[0001] The present application is related to the Japan Patent
Application No. 2007-238457, filed Sep. 13, 2007, the entire
disclosure of which is expressly incorporated by reference
herein.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to a display provided with a
front cabinet, and a display panel fixed to the front cabinet.
[0004] 2. Description of the Related Art
[0005] A known display displays images on a display panel having a
front surface exposed in a window formed in a front part of a
cabinet. The cabinet of the display includes a front cabinet,
namely, a front part of the cabinet, provided with the window, and
a rear cabinet, namely, a rear part of the cabinet. The display is
assembled by an assembling method including the steps of fixing the
display panel to the front cabinet with its front surface exposed
in the window, and fastening the rear cabinet to the front cabinet
with fixing members.
[0006] A conventional method of fixing the display panel to the
front cabinet uses fixing members. The same fixing members are used
for fixing each of display panels respectively having different
thicknesses. The fixing members are those specially for fixing
display panels to front cabinets, other than general fixing
members, such as screws and washers.
[0007] A technique disclosed in, for example, Japanese Unexamined
Patent Application Publication (JP-A) No. 1997-311319 (hereinafter

the wall, and fixes the wiring board to the wall. Washers are put
on screws, respectively, and screws are screwed into the members or
the bosses with the back surfaces of the washers in contact with
the display panel such that the washers presses the wiring board
fitted in the slits against the wall.
[0011] The Patent documents 1 to 3 have the following problems. All
the techniques disclosed in Patent documents 1 to 3 need fixing
members for fixing the display panel to the cabinet. Therefore,
those techniques need to assemble many parts requiring much
assembling work. The fixing members necessary for fixing the
display panel to the cabinet increase the cost
[0012] The technique disclosed in Patent document 4 is not a
technique for fixing a display panel to a cabinet.
BRIEF SUMMARY OF THE INVENTION
[0013] The present invention has been made in view of those
problems and it is therefore an object of the present invention to
provide a display including a front cabinet to which any one of
display panels respectively having different thicknesses can be
fixed without using other members.
[0014] A display in one aspect of the present invention having a
front cabinet provided with a substantially rectangular window in
which a front surface of a thin display panel disposed in the front
cabinet is substantially exposed,
[0015] a holding structure, including plurality of bosses with
axially threaded holes, with the plurality of bosses protruding
from a boundary of a display panel holding area on a back surface
of the front cabinet;
[0016] positioning ribs, protruding from the back surface of the
front cabinet so as to be in contact with a perimeter of a display
panel placed in the front cabinet to position the display panel in
the front cabinet; and
[0017] screwing members, with each screwing member having a
threaded part capable of being screwed into the threaded hole of
each boss of plurality of bosses, and a pressing part, extending
about the axis of the threaded part;
[0018] the plural of bosses of the holding structure are divided
into sets, each of the adjacently arranged bosses respectively
having different lengths respectively for display panels
respectively having different thicknesses,
[0019] a display panel is positioned in the front cabinet by the
positioning ribs,
[0020] the screwing members are screwed into the threaded holes of
the plurality of bosses of a length substantially equal to a
thickness of a display panel positioned in the front cabinet to
hold the display panel fixedly between the back surfaces of the
pressing parts of the screwing members and the back surface of the
front cabinet.
[0021] The present invention relates to the thus formed display in
which a thin display panel is disposed in the front cabinet with
its front surface exposed in the substantially rectangular window
of the front cabinet. This display includes: the holding structure
including plurality of bosses protruding from the boundary of the
panel holding area on the back surface of the front cabinet and
provided with axially threaded holes, respectively, the positioning
ribs protruding from the back surface of the front cabinet so as to
be in contact with the perimeter of a display panel placed in the
front cabinet to position the display panel in the front cabinet,
and the screwing members having threaded parts capable of being
screwed into the threaded holes of the bosses, respectively, and
the pressing parts extending about the axes of the threaded shanks,
respectively. The plurality of the bosses of the holding structure
are divided into sets each of the adjacently arranged bosses
respectively having different lengths respectively for display
panels respectively having different thicknesses.
[0022] A display panel can be fixedly held between the back
surfaces of the pressing parts of the screwing members and the back
surface of the front cabinet by positioning the display panel in
the front cabinet by the positioning ribs, screwing the screwing
members into the threaded holes of the bosses of the length
substantially equal to the thickness of the display panel disposed
in the front cabinet.
[0023] In other words, the display panel is fixed to the front
cabinet by the positioning ribs and the screwing members each
having the threaded part and the pressing part. Therefore, any
additional fixing members are not necessary when generally
available members, such as washers, are used as the pressing parts.
