Furthermore, the location where the first long side LS1, the second long side LS2, the first short side SS1, and the second short side SS2 intersect each other can be referred to as the corner.

[0031] The intersection of the first short side SS1 and the first long side LS1 can be the first corner C1.

The intersection of the second short side SS2 and the second long side LS2 can be the third corner C3. The intersection of the second short side SS2 and the first long side LS1 can be the fourth corner C4.

[0032] Hereinafter, the display panel 110 will be described using an organic light-emitting diode (OLED) display panel as an example, but the display panel 110 applicable to the present invention is not limited thereto.

[0033] The display panel 110 forms the front of the display device 100 and can display images forward. The display panel 110 outputs an image by dividing the image into a plurality of pixels and matching the color, brightness, and saturation of each pixel. The display panel 110 can be divided into an active area for displaying the image and a de-active area for not displaying the image. The display panel 110 can generate light corresponding to red, green, or blue according to a control signal.

[0034] Reference Figure 2 The material complexed panel 130 may include a core 131, a front skin 132, and a rear skin 133. The core 131, front skin 132, and rear skin 133 may be bonded together. The material complexed panel 130 may be referred to as a fiber complexed panel 130, a fiber complexed plate 130, a composite material plate 130, or a frame 130.

[0035] The front skin 132 can form the front side of the composite panel 130. The rear skin 133 can form the back side of the composite panel 130. The front skin 132 and the rear skin 133 can be made of metal. For example, the front skin 132 and the rear skin 133 can be made of aluminum (Al). For example, the thickness of the front skin 132 and the rear skin 133 can be about 0.5 mm. The front skin 132 and the rear skin 133 can face each other relative to the core 131.

[0036] Core 131 may be located between front skin 132 and rear skin 133. Core 131 may include fibers. Core 131 may be formed of composite materials. Core 131 may include main fibers and binder fibers. The binder fibers may be mixed between the main fibers.

[0037] A hot-melt sheet may be located between the front skin 132 and the core 131. Additionally, a hot-melt sheet may be located between the rear skin 133 and the core 131. The hot-melt sheet may be a film. For example, the hot-melt sheet may be a film of EVA, acrylic resin, polyurethane, etc., with a thickness of 50 micrometers or more. The core 131 and the hot-melt sheet may be bonded to the front skin 132 and the rear skin 133 at a high temperature (e.g., approximately 190–200°C) for a period of more than one minute.

[0038] Therefore, the composite material panel 130 can improve the bending stiffness and / or torsional stiffness of the display device.

[0039] Reference Figure 3 and Figure 4 The composite panel 130 can be manufactured by using a plurality of rollers to press the front skin 132 and the rear skin 133 onto the core 131, a process that can be called an R2R (Roll-to-Roll) process.

[0040] Reference Figure 3 As the extrusion roller Ra, which functions as a drive motor, rotates, the front skin 132 can be detached from the front roller Da, the rear skin 133 can be detached from the rear roller Db, and the core 131 can move via the feed roller Rd. Furthermore, the first adhesive 134a used to bond the front skin 132 to the core 131 can be detached from the first roller Dc. Additionally, the second adhesive 134b used to bond the rear skin 133 to the core 131 can be detached from the second roller Db. In this configuration, the front skin 132, the first adhesive 134a, the core 131, the second adhesive 134b, and the rear skin 133 can be stacked in the aforementioned order and guided by the guide roller Rc towards the oven Ov. The adhesives 134a and 134b can be hot-melt sheets 134a and 134b.

[0041] The first adhesive 134a and the second adhesive 134b can be melted within an oven Ov, and the front skin 132 and the rear skin 133 can be bonded to the core 131. For example, the melting point of the first adhesive 134a and the second adhesive 134b can be about 150°C, and the ambient temperature in the oven Ov can be about 200°C. For example, the peel-off force of the first adhesive 134a and the second adhesive 134b can be about 10 kgf or more.

[0042] The front skin 132, core 131, and rear skin 133, having passed through the oven Ov, are guided to the pressing roller Rb by the rotation of the extrusion roller Ra, and can be pressed by the pressing roller Rb. This further increases the bonding force between the front skin 132, core 131, and rear skin 133. After passing through the extrusion roller Ra, the bonded front skin 132, core 131, and rear skin 133 can be cut by the cutting tool Ct to manufacture a composite material panel 130 of a certain size.

