A direction perpendicular to the long sides LS1 and LS2 and the short sides SS1 and SS2 of the display device <NUM> may be referred to as a third direction DR3 or a front-rear direction FR. Here, a side on which the display device <NUM> displays an image may be referred to as a front side, and a side opposite thereto may be referred to as a rear side.

In the following description of the display panel <NUM>, a display panel using an Organic Light Emitting Diode (OLED) will be described as an example, but the display panel <NUM> which may be applied to the present disclosure is not limited thereto.

Referring to <FIG>, the display device <NUM> includes the display panel <NUM>, a frame <NUM>, a corrugated panel <NUM>, and a mount <NUM>.

The display panel <NUM> may form a front surface of the display device <NUM> and may display an image on the front side. The display panel <NUM> may divide the image into a plurality of pixels and may output the image while controlling color, brightness, and chroma of the respective pixels. The display panel <NUM> may be divided into an active area, in which the image is displayed, and a de-active area in which the image is not displayed. The display panel <NUM> may generate light corresponding to red, green, or blue color in response to a control signal.

The frame <NUM> may form side surfaces of the display device <NUM>. The frame <NUM> is disposed at the rear of the display panel <NUM> and is coupled to the display panel <NUM>. The frame <NUM> may have an overall square ring shape. For example, the frame <NUM> may be formed of a metal material. For example, the frame <NUM> may be formed of an aluminum (Al) material.

The corrugated panel <NUM> may form a rear surface of the display device <NUM>. The corrugated panel <NUM> is disposed at the rear of the display panel <NUM> and is coupled to the frame <NUM>.

The mount <NUM> is coupled to a rear surface of the corrugated panel <NUM>. A PCB P electrically connected to the display panel <NUM> via a cable C is installed in the mount <NUM>. The PCB P may control image display of the display panel <NUM>. The PCB P may be referred to as a source PCB.

Referring to <FIG>, the corrugated panel <NUM> includes a core <NUM>, a front skin <NUM>, and a rear skin <NUM>. The core <NUM>, the front skin <NUM>, and the rear skin <NUM> may be coupled to each other.

The front skin <NUM> forms a front surface of the corrugated panel <NUM>. The rear skin <NUM> forms a rear surface of the corrugated panel <NUM>. The front skin <NUM> and the rear skin <NUM> may be formed of a metal material. For example, the front skin <NUM> and the rear skin <NUM> may be formed of an aluminum (Al) material. For example, the front skin <NUM> and the rear skin <NUM> may have a thickness of about <NUM>. The front skin <NUM> and the rear skin <NUM> may be disposed opposite to each other with respect to the core <NUM> which will be described below.

The core <NUM> is disposed between the front skin <NUM> and the rear skin <NUM>. The core <NUM> may have a corrugated shape with alternating ridges 131a and grooves 131b which are elongated. For example, the core <NUM> may have a wavy, corrugated shape. For example, the core <NUM> may have a thickness of about <NUM>.

For example, the ridges 131a and the grooves 131b may be elongated in the left-right direction LR which is an elongated direction of the display panel <NUM>. Here, the direction in which the ridges 131a and the grooves 131b are elongated may be defined as a longitudinal direction of the core <NUM>. In this case, a plurality of ridges 131a may be spaced apart from each other in the up-down direction UD. In addition, a plurality of grooves 131b may be spaced apparat from the ridges 131a in the up-down direction UD. For example, a length between the plurality of ridges 131a or a pitch which is a length between the plurality of grooves 131b may be about <NUM>. In addition, the ridges 131a or the grooves 131b may have a height of about <NUM>.

For example, the ridges 131a may come into contact with an inner surface of the front skin <NUM>, and the grooves 131b may come into contact with an inner surface of the rear skin <NUM>. By contrast, it is also possible that the ridges 131a come into contact with the inner surface of the rear skin <NUM>, and the grooves 131b come into contact with the inner surface of the front skin <NUM>, but a description thereof will be omitted for convenience of explanation.

A first hole H1 may be formed between the core <NUM> and the front skin <NUM>. The first hole H1 may include a plurality of first holes H1 which are spaced apart from each other with the respective ridges 131a being disposed therebetween. A second hole H2 may be formed between the core <NUM> and the rear skin <NUM>. The second hole H2 may include a plurality of holes H2 which are spaced apart from each other with the respective ridges 131a being disposed therebetween. The respective first and second holes H1 and H2 may be elongated in the left-right direction LR. The first and second holes H1 and H2 may pass through the left and right sides of the corrugated panel <NUM>.

