[0052] Hereinafter, embodiments according to the present invention will be described in detail with reference to the attached drawings.

[0053] FIG. 1 is a perspective view illustrating a substrate attached to the rear of a rear chassis according to one embodiment.

[0054] As illustrated in FIG. 1, the display device may be a curved display device. The display device may include an analog TV, a digital TV, a 3D TV, a smart TV, an LED (light emitting diode) TV, an OLED (organic light emitting diode) TV, a plasma TV, a quantum dot TV, and / or a monitor. However, the display device is not limited to a curved display device. That is, the display device may be a flat display device.

[0055] The display device may include a display module that displays image information and a stand (not shown) that rotatably supports the display module.

[0056] The display module may include a display panel (not shown) for displaying an image, a backlight unit (not shown) including a light source module (not shown) arranged on the rear side of the display panel to emit light to the display panel, and a rear chassis (10) arranged on the rear side of the backlight unit, which is the rear side of the display panel, to which the display panel and the backlight unit are fixed. The rear chassis (10) may form the rear exterior of the display device.

[0057] A plurality of substrates (100) may be fastened to the rear of the rear chassis (10). Although only one substrate (100) is shown fastened to the rear of the rear chassis (10) in the drawing, this is only to show that the substrate (100) is fastened to the rear of the rear chassis (10), and a plurality of substrates (100) may be fastened to the rear of the rear chassis (10). The plurality of substrates (100) fastened to the rear of the rear chassis (10) may control the operation of the display panel and the light source module, or supply power to the display panel and the light source module.

[0058] FIG. 2 is an enlarged view of part A of FIG. 1. FIG. 3 is a drawing illustrating a substrate being fastened to the rear surface of a rear chassis according to one embodiment. FIG. 4 is an enlarged view illustrating a portion of the rear surface of a rear chassis according to one embodiment where a substrate is fastened. FIG. 5 is a drawing illustrating a substrate according to one embodiment.

[0059] As shown in FIGS. 2 to 5, a substrate (100) can be fastened to the rear of the rear chassis (10). The substrate (100) can be fastened by sliding to the rear of the rear chassis (10).

[0060] The rear chassis (10) may include an insertion rib (20) that forms an insertion space (21) into which a substrate (100) is slidably inserted. A plurality of insertion ribs (20) may be provided. Each of the plurality of insertion ribs (20) may form an insertion space (21). The plurality of insertion ribs (20) may cover the upper portion of the substrate (100) inserted into the insertion space (21). An insertion portion (110) of the substrate (100) may be inserted into the insertion space (21) formed by the insertion rib (20). The upper surface of the insertion portion (110) inserted into the insertion space (21) may be covered by the insertion rib (20). That is, the insertion portion (110) may be provided to have an area corresponding to the insertion rib (20) that covers the upper surface of the insertion portion (110). Due to this, the insertion portion (110) can occupy only a minimum area of ​​the entire area of ​​the substrate (100). Although the drawing shows that four insertion ribs (20) are formed, this is not a limitation. That is, as long as the substrate (100) can be slidably fastened to the rear of the rear chassis (10), the number of insertion ribs (20) may not be limited.

[0061] As described above, since the substrate (100) is not fastened to the rear of the rear chassis (10) by screws or lugs, but is inserted into the insertion space (21) by a sliding method and fastened to the rear of the rear chassis (10), material costs can be reduced. In addition, since the substrate (100) is fastened to the rear of the rear chassis (10) by a sliding method, the process cost of a worker for fastening the substrate (100) to the rear of the rear chassis (10) can be reduced. In addition, since the substrate (100) is fastened to the rear of the rear chassis (10) by a sliding method, the work time for fastening the substrate (100) to the rear of the rear chassis (10) can be reduced, thereby improving productivity.

[0062] The rear chassis (10) may include a fixing projection (30) that fixes a substrate (100) that is slidably inserted into the insertion space (21). The fixing projection (30) may be fixed to a fixing groove (120) of the substrate (100). The substrate (100) that is slidably inserted into the insertion space (21) may be prevented from moving because the fixing groove (120) is fixed to the fixing projection (30) of the rear chassis (10). That is, after the substrate (100) is slidably fixed to the rear of the rear chassis (10), it may be prevented from being separated from the insertion space (21) by sliding again in the opposite direction of the direction in which the substrate (100) is fixed due to impact or the weight of the substrate (100).

