[0033]

[0034] Referring to FIG. 2, a material complexed 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 material complexed panel (130) may be referred to as a fiber complexed panel (130), a fiber complexed plate (130), a composite plate (130), or a middle frame (130).

[0035] The front skin (132) may form the front of the composite material panel (130). The rear skin (133) may form the rear of the composite material panel (130). The front skin (132) and the rear skin (133) may include a metal material.

[0036] For example, the front skin (132) and the rear skin (133) may be galvanized iron. As another example, the front skin (132) and the rear skin (133) may include aluminum (Al).

[0037] For example, the thickness of the front skin (132) and the rear skin (133) may be 0.2 to 0.5 millimeters. As another example, the front skin (132) and the rear skin (133) formed of a galvanized steel plate may be 0.27 millimeters. As another example, the front skin (132) and the rear skin (133) comprising aluminum may be 0.5 millimeters.

[0038] The front skin (132) and the rear skin (133) may face each other with respect to the core (131) described below. The core (131) may be positioned between the front skin (132) and the rear skin (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] The front skin (132) and / or the rear skin (133) can be bonded to the core (131) by a hot melt method. A hot melt sheet can be positioned between the front skin (132) and the core (131), and a 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 of EVA, acrylic, polyurethane, etc. having a thickness of 50 micrometers or more. After the core (131) is positioned between the front skin (132) and the rear skin (133) by the hot melt sheet, roll lamination can be performed at 190 degrees Celsius for 1 minute or more.

[0040] Accordingly, the bending rigidity and / or torsional rigidity of the display device can be improved.

[0041]

[0042] Referring to FIGS. 3 and 4, a composite material panel (130) can be manufactured through a process of pressing a front skin (132) and a rear skin (133) onto a core (131) using a plurality of rollers, and this process can be called a roll-to-roll process.

[0043] Referring to FIG. 3, according to the rotation of the pinch roller (Ra) performing the function of the driving motor, the front skin (132) can be released from the front drum (Da), the rear skin (133) can be released from the rear drum (Db), and the core (131) can be moved via the feeding roller (Rd). In addition, the first adhesive (134a) for bonding the front skin (132) to the core (131) can be released from the first drum (Dc). In addition, the second adhesive (134b) for bonding the rear skin (133) to the core (131) can be released 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) are laminated in the above order, and can be guided in the direction toward the oven (Ov) by the guide roller (Rc). The adhesive (134a, 134b) may be a hot melt sheet (134a, 134b).

[0044] In the oven (Ov), the first and second adhesives (134a, 134b) melt, and the front skin (132) and the rear skin (133) can be bonded to the core (131), respectively. For example, the melting points of the first and second adhesives (134a, 134b) may be about 150°C, and the ambient temperature of the oven (Ov) may be about 200°C. For example, the adhesive strength (peel-off force) of the first and second adhesives (134a, 134b) may be about 10 kgf or more.

[0045] The front skin (132), core (131), and rear skin (133) that have passed through the oven (Ov) can be guided to the pressing roller (Rb) and pressed by the pressing roller (Rb) according to the rotation of the pinch roller (Ra). Accordingly, the bonding force between the front skin (132), core (131), and 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) to be manufactured into a composite material panel (130) of a certain size.

[0046] Referring to FIG. 4, the pressing roller (Rb) or the pinch roller (Ra) can contact the outer surface of each of the front skin (132) and the rear skin (133). When the pressing roller (Rb) or the pinch roller (Ra) rotates, the composite material panel (130) can move in the longitudinal direction of the core (131) (i.e., 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 in the longitudinal direction of the core (131).

[0047] In addition, the front skin (132) and rear skin (133) of the composite material panel (130) can be formed flat. That is, since the rear surface of the rear skin (133) forming the rear surface of the display device (100) is formed flat, it can be easier to perform additional work, such as painting or attaching a sheet to the rear surface of the rear skin (133) for aesthetic purposes.

