Description
RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional
Application Ser. No. 61/359,811, filed on Jun. 29, 2010, which is
herein incorporated by reference.
BACKGROUND
[0002] 1. Field of Invention
[0003] The present invention relates to a display device.
[0004] 2. Description of Related Art
[0005] In recent years, owing to the rapid development of the
electronics industry and the information industry, the related
products are also increasingly sophisticated. For the current
personal computers, in addition to seek more rapid and more
powerful computing units and a wide range of peripheral equipments
to meet user needs, the compact sized portable computers are also
the key area of development of the industries.
[0006] For example, liquid crystal displays have advantages such as
high definition, small size, light weight, low driving voltage, low
power consumption, and wide range of applications, so they can be
widely applied in portable televisions, mobile phones, camcorders,
notebook computers, desktop monitors, and other consumer
electronics products and become the mainstream of the displays.
[0007] A display device applied in a notebook computer mainly
includes a cover and a display module. The display module includes
a first side and a second side, wherein the first side includes a
display region and the second side is adjacent to or mounted to the
cover. With different designs of products, the cover not only can
be made of plastic and formed to be thin shell by injection molding
but also can be made of metal (such as aluminum) and formed to be
thin shell by stamping. The display module thus can be mounted with
the cover to form the display device. Besides, in order to mount
the display device to the base, the display device can include a
hinge.
[0008] Generally, the hinge is pivotally connected to the hinge
module on the cover. The hinge module is commonly mounted to the
cover by fastening with screws. The hinge module not only can be
used to be pivotally connected to the hinge but also can be used to
mount and support the display module. In other words, the display
module and the cover can be mounted to each other by fastening the
hinge module to the sidewall of the display module.
[0009] However, because the hinge module is fastened to the cover
by screws, the thickness of the whole display device cannot be

[0045] Reference will now be made in detail to the present
embodiments of the invention, examples of which are illustrated in
the accompanying drawings. Wherever possible, the same reference
numbers are used in the drawings and the description to refer to
the same or like parts.
[0046] FIG. 1 is a front view showing a display device according to
an embodiment of the invention. FIG. 2 is a back view showing the
display device. in FIG. 1. FIG. 3 is an exploded view showing the
display device in FIG. 1. The structures of the invention can be
applied to a display device that has backlight or a display device
that does not have backlight (i.e., the display device that
actively emits light). The display device that has backlight can be
a LCD (Liquid Crystal Display) device. The display device that does
not have backlight can be an OLED (Organic Light-Emitting Diode)
device. Although the following embodiment of the structures of the
invention is applied to a display device that has backlight, but
the scopes of the invention will not be limited thereby. Please
refer to FIG. 1 to FIG. 3, the display device 100 of the first
embodiment includes a cover 110, a frame 120, and a panel module,
wherein the panel module includes a glass module 130 and a
backlight module 140. The frame 120 can be mounted to the cover
110, and the panel module can be fixed to the frame 120 along a
direction to form a display module. The direction is the normal
vector of the display region 132 on the display module. When the
display device 100 is a display device that has backlight, the
display module is a display module that has backlight. The display
device 100 in the embodiment can be applied in a notebook computer,
and the display device 100 can be pivotally connected to a host
(not shown) of the notebook computer with the hinge 110a
illustrated in FIG. 3. In other embodiments, the display device 100
can be applied to electronic devices such as a tablet computer, a
mobile phone, a television, and etc.
