DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The above-mentioned and other technical contents, features, and
effects of this disclosure will be clearly presented from the
following detailed description of ten embodiments in coordination
with the reference drawings. Through description of the concrete
implementation method, the technical means employed and the
effectiveness to achieve the predetermined purposes of the present
disclosure will be thoroughly and concretely understood. However,
the enclosed drawings are used for reference and description only,
and are not used for limiting the present disclosure.
Before this disclosure is described in detail, it should be noted
that, in the following description, similar elements are designated
by the same reference numerals.
Referring to FIGS. 1 and 2, a liquid crystal display device 100
according to the first embodiment of the present disclosure is
adapted to be applied to a notebook computer as an example for
illustration, and is shown to comprise a support frame 1, a
backlight module 2 and a liquid crystal display panel 3.
As shown in FIGS. 2 and 3, the support frame 1 includes a bottom
wall 11, and a main surrounding wall 12 extending upwardly from and
formed integrally as one piece with the bottom wall 11. The bottom
wall 11 and the main surrounding wall 12 cooperatively define a
receiving space 13. The bottom wall 11 includes a first support 111
disposed in the receiving space 13. The main surrounding wall 12
includes a second support 121 disposed in the receiving space 13
and spacedly above the first support 111. The backlight module 2 is
supported on the first support 111. The liquid crystal display
panel 3 is supported on the second support 121 so that the liquid
crystal display panel 3 is positioned above the backlight module 2.
Through the integrally formed one-piece support frame 1 that can
accommodate simultaneously the backlight module 2 and the liquid
crystal display panel 3, the number of components of the liquid
crystal display device 100 can be reduced so that the liquid
crystal display device 100 has a simple structure. Because of this,
the assembly time and the manufacturing costs thereof can be
reduced. Further, accumulated tolerance of the components can also
be reduced.
A detailed structure of the liquid crystal display device 100 will
be described hereinbelow.
With reference to FIGS. 2 and 3, the backlight module 2 includes a
reflective plate 21, a light guide plate 22 stacked above the
reflective plate 21, and an optical film layer 23 stacked above the
light guide plate 22. The optical film layer 23 includes a lower
diffusion plate, a first prism plate, a second prism plate, and an
upper diffusion plate stacked one above the other. Since the
function of each optical film of the optical film layer 23 is well
known in the art, a detailed description thereof is dispensed
herewith. Further, the assembly of the optical film layer 23 is not
limited to the aforesaid disclosure. In this embodiment, the first
support 111 is formed on a top face of the bottom wall 11. The
second support 121 is formed on and extends along the entire length
of a top face of the main surrounding wall 12. Each of the first
and second supports 111, 121 has a horizontal support face. Because
the reflective plate 21 abuts against the first support 111 and the
liquid crystal display panel 3 abuts against the second support
121, the backlight module 2 and the liquid crystal display panel 3
will not be slanting relative to the support frame when assembled
thereon. Further, because the integrally formed one-piece support
frame 1 can simultaneously accommodate the backlight module 2 and
the liquid crystal display panel 3, the accumulated tolerance among
the components of the backlight module 2 and the liquid crystal
display panel 3 can be reduced.
The support frame 1 is made by injection molding a plastic
material. The main surrounding wall 12 further includes an annular
projection 122 projecting upwardly from the second support 121. The
liquid crystal display device 100 further comprises a positioning
element 4 in the form of a frame. The positioning element 4 covers
the main surrounding wall 12, and abuts against the projection 122
and the liquid crystal display panel 3. The positioning element 4
is fixed to the projection 122 and the liquid crystal display panel
3 by using adhesive or a screw fastening method. Through this, the
liquid crystal display panel 3 can be stably positioned to the main
surrounding wall 12. The positioning element 4 can be made of
Mylar, aluminum foil, or metal. In this embodiment, the positioning
element 4 is made of metal so as to provide an anti-EMI
(anti-electromagnetic interference) effect.
