The present invention relates to a flat panel display device, and more particularly, to an installation apparatus for conveniently installing a flat panel display device and a flat display device in which the internal heat of the flat display device is quickly radiated to the outside to improve the operational reliability of the flat display device. It is about.

Unlike general cathode ray tubes, a flat panel display device is a device in which an emission state of each pixel is implemented differently and forms an image as a whole by a driving circuit arranged in a matrix form. Unlike the cathode ray tube, such a flat panel display device has a small volume, so that the space occupied in a narrow indoor space is small, and thus the use of the flat display device is increased. The flat panel display module applied to the flat panel display device may be a liquid crystal display (LCD), a field emission display (FED), or a plasma display panel (PDP) according to a driving method thereof. And an electroluminescence (EL) display device. Although the flat display device manufactured by these display modules is small in volume, it is possible to pursue user convenience. However, since a large number of heating parts are integrated and manufactured in a narrow flat interior space, Getting heat out is an important challenge.

In particular, since the PDP device generates an image due to the discharge of discharge gas and generates high temperature heat due to electric components, etc., if such heat is not released quickly, the PDP device may cause malfunction or failure. Is the reality. Of course, the flat panel display module driven in another way, the heat dissipation performance of the device limits the performance.

In order to solve the problems related to the cooling of the flat panel display device, a conventionally applied method is to attach a relatively large size heat sink to the back surface of a specific heating part that generates a large amount of heat to cool a specific part, There is a method of drilling a plurality of holes in the cover of the display device to allow air to communicate with the inside and outside of the flat display device. However, this method can expect a cooling effect on a specific part that generates high heat, but the problem that the device does not operate stably because the process of dissipating heat collected in the internal space of the device to the outside is not performed smoothly. have.

In order to improve the above method, an axial fan is installed from the middle of the back cover to the rear in a direction orthogonal to the forming direction of the flat display device, thereby forcibly discharging the high temperature air inside the device to the rear of the display device. It has been applied. However, although this method can increase the efficiency of the heat accumulated inside the device to the outside, not only does a lot of noise occur during the operation of the air discharge, but also a few dozens between the back and the wall of the device to release the air. There is a problem that a spacing of more than a centimeter must be provided. In addition, there is a problem in that the width of the flat panel display module becomes thick due to the distance between the axial fan and the flat panel display module and the self-distance of the axial fan to install the axial fan to suck the air inside the device.

In addition, a general flat display device is installed parallel to the wall to allow a user to view more conveniently. In view of this, the flat display device is a hole in the wall to connect the wall flat display device with a fastening member such as a bolt Has come.

However, such a method requires a process of processing a hole in a strong member such as a concrete wall, and there is a problem of permanent damage to the wall. And because a separate tool for processing holes is required, there was a problem that the installation worker who can install it visits every house to install a flat display device. In addition, the flat display device once installed has a problem causing a lot of inconvenience in use because the movement is unnatural.

The present invention is proposed to improve the above-mentioned problems, the flat display device can be thinner and simpler while obtaining a sufficient heat dissipation effect, the flow noise can be minimized, the freedom of installation of the flat display device is improved And a flat display device that increases the strength of the back cover.

In addition, the structural change of the flat panel display device allows the flat panel display device to be used by being completely in contact with the wall itself, so that the user can install the flat panel display device on the wall by using the flat display device. Suggest.

In addition, even if the flat display device is not fixed to the wall, the present invention proposes an installation apparatus of the flat display device to obtain the convenience of viewing and enhancement of the utilization of the interior space as if fixed to the wall.

A flat display device according to the present invention includes a flat display module; A back cover protecting a rear of the flat panel display module; And an opening provided at an edge portion of the back cover to communicate with the inside and the outside of the back cover so that a rear surface of the back cover may be mounted in contact with a wall surface.

According to another aspect, an installation apparatus of a flat display device according to the present invention may include: a support part connected to the flat display device and extending downward; And a bottom portion formed at a lower end of the support portion, wherein the bottom portion extends rearward from a center of gravity of the flat panel display device to a position of an interval between rear ends of the flat panel display device.

