BACKGROUND 
     1. Technical Field 
     The present disclosure relates to display devices and, particularly, to a display device with a front-facing concealable interfaces. 
     2. Description of Related Art 
     Conventionally, a display device includes a casing defining a plurality of interfaces in a rear of the casing for connecting a plurality of connectors. However, the rear of the casing may be mounted to a wall, so it is inconvenient to plug or unplug the connectors.

     DETAILED DESCRIPTION 
     The present disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.” 
       FIGS. 1 and 2  show an embodiment of a display device  100 . The display device  100  includes a casing  20 , a display unit  40  mounted to the casing  20 , a connector assembly  60 , and a cover  80 . 
     A bottom of a front surface of the casing  20  defines a cutout  22 . The casing  20  defines two opposing pivot holes  24  in two end walls  23  bounding the cutout  22 , and two opposing rotation holes  26  in front portions of top sides of the end walls  23 . One of the end walls  23  defines a first positioning hole  271  and a second positioning hole  274  on either side of the pivot hole  24 . 
     The connector assembly  60  includes a rectangular rotating shell  62 , a plurality of interfaces  64 , and a plurality of cables  65 . The rotating shell  62  includes a front plate  622 , a rear plate  624  opposite to the front plate  622 , and two opposite end plates  625  connected between ends of the front plate  622  and the rear plate  624 . Two opposing connecting rings  66  perpendicularly extend out from the end plates  625 . A resilient nub  67  protrudes out from a front corner of one of the end plates  625 . The nub  67  is hemispherical. The interfaces  64  are defined in the front plate  622  of the rotating shell  62 , and arrayed lengthwise along the front plate  622 . The cables  65  extend through the connecting rings  66 , to be electrically connected to the interfaces  64 . 
     The cover  80  includes a protecting plate  82  and two opposing shafts  84  extending out from two ends of a top side of the protecting plate  82 . 
       FIG. 3  shows that, in assembly, the connector assembly  60  is received in the cutout  22  of the casing  20 , with the nub  67  aligning with the end wall  23  in which the first and the second positioning holes  271  and  274  of the casing  20  are defined. The cables  65  extend through the pivot holes  24  of the casing  20  to be connected to electronic elements in the casing  20 , and the connecting rings  66  are rotatably received into the pivot holes  24 . Thereby, the connector assembly  60  is rotataby received in the cutout  22 . When the nub  67  latches in the first positioning hole  271 , the interfaces  64  are oriented to be at the front surface of the casing  20  and facing outwards; when the nub  67  latches in the second positioning hole  274 , the interfaces  64  are oriented so as to be retracted in the casing  20  and facing the wall. The cover  80  is received in the cutout  22 , and the shafts  84  of the cover  80  are rotatably inserted into the rotation holes  26 . Thereby, the cover  80  is rotatably received in the cutout  22 , and the cover  80  covers the connector assembly  60  to be coplanar with the front surface of the casing  20 . 
       FIGS. 4 and 5  show that, in use, the display device  100  is installed on a wall (not shown). The cover  80  is rotated away from the connector assembly  60 , the connector assembly  60  is rotated forward, and the connecting rings  66  rotate in the pivot holes  24 . The nub  67  abuts against the end wall  23 , deforming the nub  67 , until the nub  67  aligns and latches with the first positioning hole  271 . Thereby, the interfaces  64  are located at the front surface of the casing  20 , as shown in  FIG. 4 , so it is convenient to plug or unplug connectors to or from the interfaces  64  of the casing  20 . Then the connector assembly  60  can be rotated rearward, to deform the nub  67 , until the nub  67  is disengaged from the first positioning hole  271 . The nub  67  slides against the end wall  23 , until the nub  67  aligns and latches with the second position hole  274 . Thereby, the connectors (not shown) plugged into the interfaces  64  are located at the rear surface of the casing  20 , as shown in  FIG. 5 . The cover  80  is restored to cover the connector assembly  60 . 
     While the disclosure describes examples and embodiments, it is to be understood that the disclosure is not limited thereto. On the contrary, the disclosure is intended to cover such 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.