[0063] The rear chassis (10) may include a guide protrusion (40) that guides the substrate (100) so that the substrate (100) is slidably inserted into the insertion space (21). The guide protrusion (40) may be inserted into a guide hole (130) of the substrate (100). The guide hole (130) may be formed to be long in the direction in which the substrate (100) is inserted into the insertion space (21) so that the substrate (100) is guided by the guide protrusion (40) when the insertion portion (110) of the substrate (100) is inserted into the insertion space (21) of the rear chassis (10). That is, the guide hole (130) may be formed to be long in the direction in which the substrate (100) is slid when the substrate (100) is fastened to the rear surface of the rear chassis (10). Since the substrate (100) is guided by the guide protrusion (40) of the rear chassis (10) and the guide hole (130) of the substrate (100), when the substrate (100) is inserted into the insertion space (21), the insertion portion (110) of the substrate (100) can be inserted into the insertion space (21) without being caught by the insertion rib (20) of the rear chassis (10). The guide protrusions (40) can be provided in a pair. The guide holes (130) can be provided in a pair so as to correspond to the number of guide protrusions (40).

[0064] The substrate (100) may include an insertion portion (110) to be inserted into the insertion space (21) of the rear chassis (10). The insertion portion (110) may be inserted by sliding into the insertion space (21) formed by the insertion rib (20) provided on the rear side of the rear chassis (10). The insertion portion (110) may be provided on the edge of the substrate (100). A plurality of insertion portions (110) may be provided to correspond in number to a plurality of insertion ribs (20). The insertion portion (110) may be provided to have an area corresponding to the insertion rib (20) that covers the upper surface of the insertion portion (110) when the insertion portion (110) is inserted into the insertion space (21) of the rear chassis (10). The insertion portion (110) may be a portion where the configuration of circuit components (not shown) and patterns (not shown) provided on the substrate (100) is limited. The insertion portion (110) can be formed only in the portion inserted into the insertion space (21) on the edge of the substrate (100). As a result, the insertion portion (110) can occupy only an area equivalent to the portion inserted into the insertion space (21) out of the entire area of ​​the substrate (100).

[0065] As described above, since the area of ​​the insertion portion (110) occupies only a minimal area of ​​the entire area of ​​the substrate (100), the size of the substrate (100) can be minimized. Since the size of the substrate (100) is minimized, material costs can be reduced. In addition, sufficient space can be secured for the substrate (100) to be placed. In addition, sufficient space can be secured for the cable (not shown) placed on the rear of the rear chassis (10).

[0066] The substrate (100) may include a fixing groove (120) that is fixed to the fixing projection (30) of the rear chassis (10). After the substrate (100) is slid and the insertion portion (110) is inserted into the insertion space (21), the fixing groove (120) is fixed to the fixing projection (30) of the rear chassis (10) to prevent movement. That is, after the substrate (100) is slid and fixed to the rear of the rear chassis (10), the substrate (100) may be prevented from being separated from the insertion space (21) by sliding again in the opposite direction of the direction in which it is fixed due to impact or the weight of the substrate (100).

[0067] When the direction in which the substrate (100) is inserted into the insertion space (21) is referred to as the upper direction, the fixing groove (120) may be provided in one position at the center of the lower edge of the substrate (100). The fixing projection (30) of the rear chassis (10) may be provided in one position at which the fixing groove (120) can be fixed when the insertion portion (110) of the substrate (100) is inserted into the insertion space (21).

[0068] The substrate (100) may include a guide hole (130) into which a guide protrusion (40) of the rear chassis (10) is inserted. The guide hole (130) may be formed to be long in the direction in which the substrate (100) slides when the substrate (100) is fastened to the rear of the rear chassis (10). The guide hole (130) may allow the substrate (100) to be guided by the guide protrusion (40) when the insertion portion (110) of the substrate (100) is inserted into the insertion space (21) of the rear chassis (10). Since the substrate (100) is guided by the guide hole (130) of the substrate (100) and the guide protrusion (40) of the rear chassis (10), when the substrate (100) is inserted into the insertion space (21), the insertion portion (110) of the substrate (100) can be inserted into the insertion space (21) without being caught by the insertion rib (20) of the rear chassis (10). The guide holes (130) can be provided in a pair. The guide protrusions (40) can be provided in a pair so as to correspond to the number of guide holes (130).

