[0028] For ease of explanation, the case where the lengths of the first long side LS1 and the second long side LS2 are greater than the lengths of the first short side SS1 and the second short side SS2 is shown and explained. However, it is also possible that the lengths of the first long side LS1 and the second long side LS2 are approximately the same as the lengths of the first short side SS1 and the second short side SS2.

[0029] The direction parallel to the long sides LS1 and LS2 of the display device 100 can be referred to as the first direction DR1 or the left-right direction LR. The direction parallel to the short sides SS1 and SS2 of the display device 100 can be referred to as the second direction DR2 or the up-down direction UD.

[0030] The direction perpendicular to the long sides LS1, LS2 and short sides SS1, SS2 of the display device 100 can be referred to as the third direction DR3 or the front-back direction FR. Here, the direction in which the image is displayed on the display panel 110 can be referred to as the front, and the direction opposite to the front can be referred to as the rear.

[0031] The following description uses an OLED (Organic Light Emitting Diode) display panel as an example to illustrate the display panel 110, but the display panel 110 that can be used in this invention is not limited to this.

[0032] The display panel 110 can form the front of the display device 100 and display an image forward. The display panel 110 can divide the image into a plurality of pixels and output the image in a matching manner according to 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 equivalent to red, green, or blue according to a control signal.

[0033] 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 mid-frame 130.

[0034] 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.

[0035] For example, the front skin 132 and the rear skin 133 can be galvanized steel sheets. As another example, the front skin 132 and the rear skin 133 can contain aluminum (Al).

[0036] For example, the thickness of the front skin 132 and the rear skin 133 can be 0.2 to 0.5 mm. As another example, the front skin 132 and the rear skin 133 formed of galvanized steel sheet can be 0.27 mm. As yet another example, the front skin 132 and the rear skin 133 containing aluminum can be 0.5 mm.

[0037] The front skin 132 and the rear skin 133 may face each other across the core 131 (described later). The core 131 may be located between the front skin 132 and the rear skin 133. The core 131 may contain fibers. The core 131 may be formed of a composite material. The core 131 may include main fibers and binder fibers. The binder fibers may be mixed between the main fibers.

[0038] The front skin 132 and / or the rear skin 133 can be bonded to the core 131 via a hot-melt layer process. A hot-melt sheet can be located between the front skin 132 and the core 131, and a hot-melt sheet can be located between the rear skin 133 and the core 131. The hot-melt sheet can be a film. For example, the hot-melt sheet can be a film of EVA, acrylic, polyurethane, etc., with a thickness of 50 micrometers or more. After the core 131 is positioned between the front skin 132 and the rear skin 133 using the hot-melt sheet, it can be rolled together at 190 degrees Celsius for at least 1 minute.

[0039] This can improve the bending and / or torsional rigidity of the display device.

[0040] Reference Figure 3 and 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 a roll-to-roll process.

[0041] Reference Figure 3As the pinch roll Ra, which drives the motor, rotates, the front skin 132 can be unwound from the front roll Da, the rear skin 133 can be unwound from the rear roll Db, and the core 131 can move via the feed roll Rd. Furthermore, the first adhesive 134a used to bond the front skin 132 to the core 131 can be unwound from the first roll Dc. Additionally, the second adhesive 134b used to bond the rear skin 133 to the core 131 can be unwound from the second roll Db. In this case, the front skin 132, the first adhesive 134a, the core 131, the second adhesive 134b, and the rear skin 133 are stacked in the above order and guided by the guide roll Rc towards the oven Ov. The adhesives 134a and 134b can be hot melt sheets 134a and 134b.

[0042] The first adhesive 134a and the second adhesive 134b can be melted in an oven Ov, while the front skin 132 and the rear skin 133 can be bonded to the core 131 respectively. For example, the melting point of the first adhesive 134a and the second adhesive 134b can be about 150°C, and the atmosphere temperature of the oven Ov can be about 200°C. For example, the peel force of the first adhesive 134a and the second adhesive 134b can be about 10 kgf or more.

[0043] The front skin 132, core 131, and rear skin 133, having passed through the oven Ov, are guided to the pressure roller Rb by the rotation of the clamping roller Ra and pressed against it. This further increases the bonding force between the front skin 132, core 131, and rear skin 133. The bonded front skin 132, core 131, and rear skin 133 can then be cut by the cutting machine Ct after passing through the clamping roller Ra, thereby producing a composite material panel 130 of specified dimensions.