[0043] Reference Figure 4The pressing roller Rb or the extrusion roller Ra can contact the outer surfaces of the respective front skin 132 and rear skin 133. If the pressing roller Rb or the extrusion roller Ra rotates, the composite panel 130 can move along the length direction of the core 131. At this time, along the length direction of the core 131, the front skin 132 and the rear skin 133 can be sequentially joined from one end of the core 131 to the other end.

[0044] Furthermore, the front skin 132 and rear skin 133 of the composite material panel 130 can be formed flat. That is, since the back of the rear skin 133, which forms the back of the display device 100, is formed flat, it is easier to perform additional operations such as painting or applying stickers to the back of the rear skin 133 for aesthetic purposes. Alternatively, the flat rear skin 133 itself can also form the back of the display device 100.

[0045] On the other hand, besides referencing Figure 3 and Figure 4 In addition to the aforementioned R2R process, composite material panel 130 can also be manufactured by stacking the front skin 132, core 131 and rear skin 133 in sequence and then bonding them together.

[0046] Reference Figure 5 and Figure 6 The display panel 110 can be bonded to the front skin 132 of the composite panel 130 using an adhesive member AD, such as double-sided adhesive tape. For example, the thickness of the adhesive member AD can be 0.2 to 0.4 mm.

[0047] The heat sink HA can be located in the air gap between the display panel 110 and the composite panel 130, and can be attached to the front skin 132. For example, multiple heat sinks HA can be attached to the front skin 132. The heat sink HA can be made of metal. For example, the heat sink HA can be a plate or adhesive tape made of aluminum (Al). For example, the thickness of the heat sink HA can be 0.15 to 0.25 mm, and the air gap between the display panel 110 and the composite panel 130 can be 0.04 to 0.1 mm.

[0048] Therefore, the air gap between the display panel 110 and the composite material panel 130 can be reduced by the heat sink HA, thereby effectively removing the heat generated in the display panel 110.

[0049] Reference Figure 7 and Figure 8The composite panel 130 may include a flat plate portion 130P, a receiving portion 137, and an outer contour portion 135. The front skin 132 of the composite panel 130 may define the front of each flat plate portion 130P, receiving portion 137, and outer contour portion 135.

[0050] An outer contour portion 135 may be formed around the periphery of the flat plate portion 130P. A first outer contour portion 135a may be formed along the upper edge of the flat plate portion 130P. A second outer contour portion 135b may be formed along the lower edge of the flat plate portion 130P. A third outer contour portion 135c may be formed along the left side of the flat plate portion 130P. A fourth outer contour portion 135d may be formed along the right side of the flat plate portion 130P. The thickness T4 of the outer contour portion 135 may be less than the thickness T1 of the flat plate portion 130P.

[0051] The receiving portion 137 can be formed by stamping rearward from the flat plate portion 130P. The receiving portion 137 can be located between the lower edge of the flat plate portion 130P and the second outer contour portion 135b. The receiving portion 137 can form a step relative to the flat plate portion 130P and the second outer contour portion 135b. The thickness T3 of the receiving portion 137 can be greater than the thickness T4 of the outer contour portion 135.

[0052] The cable hole 136 can be formed by passing through the receiving portion 137. For example, a plurality of cable holes 136a, 136b can be adjacent to each other.

[0053] Reference Figure 9 Cable 113 can extend from the bottom of display panel 110 between display panel 110 and composite panel 130.

[0054] S-PCB (Source PCB) 115 may be located in the receiving portion 137 of the composite panel 130. S-PCB 115 may be electrically connected to cable 113.

[0055] The side frame 140 may extend along the periphery of the display panel 110. The horizontal portion 140H may cover the side of the display panel 110 and the side of the composite panel 130. The vertical portion 140V may be located between the display panel 110 and the composite panel 130. The side frame 140 may be referred to as a guide panel or an intermediate housing.

