- the bracket 106 a 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.
- 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 106 a.
- 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.
- the bracket 106 a of the hinge module 106 of the embodiment is plate-shaped, and a range of the thickness of the bracket 106 a is only 0.8 mm-1.0 mm. Therefore, the bracket 106 a 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 .
- the cover 110 of the display device 100 of the embodiment can further include four rims 100 a, and the rims 100 a can be classified to be two pairs and surround the cover 110 .
- the two pairs of the rims 100 a can be classified into long rims and short rims, and each pair of the rims 100 a are parallel to each other.
- the bracket 106 a of the hinge module 106 can be substantially parallel to the rims 100 a, and the rims 100 a are generally, but not limited to, the short rims and can be elastically changed according to the requirements of designing or limitations of manufacturing.
- the length of the bracket 106 a of the hinge module 106 can be longer than half the length of one of the rims 100 a so as to increase the mounting stability between the hinge module 106 and the cover 110 .
- the length of the bracket 106 a of the hinge module 106 becomes longer, the gluing area and range between the bracket 106 a and the cover 110 relatively increase, and thus the mounting stability between the bracket 106 a and the cover 110 can be increased.
- the cover 110 is forced, the force can be transmitted to the hinge 108 via the bracket 106 a and the pivotal portion 106 b, so that the hinge 108 can rotate together with the cover 110 relative to an object.
- the width of the portion of the bracket 106 a that is adjacent to the hinge 108 is very important. Because the portion of the bracket 106 a is the interface via which the force is transmitted from the cover 110 to the hinge 108 , the portion of the bracket 106 a bears larger force than other portions. If the width of the portion of the bracket 106 a is longer, the mounting capability of the bracket 106 a 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 .
- the width of the bracket 106 a 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 106 a is the width of the end of the bracket that is adjacent to the hinge 108 .

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. inFIG. 1 .FIG. 3 is an exploded view showing the display device inFIG. 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 toFIG. 1 toFIG. 3 , thedisplay device 100 of the first embodiment includes acover 110, aframe 120, and a panel module, wherein the panel module includes aglass module 130 and abacklight module 140. Theframe 120 can be mounted to thecover 110, and the panel module can be fixed to theframe 120 along a direction to form a display module. The direction is the normal vector of thedisplay region 132 on the display module. When thedisplay device 100 is a display device that has backlight, the display module is a display module that has backlight. Thedisplay device 100 in the embodiment can be applied in a notebook computer, and thedisplay device 100 can be pivotally connected to a host (not shown) of the notebook computer with thehinge 110 a illustrated inFIG. 3 . In other embodiments, thedisplay device 100 can be applied to electronic devices such as a tablet computer, a mobile phone, a television, and etc. - Please refer to
FIG. 4 .FIG. 4 is a partial and sectional view showing the display device inFIG. 1 . Thecover 110 of the embodiment has abase plate 112 and asidewall 114. A supporting member of theframe 120 is protruded inward, and the supporting member includes a first supportingportion 122 and a second supportingportion 124. Thefirst end 122 a of the first supportingportion 122 is engaged to thesidewall 114 of thecover 110. The second supportingportion 124 is connected to thesecond end 122 b of the first supportingportion 122 and leans or does not lean thebase plate 112 of thecover 110 depending on the needs of product design. Theglass module 130 is fixed to the first supportingportion 122 along a direction, and thebacklight module 140 is disposed between theglass module 130 and thebase plate 112 and fixed to the second supportingportion 124 along the same direction, wherein the direction along that theglass module 130 and thebacklight module 140 are fixed to theframe 120 is the normal vector of thedisplay region 132 on the display module. With the needs of product design, the first supportingportion 122 is located on theframe 120 at a position outside that of the second supportingportion 124, so the light can be totally transmitted to theglass module 130 from thebacklight module 140. An opening can be formed at the center of theframe 120, and the light generated by thebacklight module 140 can be transmitted to theglass module 130 via the opening so as to increase the brightness of thedisplay region 132. When the panel module is fixed to theframe 120, theframe 120 can surround the periphery of the panel module, and the panel module must cover the opening to increase the brightness of thedisplay region 132. With the needs of product design, theframe 120 can further include a retainingportion 126 for preventing theglass module 130 from leaving the first supportingportion 122 and for protecting theglass module 130. If theframe 120 does not include the retainingportion 126, the invention can further include adecorative frame 190 illustrated inFIG. 3 . Thedecorative frame 190 is located at the periphery of theglass module 130 and engaged to theframe 120 or thecover 110 to protect the glass plates of theglass module 130 from breakage while being impacted. Theglass module 130 includes a first side and a second side. The first side of theglass module 130 includes thedisplay region 132 and is used to contact the retainingportion 126 or thedecorative frame 190. The second side of theglass module 130 contacts or is fixed to thebacklight 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 theglass module 130 and includes thedisplay region 132. The second side of the panel module is fixed to theframe 120, so as to combine the panel module and theframe 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. - Under the configurations that the