Accordingly, the corrugated panel <NUM> having the core <NUM> and the display panel <NUM> coupled thereto may have improved rigidity.

Referring to <FIG> and <FIG>, the corrugated panel <NUM> may be manufacture in a process of pressing the front skin <NUM> and the rear skin <NUM> onto the core <NUM> using a plurality of rollers, and the process may be referred to as Roll-to-Roll (R2R) processing.

Referring to <FIG>, by the rotation of a pinch roller Ra serving as a driving motor, the front skin <NUM> is unwound from a front drum Da, the rear skin <NUM> is unwound from a rear drum Db, and the core <NUM> may be moved by passing through a feeding roller Rd. Further, a first adhesive 134a for coupling the front skin <NUM> to the core <NUM> may be unwound from a first drum Dc. In addition, a second adhesive 134b for coupling the rear skin <NUM> to the core <NUM> may be unwound from a second drum Db. In this case, the front skin <NUM>, the first adhesive 134a, the core <NUM>, the second adhesive 134b, and the rear skin <NUM> are stacked in this order, and may be guided by a guide roller Rc toward an oven Ov.

As the first and second adhesives 134a and 134b are melted in the oven Ov, each of the front skin <NUM> and the rear skin <NUM> may be coupled to the core <NUM>. That is, the first and second adhesives 134a and 134b may be hot-melt adhesives. For example, the first and second adhesives 134a and 134b may have a melting point of about <NUM>, and the ambient temperature of the oven Ov may be about <NUM>. For example, the peel-off force of the first and second adhesives 134a and 134b may be about <NUM> kgf or more.

Having passed through the oven Ov, the front skin <NUM>, the core <NUM>, and the rear skin <NUM> may be guided to a press roller Rb by the rotation of the pinch roller Ra, to be pressed by the press roller Rb. Accordingly, the front skin <NUM>, the core <NUM>, and the rear skin <NUM> may be coupled to each other with an improved coupling force. After passing through the pinch roller Ra, the front skin <NUM>, the core <NUM>, and the rear skin <NUM>, which are coupled to each other, may be cut by a cutter Ct, to be manufactured as the corrugated panel <NUM> of a predetermined size.

Referring to <FIG>, the press roller Rb or the pinch roller Ra may come into contact with an outer surface of each of the front skin <NUM> and the rear skin <NUM>. The press roller Rb or the pinch roller Ra may be elongated in a direction (e.g., up-down direction UD) in which the ridges 131a and the grooves 131b of the core <NUM> are alternately formed. That is, when the press roller Rb or the pinch roller Ra is rotated, the corrugated panel <NUM> may be moved in a longitudinal direction (i.e., left-right direction LR) of the core <NUM>. In this case, the front skin <NUM> and the rear skin <NUM> may be coupled to the core <NUM> sequentially from one end to the other end in the longitudinal direction of the core <NUM>. In this case, force applied by the press roller Rb or the pinch roller Ra may be distributed evenly over the plurality of ridges 131a or the plurality of grooves 131b. Accordingly, the front skin <NUM> and the rear skin <NUM>, passing through the press roller Rb or the pinch roller Ra, may be prevented from being recessed inwardly toward the core <NUM>. In addition, the front skin <NUM> and the rear skin <NUM> of the corrugated panel <NUM> may be formed to be flat. That is, a flat rear surface of the rear skin <NUM>, which forms the rear surface of the display device <NUM>, may improve surface quality per se. Further, additional operations, such as painting the rear surface of the rear skin <NUM>, attaching a sheet thereto, or the like, may be performed easily to improve the outer appearance in the esthetic sense.

In comparison, the press roller Rb or the pinch roller Ra may be elongated in a longitudinal direction (e.g., left-right direction LR) of the ridges 131a and the grooves 131b of the core <NUM>. That is, when the press roller Rb or the pinch roller Ra are rotated, the corrugated panel <NUM> may be moved in a direction perpendicular to the longitudinal direction of the core <NUM>. In this case, the front skin <NUM> and the rear skin <NUM> may be coupled to the core <NUM> sequentially from one end to the other end in the direction perpendicular to the longitudinal direction of the core <NUM>. In this case, the force applied by the press roller Rb or the pinch roller Ra may be applied individually to the respective ridges 131a or the respective grooves 131b. Accordingly, the front skin <NUM> and the rear skin <NUM> passing through the press roller Rb or the pinch roller Ra may be recessed inwardly, particularly at portions where the first and second holes H1 and H2 are formed. In addition, the front skin <NUM> and the rear skin <NUM> of the corrugated panel <NUM> may not be flat but may be formed unevenly.