[0056] Reference Figure 10 and Figure 11 The bonding plate 150 can be located behind the composite panel 130. The horizontal portion 152, the vertical portion 153, and the dome 154 of the bonding plate 150 can be formed by stamping from the front to the rear of the main body 151 of the bonding plate 150.

[0057] The main body FA of the fastening member FP can penetrate the recess 130R, and the head FH of the fastening member FP can be locked onto the front of the recess 130R. The recess 130R can be formed to be recessed rearward from the flat plate 130P. The main body FA of the fastening member FP can be bolted to the connecting plate 150.

[0058] Therefore, the bonding plate 150 can be bonded to the composite material panel 130. The bonding plate 150 can be referred to as PCB board 150. A plurality of PCBs B1, B2, B3 can be mounted on the back of the bonding plate 150.

[0059] The rear cover 170 can cover the rear of the connecting plate 150. The rear cover 170 can be attached to the connecting plate 150 by means of bolts or the like. A portion 133A of the rear skin 133 of the composite panel 130 may not be covered by the rear cover 170.

[0060] Reference Figure 12 and Figure 13 The vertical rod 160 can extend long in the vertical direction. The vertical rod 160 can be located behind the composite panel 130. The first vertical rod 161 and the second vertical rod 162 can be spaced apart from each other in the horizontal direction. The first vertical rod 161 and the second vertical rod 162 can have the same shape.

[0061] The main body FA of the fastening member FB can penetrate the recess 130R, and the head FH of the fastening member FB can be locked onto the front of the recess 130R. The recess 130R can be formed to be recessed rearward from the flat plate 130P. The main body FA of the fastening member FB can be bolted to the vertical rod 160.

[0062] Thus, the first vertical bar 161 and the second vertical bar 162 can be attached to the composite material panel 130.

[0063] On the other hand, a plurality of first fastening portions 161v can be formed on the first vertical rod 161 and can be spaced apart from each other along the length of the first vertical rod 161. A plurality of second fastening portions 162v can be formed on the second vertical rod 162 and can be spaced apart from each other along the length of the second vertical rod 162. The plurality of first fastening portions 161v and the plurality of second fastening portions 162v can be aligned with a plurality of fastening holes 170v formed on the rear cover 170. The spacing between the plurality of fastening holes 170v can conform to VESA (Video Electronics Standards Association) standards.

[0064] Therefore, the support or bracket for the display device can be bolted to the plurality of fastening parts 161v and 162v using the plurality of fastening holes 170v.

[0065] Reference Figure 12 and Figure 14 The PCB (Printed Circuit Board) B can be located behind the composite panel 130. For example, multiple PCBs B1, B2, and B3 can be spaced apart from each other. The power supply board B1 can supply power to the various structural components of the display device. The T-CON board (Timing Controller Board) B2 can provide image signals to the display panel 110. The main board B3 can control the various structural components of the display device.

[0066] The fixing part PN can protrude rearward from the back of the composite panel 130. For example, the recess 130N can be formed by recessing forward from the back of the composite panel 130, and the fixing part PN can protrude rearward from the recess 130N. For example, the fixing part PN can be a pemnut. Fastening components such as bolts can penetrate the PCB B and be fastened to the fixing part PN.

[0067] Therefore, PCB B can be bonded to composite panel 130. In other words, PCB B can be bonded to composite panel 130 without PCB board 150 (see reference). Figure 10 and Figure 11 ).

[0068] Reference Figure 12 and Figure 15 The back cover 170 may have a box shape that is generally open to the front. The rear portion 171 may form the back of the back cover 170. The top portion 172a may extend along the upper edge of the rear portion 171 and may intersect with the rear portion 171. The bottom portion 172b may extend along the lower edge of the rear portion 171 and may intersect with the rear portion 171. The first side portion 172c may extend along the left side of the rear portion 171 and may intersect with the rear portion 171. The second side portion 172d may extend along the right side of the rear portion 171 and may intersect with the rear portion 171.

[0069] The locking portion 173 can protrude downward from the inside of the top portion 172a. A plurality of locking portions 173a, 173b, and 173c can be spaced apart from each other along the top portion 172a. The plurality of locking portions 173a, 173b, and 173c can have the same shape as each other. The locking portion 173 can be referred to as a latch.

