from the front of the liquid crystal panel 12 is reflected by a microscopic mirror 13 as shown in FIG. enables imaging of Micro reflector 13
suppresses bleeding between pixels on a regular LCD display,
In the case of an active matrix, it also serves as a black stripe provided to suppress the incidence of light into the TPT. In addition, since the micro-reflector 13 is oblique, the reflected light always travels toward the television camera 2o, so there is no effect on human vision. In the case of an active matrix display, the percentage of area that effectively contributes to display is 50
%, and conversely, the area in which the micro-reflector 13 can be placed is about 50% of the entire display. Therefore, microreflection! It is possible to image the subject M using 11113. Although the description has been made regarding a transmissive flat display, the present invention is not limited thereto, and the present invention can also be applied to a reflective type.

[Effects of the Invention J As explained above, the present invention provides a large number of micro-reflecting mirrors for obtaining reflected images for imaging a subject in front of the flat display by an imaging device in an area not directly involved in display inside the flat display. Therefore, it is possible to align the line of sight of those communicating between remote locations, eliminate the sense of discomfort that existed in the past, and enable natural meetings and discussions.

Also, compared to display/imaging devices with similar effects,
Since the display/imaging device of the present invention does not require additional parts such as lenses, the device can be made thinner.

Suitable for downsizing.