Meanwhile, in addition to the R2R processing described above with reference to <FIG> and <FIG>, in which the front skin <NUM> and the rear skin <NUM> are formed to be flat, a process of sequentially stacking the front skin <NUM>, the core <NUM>, and the rear skin <NUM> followed by coupling the same may also be performed so that the front skin <NUM> and the rear skin <NUM> may be formed to be flat.

Referring to <FIG> and <FIG>, the frame <NUM> may include a side wall <NUM> and a base <NUM> (for reference, <FIG> is a cross-sectional view taken along line A-A of <FIG>, and <FIG> is a cross-sectional view taken along line B-B of <FIG>).

The side wall <NUM> may cover a side surface of the display panel <NUM> and a side surface of the corrugated panel <NUM>. The side wall <NUM> may prevent surfaces on all sides of the display panel <NUM> and surfaces on all sides of the corrugated panel <NUM> from being exposed to the outside. Accordingly, a shape of the core <NUM> of the corrugated panel <NUM> may not be visible from the outside, thereby improving surface quality of the display panel <NUM>. That is, the first and second holes H1 and H2 formed inside the corrugated panel <NUM> may not be exposed to the outside by the side wall <NUM>. For example, the side wall <NUM> may be parallel to, or may protrude further forward than, the front surface of the display panel <NUM>. For example, the side wall <NUM> may be parallel to, or may protrude further rearward than, the rear surface of the rear skin <NUM>.

The base <NUM> may protrude from the side wall <NUM>. For example, the base <NUM> may be integrally formed with the side wall <NUM>. One side surface (i.e., rear surface) of the base <NUM> may be coupled to the front surface of the front skin <NUM>, and the other surface (e.g., front surface) thereof may be coupled to the rear surface of the display panel <NUM>. In this case, the front skin <NUM> may include a first skin 132a and a second skin 132b.

The first skin 132a may face the rear surface of the display panel <NUM>. A front surface of the first skin 132a and the rear surface of the display panel <NUM> may form a first space S1. The second skin 132b may be recessed further rearwardly than the first skin 132a. The second skin 132b may face one side surface (i.e., rear surface) of the base <NUM>. The other surface (i.e., front surface) of the base <NUM> and the rear surface of the display panel <NUM> may form a second space S2.

For example, by pressing a portion of the front skin <NUM>, which is formed to be flat, with a pressing device, the second skin 132b distinguishable from the first skin 132a may be formed. In this case, a length L2 between the ridges and grooves of the core <NUM>, disposed between the second skin 132b and the rear skin <NUM>, may be smaller than a length L1 of the ridges and grooves of the core <NUM> disposed between the first skin 312a and the rear skin <NUM>.

A first adhesive member AM1 may couple the base <NUM> to the second skin 132b. The first adhesive member AM1 may be disposed between one side surface (i.e., rear surface) of the base <NUM> and a front surface of the second skin 132b. For example, the first adhesive member AM1 may be an adhesive such as a double-sided tape. In this case, the front surface of the first skin 132a may be disposed parallel to the front surface of the base <NUM>. To this end, a sum of the length L1 and a thickness T1 of the first skin 132a may be equal to a value obtained by adding a thickness T2 of the second skin 132b, a thickness T11 of the first adhesive member AM1, and a thickness T10 of the base <NUM> to the length L2. Here, the thickness T1 of the first skin 132a and the thickness T2 of the second skin 132b may be equal to each other.

The second adhesive member AM2 may couple the base <NUM> to the display panel <NUM>. The second adhesive member AM2 may be disposed between the other side surface (i.e., front surface) of the base <NUM> and the rear surface of the display panel <NUM>. For example, the second adhesive member AM2 may be an adhesive such as a double-sided tape. For example, a thickness T12 of the second adhesive member AM2 may be equal to or greater than the thickness T11 of the first adhesive member AM1.

Each of the first display panel <NUM> and the corrugated panel <NUM> may be firmly coupled to the base <NUM> by the first and second adhesive members AM1 and AM2, respectively. Accordingly, the display panel <NUM> may have sufficient rigidity by the corrugated panel <NUM>.