[0070] Reference Figure 16 and Figure 17, the block 1731 of the locking portion 173 can extend in a direction crossing the top portion 172a, and the upper end of the block 1731 can be fixed to the inside of the top portion 172a. For example, the block 1731 can be formed integrally with the top portion 172a (one body).

[0071] Ribs 1735, 1736 can connect the back surface of the block 1731 and the inside of the top portion 172a. The ribs 1735, 1736 can have a triangular cross-section, and the height h10 of the ribs 1735, 1736 can be greater than or equal to the thickness t10 of the block 1731. The first rib 1735 can be adjacent to the left side of the block 1731, and the second rib 1736 can be adjacent to the right side of the block 1731. For example, the ribs 1735, 1736 can be formed integrally with the block 1731 and the top portion 172a (one body). Thus, the ribs 1735, 1736 can improve the rigidity of the block 1731.

[0072] The groove 1734 can be formed by being recessed upward from the lower side of the block 1731. The first part 1732 of the block 1731 can face the second part 1733 of the block 1731 with respect to the groove 1734, and the first part 1732 and the second part 1733 can form the lower side of the block 1731. For example, the lower side of the block 1731 can form a certain angle θ1 with respect to a virtual line parallel to the front-rear direction.

[0073] The first guiding surface 1734a, the second guiding surface 1734b, and the placement surface 1734c can define the boundary of the groove 1734. The first guiding surface 1734a and the second guiding surface 1734b can define the lower part of the boundary of the groove 1734, and the placement surface 1734c can define the upper part of the boundary of the groove 1734.

[0074] The first guiding surface 1734a can form a second angle θ2 with respect to a virtual line parallel to the width direction of the groove 1734. The second guiding surface 1734b can face the first guiding surface 1734a with respect to the groove 1734, and can form a third angle θ3 with respect to a virtual line parallel to the width direction of the groove 1734. For example, the second angle θ2 and the third angle θ3 can be the same. In addition, the interval between the first guiding surface 1734a and the second guiding surface 1734c can gradually increase as approaching the lower part from the upper part of the groove 1734 (refer to Figure 17 g11 < g10). The guiding surfaces 1734a, 1734b can be called chamfers.

[0075] The mounting surface 1734c can connect the first guide surface 1734a and the second guide surface 1734b. The mounting surface 1734c can be an upwardly convex curved surface. The mounting surface 1734c can define the minimum width of the groove 1734.

[0076] Reference Figure 18 and Figure 19 The top pin 130T can protrude rearward from the back of the composite panel 130. For example, the top pin 130T can be a press-fit nut provided on a portion 130N1 of the composite panel 130.

[0077] Furthermore, the top pin 130T may include a head 130T1 and a body 130T2. The body 130T2 can connect the composite material panel 130 and the head 130T1. The radius r21 of the head 130T1 may be larger than the radius r22 of the body 130T2. That is, an undercut may be formed between the head 130T1 and the body 130T2. In addition, the periphery of the head 130T1 may be arc-shaped.

[0078] Additionally, the top pin 130T may be adjacent to the inside of the top portion 172a of the rear cover 170. For example, a plurality of top pins 130T (see reference). Figure 12 The top pins 130T can be spaced apart from each other along the top portion 172a. The plurality of top pins 130T can engage with the plurality of locking portions 173 (see reference). Figure 15 Alignment.

[0079] The front surface of block 1731 can be formed flat, allowing the locking portion 173 to move smoothly on the rear skin 133 of the composite panel 130. Corresponding to the movement of the locking portion 173, the top pin 130T can be easily inserted into the groove 1734 of the locking portion 173 along the guide surfaces 1734a, 1734b. Furthermore, as mentioned above, since the periphery of the head 130T1 is arc-shaped, the top pin 130T can be inserted into the groove 1734 more easily.

[0080] Furthermore, the mounting surface 1734c can be mounted on the main body 130T2, and the back of the block 1731 can be locked onto the head 130T1. That is, the radius of curvature r10 of the mounting surface 1734c (refer to...) Figure 17 The radius r22 of the main body 130T2 can be greater than or equal to that of the main body 130T2, and the radius of curvature r10 of the mounting surface 1734c can be less than that of the radius r21 of the head 130T1.

