DETAILED DESCRIPTION OF DISCLOSED EMBODIMENTS
[0032] FIG. 1 is a schematic view of a display device according to
an embodiment. FIG. 2 is a partially enlarged diagram of an area A
in FIG. 1. FIG. 3 is a schematic cross-sectional view taken along a
line I-I' in FIG. 1. To make the figures clear, a certain
components are omitted in the schematic view of FIG. 1 and the
enlarged diagram of FIG. 2. Referring to FIGS. 1 to 3, a display
device 100 includes a backlight module 120, a display module 140, a
driver board 160 and a front frame 180. In the present embodiment,
the display module 140 is, for example, a liquid crystal display
module. The backlight module 120 is, for example, a side-light
backlight module for providing a light source required by the
display module 140 for display. The backlight module 120 includes a
light guide 122, a bottom frame 124 and a first light bar 126.
[0033] The light guide 122 has a light incident surface 122a and a
light-emitting surface 122b adjacent to each other. The bottom
frame 124 has a clip portion 1242, a first tongue piece 1244 and a
first hole 124a. A driver board 160 is locked to the first tongue
piece 1244, and the first tongue piece 1244 is folded from the
bottom frame 124 to form the first hole 124a. The first tongue
piece 1244 is connected to the clip portion 1242. The first tongue
piece 1244 extends away from the clip portion 1242, such as a
direction away from the light guide 122 in FIG. 3. The front frame
180 is assembled with the bottom frame 124 and covers the periphery
of the display module 140.
[0034] The first light bar 126 has a flexible circuit board 1262, a
light source 1264 and a first connector 1266. The flexible circuit
board 1262 has a main body 1262a and an extending portion 1262b
connected to each other. The light source 1264 is disposed on the
main body 1262a, and the first connector 1266 is disposed on the
extending portion 1262b. In the present embodiment, the light
source 1264 is, for example, a light-emitting diode, and after the
emitted light enters the light guide 122 from the light incident
surface 122a, the light departs from the light guide 122 from the
light-emitting surface 122b and enters the display module 140. The
display module 140 is disposed above the backlight module 120, and
the driver board 160 is electrically connected to the display
module 140 and disposed on the first tongue piece 1244. The
backlight module 120 is between the driver board 160 and the
display module 140. The driver board 160 drives the display module
140 to generate display images. The main body 1262a of the flexible
circuit board 1262 is disposed inside the clip portion 1242, and
the extending portion 1262b is disposed on the first tongue piece
1244.
[0035] In the present embodiment, the first tongue piece 1244 is
folded from the bottom frame 124 to form the first hole 124a,
wherein the driver board 140 is screwed to the first tongue piece
1244, and the first hole 124a serves as a cable hole for the
flexible circuit board 1262, so that the first connector 1266 at
the end of the flexible circuit board 1262 passes through the first
hole 124a to connect to other external circuits. Adopting the first
hole 124a formed as the cable hole when folding the bottom frame
124 to manufacture the first tongue piece 1244, the bottom frame
124 does not require an additional hole as the cable hole. Thereby,
the number of holes on the bottom frame 124 is effectively reduced
so that the backlight module 120 has favorable structural
strength.
[0036] The frame 124 of the present embodiment is formed
integrally. For instance, the bottom frame 124 is cut when forming
the first tongue piece 1244, and the cut portion is folded to make
the first tongue piece 1244 and forms the first hole 124a after
being folded. Thereby, the first hole 124a matches the outer
contour of the first tongue piece 1244. In addition, in the present
embodiment, the light guide 122 further has a bottom surface 122c,
and the bottom surface 122c is opposite to the light-emitting
surface 122b. The first light incident surface 122a is adjacent to
a light-emitting surface 122b and the bottom surface 122c. In the
present embodiment, the first hole 124a is at the light-emitting
surface 122b. In other words, the first tongue piece 1244 is folded
from the light-emitting surface 122b toward a direction away from
the clip portion 1242, such as a direction away from the light
guide 122 in FIG. 3.
