A bottom frame 70 may be provided between a pair of panel holders 100 and a pair of support frames 110. The bottom frame 70 may be provided at a central lower portion of the rear chassis 40. The bottom frame 70 may be provided with a fastening hole 71 which a fastening member, such as a screw, passes through. Since the fastening hole 71 of the bottom frame 70 is covered by the rear cover 50, the lower end of the display panel 10 may be coupled to the lower end of the rear chassis 40 using a fastening member, such as a screw, as in the related art.
On the other hand, in the case of both side ends of the rear chassis 40 that are not covered by the rear cover 50, the rear chassis 40 forms the rear external appearance of the display apparatus 1. For a neat appearance, a fastening hole or the like may not be provided in the rear chassis 40 exposed to the outside.
According to the aspect of the disclosure, it is possible to provide a structure in which both side ends of the rear chassis 40 are detachably coupled to both side ends of the display panel 10 corresponding thereto without including a fastening hole. More specifically, as the panel holder 100 coupled to the rear surface of the display panel 10 and the support frame 110 coupled to the front surface of the rear chassis 40 are coupled to and released from each other, the display panel 10 may be coupled to or detached from the rear chassis 40.
Referring to
The panel holder 100 may be provided adjacent to the lower end of the display panel 10. In addition, the panel holders 100 may be provided as a pair and provided on one side and the other side of the display panel 10, respectively.
The support frame 110 may be coupled to the front surface of the rear chassis 40 to correspond to the panel holder 100. The support frame 110 may be provided adjacent to the lower end of the rear chassis 40.

The first protrusion 112 may be provided to be inserted into the first hole 102 of the panel holder 100, and come in contact with a first portion of the wire 130 to support the first portion. The second protrusion 113 may be provided to be inserted into the third hole 105 of the panel holder 100 to engage with the protrusion support 106 of the panel holder 100. As the second protrusion 113 and the protrusion support 106 are engaged with each other, the panel holder 100 may not be separated from the support frame 110 in the forward direction.
Referring to
When the wire 130 is coupled to the panel holder 100 and the support frame 110, upward movement of the panel holder 100 with respect to the support frame 110 may be restricted. In addition, as the first portion of the wire 130 is supported by the panel holder 100, and a second portion different from the first portion of the wire 130 is supported by the support frame 110, the panel holder 100 and the support frame 110 may be fixed without being moved in the front-rear direction.
More specifically, the first portion of the wire 130 may be supported by the first protrusion 112 of the support frame 110, and the second portion of the wire 130 may be accommodated in the wire accommodating groove 103. The second portion of the wire 130 may be supported by one surface of the panel holder 100 forming the wire accommodating groove 103. The second portion of the wire 130 may indicate a pair of points provided on both sides of the first portion of the wire 130. The first protrusion 112 supporting the first portion of the wire 130 may be spaced apart from the wire accommodating groove 103 supporting the second portion of the wire 130 in the front-rear direction. Since the first portion of the wire 130 supported by the first protrusion 112 is spaced apart from the second portion of the wire 130 supported by the wire accommodating groove 103 in the front-rear direction, the wire 130 may be bent. By the wire 130 being bent, the panel holder 100 may be coupled to the support frame 110 by the tension of the wire 130 without a gap in the front-rear direction.
Referring to
A process in which the panel holder 100 is coupled to the support frame 110 will be described with reference to
Referring to
When the panel holder 100 is coupled to the support frame 110, the wire 130 may be coupled to the panel holder 100 first. With the wire 130 coupled to the panel holder 100, the panel holder 100 may be coupled to the support frame 110.

According to an embodiment, the display panel 10 and the substrate 13 attached to the display panel 10 may be separated from the rear chassis 40 without damage to the display panel 10.
According to an example embodiment, adhesive members may be provided on the upper surface and both side surfaces of the display panel 10 to couple the upper surface and both side surfaces of the display panel 10 to the rear chassis 40. The type of the adhesive member is not limited, but may be, for example, a double-sided tape.
When the adhesive members provided on the upper surface and both side surfaces of the display panel 10 are separated, and then the panel holder 100 provided on the lower surface of the display panel 10 is separated from the support frame 110, the display panel 10 may be separated from the rear chassis 40 without damaging the display panel 10. When the couplings on the four sides of the display panel 10 are removed, since the rear surface of the heat dissipation sheet 20 and the front surface of the rear chassis 40 are separable from each other as described above, the display panel 1 may be separable from the rear chassis 40 in the forward direction. Accordingly, it is possible to disassemble and replace the display panel 10 including the light-emissive panel 11.
In the following description, details of redundant description will be omitted.
Referring to
More specifically, the panel holder 200 may be coupled to the support frame 210 by slidably moving with respect to the support frame 210 in the first direction. Conversely, the panel holder 200 may be separated from the support frame 210 by slidably moving with respect to the support frame 210 in the second direction opposite to the first direction. According to an embodiment, the first direction may refer to the downward direction, and the second direction may refer to the upward direction.
The panel holder 200 may be coupled to the lower end of the rear surface of the display panel 10. The support frame 210 may be coupled to the lower end of the front surface of the rear chassis 40. By moving the display panel 10 upward with respect to the rear chassis 40, the display panel 10 may be separated from the rear chassis 40 in the forward direction.
Referring to
The support frame 210 may include a first hole 211 having an area larger than the first area so that the head portion 201A of the panel holder 200 may pass through the first hole 211, and a second hole 212 having an area smaller than the first area and larger than the second area. The first hole 211 and the second hole 212 may be consecutively arranged in the vertical direction.
With the above structure, the head portion 201A of the coupling protrusions 201 may be inserted into the first hole 211. The head portion 201A inserted into the first hole 211 may slide downward. When the head portion 201A slides downward, the connecting portion 201B is inserted into the second hole 212, and because the head portion 201A does not pass through the second hole 212, the panel holder 200 and the support frame 210 may be coupled to each other.
Conversely, when the panel holder 200 slides upward with the connecting portion 201B inserted into the second hole 212, the connecting portion 201B is drawn out of the second hole 212, and the head portion 201A is inserted into the first hole 211, so that the panel holder 200 may be separable from the support frame 210 in the forward direction.
As is apparent from the above description, a display apparatus including a display panel that is allowed to be disassembled and replaced without damage can be provided.
A display apparatus having an ultra-slim appearance can be provided by reducing the size of a rear cover, which is the thickest part of the display apparatus.
A display apparatus allowing a display panel, of which a rear surface is coupled to a substrate, to be detachably coupled to a rear chassis can be provided.
Although the disclosure has been shown and described in relation to specific embodiments, it would be appreciated by those skilled in the art that changes and modifications may be made in these embodiments without departing from the principles and scope of the disclosure, the scope of which is defined in the claims and their equivalents.
