## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a display device and a wall mount module and, more particularly, to a display device and a wall mount module capable of being thinned and being assembled conveniently.
2. Description of the Prior Art
As display technology advances, it is reasonably expected that a TV wall consisting of a plurality of display devices will be developed in the future for satisfying visual requirements. In general, the display device is usually designed as a stand-alone device, i.e. each display device is equipped with individual power supply unit (PSU) and power cable. When a plurality of display devices are used to form a TV wall, the construction may be inconvenient due to the power cable. Furthermore, the display device is mostly hanged on the wall by a wall mount module. The conventional wall mount module has a specific thickness, such that the display device cannot be attached to the wall as close as possible. Accordingly, the visual effect of the display device will be influenced.
SUMMARY OF THE INVENTION
The invention provides a display device and a wall mount module capable of being thinned and being assembled conveniently, so as to solve the aforesaid problems.
According to an embodiment of the invention, a display device comprises a device body and a wall mount module. Aback of the device body has a first conducting pillar and a second conducting pillar. The wall mount module comprises a first bracket, a second bracket, a first cover, a second cover, a first conducting member, a second conducting member and a power cable. The first cover is disposed on the first bracket and the second cover is disposed on the second bracket. The first conducting member is disposed between the first cover and the first bracket and the second conducting member is disposed between the second cover and the second bracket. The power cable is connected to the first conducting member and the second conducting member. The first bracket has a first hole formed thereon and the first conducting member is exposed through the first hole. The second bracket has a second hole formed thereon and the second conducting member is exposed through the second hole. The first conducting pillar passes through the first hole and the second conducting pillar passes through the second hole, such that the device body is fixed on the first bracket and the second bracket, the first conducting pillar abuts against the first conducting member, and the second conducting pillar abuts against the second conducting member.
In this embodiment, the back of the device body may further have a recess, and the first bracket and the second bracket are accommodated in the recess.
According to another embodiment of the invention, a wall mount module comprises a first bracket, a second bracket, a first cover, a second cover, a first conducting member, a second conducting member and a power cable. The first bracket has a first hole formed thereon and the second bracket has a second hole formed thereon. The first cover is disposed on the first bracket and the second cover is disposed on the second bracket. The first conducting member is disposed between the first cover and the first bracket and exposed through the first hole. The second conducting member is disposed between the second cover and the second bracket and exposed through the second hole. The power cable is connected to the first conducting member and the second conducting member.
As mentioned in the above, the power cable of the invention is connected to the conducting member on the bracket of the wall mount module. Therefore, when the conducting pillar passes through the hole on the bracket correspondingly and then abuts against the conducting member, the power cable may supply power to the device body through an electrical contact formed between the conducting member and the conducting pillar. The user may fix the bracket of the wall mount module on a wall first and then insert the conducting pillar of the back of the device body into the hole on the bracket correspondingly, such that the display device is hanged on the wall. Accordingly, the power cable will not interfere with the assembly of the device body and the wall mount module. Furthermore, since the invention hides the conducting member in the cover, the total thickness of the wall mount module will not increase, such that the invention is capable of being thinned favorably. Moreover, when the display device is hanged on the wall, the invention may dispose the bracket of the wall mount module in the recess of the back of the device body, so as to attach the display device to the wall as close as possible. Accordingly, the invention may enhance the visual effect of the display device.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

Furthermore, the power cable 136 is connected to an adapter 140, wherein the adapter 140 may convert alternating current (AC) to direct current (DC) and then transmit direct current to the first conducting member 132 and the second conducting member 134 through the anode end and the cathode end of the power cable 136, respectively. In this embodiment, the first conducting member 132 and the second conducting member 134 may be made of conducting metal, wherein the first conducting member 132 may have a first resilient portion 1320 and the second conducting member 134 may have a second resilient portion 1340.
Then, the first conducting member 132 and the second conducting member 134 may be disposed in the first cover 128 and the second cover 130, respectively, as shown in FIG. 7. In this embodiment, the first conducting member 132 and the second conducting member 134 may be fixed in the first cover 128 and the second cover 130, respectively, by welding, engagement or other fixing manners.
Then, the first cover 128 may be disposed on the first bracket 120 and the second cover 130 may be disposed on the second bracket 122, as shown in FIG. 8. At this time, the first conducting member 132 is disposed between the first cover 128 and the first bracket 120, and the second conducting member 134 is disposed between the second cover 130 and the second bracket 122. In this embodiment, the first cover 128 may have a plurality of first engaging portions 1280 and the second cover 130 may have a plurality of second engaging portions 1300. As shown in FIG. 9, the first cover 128 may be engaged with an end of the first bracket 120 by the first engaging portions 1280 and the second cover 130 may be engaged with an end of the second bracket 122 by the second engaging portions 1300. It should be noted that the first cover 128 and the second cover 130 may also be disposed on the first bracket 120 and the second bracket 122, respectively, by other manners (e.g. adhesion, screws, etc.) besides engagement.
In this embodiment, opposite sides of the first bracket 120 have a first hole 1202 and a third hole formed thereon and opposite sides of the second bracket 122 have a second hole 1222 and a fourth hole 1224 formed thereon. As shown in FIG. 9, when the first cover 128 and the second cover 130 are disposed on the first bracket 120 and the second bracket 122, respectively, the first resilient portion 1320 of the first conducting member 132 is exposed through the first hole 1202 of the first bracket 120 and the second resilient portion 1340 of the second conducting member 134 is exposed through the second hole 1222 of the second bracket 122.
When a user wants to hang the display device 1 on the wall 3, the user may use a plurality of screws 142 to fix the third bracket 124 and the fourth bracket 126 of the wall mount module 12 onto the wall 3, as shown in FIG. 3. Then, the user may insert the first conducting pillar 102, the second conducting pillar 104, the third conducting pillar 106 and the fourth conducting pillar 108 of the back 100 of the device body 10 into the first hole 1202, the second hole 1222, the third hole 1204 and the fourth hole 1224 of the first bracket 120 and the second bracket 122, respectively, so as to fix the device body 10 on the first bracket 120 and the second bracket 122.

After assembling the device body 10 with the wall mount module 12, the first bracket 120 and the second bracket 122 of the wall mount module 12 may be accommodated in the recess 110. When the device body 10 is hanged on the wall 3 by the wall mount module 12, the device body 10 may be attached to the wall 3 as close as possible, so as to enhance the visual effect of the display device 1.
As mentioned in the above, the power cable of the invention is connected to the conducting member on the bracket of the wall mount module. Therefore, when the conducting pillar passes through the hole on the bracket correspondingly and then abuts against the conducting member, the power cable may supply power to the device body through an electrical contact formed between the conducting member and the conducting pillar. The user may fix the bracket of the wall mount module on a wall first and then insert the conducting pillar of the back of the device body into the hole on the bracket correspondingly, such that the display device is hanged on the wall. Accordingly, the power cable will not interfere with the assembly of the device body and the wall mount module. Furthermore, since the invention hides the conducting member in the cover, the total thickness of the wall mount module will not increase, such that the invention is capable of being thinned favorably. Moreover, when the display device is hanged on the wall, the invention may dispose the bracket of the wall mount module in the recess of the back of the device body, so as to attach the display device to the wall as close as possible. Accordingly, the invention may enhance the visual effect of the display device.