[0048] Meanwhile, in addition to forming the front skin (132) and the rear skin (133) flat through the roll-to-roll process described above with reference to FIGS. 3 and 4, it is also possible to combine the core (131), the front skin (132), and the rear skin (133) through a process of sequentially stacking the front skin (132), the core (131), and the rear skin (133) and then combining them.

[0154] The rear skin (133) of the receiving portion (137) may form a step (D2) that is higher than the rear skin (133) of the third outer part (135c). For example, the height of the step (D6) that is lowered from the front skin (132) of the third outer part (135c) to the front skin (132) of the receiving portion (137) may be smaller than the height of the step (D2) that is higher from the rear skin (133) of the third outer part (135c) to the rear skin (133) of the receiving portion (137). The thickness (T1) of the flat portion (130P) may be larger than the thickness (T2) of the receiving portion (137). The thickness (T4) of the third outer part (135c) may be smaller than the thickness (T1) of the flat portion (130P). The thickness (T2) of the receiving portion (137) may be greater than the thickness (T4) of the third outer part (135c).

The magnitude of the external force applied to the front skin (132) of the flat panel (130P) may be greater than the magnitude of the external force applied to the rear skin (133) of the flat panel (130P). The core (131) of the composite panel (130) can not only secure rigidity but also absorb impact.

[0156] The fastening groove (H) may protrude from the rear skin (133) of the receiving portion (137). The fastening groove (H) may be recessed in the front skin (132) of the receiving portion (137) and protrude from the rear skin (133) of the receiving portion (137). The center of the fastening groove (H) may be perforated.

[0157] The first slit (139a1, 139b1) may be formed through the front skin (132), the core (131), and / or the rear skin (133). The second slit (139a2, 139b2) may be formed through the front skin (132), the core (131), and / or the rear skin (133).

[0158]

[0159] Referring to FIGS. 29 and 30, the outer part (135) may be formed around the flat portion (130P). The outer part (135) may form a step that is lowered from the flat portion (130P). The outer part (135) may be formed by the front skin (132) being depressed while the core (131, see FIG. 2) is compressed. The outer part (135) may also be formed by the front skin (132) being depressed while the rear skin (133) is protruded while the core (131) is compressed.

[0160] The third outer part (135c) may be formed adjacent to the lower side of the flat plate portion (130P). The third outer part (135c) may form a step lowered from the flat plate portion (130P) and may be formed at the lower end of the flat plate portion (130P).

[0161] The receiving portions (137, 137a, 137b) may be formed on the third outer part (135c). The receiving portions (137, 137a, 137b) may be formed when the flat part (130P) is pressed.

For example, the receiving portions (137, 137a, 137b) may form the same plane as the third outer part (135c). For another example, the receiving portions (137, 137a, 137b) may be formed when the third outer part (135c) is pressed.

[0162] The barrier slits (SL1, SL2) may be located at the boundary between the flat portion (130P) and the receiving portion (137a, 137b). The barrier slits (SL1, SL2) may be referred to as barriers (SL1, SL2). The barrier slits (SL1, SL2) may be referred to as cutouts (SL1, SL2). The barrier slits (SL1, SL2) may be referred to as barrier cut-outs (SL1, SL2).

[0163] The barrier slits (SL1, SL2) may be formed on an inclined surface of a step lowering from the flat portion (130P) to the receiving portions (137a, 137b). The barrier slits (SL1, SL2) may be formed by cutting out a portion of the flat portion (130P) and a portion of the receiving portions (137a, 137b). The barrier slits (SL1, SL2) may be plural.

[0165] The first part (P1) can be parallel to the third part (P3). The third part (P3) can be spaced apart from the first part (P1). The second part (P2) can connect the first part (P1) and the third part (P3). The fourth part (P4) can be parallel to the sixth part (P6). The sixth part (P6) can be spaced apart from the fourth part (P4). The fifth part (P5) can connect the fourth part (P4) and the sixth part (P6).

