[0003]
The display device described in Patent Document 1 can be set to be switched between a display
state in which a normal image is displayed and a display state in which an image inverted
horizontally is displayed on the front side and the back side. Even when viewed from either side,
it is possible to obtain a normal image.
This image inversion function allows, for example, a normal image not to invert characters or the
like from either the front or back surface of the liquid crystal panel by making it possible to
attach a reflector and a backlight from either side of the liquid crystal panel. Make it possible to
look at it.
Furthermore, this image inverting function makes it possible to display on the screen an image
that is horizontally inverted when viewing an image through a mirror to a customer in various
places including a barber.
[0004]
In addition, as a similar image inversion function, a technique is also proposed in which the
device is hung upside down in various places such as a school classroom or a karaoke place, and
an image vertically and horizontally reversed is displayed on the screen when viewing by a
viewer. It is done. Furthermore, there is also a technology for projecting an image corresponding
to the display screen on the screen even when the display screen is rotated 90 degrees left /
right as well as vertically / horizontally flipped the display screen.
[0005]
On the other hand, with regard to image display and audio output in an image display device, a
technology has been proposed in which a transparent speaker is attached to the front of the
display to make the entire display device compact (for example, described in Patent Document 2).
Patent Document 2 discloses a flat panel display of liquid crystal or CRT mounted with a
translucent flat speaker, and the appearance thereof is, as shown in FIG. 2, plural on the front
surface of the display 10 of the display unit 1. The flat speakers 11a to 11i are mounted.

The display device 1 illustrated here has nine transparent flat speakers mounted on the front
face of the display 10 so that the display surface is divided into nine vertically and horizontally,
but the number of speakers is not limited to nine, and is further increased You may also reduce
it. In the display device described in Patent Document 2, it is an object to emit different sounds
from the speakers 11a to 11i at the top, bottom, left, and right to bring about an effect of
increasing the sense of reality. For example, when a car crosses a screen, a flat speaker that emits
a sound can also be switched one after another in accordance with the movement of the car to
increase the realism of the sound.
[0007]
In addition, even if multi-channel audio signals based on the use of a plurality of transparent
speakers are input, reproduction is possible without being limited to the number of transparent
speakers, and reproduction is possible without losing the sense of reality as much as possible. An
information display apparatus with a transparent speaker has also been proposed (see, for
example, Patent Document 3). In the display device described in Patent Document 3, for example,
when software (for example, DVD software) including data is reproduced, an audio signal of the
digital audio interface standard is input to the DI terminal of the external input, and the
conversion table is internally provided. The number of channels of the input audio signal is
determined, and the number of channels is converted or not converted on the basis of the
determined number of channels and the number-of-channels information of the apparatus
internally provided. As described above, in the display device described in Patent Document 3, a
plurality of transparent speakers are disposed on the display surface so as to divide the display
surface, and the information with the transparent speaker capable of displaying information and
generating sound is provided. The display device is provided with means for correlating the input
channel in the speaker control information of the input signal with the device channel of the
