Referring to
The first drainage hole 126 may be formed by cutting a portion of the first waterproof rib 122, and the second drainage hole 127 may be formed by cutting a portion of the second waterproof rib 123. Alternatively, the first drainage hole 126 may be formed by penetrating a portion of the first waterproof rib 122, and similarly, the second drainage hole 127 may be formed by penetrating a portion of the second waterproof rib 123. The first drainage holes 126 may be formed in a plurality in the first waterproof rib 122. The second drainage holes 127 may be formed in a plurality in the second waterproof rib 123.
Referring to
The reinforcing member 140 may increase the rigidity of the display module 100 by being coupled to the rear surface of the holder 120. The reinforcing member 140 may prevent the display module 100 from bending.
The reinforcing member 140 may be formed of a material that is attracted by the magnetic force of the magnet 10 (see
The display module 100 may include a fastener 20. The fastener 20 may be provided on the upper and lower sides of the rear surface of the display module 100. According to an embodiment, the fastener 20 may be arranged at the upper center and the lower center of the rear surface of the display module 100, respectively, but there is no limit to such locations.
The fastener 20 may prevent the display module 100 from being separated from the cabinet 200. The display module 100 may be coupled to the cabinet 200 by the magnetic attraction between the plurality of magnets 10 and the reinforcing member 140. However, in response to a force greater than the magnetic attraction being applied to cause the display module 100 to separate from the cabinet 200, the display module 100 may be separated from the cabinet 200. To prevent such a situation, the fastener 20 may be configured to prevent the display module 100 from moving forwardly of the cabinet 200.
The display module 100 may include the first waterproof rib 122, the second waterproof rib 123, and a third waterproof rib 124, which protrude rearwardly from the rear surface of the holder 120. A sealing groove 125 (see
The waterproof groove 128 may be configured to allow water entering from the outside to flow so as not to pass through the sealing member 150. Because the waterproof groove 128 is formed to be much larger than a gap between the circuit case 300 and the first waterproof rib 122, the water flows down the waterproof groove 128 by gravity rather than moving along the circuit case 300 by capillary action. The waterproof groove 128 may be formed deeper than the sealing groove 125 to prevent the inflowing water from entering the sealing groove 125. At high flow rates, if the waterproof groove 128 is formed shallowly, the amount of water entering the sealing groove 125 may increase.
The number of waterproof ribs 122, 123 and 124 may be increased. The more waterproof ribs 122, 123 and 124, the less water may reach the sealing groove 125. In response to the waterproof ribs 122, 123 and 124 being formed in greater numbers, the drainage holes 126 and 127 formed at the lower portion of each waterproof rib may also be formed in greater numbers. The waterproof grooves 128 formed between the waterproof ribs 122, 123 and 124 may also be formed in greater numbers in response to the waterproof ribs 122, 123 and 124 being formed in greater numbers. The greater the number of waterproof grooves 128, the greater the amount of water that moves downward by gravity along the waterproof grooves 128 without reaching the sealing groove 125 that receives the sealing member 150. The waterproof grooves 128 may be formed to be deeper as they are formed further outwardly. In other words, the waterproof grooves 128 may be formed to be deeper than the sealing groove 125. The deeper the waterproof grooves 128, the more the number of sealing grooves and waterproof grooves may be formed, although only one sealing groove and one waterproof groove are shown herein, but they are not limited thereto.
The first waterproof rib 122, the second waterproof rib 123, and the third waterproof rib 124 may each be provided in a ring shape. The first waterproof rib 122, the second waterproof rib 123, and the third waterproof rib 124 may each be configured to surround the first connector 112 connecting the display module 100 and the circuit case 300. The first waterproof rib 122, the second waterproof rib 123, and the third waterproof rib 124 may each be formed to be spaced outwardly around the first connector 112. The second waterproof rib 123 may be arranged on the inner side of the first waterproof rib 122, and the third waterproof rib 124 may be arranged on the inner side of the second waterproof rib 123.
