According to an embodiment, any one of the at least two first position adjusting members 131 may be disposed adjacent to an upper left end of the back surface of the display panel 120, and the other may be disposed adjacent to an upper right end of the back surface of the display panel 120.
Referring to
Here, the second bracket 132-1 may be fixed to the display panel 120, and specifically, disposed adjacent to the side end of the back surface of the display panel 120.
The second fixing member 132-2 according to an embodiment may be disposed adjacent to the side end of the front surface of the frame 110, and include a hole through which a part of the second bracket 132-1 is inserted. For example, the second fixing member 132-2 may include a space (e.g., hole) capable of receiving a protrusion part of the second bracket 132-1.
According to an embodiment, the second position adjusting member 132 may include the second adjustment bolt 132-3, and the second adjustment bolt 132-3 may be fastened to the second fixing member 132-2 after a part (e.g., protrusion part) of the second bracket 132-1 is inserted in the second fixing member 132-2.
Here, the second adjustment bolt 132-3 may be configured to directly contact one surface of the second bracket 132-1 through a through hole 132-4 of the second fixing member 132-2. The one surface of the second bracket 132-1 may be a surface to be pressed which receives pressure by the second adjustment bolt 132-3.
According to an embodiment, the second adjustment bolt 132-3 may rotate in the clockwise direction or the anti-clockwise direction, and the display panel 120 may move to the left side based on pressure applied to the one surface of the second bracket 132-1 increasing due to the second adjustment bolt 132-3 rotating in the clockwise direction.
In another example, based on the pressure applied to the one surface of the second bracket 132-1 decreasing due to the second adjustment bolt 132-3 rotating in the anti-clockwise direction, the display panel 120 may stop or move to the right side. The second adjustment bolt 132-3 may be implemented as a threaded member, and for example, may be implemented as a non-head bolt.
The above-described example is based on assuming that the second position adjusting member 132 is disposed adjacent to the right side end of the display apparatus 100, and a left side movement or a right side movement of the display panel 120 according to a clockwise or an anti-clockwise rotation of the second adjustment bolt 132-3 when the second position adjusting member 132 is disposed adjacent to the left side end of the display apparatus 100 may be different from the above-described example.
According to an embodiment, a state in which the second adjustment bolt 132-3 is fastened to the second fixing member 132-2, and configured to directly contact the one surface of the second bracket 132-1 through the through hole 132-4 of the second fixing member 132-2 will be described with reference to
Referring to
The second bracket 132-1 may not include a fastening hole (a hole corresponding to the fastening hole 131-5 of the first bracket 131-1) to the protrusion part unlike the first bracket 131-1.
According to an embodiment, by adjusting the pressure on the one surface of the second bracket 132-1 of the second adjustment bolt 132-3 by rotating the second adjustment bolt 132-3 in the clockwise direction or the anti-clockwise direction, the plurality of first coupling members disposed at the front surface of the frame 110 and the plurality of second coupling members disposed at the rear surface (or, back surface) of the display panel 120 may adjust a position of a second direction with respect to the frame 110 of the display panel 120 which is attached and supported by attractive force.
For example, by increasing or decreasing the pressure on the one surface of the second bracket 132-1 by rotating the second adjustment bolt 132-3 in the clockwise direction or the anti-clockwise direction, the display panel 120 may be moved minutely to the left side or the right side with respect to the frame 110.
Referring to
As described above, the display apparatus 100 may be fixed to a wall by a wall mounted unit, or installed indoors or outdoors in a method which is supported by a stand. In this case, the portion of the plurality of display panels forming the display apparatus 100 may be level with the bottom, the remaining display panels may not be level with the bottom even though the gradient is 0 (e.g., a state which is not tilted), or the gradient may not be 0.
Based on the gradient degree of the respective display panels being different, an interval may occur in between the plurality of display panels as illustrated in
Accordingly, according to an embodiment, the interval in between the plurality of display panels may be minimized by appropriately rotating the second adjustment bolt 132-3 provided in the respective second position adjusting members 132 provided in the display apparatus 100 in the clockwise direction or the anti-clockwise direction.
For example, when the second adjustment bolt 132-3 is rotated in the clockwise direction by one revolution, the pressure applied to the one surface of the protrusion part of the second bracket 132-1 may increase, and first display panel 120-1 may be moved to the left side by about 0.5 mm. Here, specific numerals such as 0.5 mm are merely one example, and the embodiment is not limited thereto.
That is, the display panel 120 may be moved minutely to the left side by rotating the second adjustment bolt 132-3 in the clockwise direction, or the display panel 120 may be moved minutely to the right side or stopped by rotating in the anti-clockwise direction.
Different from the above-described example, based on the second position adjusting member 132 being disposed adjacent to the left side end of the display apparatus 100, the display panel 120 may be moved minutely to the right side by rotating the second adjustment bolt 132-3 in the clockwise direction, or the display panel 120 may be moved minutely to the left side or stopped by rotating the second adjustment bolt 132-3 in the anti-clockwise direction.
Accordingly, the interval space present between the other display panels 120′ which are disposed adjacent to the display panel 120 may be minimized by appropriately rotating the second adjustment bolt 132-3 in the clockwise direction or the anti-clockwise direction.
Referring back to
The second adjustment bolt 132-3 may be configured to directly contact with the one surface of the second bracket 132-1 through any one of the at least two through holes 132-4.
According to an embodiment, any one of the at least two second position adjusting members 132 may be disposed adjacent to an upper side end of the back surface of the display panel 120, and the other may be disposed adjacent to a lower side end of the back surface of the display panel 120.
According to an embodiment, the rear surface of the display panel 120 may be attached to or detached from the front surface of the frame 110 by magnetic force.
For example, the plurality of first coupling members 141 disposed at the front surface of the frame 110 and the plurality of second coupling members 142 disposed at the rear surface (or, back surface) of the display panel 120 may be inter-coupled to be attachable or detachable by attractive force.