[0081] Therefore, the back cover 170 can be attached to the composite panel 130 using the locking portion 173. In other words, the back cover 170 can be attached to the composite panel 130 without the need for the PCB board 150 (see reference). Figure 10 and Figure 11 ).

[0082] Reference Figure 20 and Figure 21 Side pin 130S can protrude rearward from the back of composite panel 130. For example, side pin 130S can be a press-fit nut provided on a portion 130N2 of composite panel 130.

[0083] Furthermore, the side pin 130S may include a head 130S1 and a body 130S2. The body 130S2 may connect the composite panel 130 and the head 130S1. The radius r31 of the head 130S1 may be larger than the radius r32 of the body 130S2. That is, an undercut may be formed between the head 130S1 and the body 130S2. In addition, the periphery of the head 130S1 may be arc-shaped.

[0084] A portion of the plurality of side pins 130S may be adjacent to the inside of the first side portion 172c of the rear cover 170 (see reference). Figure 12 The remainder of the plurality of side pins 130S may be adjacent to the inside of the second side portion 172d of the rear cover 170 (see reference). Figure 12 ).

[0085] The retainer 174 can protrude forward from the inside of the rear portion 171 of the rear cover 170. The retainer 174 can be aligned with the side pin 130S. A portion of the plurality of retainers 174 can be aligned with the side pin 130S adjacent to the inside of the first side portion 172c. The remaining portions of the plurality of retainers 174 can be aligned with the side pin 130S adjacent to the inside of the second side portion 172d.

[0086] Furthermore, the retainer 174 may include a protrusion 1741 and a grab 1742. The protrusion 1741 may protrude forward from the inside of the rear portion 171. The grab 1742 may be located between the protrusion 1741 and the side pin 130S, and may be fixed to the protrusion 1741.

[0087] The gripping part 1742 may include a first part 1742a, a second part 1742b, and a third part 1742c. The first part 1742a may be fixed to the front end of the protrusion 1741. The third part 1742c may be located in front of the first part 1742a, and the second part 1742b may connect the first part 1742a and the third part 1742c. Furthermore, a plurality of ribs (not shown) may connect the first part 1742a and the third part 1742c. The third part 1742c may be elastic.

[0088] The receiving portion 1742h can be formed by recessing rearward from the front end of the third portion 1742c. The first portion 1742d of the third portion 1742c can face the second portion 1742f of the third portion 1742c relative to the receiving portion 1742h, and the first portion 1742d and the second portion 1742f can form the front end of the third portion 1742.

[0089] The front end of the first portion 1742d can form a second angle θ20 relative to a virtual line parallel to the width direction of the receiving portion 1742h. The front end of the second portion 1742f can form a third angle θ30 relative to a virtual line parallel to the width direction of the receiving portion 1742h. For example, the second angle θ20 and the third angle θ30 can be the same. Furthermore, the distance between the front ends of the first portion 1742d and the second portion 1742f can gradually increase as it moves from the rear to the front. The first portion 1742d and the second portion 1742f can be referred to as a chamfer.

[0090] The first protrusion 1742e can protrude from the inside of the first portion 1742d toward the second portion 1742f. The second protrusion 1742g can protrude from the inside of the second portion 1742f toward the first protrusion 1742e. The receiving portion 1742h can be located behind the first protrusion 1742e and the second protrusion 1742g, and can generally have a square bracket shape. The gap g20 between the first protrusion 1742e and the second protrusion 1742g can be smaller than the width g21 of the receiving portion 1742h. That is, an undercut can be formed between the protrusions 1742e, 1742g and the receiving portion 1742h.

[0091] Corresponding to the movement of the rear cover 170 and the retainer 174 toward the side pin 130S, the side pin 130S can be easily inserted into the receiving portion 1742h of the gripping portion 1742 along the front end of the third portion 1742c. Furthermore, as mentioned above, since the periphery of the head 130S1 is arc-shaped, the side pin 130S can be inserted into the receiving portion 1742h more easily.