[0069] The substrate (100) may include an insertion hole (140) into which a fixing projection (30) of the rear chassis (10) is inserted before the substrate (100) is slidably inserted into the insertion space (21). Since the fixing projection (30) of the rear chassis (10) is inserted into the insertion hole (140) before the substrate (100) is inserted into the insertion space (21), the substrate (100) can be prevented from being lifted by the fixing projection (30). If the substrate (100) is lifted by the fixing projection (30), the insertion portion (110) may be caught on the insertion rib (20) when the substrate (100) is slidably inserted into the insertion space (21) of the rear chassis (10). However, since the fixing protrusion (30) of the rear chassis (10) is inserted into the insertion hole (140) before the substrate (100) is inserted into the insertion space (21), the substrate (100) can be easily inserted into the insertion space (21). Since the fixing protrusion (30) is inserted into the insertion hole (140), the insertion hole (140) can be located above the fixing groove (120). That is, when the substrate (100) is slid upward while the fixing protrusion (30) of the rear chassis (10) is inserted into the insertion hole (140) located relatively above the substrate (100), the fixing protrusion (30) can be removed from the insertion hole (140) and then inserted into the fixing groove (120), thereby preventing the substrate (100) from moving.

[0070] A connector (C) to which a cable (not shown) connected to the display panel and the light source module is connected may be mounted on the substrate (100) so that the substrate (100) can control the operation of the display panel and the light source module or supply power to the display panel and the light source module.

[0071] The substrate (100) may include a protruding rib (150) protruding from the connector (C) so that the substrate (100) can be pushed without touching the connector (C) when the substrate (100) is pushed to insert the substrate (100) into the insertion space (21) of the rear chassis (10). Since the substrate (100) is pushed by touching the protruding rib (150) protruding from the connector (C) without touching the connector (C) when the substrate (100) is pushed, damage to the connector (C) can be prevented.

[0072] Next, with reference to FIGS. 6 and 7, the operation of attaching the substrate (100) to the rear of the rear chassis (10) will be described.

[0073] FIG. 6 is a drawing illustrating a substrate being fastened to a rear chassis according to one embodiment. FIG. 7 is a drawing illustrating a substrate being fastened to a rear chassis according to one embodiment.

[0074] As illustrated in FIG. 6, before the substrate (100) is fastened to the rear chassis (10), the fixing protrusion (30) of the rear chassis (10) may be inserted into the insertion hole (140) of the substrate (100). By ensuring that the fixing protrusion (30) of the rear chassis (10) is inserted into the insertion hole (140) of the substrate (100) before the substrate (100) is fastened to the rear chassis (10), the substrate (100) can be prevented from being lifted.

[0075] In addition, before the substrate (100) is fastened to the rear chassis (10), the guide protrusion (40) of the rear chassis (10) may be inserted into the guide hole (130) of the substrate (100). At this time, the guide protrusion (40) may be located on the upper side of the guide hole (130). Here, the upper side may be the direction in which the substrate (100) slides into the insertion space (21), which is the direction of the arrow shown in the drawing.

[0076] In a state where the fixing protrusion (30) of the rear chassis (10) is inserted into the insertion hole (140) of the substrate (100) and the guide protrusion (40) of the rear chassis (10) is inserted into the upper side of the guide hole (130) of the substrate (100), the substrate (100) can be slidably moved in the direction of the arrow shown in the drawing to fasten the substrate (100) to the rear chassis (10). At this time, the worker can push the protruding rib (150) of the substrate (100) to prevent damage to the connector (C).

[0077] When the protruding rib (150) of the substrate (100) is pushed to slide the substrate (100) in the direction of the arrow shown in the drawing, the insertion portion (110) of the substrate (100) can be inserted into the insertion space (21) formed by the insertion rib (20). At this time, the substrate (100) can be guided and moved by the guide protrusion (40) inserted into the guide hole (130).