[0044] Reference Figure 4 The pressure roller Rb or clamping roller Ra can contact the outer surfaces of the front skin 132 and the rear skin 133, respectively. If the pressure roller Rb or clamping roller Ra rotates, the composite panel 130 can move along the length direction of the core 131 (i.e., the left-right direction LR). At this time, the front skin 132 and the rear skin 133 can be sequentially joined from one end of the core 131 to the other end along the length direction of the core 131.

[0045] Furthermore, the front skin 132 and rear skin 133 of the composite material panel 130 can be formed flat. That is, by making the back of the rear skin 133, which forms the back of the display device 100, flat, it is easier to perform additional operations such as painting or attaching stickers to the back of the rear skin 133 for aesthetic purposes.

[0046] On the other hand, besides referring to Figure 3 andFigure 4 In addition to forming the front skin 132 and the rear skin 133 flat using the roll-to-roll process described above, the core 131, the front skin 132, and the rear skin 133 can also be joined together by sequentially stacking the front skin 132, the core 131, and the rear skin 133 and then joining them together.

The rear skin 133 of the receiving portion 137 can form a step D2 that increases in height from the rear skin 133 of the flat plate portion 130P. At this time, the height of the step D1 that decreases in height from the front skin 132 of the flat plate portion 130P to the front skin 132 of the receiving portion 137 can be greater than the height of the step D2 that increases in height from the rear skin 133 of the flat plate portion 130P to the rear skin 133 of the receiving portion 137. The thickness T1 of the flat plate portion 130P can be greater than the thickness T2 of the receiving portion 137.

[0051] When pressure is applied from the front skin 132 of the flat plate 130P towards the rear skin 133, the core 131 of the composite material panel 130 can absorb the external force. The magnitude of the external force applied to the front skin 132 of the flat plate 130P can be greater than the magnitude of the external force applied to the rear skin 133 of the flat plate 130P. The core 131 of the composite material panel 130 not only ensures rigidity but also absorbs impact.

[0052] The thickness T4 of the third outer portion 135c can be greater than the thickness T2 of the receiving portion 137. A step D2 can be formed that increases in height from the rear skin 133 of the third outer portion 135c to the rear skin 133 of the receiving portion 137.

The fourth node hole 224 can be formed by penetrating the composite material panel 130 at node M1 of the second horizontal lines 212, 232 and the second vertical lines 212, 232.

[0087] The fifth node hole 225 can be located at the corner C4 formed by the third horizontal lines 213, 233 and the first vertical lines 214, 234.

The sixth node hole 226 can be formed by penetrating the composite material panel 130 at the corner C3 of the third horizontal lines 213, 233 and the second vertical lines 212, 232.

[0089] This not only improves the bending and / or torsional rigidity of the composite panel 130, but also improves the flatness of the display panel 110 bonded to the composite panel 130.

[0090] Reference Figure 19 The size of the sixth node hole 226 can be greater than the width of the third horizontal lines 213, 233 and / or the second vertical lines 215, 235. For example, when the sixth node hole 226 is quadrilateral, the widths A and B of the sixth node hole 226 can be greater than the width W of the third horizontal lines 213, 233 and / or the second vertical lines 215, 235. As another example, when the sixth node hole 226 is circular, the diameter of the sixth node hole 226 can be greater than the width of the third horizontal lines 213, 233 and / or the second vertical lines 215, 235. This description of the sixth node hole 226 can be applied to the first node hole 221, the second node hole 222, and / or the fifth node hole 225.

[0091] Reference Figure 20 The size of the fourth node hole 224 can be greater than the width of the second horizontal lines 212, 232 and / or the second vertical lines 215, 235. For example, when the fourth node hole 224 is quadrilateral, the widths A and B of the fourth node hole 224 can be greater than the widths of the second horizontal lines 212, 232 and / or the second vertical lines 215, 235.

[0092] Reference Figure 21 The front inner line 210 can be formed in the composite material panel 130 by the compression of the core 131 and the indentation of the front skin 132. The rear inner line 230 can be formed in the composite material panel 130 by the compression of the core 131 and the indentation of the rear skin 133.

[0093] The front inner line 210 and the rear inner line 230 can be symmetrical with respect to the core 131. For example, the width W of the front inner line 210 can be substantially the same as the width W of the rear inner line 230. As another example, the depth D10 of the front inner line 210 can be substantially the same as the depth D11 of the rear inner line 230.

