[0001] This specification relates to a display device, and more particularly to a display device with improved visibility.

Background Art

[0002] In recent years, as society has entered a full-fledged information age, the field of display devices (displays) that process and display large amounts of information has been rapidly developing. Display devices used in computer monitors, television receivers (TVs), mobile phones, etc. include organic light-emitting display devices (Organic Light Emitting Display: OLED) that emit light by themselves, and liquid crystal display devices (Liquid Crystal Display: LCD) that require a separate light source.

[0003] The application range of display devices is diverse, not only limited to computer monitors and TVs but also extending to personal portable devices. Research continues on display devices that have a large display area while having a small volume and weight.

[0004] In particular, recently, flexible display devices that can display images even when bent or folded like paper have attracted attention as next-generation display devices. Flexible display devices utilize a plastic thin-film transistor substrate that is not glass and can be classified into highly durable unbreakable, bendable that can be bent without the screen breaking, rollable that can be rolled up like a scroll, foldable that can be folded, etc. Such flexible display devices have advantages in terms of space utilization, interior design, and design, and can have various application fields.

[0005] On the other hand, a display device that includes a bending area must maintain a flat shape in the central part and a bent shape on the sides, including the corners. Therefore, shrinkage deformation occurring in the structure that supports the shape of the display panel in the bending area can prevent the display panel from shrinking smoothly, resulting in wrinkles and damage, which can lead to a decrease in the display quality of the display panel. [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] The problem that this specification aims to solve is to provide a display device in which abrupt changes in stiffness that occur at the boundary between a bending region and a non-bending region are reduced.

[0007] The problem that this specification aims to solve is to provide a display device that can improve the visibility of the boundary between a bending area and a non-bending area.

[0008] The problems described herein are not limited to those mentioned above, and other problems not mentioned can be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0009] A display device according to one embodiment of this specification includes a display panel including a non-bending area and a bending area, and a metal plate disposed below the display panel, wherein the bending area includes a first bending area corresponding to the side portion of the non-bending area and a second bending area corresponding to the corner portion of the non-bending area, the metal plate includes a first portion disposed in the non-bending area and a second portion disposed in the bending area, the first portion of the metal plate includes a plurality of first pattern portions and a plurality of second pattern portions spaced apart from each other, and the second portion of the metal plate includes a plurality of first openings and a plurality of second openings.

[0010] Specific details of other embodiments are included in the detailed description and drawings. [Effects of the Invention]

[0011] According to the embodiments of this specification, by arranging multiple patterned portions on the metal plate in the bending region and the non-bending region adjacent to it, it is possible to prevent abrupt changes in rigidity at the boundary between the bending region and the non-bending region, thereby preventing deformation of the metal plate.

[0012] According to the embodiments of this specification, by including a first pattern section, a second pattern section, and a third pattern section, in which the multiple pattern sections are arranged to be spaced apart from each other, it is possible to prevent the multiple pattern sections of the metal plate from being visible.

[0013] According to the embodiments of this specification, since the display device includes a metal plate with multiple patterned sections, it is possible to provide a lightweight display device because the individual components for supporting the display panel and ensuring visibility are not required.

[0014] The effects described herein are not limited to those exemplified above, and a wider variety of effects are included within this specification. [Brief explanation of the drawing]

[0023] The area and thickness of each configuration shown in the drawings are shown for the convenience of explanation, and this specification is not necessarily limited to the area and thickness of the shown configuration.

[0024] The respective features of the various embodiments of this specification can be partially or wholly combined or combined with each other, enabling various technical linkages and drives, and each embodiment may be implemented independently of each other or may be implemented together in a related relationship.

[0025] In the following, this specification will be described with reference to the drawings.

[0026] FIG. 1 is a schematic perspective view of a display device according to an embodiment of this specification. FIG. 2 is an enlarged view of the X region in FIG. 1. FIG. 3 is a schematic exploded perspective view of a display device according to an embodiment of this specification.

[0027] Referring to Figures 1 to 3, a display device 100 according to one embodiment of the present invention includes a display panel 110, a polarizing film 120, an adhesive layer 125, a cover window 130, a back plate 140, and a metal plate 150.

[0028] The display panel 110 is a panel on which images are displayed, and may include display elements for displaying images and circuitry for driving the display elements. For example, if the display device 100 is an organic light-emitting display device, the display elements may include organic light-emitting elements.

[0029] In the following, for the sake of convenience, we will assume that the display device 100 according to one embodiment of the present invention is a display device including an organic light-emitting element, but we are not limited thereto. Various other types of display devices, such as liquid crystal displays (LCDs) and inorganic light-emitting devices, can also be used as display devices of this disclosure.

[0030] The circuit section may include a variety of thin-film transistors, capacitors, wiring, and driver ICs for driving the organic light-emitting element.