The support frame 1 further includes an auxiliary surrounding wall
14 extending upwardly and integrally from an outer periphery of the
bottom wall 11 and surrounding an outer periphery of the main
surrounding wall 12. The liquid crystal display device 100 further
comprises an upper casing 5 covering a periphery of the liquid
crystal display panel 3. The upper casing 5 is made by injection
molding a plastic material. The upper casing 5 has an upper wall 54
formed with an opening 51 for exposure of the liquid crystal
display panel 3, and an outer peripheral wall 52 extending
downwardly from an outer periphery of the upper wall 54. The outer
peripheral wall 52 is connected to the auxiliary surrounding wall
14 by using a hook-and-groove interlocking means or a screw
fastening method. Through such a connection, the upper casing 5 can
be stably fixed to the support frame 1. It should be noted that the
upper casing 5 of this embodiment may be configured as that shown
in FIG. 4. That is, the upper casing 5' is formed integrally as one
piece with the positioning element 4 shown in FIG. 2. The upper
casing 5' can similarly achieve the effect made by the upper casing
5 and the positioning element 4. Thus, the number of components of
the liquid crystal display device 100 can be further reduced.
FIG. 5 is a fragmentary sectional view of this embodiment taken
along line V-V of FIG. 1. As shown in FIG. 5, the main surrounding
wall 12 is recessed to form a cavity 123 that is spacedly below the
second support 121. The backlight module 2 further includes a
light-emitting unit 24 disposed in the cavity 123 and supplying
light to the light guide plate 22. Concretely speaking, the light
guide plate 22 has a lateral side 221, and a top side 222 connected
to a top end of the lateral side 221. The light-emitting unit 24
includes a flexible circuit board 241 disposed on the top side 222
of the light guide plate 22, and a light-emitting diode 242
disposed on a bottom side of the flexible circuit board 241 and
corresponding in position to the lateral side 221 of the light
guide plate 22. Through this configuration, when the support frame
1 is deformed caused by an external force, the light-emitting unit
24 can be prevented from being displaced, so that light generated
by the light-emitting diode 242 can be uniformly emitted to the
light guide plate 22 through the lateral side 221 thereof.
Further, the liquid crystal display device further comprises an
adhesive piece 61. The adhesive piece 61 is configured as a
double-sided adhesive tape adhered to and disposed between the top
side 222 of the light guide plate 22 and the bottom side of the
flexible circuit board 241, so that the flexible circuit board 241
can be stably positioned to the top side 222 of the light guide
plate 22.
Referring to FIG. 6, a liquid crystal display device 110 according
to the second embodiment of this disclosure has an overall
structure similar to that of the first embodiment. However, in this
embodiment, the light guide plate 22 further has a bottom side 223
connected to a bottom end of the lateral side 221, the flexible
circuit board 241 abuts against the first support 111, and the
light-emitting diode 242 is disposed on a top side of the flexible
circuit board 241 and corresponds in position to the lateral side
221 of the light guide plate 22. The adhesive piece 61 is adhered
to and disposed between the bottom side 223 of the light guide
plate 22 and the top side of the flexible circuit board 241, so
that the light-emitting diode 242 can be stably positioned at a
location corresponding to the lateral side 221 of the light guide
plate 22.
Referring to FIG. 7, a liquid crystal display device 120 according
to the third embodiment of this disclosure has an overall structure
similar to that of the first embodiment. However, in this
embodiment, because the support frame 1 is made by injection
molding a plastic material so that the strength thereof is weak, to
enhance the strength of the support frame 1, a metal frame 62 is
disposed in the cavity 123, and receives clampingly the
light-emitting unit 24 and the light guide plate 22. Because the
metal frame 62 can enhance the strength of the support frame 1 and
protect the light-emitting unit 24, when the support frame 1 is
deformed caused by an external force, the light-emitting unit 24
can be prevented from being displaced.