Thus the display can be formed by assembling a small number of
parts by less assembling work. Fixing members are not necessary and
hence the cost can be reduced accordingly.
[0024] As apparent from the foregoing description, according to the
present invention, the front cabinet can be used for fixedly
holding any one of display panels respectively having different
thicknesses.
[0025] Preferably, a support rib having a length substantially
equal to that of each of the bosses is formed near the boss, and
the screwing member is screwed into the threaded hole of the boss
such that the back surface of the pressing part of the screwing
member is held near the upper end of the rib. When the screwing
members are screwed into the threaded holes of the bosses to hold a
display panel between the back surfaces of the pressing parts and
the back surface of the front cabinet, parts, not in contact with
the display panel, of the pressing parts are held near the upper
ends of the support ribs, respectively. Thus, the back surfaces of
the pressing parts are substantially parallel to the back surfaces
of the display panel. Therefore, it is possible to prevent failure
in exerting force on the display panel by the back surfaces of the
pressing parts when the screwing members are screwed into the
threaded holes of the bosses, and the display panel can be surely
fixed to the front cabinet.
[0026] Preferably, each support rib has a T-shaped top surface.
[0027] Since the pressing parts rest on the T-shaped top surfaces
when the screwing members are screwed into the threaded holes of
the bosses, the screwing members can surely exert force through the
pressing parts on the display panel.
[0028] Preferably, the back surface of the pressing part of each
screwing member is formed such that high frictional force acts
between the back surface of the pressing part and the back surface
of the display panel. Since high frictional force acts between the
back surface of the pressing part and the back surface of the
display panel when the screwing member is screwed into the threaded
hole of the boss, it is possible to prevent failure in exerting
force on the display panel by the back surfaces of the pressing
parts when the screwing members are screwed into the threaded holes
of the bosses, and the display panel can be surely fixed to the
front cabinet.
[0029] According to another aspect of the present invention, the
display includes: a display panel having the shape of a thin box, a
wiring board, for giving received signals to the display panel and
supplying power to the display panel, attached to the back surface
of the display panel; a rear cabinet joined to the back end of the
front cabinet; and support ribs disposed near the bosses,
respectively, and each having a length substantially equal to that
of the boss adjacent thereto; wherein the pressing parts are
washers, each of the support ribs has a T-shaped top surface, the
back surface of the pressing part of the screwing member is
supported on the T-shaped top surface of the support rib when the
screwing member is screwed into the threaded hole of the boss, the
pressing part is provided in its back surface with projections
projecting from the back surface so that high frictional force may
act between the back surface of the pressing part and the display
panel.

DETAILED DESCRIPTION OF THE INVENTION
[0037] A preferred embodiment of the present invention and
modifications will be described with reference to the accompanying
drawings in the following order.
[0038] (1) Embodiment
[0039] (2) Modifications
Embodiment
[0040] A display 10 in a preferred embodiment according to the
present invention will be described with reference to the
accompanying drawings. FIG. 1 shows the display 10. The display 10
has a cabinet including a front cabinet 100 and a rear cabinet 70,
a display panel 90 for displaying images, and a wiring board 80 for
electrically controlling operations of the display 10.
[0041] The display panel 90 includes devices for displaying images.
A panel body that displays pictures and characters represented by
analog or digital signals is a principal component of the display
panel 90. In the present invention, display panel 90 includes other
devices for driving the panel body. Suppose that the panel body is
a liquid crystal panel. Then, those devices are a backlight unit
for illuminating the panel body from behind the panel body, a bezel
as a protective frame for protecting the panel body, a back frame
and such. The following description will be made on an assumption
that the panel body is a liquid crystal panel. However, the panel
body is not limited to a liquid crystal panel and may be, for
example, a plasma display panel (PDP) or a light-emitting diode
panel (LEDP).
[0042] FIG. 2 is a fragmentary sectional view in a vertical plane
of the display panel 90 fixed to the front cabinet 100. The display
panel 90 displays images represented by digital signals controlled
by the wiring board 80. As shown in FIG. 2, the display panel 90
has the shape of a thin box. As mentioned above, the display panel
90 includes a panel body 91, a backlight unit 92, a bezel 93, an
optical sheet 94, a positioning frame 95 and a back frame 96.