[0031] For example, the circuit section may include, but is not limited to, a variety of configurations such as drive thin-film transistors, switching thin-film transistors, storage capacitors, gate wiring, data wiring, gate driver ICs, and data driver ICs.

[0032] The display panel 110 is an encapsulated flexible substrate on which a drive thin-film transistor and a light-emitting element are formed, and includes a flexible substrate with a very small thickness to realize flexibility, and a display element arranged on the flexible substrate.

[0033] The flexible substrate may be formed from a flexible insulating material, such as an insulating plastic substrate selected from polyimide, polyethersulfone, polyethylene terephthalate, and polycarbonate. Other examples of flexible substrates include, but are not limited to, any flexible plastic material such as polyethylene terephthalate (PET), polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), polymethyl methacrylate (PMMA), polyethylene naphthalate (PEN), polyethersulfone (PES), cycloolefin copolymer (COC), triacetylcellulose (TAC), polyvinyl alcohol (PVA), polyimide (PI), and polystyrene (PS).

[0034] Referring to Figures 1 to 3, the display panel 110 includes a non-bending area NBA and a bending area BA.

[0035] The non-bending area NBA is the area in which the display panel 110 is maintained in a flat state. The non-bending area NBA may consist entirely of the display area, or it may consist of the display area and a non-bending area surrounding the display area, but is not limited to these.

[0036] The bending area BA is the area where the display panel 110 is bent.

[0037] The bending region BA may be the region extending from the side and corner of the non-bending region NBA.

[0038] The bending area BA may be composed entirely or partially of a display area, or partially of a non-display area, but is not limited to this.

[0039] The bending region BA may include a first bending region BA1 and a second bending region BA2.

[0040] The first bending region BA1 may be a region extending from the side of the non-bending region NBA.

[0041] The second bending region BA2 may be a region extending from the corner of the non-bending region NBA.

[0042] Specifically, if the non-bending region NBA is rectangular in plan view, the first bending region BA1 may be a region that extends from the four sides of the non-bending region NBA and is bent with a specific radius of curvature.

[0043] Furthermore, if the non-bending region NBA is rectangular in plan view, the second bending region BA2 may be a region extending from the four corners and bending with a specific radius of curvature.

[0044] The first bending region BA1 and the second bending region BA2 may, but are not limited to, be positioned to surround the non-bending region NBA.

[0045] Furthermore, the first bending region BA1 and the second bending region BA2 may be arranged alternately. For example, one second bending region BA2 may be placed between two first bending regions BA1, and one first bending region BA1 may be placed between two second bending regions BA2.

[0046] On the other hand, the display device 100 according to one embodiment of the present invention may include a display area and a non-display area.

[0047] The display area is the area where multiple pixels are arranged to effectively display an image.

[0048] The hidden area may be positioned to surround the visible area.

[0049] The non-display area is an area where the image is not displayed, and various wiring, driver ICs, printed circuit boards, etc., for driving the pixels and driving circuits that are placed in the display area are located there. For example, various ICs such as gate driver ICs and data driver ICs, VSS wiring, etc., may be located in the non-display area.

[0050] Assuming that the video display surface of the display device 100 is facing forward, the polarizing film 120 can be placed on the display surface of the display panel 110 in the direction of the display surface of the display device 100.

[0051] The polarizing film 120 can perform the role of polarizing the light emitted from the display panel 110 at a polarization angle.

[0052] The polarizing film 120 emits light polarized at the polarization angle to the outside. The polarizing film 120 may also include a function to block the reflection of light from the outside, excluding the light polarized at the polarization angle.

[0053] On the other hand, although Figure 3 shows that the display device 100 includes a polarizing film 120, the polarizing film 120 may be omitted depending on the design. An adhesive layer 125 may be placed on the polarizing film 120. The adhesive layer 125 may contain a transparent adhesive material with high light transmittance.

[0054] A cover window 130 can be placed on the adhesive layer 125.

[0055] The cover window 130 can protect the display panel 110 from external impacts and prevent damage such as scratches.

[0056] The cover window 130 can be embodied in a cover made of a series of ductile plastics that are bendable, in order to provide a thin and flexible display device 100.

[0057] On the other hand, although not shown in Figure 2, a touch panel that optionally serves as a touch sensor may be placed between the display panel 110 and the cover window 130. Furthermore, the touch panel may be integrated into the display panel 110 as one or more components of the display panel 110.

[0058] The back of the display panel 110 may include a backplate 140 for supporting the display panel 110. The backplate 140 is positioned on top of two plates positioned on the back of the display panel 110 and may therefore be referred to as the top plate. The backplate 140 may be made of a polyethylene terephthalate (PET) series material. However, the disclosure is not limited thereto, and the backplate 140 may be omitted if necessary.