Further, to enhance flatness of the first support 111 so that the
light-emitting diode 242 cannot be slantingly disposed when
assembled to the support frame 1, the metal frame 62 is fixed to
the support frame 1 by, for example, a screw fastening method. The
metal frame 62 has a substantially U-shaped cross section, and
includes a vertical plate 621, a lower clamping plate 622 extending
horizontally from a bottom end of the vertical plate 621, and an
upper clamping plate 623 extending horizontally from a top end of
the vertical plate 621. The lower clamping plate 622 abuts against
the first support 111 and engages the bottom side of the flexible
circuit board 241. The upper clamping plate 623 engages a top end
of the light-emitting diode 242 and the top side 222 of the light
guide plate 22. Through the upper and lower clamping plates 623,
622 that cooperatively clamp therebetween the light-emitting unit
24 and the light guide plate 22, the light-emitting diode 242 can
be positioned at a location corresponding to the lateral side 221
of the light guide plate 22. Hence, light generated by the
light-emitting diode 242 can be uniformly emitted to the light
guide plate 22 through the lateral side 221 thereof.
Referring to FIGS. 8 and 9, a liquid crystal display device 130
according to the fourth embodiment of this disclosure has an
overall structure similar to that of the first embodiment. However,
in this embodiment, the liquid crystal display device 130 further
comprises a glass 7 to cover the opening 51. The glass 7 is a
tempered glass.
The upper casing 5 includes a first coupling portion 53. The glass
7 includes a second coupling portion 71 coupled to the first
coupling portion 53. Through the interconnection of the first and
second coupling portions 53, 71, the glass 7 can be fixed to the
upper casing 5 so as to cover the opening 51. In this embodiment,
the first coupling portion 53 is an inner periphery of the upper
wall 54 and defines the opening 51. The second coupling portion 71
is configured as an annular groove that extends inwardly from an
outer peripheral face 70 of the glass 7 and receiving engagingly
the inner periphery or the first coupling portion 53. The
connection between the first and second coupling portions 53, 71
can be accomplished using the below two methods.
In the first method, the glass 7 is cooled to shrink its volume,
after which the glass 7 is brought to a working environment having
a room temperature. The glass 7 is then inserted into the opening
51 of the upper casing 5 aligning the second coupling portion 71
with the first coupling portion 53. After the glass 7 is placed at
room temperature for a period of time, the glass 7 will return to a
room temperature condition and the volume thereof will expand.
Hence, the second coupling portion 71 is coupled fixedly to the
first coupling portion 53.
In the second method, the upper casing 5 is heated to expand its
volume, after which the upper casing 5 is brought to a working
environment having a room temperature. The glass 7 is then inserted
into the opening 51 of the upper casing 5 aligning the second
coupling portion 71 with the first coupling portion 53. After the
upper casing 5 is placed at room temperature for a period of time,
the upper casing 5 will return to a room temperature condition and
the volume thereof will shrink. Hence, the second coupling portion
71 is coupled fixedly to the first coupling portion 53.
In both methods, because the second coupling portion 71 can be
coupled fixedly to the first coupling portion 53, the glass 7 can
be assembled fixedly and stably to the upper casing 5. Hence, the
structural strength of the upper casing 5 can be enhanced.
Moreover, the glass 7 can be configured to partly or fully cover
the upper wall 54, so that the liquid crystal display device 130
can exhibit a frameless visual effect. It should be noted that the
connection between the first and second coupling portions 53, 71 is
not limited to the aforesaid disclosures.
Referring to FIGS. 10, 11 and 12, a liquid crystal display device
140 according to the fifth embodiment of this disclosure has an
overall structure similar to that of the first embodiment. However,
in this embodiment, the main surrounding wall 12 of the support
frame 1 includes a left wall 124, a right wall 125, a front wall
126 connected to front ends of the left and right walls 124, 125,
and a rear wall 127 connected to rear ends of the left and right
walls 124, 125. The support frame 1 further includes two elongated
extension plates 15 extending respectively and outwardly from outer
sides of the left and right walls 124, 125. The liquid crystal
display device 140 further comprises a lower casing 63, two
coupling rods 64, and two fasteners 65. The lower casing 63 covers
a bottom side of the support frame 1, and is coupled to the upper
casing 5. In this embodiment, the upper casing 5 and the lower
casing 63 are made of metal. An outer peripheral wall 631 of the
lower casing 63 and the outer peripheral wall 52 of the upper
casing 5 are coupled fixedly to each other by using a
hook-and-groove interlocking means or a screw fastening method.