Referring to <FIG>, the mount <NUM> is coupled to the rear surface of the rear skin <NUM> (for reference, <FIG> is a cross-sectional view taken along line C-C of <FIG>). A third adhesive member AM3 couples the rear skin <NUM> to the mount <NUM>. The third adhesive member AM3 is disposed between the rear surface of the rear skin <NUM> and the front surface of the mount <NUM>. For example, the third adhesive member AM3 may be an adhesive such as a double-sided tape.

The front skin <NUM> includes a third skin 132c which is recessed further rearwardly than the first skin 132a, and has one side coupled to the other side of a front fastening member Ff coupled to the mount <NUM>. For example, the front fastening member Ff may be a nut, and a bolt may be fastened to the nut, thereby increasing a coupling force between the mount <NUM> and the corrugated panel <NUM>.

The rear skin <NUM> may include a fourth skin 133a and includes a fifth skin 133b. The fifth skin 133b protrudes of further forward than the fourth skin 133a, and has one side coupled to the other side of a rear fastening member Fr coupled to the mount <NUM>. For example, the rear fastening member Fr may be a nut, and a bolt may be fastened to the nut, thereby increasing a coupling force between the mount <NUM> and the corrugated panel <NUM>.

For example, a portion of the corrugated panel <NUM> may protrude rearward to form a foaming portion 130a. In this case, among internal components of the mount <NUM>, any one component <NUM> may be coupled to the foaming portion 130a.

Referring to <FIG>, the corrugated panel <NUM> may have at least one cable hole CH which is formed by passing through the front skin <NUM> and the rear skin <NUM>. For example, the cable hole CH may be adjacent to a lower end of the corrugated panel <NUM>.

The cable C for electrically connecting the display panel <NUM> and the PCB P may pass through the cable hole CH.

Referring to <FIG>, the display panel <NUM>, and the corrugated panel <NUM> coupled to the frame <NUM>, may be moved close to each other in the front-rear direction FR, to be assembled as the display device <NUM>.

Specifically, the cable C, having one end electrically connected to the display panel <NUM>, may pass through the cable hole CH to be guided rearwardly. In this case, the cable C may be inserted into the mount <NUM>, coupled to the rear surface of the rear skin <NUM>, to be electrically connected to the PCB P.

Accordingly, the PCB P may control image display of the display panel <NUM> through the cable C. Further, a path is formed in which the cable C passing through the corrugated panel <NUM> is disposed, thereby facilitating assembly of the display device <NUM> and optimizing the internal space, when compared with a case where the cable C is disposed at a position spaced apart from a region where in the corrugated panel <NUM> is disposed. In addition, the cable hole CH and the cable C passing therethrough may be covered by the mount <NUM>, and thus may not be visible from the outside, such that surface quality may be improved.

Referring to <FIG>, the cable hole CH may be formed by at least one of the front skin <NUM> and the rear skin <NUM> which is depressed inwardly toward the core <NUM> and then is punched.

Specifically, the corrugated panel <NUM> may be mounted on a die <NUM>, so that an outer surface of the rear skin <NUM> may come into contact with an upper surface of the die <NUM>, and a pressing device <NUM> may be positioned at a portion of the front skin <NUM> at which the cable hole CH is to be formed. Then, the front skin <NUM> is locally plastically deformed by a depressing operation of the pressing device <NUM>, to be maintained in an inwardly recessed state compared to other portions. Subsequently, a punching device <NUM> may be positioned at a portion of the front skin <NUM>, at which the cable hole CH is to be formed. Next, the cable hole Ch may be formed by a punching operation of the punching device <NUM>. Meanwhile, the cable hole CH may also be formed in such a manner that the corrugated panel <NUM> is mounted on the die <NUM> so that the outer surface of the front skin <NUM> may come into contact with the upper surface of the die <NUM>, and the rear skin <NUM> is depressed inwardly by the pressing device <NUM>, and then is punched by the punching device <NUM>.

Accordingly, deformation of the core <NUM> adjacent to the cable hole CH may be minimized, compared to the case where the cable hole CH is formed by only punching without depressing the front skin <NUM> or the rear skin <NUM>. That is, in the case where the cable hole CH is formed by only punching due to the first and second holes H1 and H2 positioned at portions where the cable hole CH is to be formed, the core adjacent to the cable hole CH may be deformed relatively greatly. By contrast, by compressing the size of the first and second holes H1 and H2, disposed at positions where the cable hole CH is to be formed, by the depressing operation, followed by punching, the influence of the first and second holes H1 and H2 may be reduced, thereby minimizing the deformation of the core <NUM> adjacent to the cable hole CH.

