BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a flat panel display device, and more particularly, to a frame for a flat panel display device to improve the interchangeability between devices. 
   2. Description of the Related Art 
   In general, a cathode-ray tube (CRT) has been widely used for a monitor of a device, such as a television, a measuring instrument, a data terminal or the like. However, the CRT has become an obstacle to the miniaturization, slimness and lightness of electronic appliances due to the weight and volume thereof. 
   To satisfy the increasing requests for the miniaturization, slimness and lightness of electronic appliances, flat display devices, such as a liquid crystal display (LCD) device, a plasma display panel (PDP), and the like which are substitute for the CRT, have been developed and popularized. 
   Frames for flat panel display devices according to the related art are characterized by each of them being integrally molded. In detail, each of the frames as described above is molded of steel plate such that the size and shape of the frame and the location of a printed circuit board (PCB) are fixed. 
   The frame for the display device is coupled with a rear surface of the display module. A variety of elements for operating the display devices, such as PCB, main board, power board and the like, are mounted to the other side of the frame for the display device. Bosses and coupling holes are formed in the frame for the display device, such that fixing locations for a variety of elements coupled with the frame can be secured. 
   However, since the frame for flat panel display device according to the related art as described above is integrally formed such that the mount locations of respective elements are fixed, the frames should be manufactured differently depending on the types of display modules and the sizes of the PCBs, resulting that frame sharing cannot be achieved. Accordingly, a new metal mold should be manufactured in the development of a new product. As a result, cost and time taken in manufacturing a new metal mold are added whenever a model is changed. Also, since the entirety of the frame is made of the steel plate, a use amount of the steel plate increases, so that manufacturing cost and product weight increase. 
   Additionally, the heavier weight and larger volume of the frame may cause a difficulty in storage and an increase in logistics costs. That is, since the entirety of the frame is integrally molded, increasing space relative to a volume of the frame is needed for storage of the product. 
   SUMMARY OF THE INVENTION 
   Accordingly, the present invention is directed to a flat panel display device and a frame for the same that substantially obviate one or more problems due to limitations and disadvantages of the related art. 
   An object of the present invention is to provide a frame for a flat panel display device on which a variety of sizes and shapes of PCBs can be mounted. 
   Another object of the present invention is to provide a frame for a flat panel display device which can be mounted on a variety of sizes of display modules. 
   A still another object of the present invention is to provide a flat panel display device in which a frame is configured to have a variable horizontal/vertical length and a supporting member involved in the frame is configured to have a variable securing position so as to realize a frame sharing. 
   An even another object of the present invention is to provide a frame for a flat panel display device, which need not to manufacture a new metal mold in the development of a new product anymore, thereby reducing cost and time taken for making metal molds. 
   A further object of the present invention is to provide a frame for a flat panel display device in which steel plate is applied only to chassis parts, reducing the manufacturing cost and the product weight. 
   A still further object of the present invention is to provide a frame for a flat panel display device, which can reduce a logistics cost due to a reduction of the weight and volume of the frame as described above.

   DETAILED DESCRIPTION OF THE INVENTION 
   Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. 
     FIG. 1  is a perspective view showing a coupling structure of a flat panel display device according to the present invention and  FIG. 2  is an exploded perspective view showing a structure of a flat panel display device according to the present invention. 
   Referring to  FIGS. 1 and 2 , the flat panel display device includes a front cabinet  300  forming a front shape of the flat panel display device, a display module  200  coupled to a rear side of the front cabinet  300 , for implementing an image, a frame assembly  100  coupled with one side of the display module  200 , for securing the display module  200  and being mounted with PCB and the like, and a back cover forming a rear shape of the flat panel display device and protecting the display module  200 . 
   In detail, the front cabinet  300  forms the front shape of the flat panel display device, and, at the same time, prevents the display module  200  from being damaged by an external shock. The back cover  400  protects the display module  200  from an external shock and acts as barrier against electromagnetic interference (EMI). 
   The display module  200  is configured to have a substantially rectangular shape, with upper and lower boards attached. Why the display module  200  has a rectangular shape is to implement a preferred wide screen for a user. 
   Also, the frame assembly  100  is coupled with a rear side of the display module  200  so that a fixed position of the display module  200  mounted on the rear side of the front cabinet  300  can be supported. A frame for the flat panel display device according to the present invention has a characteristic that the frame assembly  100  is configured to have an adjustable vertical length so as to be coupled with the display modules  200  having a variety of sizes. 
