[0063] The light source included in the light assembly (124) may be a COB (Chip On Board) type. The COB type may be a form in which an LED chip, which is a light source, is directly bonded to the substrate (122). This can simplify the manufacturing process. In addition, resistance can be lowered, thereby reducing energy lost as heat. In other words, this means that the power efficiency of the light assembly (124) can be increased. The COB type can provide brighter lighting. The COB type can provide a thinner thickness and lighter weight than conventional types.

[0064] A reflective sheet (126) may be positioned on the front surface of the substrate (122). The reflective sheet (126) may have a through hole (235), and the optical assembly may be inserted into the through hole (235).

The first optical sheet (125a) may have the function of a diffusion sheet, and the second and third optical sheets (125b, 125c) may have the function of prism sheets. The number and / or positions of the diffusion sheets and prism sheets may be changed.

[0073] The diffusion sheet can prevent light from being partially concentrated from the diffusion plate, thereby making the light distribution more uniform. The prism sheet can collect light from the diffusion sheet, thereby allowing the light to be vertically incident on the display panel (110).

[0074] The coupling portion (125d) may be formed on at least one side or edge of the optical sheet (125). The coupling portion (125d) may be formed on at least one of the first to third optical sheets (125a to 125c).

The coupling portion (125d) formed on the first long side and the coupling portion (125d) formed on the second long side may be asymmetric. For example, this means that the positions and / or numbers of the coupling portions (125d) on the first long side and the coupling portions (125d) on the second long side may be different from each other.

[0076]

[0077] Referring to FIG. 4, a substrate (122) may be provided, which is composed of a plurality of straps extending in a first direction on a frame (130) and spaced apart at a predetermined interval in a second direction orthogonal to the first direction.

The second substrate (122B) may be elongated in the left-right direction (LR) of the frame (130) and may be mounted on the frame (130) while being spaced apart from the first substrate (122A). The third substrate (122C) may be elongated in the left-right direction (LR) of the frame (130) and may be mounted on the frame (130) while being spaced apart from the second substrate (122B).

[0084] The spacing between the substrates (122) may vary depending on the number of pixels of the display panel (110, see FIG. 2). For example, the spacing between the substrates (122) for providing light to a display panel (110) implementing 8K image quality may be smaller than the spacing between the substrates (122) for providing light to a display panel (110) implementing 4K image quality. If the number of pixels of the display panel (110) increases or the image quality that the display panel (110) can implement increases, the light transmittance of the display panel (110) may decrease. To this end, a large number of substrates (122) may be arranged to increase the brightness of the light provided by the backlight unit (120, see FIG. 3).

[0085] The reflective sheet (126) may include holes (235). The number of holes (235) may correspond to the number of the plurality of optical assemblies (124).

The second shoulder (2132) can extend upwardly from the other end of the second arm (2115) of the base (211) in an arch. The loop (2133) can connect the first shoulder (2131) and the second shoulder (2132).

[0098] The distance between the first shoulder (2131) and the base (211) and / or the distance between the second shoulder (2132) and the base (211) may be greater than the distance between the loop (2133) and the base (211). That is, the upper surface of the first shoulder (2131) and / or the upper surface of the second shoulder (2132) may protrude forward relative to the upper surface of the loop (2133). The first shoulder (2131), the second shoulder (2132), and / or the loop (2133) may have elasticity.

[0099] The tower (215) may extend from the upper surface of the roof (2133). The diameter of the tower (215) may gradually decrease along the extension direction. The tower (215) may have a cylindrical shape. For example, the tower (215) may have elasticity that allows it to bend easily, and rigidity that prevents it from bending.

[0100] The bottom (216) can form a step on the lower surface of the base (211). The bottom (216) can be formed on the lower surface of the body (2111) of the base (211). The step formed by the bottom (216) and the lower surface of the base (211) can correspond to the thickness of the reflective sheet (126).

[0101] The fixed bar (217) may include a shaft (2173) and a bar (2171). The bar (2171) may extend across the lower surface of the bottom (216) and may be spaced apart from the bottom (216). The shaft (2173) may extend from the lower surface of the bottom (216) toward the bar (2171).

[0102] When light is supplied to the display panel (110), the temperature applied to the diffuser (129) may increase, and deformation of the diffuser (129) may occur. For example, the deformation of the diffuser (129) may be sagging. When the diffuser (129) sags, the supporter (200) may support the diffuser (129). The lower surface of the diffuser (129) may contact the tower (215) of the supporter (200). Accordingly, deterioration of the image quality of the display device can be prevented.

[0103]

[0104] Referring to FIG. 8, a bar slot (1341, 1342), a shaft hole (1343), protrusion holes (1345, 1346), and a ramp (1347, 1348) may be formed in the frame (130).

[0105] The bar slots (1341, 1342) may have a shape corresponding to the shape of the bar (2171). The shaft hole (1343) is a hole in which the shaft (2173) is received and may be located between the bar slots (1341, 1342). The bar slots (1341, 1342) may be symmetrical with respect to the shaft hole (1343). The protrusion holes (1345, 1346) may be symmetrical with respect to the shaft hole (1343).

