Description
[0001] The present application is a Divisional Application of
application Ser. No. 11/984,079 filed Nov. 13, 2007, which is a
Divisional Application of application Ser. No. 10/730,031 filed

2002-357617 and No. 2003-356388, the disclosures of which are
incorporated herein by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] This invention relates to the structure of flat display
apparatuses.
[0004] 2. Description of the Related Art
[0005] A flat display apparatus is equipped with a slim, flat
display panel, such as a plasma display panel (hereinafter referred
to as "PDP"), a field emission display panel (hereinafter referred
to as "FED"), and the like.
[0006] For example, the PDP is structured such that a pair of front
and back substrates are placed opposite in parallel to each other
with a discharge space in between and the periphery of the
discharge space is sealed.
[0007] More specifically, a reflection-type AC PDP has a plurality
of row electrode pairs formed on the inner surface of the front
substrate for the creation of a surface discharge (display
discharge), and a dielectric layer covering the row electrode
pairs. Further, on the inner surface of the back substrate facing
the front substrate, a plurality of column electrodes are arranged
in a direction at right angles to the row electrode pairs for the
creation of a selection discharge between the column electrode and
one row electrode in each row electrode pair, and a column
electrode protective layer covers the column electrodes. Between
the front substrate and the back substrate, a partition wall is
formed for partitioning the discharge space into discharge cells,
and phosphor layers of the three primary colors (i.e. red, green
and blue colors) are respectively formed in all the discharge cells
with the red, green and blue colors arranged in order.
[0008] FIG. 1 is a sectional side view illustrating a conventional
flat display apparatus with a flat display panel such as the
foregoing PDP mounted.
[0009] The conventional display apparatus has a flat display panel
3 which is fixed by an adhesive sheet 4 to the front surface (the
upward surface in FIG. 1) of a chassis 2 seated forward of a rear
case 1.
[0010] A frame 5 is attached to the front peripheral edge of the
chassis 2 and surrounds the flat display panel 3. The frame 5 has
an inner flange 5A formed in its front end. A front filter (panel
protective plate) 7 is mounted on a gasket 6 placed on the front
face of the inner flange 5A, and secured by a fitting 8.
[0011] FIG. 1 shows a front case 9 of the display apparatus.
[0012] FIG. 2 is a schematic side view illustrating the structure
of the front filter (panel protective plate) 7 of the display
apparatus.
[0013] In FIG. 2, the front filter (panel protective plate) 7 is
constructed of an electromagnetic-wave blocking layer (conductive
mesh) 7B formed on a glass substrate 7A; an antireflective layer 7C
formed on the electromagnetic-wave blocking layer 7B; and an
infrared-radiation absorbing and color-tone correcting layer 7D
formed on the back surface of the glass substrate 7A.
[0014] Such a conventional flat display apparatus is described in
Japanese Patent Laid-open application No. Hei. 11-219122.
[0015] As described hitherto, conventional flat display apparatuses
have a front filter (panel protective plate) placed forward of the
flat display panel. The front filter is structured such that a film
for preventing the reflection of ambient light and films for
blocking electromagnetic waves and infrared radiation generated
from the flat display panel are attached to a glass substrate. This
structure makes the front filter very expensive. Therefore the
conventional flat display apparatuses have the problem of increased
production costs.
SUMMARY OF THE INVENTION
[0016] It is an object of the present invention to solve the
problem associated with the conventional flat display apparatuses
as described above.
[0017] More specifically, an object of the present invention is to
provide a flat display apparatus capable of reducing production
costs.
[0018] To attain the object, the present invention provides a flat
display apparatus having a flat display panel. The flat display
apparatus has the feature of including a protective sheet attached
to the display screen surface of the flat display panel.
[0019] With the flat display apparatus according to the present
invention, the protective sheet is attached integrally to the
display surface of the flat display panel. Hence the elimination of
the conventional need for providing, independently of the flat
display panel, a protective panel for protecting the display
surface of the flat display panel is achieved, and therefore a
reduction in the number of parts and a simplification in the
structure for supporting a flat display panel becomes possible,
thus reducing production costs.
[0020] These and other objects and features of the present
invention will become more apparent from the following detailed
description with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0030] Preferred embodiments according to the present invention
will be described below in detail with reference to the
accompanying drawings.
[0031] FIG. 3 is a sectional side view illustrating a first
embodiment of the flat display apparatus according to the present
invention.