However, the connection between the outer peripheral walls 631, 52
is not limited to the aforesaid disclosures.
The two coupling rods 64 are made of metal and are connected
respectively to two hinges (not shown) of the notebook computer.
The hinges are disposed in a system housing (not shown) of the
notebook computer, so that the liquid crystal display device 140
can rotate relative to the system housing through the hinges. Each
of the coupling rods 64 is elongated, and is disposed between a
base plate 632 of the lower casing 63 and a respective extension
plate 15. Each fastener 65 is configured as a screw that extends
through one of the extension plates 15 and the respective coupling
rod 64 and that engages threadedly the base plate 632, so that each
extension plate 15 and the respective coupling rod 64 are fixed to
the base plate 632. By fixing the coupling rods 64 between the base
plate 632 and the respective extension plates 15, the structural
strength among the hinges, the support frame 1 and the lower casing
63 can be enhanced. Hence, the liquid crystal display device 140
can rotate smoothly relative to the system housing through the
hinges. Further, as shown in FIG. 13, the base plate 632 of the
lower casing 63 can be provided with two internally threaded studs
633, so that the screws or fasteners 65 can be threaded
respectively to threaded holes (not shown) in the studs 633. In
this case, there is no need to form threaded holes in the base
plate 632 for threaded engagement with the fasteners 65. The
internally threaded studs 633 can be formed with deeper threaded
holes so as to enhance the fastening strength of the fasteners 65
when the fasteners 65 are engaged to the studs 633.
As shown in FIG. 14, which is a fragmentary sectional side view of
the liquid crystal display device 140, to effectively reduce the
width of the upper wall 54 of the upper casing 5 so that the liquid
crystal display device 140 has a narrow upper frame, the below
structural design is employed.
The support frame 1 is formed with an accommodation groove 112. The
liquid crystal display device 140 further comprises a control
circuit board 66 disposed in the accommodation groove 112, and a
flexible transmission circuit 67 connected electrically to the
liquid crystal display panel 3 and the control circuit board 66.
Through the presence of the accommodation groove 112 that
accommodates the control circuit board 66, the control circuit
board 66 and the flexible transmission circuit 67 can be disposed
between the upper casing 5 and the lower casing 63. Either the
upper casing 5 or the lower casing 63 does not need an additional
structure to receive the control circuit board 66. Hence, the width
of the upper wall 54 can be reduced, and the liquid crystal display
device 140 can have a narrow upper frame.
Concretely speaking, the bottom wall 11 of the support frame 1 has
a bottom face 113 that is recessed to form the accommodation groove
112, so that the control circuit board 66 can be received inside
the bottom wall 11. The flexible transmission circuit 67 is
configured as a circuit band made by a chip on film (COF)
technology and transmitting a control signal generated by the
control circuit board 66 to the liquid crystal display panel 3. The
flexible transmission circuit 67 is bent downward and then inward
extending around the support frame 1 to connect with the control
circuit board 66. Through this, the flexible transmission circuit
67 can be positioned between the support frame 1 and the
positioning element 4.
Referring to FIGS. 15 to 17, a liquid crystal display device 150
according to the sixth embodiment of this disclosure has an overall
structure similar to that of the first embodiment. However, to
effectively reduce the width of the upper wall 54 of the upper
casing 5 so that the liquid crystal display device 150 can have a
narrow upper frame, the liquid crystal display device 150 of this
embodiment can be realized through the below structural design.
In this embodiment, the rear wall 127 of the main surrounding wall
12 includes two positioning structures 128 spaced apart in a
left-right direction to position the backlight module 2 so that the
backlight module 2 is assembled to the support frame 1 in a correct
direction of assembly. Further, the positioning structures 128 can
position the backlight module 2 in the receiving space 13.
