BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The invention relates to a display, and more particularly to a display with replaceable stand.  
           [0003]    2. Description of the Related Art  
           [0004]    As display technology progresses, displays have become compacter and lighter. Therefore, the flat display has replaced the traditional cathode ray tube (CRT) in recent years. Since the flat display weighs less and emits less radiation, it has become a very important electronic product.  
           [0005]    As the advantages mentioned above, the flat display can be carried and used in many different places. In order to expand the utility of the flat display in variable environments, a flexible base stand is necessary.  
           [0006]    The traditional base stand for the flat display usually has a pedestal with a flat bottom to sustain the whole body. However, the flat display with traditional base can only be put on an even surface. Moreover, for providing a stable support, the traditional base stand is usually heavy and not portable.  
         SUMMARY OF THE INVENTION  
         [0007]    An object of the present invention is to provide a flat display with replaceable stand. The flat display comprises a first stand, a second stand detachably connected to the first stand, and a main body selectively supported by the second stand while the first stand is connected to the second stand or merely by the main body, wherein the first stand is hinged on the main body. Users can selectively position the flat display using the base stand or the simple stand in different environments.  
           [0008]    Particularly, when placed for a long period of time or on an even surface, the flat display of the present invention can use the base stand for a stable support. Additionally, the flat display of the present invention also can be placed using the simple stand if it needs frequent moving or placement on an uneven surface. Furthermore, a handle is disposed on the flat display so that users can carry and move the flat display more easily.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0018]    As shown in FIG. 1, the flat display of the present invention comprises a main body  1  connected with a handle  21  so that users can lift the flat display easily.  
         [0019]    In FIG. 2, moreover, the flat display comprises a carrying portion  2  with the handle  21  and a plurality of screw holes  22  therein. The carrying portion  2  and the main body  1  are joined by the screws (not shown) in the screw holes  22 . The simple stand  4  is connected to the carrying portion  2  with a hinge  3 . Furthermore, the simple stand  4  can rotate within a specified range of angle along the hinge  3  with the simple stand  4  and the main body  1  at a small angle (as shown in FIG. 7) or at a large angle (as shown in FIG. 8).  
         [0020]    Additionally, instead of connecting to the carrying portion  2 , the simple stand  4  can also connect to the main body  1  by a hinge directly.  
         [0021]    In FIG. 3, the flat display is supported by the base stand  5  connected to the simple stand  4 . The base stand  5  is hollow to house the simple stand  4  when the simple stand  4  and the base stand  5  are connected. Moreover, The base stand  5  comprises a pedestal  51  with a flat bottom surface so that the base stand  5  can provide a stable support.  
         [0022]    In FIG. 4 and FIG. 5, a pair of parallel guide rails  52  and an engaging portion  53  are disposed inside the base stand  5 . When connecting the simple stand  4  and the base stand  5 , the simple stand  4  is inserted along the guide rails  52  until contacting a spring  54  disposed in the bottom of the groove  52 . With continuing pushing of the simple stand  4  downward, the reverse spring force against the simple stand  4  increases, and the simple stand  4  and the base stand  5  are tightly combined while the engaging portion  53  joins into the hole  41  of the simple stand  4 .  
         [0023]    Since the engaging portion  53  has a spring (not shown) inside, when the hole  41  moves to the position of the engaging portion  53 , the engaging portion  53  spontaneously joins into the hole  41  by spring force. Thus, the simple stand  4  and the base stand  5  are connected.  
         [0024]    Furthermore, users can separate the base stand  5  from the simple stand  4  by pushing a button  56 . In FIG. 4, the button  56  is disposed in the back of the base stand  5 . A protrusion  561  connected to the button  56  passes through a hole  551  of a cover  55  and contacts with the engaging portion  53 . When pushing the button  56 , the spring inside the engaging portion  53  is compressed, and the engaging portion  53  is separated from the hole  41 . Thus, users can easily pull the handle  21  up so that the base stand  5  is separated from the simple stand  4 .  
         [0025]    Before connecting the base stand  5  and the simple stand  4 , as shown in FIG. 5, the simple stand  4  has to be inserted into the hollow base stand  5  from top to bottom. In FIG. 6, after inserting the simple stand  4 , the hole  41  and the engaging portion  53  are joined so that the simple stand  4  is housed and connected inside the base stand  5 .  
         [0026]    The present invention provides a flat display with a replaceable base stand to easily combine and separate the base stand  5  and the simple stand  4 . The advantage of the present invention is that users can selectively position the flat display using the base stand  5  or the simple stand  4  in different environments.  
         [0027]    While the invention has been described by way of example and in terms of the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