Referring to <FIG>, each frame <NUM> includes the side wall <NUM> and the base <NUM> and may include a plurality of edges with corners Co formed therebetween. For example, the plurality of edges may include first to fourth edges 120a, 120b, 120c, and 120d. The first edge 120a may correspond to the first short side SS1, the second edge 120b may correspond to the first long side LS1, the third edge 120c may correspond to the second short side SS2, and the fourth edge 120d may correspond to the second long side LS2 (see <FIG>). In this case, a first corner Co1 may be formed between the first and second edges 120a and 120b, and a second corner Co2 may be formed between the second and third edges 120b and 120c. In addition, a third corner Co3 may be formed between the third and fourth edges 120c and 120d, and a fourth corner Co4 may be formed between the fourth and first edges 120d and 120a.

For example, as the base <NUM> of each of the plurality of edges protrudes from the side wall <NUM>, a length in a longitudinal direction thereof may decrease. Here, the longitudinal direction of each of the plurality of edges may refer to a direction toward the adjacent corner Co. In this case, in the front-rear direction FR, the base <NUM> of each of the plurality of edges may have a trapezoidal shape, with a portion coupled to the side wall <NUM> having a relatively greater length.

In addition, the base <NUM> of any one of the plurality of edges at the corner Co may be spaced apart from the base <NUM> of another one by a predetermined distance. For example, a first gap g1 may be formed between the bases of the respective first and second edges 120a and 120b at the first corner Co1, and a second gap g2 may be formed between the bases of the respective second and third edges 120b and 120c at the second corner Co2. Further, a third gap g3 may be formed between the bases of the respective third and fourth edges 120c and 120d at the third corner Co3, and a fourth gap g4 may be formed between the bases of the respective fourth and first edges 120d and 120a at the fourth corner Co4.

As described above, the first to fourth gaps g1, g2, g3, and g4 are formed such that the frame <NUM> may be manufactured by a bending process, which will be described below in further detail.

Referring to <FIG>, the plurality of edges may be formed by bending the frame <NUM> a number of times corresponding to the number of corners Co. For example, the frame <NUM> may be formed in a straight shape by an extrusion process of aluminum (Al), then may be formed in an overall square ring shape by the bending process which will be described below. That is, the frame <NUM> having the straight shape may be bent four times by a bending device (not shown), thereby sequentially forming the third corner Co3, the second corner Co2, the first corner Co1, and the fourth corner Co4. As a result, the frame <NUM> may have the first to fourth edges 120a, 120b, 120c, and 120d. Further, it should be understood that in order to prevent the bases of the respective edges from interfering with each other during the bending process, the above first to fourth gaps g1, g2, g3, and g4 are formed.

In this case, one end <NUM> and the other end <NUM> of the frame <NUM> may be coupled to each other to form a closed loop. For example, the one end <NUM> and the other end <NUM> may be coupled to each other by welding. In this case, a welded portion may be subjected to an anodizing process after finishing. Accordingly, the welded portion may be neatly finished, thereby improving surface quality. In addition, as a film is formed by the anodizing process, the frame <NUM> may have improved corrosion resistance and may be easily colored. In addition, a bracket (not shown) for covering the welded portion may be provided, such that the welded portion may not be exposed to the outside.

In addition, according to another aspect of the present disclosure, the cable hole may be formed in at least any one of the front skin and the rear skin which is depressed toward the core and then is punched.

In addition, according to another aspect of the present disclosure, there is further included an adhesive member disposed between the rear surface of the rear skin and a front surface of the mount, and coupling the rear skin and the mount, wherein: the front skin further includes a third skin recessed further rearwardly than the first skin and having one side coupled to the other side of a front fastening member coupled to the mount; and the rear skin further includes a fifth skin recessed forwardly and having one side coupled to the other side of a rear fastening member coupled to the mount.

In addition, according to another aspect of the present disclosure, the one end and the other end of the frame may be coupled to each other by welding, and may be subjected to an anodizing process after finishing.

For example, a configuration "A" described in one embodiment of the invention and the drawings and a configuration "B" described in another embodiment of the invention and the drawings may be combined with each other. Namely, although the combination between the configurations is not directly described, the combination is possible except in the case where it is described that the combination is impossible.
