     BACKGROUND 
     1. Field 
     Exemplary embodiments of the inventive concept relate to a display apparatus including a glass plate. 
     2. Description of the Related Art 
     In general, a “display apparatus” is a comprehensive term which generally refers to a variety of devices which visually display data on a display using text or figures. 
     Particularly, the application of liquid crystal display (LCD) devices, as a flat panel display device, is expanding to computer monitors and TVs, and there is increasing demand for such LCD devices. 
     Display apparatuses are classified into various types according to plural methods of displaying signal-processed image information on a screen. Recently, liquid crystal displays (LCDs) and plasma display panels (PDPs) have become widely used. 
     A display apparatus includes a display panel which displays an image, a glass plate mounted on the front surface of the display panel, a front disposed at an edge portion of the glass plate and the display panel to constitute a bezel and functioning as a frame which supports the glass plate and the display panel, and a casing which supports the back of the display and constituting an external body. 
     However, since the glass plate is attached to the display panel in such display apparatuses, disassembly of the entire display apparatus is required for repair or replacement of the glass plate. Thus, after-sales service (A/S) time therefore increases. 
     In addition, since the glass plate is provided at an inner portion of the bezel, the thickness of the bezel increases.

     DETAILED DESCRIPTION 
     Reference will now be made in detail to the exemplary embodiments of the inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. 
       FIG. 1  is a perspective view which schematically illustrates the front of a display apparatus  1  according to an exemplary embodiment of the inventive concept.  FIG. 2  is a perspective view which schematically illustrates a glass and a display of the display apparatus. 
     As shown in  FIGS. 1 to 3 , the display apparatus  1  includes a display  10  displaying image information and a glass  20  which is detachably mounted on the front surface of the display  10  to protect the display  10 . 
     Generally, the display  10  includes a display panel (not shown) which displays image information, a bezel (not shown) disposed at an outer peripheral portion of a frame of the display panel, and a back case  11  which is connected to the rear surface of the display panel in order to support the display panel. 
     The glass  20  includes a glass plate  21  and a frame  22  surrounding peripheral portions of the glass plate  21 . The frame  22  includes a holder  30  which couples the glass to the display  10 . 
     The frame  22  of the glass  20  may include a plurality of holders  30  such that each of the four sides of the frame  22  includes at least one holder  30 . 
     In addition, the back case  11  of the display  10  has a first coupling portion  12  to which the holder  30  is coupled. 
     A first coupling portion  12  may be formed to correspond to the position and number of the holder  30 . 
       FIG. 4  schematically illustrates the holder  30  provided at the glass  20 .  FIG. 5  schematically illustrates the glass  20  mounted on the display  10  by the holder unit.  FIG. 6  schematically illustrates operation of the holder  30 . 
     As shown in  FIG. 4 , the frame  22  of the glass  20  has a holder installation portion  23 , to which the holder  30  is coupled. 
     In addition, the holder  30  includes a hinge  31  which is rotatably installed at the glass  20  and a fixing device  33  extending from the hinge  31  which fixes the glass  20  to the display  10 . 
     The holder  30  has an “L” shape, and the fixing device  33  is bent from the hinge  31 . 
     The hinge  31  includes hinge protrusions  32  at both ends thereof. 
     The holder installation portion  23  of the glass  20  has guide grooves  24  formed outward from the inside of the frame  22  to which the hinge protrusions  32  of the hinge  31  are coupled and hinge grooves  25  extending from the guide grooves  24  in the horizontal direction of the frame  22 . 
     In this regard, the guide grooves  24  may have a diameter greater than that of the hinge protrusions  32  such that the guide grooves  24  guide the movement and rotation of the hinge protrusions  32  during installation of the holder  30 , and the hinge grooves  25  may have the same diameter as that of the hinge protrusions  32  in order to fix the holder  30  to the frame  22 . 
     Thus, the holder  30  is assembled into the upper side of the frame  22  by assembling the hinge protrusions  32  of the hinge  31  into the guide grooves  24  of the holder installation portion  23  formed at the upper side of the frame  22  of the glass  20 , for example, by moving the hinge protrusions  32  upward from the lower portions of the guide grooves  24  formed at the upper side of the frame  22  of the glass  20  and installing the hinge protrusions  32  into the hinge grooves  25  extending from the guide grooves  24  in the horizontal direction as shown in  FIG. 4 . By rotating the hinge protrusions  32  installed at the hinge grooves  25 , the glass  20  may be coupled with the display  10 . 
     In addition, the holder  30  is assembled into a left or right side of the frame  22  by moving the hinge protrusions  32  to the guide grooves  24  formed at the left or right side of the frame  22  and installing the hinge protrusions  32  into the hinge grooves  25  which extend from the guide grooves  24 . By rotating the hinge protrusions  32  installed at the hinge grooves  25  in the transverse direction, the glass  20  may be coupled with the display  10 . 
     A second coupling portion  34  is formed at one end of the fixing device  33  of the holder  30 . The second coupling portion  34  may be a cylindrical protrusion. 