The first to third waterproof ribs 122, 123 and 124 may contact the front side of the circuit case 300 to prevent moisture from entering the inner side of the first to third waterproof ribs 122, 123 and 124 from the outer side of the first to third waterproof ribs 122, 123 and 124. The waterproof ribs 122, 123 and 124 may be formed in greater numbers. The greater the number of waterproof ribs 122, 123 and 124, the less the amount of water reaching the sealing groove 125 in which the sealing member 150 is received.
The sealing member 150 may be provided in the sealing groove 125 formed between the second waterproof rib 123 and the third waterproof rib 124. The sealing member 150 may be arranged to surround the first connector 112. The sealing member 150 may be formed to correspond to the shape of the sealing groove 125. The sealing member 150 may be provided in an approximately ring shape. The sealing member 150 may be made of a material capable of changing volume, and may be configured to include, for example, rubber.
According to an embodiment, the sealing member 150 may be attached to the rear surface of the display module 100, but is not limited thereto. The sealing member 150 may also be attached to the front surface of the circuit case 300 so as to correspond to the sealing groove 125.
The display module 100 may include a first waterproof rib 122a, a second waterproof rib 123a, a third waterproof rib 124a, and a sealing groove 125a arranged symmetrically from side to side with the first waterproof rib 122, the second waterproof rib 123, the third waterproof rib 124, and the sealing groove 125. For ease of description, the first to third waterproof ribs 122a, 123a and 124a may be referred to as left waterproof ribs, and the first to third waterproof ribs 122, 123 and 124 may be referred to as right waterproof ribs.
The left waterproof ribs 122a, 123a and 124a and the right waterproof ribs 122, 123 and 124 may be provided in the same symmetrical configurations from side to side. This is to allow the display module 100 to be coupled to at least one of the left or right column of the two columns of the cabinet 200. For example, in response to the display module 100 being coupled to the right column of the cabinet 200, the first connector 112 may be arranged on the inner side of the right waterproof rib 122, 123 and 124, and the sealing member 150 may be provided in the right sealing groove 125 to prevent water from entering the first connector 112.
Conversely, in response to the display module 100 being coupled to the left column of the cabinet 200, the first connector 112 may be arranged on the inner side of the left rib 122a, 123a and 124a, and the sealing member 150 may be provided in the left sealing groove 125a. In addition, no opening may be provided on the inner side of the waterproof rib in which the first connector 112 is not arranged.
The display module 100 may further include guide ribs 161, 162 and 163 configured to guide a flow of water for dispersion. The guide ribs 161, 162 and 163 may include a first guide rib 161, a second guide rib 162, and a third guide rib 163. The guide ribs 161, 162 and 163 may each be formed in a plurality, and may each be formed at a predetermined interval. The guide ribs 161, 162 and 163 may be formed entirely on the rear surface of the display module 100 for structural stability of the display module 100. The guide ribs 161, 162 and 163 may also be formed on a lower side of the waterproof ribs 122, 123 and 124 to disperse the draining water.
Referring to
Below, for ease of description, the right waterproof ribs 122, 123 and 124 and the right sealing groove 125 will be referred to as the waterproof ribs 122, 123 and 124 and sealing groove 125.
Referring to
In response to the display module 100 being coupled to the cabinet 200, the sealing member 150 may be in contact with the front surface of the first case 310. The sealing member 150 may seal between the front surface of the first case 310 and the rear surface of the holder 120 by contacting the front surface of the first case 310 and the rear surface of the holder 120. In response to the display module 100 being coupled to the cabinet 200, the sealing member 150 may prevent water from entering from the outer side of the sealing member 150 to the inner side of the sealing member 150. As such, the sealing member 150 may be configured to seal between the display module 100 and the circuit case 300 when the display module 100 and the circuit case 300 are coupled.
The display apparatus 1 may include the first waterproof rib 122, the second waterproof rib 123, the third waterproof rib 124, the sealing member 150, and a rib 311 for blocking water ingress into the interior of the display module 100 where the first connector 112 is located and into the interior of the circuit case 300 where the second connector 301 is located.