[0078] As illustrated in Fig. 7, when the insertion portion (110) of the substrate (100) is inserted into the insertion space (21), the fixing groove (120) of the substrate (100) is fixed to the fixing protrusion (30) of the rear chassis (10), so that the substrate (100) can be fastened to the rear chassis (10). At this time, the guide protrusion (40) of the rear chassis (10) can be located on the lower side of the guide hole (130) of the substrate (100).

[0079] Fig. 8 is a drawing illustrating a substrate having a single guide hole according to one embodiment. Fig. 9 is a drawing illustrating a state in which the substrate illustrated in Fig. 8 is fastened to a rear chassis according to one embodiment.

[0080] As illustrated in FIGS. 8 and 9, the substrate (200) may include a single guide hole (230). The rear chassis (10) to which the substrate (200) is fastened may include a single guide protrusion (41) corresponding to the number of guide holes (230) provided.

[0081] Other configurations for fastening the substrate (200) to the rear chassis (10) other than the configuration in which the rear chassis (10) includes one guide protrusion (41) and the substrate (200) includes one guide hole (230) may be the same as the configurations of the substrate (100) and the rear chassis (10) illustrated in FIGS. 1 to 7.

[0082] That is, the rear chassis (10) may include a plurality of insertion ribs (20) that form an insertion space (21) into which the substrate (200) is slidably inserted. The rear chassis (10) may include a fixing protrusion (30) that fixes the substrate (200) that is slidably inserted into the insertion space (21). The rear chassis (10) may include a guide protrusion (41) that guides the substrate (200) so that the substrate (200) is slidably inserted into the insertion space (21).

[0083] The substrate (200) may include an insertion portion (210) to be inserted into an insertion space (21) of the rear chassis (10). The substrate (200) may include a fixing groove (220) to be fixed to a fixing protrusion (30) of the rear chassis (10). The substrate (200) may include a guide hole (230) into which a guide protrusion (41) of the rear chassis (10) is inserted and into which the substrate (200) is guided by the guide protrusion (41). The substrate (200) may include an insertion hole (240) into which a fixing protrusion (30) of the rear chassis (10) is inserted before the substrate (200) is slidably inserted into the insertion space (21). The substrate (200) may include a protruding rib (250) that protrudes beyond the connector (C) so that the substrate (200) can be pushed without touching the connector (C) when the substrate (200) is pushed to insert the substrate (200) into the insertion space (21) of the rear chassis (10).

[0084] As described above, since the configurations other than the configuration in which the rear chassis (10) includes one guide protrusion (41) and the substrate (200) includes one guide hole (230) are the same as the configurations of the substrate (100) and the rear chassis (10) illustrated in FIGS. 1 to 7, when the substrate (200) is fastened to the rear chassis (10), the operation may be the same as the operation in which the substrate (100) illustrated in FIGS. 6 to 7 is fastened to the rear chassis (10) except for the portion in which one guide hole (230) is guided by one guide protrusion (41).

[0085] FIG. 10 is a drawing illustrating a state in which an insertion portion of a substrate is provided adjacent to a border of the substrate according to one embodiment. FIG. 11 is a drawing illustrating a state in which the substrate illustrated in FIG. 10 is fastened to a rear chassis according to one embodiment. FIG. 12 is a drawing illustrating a state in which the substrate illustrated in FIG. 10 is fastened to a rear chassis according to one embodiment.

[0086] As illustrated in FIGS. 10 to 12, when the size of the substrate (300) is large, the insertion portion (310) of the substrate (300) may be provided in a portion adjacent to the edge of the substrate (300) rather than at the edge of the substrate (300). This may be to correspond the position of the insertion portion (310) of the substrate (300) to the insertion space (21) of the rear chassis (10) into which the insertion portion (310) of the substrate (300) is inserted. Other configurations of the substrate (300) except for the position of the insertion portion (310) of the substrate (300) may be the same as the configuration of the substrate (100) illustrated in FIGS. 1 to 7.

Since the substrate (100, 200, 300, 400, 500) is fastened to the rear of the rear chassis (10) by a sliding method, the process cost of a worker for fastening the substrate (100, 200, 300, 400, 500) to the rear of the rear chassis (10) can be reduced. Since the substrate (100, 200, 300, 400, 500) is fastened to the rear of the rear chassis (10) by a sliding method, the work time for fastening the substrate (100, 200, 300, 400, 500) to the rear of the rear chassis (10) can be reduced, thereby improving productivity.
