[0112] The connecting projection (230) may include a first projection body (231) and a second projection body (232). The second projection body (232) may be spaced apart from the first projection body (231). For example, the second projection body (232) may be spaced apart from the first projection body (231) along a first direction (D1). For example, the first projection body (231) and the second projection body (232) may be arranged along an approximately horizontal direction (e.g., X direction). For example, the first projection body (231) may include a first projection (231a) protruding in one direction, and the second projection body (232) may include a second projection (231b) protruding in the opposite direction to the first projection (231a). For example, the first protrusion (231a) may protrude to the left, and the second protrusion (231b) may protrude to the right. For example, the shape of the first protrusion body (231) and the shape of the second protrusion body (232) may be symmetric to each other with respect to an axis extending substantially in the vertical direction (e.g., Y direction).

[0113] The first protrusion body (231) and the second protrusion body (232) can be configured to be elastically deformable. Thus, the distance between the first protrusion body (231) and the second protrusion body (232) can be varied. A detailed explanation thereof is provided below.

The second hook catch portion (242) may include the second hook hole (241). The second hook catch portion (242) may be provided to interfere with the second hook (332) received in the second hook hole (241).

[0117] Although the drawings show that there are multiple second hook holes (241) and second hook catch portions (242), according to the embodiments of the present disclosure, there is no limitation on the number of second hook holes (241) and second hook catch portions (242).

[0118] The chassis holder (200) may include a terminal bracket (250). The terminal bracket (250) may be provided to protect various terminals of the display device (1). The terminal bracket (250) may be provided to protect an input terminal (41, see FIG. 2) and / or a power terminal (42, see FIG. 2). The terminal bracket (250) may be provided to secure the input terminal (41, see FIG. 2) and / or the power terminal (42, see FIG. 2). The terminal bracket (250) may include a terminal hole (251) corresponding to the terminal (e.g., input terminal (41) and / or power terminal (42)). A terminal (e.g., input terminal (41) and / or power terminal (42)) may be inserted into the terminal hole (251). At least one terminal hole (251) may be provided. The number of terminal holes (251) may correspond to the number of terminals (e.g., input terminal (41) and / or power terminal (42)).

[0119] The terminal bracket (250) may extend from the holder body (210). For example, the terminal bracket (250) may extend approximately vertically from the third cover portion (213). For example, the terminal bracket (250) may extend rearward (e.g., in the -Z direction) from the third cover portion (213). Since the terminal bracket (250) is provided as part of the chassis holder (200), the display device (1) may not include a separate member for protecting the terminal. This reduces the number of parts of the display device (1).

The first extension (321) and the second extension (322) may be configured to be approximately right angles to each other. For example, the first extension (321) and the second extension (322) may be arranged to be connected at the corner (312a) of the wall (312).

[0126] Although the drawing shows two ribs (320), according to the embodiment of the present disclosure, there is no limitation on the number of ribs (320).

[0127] The rear cover (300) may include at least one hook (330). At least one hook (330) may be formed on the cover frame (310). At least one hook (330) may be provided to be detachably coupled to the chassis (100) and / or the chassis holder (200). At least one hook (330) may be fixed to the chassis (100) and / or the chassis holder (200). At least one hook (330) may include at least one first hook (331) and at least one second hook (332).

[0128] The rear cover (300) may include a first hook (331). The first hook (331) may be provided to correspond to a first hook hole (141, see FIG. 6 and FIG. 7) of the chassis (100). The first hook (331) may be received in the first hook hole (141) of the chassis (100). The first hook (331) may be provided to be insertable into the first hook hole (141). The first hook (331) may be inserted into the first hook hole (141) and come into contact with a first hook catch (142).

[0129] The first hook (331) may be formed on the cover frame (310). The first hook (331) may be formed on the wall portion (312). The first hook (331) may protrude from the wall portion (312). For example, the first hook (331) may be formed on the inner surface of the wall portion (312). For example, the first hook (331) may be formed on the upper inner surface and the inner surfaces of both side portions of the wall portion (312).

[0130] In the drawings, a plurality of first hooks (331) are shown spaced apart along the inner surface of the wall (312), but the embodiments of the present disclosure are not limited to those shown in the drawings. There are no limitations on the position and number of the first hooks (331).

[0131] The rear cover (300) may include a second hook (332). The second hook (332) may be spaced apart from the first hook (331). The second hook (332) may be provided to correspond to the second hook hole (241, see FIG. 6 and FIG. 7) of the chassis holder (200). The second hook (332) may be received in the second hook hole (241) of the chassis holder (200). The second hook (332) may be provided to be insertable into the second hook hole (241). The second hook (332) may be inserted into the second hook hole (241) and come into contact with the second hook catch (242).

[0132] The second hook (332) may be formed on the cover frame (310). The second hook (332) may be formed on the wall portion (312). The second hook (332) may protrude from the wall portion (312). For example, the second hook (332) may be formed on the inner surface of the wall portion (312).