The display module 100 may block water ingress into the interior of the display module 100 by blocking water from entering through the opening formed on the inner side of the third waterproof rib 124. In other words, the display module 100 may be arranged to block water ingress except for an opening that allows the first connector 112 to be exposed to the outside. The circuit case 300 may block water ingress into the interior of the circuit case 300 by blocking water from entering through a case opening 311a. In other words, the circuit case 300 may be configured to block moisture from entering except for the case opening 311a that allows the second connector 301 to be exposed to the outside. Accordingly, by sealing the opening inside the third waterproof rib 124 of the display module 100 and the case opening 311a of the circuit case 300, water ingress into the display apparatus 1 may be blocked.
In order for water to enter the interior of the display apparatus 1 where the first connector 112 and the second connector 301 are located, as indicated by the arrows in
The waterproof ribs 122, 123 and 124 may be formed at the same height as the sealing member 150 so as to be in contact with the circuit case 300 when the display module 100 and the circuit case 300 are coupled. The waterproof ribs 122, 123 and 124 may be formed to be in contact with the circuit case 300, so that the amount of water entering a waterproof area may be reduced, which may improve the waterproof performance.
The guide ribs 161, 162 and 163 may be formed at the same height as the sealing member 150 so as to be in contact with the circuit case 300 when the display module 100 and the circuit case 300 are coupled. The guide ribs 161, 162 and 163 may be formed to be in contact with the circuit case 300, so that the amount of water entering the waterproof area may be reduced, which may improve the waterproof performance.
In addition, the display apparatus 1 may prevent water from entering the interiors of the display module 100 and the circuit case 300 by sealing only a portion of the rear surface of the display module 100 and a portion of the front surface of the circuit case 300.
As described above, the display module 100 may be configured to be waterproof by blocking water from entering the opening formed on the inner side of the third waterproof rib 124. The circuit case 300 may be configured to be waterproof by blocking water from entering the case opening 311a. Accordingly, the display apparatus 1 may be made waterproof by sealing only a partial area of the rear surface of the display module 100 and a partial area of the front surface of the circuit case 300 corresponding thereto. The partial area may refer to an area on the inner side of the sealing member 150. The first to third waterproof ribs 122, 123 and 124, the sealing member 150, and the rib 311 may block water from entering the inner side of the sealing member 150, and the area on the inner side of the sealing member 150 may be relatively small in area, thereby effectively blocking moisture from entering. In other words, by reducing the area that needs to be waterproofed, the waterproofing performance may be improved. Furthermore, by reducing the area that needs to be waterproofed, the risk of water ingress into the area that needs to be waterproofed may be reduced.
Referring to
The second drainage hole 127 may be positioned at the lower portion of the second waterproof rib 123 to drain water because if the water existing in the sealing groove 125 is not drained, additional water inflow may increase the possibility of water ingress into the interior of the sealing member 150. The first drainage hole 126 may be positioned at the lower portion of the first waterproof rib 122 to drain water because if water existing in the waterproof groove 128 is not drained, additional water inflow may increase the possibility of water ingress into the interiors of the sealing groove 125 and the sealing member 150.
The first drainage hole 126 and the second drainage hole 127 may be arranged to be spaced apart in the vertical direction and the left-and-right direction so as not to overlap in the vertical direction. In other words, the first drainage hole 126 may not be aligned with the second drainage hole 127 in the vertical direction.
