[0034] In the following, the display panel 110 is described by taking a display panel using an organic light emitting diode (OLED) as an example, but the display panel 110 applicable to the present invention is not limited thereto.

[0035] The display panel 110 may form the front side of the display device 100 and may display an image forward. The display panel 110 divides the image into a plurality of pixels and controls the color, brightness, and chromaticity of each pixel to output the image. The display panel 110 may be divided into an active area for displaying an image and a de-active area for not displaying an image. The display panel 110 may generate light corresponding to red, green, or blue according to a control signal.

[0036] Reference Figure 2 The composite material panel 130 may include a core 131, a front skin 132, and a rear skin 133. The core 131, the front skin 132, and the rear skin 133 may be combined with each other. The composite material panel 130 may be referred to as a fiber composite panel 130, a fiber composite plate 130, a composite material plate 130, or a frame 130.

[0037] The front surface layer 132 may form the front side of the composite material panel 130. The rear surface layer 133 may form the rear side of the composite material panel 130. The front surface layer 132 and the rear surface layer 133 may include a metal material. For example, the front surface layer 132 and the rear surface layer 133 may include an aluminum (Al) material. As another example, the front surface layer 132 and the rear surface layer 133 may be galvanized iron, galvanized steel sheet. For example, the thickness of the front surface layer 132 and the rear surface layer 133 may be about 0.5 mm. The front surface layer 132 and the rear surface layer 133 may be opposite to each other across the core 131.

[0038] The core 131 may be located between the front surface layer 132 and the back surface layer 133. The core 131 may include fibers. The core 131 may be formed of a composite material. The core 131 may include a main fiber and a binder fiber. The binder fiber may be mixed between the main fibers.

[0039] A hot-melt sheet may be located between the front surface layer 132 and the core 131. In addition, the hot-melt sheet may be located between the back surface layer 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, polyurethane, etc. having a thickness of 50 micrometers or more. The core 131 and the hot-melt sheet may be laminated at a high temperature (e.g., about 190 to 200° C.) on the front surface layer 132 and the back surface layer 133 for more than 1 minute.

[0040] Thus, the composite material panel 130 can improve the bending rigidity and / or torsional rigidity of the display device.

[0041] Reference Figure 3 and Figure 4 The composite panel 130 may be manufactured by pressing the front surface layer 132 and the rear surface layer 133 onto the core 131 using a plurality of rollers, and such a process may be referred to as an R2R (Roll-to-Roll) process.

[0042] Reference Figure 3 According to the rotation of the pinch roller Ra that performs the function of the driving motor, the front surface layer 132 can be unrolled from the front roll Da, the rear surface layer 133 can be unrolled from the rear roll Db, and the core 131 can be moved via the feed roller Rd. In addition, the first adhesive 134a for bonding the front surface layer 132 to the core 131 can be unrolled from the first roll Dc. In addition, the second adhesive 134b for bonding the rear surface layer 133 to the core 131 can be unrolled from the second roll Db. In this case, the front surface layer 132, the first adhesive 134a, the core 131, the second adhesive 134b and the rear surface layer 133 can be stacked in the above order and can be guided by the guide roller Rc to the direction of the oven Ov. The adhesives 134a, 134b can be hot melt sheets 134a, 134b.

[0043] The first adhesive 134a and the second adhesive 134b may be melted in the oven Ov, and the front surface layer 132 and the rear surface layer 133 may be combined with the core 131. For example, the melting point of the first adhesive 134a and the second adhesive 134b may be about 150° C., and the ambient temperature of the oven Ov may be about 200° C. For example, the peel-off force of the first adhesive 134a and the second adhesive 134b may be about 10 kgf or more.

[0044] The front surface layer 132, the core 131 and the rear surface layer 133 passing through the oven Ov can be guided to the pressing roller Rb as the pinch roller Ra rotates and are compressed by the pressing roller Rb. Thus, the bonding force between the front surface layer 132, the core 131 and the rear surface layer 133 can be further increased. After passing through the pinch roller Ra, the front surface layer 132, the core 131 and the rear surface layer 133 bonded to each other can be cut by the cutting machine Ct to be manufactured into a composite material panel 130 of a predetermined size.