[0059] The backplate 140 maintains a constant curvature of the display panel 110 when the display device 100 is bent, thereby suppressing wrinkles that occur on the upper surface of the display panel 110.

[0060] Furthermore, the backplate 140 is positioned between the display panel 110 and the metal plate 150, which can suppress the phenomenon of the multiple openings in the metal plate 150 being transferred to the display screen or the display screen being distorted by the multiple openings.

[0061] A metal plate 150 for supporting the display panel 110 may be placed on the back of the backplate 140.

[0062] The metal plate 150 supports the flexible substrate that makes up the display panel 110 so that it does not sag, and can also protect the components placed on the flexible substrate from external moisture, heat, shock, etc.

[0063] The metal plate 150 is positioned as the lower of the two plates arranged on the back of the display panel 110, and therefore can be referred to as the bottom plate.

[0064] The metal plate 150 may be made of a material such as stainless steel (SUS) or amorphous metal that is rigid enough to maintain the shape of the display panel 110. However, the display device 100 described herein is not limited thereto. For example, the metal plate 150 may include a plastic material that is rigid enough to support the display panel 110, and may therefore also be called a support plate or plastic plate.

[0065] The metal plate 150 may include a first part 151 and a second part 152.

[0066] The first portion 151 of the metal plate 150 may be the portion corresponding to the non-bending area NBA of the display device 100.

[0067] The second portion 152 of the metal plate 150 may correspond to the bending region BA of the display device 100. Specifically, the second portion 152 of the metal plate 150 may correspond to the first bending region BA1 and the second bending region BA2 of the display device 100, respectively.

[0068] The structure of the metal plate 150 of the display device 100 according to one embodiment of this specification will be described below with reference to Figure 4.

[0069] Figure 4 is an enlarged view of a portion of a metal plate included in a display device according to one embodiment of this specification.

[0070] Referring to Figure 4, the metal plate 150 of the display device 100 may include a first part 151 and a second part 152.

[0071] The first portion 151 of the metal plate 150 may be the portion corresponding to the non-bending area NBA of the display device 100.

[0072] Therefore, the first portion 151 of the metal plate 150 may include a region that remains planar. That is, the first portion 151 of the metal plate 150 may include a region that is not bent at a specific radius of curvature.

[0073] The first portion 151 of the metal plate 150 may include a patterned area PA and a non-patterned area NPA.

[0074] The patterned area PA of the first portion 151 of the metal plate 150 may be positioned between the second portion 152 of the metal plate 150 and the non-patterned area NPA of the first portion 151 of the metal plate 150.

[0075] Multiple patterned sections 156, 157, and 158 may be arranged in the patterned area PA of the first portion 151 of the metal plate 150.

[0076] Specifically, in the pattern region PA of the first portion 151 of the metal plate 150, a plurality of first pattern portions 156 and a plurality of second pattern portions 157 may be arranged in the region adjacent to the first bending region BA1.

[0077] Each of the multiple first pattern sections 156 and the multiple second pattern sections 157 may contain multiple patterns.

[0078] At least one of the multiple patterns included in the multiple first pattern sections 156 and the multiple patterns included in the multiple second pattern sections 157 may have different shapes in plan view.

[0079] Each of the multiple patterns contained in the multiple first pattern sections 156 and each of the multiple patterns contained in the multiple second pattern sections 157 may be arranged spaced apart from one another in one direction (e.g., from the first bending region BA1 to the non-bending region NBA).

[0080] For example, each of the multiple patterns contained in the multiple first pattern sections 156 and the multiple patterns contained in the multiple second pattern sections 157 may be arranged in the first direction DR1, or arranged to be spaced apart from each other in the second direction DR2, which is a direction intersecting the first direction DR1.

[0081] Such multiple first pattern sections 156 and multiple second pattern sections 157 can be arranged alternately. For example, the multiple first pattern sections 156 and multiple second pattern sections 157 can be arranged alternately in the first direction DR1 or the second direction DR2.

[0082] The multiple patterns included in the multiple first pattern sections 156 and the multiple patterns included in the multiple second pattern sections 157 may be hole patterns or opening patterns, but are not limited to these.

[0083] Furthermore, multiple third pattern sections 158 may be arranged in the area of ​​the first portion 151 of the metal plate 150 that is adjacent to the second bending area BA2.

[0084] Multiple third pattern sections 158 may be arranged at the corners of the first section 151.

[0085] Multiple third pattern sections 158 can include multiple patterns.

[0086] At least one of the multiple patterns included in the multiple third pattern sections 158 may have a different shape in plan view from at least one of the multiple patterns included in each of the multiple first pattern sections 156 and the multiple second pattern sections 157.