frame 120 has the retainingportion 126, theglass module 130 and thebacklight module 140 of the panel module are both fixed to theframe 120, theframe 120 is engaged to thecover 110, and theglass module 130 is retained by the retainingportion 126, the assembly of the display module can be accomplished. Because the display module is mounted to thecover 110 without screws, thecover 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 inFIG. 1 andFIG. 3 ). When theglass module 130 and thebacklight module 140 of the panel module are just fixed to theframe 120 to form the display module, theframe 120 is the only structure that provides support. Thereby, the display module and thecover 110 can be combined to each other to form thedisplay device 100 with the assistance of the support of theframe 120. - In the embodiment, the first supporting
portion 122 and the second supportingportion 124 can be made of plastics that have buffering effect, so as to provide support to theglass module 130 and thebacklight module 140. The retainingportion 126 can be made of rubber and integrally formed with the first supportingportion 122 and the second supportingportion 124 by co-injection molding. Thecover 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, thecover 110 can also be made of plastics and have integrally formed reinforcing ribs or metal members for improving structural strength. - As shown in
FIG. 4 , the first supportingportion 122 of the embodiment has a first supportingsurface 122 c, and the second supportingportion 124 has a second supportingsurface 124 a. The distance between the first supportingsurface 122 c and thebase plate 112 is longer than that between the second supportingsurface 124 a and thebase plate 112. The orthogonal projection of theperipheral part 134 of theglass module 130 on thebase plate 112 and that of thebacklight module 140 on thebase plate 112 do not overlapped to each other. Therefore, theglass module 130 and thebacklight module 140 that are stacked to each other are respectively fixed to the first supportingsurface 122 c and the second supportingsurface 124 a, wherein theglass module 130 is fixed to the first supportingsurface 122 c with theperipheral part 134, and the glue applied between the panel module and theframe 120 includes epoxy. - Besides, the
sidewall 114 of thecover 110 has afirst fixing portion 114 a, the first supportingportion 122 on theframe 120 has asecond fixing portion 122 d, and thecover 110 can be mounted to theframe 120 by making thefirst fixing portion 114 a and thesecond fixing portion 122 d to be engaged to each other. After thecover 110 is mounted to theframe 120 to form thedisplay device 100, the position of thecover 110 is adjacent to the second side of the panel module, and thecover 110 and theframe 120 both provide support to the panel module so as to improve the structural strength of the display module. After thecover 110 is mounted to theframe 120, thesidewall 114 of thecover 110 will cover the sidewall of theframe 120 to avoid light leakage of the display device. - As shown in
FIG. 4 , when thedisplay device 100 that has backlight is a liquid crystal display device, theglass module 130 of the first embodiment includes afirst glass plate 136, aliquid crystal layer 137, and asecond glass plate 138. Thefirst glass plate 136 is located at the second side of the panel module and fixed to the first supportingportion 122, and theliquid crystal layer 137 is disposed between thefirst glass plate 136 and thesecond glass plate 138. Thesecond glass plate 138 is located at the first side of the panel module for contacting the retainingportion 126 or thedecorative frame 190. Thefirst glass plate 136 and thesecond glass plate 138 can be made of transparent materials with high strength, so as to protect theliquid crystal layer 137 and make the light emitted by thebacklight module 140 suitable to be transmitted to theliquid crystal layer 137 through thefirst glass plate 136. Finally, after theliquid crystal layer 137 processes the light, users can watch the images displayed by the display module through thesecond glass plate 138. - As shown in
FIG. 5 which is a stereoscopic view showing the cover of the invention. Thecover 110 of the invention can further include ahinge module 106. Thehinge module 106 mainly includes abracket 106 a and apivotal portion 106 b. Thebracket 106 a of thehinge module 106 can be fixed to the inner surface of thecover 110 byglue 2, wherein the inner side of thecover 110 is adjacent to the second side of the display module and theglue 2 includes epoxy. Thepivotal portion 106 b of thehinge module 106 can be connected to thebracket 106 a. Thehinge 108 can be pivotally connected to thepivotal portion 106 b. Therefore, thehinge 108 can be mounted to thecover 110 by thehinge module 106 that is fixed to thecover 110. With different designs of products, thepivotal portion 106 b and thebracket 106 a of thehinge 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 thepivotal portion 106 b able to pivotally connect thehinge 108. In order to provide enough mounting strength to thehinge 108 when thehinge 108 is forced in operation, thepivotal portion 106 b and thehinge 108 are generally connected to each other by the screw fastening method. Generally, thebracket 106 a 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. - It can be seen that because the
