[0033] Hereinafter, a display panel using an organic light-emitting diode (OLED) for the display panel 110 will be described as an example, but the display panel 110 applicable to the present disclosure should not be construed as being limited to these examples.
[0034] The display panel 110 forms the front surface of the display device 100 and can display an image forward. The display panel 110 can divide an image into a plurality of pixels and output the image by combining the color, brightness, and saturation per pixel. The display panel 110 can be divided into an active area where an image is displayed and a de-active area where an image is not displayed. The display panel 110 can generate light corresponding to the color of red, green, or blue according to a control signal.
[0035] Referring to FIG. 2, it can include a material complexed panel (130), a core (131), a front skin (132), and a rear skin (133). The core 131, the front skin 132, and the rear skin 133 can be coupled to each other. The material complexed panel 130 can be referred to as a fiber complexed panel (130), a fiber composite board, a fiber complexed plate (130), a fiber composite plate, a material complexed plate 130, or a frame 130.
[0036] The front skin 132 can form the front surface of the material complexed panel 130. The rear skin 133 can form the rear surface of the material complexed panel 130. The front skin 132 and the rear skin 133 can include an aluminum (Al) material. As another example, the front skin 132 and the rear skin 133 can be galvanized iron sheets. 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 with respect to the core 131.
[0037] The core 131 can be positioned between the front skin 132 and the rear skin 133. The core 131 can include fibers. The core 131 can be formed of a composite material. The core 131 can include main fibers and binder fibers. The binder fibers can be mixed among the main fibers.
[0038] The hot-melt sheet can be positioned between the front skin 132 and the core 131. Also, the hot-melt sheet can be positioned 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 such as EVA, acrylic, or polyurethane having a thickness of 50 micrometers or more. The core 131 and the hot-melt sheet can be aligned with the front skin 132 and the rear skin 133 at a high temperature (e.g., about 190 - 200 °C) for 1 minute or more.
[0039] Therefore, the composite material panel 130 can improve the bending stiffness and / or torsional stiffness of the display device.
[0040] Referring to FIGS. 3 and 4, the composite material panel 130 can be manufactured through a process of pressing the front skin 132 and the rear skin 133 onto the core 131 using a plurality of rollers, and such a process can be referred to as an R2R (Roll-to-Roll) process.
[0041] Referring to FIG. 3, in response to the rotation of the pinch roller Ra that performs the function of the drive motor, the front skin 132 can be loosened from the front drum Da, the rear skin 133 can be loosened from the rear drum Db, and the core 131 can be moved via the feed roller Rd. Then, the first adhesive 134a for bonding the front skin 132 to the core 131 can be loosened from the first drum Dc. Also, the second adhesive 134b for bonding the rear skin 133 to the core 131 can be removed from the second drum Db. In this case, the front skin 132, the first adhesive 134a, the core 131, the second adhesive 134b, and the rear skin 133 can be laminated in the above order and can be guided in the direction toward the oven (Ov) by the guide roller Rc. The adhesives 134a and 134b can be hot melt sheets 134a and 134b.
[0042] The first and second adhesives 134a and 134b can be melted in the oven Ov, and the front skin 132 and the rear skin 133 may be bonded to the core 131. For example, the melting points of the first and second adhesives 134a and 134b can be about 150°C, and the ambient temperature of the oven (Ov) can be about 200°C. For example, the adhesive force (Peel-off force) of the first and second adhesives 134a and 134b can be about 10 kgf or more.
[0043] The front skin 132, the core 131, and the rear skin 133 that have passed through the oven Ov can be guided to the crimping roller Rb in response to the rotation of the pinch roller Ra and can be crimped by the crimping roller Rb. Thereby, the bonding force between the front skin 132, the core 131, and the rear skin 133 can be further increased. The mutually bonded front skin 132, core 131, and rear skin 133 can be cut by the cutter Ct after passing through the pinch roller Ra and can be manufactured into a composite material panel 130 of a certain size.