[0087] Multiple patterns contained in multiple third pattern sections 158 can be arranged to be spaced apart from each other in the direction between the first direction DR1 and the second direction DR2.

[0088] Each of the multiple first pattern portions 156, multiple second pattern portions 157, and multiple third pattern portions 158 arranged in the pattern region PA of the first portion 151 of the metal plate 150 is positioned adjacent to the bending region BA, thereby preventing the formation of wrinkles in the metal plate 150 due to the compressive stress applied by the bending region BA.

[0089] Specifically, each of the multiple first pattern portions 156, multiple second pattern portions 157, and multiple third pattern portions 158 arranged in the pattern region PA of the first portion 151 of the metal plate 150 can play a role in mitigating the abrupt change in the rigidity of the metal plate 150 that occurs at the boundary between the first portion 151 and the second portion 152.

[0090] In other words, the compressive stress acting between the first portion 151, which is a flat section of the metal plate 150, and the second portion 152, which is a bending section, can prevent defects from occurring in the metal plate 150.

[0091] The second portion 152 of the metal plate 150 may be the portion corresponding to the bending area BA of the display device 100.

[0092] Therefore, the second portion 152 of the metal plate 150 can include a region that is bent with a specific radius of curvature.

[0093] For example, the upper surface of the metal plate 150 relative to the second portion 152 may include a bending section that is bent with a specific radius of curvature.

[0094] The second portion 152 of the metal plate 150 may include a first sub-region 152a and a second sub-region 152b.

[0095] The first sub-region 152a of the second part 152 may be positioned to correspond to the first bending region BA1 of the bending region BA.

[0096] Furthermore, the second sub-region 152b of the second part 152 may be positioned to correspond to the second bending region BA2 of the bending region BA.

[0097] Therefore, the first sub-region 152a and the second sub-region 152b can be arranged alternately. For example, one second sub-region 152b can be placed between two first sub-regions 152a, and one first sub-region 152a can be placed between two second sub-regions 152b.

[0098] The second portion 152 of the metal plate 150 may extend from the first portion 151 and be formed integrally with the first portion 151.

[0099] Specifically, if the first portion 151 of the metal plate 150 is rectangular in plan view, the first sub-region 152a of the second portion 152 of the metal plate 150 may extend from the four sides of the first portion 151 of the metal plate 150.

[0100] Furthermore, if the first portion 151 of the metal plate 150 is rectangular in plan view, the second sub-region 152b of the second portion 152 of the metal plate 150 may extend from the corner of the first portion 151 of the metal plate 150.

[0101] The first sub-region 152a of the second portion 152 of the metal plate 150 can be connected to the first portion 151 of the metal plate 150. Specifically, the first sub-region 152a of the second portion 152 of the metal plate 150 can be positioned adjacent to the pattern region PA of the metal plate 150, which has a plurality of first pattern portions 156 and a plurality of second pattern portions 157 arranged therein.

[0102] The second sub-region 152b of the second portion 152 of the metal plate 150 may be positioned adjacent to the pattern region PA of the metal plate 150, where a plurality of third pattern portions 158 are arranged.

[0103] On the other hand, the metal plate 150 may be subjected to stress at the boundary between the first portion 151 and the second portion 152 by bending the second portion 152 with a specific radius of curvature.

[0104] Specifically, when a flat metal plate is bent to have a curved shape, shrinkage deformation may occur depending on the bending direction.

[0105] In particular, the amount of shrinkage deformation may be large at the boundary between the bending region BA and the non-bending region NBA, and therefore compressive stress may be generated in various directions at the boundary between the first part 151 and the second part 152 of the metal plate 150.

[0106] Furthermore, if only the multiple first openings 153 and multiple second openings 154 are arranged in the second portion 152 of the metal plate 150, a sudden change in rigidity may occur at the boundary between the first portion 151 and the second portion 152 of the metal plate 150.

[0107] In this case, shrinkage may not proceed smoothly at the boundary between the first part 151 and the second part 152 of the metal plate 150, causing wrinkles to form, or deformation transmitted from the wrinkled boundary of the metal plate 150 may damage the display panel 110 placed on the metal plate 150 at the boundary between the bending area BA and the non-bending area NBA.

[0108] Furthermore, if wrinkles occur in the metal plate 150, these wrinkles may be visible, which can lead to a decrease in the quality of the display device 100.

[0109] If multiple openings 155 are located only in the second portion 152 of the metal plate 150, a problem may arise where a line is visible at the boundary between the bending region BA and the non-bending region NBA.

[0110] Therefore, the display device 100 according to one embodiment of this specification may include a plurality of patterned portions 156, 157, 158 and a plurality of openings 155 to prevent abrupt changes in the rigidity of the metal plate 150 at the boundary between the first portion 151 and the second portion 152 of the metal plate 150. The openings 155 may also be referred to as patterned portions or holes, similar to the plurality of patterned portions 156, 157, 158.