According to another aspect, an installation apparatus of a flat display device according to the present invention may include: a support portion extending downward in a state of being coupled to the flat display device; And a bottom portion formed at a lower end of the support portion, and the length of the bottom portion in front and rear is shorter than the length of the support portion.

According to yet another aspect, an installation apparatus of a flat display device of the present invention includes: a support portion extending downward in a state of being coupled to the flat display device; A bottom portion formed at a lower end of the support portion; And an extended bottom part extending rearward of the bottom part and freely moving forward by an external force.

According to the present invention, it is possible to obtain an advantage that the cooling efficiency of the flat panel display device is improved, the flow noise is reduced, the installation can be more freely without interrupting the installation of the flat panel display device, and the operation reliability in the operation of the fan is improved. In this case, the cost can be reduced and the degree of freedom of installation of the flat panel display device can be increased by the installation apparatus of the flat panel display device.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the spirit of the present invention is not limited to the embodiments presented, and those skilled in the art who understand the spirit of the present invention can easily suggest other embodiments falling within the scope of the same idea, It is said to be included in the range.

1 is a perspective view of a flat panel display device according to the present invention.

Referring to FIG. 1, the flat panel display device 1 of the present invention includes a flat panel display module 2, a front cover 3 that supports and protects the front of the flat panel display module 2, and a flat panel display module 2. A back cover 4 is provided to support and protect the rear of the back panel). In addition, a back cover side opening portion 5 through which hot air from inside the flat panel display device 1 is discharged is formed at an upper edge of the belly cover 4. The back cover side opening 5 is preferably provided in a structure in which a plurality of slits are aggregated so that the strength reduction of the back cover 4 does not occur. In other words, the back cover side opening portion 5 refers to a portion where the hot air is discharged inside the flat panel display device 1 as a whole, and the inner area thereof is provided in the form of a plurality of slits.

The flat panel display module 2 may be a module in which pixels are arranged and operated in a matrix form such as a liquid crystal display, a field emission display, a plasma display panel, and an electroluminescence display. A PDP module that generates relatively high heat as compared to the device may be exemplified.

The front cover 3 and the back cover 4 are an article that partitions the exterior and the interior and protects the components mounted therein while the flat display module 2 is accommodated in the interior space as a whole. Although the cover 3 and the back cover 4 are provided as separate articles and described as an aspect in which the two are combined, the cover 3 and the back cover 4 may be provided in any other form. For example, it is also possible for the front cover 3 and the back cover 4 to be provided as a single article. However, it is natural that the front cover 3 protects the front of the flat display device and the back cover 4 is used for protecting the rear of the flat display device. In addition, a predetermined gap is provided between the inner surface of the back cover 4 and the plurality of heating parts provided on the rear surface of the flat panel display module 2, and through the gap, air flows to cool the heating parts. Naturally, it is discharged through the back cover side opening (5).

The operation of the present invention cooling apparatus will be described with reference to the perspective view of the flat panel display apparatus described above.

When the flat panel display device 1 is operated, a lot of heat is generated in the flat panel display module 2. In particular, the heat generated from the heat generating parts of the rear surface of the flat panel display module 2 is cooled by air introduced from the outside. After that, the heated air is moved upward and then discharged to the outside through the back cover side opening 5. Since the air inside the flat panel display device can be discharged by natural convection in which the heated air moves upward, the cooling effect can be further enhanced. In order to maximize the cooling effect by natural convection as described above, air introduced into the flat display apparatus 1 is introduced into the inside through almost the entire area of the lower surface of the flat display apparatus 1, thereby flat display. It is preferable that the cooling efficiency is further improved by passing through the rear part of the module 2 as a whole. Of course, the part to which the stand is fixed may prevent air from flowing in for stable installation of the stand.

In addition, the back cover side opening 5 is provided at an inclined portion of the edge of the back cover 4 so that the hot air is discharged as it flows (upward direction), thereby making it possible to smoothly flow the hot air. have.

Of course, since the front portion of the flat panel display module 2 is exposed to the outside, heat generated in the front portion of the flat panel display module 2 can be quickly released by the natural convection of the outside air.

2 is a partially cutaway perspective view of a portion of an upper surface of a back cover of the flat display device of the present invention.