[0044] Referring to FIG. 4, the crimping roller Rb or the pinch roller Ra can contact the outer surfaces of the front skin 132 and the rear skin 133, respectively. When the crimping roller Rb or the pinch roller Ra rotates, the composite material panel 130 can be moved in the longitudinal direction of the core 131. At this time, in the longitudinal 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.
[0045] Also, the front skin 132 and the rear skin 133 of the composite material panel 130 can be formed flat. That is, by forming the back surface of the rear skin 133 that forms the back surface of the display device 100 flat, it becomes possible to easily perform additional operations such as painting the back surface of the rear skin 133 or attaching a sheet of paper for appearance finishing. Alternatively, the flat rear skin 133 can itself form the back surface of the display device 100.
[0046] On the other hand, in addition to the R2R process described above with reference to FIGS. 3 and 4, the composite material panel 130 can be manufactured through steps such as sequentially laminating the front skin 132, the core 131, and the rear skin 133 and then joining them to each other.
[0047] Referring to FIG. 5, the core 131 can include a main core 131a and a binder core 131b. The main core 131a can include a first fiber made of PET (polyethylene terephthalate) material and a second fiber made of LM (long material) material. For example, the respective ratios of the first fiber and the second fiber in the main core 131a can be 50%. The binder core 131b can include fibers made of an acrylic material.
[0048] The front skin 132 can include aluminum (Al) material or galvanized iron, and can be joined to the binder core 131b via a first hot melt adhesive 134a.
[0049] The rear skin 133 can include an aluminum (Al) material or galvanized iron, and can be coupled to the main core 131a via the second hot melt adhesive 134b.
[0050] The front skin 132 can be positioned closer to the display panel 110, see FIG. 16, than the rear skin 133, and can be exposed to a relatively higher temperature environment than the rear skin 133. That is, a temperature difference may occur between the front skin 132 and the rear skin 133. For example, the temperature difference between the front skin 132 and the rear skin 133 can be about 4°C.
[0051] At this time, the hot melt adhesives 134a and 134b can be formed of a multi-layer structure of a fiber material. The hot melt adhesives 134a and 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 a synthetic fiber material. For example, the first layer 1341 can include a nylon material and can be positioned between the second layer 1342 and the third layer 1343. For example, the second layer 1342 and the third layer 1343 can include a PU (polyurethane) material.
[0052] Thereby, due to the stretching characteristics of each layer of the composite material panel 130, the warping phenomenon due to the thermal deformation of the composite material panel 130 caused by the temperature difference between the front skin 132 and the rear skin 133 can be minimized.
[0053] Referring to FIG. 6, the composite material panel 130 can include a flat plate portion 130P, an outer peripheral portion 135, and a housing portion 137. The front skin 132 of the composite material panel 130 can define the front surfaces of the flat plate portion 130P, the outer peripheral portion 135, and the housing portion 137, respectively.
[0054] The outer peripheral portion 135 can be formed around the flat plate portion 130P. The outer peripheral portion 135 can be formed while being pressed rearward from the flat plate portion 130P. The first outer peripheral portion 135a can be formed along the upper side of the flat plate portion 130P. The second outer peripheral portion 135b can be formed along the right side of the flat plate portion 130P. The third outer peripheral portion 135c can be formed along the lower side of the flat plate portion 130P. The fourth outer peripheral portion 135d can be formed along the left side of the flat plate portion 130P.
[0055] The accommodating portion can be formed between the flat plate portion 130P and the third outer peripheral portion 135c. The accommodating portion 137 can be formed while being pressed rearward from the flat plate portion 130P and / or the third outer peripheral portion 135c.
[0056] The cable hole 136 can be formed to penetrate the accommodating portion 137 in the front-rear direction. For example, a plurality of cable holes 136a, 136b can be adjacent to each other.
[0057] Referring to FIG. 7, the thickness T1 of the flat plate portion 130P can be greater than the thickness T2 of the accommodating portion 137. The step D1 between the front skin 132 of the flat plate portion 130P and the front skin 132 of the accommodating portion 137 can be greater than the step D2 between the rear skin 133 of the flat plate portion 130P and the rear skin 133 of the accommodating portion 137.