[0032] In FIG. 3 the same structural components as those in the
conventional apparatus described in FIG. 1 are designated by the
same reference numerals as those in FIG. 1.
[0033] The flat display apparatus in the first embodiment has a
flat display panel 3 supported on a chassis 2 by means of an
elastic sheet 14. The elastic sheet 14 is formed of a foam material
such as foam rubber of a 30 or less degrees hardness which is
capable of absorbing the distortion occurring when mounting and the
heat dissipated. To the display screen surface of the flat display
panel 3, an optical filter 17 is attached as a protective
sheet.
[0034] As schematically illustrated in FIG. 4, the optical filter
17 is formed by laminating an infrared-radiation absorbing and
color-tone correcting sheet 17B on an electromagnetic-wave blocking
sheet 17A, and further laminating an ambient-light antireflective
sheet 17C on the infrared-radiation absorbing and color-tone
correcting sheet 17B.
[0035] The length and width dimensions of the infrared-radiation
absorbing and color-tone correcting sheet 175 and the ambient-light
antireflective sheet 17C are somewhat smaller than those of the
electromagnetic-wave blocking sheet 17A. As illustrated in FIG. 5,
the peripheral edge of the electromagnetic-wave blocking sheet 17A
projects outward from the outer edge of the infrared-radiation
absorbing and color-tone correcting sheet 175 and ambient-light
antireflective sheet 17C, so that the metal pattern layer of the
electromagnetic-wave blocking sheet 17A is exposed to form an earth
connecting part as will be described later.
[0036] The optical filter 17 is attached directly to the flat
display panel 3 by adjoining the electromagnetic-wave blocking
sheet 17A to the display panel 3 by use of a filter-laminating
adhesive material 18.
[0037] The filter-laminating adhesive material 18 used for
attaching the optical filter 17 to the flat display panel 3 is made
of an acrylic-type or a silicon-type transparent material and has a
refractive index differing by 0.2 or less from the refractive index
or each of the refractive indexes of one or both of the optical
filter 17 and the substrate (the front glass substrate in PDPs)
constituting the display screen of the flat display panel 3, for
example, it has a refractive index ranging from 1.4 to 1.6.
[0038] Further, the filter-laminating adhesive material 18 used has
an adhesive strength of 3 kgf/inch or less when being vertically
detached.
[0039] The optical filter 17 with the filter laminating adhesive
material 18 is designed to be greater than or equal to 0.5 mm
thick.
[0040] The flat display panel 3 having the optical filter 17
attached to the display side surface is supported on a chassis 2. A
frame 15 is attached to the front-face peripheral edge of the
chassis 2 and has an inner flange 15A formed in its front end. The
inner flange 15A makes contact with an electrically-conductive
gasket 16 adjoining the area of the optical filter 17 in which the
electromagnetic-wave blocking sheet 17A is exposed, so as to
sandwich the gasket 16 between itself and the optical filter 17,
thereby clamping the flat display panel 3 to the chassis 2.
[0041] In place of the gasket, a spring member may be used.
[0042] Reference numeral 9 in FIG. 3 denotes a front case of the
display apparatus.
[0043] Because the optical filter 17 is integrally attached to the
display screen surface of the flat display panel 3, the flat
display apparatus according to the present invention does not need
a protective panel provided independently of the flat display panel
3 for protecting the display screen surface of the flat display
panel 3 as in the conventional techniques, so that the number of
parts is decreased and the supporting structure for the flat
display panel 3 is simplified to make low costs of production
possible.
[0044] Further, the flat display apparatus is designed such that
the optical filter 17 is attached directly to the display surface
of the flat display panel 3, and the refractive index of the filter
laminating adhesive material 18 used for attaching the optical
filter 17 is determined to differ by 0.2 or less from the
refractive index of the optical filter 17 or the substrate which
constitutes the display surface of the flat display panel 3, for
example in a range of from 1.4 to 1.6 so as to be approximately
equal to the refractive index of the glass substrate constituting
part of the flat display panel 3. This design eliminates the
reflection (about 8 percent) of the emitted light from the flat
display panel 3 which occurs due to an air space produced between a
flat display panel and a protective panel in the conventional
display apparatuses, thereby making possible to improve the
brightness and to prevent the contrast deterioration caused by the
rebounding of the reflected light to the non-light emission area of
the display panel.