[0094] A compressed area PA with core 131 compressed can be formed between the front inner line 210 and the rear inner line 230. The density of core 131 in the compressed area PA can be greater than the density of core 131 in the uncompressed area.

[0095] This can improve the flexural and / or torsional stiffness of the composite panel 130.

[0107] The display panel 110 can be bonded or fixed to the composite panel 130 by means of the adhesive member AD. Thus, the display panel 110 can be fixed flatly to the composite panel 130.

[0108] Reference Figure 23 The heat sink 300 can be located on the front skin 132 of the composite panel 130. The heat sink 300 can be bonded to the flat portion 130P of the composite panel 130. The heat sink 300 can cover the front inner lines 211, 212, 213 and / or node holes 220 of the inner frame 210. For example, the heat sink 300 can be an aluminum sheet. The heat sink 300 can be bonded to the flat portion 130P of the composite panel 130. The heat sink 300 can be referred to as the front heat sink 300.

[0109] The first heat sink 310 can extend elongatedly along the first front horizontal line 211 and is bonded to the plate portion 130P while covering the first front horizontal line 211 and / or the node hole 220. The second heat sink 320 can extend elongatedly along the second front horizontal line 212 and is bonded to the plate portion 130P while covering the second front horizontal line 212 and / or the node hole 220. The third heat sink 330 can extend elongatedly along the third front horizontal line 213 and is bonded to the plate portion 130P while covering the third front horizontal line 213 and / or the node hole 220.

[0110] The fourth heat sink 340 may be located between the first front horizontal line 211 and the sixth adhesive member AD6. The fourth heat sink 340 may extend elongatedly along the first front horizontal line 211 and be adhesively bonded to the flat plate portion 130P. For example, the length of the fourth heat sink 340 may be less than the length of the first heat sink 310. The width of the fourth heat sink 340 may be greater than the width of the first heat sink 310.

[0111] Reference Figure 24 The heat sink 300 can be located between the display panel 110 and the composite panel 130. The heat sink 300 can contact the flat portion 130P of the composite panel 130. The heat sink 300 can cover the front inner lines 211, 212, and 213 of the inner frame 210. The display panel 110 can be spaced apart from the heat sink 300. The gap H1 between the display panel 110 and the composite panel 130 can be connected to the adhesive member AD (see reference). Figure 22 The thickness corresponds to the thickness of the adhesive component AD. For example, the thickness of the adhesive component AD can be the spacing between the composite panel 130 and the display panel 110.

[0112] Reference Figure 23 The fourth heat sink 340 is located between the front skin 132 of the flat plate portion 130P of the composite material panel 130 and the display panel 110, so that the distance H3 between the display panel 110 and the heat sink 300 can be smaller than the distance H1 between the display panel 110 and the composite material panel 130. This improves the heat conduction and diffusion between the display panel 110 and the composite material panel 130.

[0113] The heat generated in the display panel 110 can be released to the composite panel 130. The heat released from the display panel 110 can be transferred to the front skin 132 of the composite panel 130. Due to the recess of the front skin 132 of the inner front lines 211, 212, 213 of the inner frame 210, the diffusion of heat released from the display panel 110 may be uneven.

[0114] The core 131 of the composite panel 130 can block the passage of heat generated in the display panel 110. The heat generated in the display panel 110 needs to diffuse uniformly in front of the composite panel 130; heat condensation can degrade the performance of the display panel 110. The heat generated in the display panel 110 can be condensed by the front inner lines 211, 212, and 213 of the inner frame 210. The distance H2 between the display panel 110 and the front skin 132 of the front inner lines 211, 212, and 213 can be greater than the distance H1 between the display panel 110 and the front skin 132 of the composite panel 130. This can be a reason for the condensation of heat generated in the display panel 110.

[0115] The heat generated in the display panel 110 can be dissipated to the heat sink 300. The heat sink 300 can conduct and diffuse the heat generated in the display panel 110. The heat sink 300 can transfer the heat generated in the display panel 110 to the front skin 132 of the composite material panel 130. This improves the heat dissipation effect.