[0045] Reference Figure 4 , the pressing roller Rb or the pinch roller Ra may contact the outer surface of each of the front skin layer 132 and the rear skin layer 133. If the pressing roller Rb or the pinch roller Ra rotates, the composite material panel 130 may move along the length direction of the core 131. At this time, the front skin layer 132 and the rear skin layer 133 may be sequentially combined from one end to the other end of the core 131 in the length direction of the core 131.

[0046] In addition, the front surface layer 132 and the rear surface layer 133 of the composite material panel 130 can be formed flat. That is, as the rear surface layer 133 forming the rear surface of the display device 100 is formed flat, additional operations such as painting or attaching a sheet of paper on the rear surface layer 133 for aesthetic appearance can be easily performed. In addition, the flat rear surface layer 133 can also form the rear surface of the display device 100 by itself.

[0047] On the other hand, in addition to referring to Figure 3 and Figure 4 In addition to the R2R process described above, the composite material panel 130 may be manufactured by a process in which the front surface layer 132 , the core 131 , and the rear surface layer 133 are sequentially stacked and then bonded to each other.

[0048] Reference Figure 5 The core 131 may include a main core 131a and a bonding core 131b. The main core 131a may include a first fiber made of PET (polyethylene terephthalate) and a second fiber made of LM (long material). For example, the ratio of the first fiber to the second fiber in the main core 131a may be 50% respectively. The bonding core 131b may include fibers made of acrylic material.

[0049] The front surface layer 132 may include aluminum (Al) or galvanized iron, and the front surface layer 132 may be combined with the adhesive core 131 b by a first hot melt adhesive 134 a .

[0050] The rear surface layer 133 may include aluminum (Al) or galvanized iron, and the rear surface layer 133 may be combined with the main core 131 a by a second hot melt adhesive 134 b .

[0051] The front surface layer 132 may be closer to the display panel 110 than the rear surface layer 133 (see Fig.16 ), the front surface layer 132 may be exposed to a relatively high temperature environment compared to the rear surface layer 133. That is, a temperature difference may occur between the front surface layer 132 and the rear surface layer 133. For example, the temperature difference between the front surface layer 132 and the rear surface layer 133 may be about 4°C.

[0052] At this time, the hot melt adhesive 134a, 134b can be formed into a multilayer structure of fiber material. The hot melt adhesive 134a, 134b can include a first layer 1341, a second layer 1342 and a third layer 1343. For example, the first layer 1341, the second layer 1342 and the third layer 1343 can include synthetic fiber materials. For example, the first layer 1341 can include nylon material, and the first layer 1341 can be located between the second layer 1342 and the third layer 1343. For example, the second layer 1342 and the third layer 1343 can include PU (polyurethane) material.

[0053] Therefore, under the effect of the tensile properties of each layer of the composite material panel 130 , the bending phenomenon of the composite material panel 130 under the effect of thermal deformation caused by the temperature difference between the front surface layer 132 and the rear surface layer 133 can be minimized.

[0054] Reference Figure 6 The composite panel 130 may include a flat plate portion 130P, an outer contour portion 135 and a receiving portion 137. The front surface layer 132 of the composite panel 130 may define the front of the flat plate portion 130P, the front of the outer contour portion 135 and the front of the receiving portion 137.

[0055] The outer profile 135 may be formed along the periphery of the flat plate portion 130P. The outer profile 135 may be formed by stamping from the flat plate portion 130P to the rear. The first outer profile 135a may be formed along the top edge of the flat plate portion 130P. The second outer profile 135b may be formed along the right side of the flat plate portion 130P. The third outer profile 135c may be formed along the bottom edge of the flat plate portion 130P. The fourth outer profile 135d may be formed along the left side of the flat plate portion 130P.

[0056] The receiving portion 137 may be formed between the flat plate portion 130P and the third outer profile portion 135c. The receiving portion 137 may be formed by stamping from the flat plate portion 130P and / or the third outer profile portion 135c toward the rear.