[0111] Specifically, each of the first sub-region 152a and the second sub-region 152b of the second portion 152 of the metal plate 150 can include a plurality of openings 155.

[0112] The multiple openings 155 may include a plurality of first openings 153 and a plurality of second openings 154.

[0113] Multiple first openings 153 and multiple second openings 154 can be arranged alternately in the first direction DR1 and the second direction DR2. Also, as shown in Figure 4, multiple first openings 153 and multiple second openings 154 are basically aligned with each other in the first direction DR1 and the second direction DR2.

[0114] The structure of the display device 100 according to one embodiment of this specification, which includes multiple pattern sections 156, 157, 158 and multiple openings 155, will be specifically described as follows.

[0115] Figure 5 is a cross-sectional view along points A and B in Figure 3. Figure 6 is a cross-sectional view along points C and D in Figure 3.

[0116] Referring to Figures 5 and 6, the display device 100 may include a back plate 140 placed on a metal plate 150, a display panel 110 placed on the back plate 140, a polarizing film 120 placed on the display panel 110, an adhesive layer 125 placed on the polarizing film 120, and a cover window 130 placed on the adhesive layer 125.

[0117] The metal plate 150 may include a plurality of patterned sections 156, 158 located in the non-bending region NBA.

[0118] Specifically, the first portion 151 of the metal plate 150 may include a plurality of first pattern portions 156 and a plurality of third pattern portions 158.

[0119] Each of the multiple first pattern sections 156 and the multiple third pattern sections 158 provided on the first portion 151 of the metal plate 150 may be a hole pattern.

[0120] Multiple first pattern sections 156 may include multiple subpatterns arranged to be spaced apart from each other. For example, multiple first pattern sections 156 may include a first subpattern 156a, a second subpattern 156b, and a third subpattern 156c, arranged to be spaced apart from each other.

[0121] On the other hand, although not shown in the drawings, the second pattern portion 157 located in the pattern area PA of the first portion 151 of the metal plate 150 may also include a plurality of subpatterns arranged to be spaced apart from each other, similar to the first pattern portion 156.

[0122] For example, the multiple second pattern sections 157 may include a fourth subpattern, a fifth subpattern, and a sixth subpattern, which are arranged to be spaced apart from each other, similar to the first pattern section 156.

[0123] Multiple first pattern sections 156 can be superimposed on the back plate 140, display panel 110, polarizing film 120, adhesive layer 125, and cover window 130.

[0124] The multiple third pattern sections 158 may include multiple subpatterns arranged to be spaced apart from each other. For example, the multiple third pattern sections 158 may include a seventh subpattern 158a, an eighth subpattern 158b, and a ninth subpattern 158c, arranged to be spaced apart from each other. In the embodiments herein, each of the first to third pattern sections is shown to include three subpatterns, but the number and shape of the subpatterns included in each of the first to third pattern sections are not limited thereto, and various other forms can be adopted as needed.

[0125] Furthermore, the metal plate 150 may include a plurality of openings 155 located in the first bending region BA1 and the second bending region BA2.

[0126] Specifically, the second portion 152 of the metal plate 150 may include a plurality of first openings 153 and a plurality of second openings 154 located in the first bending region BA1 and the second bending region BA2, respectively.

[0127] Multiple first pattern portions 156 located on the first portion 151 of the metal plate 150 may be arranged adjacent to the first bending region BA1.

[0128] Specifically, the first sub-pattern 156a of the first pattern section 156 may be positioned closer to the first bending region BA1 than the second sub-pattern 156b and the third sub-pattern 156c of the first pattern section 156.

[0129] The second sub-pattern 156b of the first pattern section 156 may be positioned closer to the first bending region BA1 than the third sub-pattern 156c of the first pattern section 156.

[0130] Multiple third pattern portions 158 located on the first portion 151 of the metal plate 150 may be arranged adjacent to the second bending region BA2.

[0131] Specifically, the seventh sub-pattern 158a of the third pattern section 158 may be positioned closer to the second bending region BA2 than the eighth sub-pattern 158b and the ninth sub-pattern 158c of the third pattern section 158.

[0132] Furthermore, the eighth sub-pattern 158b of the third pattern section 158 may be positioned closer to the second bending region BA2 than the ninth sub-pattern 158c of the third pattern section 158.

[0133] In this way, by arranging multiple first pattern portions 156 and multiple third pattern portions 158 on the first portion 151 of the metal plate 150, the compressive stress received at the boundary between the first portion 151 and the second portion 152 of the metal plate 150 can be reduced, and abrupt changes in the rigidity of the metal plate 150 can be prevented.