[0058] The thickness T4 of the third outer peripheral portion 135c can be greater than the thickness T2 of the accommodating portion 137. The step D2 between the rear skin 133 of the third outer peripheral portion 135c and the rear skin 133 of the accommodating portion 137 can be the same as the step D2 between the rear skin 133 of the flat plate portion 130P and the rear skin 133 of the accommodating portion 137.
[0059] The protruding pad 138 can protrude forward from the front skin 132 of the third outer peripheral portion 135c. The thickness T3 of the protruding pad 138 can be greater than the thickness T4 of the third outer peripheral portion 135c, can be greater than the thickness T2 of the accommodating portion 137, and can be smaller than the thickness T1 of the flat plate portion 130P. The step D4 between the front skin 132 of the protruding pad 138 and the front skin 132 of the third outer peripheral portion 135c can be smaller than the steps D1, D2, and D3. The step D3 that descends from the front skin 132 of the protruding pad 138 to the front skin 132 of the accommodating portion 137 can be smaller than the step D1 and can be greater than the step D2.
[0060] Referring to FIG. 8, the side frame 140 can extend along the periphery of the composite material panel 130. The side frame 140 can be coupled to the front skin 132 of the outer portion (135, see FIG. 6) of the composite material panel 130 via the hot melt adhesive 130H. For example, the side frame 140 can include a metal material such as aluminum (Al). The side frame 140 can be referred to as a guide panel 140 or a middle cabinet 140.
[0061] Referring to FIGS. 9 and 10, the side frame 140 can include a vertical portion 140V and a horizontal portion 140H. The vertical portion 140V can extend in the front-rear direction and can cover the side surface of the composite material panel 130. The horizontal portion 140H can extend from the vertical portion 140V in a direction intersecting the vertical portion 140V and can be located in front of the outer peripheral portion 135.
[0062] Referring to FIG. 9, the outer peripheral portion 135 can be formed while being pressed rearward by the front skin 132 of the flat plate portion 130P. For example, the outer peripheral portion 135 can be re-struck and flattened after forging. For example, the thickness T1 of the flat plate portion 130P can be 4.0 mm, and the thickness T4 of the outer peripheral portion 135 can be 3.0 mm. The hot melt adhesive 130H can be applied on the outer peripheral portion 135 and can be located between the outer peripheral portion 135 and the horizontal portion 140H.
[0063] Referring to FIG. 10, the horn (UW) of the ultrasonic welder can be positioned on the front surface of the horizontal portion 140H, and ultrasonic vibration can be applied to the horizontal portion 140H and the hot melt adhesive 130H. Thereby, the horizontal portion 140H can be ultrasonically welded to the outer portion 135 via the hot melt adhesive 130H. At this time, the front skin 132 of the outer portion 135 can be pressed in the direction of the rear skin 133 by the horn UW, and the thickness T5 of the outer portion 135 can be reduced. For example, the thickness T5 of the outer portion 135 can be 2.4 to 2.5 mm. The pressing amount D6 - D5 of the outer portion 135 by the horn UW can be 0.5 to 0.6 mm. Since such pressing of the outer portion 135 is performed during the aforementioned ultrasonic welding, that is, at a high temperature, it can be held without spring back.
[0064] Referring to FIGS. 10 and 11, the total T10a of the thickness T5 of the outer portion 135, the thickness of the hot melt adhesive 130H, and the thickness T10 of the horizontal portion 140H may be smaller than the thickness T1 of the flat plate portion 130P. For example, the thickness T1 of the flat plate portion 130P can be 4.0 mm. For example, the thickness T5 of the outer portion 135 can be 2.4 to 2.5 mm, the thickness of the hot melt adhesive 130H can be 0.1 mm, the thickness T10 of the horizontal portion 140H can be 1.1 mm, and the total T10a of these can be 3.6 to 3.7 mm.