hinge module 106 is mounted to thecover 110 by gluing thebracket 106 a to thecover 110, the thickness of thehinge module 106 in the display device 100 (i.e., the space between thecover 110 and the display module) is equal to the thickness of thebracket 106 a. The length of screws that are applied to mount thehinge 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, thebracket 106 a of thehinge module 106 of the embodiment is plate-shaped, and a range of the thickness of thebracket 106 a is only 0.8 mm-1.0 mm. Therefore, thebracket 106 a that is fixed to thecover 110 will not influence the whole strength of thedisplay device 100 and can easily reduce the thickness of thedisplay device 100. - As shown in
FIG. 5 , thecover 110 of thedisplay device 100 of the embodiment can further include fourrims 100 a, and therims 100 a can be classified to be two pairs and surround thecover 110. Generally, the two pairs of therims 100 a can be classified into long rims and short rims, and each pair of therims 100 a are parallel to each other. Thebracket 106 a of thehinge module 106 can be substantially parallel to therims 100 a, and therims 100 a 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 thehinge module 106 of the embodiment is not mounted to thecover 110 by the screw fastening method, the length of thebracket 106 a of thehinge module 106 can be longer than half the length of one of therims 100 a so as to increase the mounting stability between thehinge module 106 and thecover 110. In other words, if the length of thebracket 106 a of thehinge module 106 becomes longer, the gluing area and range between thebracket 106 a and thecover 110 relatively increase, and thus the mounting stability between thebracket 106 a and thecover 110 can be increased. When thecover 110 is forced, the force can be transmitted to thehinge 108 via thebracket 106 a and thepivotal portion 106 b, so that thehinge 108 can rotate together with thecover 110 relative to an object. So, the width of the portion of thebracket 106 a that is adjacent to thehinge 108 is very important. Because the portion of thebracket 106 a is the interface via which the force is transmitted from thecover 110 to thehinge 108, the portion of thebracket 106 a bears larger force than other portions. If the width of the portion of thebracket 106 a is longer, the mounting capability of thebracket 106 a is also larger, so as to prevent the defeat that thehinge module 106 separates from thecover 110 during the operation of thehinge 108. Generally, the width of thebracket 106 a is directly proportional to a desired torque of thehinge 108 and the width of the bracket is approximately longer than 25 mm, wherein the width of thebracket 106 a is the width of the end of the bracket that is adjacent to thehinge 108. The desired torque of thehinge 108 is the minimum force that thehinge 108 is necessarily loaded during operation. - The
cover 110 of the embodiment further includes a reinforcingplate 110 a. The reinforcingplate 110 a of thecover 110 can be fixed to the inner side of thecover 110, just like thehinge module 106 does. The reinforcingplate 110 a can be substantially perpendicular to thebracket 106 a, but the configuration between the reinforcingplate 110 a and thebracket 106 a 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 thedisplay device 100, the reinforcingplate 110 a of thedisplay device 100 and thebracket 106 a of thehinge module 106 can also be connected to each other. In other words, the reinforcingplate 110 a and thebracket 106 a can be integrally formed according to the requirements of product design and then fixed to the inner side of thecover 110 to reinforce the strength of thecover 110. In order to take the weight of thedisplay device 100 into consideration, the reinforcingplate 110 a that is fixed to thecover 110 can be, but not limited to, made from an aluminum plate of which the thickness is 0.6 mm. - When the electronic device has a host housing, the
display device 100 of the invention can be connected to the host housing by thehinge 108, so as to make thedisplay device 100 to rotate relative to the host housing. When thedisplay device 100 covers on the host housing, the reinforcingplate 100 a on thecover 110 of thedisplay device 100 will correspond to the palm raise of the host housing, so as to increase the supporting strength between thedisplay device 100 and the host housing and prevent thedisplay device 100 or the host housing from being damaged because users press improper locations. - 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 inFIG. 4 to substitute for theliquid crystal layer 137. Therefore, the panel module only includes theglass module 130, and the supporting member on theframe 120 can support the panel module just by one supporting portion. When the panel module is fixed to the supporting portion of theframe 120, theframe 120 will be the only one structure that supports the panel module. - 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.
- 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.