[0092] At this time, the gap g20 between the first protrusion 1742e and the second protrusion 1742g can be opened by the head 130S1, and can be narrowed again if the head 130S1 is inserted into the receiving portion 1742h. The first protrusion 1742e and the second protrusion 1742g can be locked in the head 130S1 inserted into the receiving portion 1742h. That is, twice the radius r31 of the head 130S1 can be greater than the gap g20 between the first protrusion 1742e and the second protrusion 1742g, and twice the radius r31 of the head 130S1 can be less than or equal to the width g21 of the receiving portion 1742h.

[0093] Therefore, the back cover 170 can be attached to the composite panel 130 using the retainer 174. In other words, the back cover 170 can be attached to the composite panel 130 without the need for the PCB board 150 (see reference). Figure 10 and Figure 11 ).

[0094] Reference Figure 22 The back cover 170 may be smaller than the composite panel 130. In this case, a portion 133A of the rear skin 133 of the composite panel 130 may not be covered by the back cover 170. Alternatively, the size of the back cover 170 may correspond to the size of the composite panel 130. For example, the back cover 170 may be made of metal or plastic.

[0095] On the other hand, a plurality of holes 170h for air passage can be formed on the top of the back cover 170.

[0096] Reference Figure 23 and Figure 24 The composite panel 130 may include a flat plate portion 130P and a receiving portion 137. The front skin 132 of the composite panel 130 may define the front surface of each flat plate portion 130P and receiving portion 137.

[0097] The receiving portion 137 can be formed by stamping rearward from the flat portion 130P. The receiving portion 137 can be adjacent to the lower edge 130D of the composite panel 130. The receiving portion 137 can form a step relative to the flat portion 130P. An S-PCB (not shown, SourcePCB: source printed circuit board) can be located in the receiving portion 137.

[0098] Cable holes 136 are formed by passing through receiving portion 137. For example, a plurality of cable holes 136a, 136b can be adjacent to each other. Cables (not shown) can be electrically connected to S-PCB 115 and can pass through cable holes 136 to T-CON board B2 (see reference). Figure 32 Electrical connection.

[0099] Reference Figure 25 The side frame 140 may include a first part 141, a second part 142, a third part 143, and a fourth part 144. The side frame 140 may be referred to as a guide panel or a middle housing.

[0100] The first vertical portion 141V of the first part 141 can form the upper edge of the side frame 140. The first horizontal portion 141H can intersect with the first vertical portion 141V, and the first ribs 141r1 and 141r2 can extend along the first vertical portion 141V on the first horizontal portion 141H.

[0101] The second vertical portion 142V of the second part 142 can form the lower edge of the side frame 140. The second horizontal portion 142H can intersect with the second vertical portion 142V.

[0102] The third vertical portion 143V of the third part 143 can form the left side of the side frame 140. The third horizontal portion 143H can intersect with the third vertical portion 143V, and the third ribs 143r1 and 143r2 can extend along the third vertical portion 143V on the third horizontal portion 143H.

[0103] Furthermore, the first connecting member CP1 can connect the left end of the first rib 141r2 and the upper end of the third rib 143r2. The second connecting member CP2 can connect the left end of the second horizontal portion 142H and the lower end of the third horizontal portion 143H. Thus, the third portion 143 can be combined with the first portion 141 and the second portion 142.

[0104] The fourth vertical portion 144V of the fourth part 144 can form the right side of the side frame 140. The fourth horizontal portion 144H can intersect with the fourth vertical portion 144V, and the fourth ribs 144r1 and 144r2 can extend along the fourth vertical portion 144V on the fourth horizontal portion 144H.

[0105] Furthermore, the third connecting member CP3 can connect the right end of the second horizontal portion 142H and the lower end of the fourth horizontal portion 144H. The fourth connecting member CP4 can connect the right end of the first rib 141r2 and the upper end of the fourth rib 144r2. Thus, the fourth part 144 can be combined with the first part 141 and the second part 142.

[0106] Reference Figure 26 and Figure 27 The composite material panel 130 can be located in front of the side frame 140 and can be combined with the side frame 140. The composite material panel 130 can cover the front of the aforementioned plurality of ribs 141r1, 141r2, 143r1, 143r2, 144r1, 144r2.