[0065] The display panel 110 can be positioned in front of the horizontal portion 140H. The first adhesive member AD1 can be positioned between the front skin 132 of the flat plate portion 130P and the rear surface of the display panel 110, and can be coupled to the flat plate portion 130P and the display panel 110. For example, the thickness T11 of the first adhesive member AD1 can be 0.5 mm. The second adhesive member AD2 can be positioned between the front surface of the horizontal portion 140H and the rear surface of the display panel 110, and can be coupled to the horizontal portion 140H and the display panel 110. For example, the thickness T12 of the second adhesive member AD2 can be 0.8 to 0.9 mm. For example, the adhesive members AD1 and AD2 can be double-sided tapes.
[0066] As a result, the display panel 110 can be coupled to the composite material panel 130 and the side frame 140, and can be positioned flat with respect to the composite material panel 130. Also, the vertical portion 140V can cover the side surface of the display panel 110.
[0067] Referring to FIG. 12 together with FIG. 8, the side frame 140 can include a first part 141, a second part 142, a third part 143, a fourth part 144, and a fifth part 145.
[0068] The first part 141 can extend along the first outer contour portion 135a (see FIG. 6) and can include a first horizontal portion 141H (see FIG. 9) and a first vertical portion 141V.

[0098] The power supply unit PSU can be separated from the composite material panel 130 and the rear plate 150, and can be placed on or fixed to the back surface of the rear plate 150. The power supply unit PSU can include a line filter LF. For example, the line filter LF includes a coil and can remove power noise. An electromagnetic field can be formed around the line filter LF. The rear plate 150 may vibrate due to the electromagnetic field generated while the line filter LF is driven. The vibration of the rear plate 150 can generate vibration and / or noise while being transmitted to the composite material panel 130. For example, as the display panel 110 becomes larger, the current value of the line filter LF may increase and the strength of the electromagnetic field generated by the line filter LF may increase. At this time, when the distance from the line filter LF to the rear plate 150 decreases, the vibration of the rear plate 150 may increase, and when the distance from the line filter LF to the rear plate 150 increases, the vibration of the rear plate 150 may decrease.

When 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 increases, the rigidity of the rear plate 150 may decrease. Therefore, the distance between the line filter LF and the opening 155 formed on the rear plate 150 not only affects the rigidity of the rear plate 150, but may also affect the noise and / or vibration generated by the rear plate 150. For example, the current flowing through the line filter LF can be 3.5A to 4.3A, the second distance B from the line filter LF to the rear plate 150 can be 7 to 8 millimeters, and the first distance A from the line filter LF to the edge of the opening 155 of the rear plate 150 can be 15 mm or more.

[0102] The first line 155a can form a long side. The third line 155c faces the first line 155a and may be shorter than the first line 155a. The fifth line 155e faces the first line 155a and may be shorter than the first line 155a and / or the third line 155c. The fifth line 155e can be parallel to the third line 155c. The distance between the third line 155c and the first line 155a may be shorter than the distance between the fifth line 155e and the first line 155a. The second line 155b forms a short side and can connect the first line 155a and the third line 155c.

[0105] For example, the first line filter LF1 can be separated from the first line 155a, the second line 155b, and / or the third line 155c by a distance A or more. As another example, the second line filter LF2 can be separated from the fourth line 155d, the fifth line 155e, and / or the sixth line 155f by a distance A or more. As another example, the third line filter LF3 can be separated from the edge of the second opening 157 by a distance A or more.
[0106] The power supply unit PSU can be separated from the composite material panel 130 and the rear plate 150, and can be mounted or fixed on the back surface of the rear plate 150. The power supply unit PSU can include a line filter LF. For example, the line filter LF can include a coil and can remove power noise. An electromagnetic field can be formed around the line filter LF. The rear plate 150 can vibrate due to the electromagnetic field generated while the line filter LF is driven. The vibration of the rear plate 150 can generate vibration and / or noise while being transmitted to the composite material panel 130. For example, as the display panel 110 becomes larger, the current value of the line filter LF can increase and the strength of the electromagnetic field generated by the line filter LF can increase. At this time, when the distance from the line filter LF to the rear plate 150 approaches, the vibration of the rear plate 150 may increase, and when the distance from the line filter LF to the rear plate 150 increases, the vibration of the rear plate 150 may decrease.