[0045] More specifically, in the conventional display apparatuses
having an air space produced between the flat display panel and the
protective panel, generally, a little over 8 percent of the light
generated in the flat display panel reflects off the interfaces of
the flat display panel and protective panel to the air space and
returns to the inside of the panel. At this point, the returning
light is diffusely reflected light, and therefore it may illuminate
a not-light emission section adjacent to the light emission section
of the panel.
[0046] PDPs, in particular, include a phosphor layer formed in the
panel. The reflectance of the phosphor layer is the order of 30
percent, and therefore the phosphor layer reflects the returning
light (i.e. the reflected light from the interface of the flat
display panel or the protective panel). Because of this reflect
ion, it appears that light emission is caused from the not-light
emission section as well as the light emission section. Hence the
outline of the light emission section is blurred, leading to a risk
of losing the vigor and quality of an image to be displayed.
[0047] Further, recently, for the flat display panels, attempt has
been made to reduce the black luminance, but the reflection of the
returning light as described above may affect the reducing
effectiveness of the black luminance to decrease the reducing
effectiveness.
[0048] In the aforementioned flat display apparatus, the interfaces
of the flat display panel 3 and the optical filter 17 are attached
to each other by the filter laminating adhesive material 18 having
the refractive index differing by 0.2 or less from the refractive
index of the flat display panel 3 and optical filter 17. For this
reason, the reflection of light off the interfaces is suppressed,
leading to the prevention of loss of vigor and quality of an image,
and also the prevention of a decrease in the reducing effectiveness
of the black luminance in regard to the flat display panels
attempted to reduce the black luminance.
[0049] For a further increase in the foregoing effectiveness of
preventing lowering in the vigor and quality of an image and of
preventing a decrease in a reduction ratio of the black luminance,
when the flat display panel 3 is a PDP, the driving control is
performed on a discharge, e.g. a decrease in the intensity of a
discharge, a reduction in the number of discharges generated, and
the like, such that a luminance of 1 cdm.sup.2 or less is provided
by a discharge (e.g. a preliminary discharge such as a reset
discharge, a priming discharge, an addressing discharge and the
like which are caused without having direct bearing on the
displaying) except the display discharge for light emission for
forming an image.
[0050] Further, the foregoing flat display apparatus uses, for the
filter-laminating adhesive material 18, a material of an
acrylic-type or a silicon-type having an adhesive strength of 3
kgf/inch or less when being vertically detached, to make it
possible to separate the flat display panel 3 and the optical
filter 17 for repair without damaging the bases of the flat display
panel 3 and the optical filter 17.
[0051] Still further, the determination of a 0.5 or more mm
thickness for the optical filter 17 including the filter-laminating
adhesive material 18 makes it possible to maintain a shock
absorbing property against a shock from the outside, and to prevent
fracture of the flat display panel.
[0052] Yet further, the lamination of the optical filter 17 with
the electromagnetic-wave blocking sheet 17A side located adjacent
to the flat display panel 3 results in provision of a relatively
stable shield member interposed between the flat display panel 3
and the infrared-radiation absorbing and color-tone correcting
sheet 17B, which includes dyes tending to suffer degradation from
heat or light. This interposition makes possible to lessen the
effect of the heat and light produced from the flat display panel
upon the infrared-radiation absorbing and color-tone correcting
sheet 17B.
[0053] Note that by providing a transmittance-reducing component
between the electromagnetic-wave blocking sheet 17A and the flat
display panel 3, a relaxation of the acceptable standard of
appearance relating to irregular blackening of the
electromagnetic-wave blocking sheet 17A and the like becomes
possible.
[0054] Further, the electromagnetic-wave blocking sheet 17A of the
optical filter 17 is formed somewhat larger than the
infrared-radiation absorbing and color-tone correcting sheet 17B
and ambient light antireflective sheet 17C which are to be
laminated on the electromagnetic-wave blocking sheet 17A. Therefore
the outer peripheral edge of the electromagnetic-wave blocking
sheet 17A projects beyond the outer periphery of the
infrared-radiation absorbing and color-tone correcting sheet 17B
and ambient light antireflective sheet 17C. Thus, it is possible to
facilitate connecting the electromagnetic-wave blocking sheet 17A
to an earth.
[0055] Further, the flat display apparatus according to the present
invention is capable of absorbing and lessening an impact force
exerted from the outside, due to the use of a foam material having
a hardness of 30 or less degrees for the elastic sheet 14 which is
provided for supporting the flat display panel 3 on the chassis
2.