   Moreover, the frame assembly  100  is provided on one surface thereof with various components, such as a PCB, power board, main board or the like for operating the display device. The frame for the flat panel display device according to the present invention has another characteristic that a vertical frame assembly  120  in  FIG. 3  is configured to move in the left and right directions so as to be coupled with a variety of sizes and shapes of PCBs. 
   Hereinafter, the frame assembly  100  will be more fully described. 
     FIG. 3  is a perspective view showing a structure of a frame for the flat panel display device according to the present invention. 
   Referring to  FIG. 3 , the frame assembly  100  of the flat panel display device includes a first horizontal frame  110  forming an upper end of the frame assembly  100  and having a guide slot along its length, a second horizontal frame  115  forming a lower end of the frame assembly  100  and having a guide slot along its length, at least one of vertical frame assemblies  120  coupled with the first and second horizontal frames  110  and  115 , and a supporting member  150  coupled with the vertical frame assembly  120 , for supporting the secure positions of components which are mounted to the frame assembly  100 . Also, a variety of boards such as a power board  180 , a main PCB  190  or the like are secured to the supporting member of the frame assembly  100 . 
   More particularly, the first and second frames  110  and  115  form the upper and lower ends of the frame assembly  100 , respectively. At least one of the vertical frame assemblies  120  is connected to the guide slots  113  of the first and second horizontal frames  110  and  115 . Since the guide slots  113  run along the lengths of the horizontal frames  110  and  115 , a user can easily adjust the coupling position of the vertical frame assembly  120  according to the sizes and shapes of the components such as a power board  180  or main PCB  190 . 
   Meanwhile, the vertical frame assembly  120  includes a first vertical frame  130  forming an upper part of the vertical frame assembly  120 , and a second vertical frame  140  having one end portion which overlaps the first vertical frame  130  such that the second vertical frame  140  can slide into and withdraw from the first vertical frame  130 . As describes above, the second vertical frame  140  slides into or withdraws from the inside of the first vertical frame  130 , so that it becomes possible to adjust the entire length of the vertical frame assembly  120 . Accordingly, the present invention has an effect that can allow the frame assembly  100  to be mountable to the display modules  200  having various sizes. 
   The vertical frame assembly  120  is connected to the first horizontal frame  110  at one end and to the second horizontal frame  115  at the other end. As described above, the vertical frame assembly  120  is coupled with the guide slot (see  113  of  FIG. 4 ) of the first horizontal frame  110  and the second horizontal frame  115 . Accordingly, the present invention has an effect that the various sizes and shapes of PCBs can be coupled with the frame assembly  100 . Also, since a separate coupling member such as a bolt can secure the vertical frame assembly  120  to the horizontal frames  110  and  115 , the present invention has an advantage of easily fastening and loosening the vertical frame assemblies  120 . 
   While the drawing shows only the three vertical frame assemblies  120 , the present invention is not limited thereto. Preferably, the number of the vertical assemblies  120  can be modified in the scope of the present invention, depending on the numbers and shapes of components to be mounted to the frame assembly  100 . 
   The vertical frame assembly  120  is coupled with one or more of supporting members  150 . More particularly, the first vertical frame  130  and the second vertical frame  140  have rail-shaped insert slots and coupling slots where the supporting members  150  are secured, so that the supporting members can be secured to variable positions. Accordingly, changeability of the coupling position as described above gives an effect that the supporting members  150  can be coupled with a power board  180  and PCB  190  having a variety of sizes and shapes. 
   Each element of the frame assembly  100  will be further described below. 
     FIG. 4  is a perspective view showing the structure of the first vertical frame in the frame for the flat panel display device. 
   Referring to  FIG. 4 , the first vertical frame includes a long rod-shaped frame  111 , bent sections  112  which are formed at both ends of the frame  111  and coupled with the display module  200  for supporting a secure position of the display module  200 , a guide slot  113  formed approximately at the center of the width along the length of the frame  111 , and one or more of coupling holes  114  which are formed at one or two ends of the frame  111  for being coupled with a vertical frame assembly  120  as described below. 
   In particular, the first horizontal frame  110  forms the upper end of the frame assembly  100 . The first horizontal frame  110  is formed of steel plate and has a long rod-like shape. The guide slot  113  is approximately formed at the center of the width along the length of the first horizontal frame  110 . The guide slot  113  is coupled with the vertical frame assembly  120 . That is, the coupling hole  144  of the vertical frame assembly  120  in  FIG. 7  is overlaid on the guide slot  113 , so that the separate coupling members such as bolt and nut can secure the coupling hole  144  to the guide slot  113 . Herein, the guide slot  113  is formed along almost the entire length of the first horizontal frame  111 , so that a user can select the coupling position, as the user desires. 