Referring to FIG. 2, a cross flow fan 7 is installed inside the upper surface of the back cover 4 in the longitudinal direction of the display device. By installing the cross flow fan 7 as described above, the upper surface portion of the back cover 4 provides a gap in which hot internal air is discharged to the outside. Since hot air can be discharged through the upper surface of the back cover 4 having a long length, the air discharging process becomes easier, and thus the flow resistance and noise of the air are reduced, and the heat radiation efficiency of the hot air is increased. Can be obtained.

The configuration of the cross flow fan 7 will be described in more detail. The crossflow fan 7 partitions the crossflow fan impeller 10 at a predetermined interval between the crossflow fan impeller (see 10 in FIG. 3) and the crossflow fan impeller 10 provided in the left and right lengthwise direction of the back cover 4. And a circular plate 11 for reinforcing the strength of the crossflow fan impeller 10. In addition, one side of the cross flow fan 7 is further formed with a drive shaft 15 and a motor 14 connected to the drive shaft 15, so that the rotational force of the motor 14 is transmitted to the cross flow fan 7. .

In addition, the crossflow fan impeller 10 is entirely accommodated in the housing 18 to guide the flow of air during rotation of the crossflow fan impeller 10, wherein the housing 18 is a crossflow fan impeller 10. Scroll 12 is formed on one side spaced forward and a stabilizer 13 is formed on the other side spaced apart to stabilize the flow of air. The scroll 12 lies in front of the crossflow fan impeller 10 and the stabilizer 13 lies behind the crossflow fan impeller 10 so that the crossflow fan impeller 10 is clockwise relative to the drawing. Will rotate.

Referring to the cross-sectional view taken along the line II ′ of FIG. 1 shown in FIG. 3, the action of discharging hot air by the crossflow fan 7 will be described in detail.

After the crossflow fan 7 is rotated in the clockwise direction as described above, the air in the space inside the back cover 4 is moved upward and moved along the scroll 12, and then the back cover side. It is discharged to the outside through the opening 5.

As described, since the crossflow fan 7 is provided to be substantially long at the entire length in the longitudinal direction of the upper surface of the back cover 4, a large amount of hot air can be discharged. Of course, if the size of the screen is small and the cross flow fan 7 does not need to be provided for the entire length, the back cover side opening 5 and the cross flow fan 7 may be provided only by a specific length. Thus, by providing a large discharge area of the high-temperature air can reduce the disturbance in the discharge of air, thereby obtaining the advantage of reducing the flow resistance and noise of the air.

In addition, since the hot air is discharged through the upper surface of the back cover 4 and is not discharged to the rear, it is necessary to provide a separate gap for the smooth discharge of air to the gap portion between the back surface and the wall surface of the back cover 4. none. Therefore, the flat panel display device of the present invention can be completely attached to the wall by a fastening member such as a screw, and the like, and thus, an advantage of occupying a narrow space can be obtained. Since the flat display device can be installed in close contact with the wall, high convenience in installation can be obtained, which will be described in more detail by the installation apparatus of the flat display device shown in FIG.

4 is a rear view of the flat panel display device for explaining the operation of the cooling device of the flat panel display device according to the present invention.

Referring to FIG. 4, the back cover 4 is further provided with a side suction port 16 for introducing air into the inner space of the back cover 4 in addition to the back cover side opening 5.

The side suction port 16 is formed at an inclined portion of the lower edge of the back cover 4 to allow external low temperature air to be sucked upward into the internal space of the flat panel display device. Of course, the air sucked through the side suction port 16 is air sucked to compensate for the air discharged through the back cover side opening 5, and the negative pressure generated by natural convection and the back cover side opening ( 5) Air sucked to compensate for negative pressure by air discharged through 5).

The air sucked through the side suction port 16 is sucked into the crossflow fan 7 after the high heat of a plurality of parts provided on the rear surface of the flat display module 2 is cooled as a whole, and thereafter, the back cover side opening part. (5) is discharged through the process. In the drawings, arrows indicate the flow direction of air.

On the other hand, among the components of the flat panel display module 2, in particular, a component (for example, a power supply) that generates high heat, and a component (for example, a TCP chip (Tape Carrier Package Chip)) is required.