[0134] In particular, the multiple patterns included in the first pattern section 156 and the third pattern section 158 can distribute and reduce the compressive stress applied to the first portion 151 of the metal plate 150.

[0135] Therefore, in order to reduce the compressive stress applied to the first portion 151 of the metal plate 150, it is not necessary to enlarge the multiple patterns included in the first pattern portion 156 and the third pattern portion 158, respectively.

[0136] If the multiple patterns contained in the first pattern section 156 and the third pattern section 158 are large, the viewer may perceive multiple patterns, which can lead to a problem where the display quality of the display device 100 deteriorates.

[0137] In one embodiment of this specification, the display device 100 includes multiple patterns in each of the multiple first pattern sections 156 and multiple third pattern sections 158 arranged on the first portion 151 of the metal plate 150, thereby preventing the multiple patterns from being visible to the viewer.

[0138] Furthermore, the second portion 152 of the metal plate 150 may include a connecting portion 115, a plurality of first openings 153, and a plurality of second openings 154.

[0139] Specifically, the second portion 152 of the metal plate 150 may include a connecting portion 115, a plurality of first openings 153, and a plurality of second openings 154 in each of the first bending region BA1 and the second bending region BA2.

[0140] In the second portion 152 of the metal plate 150, a plurality of first openings 153 and a plurality of second openings 154 may be arranged to be spaced apart from each other.

[0141] The second portion 152 of the metal plate 150 may have a shape in which a connecting portion 115 is positioned between a plurality of first openings 153 and a plurality of second openings 154. The connecting portion 115 of such a second portion 152 of the metal plate 150 may be formed integrally or connected.

[0142] One end of the connecting portion 115 can be connected to the first portion 151 of the metal plate 150. Thus, the first portion 151 and the second portion 152 of the metal plate 150 can be formed integrally with each other.

[0143] In the second portion 152 of the metal plate 150, the area occupied by the plurality of first openings 153 and the plurality of second openings 154 may be configured to be larger than the area occupied by the connecting portion 115.

[0144] In this way, by arranging a plurality of first openings 153 and a plurality of second openings 154 in the second portion 152 of the metal plate 150, the metal plate 150 can be easily bent in the bending region BA.

[0145] Furthermore, by arranging a plurality of first openings 153 and a plurality of second openings 154 in the second portion 152 of the metal plate 150, the stress received at the boundary between the first portion 151 and the second portion 152 of the metal plate 150 can be reduced, thereby preventing abrupt changes in the rigidity of the metal plate 150.

[0146] The metal plate 150 of the display device 100 according to one embodiment of this specification includes a plurality of first pattern portions 156 and a plurality of third pattern portions 158 in a first portion 151 located in the non-bending region NBA, and a plurality of first openings 153 and a plurality of second openings 154 in a second portion 152 located in the bending region BA, thereby having the effect of reducing the stress generated at the boundary between the first portion 151 and the second portion 152 in each of the first portion 151 and the second portion 152.

[0147] The structure of the metal plate 150 of the display device 100 according to one embodiment of this specification will be described in detail as follows.

[0148] Figure 7 is an enlarged view of the Y region in Figure 4. Figure 8 is an enlarged view of the Z region in Figure 4.

[0149] Referring to Figures 7 and 8, the first portion 151 of the metal plate 150 may have a plurality of first pattern portions 156, a plurality of second pattern portions 157, and a plurality of third pattern portions 158.

[0150] The first subpatterns 156a of a plurality of first pattern sections 156 may be positioned between a second subpattern 156b and a first opening 153 located in the second section 152 of the metal plate 150.

[0151] The fourth subpatterns 157a of the multiple second pattern sections 157 may be positioned between the fifth subpattern 157b and the second opening 154 located in the second portion 152 of the metal plate 150.

[0152] At least two of the planar shapes of the first subpatterns 156a, 2nd subpatterns 156b, and 3rd subpatterns 156c of the multiple first pattern sections 156, and the fourth subpatterns 157a, 5th subpatterns 157b, and 6th subpatterns 157c of the multiple second pattern sections 157, may be different.

[0153] Specifically, the planar shape of the first subpattern 156a, which is positioned between the second subpattern 156b and the first opening 153, can be modified by the planar shape of the first opening 153.

[0154] Furthermore, the planar shape of the fourth subpattern 157a, which is positioned between the fifth subpattern 157b and the second opening 154, may be modified by the planar shape of the second opening 154.

[0155] The planar shape of the first opening 153 may have an outer shape that is convex on both sides in one direction and an outer shape that is concave on both sides in a direction intersecting with that direction.