[0107] Reference Figure 28 The first corner fixing part FB1 can protrude rearward from the rear skin 133 of the composite material panel 130 and can be adjacent to the first connecting member CP1.

[0108] Reference Figure 29 The second corner fixing part FB2 can protrude rearward from the rear skin 133 of the composite material panel 130 and can be adjacent to the second connecting member CP2.

[0109] Reference Figure 30The third corner fixing part FB3 can protrude rearward from the rear skin 133 of the composite panel 130 and can be adjacent to the third connecting member CP3.

[0110] Reference Figure 31 The fourth corner fixing part FB4 can protrude rearward from the rear skin 133 of the composite panel 130 and can be adjacent to the fourth connecting member CP4.

[0111] On the other hand, the plurality of pins 130K, 130L, and 130R described later can penetrate the plurality of ribs 141r2, 143r2, and 144r2.

[0112] Reference Figure 32 and Figure 33 Multiple components B, BR, and SPK can be installed on the rear skin 133 of the composite panel 130.

[0113] The PCB (Printed Circuit Board) B can be located behind the composite panel 130. For example, multiple PCBs B1, B2, and B3 can be spaced apart from each other. The power supply board B1 can supply power to the various structural components of the display device. The T-CON board (Timing Controller Board) B2 can provide image signals to the display panel 110. The main board B3 can control the various structural components of the display device.

[0114] The fixing plate BR can be located behind the composite panel 130. The fixing plate BR can be located between the first part 141 of the side frame 140 and the T-CON plate B2.

The second loudspeaker SPKb can be adjacent to the second portion 142 and the fourth portion 144 of the side frame 140.

[0116] The fixing part PN can protrude rearward from the rear skin 133 of the composite panel 130. For example, the recess 130N can be formed by recessing forward from the rear skin 133, and the fixing part PN can protrude rearward from the recess 130N. For example, the fixing part PN can be a press-fit nut. Fastening components such as bolts FN can pass through the PCB B, the fixing plate BR, or the speaker SPK and be fastened to the fixing part PN.

[0117] Therefore, the PCBB, the mounting plate BR, and the speaker SPK can be integrated into the composite panel 130. In other words, the PCBB, the mounting plate BR, and the speaker SPK can be integrated into the composite panel 130 without the need for the PCB 150 (see reference).Figure 10 and Figure 11 ).

[0118] Reference Figure 34 and Figure 35 The vertical rod 160 can extend long in the vertical direction. The vertical rod 160 can be located behind the composite panel 130. The first vertical rod 161 and the second vertical rod 162 can be spaced apart from each other in the horizontal direction. The first vertical rod 161 and the second vertical rod 162 can have the same shape.

[0119] The main body FA of the fastening member FB can penetrate the recess 130R, and the head FH of the fastening member FB can be locked onto the front of the recess 130R. The recess 130R is formed by recessing rearward from the flat plate 130P. The main body FA of the fastening member FB can be bolted to the vertical rod 160.

[0120] Thus, the first vertical bar 161 and the second vertical bar 162 can be attached to the composite material panel 130.

[0125] Furthermore, the second side pin 130R may include a head 130R1, a body 130R2, and a leg 130R3. The body 130R2 and the leg 130R3 can connect the recess 130M3 and the head 130R1. The radius r41 of the head 130R1 may be greater than the radius r42 of the body 130R2, and the radius r41 of the head 130R1 may be less than or equal to the radius r43 of the leg 130R3.

[0126] Additionally, the head 130R1 may include a central portion 130R1a, a rear portion 130R1b, and a front portion 130R1c. The central portion 130R1a can form the maximum radius r41 of the head 130R1. The rear portion 130R1b can be connected to the rear of the central portion 130R1a, and its radius can gradually decrease as it moves away from the central portion 130R1a. The front portion 130R1c can be connected to the front of the central portion 130R1a, and its radius can gradually decrease as it moves away from the central portion 130R1a. The rear portion 130R1b can be referred to as a chamfer, and the front portion 130R1c can be referred to as an undercut.

In addition, the top locking portion 170C1 can pass through the central portion 130K1a of the head 130K1 and lock at the front portion 130K1c.