   Meanwhile, the second horizontal frame  115  forms the lower end of the frame assembly  100 . The second horizontal frame  115  has almost the same shape as the first horizontal frame  110 . Thus, a detailed explanation for the second horizontal frame  115  will be omitted. 
   As described above, the guide slots  113  are formed along the lengths of the first and second horizontal frames  110  and  115 . Since the vertical frame assembly  120  can be freely secured to the guide slots  113  at the desired location, the vertical frame assembly  120  has an effect that can be mounted with a variety of sizes and shapes of PCBs. Furthermore, the vertical/horizontal lengths of the frame and the secure position where the supporting member is secured are changeable, so that the present invention has an effect on the frame sharing. 
     FIG. 5  is a perspective view showing a structure of a first vertical frame of a frame for a flat panel display device according to the present invention,  FIG. 6  is a perspective view of a portion “A” in  FIG. 5 ,  FIG. 7  is a perspective view showing a structure of a second vertical frame of a frame for a flat panel display device according to the present invention,  FIG. 8  is a perspective view magnifying “B” in  FIG. 7 , and  FIG. 9  is a perspective view showing a coupling structure of a first vertical frame in  FIG. 5  and a second vertical frame in  FIG. 8 . 
   Referring to  FIGS. 5 and 6 , the first vertical frame  130  includes a frame  131  forming a main body, a support section  132  protruded downwardly from one end of the frame, for supporting the first vertical frame  130 , and a bent section which is bent at the end of the support section  132  and coupled with the first horizontal frame  110 . 
   More particularly, the first vertical frame  130  is coupled with the second vertical frame  140  to form the vertical frame assembly  120 . Furthermore, the vertical frame assembly  120  is coupled with the first and second horizontal frames  110  and  115  to form the structures of the frame assembly  100 . Of course, it will be apparent that at least one of the vertical frame assembly  120  can be involved in relation with the use of the products. Various components of the display device, such as the PCB  190  or power board  180  will be coupled on the frame assembly  100 . 
   The frame  131  has a receptor  138  substantially shaped in “           ” to accommodate and couple the second vertical frame  140 . That is, the second vertical frame  140  can slide into or withdraw from the receptor  138 , so that the length of the vertical frame  120  can be adjusted.
   One or more of guide rails  137  are arranged along the length of the frame  131  in the inner of the receptor  138 . The guide rail  137  and a guide protrusion  161  run together to ensure a coupling of the first and second vertical frames  130  and  140  and guide the ingress and egress of the second vertical frame  140 . Also, the support section  132  protrudes downwardly from one end of the frame  131 . The support section  132  supports the first vertical  130 , while the first vertical frame  130  is spaced from the first horizontal frame  110  by a distance so that the frame assembly  100  may support the secure position of the display module  200  and protect an interference by the various components and boards involved in the display module  200 . 
   Furthermore, the support section  132  is bent at the end of the support section to form a bent section  133  in which a coupling hole is formed (not shown). As described above, the coupling hole and the guide slot  113  of the first horizontal frame  110  are coupled together by the separate coupling members such as bolt and nut or the like. 
   The frame  131  includes an insert slot  135  into which the supporting member  150  is inserted, and a coupling slot  136  through which a separate coupling member passes for joining together the frame  131  and the supporting member that is inserted into the insert slot  135 . The coupling relation between the first vertical frame  130  and the supporting member  150  will be explained later with reference to  FIG. 13 . 
   Referring to  FIGS. 7 and 8 , the second vertical frame  140  has a shape similar to the first vertical frame  130 . 
   In detail, the second vertical frame  140  includes a frame  141  forming a main body, a support section  142  extending downwardly from one end of the flame  141  to support the second vertical frame  140 , and a bent section  143  which is bent at the end of the support section  142  and coupled with the second horizontal frame  115 . A coupling hole  144  is further formed in the bent section  143  for being coupled with a coupling hole of the second horizontal frame  115 . Furthermore, the frame  141  includes an insert slot  145  into which the supporting member  150  is inserted, and a coupling hole  146  through which a separate coupling member passes for coupling together the frame  141  and the supporting member  150  that is inserted into the insert slot  145 . 