[0156] For example, as shown in Figure 7, with respect to a plurality of first pattern portions 156, the planar shape of the first opening 153 located on one side of the first pattern portion 156 may have an outer shape that is convex in the second direction DR2 and concave in the first direction DR1.

[0157] Furthermore, the planar shape of the first subpattern 156a, which is positioned on one side of the first opening 153, may be a concave outer shape on the side facing the first opening 153. The remaining area of ​​the first subpattern 156a may be a convex outer shape in plan view.

[0158] In other words, the first opening 153 has a convex shape on the side facing the first subpattern 156a in a plan view. The first subpattern 156a has a concave shape on the side facing the first opening 153 in a plan view. For example, the side of the first opening 153 facing the first subpattern 156a and the side of the first subpattern 156a facing the first opening 153 may correspond to or complement each other.

[0159] Thus, because the first opening 153 and the first sub-pattern 156a each have related shapes in plan view, the degree to which compressive stress applied to the boundary between the first portion 151 and the second portion 152 is absorbed can be increased. In particular, by reducing the compressive stress acting between the first opening 153 and the first sub-pattern 156a, the change in stiffness in the region between the first opening 153 and the first sub-pattern 156a can be reduced.

[0160] Furthermore, the planar shape of the second opening 154 may be the shape obtained by rotating the first opening 153 by 90°.

[0161] Specifically, the planar shape of the second opening 154 may have a concave shape in one direction and a convex shape in a direction intersecting that direction.

[0162] For example, as shown in Figure 7, with respect to a plurality of second pattern portions 157, the planar shape of the second opening 154 located on one side of the second pattern portion 157 may have a concave shape in the second direction DR2 and a convex shape in the first direction DR1.

[0163] On other sides, two connecting portions 115 extending in one direction (e.g., a first direction DR1 or a second direction DR2) and two connecting portions 115 extending in another direction intersecting that direction (a second direction DR2 or a first direction DR1) may intersect to form a first opening 153 or a second opening 154.

[0164] Specifically, some of the multiple connecting parts 115 may extend in the first direction DR1, and other parts may extend in the second direction DR2.

[0165] The connecting portion 115 extending in the first direction DR1 may have a line shape in which concave and convex regions are alternately arranged with respect to a straight line extending in the first direction DR1.

[0166] The connecting portion 115 extending in the second direction DR2 may have a line shape in which concave and convex regions are alternately arranged with respect to a straight line extending in the second direction DR2. In other words, the connecting portion 115 extending in the first direction DR1 or the second direction DR2 may have a wave shape or a wave pattern as shown in Figure 7. For example, the first pattern portion 156 (or first sub-pattern 156a) may be arranged in correspondence with the first opening 153 and aligned with adjacent first openings 153, and the second pattern portion 157 (or fourth sub-pattern 157a) may be arranged in correspondence with the second opening 154 and aligned with adjacent second openings 154.

[0167] In a region where one first opening 153 is located, each of the two connecting portions 115 extending in the first direction DR1 may have a concave region, and each of the two connecting portions 115 extending in the second direction DR2 may have a convex region.

[0168] Furthermore, in the region where one second opening 154 is located, each of the two connecting portions 115 extending in the first direction DR1 may have a convex region, and each of the two connecting portions 115 extending in the second direction DR2 may have a concave region.

[0169] Furthermore, the fourth sub-pattern 157a, which is positioned on one side of the second opening 154, may have a convex shape on the side facing the second opening 154 in a plan view.

[0170] In other words, the second opening 154 may have a concave shape on the side facing the fourth subpattern 157a in a plan view, and the fourth subpattern 157a may have a convex shape on the side facing the second opening 154 in a plan view. For example, the side of the second opening 154 facing the fourth subpattern 157a and the side of the fourth subpattern 157a facing the second opening 154 may correspond to or complement each other.

[0171] Thus, because the second opening 154 and the fourth sub-pattern 157a each have shapes that are related to each other in a plan view, the degree to which compressive stress applied to the boundary between the first portion 151 and the second portion 152 is absorbed can be increased. In particular, by reducing the compressive stress acting between the second opening 154 and the fourth sub-pattern 157a, the change in stiffness in the region between the second opening 154 and the fourth sub-pattern 157a can be reduced.

[0172] Furthermore, the second subpattern 156b, the third subpattern 156c, the fifth subpattern 157b, and the sixth subpattern 157c may be formed to be circular in plan view.

[0173] However, the present invention is not limited thereto, and the second subpattern 156b, third subpattern 156c, fifth subpattern 157b, and sixth subpattern 157c may have a variety of shapes, such as semicircles, semiellipses, or polygons.

[0174] On the other hand, the center of the first opening 153 located in the second portion of the metal plate 150 can be separated by a first distance L1 from the center of the first subpattern 156a of the first pattern portion 156 located on one side of the first opening 153.