[0133] In the drawings, a plurality of second hooks (332) are shown spaced apart along the inner surface of the wall (312), but the embodiments of the present disclosure are not limited to those shown in the drawings. There are no limitations on the position and number of the second hooks (332).

[0134] The first hook (331) can be coupled to the chassis (100), and the second hook (332) can be coupled to the chassis holder (200). The first hook (331) and the second hook (332) differ only in the objects to which they are coupled, and the shape of the first hook (331) and the shape of the second hook (332) may be substantially identical to each other. However, the shape of the first hook (331) and the shape of the second hook (332) may be different from each other.

[0135] Next, the assembly process of a display device is described with reference to FIGS. 14 to 21. The disassembly (separation) process of the display device can be performed in the reverse order of the assembly process described with reference to FIGS. 14 to 21.

[0136] FIG. 14 illustrates a state in which a chassis holder is separated from a chassis in a display device according to an embodiment of the present disclosure. FIG. 15 illustrates a state in which a chassis holder is coupled to a chassis in a display device according to an embodiment of the present disclosure. FIG. 16 is a cross-sectional view along the line I-I' indicated in FIG. 15. FIG. 17 illustrates a state in which a rear cover is separated from a chassis and a chassis holder in a display device according to an embodiment of the present disclosure. FIG. 18 illustrates a state in which a rear cover is coupled to a chassis and a chassis holder in a display device according to an embodiment of the present disclosure. FIG. 19 is a cross-sectional view along the line II-II' indicated in FIG. 18. FIG. 20 is a cross-sectional view along the line III-III' indicated in FIG. 18. FIG. 21 is a cross-sectional view along the line IV-IV' indicated in FIG. 18.

[0137] Referring to FIGS. 14 to 16, the chassis holder (200) is coupleable to the chassis (100).

[0138] The chassis holder (200) can be coupled to the chassis (100) (see arrow S in FIG. 14) or separated from the chassis (100) by sliding relative to the chassis (100). For example, the chassis holder (200) is movable by sliding relative to the chassis (100) along approximately a second direction (D2).

[0139] As the coupling projection (230) of the chassis holder (200) is inserted into the coupling hole (131) of the chassis (100), the chassis holder (200) can be coupled to the chassis (100). As the coupling projection (230) of the chassis holder (200) is separated from the coupling hole (131) of the chassis (100), the chassis holder (200) can be separated from the chassis (100).

[0140] The coupling projection (230) can be elastically deformed to be inserted into the coupling hole (131). For example, while the coupling projection (230) is being inserted into the coupling hole (131), the distance between the first projection body (231) and the second projection body (232) can be reduced (see the dashed line in FIG. 16). For example, when the coupling projection (230) is fully inserted into the coupling hole (131), the distance between the first projection body (231) and the second projection body (232) can be returned to its original state (see the solid line in FIG. 16). Conversely, the coupling projection (230) received in the coupling hole (131) can be elastically deformed to be removed from the coupling hole (131). For example, while the coupling projection (230) is being separated from the coupling hole (131), the distance between the first projection body (231) and the second projection body (232) may be reduced (see the dashed line in FIG. 16). For example, when the coupling projection (230) is completely separated from the coupling hole (131), the distance between the first projection body (231) and the second projection body (232) may return to its original state.

[0141] While the chassis holder (200) is coupled to the chassis (100), the coupling projection (230) can be received in the coupling hole (131). The coupling projection (230) received in the coupling hole (131) may interfere with the projection catch (132). The coupling projection (230) received in the coupling hole (131) may not easily detach from the coupling hole (131) by the projection catch (132). Additionally, the movement of the coupling projection (230) received in the coupling hole (131) in the first direction (D1), second direction (D2), and third direction (D3) may be restricted by the projection catch (132). By doing so, the coupling force between the chassis (100) and the chassis holder (200) can be increased.

[0142] While the chassis holder (200) is coupled to the chassis (100), the first rib hole (120) of the chassis (100) and the second rib hole (220) of the chassis holder (200) may be arranged to correspond. When the chassis (100) and the chassis holder (200) are coupled, the first rib hole (120) of the chassis (100) and the second rib hole (220) of the chassis holder (200) may overlap.

[0143] While the chassis holder (200) is coupled to the chassis (100), the terminal bracket (250) of the chassis holder (200) may correspond to a terminal (e.g., input terminal (41) and / or power terminal (42)) of the second printed circuit board (40). A terminal (e.g., input terminal (41) and / or power terminal (42)) may be inserted into the terminal hole (251) of the chassis holder (200).

[0144] As the chassis holder (200) is coupled to the chassis (100), the chassis holder (200) can cover the first printed circuit board (30) mounted on the chassis (100). As the chassis holder (200) is coupled to the chassis (100), the chassis holder (200) can cover the film cable (50). The film cable (50) can be bent to connect the display panel (20) and the first printed circuit board (30). For example, the film cable (50) can have a roughly 'U' shape. While the chassis holder (200) is coupled to the chassis (100), the chassis holder (200) can cover the front side (51), bottom side (52), and rear side (53) of the film cable (50). Thus, the chassis holder (200) prevents the first printed circuit board (30) and the film cable (50) from being exposed to the outside and can protect the first printed circuit board (30) and the film cable (50).