Concretely speaking, each of the positioning structures 128
includes a positioning groove 131 and a positioning stud 132
provided in the positioning groove 131. The optical film layer 23
of the backlight module 2 includes two projections 231 each having
a shape matching that of the positioning groove 131 so as to engage
with the same. Each of the projections 231 is formed with a
positioning hole 232 having a shape matching that of the
positioning stud 132. When each projection 231 engages the
respective positioning groove 131, the positioning stud 132 of each
positioning structure 128 extends into the positioning hole 232 of
the respective projection 231 simultaneously, so that the optical
film layer 23 of the backlight module 2 can be stably positioned in
the receiving space 13 and will not rocked. By providing the
positioning structures 128 on the rear wall 127 of the main
surrounding wall 12, the size of the left and right sides of each
of the support frame 1 and the upper wall 54 of the upper casing 5
can be effectively reduced. For example, as shown in FIG. 16, a gap
between the right wall 125 and the auxiliary surrounding wall 14
can be omitted, so that the liquid crystal display device 150 can
have a narrow frame.
Referring to FIGS. 18 to 20, a liquid crystal display device 160
according to the seventh embodiment of this disclosure has an
overall structure similar to that of the first embodiment. However,
to effectively reduce the width of the upper wall 54 of the upper
casing 5 so that the liquid crystal display device 160 can have a
narrow upper frame, the liquid crystal display device 160 of this
embodiment can be realized through the below structural design.
In this embodiment, the liquid crystal display device 160 further
comprises a double-sided adhesive tape 68 adhering the liquid
crystal display panel 3 to one side of the second support 121. The
main surrounding wall 12 further includes a retention portion 129
projecting from the other side of the second support 121. The
double-sided adhesive tape 68 and the retention portion 129 are
opposite to each other. When the liquid crystal display panel 3 is
assembled on the support frame 1, the liquid crystal display panel
3 is placed on the second support 121 such that the double-sided
adhesive tape 68 adheres one side of the liquid crystal display
panel 3 and the retention portion 129 retains the other side of the
liquid crystal display panel 3 in a retention hole 10 (see FIG. 18)
defined by the retention portion 129 and the second support 121.
Hence, the liquid crystal display panel 3 can be fixed stably on
the second support 121 of the support frame 1. Through the
aforesaid configuration, the positioning element 4 shown in FIG. 2
can be dispensed herewith, and the support frame 1 can omit a space
for receiving the positioning element 4. Hence, the width of each
of the support frame 1 and the upper wall 54 of the upper casing 5
can be effectively reduced, so that the liquid crystal display
device 160 can have a narrow frame.
With reference to FIGS. 19 to 21, further, in considering rework
for the liquid crystal display device 160, in this embodiment, the
double-sided adhesive tape 68 includes a pull portion 681, and two
double-sided adhesive tape portions 682 adhered respectively to two
opposite sides of the pull portion 681. The pull portion 681 is
made of PET material. The double-sided adhesive tape portions 682
are further adhered to the second support 112 at one side of the
main surrounding wall 12 and the liquid crystal display panel 3,
respectively. One end of the pull portion 681 is exposed from one
side of the liquid crystal display panel 3, as best shown in FIG.
19. When it is desired to disassemble the liquid crystal display
device 160 for a rework operation, the upper casing 5 is first
removed from the support frame 1. Afterwards, the exposed end of
the pull portion 681 is pulled out in the direction of an arrow
shown in FIG. 19 so as to separate the double-sided adhesive tape
portions 682 from the second support 112 and the liquid crystal
display panel 3, respectively. Subsequently, the liquid crystal
display panel 3 can be disengaged from the retention portion 129.
Because disassembly is very simple and convenient, the time of
disassembly can be shortened.
Alternatively, as shown in FIG. 22, the width of the double-sided
adhesive tape 68 can be enlarged so that the double-sided adhesive
tape 68 can be adhered to an outer wall face of the main
surrounding wall 12, the bottom wall 11, and a signal transmission
wire 69, simultaneously.