In order to satisfy such component-specific operating conditions, it is preferable that the components requiring thermal stability are formed at adjacent positions of the side suction holes 16 to be quickly cooled by cold air introduced from the outside. In addition, in the case of a component in which a large amount of heat is generated, it is preferable that the generated heat is formed at an adjacent position of the crossflow fan 7 so that the generated heat can be quickly discharged to the outside without affecting other circuit parts.

As described above, since the fan can be placed on one of the edges of the back cover 4 by the cooling device according to the present invention, the heat dissipation performance of the hot air inside the back cover is further improved, and the operation of the cooling device is further improved. It is possible to obtain the advantage that the reliability of the image is improved. And since there is no separate opening through which air is introduced on the back of the back cover 4, the strength of the back cover 4 can be obtained, thereby increasing the thickness of the material forming the back cover 4. As a result, the material cost can be reduced.

Meanwhile, a stand supporting the flat panel display device is coupled to a predetermined position under the flat panel display device. In order to allow the stand to be coupled to the flat panel display device, the support part 20 and the support part constituting a part of the stand may be combined. A fastener 21 is further provided for coupling 20 to the flat panel display device. The stand is to be provided in an optimal state to the flat panel display device according to the present invention is provided in a special shape and structure, which will be described in detail below.

FIG. 5 is a side view of the mounting apparatus of the flat panel display device according to the present invention, with reference to FIG.

First, the mounting apparatus of the flat panel display apparatus may be installed while the rear surface of the flat panel display apparatus 1 is almost in contact with the side wall 50 while the weight thereof is supported by the lower surface wall 51. This is because there is no gap between the rear surface of the flat panel display device 1 and the side wall 50 because there is no opening at the rear of the flat panel display device 1 for intake and discharge of air. When the flat panel display device 1 is installed as described above, the flat panel display device 1 may be placed at a relatively high position of the side wall 50 while being supported on the bottom surface.

In general, flat display devices have a risk of falling back and forth, so that the bottom portion of the stand must be further lengthened in the front and rear directions so that the flat display device is placed at a high position. For this reason, the stand becomes large, which causes undesirable packaging / transporting / transporting / material cost problems due to the aesthetic aspect of the user and the excessive size of the product. Due to such a problem, when the flat display device is to be installed at a high position of the side wall, it has adopted a method of directly supporting the side wall instead of supporting the bottom surface.

In detail, the flat display device 1 according to the present invention has no air flow through the rear wall of the back cover 4 and air flows in and out through the edge of the back cover 4. The cover 4 may be installed in a state in which it is almost in contact with the side wall 50. When the rear surface of the flat panel display device 1 is installed in the state in which the side wall 50 is supported, the flat panel display device 1 has the bottom portion extending from the rear without any risk of falling backward. The length of 30) can be significantly reduced. In conclusion, even if the flat display device 1 is installed at a high position of the indoor space because the length of the stand 20 of the stand is long, the bottom portion 30 that supports the support 20 is only forward. It does not have to extend and the length to the rear does not extend. Therefore, in fact, the total extension of the bottom 30 in front and rear is not so long.

In addition, when the flat panel display device 1 is installed at a high position of the indoor space, what is observed by the user may be seen to be supported by the side wall 50 because it is mounted at a high position of the indoor space. May be supported with respect to the lower surface wall 51. Of course, since the bottom portion 30 is supported on the lower surface wall 51, there is no need to process a separate hole for inserting a screw into the side wall 50, and the user may conveniently install it. have.

According to such an installation apparatus, even when the flat display device is installed at a relatively high position in the room, a screw or the like does not need to be fixed to the side wall, and the user can conveniently watch the flat display device as if it is fixed to the wall. .

As a method of maximizing the advantages of the installation apparatus of the flat panel display device as described above, when the rear end (ER) of the bottom portion 30 is based on a vertical line, the center of gravity of the flat panel display device ( It only needs to extend rearward enough to lie in the gap between the Center of Gravity (CR) and the rear end (W) of the flat panel display. This is not preferable in appearance because the flat display device is naturally inclined rearward when the rear end of the bottom part is in front of the center of gravity of the flat display device, and the rear end of the bottom part is behind the rear end of the flat display device. This is because the rear surface of the flat panel display device may not contact the side wall 50 when it is extended to the maximum, and thus the advantages of the flat panel display device of the present invention cannot be maximized.