[0145] Referring to FIGS. 17 to 21, the rear cover (300) is coupleable to the chassis (100) and the chassis holder (200). After the chassis holder (200) is coupled to the chassis (100), the rear cover (300) can be coupled to the rear side of the chassis (100) and the rear side of the chassis holder (200).

[0146] The rear cover (300) can be coupled to the chassis (100) and the chassis holder (200) while moving toward the chassis (100) and the chassis holder (200). The rear cover (300) can be coupled to the rear side (100a) of the chassis (100) and the rear side (200a) of the chassis holder (200) by moving approximately forward. The guide groove (103) of the chassis (100) can guide the position of the rear cover (300).

[0147] The hook (330) of the rear cover (300) can be coupled to the chassis (100) and the chassis holder (200). The first hook (331) can be received in the first hook hole (141) and interfere with the first hook catch (142). For example, the first hook (331) and the first hook catch (142) can be arranged to come into contact in a third direction (D3) (see FIG. 19). Since the first hook (331) is configured to be caught on the first hook catch (142) while received in the first hook hole (141), movement in the third direction (D3) may be restricted. Likewise, the second hook (332) can be received in the second hook hole (241) and interfere with the second hook catch (242). For example, the second hook (332) and the second hook catch (242) may be arranged to make contact in a third direction (D3). The second hook (332) is configured to be caught on the second hook catch (242) while being received in the second hook hole (241), thereby restricting movement in the third direction (D3).

[0148] While the rear cover (300) is coupled to the chassis (100) and the chassis holder (200), the rib (320) can be inserted into the first rib hole (120) of the chassis (100) and the second rib hole (220) of the chassis holder (200). The rib (320) can be inserted into the second rib hole (220) and the first rib hole (120) by being received into the first rib hole (120) through the second rib hole (220). The rib (320) can be placed within the first rib hole (120) and the second rib hole (220).

[0149] The rib (320) may include a first extension (321) extending in a first direction (D1) and a second extension (322) extending in a second direction (D2). With this shape, movement of the rib (320) in the first direction (D1) and movement in the second direction (D2) may be restricted while it is received in the first rib hole (120) and the second rib hole (220). For example, the first extension (321) may be restricted from moving in the first direction (D1) while it is received in the first rib hole (120) and the second rib hole (220). For example, the second extension (322) may be restricted from moving in the second direction (D2) while it is received in the first rib hole (120) and the second rib hole (220).

[0150] As the rear cover (300) is coupled to the chassis (100) and the chassis holder (200), the rear cover (300) can cover the second printed circuit board (40) mounted on the chassis (100). The rear cover (300) can prevent the second printed circuit board (40) from being exposed to the outside and can protect the second printed circuit board (40).

[0151] Generally, components supporting the display panel and / or backlight unit can be joined using screws. Consequently, in the comparative embodiment, the structure of the display device becomes complex and the number of components in the display device may increase. Furthermore, the assembly of the display device in the comparative embodiment may require significant time and cost. Meanwhile, the components supporting the display panel and / or backlight unit in the comparative embodiment may easily detach due to external shocks or vibrations. For example, assuming the display device in the comparative embodiment includes a first component, a second component, and a third component, a method in which the first component is joined to the second component and the first component is joined to the third component may generally be used. When the first component, the second component, and the third component are assembled, their respective errors accumulate, resulting in an increased cumulative tolerance. Consequently, the assembly quality of the display device in the comparative embodiment may be degraded.

[0152] In contrast, according to an embodiment of the present disclosure, the chassis (100), chassis holder (200), and rear cover (300) of the display device (1) can be assembled without screws. This makes the structure of the display device (1) simpler and reduces the number of parts of the display device (1). Additionally, the productivity of the display device (1) can be improved. According to an embodiment of the present disclosure, the rib (320) can be inserted into the overlapping first rib hole (120) and second rib hole (220) at once. As the rib (320) is inserted into the first rib hole (120) and the second rib hole (220) at once, the positions of the rear cover (300), chassis (100), and chassis holder (200) can be adjusted. Thus, when assembling the chassis (100), chassis holder (200), and rear cover (300), the cumulative tolerance can be reduced compared to the method of the comparative embodiment. Additionally, since the rib (320) is simultaneously received in the first rib hole (120) and the second rib hole (220), the bonding force of the chassis (100), chassis holder (200), and rear cover (300) can be increased. With the rib (320) received in the first rib hole (120) and the second rib hole (220), movement in the first direction (D1) and movement in the second direction (D2) can be restricted (see FIG. 20 and FIG. 21). The chassis (100), chassis holder (200), and rear cover (300) can be prevented from being easily separated by external impact or vibration. Consequently, the assemblability of the display device (1) can be increased.
