However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure. 
         [0014]      FIGS. 1-2  illustrate a support for a display in accordance with an embodiment. The support includes a mounting board  10 , a rack  20 , a rotation assembly  50 , and a slip assembly  70 . 
         [0015]    The mounting board  10  can be mounted on a display  90  (referring to  FIG. 3 ). The mounting board  10  includes a power connector  11 . The power connector  11  includes three power transmitting posts, being a first power transmitting post  111 , a second power transmitting post  112 , and a third power transmitting post  113 . The first power transmitting post  111  is located above the third power transmitting post  113 , and the second power transmitting post  112  is located below the third power transmitting post  113 . The three power transmitting posts,  111 ,  112 , and  113 , can be electrically connected to the display  90  to transmit power to the display  90  when the mounting board  10  is mounted on a display  90 . 
         [0016]    The rack  20  can be mounted on a wall. The rack  20  includes a frame  21  and a bottom plate  22  mounted on the frame  21 . The frame  21  includes two parallel long edges  211  and a short edge  212  connected between the two long edges  211 . The frame  21  defines an opening  213 . A cover  214  can be mounted on the frame  21  to close the opening  213 . A power port  215  is mounted on the short edge  212 . Two parallel and exposed rails  221  are mounted on the bottom plate  22 . In at least one embodiment, the two parallel rails  221  are a null line and a live line which are connected to the power port  215 . The two parallel bare rails  221  are parallel to the two long edges  211 . 
         [0017]    The slip assembly  70  includes a first slip block  71 , a second slip block  72 , a conduction block  73 , a gasket  74 , and a restricting piece  75 . 
         [0018]    The first slip block  71  defines a substantially square receiving hole  711 . Each of a top edge and a bottom edge surrounding the receiving hole  711  forms a slip post  712 . A distal end of the slip post  712  includes a restricting portion  713 . The first slip block  71  can slide between the pair of long edges  211  via the opening  213 . 
         [0019]    The second slip block  72  can be slidably mounted in the receiving hole  711 . Each of a top side and a bottom side of the second slip block  72  forms a sliding groove  721 . The second slip block  72  includes conduction pieces  722  which face to the first slip block  71 . The conduction pieces  722  includes a first conduction piece  723  and a second conduction piece  724 . The second slip block  72  includes a mounting block  725  which faces away from the first slip block  71 . The mounting block  725  is non-circular. The mounting block  725  defines an accommodation hole  726 . 
         [0020]    The conduction block  73  can be accommodated in the accommodation hole  726 . The conduction block  73  defines a first conduction groove  731 , a second conduction groove  732 , and a conduction hole  733 . The first conduction groove  731  and the second conduction groove  732  are arc shaped. The first conduction groove  731  is located above the conduction hole  733 , and the second conduction groove  732  is located below the conduction hole  733 . The exposed surfaces of the first conduction groove  731 , the second conduction groove  732 , and the conduction hole  733  are coated with electrically conductive materials. After the conduction block  73  is received in the accommodation hole  726  of the second slip block  72 , the first conduction piece  723  is in electrical contact with the first conduction groove  731 , the second conduction piece  724  is in electrical contact with the second conduction groove  732 , and the conduction hole  733  is connected to ground. 
         [0021]    The gasket  74  defines a mounting hole  741  to receive the mounting block  725 . The restricting piece  75  defines a through hole  751  to received the mounting block  725 . The restricting piece  75  comprises bars  752 . In one embodiment, the restricting piece  75  is made of high-friction material. 
         [0022]    The rotation assembly  50  includes a friction piece  51 , a securing piece  52 , and fixing piece  53 . The friction piece  51  and the securing piece  52  together define a rotation hole  511 . The mounting block  725  of the second slip block  72  can rotate in the rotation hole  511 . The fixing piece  53  can be mounted on the securing piece  52 . The fixing piece  53  defines an inserting hole  531  for receiving the power connector  11  of the mounting board  10 . 
         [0023]    Referring to  FIGS. 1-8 , in assembly, the conduction block  73  is mounted in the accommodating hole  726  of the second slip block  72 . The second slip block  72  is then mounted in the receiving hole  711  of the first slip block  71 , with the slip post  712  sliding in the sliding groove  721 . Then, the first slip block  71  slides in the rack  20  with the first conduction piece  723  and the second conduction piece  724  electrically connected to the two rails  221 . 
         [0024]    The mounting block  725  of the second slip block  72  is inserted in the mounting hole  741  and the through hole  751  to locate the gasket  74  and the restricting piece  75  on the mounting block  725 . The friction piece  51  is mounted on one side of the securing piece  52 , and the fixing piece  53  is mounted on another side of the securing piece  52 . The securing piece  52  is mounted on the mounting board  10 . The power connector  11  is inserted through the inserting hole  531 . 
         [0025]    The mounting block  725  is inserted in the rotation holes  511  of the friction piece  51  and the securing piece  52 . The friction piece  51  abuts the restricting piece  75 . At the same time, the first power transmitting post  111  is inserted in the first conduction groove  731  and electrically connected to the first conduction groove  731 . The second power transmitting post  112  is inserted in the second conduction groove  732  and electrically connected to the second conduction groove  732 , and the third power transmitting post  113  is inserted in the conduction hole  733  and electrically connected to the conduction hole  733 . 
         [0026]    To use the support, the rack is mounted on a wall, a power source is electrically connected to the power port  215 . Electricity can thus be transmitted to the display  90  via the power port  215 , the rails  221 , the conduction pieces  722 , the conduction block  73 , and the power connector  11 . 
         [0027]    When the display  90  needs to slide, the second slip block  72  slides to disengage the conduction pieces  721  from the rails  221 . Then, the first slip block  71  slides in the rack to slide the display  90  to a new position, and the second slip block  72  slides backwardly to re-engage the the conduction pieces  721  with the rails  221 . 
         [0028]    When the display  90  is rotated, the rotation assembly  50  and the mounting board  10  rotate together with the display  90 . A friction force is generated between the friction piece  51  and the restricting piece  75  to hold the display  90  in any position. Simultaneously, the first power transmitting post  111  slides in the first conduction groove  731  and is kept in electrical contact with the first conduction groove  731 , the second power transmitting post  112  slides in the second conduction groove  732  and is kept in electrical contact with the second conduction groove  732 , and the third power transmitting post  113  rotates in the conduction hole  733  and is kept in electrical contact with the conduction hole  733 . Therefore, electrical power supplied to the display  90  is maintained.