   In more detail, the frame  141  slides into the receptor  138  of the first vertical frame  130 . For this, the width of the frame  141  is preferably the same or slightly less than that of width the receptor  138 . Thus, the second vertical frame  140  slides into or withdraws from the first vertical frame  130 , so that the entire length of the vertical frame assembly  120  can be adjusted. 
   Meanwhile, the guide member  160  is coupled to the frame  141  at the opposite end of the support section  142 . 
   Particularly, the guide member  160  coupled to at least one side of the frame  141  has a substantially rectangular shape. The guide member  160  has at least one guide protrusion  161  at one side thereof. The guide protrusions  161  are supposed to be in harmony with the guide rails  137  of the first vertical frame  130 , and thereby slide into the guide rail  137 . As above, since the guide protrusion  161  is in harmony with the guide rail  137 , the operating action of the first and second vertical frame  130  and  140  can be credibly achieved. A first coupling member  162  and a second coupling member  163  allow the guide members  160  to be coupled on the second vertical frame  140 . The relation between the guide member  160  and the second frame  140  will be more minutely explained below. 
   Referring to  FIG. 9 , an assembling process of the vertical frame assembly  120  will be described as follows. 
   First, the second vertical frame  140  and the guide member  160  are coupled together. In detail, the guide member  160  has first and second coupling holes  164  and  165 , wherein first and second coupling members  162  and  163  secure the guide member  160  to the second vertical frame  140 . 
   The first coupling hole  164  is formed such that only a thread section of the first coupling member  162  can penetrate into the first coupling hole  164 . In other words, a head of the first coupling member  162  is partially protruded from the surface of the guide member  160 . While, the second coupling hole  165  is configured to accept even the head together with the thread section of the second coupling member  163 . That is, the second coupling hole has a stair-like, cylindrical shape that can accept even the head of the second coupling member  163 . Accordingly, the head of the second coupling will not protrude upwardly. 
   According to the structures describes above, the first coupling member  162  acts as a stopper which secures the guide member  160  to the second vertical frame  140 , and at the same time, prevents the second vertical frame  140  from sliding into the first vertical frame  130  to an excessive degree. 
   Next, the second vertical frame  140  coupled with the guide member  160  is inserted into the first vertical frame  130 . Herein, the guide protrusion  161  of the guide member  160  is designed to fit to the guide rail  137  of the first vertical frame  130 , prevent the second vertical frame  130  from being derailed, and at the same time, guide the ingress and egress of the second vertical frame  140 . Additionally, the first coupling member  162  prevents the second vertical frame  140  from excessively sliding into the first vertical frame. 
   Based on the structures described above, provided is a frame for the flat panel display device which can be applied to a variety of sizes of display modules. Furthermore, the present invention has an effect that realizes the frame sharing, and thereby reduces the cost and time taken in making a new mold for the development of a new frame. 
     FIG. 10  is a perspective view showing a structure of a supporting member of a frame for a flat panel display device according to the present invention. 
   Referring to  FIG. 10 , a supporting member  150  includes a first plane  151  and a second plane  152  which have a stair-like shape, a separation protector  153  which protrudes upwardly from the first plane  151  and goes into the insert slots  135  and  145  of the vertical frame assembly  120 , and a position securing section  154  which protrudes upwardly from the second plane  152  to a certain extent and supports the secure positions of boards such as a PCB mounted to the supporting member  150 . 
   Also, the first plane  151  has a first coupling hole  155  which is connected to a coupling hole  136  or  146  of the vertical frame assembly  120 , and the second plane  152  has a second coupling hole  156  which is connected to main board  180 , PCB and the like. 
     FIG. 11  is a perspective view showing a coupling structure of a horizontal frame, a vertical frame and a supporting member. 
   Referring to  FIG. 11 , a guide slot  113  of the first horizontal frame  110  and a coupling hole of the first vertical frame, and a guide slot of the second horizontal frame  115  and a coupling hole  144  of the second vertical frame are coupled together by each coupling members  171 . 
   Herein, the guide slot  113  is formed in a lengthwise direction of the horizontal frames  110  and  115 , so that a vertical frame assembly can be connected to any position of the horizontal frame. Preferably, the above coupling between the horizontal frames  110  and  115 , and the vertical frame assembly  120  can be performed in a way that they are coupled together at a predetermined position by a jig. By the method described above, the horizontal frames  110  and  115 , and the vertical frame assembly  120  can be exactly joined at a desired location. In the case of applying the frame assembly  100  to even a variety of sizes of display module or PCB, the present invention has the advantage of realizing the frame sharing only by selecting the coupling position between the horizontal frames  110  and  115 , and the vertical frame assembly  120  using the jig. 