In addition, another method for maximizing the advantages of the installation apparatus of the flat panel display device of the present invention, the length (l1) of the support portion 20 for providing the vertical length of the stand of the installation apparatus of the present invention is the bottom portion ( It is possible to make it longer than the front-back length l2 of 30). In this way, the flat panel display device 1 can be placed above a certain height in the side wall 50, and as a result, can be seen by the user as being actually fixed to the side wall 50. In addition, such a configuration can be provided in close contact with the side wall surface 50 of the indoor space, such as the flat panel display device of the present invention, it can be provided only in the situation that there is no risk of falling backwards.

While the user's satisfaction is improved by the installation apparatus of the flat panel display device as described above, there is an advantage that it can be stably mounted at a convenient location for viewing without leaving any marks on the walls of the room.

6 is a perspective view of a mounting apparatus of a flat panel display device illustrating another embodiment of the present invention.

Referring to FIG. 6, in the installation apparatus according to the present exemplary embodiment, a support part 20 for supporting a flat panel display device and a bottom part 40 for supporting the support part 20 are provided below. And the rear of the bottom portion 40 is further provided with an extended bottom portion 41 is free to move back and forth. The extended bottom portion 41 is an article whose position can be supported by the elastic force of the elastic member installed inside the bottom portion 40, and when pushed forward from the rear by an external force, it is naturally pushed forward. And, when the external force is removed, it can project outward, ie backward.

Therefore, when the flat panel display device is installed in close contact with the side wall, the rear portion of the bottom portion 40 is brought into closer contact with the side wall 50, so that the extended bottom portion 41 is moved forward. When the flat panel display device is not supported on the wall and is placed inside the interior space without any intervention of a supporting structure such as a side wall, the extended bottom portion 41 may protrude rearward. In this case, it will be easily guessed that the back conduction of the flat panel display device is prevented by the extended bottom part 41.

As such, the installation apparatus of the flat display device, in particular, the extended bottom is moved forward and backward, so that the user can be supported by the installation apparatus without any support structure in the center of the indoor space when the user desires, or the flat display When the device is supported by the side wall 51 and is installed in close contact with the side wall 50, the extension bottom part 41 is placed in a forwardly moved state so that there is no interference in the installation of the flat panel display device. You may.

7 and 8 are cross-sectional views taken along line II ′ of FIG. 6, and FIG. 7 illustrates a state in which the extended bottom portion is extended rearward, and FIG. 8 illustrates a state in which the extended bottom portion is contracted forward.

7 and 8, the inside of the bottom portion 40 has a predetermined guide groove 43 in which the elastic member 42 is accommodated, and the guide groove 43 has the extension bottom portion 41. Simultaneously perform the movement to guide the forward and backward movement of

According to the present embodiment, the flat panel display device can be installed in close contact with the wall surface simply without any structure such as a screw to be integrally provided on the wall surface when the flat panel display device is installed on the wall. In addition, since the flat display device can be supported while being supported on the floor without leaving any permanent change on the wall, the visual satisfaction of the user can be enhanced and the convenience of moving the flat display device can be obtained. .

The present invention may also have other embodiments, for example, in a state in which the length of the support is shorter than the length of the bottom, the bottom may be placed in the cabinet rather than the floor of the indoor space. Even in this case, the flat panel display device may be installed on the wall and may be seen by the user.

According to the present invention, the flat panel display device can be made thinner and simpler while obtaining sufficient heat dissipation effect, the flow noise can be minimized, the freedom of installation of the flat panel display device can be improved, The advantage of increasing the strength can be obtained.

In addition, the structural change of the flat panel display device allows the flat panel display device to be completely adhered to the wall itself so that the flat display device can be conveniently installed on the wall by the user, and the utilization of the indoor space is enhanced. have. In addition, since the user can conveniently move the installation position of the flat display device as well as the state of being perfectly mounted on the wall, the user's convenience can be further improved.