[0043] In the display panel 90, the optical sheet 94 disposed
behind the panel body 91, and the backlight unit 92 is disposed on
the back surface of the optical sheet 94. The panel body 91, the
optical sheet 94 and the backlight unit 92 are fixedly held by the
positioning frame 95 in a predetermined positional relation. The
panel body 91, the optical sheet 94 and the backlight unit 92 held
in the predetermined positional relation are covered with the bezel
93 from the front side and with the back frame 96 from the back
side. The panel body 91 displays images on its front surface on the
front side. The bezel 93 is a reinforcing frame for covering the
panel body 91 from the front side. The optical sheet 94 has a
function to absorb or reflect light in a predetermined wavelength
range in addition to a function to diffuse light emitted by the
backlight unit 92 to enhance brightness. The components of the
display panel 90 are fixed by, for example, fixing side parts
thereof with screws.
[0044] The front cabinet 100 is a front part of a cabinet. The
display panel 90 is fastened to the front panel with screwing
members 150. FIG. 3 is a rear view of the front cabinet 100. The
front cabinet 100 of the display 10 has the shape of a thin box
having one open end. The front cabinet 100 has a front wall
opposite the open end and provided with a substantially rectangular
window 110 in which the front surface of the display panel 90 is
exposed, positioning ribs 120 for positioning the display panel 90
in the front cabinet 90 with the front surface thereof exposed in
the window 110, a holding structure 130, for fixedly holding the
display panel 90 placed in the front cabinet 100, including plural
bosses 131a to 131x, and support ribs 140 on which screwing members
150, which will be described layer, screwed into threaded holes 132
of the bosses 131a to 131x rest. The back surface of the front
cabinet 100 is opposite the front surface of the same in which the
front surface of the display panel 90 is exposed. Preferably, the
holding structure 130 and the positioning ribs 120 are formed
integrally with the front cabinet 100.
[0045] In this embodiment, the four positioning ribs 120 are
arranged in each of the upper and the lower side of the front
cabinet 100 as shown in FIG. 3, and the two positioning ribs 120
are arranged in each of the right and the left side of the front
cabinet 100 as shown in FIG. 3. In the holding structure 130, the
eight bosses are arranged in each of the upper and the lower side
of the front cabinet 100, and the four ribs are arranged in the
right and the left side of the front cabinet 100. The bosses 131a
to 131x are disposed so as to lie near the perimeter of the display
panel 90 mounted on the front cabinet 100. The positioning ribs 120
are arranged such that the free ends thereof are in contact with
the perimeter of the display panel 90 mounted on the front cabinet
100.
[0046] The positioning ribs 120 positions the display panel 90 at a
predetermined position in the front cabinet 100. FIG. 4 is a view
of assistance in explaining the positioning rib 120 included in
this embodiment. In FIG. 4, the display panel 90 mounted on the
front cabinet 100 is indicated by dotted lines. Each positioning
rib 120 is a part rising from the back surface of the front cabinet
100 and having the shape of a thin plate. An inner part of a tip
part of the positioning rib 120 is cut to form a step 121. The
positioning rib 120 has an L-shape. The step 121 and an end surface
122 rising from the step 121 positions the display panel 90. More
concretely, a part of the front surface of the display panel 90 is
seated on the step 121, and a part of a side surface of the display
panel 90 is brought into contact with the end surface 122. Thus,
the display panel 90 is disposed on the back surface of the front
cabinet 100 with the side edges thereof in contact with the end
surfaces 122 of the positioning ribs 120.
[0047] The holding structure 130 holds the display panel 90 fixedly
in the front cabinet 100. FIG. 5 is a perspective view of
assistance in explaining the holding structure 130 included in this
embodiment. Referring to FIG. 5, the holding structure 130 has the
plural bosses 131a to 131x. The bosses 131a to 131x are cylindrical
parts rising from the back surface of the front cabinet 100 and are
provided with axial threaded holes 132, respectively. Screwing
members 150, which will be described later, are screwed into the
threaded holes 132, respectively. As shown in FIG. 3, the bosses
respectively having different lengths, such as the bosses 131i and
131j, are disposed contiguously. The sets each of the two bosses
respectively having different lengths are used for holding two
display panels respectively having different thicknesses,
respectively. The lengths of bosses are determined so as to be
suitable for holding the two display panels, respectively.
[0048] Desirably, the bosses 131a to 131x and the positioning ribs
120 are not disposed at the same positions, respectively, on the
back surface of the front cabinet 100 to avoid the breakage of the
bosses 131a to 131x due to the transmission of shocks exerted on
the positioning ribs 120 to the bosses 131a to 131x. For example, a
state where the boss 131a of the holding structure 130 and the
positioning rib 120 are at the same position is a state where the
boss 131a and the positioning rib 120 are on a two-dot chain line
AA' shown in FIG. 3 and the boss 131a and the positioning rib 120
are formed in a single member.