[0037] In the present embodiment, the first connector 126 has a
first width W1, and the first hole 124a has a first diagonal width
D1, wherein the first diagonal width D1 is larger than or equal to
the first width W1. Thereby, it could be avoided that the first
diagonal width D1 is too small to allow the first connector 124a to
successfully pass through the first hole 124a. In addition, in the
present embodiment, the extending portion 1262b on the first tongue
piece 1244 is overlapped with the driving circuit 160 on the first
tongue piece 1244 in an orthogonal projection, and the extending
portion 1262b is between the first tongue piece 1244 and the
driving circuit 160. Part of the extending portion 1262b is
accommodated in the first hole 124a, so that the first connector
1266 is disposed outside the bottom frame 124.
[0038] In the present embodiment, the first tongue piece 1244 has a
screw hole 1244a, and the driver board 160 is locked on the first
tongue piece 1244 via the screw hole 1244a with a lock accessory
(not shown, such as a screw). In the present embodiment, circuits
of the first connector 1266 on the first tongue piece 1244 are not
overlapped with the screw hole 1244a in an orthogonal projection.
Thereby, the lock accessory is prevented from passing through the
circuit and destructing the circuit when passing through the screw
hole 1244a. More specifically, the first connector 1266 includes a
through hole 1266a disposed correspondingly to the screw hole
1244a, and the lock accessory passes through the through hole 1266a
and the screw hole 1244a to lock the driver board 160 on the first
tongue piece 1244. The circuit on the first connector 1266, for
example, surrounds the through hole 1266a and avoids the through
hole 1266a, so that the circuit on the first connector 1266 is able
to avoid the position of the screw hole 1244a.
[0039] It should be noted that the reference numerals and a part of
the contents in the previous embodiment are used in the following
embodiments, in which identical reference numerals indicate
identical or similar components, and repeated description of the
same technical contents is omitted. For a detailed description of
the omitted parts, reference can be found in the previous
embodiment, and no description will be repeated in the following
embodiments.
[0040] FIG. 4 is a schematic cross-sectional view of a display
device according to another embodiment. The embodiment of FIG. 4 is
similar to that of FIG. 1, and the embodiments differ primarily in
the structure of the bottom frame. Referring to FIG. 4, in the
present embodiment, a bottom frame 224 of a display device 200 has
a clip portion 2242, a first tongue piece 2244 and a first hole
224a. In addition, a light guide 122 of the display device 200 has
a first light incident surface 122a, a light-emitting surface 122b
and a bottom surface 122c opposite to each other, wherein the first
light incident surface 122a is adjacent to the light-emitting
surface 122b and the bottom surface 122c, and the first hole 224a
is at the bottom surface 122c. In other words, the first tongue
piece 2244 is folded from the bottom surface 122c toward a
direction away from the clip portion 2242, such as a direction away
from the light guide 122 in FIG. 4. It is worth mentioning that in
such an arrangement, the first tongue piece 2244 is between the
extending portion 1262b and the driving circuit 160. In the present
embodiment, adopting the first hole 224a formed to be as the cable
hole when folding the bottom frame 224 to make up the first tongue
piece 2244, the bottom frame 224 does not require an additional
hole as the cable hole. Thereby, the number of holes on the bottom
frame 224 is effectively reduced so that the backlight module 220
has favorable structural strength.
[0041] FIG. 5 is a schematic cross-sectional view of a display
device according to another embodiment. The embodiment of FIG. 5 is
similar to that of FIG. 4, and the embodiments differ primarily in
the position of the flexible circuit board. In the present
embodiment, a flexible circuit board 2262 of a display device 200a
has a main body 2262a and an extending portion 2262b connected to
each other, wherein a light source 1264 is disposed on the main
body 2262a. As illustrated in FIG. 5, the main body 2262a shields
the first hole 224a, so as to prevent light emitted from the light
source 1264 from leaking out of the first hole 224a to have the
effect of reducing light leakage.
[0042] According to the position and number of light bars and the
number of connectors, the backlight module of the display module
may take a plurality of forms, which are described with exemplary
embodiments below.
