`In
`television 1 can be used as is, but in a preferred
`embodiment, one wherein this rear projection television 1 is
`partially modified, as shown in FIG. 2, is used. That is to say,
`as shown in FIGS. 2 and 3, a rear projection television 11
`serving as a main display unit according to the present
`embodiment is disposed with a front face 3a of a rectangular
`screen 3, which serves as the image formation part, facing
`the interior of a room 14, at an opening 16 that is formed in a
`wall 15 of the room 14, in an ordinary residential or
`commercial building. The front face 3a of the screen 3,
`which is provided at the front (to the left in FIG. 2) of the
`cabinet 12 of such a rear projection television 11, is
`positioned forward of the front 12a of the cabinet 12 by a
`distance D1 (for example, D1 = 25 mm); this distance D1 is
`made greater than the distance D2 (for example, D2 = 10
`mm) between the front 6 of the cabinet and the front face 3a
`of the screen of the market available rear projection
`television 1 shown in FIG. 1. The cabinet 12 itself is
`disposed behind the wall 15 and cannot be seen from within
`the room 14; furthermore, as described above, the screen 3
`protrudes forward from the cabinet 12 so that the front face
`3a of the screen and the wall surface 15a in the room 14 are
`substantially flush. Reference numeral 17 [indicates] a
`support member (screen frame), which protrudes forward
`from the cabinet 12 and is rectangular as seen from the front,
`the back end of which is attached to the front 12a of the
`cabinet 12, and supports the screen 3 with an engagement
`part 18 at the front end thereof; this is normally made from a
`plastic or aluminum material. This support member 17 is

`[Claims]
`[Claim 1] A display device characterized by comprising: a
`main display unit disposed at an opening that is in formed a
`wall of a room in a building, with the front face of an image
`formation part facing the interior of the room; and a frame
`member, which is engaged on the main display unit,
`disposed at the periphery of the image formation part, so as
`to cover a gap between the main display unit and the edge
`of the opening.
`[Claim 2] The display device according to claim 1,
`characterized in that an engagement part is formed on the
`main display unit, and desired frame members can be
`exchanged on this engagement part.
`[Detailed Description of the Invention]
`[0001]
`[Field of Industrial Application] The present invention
`relates to a display device such as a rear projection
`television, and in particular relates to a display device that is
`structured so as to be housed at the interior of a wall.
`[0002]
`[Prior Art] Rear projection televisions as mentioned above
`have built-in CRTs for R (blue [sic]), G (green) and B (blue),
`and the colored light that is emitted from each of these CRTs
`irradiates the back face of a screen mounted in a cabinet so
`as to form a color image on the front face of the screen.
`Such rear projection
`televisions, or ordinary market
`available televisions that use a normal CRT, are normally
`used by placing them in the living room of an ordinary
`residence or in a viewing room in a commercial building.
`[0003]
`[Problems to Be Solved by the Invention] However, the
`aforementioned rear projection televisions and ordinary
`televisions alone take up their own space when set up in
`rooms, and the perceived presence of the main television
`unit is strongly felt. In particular, as the cabinets of the
`aforementioned rear projection televisions were normally
`large, they occupied a large amount of space when set up in
`a room, and thus the perceived presence thereof was even
`greater. Furthermore, there were problems in so much as
`large rear projection television devices were in the way, and
`made the room smaller, and in particular in cases such as
`that of an ordinary residence with small rooms, it was not
`possible to view them from more than a predetermined
`distance from the screen.
`the
`[0004] The presence of such cabinets reduced
`concentration of the viewer on the content of the images that
`were displayed on the screen, such that the presence of the
`cabinet itself had a negative impact, constituting what might
`be termed a noise factor. The present invention was made in
`order to solve such problems, and an object thereof is to
`produce a display device that can entirely eliminate the
`perceived presence of the cabinet.
`[0005] Furthermore, an object is to produce a display device
`that allows the frame member to be freely selected in
`keeping with the content of the image.
`[0006]
`[Means for Solving the Problems] The display device
`according to the present invention comprises: a main
`display unit disposed at an opening that is formed in a wall
`of a room in a building, with the front face of an image
`formation part facing the interior of the room; and a frame
`member, which is engaged on the main display unit,
`disposed at the periphery of the image formation part, so as
`to cover a gap between the main display unit and the edge
`of the opening.