[0116] Reference Figure 25 A heat sink 300 may be located between the display panel 110 and the composite panel 130. The heat sink 300 may contact the flat portion 130P of the composite panel 130. The heat sink 300 may cover the front inner lines 211, 212, 213 and the node holes 220 of the inner frame 210. The display panel 110 may be spaced apart from the heat sink 300. The gap H1 between the display panel 110 and the composite panel 130 may be connected to the adhesive member AD (see reference). Figure 22 The thickness corresponds to the thickness of the adhesive component AD. For example, the thickness of the adhesive component AD can be the spacing between the composite panel 130 and the display panel 110.

[0117] Reference Figure 23The first heat sink 310, the second heat sink 320, and / or the third heat sink 330 are located between the front skin 132 of the flat plate portion 130P of the composite material panel 130 and the display panel 110, so that the distance H3 between the display panel 110 and the heat sink 300 can be smaller than the distance H1 between the display panel 110 and the composite material panel 130. This improves heat conduction and diffusion between the display panel 110 and the composite material panel 130.

[0118] The heat generated in the display panel 110 can be released to the composite material panel 130. The heat released from the display panel 110 can be transferred to the front skin 132 of the composite material panel 130. Due to the recess of the front skin 132 of the inner frame 210's front inner lines 211, 212, 213, and the formation of the node hole 220 through the front skin 132, rear skin 133, and core 131, the diffusion of heat released from the display panel 110 may be uneven.

[0119] The heat emitted from the display panel 110 needs to be evenly diffused in front of the composite material panel 130. Heat condensation or heat inflow can degrade the performance of the display panel 110. Due to the front inner lines 211, 212, and 213 of the inner frame 210, the heat generated in the display panel 110 can be condensed. Due to the node holes 220, heat can flow into the display panel 110. The distance H2 between the display panel 110 and the front skin 132 of the front inner lines 211, 212, and 213 can be greater than the distance H1 between the display panel 110 and the front skin 132 of the composite material panel 130. This can be a cause of heat condensation in the display panel 110.

[0120] The heat generated in the display panel 110 can be dissipated to the heat sink 300. The heat sink 300 can conduct and diffuse the heat generated in the display panel 110. The heat sink 300 can transfer the heat generated in the display panel 110 to the front skin 132 of the composite material panel 130. This improves the heat dissipation effect.

[0121] Heat flowing in from the rear of the composite panel 130 through the node holes 220 can be conducted and diffused through the heat sink 300. The heat sink 300 can prevent the heat flowing in through the node holes 220 from being directly transferred to the display panel 110.

[0122] Reference Figure 26 and Figure 27The heat sink 390 can be located on the back of the composite panel 130, between the composite panel 130 and the PCB board 150. The heat sink 390 can be referred to as the rear heat sink 390. For example, the rear heat sink 390 can be a graphite sheet. The power supply unit PS can be located behind and mounted on the PCB board 150. The rear heat sink 390 can be aligned with the position of the power supply unit PS. For example, the area of ​​the rear heat sink 390 can correspond to the area of ​​the power supply unit PS.

[0123] A front heat sink 300 may be located between the display panel 110 and the composite panel 130. The front heat sink 300 may contact the flat portion 130P of the composite panel 130. The front heat sink 300 may cover the front inner lines 211, 212, and 213 of the inner frame 210. The display panel 110 may be spaced apart from the front heat sink 300. The gap H1 between the display panel 110 and the composite panel 130 may be connected to the adhesive member AD (see reference). Figure 22 The thickness corresponds to ).

[0124] The heat generated in the display panel 110 can be released to the composite panel 130. The heat released from the display panel 110 can be transferred to the front skin 132 of the composite panel 130. Due to the recess of the front skin 132 of the inner front lines 211, 212, 213 of the inner frame 210, the diffusion of heat released from the display panel 110 may be uneven.

[0125] The core 131 of the composite panel 130 can block the passage of heat generated in the display panel 110. The heat generated in the display panel 110 needs to diffuse uniformly in front of the composite panel 130; heat condensation can degrade the performance of the display panel 110. The heat generated in the display panel 110 can be condensed by the front inner lines 211, 212, and 213 of the inner frame 210. The distance H2 between the display panel 110 and the front skin 132 of the front inner lines 211, 212, and 213 can be greater than the distance H1 between the display panel 110 and the front skin 132 of the composite panel 130. This can be a reason for the condensation of heat generated in the display panel 110.