     In addition, the second coupling portion  34  is coupled with the first coupling portion  12  disposed at the back case  11  to correspond with the second coupling portion  34  of the holder  30 . 
     In this regard, the first coupling portion  12  may be a cylindrical recess such that the cylindrical protrusion of the second coupling portion  34  is contained in the first coupling portion  12 . 
     Here, the first coupling portion  12  has the recess and the second coupling portion  34  has the protrusion. However, the first coupling portion  12  and the second coupling portion  34  may be coupled with each other in various ways, in addition to using the cylindrical protrusion and recess shown in the exemplary embodiment. 
     As shown in  FIG. 6 , when the holder  30  hinge-fixed to the holder unit installation portion  23  of the glass  20  is rotated downward, the second coupling portion  34  provided at the fixing device  33  of the holder  30  is coupled with the first coupling portion  12  provided at the back case  11  of the display  10 . 
     Referring to  FIGS. 7 and 8 , an example of opening and closing operations of the holder  30  will be described in detail. 
     For assembly of the glass  20  and the display  10 , which are separately formed, the glass  20  and the display  10  are disposed at predetermined positions. 
     In this regard, the holder  30  installed in the holder installation portion  23  of the frame  22  of the glass  20  may be disposed such that the fixing device  33  of the holder  30  is raised upward. Here, the hinge protrusions  32  of the hinge  31  are fixed to the hinge grooves  25 . 
     When the display  10  is disposed on the glass  20  to be assembled, the holder  30  is rotated downwardly from the raised position to couple the second coupling portion  34  of the fixing device  33  with the first coupling portion  12  provided at the back case  11  of the display panel  10 . 
     When a plurality of holder  30  provided at the frame  22  of the glass  20  is fixed to the back case  11 , the glass  20  and the display  10  are fixed to each other. 
     In addition, when the glass  20  is separated from the display  10 , the second coupling portion  34  of the fixing device  33  of the holder  30  is separated from the first coupling portion  12  of the back case  11  by rotating the holder  30  upward. 
     When all of the holders  30  of the frame  22  of the glass  20  are separated, the glass  20  is easily separated from the display  10 . 
     Since the glass  20  is detachably coupled with the display  10  as described above, A/S of the glass plate  21  for repair and replacement thereof may be facilitated. Accordingly, A/S time may be reduced. 
     Referring to  FIGS. 9 and 10 , a display apparatus  100  according to another exemplary embodiment of the inventive concept includes a housing  120  which constitutes the appearance of the display apparatus  100  and including a front opening  120   a  and a rear opening  120   b  respectively at the front and rear surfaces thereof, a glass  110 , disposed at the front opening  120   a  of the housing  120 , a back cover  140  implemented to constitute the back appearance of the housing  120 , and a display  160  disposed in the housing  120 . 
     The housing  120 , which has a rectangular shape having the front opening  120   a  and the rear opening  120   b , includes a first panel  121  which constitutes the upper surface, a third panel  123  which constitutes the lower surface to support the bottom, and a second panel  122  and a fourth panel  124  disposed both side surfaces connecting the first panel  121  and the third panel  123 . 
     The glass  110  disposed at the front opening  120   a  of the housing  120  may be formed of a transparent material with sufficient rigidity. According to the exemplary embodiment, the glass  110  may include a glass plate  111  or tempered glass having a size and shape which correspond to the front opening  120   a  of the housing  120 . 
     The display  160  which displays an image is disposed in the housing  120  behind the glass plate  111  such that the image displayed on the display  160  may be viewed from the outside. 
     Although not shown in the drawings, the display  160  may include a liquid crystal panel displaying an image, a backlight disposed behind the liquid crystal panel and emitting light to the liquid crystal panel, and a controller disposed behind the backlight, including a circuit board, and controlling operations of the liquid crystal panel and the backlight. 
     The back cover  140  includes an inlet  141  disposed at a lower portion thereof through which air is introduced and an outlet  145  disposed at an upper portion thereof through which the air introduced via the inlet  141  is discharged. 
     An air circulator  130  may further be disposed at a lower portion of the back cover  140  in order to cool the display  160 . 
     The display apparatus  100 , which may be installed outdoors, may be heated by sunlight transmitted through the glass  110  disposed at the front surface, and accordingly, the interior of the display apparatus  100  may become deteriorated. 
     Thus, the display apparatus  100  may include the air circulator  130  that keeps the temperature of the interior of the display apparatus  100  within a predetermined range by circulating air introduced from the outside into the housing  120 . 
     In addition, external water or dust may be introduced into the display apparatus  100  when installed outdoors. Thus, the display apparatus  100  according to the exemplary embodiment may include a waterproof device  150  to prevent external water or dust from being introduced thereinto. 
       FIG. 11  schematically illustrates the glass of  110  of the display apparatus  100  on which a waterproof device  150  is mounted.  FIG. 12  schematically illustrates the waterproof device  150  provided to the glass  110 .  FIG. 13  is a cross-sectional view schematically illustrating the display apparatus  100 .  FIG. 14  is an enlarged view illustrating portion “A” of  FIG. 12 .  FIG. 15  is an enlarged view illustrating portion “B” of  FIG. 12 . 