[0106] The virtual straight lines connecting the protrusion holes (1345, 1346) and the virtual straight lines connecting the bar slots (1341, 1342) may intersect each other. The protrusion holes (1345, 1346) may be formed at positions spaced apart from the positions of the respective bar slots (1341, 1342) in the rotational direction of the supporter (200). The protrusion holes (1345, 1346) may be referred to as hook holes, fixing holes, etc.

[0107] The lamps (1347, 1348) may be formed on one side of the bar slots (1341, 1342). The lamps (1347, 1348) may be symmetrical with respect to the shaft hole (1343). The lamps (1347, 1348) may be positioned on the rotational path of the protrusion (2172). When the fixed bar (217) rotates (see FIG. 9), the protrusion (2172) of the fixed bar (217) may be caught in the protrusion holes (1345, 1346) via the lamps (1347, 1348).

[0108] A press portion (131, 132) may be formed on the frame (130). The press portion (131, 132) may protrude toward the base (211) of the supporter (200). The heights at which the first press portion (131) and the second press portion (132) protrude from one surface of the frame (130) may be the same or different. The press portion (131, 132) may be formed by pressing using a forming method, and the method of forming the press portion (131, 132) is not limited thereto.

[0109] The press portion (131, 132) may protrude forward from the front of the frame (130). The rear surface of the frame (130) on which the press portion (131, 132) is formed may or may not be recessed forward. The press portion (131, 132) may be referred to as a mound, a support portion, a protrusion, etc.

[0110] The press section (131, 132) may include a first press section (131) and a second press section (132). The first press section (131) and the second press section (132) may be formed at positions symmetrical with respect to the shaft hole (1343). The first press section (131) and the second press section (132) may be covered by the base (211). The first press section (131) and the second press section (132) may be supported by contacting the base (211).

[0111] The sizes of the first press section (131) and the second press section (132) may be different from each other. The sizes of the surfaces formed by the first press section (131) and the second press section (132) protruding from the frame (130) may be different from each other.

[0112] The width (131w) of the first press portion (131) may be greater than the width (132w) of the second press portion (132). The widths (131w, 132w) of the first press portion (131) and the second press portion (132) may be defined in the direction in which the protrusion hole (1346) and the stopper (133) are spaced apart from each other. The direction in which the protrusion hole (1346) and the stopper (133) are spaced apart from each other may be understood as the tangential direction of the protrusion hole (1346) with respect to the shaft hole (1343).

[0113] The second press section (132) may be positioned adjacent to the stopper (133). The second press section (132) may have a smaller size than the first press section (131) due to the adjacent stopper (133).

[0114] The press portion (131, 132) may extend along the direction in which the shaft hole (1343) and the protrusion holes (1345, 1346) are spaced apart from each other. A portion (131s) of the circumference of the first press portion (131) adjacent to the bar slot (1341, 1342) may extend along the longitudinal direction of the bar slot (1341, 1342). Accordingly, the area where the base (211) and the press portion (131, 132) face each other may be maximized.

[0115] The stopper (133) can limit the rotation of the supporter (200). The stopper (133) can be formed between the second press portion (132) and the protrusion hole (1346). The stopper (133) can protrude in the opposite direction to the press portions (131, 132). When the supporter (200) is mounted on the frame (130), the stopper (133) can contact the side of the bar (2171) to limit the rotation of the supporter (200).

[0116]

[0117] FIGS. 9 and 10 are drawings showing the process of mounting the supporter (200) on the frame (130), and FIG. 11 is a drawing showing the supporter (200) mounted on the frame (130) as viewed from the opposite side, unlike FIG. 10. Referring to FIGS. 9 and 11, the supporter (200) can be inserted into the frame (130) and rotated to be coupled with the frame (130).

[0118] Specifically, the fixed bar (217) of the supporter (200) can be inserted into the bar slots (1341, 1342) and the shaft hole (1343). The inserted supporter (200) can be rotated based on the shaft hole (1343), and the protrusions (2172) formed on the fixed bar (217) can be inserted into the protrusion holes (1345, 1346). Accordingly, the supporter (200) can be firmly coupled to the frame (130).

[0119] When the fixed bar (217) of the supporter (200) passes through the bar slots (1341, 1342) and the shaft hole (1343), the first press part (131) and the second press part (132) can support the body (2111) of the base (211). The first press part (131) and the second press part (132) can support the body (2111) by contacting the body (2111) or being adjacent to the body (2111).

[0120] The base (211) may include protrusions (2113, 2114). The protrusions (2113, 2114) may be supported by the first press portion (131) and the second press portion (132), respectively. The contact area between the base (211) and the first press portion (131) and the second press portion (132) may be increased by the protrusions (2113, 2114).

[0121] The protrusions (2113, 2114) may protrude from the side of the body (2111). The protrusions (2113, 2114) may protrude in a direction intersecting the longitudinal direction of the arms (2115, 2116) of the base (211). For example, the protrusions (2113, 2114) may protrude in a direction perpendicular to the longitudinal direction of the arms (2115, 2116).