[0166] The fourth part (P4), the fifth part (P5), and the sixth part (P6) can form one edge of the flat portion (130P). The first part (P1), the second part (P2), and the third part (P3) can form one edge of the receiving portion (137a, 137b). The seventh part (P7) and the eighth part (P8) can form one edge of the step connecting the receiving portion (137a, 137b) and the flat portion (130P).

[0167] The second distance (D2) from the lower side of the receiving portion (137a, 137b) to the third part (P3) may be greater than the first distance (D1) from the lower side of the receiving portion (137a, 137b) to the first part (P1).

[0168] The second slit (SL2) may include a first part (E1), a second part (E2), a third part (E3), a fourth part (E4), a fifth part (E5), a sixth part (E6), a seventh part (E7), and an eighth part (E8). The first part (E1), the second part (E2), and the third part (E3) may form a lower side of the second slit (SL2). The fourth part (E4), the fifth part (E5), and the sixth part (E6) may form an upper side of the second slit (SL2). The upper side of the second slit (SL2) may be parallel to the lower side of the second slit (SL2). The seventh part (E7) can connect one end of the upper side and one end of the lower side of the second slit (SL2), and the eighth part (E8) can connect the other end of the upper side and the other end of the lower side of the second slit (SL2). The seventh part (E7) can be parallel to the eighth part (E8).

[0169] The first part (E1) can be parallel to the third part (E3). The third part (E3) can be spaced apart from the first part (E1). The second part (E2) can connect the first part (E1) and the third part (E3). The fourth part (E4) can be parallel to the sixth part (E6). The sixth part (E6) can be spaced apart from the fourth part (E4). The fifth part (E5) can connect the fourth part (E4) and the sixth part (E6).

[0170] The fourth part (E4), the fifth part (E5), and the sixth part (E6) can form one edge of the flat portion (130P). The first part (E1), the second part (E2), and the third part (E3) can form one edge of the receiving portion (137a, 137b). The seventh part (E7) and the eighth part (E8) can form one edge of the step connecting the receiving portion (137a, 137b) and the flat portion (130P).

[0171] The second distance (D2) from the lower side of the receiving portion (137a, 137b) to the third part (E3) may be greater than the first distance (D1) from the lower side of the receiving portion (137a, 137b) to the first part (E1). The first slit (SL1) may be symmetrical to the second slit (SL2).

[0172] Accordingly, it is possible to improve the poor bonding of the display panel (110) to the composite material panel (130) due to the bending that occurs in the skin (132, 133) while forming the receiving portion (137a, 137b).

[0173]

[0174] Referring to FIG. 31, the plurality of barrier slits (SL1, SL2) may include a first slit (SL1), a second slit (SL2), and a third slit (SL3). The third slit (SL3) may be elongated and spaced apart from the first slit (SL1) and the second slit (SL2). The third slit (SL3) may face the receiving portion (137a, 137b) with respect to the first slit (SL1) and the second slit (SL2).

[0175] The length (L1) of the third slit (SL3) may be smaller than the distance between the seventh part (P7) of the first slit (SL1) and the seventh part (E7) of the second slit (SL2). The width (w1) of the third slit (SL3) may be smaller than the widths (w2, w3) of the first slit (SL1) and / or the second slit (SL2).

[0176] The third distance (D3) from the sixth part (P6) of the first slit (SL1) to the third slit (SL3) may be smaller than the second distance (D2) from the lower side of the receiving portion (137a, 137b) to the third part (P3) of the first slit (SL1).

[0177] Accordingly, it is possible to further improve the poor bonding of the display panel (110) to the composite material panel (130) due to the bending of the composite material panel (130).

[0178]

[0179] Referring to FIG. 32, a patterned opening (PO) may be formed on the front skin (132) or the rear skin (133). The opening pattern (PO) may also be formed on the front skin (132) and the rear skin (133). When the opening pattern (PO) is formed on both the front skin (132) and the rear skin (133), the opening pattern (PO) formed on the front skin (132) may be asymmetrical with respect to the core (131) with respect to the opening pattern (PO) formed on the rear skin (133).