Referring to FIG. 23, a liquid crystal display device 170 according
to the eighth embodiment of this disclosure has an overall
structure similar to that of the seventh embodiment. However, in
this embodiment, the liquid crystal display device 170 comprises
two double-sided adhesive tapes 68 to adhere the liquid crystal
display panel 3 to two opposite sides of the second support 121.
Hence, the liquid crystal display panel 3 can be stably adhered to
the second support 121 of the support frame 1.
Referring to FIG. 24, a liquid crystal display device 180 according
to the ninth embodiment of this disclosure has an overall structure
similar to that of the seventh embodiment. However, in this
embodiment, the main surrounding wall 12 further includes two
retention portions 129 projecting respectively from two opposite
sides of the second support 121 to retain two opposite sides of the
liquid crystal display panel 3 in the retention holes 10.
Similarly, the liquid crystal display panel 3 can be positioned
stably on the second support 121 of the support frame 1.
Referring to FIG. 25, a liquid crystal display device 190 according
to the tenth embodiment of this disclosure has an overall structure
similar to that of the first embodiment. However, in this
embodiment, the main surrounding wall 12 of the support frame 1
further includes a third support 133 spacedly above the second
support 112 and having a horizontal support face. The liquid
crystal display device 190 further includes a touch control panel 8
supported on the third support 133. In this embodiment, the touch
control panel 8 is a capacitive touch control panel that is adhered
fixedly to the third support 133 by using glue or double-sided
adhesive tape so as to be positioned stably above the liquid
crystal display panel 3. Because the liquid crystal display panel 3
and the touch control panel 8 are respectively positioned on the
second and third supports 121, 133 of the support frame 1, accuracy
of assembly between the liquid crystal display panel 3 and the
touch control panel 8 can be enhanced, and the accumulated
tolerance of the components can be reduced.
Referring to FIG. 26, the liquid crystal display device 190 is
applied in an electronic equipment 200, such as a tablet computer.
In this case, a lower casing 63 having a mounting space 634 is
provided. The electronic equipment has an electronic device 9
disposed in the mounting space 634. The electronic device 9
includes a motherboard, a hard disk, a battery, and other essential
electronic components for providing normal operation of the
electronic equipment 200. The liquid crystal display device 190 is
disposed in the mounting space 634 such that the bottom wall 11 of
the support frame 1 is located above the electronic device 9. An
outer peripheral wall 631 of the lower casing 63 surrounds an outer
periphery of the main surrounding wall 12 of the support frame 1,
and abuts against the support frame 1. The outer peripheral wall
631 and the main surrounding wall 12 may be interconnected to each
other such as by using a hook-and-groove interlocking means or a
screw fastening means. The center of the bottom wall 11 is formed
with a through hole 114 in spatial communication with the receiving
space 13. The electronic device 9 can transmit power and signals to
the backlight module 2, the liquid crystal display panel 3 and the
touch control panel 8 of the liquid crystal display device 190 by
using a cable (not shown) that extends through the through hole
114. By embodying the liquid crystal display device 190 of this
disclosure, the number of components of the electronic equipment
200 can be reduced, so that the assembly time and the manufacturing
costs thereof can be saved. It should be noted that the connection
between the outer peripheral wall 631 and the main surrounding wall
12 is not limited to the aforesaid disclosures.
In summary, the liquid crystal display device 100-190 of each of
the embodiments uses the first and second supports 111, 121 of the
integrally formed support frame 1 to support the backlight module 2
and the liquid crystal display panel 3, respectively, so that the
number of components of the liquid crystal display device 100-190
can be reduced and the structure of the liquid crystal display
device 100-190 simple. Further, the assembly time can be shortened,
the manufacturing costs can be saved, and the accumulated tolerance
of the components can be reduced. Hence, the objects of this
disclosure can be realized.
While the present disclosure has been described in connection with
what are considered the most practical embodiments, it is
understood that this disclosure is not limited to the disclosed
embodiments but is intended to cover various arrangements included
within the spirit and scope of the broadest interpretation so as to
encompass all such modifications and equivalent arrangements.
