BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to display units, and more particularly, to a display unit which can be conveniently assembled. 
         [0003]    2. Description of Related Art 
         [0004]    Display systems play an important role in people&#39;s daily lives, showing images and text for all kinds of purposes. A display system typically includes a display, a front enclosure and a back enclosure. The display is assembled between the front enclosure and the back enclosure. However, in most conventional display systems, the assembly of the display to the front enclosure and the back enclosure is achieved by using separate fasteners (such as screws or bolts, and has to be completed with the help of tools such as a screwdriver. Therefore, the display system cannot be quickly and conveniently assembled. 
         [0005]    What is needed, therefore, is a display unit which can overcome the limitations described above.

     DETAILED DESCRIPTION 
       [0011]    Referring to  FIGS. 1-2 , a display unit in accordance with an embodiment of the present disclosure is shown. The display unit includes an upper cover  20 , a lower cover  10 , and a display  30  sandwiched between the upper cover  20  and the lower cover  10 . 
         [0012]    The display  30  has a rectangular configuration. The display  30  may be an LCD (Liquid Crystal Display), an OLED (Organic Light Emitting Diode) display or another suitable display. 
         [0013]    The lower cover  10  includes a rectangular lower plate  12 , a flange  14  extending upwardly and slantwise from a side of the lower plate  12 , a first clip  16  protruding upwardly from a top face of the lower plate  12 , a bracket  18  connecting the lower plate  12  with the flange  14 , and a rib  17  extending upwardly from the flange  14 . The lower plate  12  has a size larger than that of the display  30 , so that the display  30  can be substantially received in the lower cover  10 . The flange  14  is inclined in a manner that an included angle between the flange  14  and the lower plate  12  is larger than 90 degrees and less than 180 degrees. Preferably, the included angle between the flange  14  and the lower plate  12  is about 120 degrees. The flange  14  has a width far less than a length thereof. The first clip  16  includes a first stem  162  perpendicular to the lower plate  12 , and a first hook  164  protruding horizontally from a top end of the first stem  162 . The first stem  162  is elastically deformable, and has a length larger than a thickness of the display  30 . The first stem  162  can press against a lateral face of the display  30  to position the display  30  on the lower plate  12 . The first hook  164  is oriented towards the display  30 . The first hook  164  can press a part of a top face of the display  30  near the lateral face thereof downwardly towards the lower plate  12  so as to fix the display  30  on the lower plate  12 . 
         [0014]    The rib  17  is perpendicular to the flange  14  and the lower plate  12 . The rib  17  has a trapezoidal configuration, with a top face thereof being coplanar with that of the flange  14 . A rectangular groove  170  is defined in the top face of the rib  17 . The bracket  18  is located neighboring the first clip  16 . The bracket  18  includes a connecting portion  184  extending upwardly from the top face of the lower plate  12 , and a locking portion  182  extending horizontally from the flange  14  and connected to the connecting portion  184 . The connecting portion  184  has a length less than that of the first stem  162 . The connecting portion  184  is perpendicular to the first stem  162  and the locking portion  182 , and parallel to the rib  17 . The locking portion  182  is parallel to the lower plate  12 . 
         [0015]    Also referring to  FIGS. 3-4 , the upper cover  20  includes an upper plate  22 , a second clip  24  extending downwardly from a bottom face of the upper plate  22 , a pair of fins  26  formed downwardly from the bottom face of the upper plate  22 , and a beam  28  protruding downwardly from the bottom face of the upper plate  22 . The upper plate  22  is a flat rectangle, with an end curved downwardly towards the flange  14  of the lower cover  10 . The curved end of the upper plate  22  contacts the flange  14  to form a chamber (not labeled) between the lower cover  10  and the upper cover  20 , the chamber receiving the display  30  therein. The second clip  24  includes a second stem  242  connected to the upper plate  22 , a second hook  244  protruding horizontally from a bottom end of the second stem  22 , and a pair of reinforcing tabs  246  connecting the second stem  242  to the upper plate  22 . The second stem  242  is perpendicular to the lower plate  12 , and parallel to the first stem  162 . The second hook  244  is oriented in a direction remote from the display  30  and opposite to that of the first hook  164 . The second hook  244  is buckled with a bottom face of the locking portion  182  of the bracket  18 , to fix the upper cover  20  to the lower cover  10  (shown in  FIG. 4 ). The reinforcing tabs  246  are formed on the second stem  242  opposite to the second hook  242 . Each reinforcing tab  246  has a triangular configuration to increase strength of the second clip  24 . The pair of fins  26  are located adjacent to the second clip  24  and parallel to the reinforcing tabs  246 . Each fin  26  has a trapezoid shape with an inclined surface. 
         [0016]    The inclined surfaces of the fins  26  only contact the first hook  164  at an edge of the first hook  164 , to produce an inclined pressure applied to the first hook  164 . The inclined pressure can be divided into two component forces operating along two perpendicular directions. One of the component forces is oriented horizontally to press the first clip  16  against the display  30  in a horizontal direction towards a middle of the display  30 . The other component force is oriented vertically to press the first clip  16  against the display  30  downwardly towards the lower plate  12 . Thus, the fin  26  urges the first clip  16 , which elastically deforms to press against the display  30 . The beam  28  extends along the curved end of the upper plate  22  from one side of the upper cover  20  to an opposite side of the upper cover  20 . The beam  28  is fittingly retained into the groove  170  of the rib  17  of the lower cover  10  to position the upper cover  20  relative to the lower cover  10 . 
         [0017]    The first clip  16  formed on the lower cover  10  can conveniently fix the display  30  on the lower cover  10  without the need for separate fasteners (such as screws or bolts) and without the need for tools, whereby rapid assembly of the display unit can be achieved. Furthermore, the first clip  16  does not occupy too much space between the lower cover  10  and the upper cover  20 ; therefore, the display unit can be made thin enough to meet critical space requirements. 
         [0018]    It is believed that the present disclosure and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the present disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments.