[0180] The aperture pattern (PO) may be formed through the front skin (132) or the rear skin (133). The core (131) may isolate the front skin (132) and the rear skin (133). For example, the aperture pattern (PO) may not be formed in the core (131). The core (131) may cover the aperture pattern (PO). The core (131) may prevent heat from being transmitted through the composite panel (130) through the aperture pattern (PO).

[0181] The area or location where the aperture pattern (PO) is formed on the skin (132, 133) may correspond to a heat source. The aperture pattern (PO) may be distributed in a limited area. The area where the aperture pattern (PO) is distributed may be referred to as a heat control area (PO).

[0182]

[0183] Referring to FIG. 33, the thermal control area (PO) may correspond to a heat source (HA) or the area of ​​the heat source (HA). For example, the heat source (HA) may be a main board, a power supply unit, and / or a T-CON board. As another example, the heat source (HA) may be a display panel (110).

[0184] The area of ​​the heat control area (PO) may be larger than the area of ​​the heat source (HA). The area of ​​the heat source (HA) may be set to a square, and the length of one side of the heat source (HA) may be set to a first distance (Wh). In addition, the heat control area (PO) may be set to a square identical to the heat source (HA), and the length of one side of the heat control area (PO) may be set to a second distance (Wp). For example, the second distance (Wp) may be 1.2 to 1.3 times the first distance (Wh). In another example, the second distance (Wp) may be 1.25 times the first distance (Wh).

[0185] In Fig. 33, the temperature of the skin (132, 133) including the heat control area (PO) may be represented by a solid line distribution, and the temperature of the skin (132, 133) not including the heat control area (PO) may be represented by a dotted line distribution. It can be seen that the temperature of the skin (132, 133) including the heat control area (PO) is lower and maintained constant compared to the skin (132, 133) not including the heat control area (PO).

[0186] When heat is applied to the skin (132, 133) that does not include a heat control area (PO) by a heat source (HA), the skin (132, 133) may undergo thermal deformation. If the skin (132, 133) undergoes thermal deformation, the flatness of the composite panel (130) may deteriorate. The heat control area (PO) can effectively dissipate heat from the composite panel (130) and prevent thermal deformation of the composite panel (130).

[0187]

[0188] Referring to FIG. 34, the thermal control area (PO) may be rectangular. The thermal control area (PO) may form an angle (alpha) with respect to one side of the display panel (110). The right side of the thermal control area (PO) may form a certain angle with respect to the lower side of the display panel (110). For example, the angle (alpha) may be 90 degrees. In another example, the angle (alpha) may be 45 degrees.

[0189] When the angle (alpha) is 90 degrees or close to 90 degrees, the heat control effect can be improved compared to other angles. For example, the heat dissipation effect of the composite material panel (130) in the left configuration of FIG. 34 can be improved compared to the right configuration of FIG. 34.

[0190]

[0191] Referring to FIG. 35, a plurality of openings (H) may be formed in the front skin (132) or the rear skin (133). The openings (H) may be referred to as holes (H), through holes (H), or heat dissipation holes (H). The number of openings (H) may be plural. The plurality of openings (H) may form a pattern. The pattern of the openings (H) may form rows and columns. For example, the openings (H) may be arranged in 15 rows (R1 to R15) and 15 columns (C1 to C15). The size of the openings (H) may vary depending on the location.

[0192] In the first row (R1), the sizes of the openings (H) arranged sequentially from the fourth column (C4) to the twelfth column (C12) may be the same. In the first row (R1), the sizes of the openings (H) arranged from the first column (C1) to the third column (C3) and the openings (H) arranged from the thirteenth column (C13) to the fifteenth column (C15) may be the same, and may be smaller than the sizes of the openings (H) arranged from the fourth column (C4) to the twelfth column (C12).