[0057] The cable hole 136 may be formed through the accommodation portion 137 in the front-rear direction. For example, the plurality of cable holes 136a, 136b may be adjacent to each other.

[0058] Reference Figure 7 The thickness T1 of the flat plate portion 130P may be greater than the thickness T2 of the receiving portion 137. The step D1 between the front surface layer 132 of the flat plate portion 130P and the front surface layer 132 of the receiving portion 137 may be greater than the step D2 between the rear surface layer 133 of the flat plate portion 130P and the rear surface layer 133 of the receiving portion 137.

[0059] The thickness T4 of the third outer profile portion 135c may be greater than the thickness T2 of the receiving portion 137. The step D2 between the rear surface layer 133 of the third outer profile portion 135c and the rear surface layer 133 of the receiving portion 137 may be equal to the step D2 between the rear surface layer 133 of the flat portion 130P and the rear surface layer 133 of the receiving portion 137.

[0060] The protruding pad 138 may protrude forward from the front surface layer 132 of the third outer profile portion 135c. The thickness T3 of the protruding pad 138 may be greater than the thickness T4 of the third outer profile portion 135c, the thickness T3 of the protruding pad 138 may be greater than the thickness T2 of the receiving portion 137, and the thickness T3 of the protruding pad 138 may be less than the thickness T1 of the flat plate portion 130P. The step D4 between the front surface layer 132 of the protruding pad 138 and the front surface layer 132 of the third outer profile portion 135c may be smaller than the steps D1, D2, and D3. The step D3 descending from the front surface layer 132 of the protruding pad 138 to the front surface layer 132 of the receiving portion 137 may be smaller than the step D1, and may be larger than the step D2.

[0061] Reference Figure 8 The side frame 140 may extend along the periphery of the composite material panel 130. The side frame 140 may be bonded to the outer contour portion 135 of the composite material panel 130 (see FIG. 1 ) by a hot melt adhesive 130H. Figure 6 ) of the front surface layer 132. For example, the side frame 140 may include a metal material such as aluminum (Al). The side frame 140 may be referred to as a guide panel 140 or a middle box 140.

[0062] Reference Fig. 9 and Fig.10 The side frame 140 may include a vertical portion 140V and a horizontal portion 140H. The vertical portion 140V may extend in the front-rear direction, and the vertical portion 140V may cover the side of the composite material panel 130. The horizontal portion 140H may extend from the vertical portion 140V in a direction crossing the vertical portion 140V, and the horizontal portion 140H may be located in front of the outer profile portion 135.

[0063] Reference Fig. 9, the outer profile 135 may be stamped from the front surface 132 of the flat plate 130P to the rear. For example, the outer profile 135 may be flattened by returning to the forging die for re-striking after being forged. For example, the thickness T1 of the flat plate 130P may be 4.0 mm, and the thickness T4 of the outer profile 135 may be 3.0 mm. The hot melt adhesive 130H may be applied on the outer profile 135, and the hot melt adhesive 130H may be located between the outer profile 135 and the horizontal portion 140H.

[0064] Reference Fig.10 , the horn UW of the ultrasonic welding machine can be located on the front side of the horizontal portion 140H, and ultrasonic vibrations are applied to the horizontal portion 140H and the hot melt adhesive 130H. Thus, the horizontal portion 140H can be ultrasonically welded to the outer profile 135 by the hot melt adhesive 130H. At this time, the front surface layer 132 of the outer profile 135 can be pressed toward the rear surface layer 133 by the horn UW, and the thickness T5 of the outer profile 135 may become smaller. For example, the thickness T5 of the outer profile 135 can be 2.4 mm to 2.5 mm. The pressing amount D6-D5 of the outer profile 135 using the horn UW can be 0.5 mm to 0.6 mm. Since such stamping of the outer profile 135 is performed during the above-mentioned ultrasonic welding, i.e., at a high temperature, it can be maintained without springing back.