Such a structure is designed to prevent moisture from entering the first connector 112 through the first drainage hole 126 and the second drainage hole 127. In a case where the first drainage hole 126 and the second drainage hole 127 are positioned to overlap each other in the vertical direction, the water inflow path from below the first drainage hole 126 through the first drainage hole 126 and the second drainage hole 127 to the sealing groove 125 may be simplified, which may increase the possibility of water entering the sealing groove 125. In a case where the first drainage hole 126 and the second drainage hole 127 are positioned to be spaced apart from each other in the left-and-right direction, water entering through the first drainage hole 126 may first move laterally and then upwardly before passing through the second drainage hole 127. Accordingly, the water inflow path through the first drainage hole 126 and the second drainage hole 127 to the sealing groove 125 may be complicated, which may reduce the possibility of water entering the sealing groove 125. Although the sealing member 150 is arranged to block moisture from entering the interiors of the sealing groove 125 and the third waterproof rib 124, it is desirable to reduce the amount of moisture entering the sealing member 150 in order to improve the waterproof performance of the display module 100.
In addition, such a structure is designed to prevent the water discharged from the second drainage hole 127 from directly draining into the first drainage hole 126. In a case where the water discharged from the second drainage hole 127 is directly drained into the first drainage hole 126, the downward flow rate may increase, which may reduce the function of the guide ribs 161, 162 and 163, and the flow rate to the display module 100 located below may not be reduced. Accordingly, the first drainage hole 126 and the second drainage hole 127 may be arranged to be spaced apart in the left-and-right direction and in the up-and-down direction.
Below, for ease of description, the right waterproof ribs 122, 123 and 124 and the right sealing groove 125 will be referred to as the waterproof ribs 122, 123 and 124 and the sealing groove 125.
Referring to
The guide ribs 161, 162 and 163 may include the first guide rib 161 that guides water to move in the left-and-right direction. The first guide ribs 161 may be formed to be spaced apart from each other. The first guide rib 161 may guide water flowing in the display module 100 in the left-and-right direction, thereby reducing the flow rate in the up-and-down direction and distributing the water left-and-right. The first guide rib 161 may be formed at a predetermined distance from the drainage holes 126 and 127 in the up-and-down direction so that water flowing out of the drainage hole 126 and 127 is guided in the left-and-right direction.
The guide ribs 161, 162 and 163 may include the second guide rib 162 that guides the water to move in the up-and-down direction. The second guide rib 162 may be formed perpendicular to the first guide rib 161. The second guide ribs 162 may be formed to be spaced apart from each other. The second guide ribs 162 may prevent the water flowing in the display module 100 from flowing excessively in the left-and-right direction and may guide the water in the up-and-down direction to allow the water to be drained smoothly by gravity.
The guide ribs 161, 162 and 163 may include the third guide rib 163 extending along an inclined direction from the first guide rib 161 and the second guide rib 162. The third guide rib 163 may be formed along a portion where the first guide rib 161 and the second guide rib 162 intersect. The third guide rib 163 may distribute water so that water flowing in the display module 100 is not concentrated in a particular portion. The third guide rib 163 may be positioned below the drainage holes 126 and 127 to disperse water flowing out of the drainage holes 126 and 127.
Water drained from the drainage holes 126 and 127 may be dispersed downward along the guide ribs 161, 162 and 163. By dispersing the water, the amount of water flowing to the display module 100 positioned below may be reduced, so that the waterproof performance of the display module 100 positioned below may be further improved.
Referring to
Referring to
In the waterproof area of the display module 100, water may flow along the waterproof groove 128 and the sealing groove 125 and drain through the drainage holes 126 and 127 as shown in
Referring to
Since the water flowing from the display module 100 positioned above is dispersed and introduced into the display module 100 positioned below, the absolute amount of flow reaching the waterproof area, i.e., the area where the waterproof ribs 122, 123 and 124 and the sealing member 150 are arranged, may be reduced.
By arranging the plurality of cabinets 200 in which the plurality of display modules 100 are coupled adjacent to each other in the left-and-right direction X and the up-and-down direction Y, the flow rate may be dispersed rather than concentrated even when the large size display apparatus 1 is formed. As a result, the amount of water reaching the display module 100 positioned below may be small.
Although certain exemplary embodiments are illustrated and described above, the present disclosure is not limited to the certain embodiments, various applications may of course be performed by those skilled in the art without deviating from what is claimed in the scope of claims, and such applications should not be understood separately from the technical idea or prospects herein.