In the second row (R2) and the third row (R3), the sizes of the apertures (H) arranged in the first column (C1) and the fifteenth column (C15) may be the same, and may be smaller than the sizes of the apertures (H) arranged from the second column (C2) to the fourteenth column (C14).

[0194] The sizes of the apertures (H) arranged sequentially from the 4th row (R4) to the 12th row (R12) may be the same.

[0195] In the 13th row (R13) and the 14th row (R14), the sizes of the apertures (H) arranged sequentially from the second column (C2) to the fourteenth column (C14) may be the same. In the 13th row (R13) and the 14th row (R14), the sizes of the apertures (H) arranged in the first column (C1) and the fifteenth column (C15) may be the same, and may be smaller than the sizes of the apertures (H) arranged from the second column (C2) to the fourteenth column (C14).

[0196] In the 15th row (R15), the sizes of the apertures (H) sequentially arranged from the 4th column (C4) to the 12th column (C12) may be the same. In the 1st row (R1), the sizes of the apertures (H) from the 1st column (C1) to the 3rd column (C3) and the apertures (H) sequentially arranged from the 13th column (C13) to the 15th column (C15) may be the same, and may be smaller than the sizes of the apertures (H) sequentially arranged from the 4th column (C4) to the 12th column (C12).

[0197] The sizes of the openings (H) sequentially arranged from the 4th column (C4) to the 12th column (C12) may be the same. The sizes of the openings (H) arranged in the first row (R1), the second row (R2), and the third row (R3) of the first column (C1) may be the same as the sizes of the openings (H) arranged in the second column (C2) and the third column (C3) of the first row (R1). The sizes of the openings (H) arranged in the 13th row (R13), the 14th row (R14), and the 15th row (R15) of the first column (C1) may be the same as the sizes of the openings (H) arranged in the second column (C2) and the third column (C3) of the 15th row (R15).

[0198] Accordingly, heat dissipation of the composite material panel (130) can be effectively achieved.

[0199]

[0200] Referring to FIG. 36, a plurality of openings (H) may be formed in the front skin (132) or the rear skin (133). The openings (H) may be referred to as holes (H), through holes (H), or heat dissipation holes (H). The number of openings (H) may be plural. The plurality of openings (H) may form a pattern. The pattern of the openings (H) may form rows and columns. For example, the openings (H) may be arranged in 15 rows (R1 to R15) and 15 columns (C1 to C15). The size of the openings (H) may vary depending on the location.

[0201] In the first row (R1), the sizes of the openings (H) arranged sequentially from the fourth column (C4) to the twelfth column (C12) may be the same. In the first row (R1), the sizes of the openings (H) arranged from the first column (C1) to the third column (C3) and the openings (H) arranged from the thirteenth column (C13) to the fifteenth column (C15) may be the same, and may be smaller than the sizes of the openings (H) arranged from the fourth column (C4) to the twelfth column (C12).

[0202] In the second row (R2) and the third row (R3), the sizes of the openings (H) sequentially arranged from the third column (C3) to the thirteenth column (C13) may be the same. In the second row (R2) and the third row (R3), the sizes of the openings (H) sequentially arranged in the first column (C1) and the fifteenth column (C15) may be the same, and may be smaller than the sizes of the openings (H) sequentially arranged from the third column (C3) to the thirteenth column (C13).

The size of the opening (H) arranged in the 14th column (C14) of the 2nd row (R2) may be smaller than the size of the opening (H) arranged in the 13th column (C13) of the 2nd row (R2), and may be larger than the size of the opening (H) arranged in the 2nd row (R2) and the 15th column (C15).

[0203] The sizes of the apertures (H) arranged sequentially from the 4th row (R4) to the 12th row (R12) may be the same.

[0204] In the 13th row (R13) and the 14th row (R14), the sizes of the apertures (H) arranged sequentially from the 3rd column (C3) to the 13th column (C13) may be the same.