[0049] The support ribs 140 support the screwing members 150, which
will be described later, screwed into the threaded holes 132 of the
bosses 131a to 131x, respectively. As shown in FIG. 5, the support
ribs 140 are plate-shaped parts rising from the back surface of the
front cabinet 100. The respective lengths of the support ribs 140
are substantially equal to those of the adjacent ones of the bosses
131a to 131x, respectively. The support ribs 140 are combined with
the bosses 131a to 131x, respectively. Therefore, the support ribs
140 have lengths substantially equal to those of the adjacent ones
of the bosses 131a to 131x. Each of the support ribs 140 has a
T-shaped top surface (substantially T-shaped top surface). Although
the support ribs 140 and the bosses 131a to 131x respectively
adjacent to the support ribs 140 are integrated in parts,
respectively, the support ribs 140 and the bosses 131a to 131x may
be formed separately.
[0050] The screwing members 150 are screwed into the threaded holes
132 of the bosses 131a to 131x to fasten the display panel 90 to
the front cabinet 100. FIG. 6 is a perspective view of assistance
in explaining the screwing member 150. As shown in FIG. 6, the
screwing member 150 has a threaded shank 151 and a pressing part
152 extending about the axes of the threaded shank 151. In this
embodiment, the threaded shanks 151 are provided with screw threads
capable of being engaged in the threaded holes 132 of the bosses
131a to 131x, respectively, and the pressing parts 152 are thin,
tubular washers or the like. The screwing member 150 is formed by
passing the threaded shank 151 through the opening of the washer.
In this embodiment, the pressing part 152 is provided on its back
surface with projections 153 projecting in a direction of the
thickness of the pressing part 152.
[0051] The rear cabinet 70 is joined to the open rear end of the
front cabinet 100 to form a back part of the cabinet. The rear
cabinet 70 has the shape of a thin box having an open end. Joining
parts 71 that engage with the front cabinet 100 are formed
integrally with side walls of the rear cabinet 70.
[0052] The wiring board 80 controls received signals to display
images on the display panel 90. The wiring board 80 includes a
digital processing unit for controlling received signals, and a
power unit, such as a stabilized power unit, for supplying power to
the component parts. For example, the digital processing unit
includes a tuner, a front end unit, a decoder and an image
processing unit. The digital processing unit demodulates received,
broadcast television signals, and gives signals obtained by
demodulating the received, broadcast television signals to the
display panel 90. The display panel 90 obtains analog signals
through the digital-to-analog conversion of the received signals to
display images. The power unit stabilizes the voltage of power
received from an external power supply and supplies power of a
stabilized voltage to the display panel 90 and the wiring board
80.
[0053] A method of assembling the display of the present invention
will be described below.
[0054] The wiring board 80 is fastened to the back surface of the
display panel 90 with screws. As shown in FIG. 2 by way of example,
the wiring board 80 is fastened to a holding member, not shown,
formed on the back frame 96 with screws. The display panel 90 is
put in the front cabinet 100 such that the display surface of the
display panel 90 is exposed in the window 110 of the front cabinet
100. Then, the screwing members 150 are screwed into the threaded
holes 132 of the bosses 131a to 131x to fix the display panel 90 to
the front cabinet 100.
[0055] As shown in FIG. 2, the back surfaces of the pressing parts
152 of the screwing members 150 are in contact with the edge 93a of
the bezel 93 of the display panel 90 to press the display panel 90
against the back surface of the front cabinet 100. Thus, the
display panel 90 is held between the back surface of the front
cabinet 100 and the back surfaces of the pressing parts 152. In
this embodiment, a state where the display panel 90 is held between
the back surface of the front cabinet 100 and the back surfaces of
the pressing parts 152 is a state where the display panel 90 is
held between the steps 121 of the positioning ribs 120 and the back
surface of the pressing parts 152. Naturally, the positioning ribs
120 are omitted in some cases and display panel 90 does not
necessarily held in such a state.
[0056] In this display 10, either of the display panels 90
respectively having different thicknesses can be fixed to the front
cabinet 100. More concretely, the screwing members are screwed
selectively into the threaded holds 132 of suitable ones of the
bosses 131a to 131x selected according to the thickness of the
display panel 90. In this embodiment, the thickness of the display
panel 90 is a dimension between the front surface of the bezel 93
and the rear edge 93a (FIG. 2) of the bezel 93.