[0056] Still further, in the flat display apparatus according to
the present invention, the flat display panel 3 is fixed on the
chassis 2 by being clamped between the frame 15 and the chassis 2
by use of interposition of the conductive gasket 16 without the use
of an adhesive sheet as in the conventional techniques.
Accordingly, the recycling and replacement work on the flat display
panel become much easier as compared with a conventional case when
the flat display panel 3 is fixed by use of an adhesive sheet.
[0057] In addition, the earth connecting part formed on the outer
edge of the optical filter 17 is supported between the conductive
gasket 16 and the optical filter 17. Thus, the fixing of the
display panel by the frame 15 and the electric connection with the
optical filter 17 are achieved simultaneously. This makes possible
a decrease in the number of parts, resulting in the possibility of
reducing production costs.
[0058] Moreover, in the first embodiment, the order of lamination
of the electromagnetic-wave blocking sheet, the infrared-radiation
absorbing and color-tone correcting sheet, and the ambient light
antireflective sheet in the optical filter is not limited to that
illustrated in FIG. 4. For example, the electromagnetic-wave
blocking sheet and the ambient light antireflective sheet may be
laminated in order onto the infrared-radiation absorbing and
color-tone correcting sheet.
[0059] FIG. 3 illustrates the structure when the panel 3 is clamped
between the frame 15 and the chassis 2 with the interposition of
the conductive gasket 16 to be mounted on the chassis 2. However,
an adhesive layer may be provided on each of the front and back
surfaces of the foam material forming the elastic sheet 14, and the
panel may be fixed mounted on the chassis by means of the adhesive
layers.
[0060] FIG. 6 is a plan view illustrating another structure of an
optical filter in a second embodiment.
[0061] An optical filter 27 in illustrated in FIG. 6 includes an
electromagnetic-wave blocking sheet 27A having the width in the
vertical direction greater than the vertical width of an
infrared-radiation absorbing and color-tone correcting sheet 27B
and an ambient light antireflective sheet 27C. Both the upper end
and lower end of the electromagnetic-wave blocking sheet 27A
project beyond the infrared-radiation absorbing and color-tone
correcting sheet 27B and ambient light antireflective sheet 27C.
However, the electromagnetic-wave blocking sheet 27A has the same
width in the horizontal direction as that of the infrared-radiation
absorbing and color-tone correcting sheet 27B and the ambient light
antireflective sheet 27C.
[0062] The infrared-radiation absorbing and color-tone correcting
sheet 27B and ambient light antireflective sheet 27C have aligned
recesses 27Ba and 27Ca formed in the same position in the central
portion of each of the right and left ends, so that an end part of
the electromagnetic-wave blocking sheet 27A is exposed inside each
set of the recesses 27Ba, 27Ca.
[0063] The optical filter 27 is connected to an earth at the upper
and lower projecting end portions a1 of the electromagnetic-wave
blocking sheet 27A and at portions b1 exposed inside the sets of
recesses 27Ba, 27Ca.
[0064] The structure of the optical filter 27 of the flat display
apparatus as described above enables the following manufacturing
method: as indicated by the broken line in FIG. 6, the
electromagnetic-wave blocking sheet 27A, the infrared-radiation
absorbing and color-tone correcting sheet 27B and the ambient light
antireflective sheet 27C are formed in a strip shape and rolled up
in a scroll shape; and the scrolled sheets 27A, 27B and 27C are
then unrolled in the strip form and laminated to one another (at
this stage, the strip-form infrared-radiation absorbing and
color-tone correcting sheet 27B and ambient light antireflective
sheet 27C have already undergone the punching process for forming
the recesses 27Ba and 27Ca). The adoption of this manufacturing
method makes it possible to significantly reduce the manufacturing
costs for the optical filter 27.
[0065] In the structure illustrated in FIG. 6, the two sets of
recesses 27Ba, 27Ca are formed respectively in the right and left
ends of the laminated infrared-radiation absorbing and color-tone
correcting sheet 27B and ambient light antireflective sheet 27C.
However, a set of recesses 27Ba, 27Ca may be formed in a single
position, or alternatively three or more sets of recesses 27Ba,
27Ca may be formed.
[0066] FIG. 7 is a plan view illustrating yet another structure of
an optical filter in a third embodiment.