[0047] Please refer to FIG. 4. FIG. 4 is a partial and sectional
view showing the display device in FIG. 1. The cover 110 of the
embodiment has a base plate 112 and a sidewall 114. A supporting
member of the frame 120 is protruded inward, and the supporting
member includes a first supporting portion 122 and a second
supporting portion 124. The first end 122a of the first supporting
portion 122 is engaged to the sidewall 114 of the cover 110. The
second supporting portion 124 is connected to the second end 122b
of the first supporting portion 122 and leans or does not lean the
base plate 112 of the cover 110 depending on the needs of product
design. The glass module 130 is fixed to the first supporting
portion 122 along a direction, and the backlight module 140 is
disposed between the glass module 130 and the base plate 112 and
fixed to the second supporting portion 124 along the same
direction, wherein the direction along that the glass module 130
and the backlight module 140 are fixed to the frame 120 is the
normal vector of the display region 132 on the display module. With
the needs of product design, the first supporting portion 122 is
located on the frame 120 at a position outside that of the second
supporting portion 124, so the light can be totally transmitted to
the glass module 130 from the backlight module 140. An opening can
be formed at the center of the frame 120, and the light generated
by the backlight module 140 can be transmitted to the glass module
130 via the opening so as to increase the brightness of the display
region 132. When the panel module is fixed to the frame 120, the
frame 120 can surround the periphery of the panel module, and the
panel module must cover the opening to increase the brightness of
the display region 132. With the needs of product design, the frame
120 can further include a retaining portion 126 for preventing the
glass module 130 from leaving the first supporting portion 122 and
for protecting the glass module 130. If the frame 120 does not
include the retaining portion 126, the invention can further
include a decorative frame 190 illustrated in FIG. 3. The
decorative frame 190 is located at the periphery of the glass
module 130 and engaged to the frame 120 or the cover 110 to protect
the glass plates of the glass module 130 from breakage while being
impacted. The glass module 130 includes a first side and a second
side. The first side of the glass module 130 includes the display
region 132 and is used to contact the retaining portion 126 or the
decorative frame 190. The second side of the glass module 130
contacts or is fixed to the backlight module 140. The panel module
also includes a first side and a second side, wherein the first
side of the panel module is the first side of the glass module 130
and includes the display region 132. The second side of the panel
module is fixed to the frame 120, so as to combine the panel module
and the frame 120 to form the display module. The first side and
the second side of the panel module are two planes in parallel with
each other.
[0048] Under the configurations that the frame 120 has the
retaining portion 126, the glass module 130 and the backlight
module 140 of the panel module are both fixed to the frame 120, the
frame 120 is engaged to the cover 110, and the glass module 130 is
retained by the retaining portion 126, the assembly of the display
module can be accomplished. Because the display module is mounted
to the cover 110 without screws, the cover 110 does not need to
provide space to be fastened by screws so as to have a thinner
thickness and the display module does not need to be formed screw
holes so as to have a larger display region 132 (as shown in FIG. 1
and FIG. 3). When the glass module 130 and the backlight module 140
of the panel module are just fixed to the frame 120 to form the
display module, the frame 120 is the only structure that provides
support. Thereby, the display module and the cover 110 can be
combined to each other to form the display device 100 with the
assistance of the support of the frame 120.
[0049] In the embodiment, the first supporting portion 122 and the
second supporting portion 124 can be made of plastics that have
buffering effect, so as to provide support to the glass module 130
and the backlight module 140. The retaining portion 126 can be made
of rubber and integrally formed with the first supporting portion
122 and the second supporting portion 124 by co-injection molding.
The cover 110 of the embodiment can be made of metals such as
aluminum or other proper metals. But the invention will not be
limited thereby. In other embodiments, the cover 110 can also be
made of plastics and have integrally formed reinforcing ribs or
metal members for improving structural strength.
[0050] As shown in FIG. 4, the first supporting portion 122 of the
embodiment has a first supporting surface 122c, and the second
supporting portion 124 has a second supporting surface 124a. The
distance between the first supporting surface 122c and the base
plate 112 is longer than that between the second supporting surface
124a and the base plate 112. The orthogonal projection of the
peripheral part 134 of the glass module 130 on the base plate 112
and that of the backlight module 140 on the base plate 112 do not
overlapped to each other. Therefore, the glass module 130 and the
backlight module 140 that are stacked to each other are
respectively fixed to the first supporting surface 122c and the
second supporting surface 124a, wherein the glass module 130 is
fixed to the first supporting surface 122c with the peripheral part
134, and the glue applied between the panel module and the frame
120 includes epoxy.
[0051] Besides, the sidewall 114 of the cover 110 has a first
fixing portion 114a, the first supporting portion 122 on the frame
120 has a second fixing portion 122d, and the cover 110 can be
mounted to the frame 120 by making the first fixing portion 114a
and the second fixing portion 122d to be engaged to each other.