[0122] The supporter (200) may include a reflective board (2112). The reflective board (2112) may be placed on the body (2111) of the base (211). The reflective board (2112) may reflect light. As an example, the reflective board (2112) may include an opaque material that does not transmit light. As another example, the reflective board (2112) may be white.

[0123] The reflection board (2112) can minimize the difference in brightness caused by the bar slots (1341, 1342), shaft holes (1343), and protrusion holes (1345, 1346). By the reflection board (2112), light can be reflected toward the diffusion plate (129).

[0124] When the supporter (200) is formed of a transparent material, light reflected toward the supporter (200) by the diffuser (129) can pass through the supporter (200) and pass through the slots (1341, 1342), shaft holes (1343), and protrusion holes (1345, 1346).

[0125] Accordingly, since the light passing through the light source is not reflected back toward the diffuser plate (129), a difference in brightness may occur between the area corresponding to the slot (1341, 1342), the shaft hole (1343), and the protrusion holes (1345, 1346) and the surrounding area. The reflection board (2112) can minimize the difference in brightness by covering at least a part of the area corresponding to the slot (1341, 1342), the shaft hole (1343), and the protrusion holes (1345, 1346).

[0126] Meanwhile, the bar slot (1341), the protrusion hole (1346), the stopper (133), and the second press portion (132) can be arranged along the rotational direction of the supporter (200). In addition, the bar slot (1342), the protrusion hole (1345), and the first press portion (131) can be arranged along the rotational direction of the supporter (200). Therefore, the press portions (131, 132), the stopper (133), the bar slots (1341, 1342), and the protrusion holes (1345, 1346) can be compactly arranged with respect to the shaft hole (1343).

[0127]

[0128] Figures 12 and 13 are drawings comparing cases where the thicknesses (T1, T2) of the frames (130, 130') are different. Figure 12 illustrates a case where the thickness (T1) of the frame (130) is small, and Figure 13 illustrates a case where the thickness (T2) of the frame (130') is large. Referring to Figures 12 and 13, the heights (H1, H2) at which the press parts (131, 132) protrude from the frames (130, 130') may vary depending on the thicknesses (T1, T2) of the frames (130, 130').

[0129] The protrusion height (H1, H2) of the press portion (131, 132) may refer to the height at which the front of the press portion (131, 132) facing the rear surface of the base (211) protrudes from the front surface of the frame (130, 130'). The protrusion height (H1, H2) may vary during the manufacturing process of the frame (130, 130') and may be determined by considering the thickness (T1, T2) of the frame (130, 130').

[0130] The sum of the thickness (T1) of the frame (130) illustrated in FIG. 12 and the protrusion height (H1) of the press portion (131, 132) may be equal to the sum of the thickness (T2) of the frame (130') illustrated in FIG. 13 and the protrusion height (H2) of the press portion (131, 132).

[0131] Accordingly, even if the thickness of the frame (130, 130') varies depending on the type of display device, installation conditions, etc., the supporter (200) of the same specification can be used for various types of display devices by manufacturing the protrusion height of the press part (131, 132) differently.

[0132] Meanwhile, the first press part (131) and the second press part (132) may protrude in a direction opposite to the bottom (216) of the supporter (200). In addition, the first press part (131) and the second press part (132) may be spaced apart from the bottom (216) in the radial direction of the shaft (2173). The first press part (131) and the second press part (132) may support a portion of the rear surface of the body (2111) of the base (211) where the bottom (216) is not formed.

[0133]

[0134] Fig. 14 illustrates a reflective sheet (126) fixed to a frame (130). Referring to Fig. 14, a supporter (200) can be mounted on the frame (130) by penetrating the reflective sheet (126). The supporter (200) of the reflective sheet (126)

[0135] The reflective sheet (126) may include a through hole (1261) through which the supporter (200) passes and cut slits (1261, 1262). The cut slits (1261, 1262) may be connected to the through hole (1261). The cut slits (1261, 1262) may be formed by cutting from the through hole (1261) on both sides. The cut slits (1261, 1262) may be symmetrical with respect to the through hole (1261).

[0136] The through hole (1261) may be formed at a position corresponding to the shaft hole (1343) of the frame (130). The cut slits (1261, 1262) may be formed at positions corresponding to the bar slots (1341, 1342) of the frame (130). As the supporter (200) is inserted into the through hole (1261), the peripheral portion of the through hole (1261) is folded toward the frame (130) by the cut slits (1261, 1262), so that the fixing bar (217) of the supporter (200) can be smoothly inserted into the bar slots (1341, 1342) and the shaft hole (1343).

[0137]

[0144] A portion (131s) of the periphery of the first press portion (131) adjacent to the bar slot (1341, 1342) may extend parallel to the bar slot (1341, 1342).

[0145] The frame (130) may be positioned between the bar slot (1341, 1342) and the first press part (131) or the second press part (132) in the rotational direction of the supporter (200), and may include a fixing hole (1345, 1346) to which the bar (2171, 2172) is caught, and the first press part (131) and the second press part (132) may extend along the direction in which the fixing hole (1345, 1346) and the shaft hole (1343) are spaced apart from each other.