[0067] In the optical filter 37 illustrated in FIG. 7, an
electromagnetic-wave blocking sheet 37A has the same width in the
vertical direction as the vertical width of an infrared-radiation
absorbing and color-tone correcting sheet 37B and an ambient light
antireflective sheet 37C. However, the electromagnetic-wave
blocking sheet 37A has the width in the horizontal direction
greater than the horizontal width of the infrared-radiation
absorbing and color-tone correcting sheet 37B and the ambient light
antireflective sheet 37C. Each of the right and left ends of the
electromagnetic-wave blocking sheet 37A projects beyond the
infrared-radiation absorbing and color-tone correcting sheet 37B
and the ambient light antireflective sheet 37C.
[0068] The infrared-radiation absorbing and color-tone correcting
sheet 37B and the ambient light antireflective sheet 37C have
aligned sets of recesses 37Ba, 37Ca formed in their upper and lower
ends. An end part of the electromagnetic-wave blocking sheet 37A is
exposed inside each set of the recesses 37Ba, 37Ca.
[0069] In the structure illustrated in FIG. 7, the two sets of
recesses 37Ba, 37Ca are formed on each of the upper and lower ends
of the laminated infrared-radiation absorbing and color-tone
correcting sheet 37B and ambient light antireflective sheet 37C.
However, a set of recesses 37Ba, 37Ca, or alternatively three or
more sets of recesses 37Ba, 37Ca may be formed in each of the upper
and lower ends.
[0070] The optical filter 37 is connected to an earth at portions
a2 of the electromagnetic-wave blocking sheet 37A exposed inside
the recesses 37Ba, 37Ca and at right and left projecting end
portions b2 of the electromagnetic-wave blocking sheet 37A.
[0071] FIGS. 8 and 9 are a plane view and a side view illustrating
still another structure of an optical filter in a fourth
embodiment.
[0072] As in the case of the optical filter 17 in the first
embodiment, the optical filter 47 in the fourth embodiment has an
electromagnetic-wave blocking sheet 47A having vertical and
horizontal dimensions somewhat greater than those of an
infrared-radiation absorbing and color-tone correcting sheet 47B
and an ambient light antireflective sheet 47C. Therefore, the
peripheral end of the electromagnetic-wave blocking sheet 47A
projects beyond the outer periphery of the infrared-radiation
absorbing and color-tone correcting sheet 47B and the ambient light
antireflective sheet 47C, so that the metal pattern layer of the
electromagnetic-wave blocking sheet 47A is exposed to form an earth
connecting part s.
[0073] Further, on the surface of the electromagnetic-wave blocking
sheet 47A of the optical filter 47, a black metal film or
blacking-treated coating 47D is provided, and therefore the earth
connecting part s formed on the outer peripheral end portion of the
electromagnetic-wave blocking sheet 47A takes the so-called
full-face electrode form.
[0074] An even number of registration marks M are formed in
selected positions of the earth connecting part s for the
lamination of the optical filter 47 and the flat display panel
(FIG. 8 shows two registration marks M in the lower corners of the
optical filter 47, as an example).
[0075] The registration mark M is formed by punching a
circle-shaped or a cross-shaped hole, for example, in the
electromagnetic-wave blocking sheet 47A.
[0076] Thus, due to the black coating 47D formed on the
electromagnetic-wave blocking sheet 47A, the optical filter 47
illustrated in FIGS. 8 and 9 is capable of suppressing the
reflection of ambient light from the electromagnetic-wave blocking
sheet 47A to make it possible to improve the contrast of an image
to be displayed.
[0077] The provision of the registration marks Mon the optical
filter 47 makes possible easy and precise registration when the
optical filter 47 is laminated and attached to the flat display
panel by use of image-processing techniques or the like in the
manufacturing process.
[0078] A generic concept of the flat display apparatus in the
foregoing embodiment is a flat display apparatus including a flat
display panel and a protective sheet attached to the display screen
surface of the flat display panel.
[0079] With a flat display apparatus based on the generic concept,
the protective sheet is attached integrally to the display surface
of the flat display panel. Hence the elimination of the
conventional need for providing, independently of the flat display
panel, a protective panel for protecting the display surface of the
flat display panel is achieved, and therefore a reduction in the
number of parts and a simplification in structure for supporting a
flat display panel becomes possible, thus achieving low costs of
production.
[0080] The terms and description used herein are set forth by way
of illustration only and are not meant as limitations. Those
skilled in the art will recognize that numerous variations are
possible within the spirit and scope of the invention as defined in
the following claims.