[0065] Reference Fig.10 and Fig.11 , the sum T10a of the thickness T5 of the outer profile 135, the thickness of the hot melt adhesive 130H, and the thickness T10 of the horizontal portion 140H may be less than the thickness T1 of the flat portion 130P. For example, the thickness T1 of the flat portion 130P may be 4.0 mm. For example, the thickness T5 of the outer profile 135 may be 2.4 to 2.5 mm, the thickness of the hot melt adhesive 130H may be 0.1 mm, the thickness T10 of the horizontal portion 140H may be 1.1 mm, and the sum T10a of these may be 3.6 to 3.7 mm.

[0066] The display panel 110 may be located in front of the horizontal portion 140H. The first adhesive member AD1 may be located between the front surface layer 132 of the flat portion 130P and the back surface of the display panel 110, and may be combined with the flat portion 130P and the display panel 110. For example, the thickness T11 of the first adhesive member AD1 may be 0.5 mm. The second adhesive member AD2 may be located between the front surface of the horizontal portion 140H and the back surface of the display panel 110, and may be combined with the horizontal portion 140H and the display panel 110. For example, the thickness T12 of the second adhesive member AD2 may be 0.8 mm to 0.9 mm. For example, the adhesive members AD1 and AD2 may be double-sided tapes.

[0067] Thus, the display panel 110 may be combined with the composite material panel 130 and the side frame 140, and the display panel 110 may be positioned flat with respect to the composite material panel 130. In addition, the vertical portion 140V may cover the side of the display panel 110.

An electromagnetic field may be formed around the line filter LF. The rear panel 150 may vibrate under the action of the electromagnetic field generated when the line filter LF is driven. The vibration of the rear panel 150 may be transmitted to the composite panel 130 and generate vibration and / or noise. For example, as the display panel 110 becomes larger, the current value of the line filter LF increases, and the intensity of the electromagnetic field generated in the line filter LF may increase. At this time, if the distance from the line filter LF to the rear panel 150 becomes shorter, the vibration of the rear panel 150 may be increased, and if the distance from the line filter LF to the rear panel 150 becomes longer, the vibration of the rear panel 150 may be reduced. The opening 155 of the rear panel 150 corresponding to the line filter LF can prevent the rear panel 150 from vibrating due to the line filter LF. If the size of the opening 155 of the rear plate 150 formed to ensure the distance between the line filter LF and the rear plate 150 becomes larger, the rigidity of the rear plate 150 may be reduced. Therefore, the distance between the line filter LF and the rear plate 150 formed with the opening 155 can not only affect the rigidity of the rear plate 150, but also affect the noise and / or vibration generated in the rear plate 150.

[0107] The power supply unit PSU may be separated from the composite panel 130 and the rear panel 150, and the power supply unit PSU may be installed or fixed on the back of the rear panel 150. The power supply unit PSU may include a line filter LF. For example, the line filter LF may include a coil that can remove the noise of the power supply. An electromagnetic field may be formed around the line filter LF. The rear panel 150 may vibrate under the action of the electromagnetic field generated when the line filter LF is driven. The vibration of the rear panel 150 may be transmitted to the composite panel 130 and generate vibration and / or noise. For example, as the display panel 110 becomes larger, the current value of the line filter LF increases, and the intensity of the electromagnetic field generated in the line filter LF may increase. At this time, if the distance from the line filter LF to the rear panel 150 becomes closer, the vibration of the rear panel 150 can be increased, and if the distance from the line filter LF to the rear panel 150 becomes farther. Then the vibration of the rear panel 150 can be reduced.

[0108] The openings 155 and 157 of the rear plate 150 corresponding to the line filter LF can prevent the rear plate 150 from vibrating due to the line filter LF. If the size of the opening 155 of the rear plate 150 formed to ensure the distance between the line filter LF and the rear plate 150 becomes larger, the rigidity of the rear plate 150 may be reduced. Therefore, the distance between the line filter LF and the rear plate 150 formed with the opening 155 can not only affect the rigidity of the rear plate 150, but also affect the noise and / or vibration generated in the rear plate 150. For example, the current flowing in the line filter LF can be 2.8A to 3.2A, the second distance B from the line filter LF to the rear plate 150 can be 7 to 8 mm, and the first distance A from the line filter LF to the edge of the first opening 155 and / or the second opening 157 of the rear plate 150 can be more than 10 mm.