After the cover 110 is mounted to the frame 120 to form the display
device 100, the position of the cover 110 is adjacent to the second
side of the panel module, and the cover 110 and the frame 120 both
provide support to the panel module so as to improve the structural
strength of the display module. After the cover 110 is mounted to
the frame 120, the sidewall 114 of the cover 110 will cover the
sidewall of the frame 120 to avoid light leakage of the display
device.
[0052] As shown in FIG. 4, when the display device 100 that has
backlight is a liquid crystal display device, the glass module 130
of the first embodiment includes a first glass plate 136, a liquid
crystal layer 137, and a second glass plate 138. The first glass
plate 136 is located at the second side of the panel module and
fixed to the first supporting portion 122, and the liquid crystal
layer 137 is disposed between the first glass plate 136 and the
second glass plate 138. The second glass plate 138 is located at
the first side of the panel module for contacting the retaining
portion 126 or the decorative frame 190. The first glass plate 136
and the second glass plate 138 can be made of transparent materials
with high strength, so as to protect the liquid crystal layer 137
and make the light emitted by the backlight module 140 suitable to
be transmitted to the liquid crystal layer 137 through the first
glass plate 136. Finally, after the liquid crystal layer 137
processes the light, users can watch the images displayed by the
display module through the second glass plate 138.
[0053] As shown in FIG. 5 which is a stereoscopic view showing the
cover of the invention. The cover 110 of the invention can further
include a hinge module 106. The hinge module 106 mainly includes a
bracket 106a and a pivotal portion 106b. The bracket 106a of the
hinge module 106 can be fixed to the inner surface of the cover 110
by glue 2, wherein the inner side of the cover 110 is adjacent to
the second side of the display module and the glue 2 includes
epoxy. The pivotal portion 106b of the hinge module 106 can be
connected to the bracket 106a. The hinge 108 can be pivotally
connected to the pivotal portion 106b. Therefore, the hinge 108 can
be mounted to the cover 110 by the hinge module 106 that is fixed
to the cover 110. With different designs of products, the pivotal
portion 106b and the bracket 106a of the hinge module 106 can be
mounted to each other by a fixed method, which is a thermal binding
method, a screw fastening method, or a riveting method, so as to
make the pivotal portion 106b able to pivotally connect the hinge
108. In order to provide enough mounting strength to the hinge 108
when the hinge 108 is forced in operation, the pivotal portion 106b
and the hinge 108 are generally connected to each other by the
screw fastening method. Generally, the bracket 106a is adjacent to
but does not contact the second side of the panel module, so as to
prevent the display device from the defeat of white spots after
being assembled.
[0054] It can be seen that because the hinge module 106 is mounted
to the cover 110 by gluing the bracket 106a to the cover 110, the
thickness of the hinge module 106 in the display device 100 (i.e.,
the space between the cover 110 and the display module) is equal to
the thickness of the bracket 106a. The length of screws that are
applied to mount the hinge module 106 to cover 110 in prior arts is
about 4 mm, so the thickness of the display devices in the prior
arts cannot be reduced effectively. Relatively, the bracket 106a of
the hinge module 106 of the embodiment is plate-shaped, and a range
of the thickness of the bracket 106a is only 0.8 mm-1.0 mm.
Therefore, the bracket 106a that is fixed to the cover 110 will not
influence the whole strength of the display device 100 and can
easily reduce the thickness of the display device 100.
[0055] As shown in FIG. 5, the cover 110 of the display device 100
of the embodiment can further include four rims 100a, and the rims
100a can be classified to be two pairs and surround the cover 110.
Generally, the two pairs of the rims 100a can be classified into
long rims and short rims, and each pair of the rims 100a are
parallel to each other. The bracket 106a of the hinge module 106
can be substantially parallel to the rims 100a, and the rims 100a
are generally, but not limited to, the short rims and can be
elastically changed according to the requirements of designing or
limitations of manufacturing. Because the hinge module 106 of the
embodiment is not mounted to the cover 110 by the screw fastening
method, the length of the bracket 106a of the hinge module 106 can
be longer than half the length of one of the rims 100a so as to
increase the mounting stability between the hinge module 106 and
the cover 110. In other words, if the length of the bracket 106a of
the hinge module 106 becomes longer, the gluing area and range
between the bracket 106a and the cover 110 relatively increase, and
thus the mounting stability between the bracket 106a and the cover
110 can be increased. When the cover 110 is forced, the force can
be transmitted to the hinge 108 via the bracket 106a and the
pivotal portion 106b, so that the hinge 108 can rotate together
with the cover 110 relative to an object. So, the width of the
portion of the bracket 106a that is adjacent to the hinge 108 is
very important. Because the portion of the bracket 106a is the
interface via which the force is transmitted from the cover 110 to
the hinge 108, the portion of the bracket 106a bears larger force
than other portions. If the width of the portion of the bracket
106a is longer, the mounting capability of the bracket 106a is also
larger, so as to prevent the defeat that the hinge module 106
separates from the cover 110 during the operation of the hinge 108.