[0043] FIG. 6 is a schematic top view of a backlight module
according to another embodiment. Referring to FIG. 6, a backlight
module 320 includes a light guide 322, a bottom frame 324 and a
first light bar 326. The bottom frame 324 has a first hole 324a and
a first tongue piece 3244, wherein the first tongue piece 3244 is
folded from the first hole 324a, and the driver board (not shown)
is screwed on the first tongue piece 3244. In addition, the bottom
frame 324 has a first side surface A1 and a second side surface A2
connected to each other, and the present embodiment is described
with the example that the first side surface A1 is perpendicular to
the second side surface A2. The first light bar 326 has a flexible
circuit board 3262 and a first connector 3266. The flexible circuit
board 3262 has a main body 3262a and an extending portion 3262b
connected to each other, and the first connector 3266 is disposed
on the extending portion 3262b. In the present embodiment, a light
source (not shown) is situated on the first side surface A1 and is
disposed on the main body 3262a, and the first hole 324a is at the
second surface A2.
[0044] As illustrated in FIG. 6, the main body 3262a of the
flexible circuit board 3262 extends from the first side surface A1
of the bottom frame 324 to the second side surface A2 and appears
in a L-like shape. In addition, a connecting portion 3262b
penetrates through the first hole 324a of the second side surface
A2 so that the first connector 3266 is outside the bottom frame
324. In the present embodiment, the light source and the first hole
324a are at different side surfaces of the bottom frame 324 (such
as the first side surface A1 and the second side surface A2 in FIG.
6). The flexible circuit board 3262 extends along these side
surfaces and have different shapes (such as the L-shape in FIG. 6),
so that design of the the backlight module 320 is more flexible. In
the present embodiment, by disposing the first light bar 326 on a
short side (the first side surface A1), the number of light sources
is reduced, and meanwhile mura formed by spacings between the light
sources is avoided.
[0045] It is worth mentioning that the first tongue piece 3244 of
the present embodiment has a screw hole 3244a, and as illustrated
in FIG. 6, the connecting portion 3262b keeps away from the screw
hole 3244a, and the first connector 3266 on the first tongue piece
1244 is not overlapped with the screw hole 3244a in an orthogonal
projection. Thereby, when the driver board is locked on the first
tongue piece 3244 with a lock accessory such as a screw, the
flexible circuit board 3262 is not affected.
[0046] FIG. 7 is a schematic top view of a backlight module
according to another embodiment. Referring to FIG. 7, a backlight
module 420 includes a light guide 422, a bottom frame 424 and a

piece 5244 is folded from the first hole 524a, and the second
tongue piece 5246 is folded from the second hole 524b. The bottom
frame 524 has a first side surface B1 and a second side surface B2
opposite to each other, wherein the first hole 524a is at the first
side surface B1 and the second hole 524b is at the second side
surface B2.
[0048] The light guide 522 has a first light incident surface 522a
and a second light incident surface 522b at two opposite sides of
the light guide 522, wherein the first light bar 526 is between the
first side surface B1 and the first light incident surface 522a,
and the second light bar 528 is between the second side surface B2
and the second light incident surface 522b. The backlight module
520 of the present embodiment includes a plurality of light bars
526 and 528, and the light bars 526 and 528 are at two opposite
side surfaces B1 and B2 of the bottom frame 524. The tongue pieces
are folded from bottom frame to form holes 524a and 524b in
different side surface (B1-B2) chosen among the position of the
light bar 526-528, so that the design of the backlight module 520
is more flexible. In the present embodiment, brightness is enhanced
by the plurality of light bars 526 and 528.
[0049] In light of the above, the backlight module adopts the first
hole formed as the cable hole when folding the bottom frame to form
the first tongue piece, so that the bottom frame does not require
an additional hole as the cable hole. Thereby, the number of holes
on the bottom frame is effectively reduced so that the backlight
module has favorable structural strength. In addition, adopting the
backlight module having favorable structural strength in the
display device further enhances the reliability of the display
device.
[0050] On the other hand, there are different designs for the
position and number of the light bars or the number of connectors
in the backlight module, so that the backlight module and the
display device having the backlight module have good flexibility in
design.
[0051] Although the disclosure has been described with reference to
the above embodiments, it will be apparent to one of ordinary skill
in the art that modifications to the described embodiments may be
made without departing from the spirit and scope of the disclosure.
Accordingly, the scope of the disclosure will be defined by the
attached claims and not by the above detailed descriptions.