[0107] The opening 155 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. When 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 increases, the rigidity of the rear plate 150 may decrease. Therefore, the distance between the line filter LF and the rear plate 150 formed by the opening 155 not only affects the rigidity of the rear plate 150, but also can affect the noise and / or vibration generated in the rear plate 150. For example, the current flowing through the line filter LF can be 2.8 A to 3.2 A, the second distance B from the line filter LF to the rear plate 150 can be 7 to 8 millimeters, and the first distance A from the line filter LF to the edge of the opening 155 of the rear plate 150 can be 20 millimeters or more. Thereby, not only can the rigidity of the rear plate 150 be ensured, but also the vibration and / or noise of the rear plate 150 that may occur due to the drive of the line filter LF can be prevented.
[0108] Referring to FIGS. 22 and 23 together with FIG. 19, the opening 155 can include a first line 155a, a second line 155b, a third line 155c, a fourth line 155d, a fifth line 155e and / or a sixth line 155f.

The fifth line 155e can be formed by protruding from a part of the fourth line 155d. The distance from the second line 155b to the fifth line 155e may be smaller than the distance from the second line 155b to the fourth line 155d.
[0111] The length of the fifth line 155e may be greater than the length of the sixth line 155f. The sixth line 155f can face the second line 155b. The sixth line 155f can connect the first line 155a and the fourth line 155d.
[0112] The first line filter LF1 is formed by the first line 155a and the second line 155b. It can be located adjacent to the corner. The second line filter LF2 can be located adjacent to the corner formed by the first line and the sixth line, and can be located between the first line filter LF1 and the fourth line 155d.

The fifth line filter LF5 can be located adjacent to the corner formed by the third line 155c and the fourth line 155d between the second line 155b and the fourth line 155d.
[0113] The line filters LF1, LF2, LF3, LF4, LF5, LF can be separated from the lines 155a, 155b, 155c, 155d, 155e, 155f of the opening 155 by a distance of at least a certain amount. The line filter LF and the lines 155a, 155b, 155c, 155d, 155e, 155f of the opening 155 can be separated by a distance of at least the first distance A.
[0114] For example, the first line filter LF1 can be separated from the first line 155a and / or the second line 155b by a first distance A or more. As another example, the second line filter LF2 can be separated from the fourth line 155d and / or the sixth line 155f by a first distance A or more. As another example, the third line filter LF3 can be separated from the fourth line 155d and / or the fifth line 155e by a first distance A or more.

As another example, the fifth line filter LF5 can be separated from the fourth line 155d and / or the third line 155c by a first distance A or more.
[0115] The power supply unit PSU is separated from the composite material panel 130 and the rear plate 150, and can be mounted or fixed on the back surface of the rear plate 150. The power supply unit PSU can include a line filter LF. For example, the line filter LF includes a coil and can remove power noise. An electromagnetic field can be formed around the line filter LF. The rear plate 150 can vibrate due to the electromagnetic field generated while the line filter LF is driven. The vibration of the rear plate 150 can generate vibration and / or noise while being transmitted to the composite material panel 130. For example, as the display panel 110 becomes larger, the current value of the line filter LF increases, and the strength of the electromagnetic field generated by the line filter LF increases. At this time, when the distance from the line filter LF to the rear plate 150 approaches, the vibration of the rear plate 150 increases, and when the distance from the line filter LF to the rear plate 150 increases, the vibration of the rear plate 150 may decrease. The opening 155 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. When 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 increases, the rigidity of the rear plate 150 may decrease. Therefore, the distance between the line filter LF and the opening 155 formed on the rear plate 150 not only affects the rigidity of the rear plate 150, but also may affect the noise and / or vibration generated by the rear plate 150. For example, the current flowing through the line filter LF can be 5A to 5.4A, and the second distance B from the line filter LF to the rear plate 150 can be 7 to 8 millimeters. The first distance A from the line filter LF to the edge of the opening 155 of the rear plate 150 can be 20 millimeters or more. Thereby, not only can the rigidity of the rear plate 150 be ensured, but also the vibration and / or noise of the rear plate 150 that may be generated by the driving of the line filter LF can be prevented.