Generally, the width of the bracket 106a is directly proportional
to a desired torque of the hinge 108 and the width of the bracket
is approximately longer than 25 mm, wherein the width of the
bracket 106a is the width of the end of the bracket that is
adjacent to the hinge 108. The desired torque of the hinge 108 is
the minimum force that the hinge 108 is necessarily loaded during
operation.
[0056] The cover 110 of the embodiment further includes a
reinforcing plate 110a. The reinforcing plate 110a of the cover 110
can be fixed to the inner side of the cover 110, just like the
hinge module 106 does. The reinforcing plate 110a can be
substantially perpendicular to the bracket 106a, but the
configuration between the reinforcing plate 110a and the bracket
106a is not limited to this and can be elastically changed
according to the requirements of designing or limitations of
manufacturing. In order to increase the whole stiffness of the
display device 100, the reinforcing plate 110a of the display
device 100 and the bracket 106a of the hinge module 106 can also be
connected to each other. In other words, the reinforcing plate 110a
and the bracket 106a can be integrally formed according to the
requirements of product design and then fixed to the inner side of
the cover 110 to reinforce the strength of the cover 110. In order
to take the weight of the display device 100 into consideration,
the reinforcing plate 110a that is fixed to the cover 110 can be,
but not limited to, made from an aluminum plate of which the
thickness is 0.6 mm.
[0057] When the electronic device has a host housing, the display
device 100 of the invention can be connected to the host housing by
the hinge 108, so as to make the display device 100 to rotate
relative to the host housing. When the display device 100 covers on
the host housing, the reinforcing plate 100a on the cover 110 of
the display device 100 will correspond to the palm raise of the
host housing, so as to increase the supporting strength between the
display device 100 and the host housing and prevent the display
device 100 or the host housing from being damaged because users
press improper locations.
[0058] In another embodiment of the invention, the structures of
the invention are applied to a display device that does not have
backlight. The biggest difference between the embodiment and the
former embodiment is that the display device of the embodiment can
achieve the effect of evenly emitting light without the backlight
module. If the display device that does not have backlight is an
OLED (Organic Light-Emitting Diode) display device, the organic
light-emitting layer is generally packaged in the glass module 130
in FIG. 4 to substitute for the liquid crystal layer 137.
Therefore, the panel module only includes the glass module 130, and
the supporting member on the frame 120 can support the panel module
just by one supporting portion. When the panel module is fixed to
the supporting portion of the frame 120, the frame 120 will be the
only one structure that supports the panel module.
[0059] According to the foregoing recitations of the embodiments of
the invention, it can be seen that the invention make a panel
module and a frame to be fixed to each other to form a display
module, so the frame is the only structure that supports the frame.
Finally, a cover is mounted to the frame to form a display device.
The cover includes a hinge module, and the hinge module can be
fixed to the cover and connects a hinge, so that the hinge can
connect the display device and a host housing to each other.
Because the hinge module is fixed to the cover, the thickness of
the display device can be greatly reduced, and the mounting
strength of the display device against the rotation of the hinge
can be maintained. The display module is also mounted to the cover
without screws, so the cover does not need to provide space to be
fastened by screws so as to have a thinner thickness and the
display module does not need to be formed screw holes so as to have
a larger display region.
[0060] It will be apparent to those skilled in the art that various
modifications and variations can be made to the structure of the
present invention without departing from the scope or spirit of the
invention. In view of the foregoing, it is intended that the
present invention cover modifications and variations of this
invention provided they fall within the scope of the following
claims.