`

`(3) JP-04-322579-A
`frame has been hung on the wall surface 15a, and to
`produce a comfortably harmonious feeling, without the
`design of the frame producing a discordant feeling with
`respect to the content of the image. Meanwhile, when a
`television broadcast is received, it is preferable to use a
`frame member 22 that is merely a frame, with which the
`perceived presence of the frame can be abstracted to as
`great an extent as possible.
`[0014] Note that, in order to operate this rear projection
`television 11, a portable controller 26 having an infrared
`emitter unit is placed within the room 14, and infrared
`signals are emitted from this controller 26. The emitted
`infrared signals pass through the speaker Saran net 20,
`whereafter they are received by an infrared receiver unit 27,
`which is installed facing forward in the vicinity of the speaker
`19, and command signals are output to the electronic
`components and optical components within the cabinet 12,
`from this infrared receiver unit 27. Consequently, colored
`light emitted from a CRT lens-block 28 is reflected by a
`reflector 29, and then irradiates the back face of the screen
`3, forming a color image on the front face 3a of the screen 3.
`[0015] Furthermore, with the present embodiment, the
`cabinet 12 is set up behind the wall 15, and therefore it is
`not necessary to provide decoration on this cabinet 12 itself,
`allowing for cost reductions in terms of the materials and the
`decoration for the cabinet 12. Further, safety can be
`improved by making this cabinet 12 out of a material having
`good fire resistance. Furthermore, when the rear projection
`television 11 is off and no image is formed on the screen 3,
`the frame member 22 (or the frame 24 or 25) on which
`decoration has been provided constitutes an effective part of
`the interior design of the room 14.
`[0016] Note that, in the embodiment described above, a
`case was shown in which the rear projection television 11
`served as the main display unit, but an ordinary television
`having a CRT may serve as the image formation part.
`Furthermore, the type of wall as well as the material therefor,
`the color thereof and the like may be freely chosen, and
`there are no restrictions on the location of the wall, such that
`opening can be provided at a desired location in the wall
`and the rear projection television 11 can be set up there.
`[0017]
`[Effects of the Invention] Because the present invention
`according to claim 1 is configured as described above, only
`the image formation part will be seen from the interior of the
`room, without the main display unit being seen at all, which
`eliminates the perceived presence of the main display unit,
`allowing only the necessary image to be produced, and
`because the gap between the main display unit and the
`opening in the wall is covered by the frame member, the gap
`is not exposed to the interior of the room.
`invention
`[0018] Furthermore, because
`the present
`according to claim 2 is configured as described above, it is
`possible to achieve harmony between the image and the
`frame member by freely selecting the frame member
`according to the content of the image on the image
`formation part.
`
`as thin and narrow as possible (for example, a width of 3
`mm). Thus, with the rear projection television 11 shown in
`FIG. 2, the screen 3 is positioned further forward than that of
`the rear projection television 1 shown in FIG. 1 by a distance
`(D1 – D2) (for example, 15 mm) and therefore the electronic
`components and optical components serving to form a clear
`color image on the front face 3a of this screen 3 are
`disposed so as to be shifted forward by the necessary
`distance (for example 15 mm).
`[0011] Furthermore, in the rear projection television 1 shown
`in FIG. 1, Saran net 7 for covering a speaker and support
`members 8a, 8b that support this Saran net 7 are provided
`below the front 6 of the cabinet 2, but in the rear projection
`television 11 shown in FIG. 2, such Saran net 7 and support
`members 8a, 8b are eliminated [sic]. In their place, as
`shown in FIG. 3, a speaker Saran net 20 is formed in the
`wall 15, in front of the speaker 19 that is mounted on the
`lower front of the cabinet 12, corresponding to the position
`of this speaker 19, whereby the sound that is generated by
`the speaker 19 passes through the speaker Saran net 20,
`and reaches the interior of the room 14.
`[0012] Further, in the present invention, a frame a member
`22 is disposed at the peripheral edge of the screen 3, which
`covers a gap 21 between the rear projection television 11
`and the edge of the opening 16 in the wall 15, this frame
`member 22 engaging on the rear projection television 11. As
`a more preferred mode for the present embodiment, an
`engagement part 23 is formed at the outer peripheral face of
`the support member 17, in the vicinity of the forward end
`thereof, which allows the frame member 22 to be replaced
`by way of engagement and disengagement, when the rear
`projection television 11 has been positioned by way of
`inserting the support member 17, which supports the screen
`3, into the opening 16 in the wall 15. This engagement part
`23 may have a flat surface but, preferably, a groove-like
`height differential is formed so that the frame member 22 will
`not accidentally fall off of this engagement part 23 but rather
`the frame member 22 can be held with a suitable force, and
`so that it can be mounted or dismounted with a single
`operation. Furthermore, this frame member may be fixed in
`place in an easily mountable and dismountable manner, by
`way of Velcro or screw members in positions that cannot be
`seen from within the room.
`[0013] It will be noted that, as shown in FIG. 3 and 4, the
`cabinet 12 of the rear projection television 11 is set up
`behind the wall 15, and therefore requires no decoration
`whatsoever, but ordinary decoration is provided on the
`support member 17 and the frame member 22, which are
`exposed to the interior of the room. In particular, it is
`possible to prepare multiple types of frame members 22 on
`which differing decoration is provided, such as providing a
`frame 24 that gives a heavy impression when still images
`such as pictures 100 or the like are [displayed] (FIG. 5) and
`providing a frame 25 that has a plain feel when other images
`(for example moving images such as a television broadcast)
`are [displayed] (FIG. 6), and to select the frame member 22
`with the most suitable decoration for the content of the
`image that is formed on the screen 3, and engage this on
`the engagement part 23 of the support member 17, allowing
`only the image on the screen 3 and the frame member 22 to
`be seen, while the cabinet 12 itself cannot be seen at all
`from the interior of the room 14. In particular, when a BGV
`videotape is used so as to form a still image such as
`scenery on the screen 3, it is possible to achieve an
`unexpected effect wherein it seems as if a picture having a