     As shown in  FIG. 11 , the waterproof devices  150  are disposed between the housing  120  and the glass  110  and between the housing  120  and the back cover  140 . 
     The waterproof device  150  includes a glass holder  151  fixed to the glass  110  and rubber  156  provided at the glass holder  151 . 
     The glass holder  151  includes a supporter  152  attached to a frame of the rear surface of the glass plate  11  of the glass  100 , a rubber attachment portion  153  disposed at a surface of the supporter  152  to which the rubber  156  is attached, and a coupling portion  154  to be coupled with the housing  120 . 
     In this regard, the rubber attachment portion  153  may be formed at an outer frame of the glass holder  151 . 
     In addition, the coupling portion  154  has a bolt B coupling hole  155  to be fixed to the housing  120 . 
     A waterproof bracket  157 , which contacts the rubber  156  of the waterproof device  150  to seal the interior of the display apparatus  100 , is formed at the housing  120 . 
     The waterproof bracket  157  has a bolt hole  157   a  which is to be coupled by a bolt B with the coupling portion  154  of the waterproof  150 . 
     Thus, the housing  120 , the waterproof device  150 , and the glass  110  are fixed by the bolt hole  157   a  of the waterproof bracket  157  of the housing  120  and the bolt B penetrating the coupling hole  155  of the coupling portion  154  of the glass holder  151 . 
     In addition, the interior of the housing  120  may be sealed by disposing the rubber  156  of the waterproof device  150  on the rear surface of the glass  110  in contact with the waterproof bracket  157  of the housing  120 . 
     In this regard, space between the glass  110  and the housing  120  is completely sealed by compressing the rubber  156  using the waterproof bracket  157 . 
     When the glass plate  111  of the glass  110  of the display apparatus  100  is repaired or replaced, the glass  110  may be separated by removing the bolt B that fixes the housing  120  and the glass  110 . Accordingly, A/S may be facilitated, and A/S time may be reduced. 
     In addition, the waterproof device  150  is disposed between the housing  120  and the back cover  140  as shown in  FIG. 15 . 
     In this regard, the waterproof device  150  includes rubber  156  disposed at the back cover  140  and a waterproof bracket  157  formed at the housing  120  to contact the rubber  156 . 
     The rubber  156  may be attached to an edge portion of an inner side wall of the back cover  140 . 
     In addition, the waterproof bracket  157  includes a first waterproof bracket  158  bent from the bottom of the first panel  121  of the housing  120  toward the back cover  140  to contact the rubber  156  and a second waterproof bracket  159  surrounding an outer portion of the first waterproof bracket  158 . 
     Thus, entry of water or dust into the housing  120  may be prevented by the waterproof  150  which is disposed between the housing  120  and the back cover  140 . As a result, product durability may be improved. 
     Referring to  FIG. 13 , operation of the display apparatus  100  will be briefly described. 
     In the display apparatus  100  installed outdoors, air introduced from the outside circulates through the housing  120  by the air circulator  130 , and thus the temperature inside the housing  120  may be kept within a predetermined range. 
     External air is introduced through the inlet  141  disposed at a lower portion of the rear surface of the back cover  140 , and heat-exchanged air after circulation through the housing  120  is discharged via the outlet  145  disposed at an upper portion of the rear surface of the back cover  140 . 
     In this regard, the inlet  141  includes a first filter  132 , and the outlet  145  includes a second filter  136 , such that impurities contained in the air introduced and discharged, are filtered. 
     The air circulator  130  includes a blower fan  133  which generates a suction force and a ventilation force while rotating and a driving motor  134  to drive the blower fan  133  by generating a rotating force. 
     Thus, air introduced via the inlet  141  circulates through the housing  120  and is discharged to the outside via the outlet  145  by the internal blower fan  133 . 
     The glass  110  is mounted on the front surface of the housing  120 , and the back cover  140  is mounted on the rear surface of the housing  120 . Since the waterproof units  150  are respectively disposed between the housing  120  and the glass  110  and between the housing  120  and the back cover  140  according to the exemplary embodiment, entry of external moisture or dust into the housing  120  may be prevented. 
     In addition, the housing  120  may be separated from the glass  110  and from the back cover  140  during, for example, A/S for repair and/or replacement of parts. Accordingly, A/S may be facilitated, and A/S time may be reduced. 
     As is apparent from the above description, A/S for repair and replacement of a glass plate may be facilitated since the glass plate is detachably mounted on a display, and thus A/S time may be reduced. 
     In addition, display apparatuses may be classified into two types, display apparatuses provided with a glass plate and display apparatuses not provided with a glass plate, and accordingly the display apparatus may be manufactured to provide a wide range of product groups. 
     In addition, since parts are dismantled from the display apparatus, A/S for repair and replacement of the parts may be facilitated, and A/S time may be reduced. 
     In addition, product durability may be improved by improving waterproof properties. 
     Although a few exemplary embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