[0057] FIGS. 7A and 7B are views of assistance in explaining a
method of fixing display panels 90 respectively having different
thicknesses d1 and d2 (d1<d2) to the front cabinet 100. FIG. 7A
shows the display panel 90 having the thickness d1 to the front
cabinet 100 by using the bosses 131j. FIG. 7B shows the display
panel 90 having the thickness d2 to the front cabinet 100 by using
the bosses 131i. The bosses 131i are shorter than the bosses
131j.
[0058] In FIG. 7A, the height D1 of the boss 131j from the back
surface of the front cabinet 100 is substantially equal to the sum
of the height d'1 of the step 121 of the positioning rib 120 from
the back surface of the front cabinet 100 and the thickness d1 of
the display panel 90. Therefore, the back surfaces of the pressing
part 152 is brought into contact with the edge of the display panel
90 when the screwing member 150 is screwed into the threaded hole
132 of the boss 131j. Thus, the pressing part 152 presses the
display panel 90 against the back surface of the front cabinet 100
to hold the display panel 90 between the step 121 of the
positioning rib 120 and the pressing part 152 when the screwing
member 150 is screwed into the threaded holes 132 of the boss
131j.
[0059] A part, not in contact with the display panel 90, of the
pressing part 152 is in contact with the top surface of the support
rib 140. Thus, the pressing part 152 is held with its back surface
extended substantially parallel to the contact surface of the
display panel 90. Such contact surface means a surface to which the
back surface of the pressing part 152 contacts. Consequently,
frictional force acting on the back surface of the pressing part
152 can be effectively used. Preferably, the height D1 of the boss
131j and the support rib 140 is slightly shorter than the sum of
the height d'1 of the step 121 of the positioning rib 120 and the
thickness d1 of the display panel 90, namely, d1+d'1.
[0060] Similarly, as shown in FIG. 7B, the height D2 of the boss
131i from the back surface of the front cabinet 100 is
substantially equal to the sum of the height d'2 of the step 121 of
the positioning rib 120 and the thickness d2 of the display panel
90, namely, d2+d'2. Therefore, the back surfaces of the pressing
part 152 is brought into contact with the edge of the display panel
90 when the screwing member 150 is screwed into the threaded hole
132 of the boss 131i. Thus, the display panel 90 is held between
the step 121 of the positioning rib 120 and the pressing part 152
when the screwing member 150 is screwed into the threaded holes 132
of the boss 131i to fix the display panel 90 to the front cabinet
100. Either of the display panels 90 respectively having different
thicknesses can be fixed to the front cabinet 100 by selectively
using the bosses respectively having different lengths.
[0061] After fixing the display panel 90 to the front cabinet 100,
the respective open ends of the front cabinet 100 and the rear
cabinet 70 are joined and the front cabinet 100 and the rear
cabinet 70 are fastened together. More concretely, the joining
parts 71 in the side walls of the rear cabinet 70 are fitted in
openings, not shown, formed in the front cabinet 100 to join the
front cabinet 100 and the rear cabinet 70 correctly together. Then,
the front cabinet 100 and the rear cabinet 70 are fastened together
with screws to complete the cabinet of the display 10. The display
panel 90 and the wiring board 80 are held at predetermined
positions, respectively, in the cabinet.
[0062] Modifications
[0063] The present invention allows various modifications.
[0064] In the foregoing embodiment, the bosses 131a to 131x are
divided into sets each of the two bosses of different lengths. The
number of the bosses of each set is not limited to two, the number
of the bosses of each set may be changed according to the number of
display panels 90 respectively having different thicknesses.
[0065] The shape of the top surfaces of the support ribs 140 is not
limited to a T-shape; the top surfaces of the support ribs 140 may
be formed in any suitable shape, provided that the pressing parts
152 of the screwing members 150 can be held with their back
surfaces extended substantially parallel to the contact surface of
the display panel 90 when the screwing members 150 are screwed into
the threaded holes 132 of the bosses 131a to 131x.
[0066] The present invention is not limited in its practical
application to the preferred embodiment specifically described
herein and the parts of the embodiment may be replaced by suitable
parts and the combinations of the same may be properly changed.
[0067] The parts of the foregoing embodiment may be replaced with
parts of the know techniques capable of replacing the parts of the
foregoing embodiment, and combinations of those parts may be
changed.
[0068] The parts and combinations of the foregoing embodiment may
be changed for those thought to be capable of replacing the parts
and combinations of the foregoing embodiment by persons skilled in
the art.
[0069] While the invention has been particularly shown and
described with respect to preferred embodiments thereof, it should
be understood by persons skilled in the art that the foregoing and
other changes in form and detail may be made therein without
departing from the spirit and scope of the invention as defined in
the appended claims.