[0126] The heat generated in the display panel 110 can be dissipated to the front heat sink 300. The front heat sink 300 can conduct and diffuse the heat generated in the display panel 110. The front heat sink 300 can transfer the heat generated in the display panel 110 to the front skin 132 of the composite material panel 130. This improves the heat dissipation effect.

[0127] The rear heat sink 390 can contact the rear skin 133 of the composite panel 130 and the PCB board 150. Alternatively, the rear heat sink 390 can be bonded to the rear skin 133 of the composite panel 130, forming a gap with the PCB board 150. The heat generated in the power supply unit PS may be high. The heat generated in the power supply unit PS can be transferred to the rear skin 133 of the composite panel 130 through the PCB board 150. The rear heat sink 390 can diffuse the heat transferred through the PCB board 150. The rear heat sink 390 can minimize the heat transfer to the rear skin 133 of the composite panel 130 and diffuse the heat throughout the entire rear heat sink 390. The core 131 of the composite panel 130 can block the heat transferred to the rear skin 133 through the rear heat sink 390. Thus, heat dissipation and heat insulation of the display panel 110 can be effectively performed.

[0128] Reference Figure 28 The front heat sink 300 can be located between the display panel 110 and the composite panel 130. The front heat sink 300 can contact the flat portion 130P of the composite panel 130. The front heat sink 300 can cover the front inner lines 211, 212, 213 and the node holes 220 of the inner frame 210. The display panel 110 can be spaced apart from the front heat sink 300. The gap H1 between the display panel 110 and the composite panel 130 can be connected to the adhesive member AD (see reference). Figure 22 The thickness corresponds to the thickness of the adhesive component AD. For example, the thickness of the adhesive component AD can be the interval between the composite panel 130 and the display panel 110.

[0129] Reference Figure 23 The first front heat sink 310, the second front heat sink 320, and / or the third front heat sink 330 are located between the front skin 132 of the flat portion 130P of the composite material panel 130 and the display panel 110, so that the distance H3 between the display panel 110 and the front heat sink 300 can be smaller than the distance H1 between the display panel 110 and the composite material panel 130. This improves heat conduction and diffusion between the display panel 110 and the composite material panel 130.

[0130] The heat generated in the display panel 110 can be released to the composite material panel 130. The heat released from the display panel 110 can be transferred to the front skin 132 of the composite material panel 130. Due to the recess of the front skin 132 of the inner frame 210's front inner lines 211, 212, 213, and the formation of the node hole 220 through the front skin 132, rear skin 133, and core 131, the diffusion of heat released from the display panel 110 may be uneven.

[0131] The heat emitted from the display panel 110 needs to be evenly diffused in front of the composite material panel 130. Heat condensation or heat inflow can degrade the performance of the display panel 110. Due to the front inner lines 211, 212, and 213 of the inner frame 210, the heat generated in the display panel 110 can be condensed. Due to the node holes 220, heat can flow into the display panel 110. The distance H2 between the display panel 110 and the front skin 132 of the front inner lines 211, 212, and 213 can be greater than the distance H1 between the display panel 110 and the front skin 132 of the composite material panel 130. This can be a cause of heat condensation in the display panel 110.

[0132] The heat generated in the display panel 110 can be dissipated to the front heat sink 300. The front heat sink 300 can conduct and diffuse the heat generated in the display panel 110. The front heat sink 300 can transfer the heat generated in the display panel 110 to the front skin 132 of the composite material panel 130. This improves the heat dissipation effect.

[0133] The rear heat sink 390 can contact the rear skin 133 of the composite panel 130 and the PCB board 150. Alternatively, the rear heat sink 390 can be bonded to the rear skin 133 of the composite panel 130, forming a gap with the PCB board 150. The heat generated in the power supply unit PS may be high temperature. The heat generated in the power supply unit PS can be transferred to the rear skin 133 of the composite panel 130 through the PCB board 150. The rear heat sink 390 can diffuse the heat transferred through the PCB board 150. The rear heat sink 390 can minimize or block heat transfer to the rear skin 133 of the composite panel 130 and diffuse heat throughout the entire rear heat sink 390.

[0134] Heat flowing in from the rear of the composite panel 130 through the node holes 220 can be conducted and diffused via the rear heat sink 390. The front heat sink 300 and / or the rear heat sink 390 can prevent the heat flowing in through the node holes 220 from being directly transferred to the display panel 110.

[0135] Therefore, heat dissipation and heat insulation of the display panel 110 can be effectively performed.