   Meanwhile, a process by which a supporting member  150  is coupled with the vertical frame assembly  120  is as follows. 
   First, a separation preventing member  153  of the supporting member  150  is inserted into the insert slots  135  and  145 . In detail, the supporting member  150  is erected vertically, so that the separation preventing member  153  can be parallel to, and then inserted into the insert slots  135  and  145 . Next, with the separation preventing member  153  inserted, the supporting member  150  is downwardly pressed such that the first coupling hole  155  contacts the coupling slots  136  and  146 . And then, the supporting member  150  is securely coupled with the vertical frame assembly  120  using separate bolt  173  and nut  174  which penetrate through the first coupling hole  155  and coupling slots  136  and  146 . 
   Herein, since the insert slots  135  and  145 , and the coupling slots  136  and  146  are formed in a lengthwise direction of the vertical frame assembly  120 , the supporting member  150  can be coupled at any position of the vertical frame assembly  120 . 
   According to the structures described above, the present invention has an effect that a variety of sizes and shapes of components, such as PCB, main board and the like can be coupled with the frame assembly  100 . 
     FIG. 12  is a perspective view showing a movement of a frame assembly of a flat panel display device according to the present invention. 
   Referring to  FIG. 12 , the frame assembly  100  of the flat panel display device according to the present invention, includes a first horizontal frame  110  forming an upper end of the frame assembly  100 , a second horizontal frame  115  forming a lower end of the frame assembly  100 , and one or more of vertical frame assemblies  120  which are located between the first horizontal frame  110  and the second horizontal frame  115 . The vertical frame assembly  120  includes a supporting member  150  on which a PCB, a power board and the like are mounted. 
   In detail, the first and second horizontal frame  110  and  115  have a longitudinal guide slot  113  with which the upper and lower ends of the vertical frame assembly  120  are coupled. Since the vertical frame assembly  120  can be coupled with any position on the guide slot  113 , PCBs having various sizes and shapes can be coupled with the vertical frame assembly  120  by selecting their secure positions. 
   Meanwhile, the vertical frame assembly  120  includes a first vertical frame  130 , and a second vertical frame  140  which slides into and withdraws from a receptor  138  of the first vertical frame  130 . As above, the second vertical frame  140  slides into and withdraws from the first vertical frame  130 , so that the entire length of the vertical frame assembly  120  can be adjustable. Accordingly, provided is the frame assembly  100  which can be applied to various display modules having different sizes. 
   Additionally, since the vertical frame assembly  120  has insert slots  135  and  145  and coupling slots  136  and  146  formed in a lengthwise direction thereof such that the supporting member  150  may be coupled at any position in which the insert slots  135  and  145  and the coupling slots  136  and  146  are formed, PCBs in various sizes and shapes may be coupled to the vertical frame assembly  120 . 
   According to the present invention, it can be shown that the length and position of the vertical frame assembly are changeable, while the length of the vertical frame assembly is unchanged but the position of the vertical frame assembly may be changeable in harmony with the change of the length of the vertical frame assembly. However, the present invention is not limited to the above structure. In other words, it will be also possible to propose a modification that the length of the horizontal frame is changeable from the spirit of the present invention. However, since the object of changing the length of the horizontal frame can be attained by allowing the display module to have a structure supporting the horizontal frame instead of changing the length of the horizontal frame, there is not so much need to do so. 
   Also, while the present invention shows and describes that the secure position and the length of the vertical frame assembly are variable in harmony with the horizontal frame assembly, the present invention is not limited thereto. For example, it can be easily supposed that the spirit of the present invention can be equally implemented by changing the secure position and length of the horizontal frame assembly. 
   Furthermore, the horizontal frame assembly can be formed only at any one of upper and lower sides of the display module. In this case, it is possible to supply an intrinsic securing unit supporting the horizontal frame assembly to a side where the horizontal frame assembly is not provided. 
   As described above, according to the present invention, PCBs and display modules in a variety of sizes and shapes can be mounted to the frame for the flat panel display device. Moreover, since the horizontal and vertical lengths of the frame and the secure position of the supporting member involved in the frame are changeable, the frame sharing is possible. Also, through the frame sharing, the cost and time taken in making a new mold for the development of a new frame can be reduced. Furthermore, since only the chassis of the frame is made of steel plate, a use amount of the steel plate is saved and according the manufacturing cost and product weight are reduced, thereby obtaining effects of easy storage and reduction in logistics cost. 
   It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