[0175] Here, the center of the first opening 153 may be the point where the major axis and minor axis of the first opening 153 intersect.

[0176] Furthermore, the center of the first subpattern 156a may refer to the point that becomes the center of a virtual circle when a virtual circle is drawn based on the convex outer edge of the first subpattern 156a.

[0177] Here, the first distance L1 may mean the shortest straight-line distance from the center of the first opening 153 to the first sub-pattern 156a in the direction in which the sub-patterns included in the first pattern section 156 are arranged.

[0178] Furthermore, the center of the first subpattern 156a may be separated from the center of the second subpattern 156b by a second distance L2. The center of the second subpattern 156b may be separated from the center of the third subpattern 156c by a third distance L3.

[0179] Here, the center of the second subpattern 156b refers to the circular center of the planar shape of the second subpattern 156b, and the center of each of the third subpatterns 156c may refer to the point that is the circular center of the planar shape of the third subpattern 156c.

[0180] The second distance L2 may represent the shortest straight-line distance from the center of the concave outer surface of the first subpattern 156a to the center of the second subpattern 156b in the direction in which the subpatterns included in the first pattern section 156 are arranged.

[0181] Furthermore, the first distance L1 may be longer than the second distance L2 and the third distance L3. The second distance L2 may be longer than the third distance L3.

[0182] In other words, the first distance L1, the second distance L2, and the third distance L3 can decrease progressively.

[0183] For example, the second distance L2 and the third distance L3 may decrease by 12% to 25% compared to the first distance L1.

[0184] Here, if the second distance L2 and the third distance L3 decrease by more than 25% compared to the first distance L1, the spacing between the multiple subpatterns included in the first pattern section 156 becomes narrower, which can make the process of forming the subpatterns difficult. In addition, a significant reduction in the size of some subpatterns may lead to a problem where the compressive stress applied to the boundary between the first section 151 and the second section 152 of the metal plate 150 cannot be adequately absorbed.

[0185] Furthermore, if the second distance L2 and the third distance L3 decrease to less than 12% of the first distance L1, it becomes difficult to form multiple subpatterns within the limited pattern area PA. As a result, some subpatterns may become larger without being separated during the process, and a problem may arise where parts of the subpatterns become visible.

[0186] Therefore, the first sub-pattern 156a, the second sub-pattern 156b, and the third sub-pattern 156c included in the first pattern section 156 are located at the boundary between the first section 151 and the second section 152 of the metal plate 150, but may be located in a region where a large compressive stress is applied.

[0187] In this way, by arranging the first subpattern 156a, the second subpattern 156b, and the third subpattern 156c in regions where a large compressive stress is applied, the compressive stress applied to the metal plate 150 can be effectively absorbed.

[0188] Furthermore, in a plan view, the multiple patterns included in the second pattern section 157 may have the same shape. For example, the multiple patterns in the second pattern section 157 may be circular. The diameters of the fourth sub-pattern 157a, the fifth sub-pattern 157b, and the sixth sub-pattern 157c included in the second pattern section 157 may be different.

[0189] For example, the diameter of the fourth subpattern 157a may be larger than the diameters of the fifth subpattern 157b and the sixth subpattern 157c, respectively. The diameter of the fifth subpattern 157b may be larger than the diameter of the sixth subpattern 157c.

[0190] Therefore, the distance between the center of the second opening 154 and the center of the fourth subpattern 157a, the distance between the center of the fourth subpattern 157a and the center of the fifth subpattern 157b, and the distance between the center of the fifth subpattern 157b and the center of the sixth subpattern 157c can decrease progressively.

[0191] In other words, with respect to one direction (e.g., the second direction DR2), the diameter of the multiple patterns included in the second pattern section 157 may gradually decrease as it moves away from the second section 152 of the metal plate 150.

[0192] In this case, the diameters of the fifth subpattern 157b and the sixth subpattern 157c may be reduced to a range of 16% to 30% of the diameter of the fourth subpattern 157a, but the present invention is not limited thereto.

[0193] Here, if the diameters of the fifth subpattern 157b and the sixth subpattern 157c decrease by more than 30% compared to the diameter of the fourth subpattern 157a, a problem may arise where some of the subpatterns included in the second pattern section 157 become significantly smaller, making it impossible to adequately absorb the compressive stress applied to the boundary between the first section 151 and the second section 152 of the metal plate 150.

[0194] Furthermore, if the diameters of the fifth subpattern 157b and the sixth subpattern 157c are reduced to less than 16% of the diameter of the fourth subpattern 157a, it becomes difficult to form multiple subpatterns within the limited pattern region PA. In this case, some subpatterns may enlarge without being separated during the process, potentially leading to the problem of parts of the subpatterns being visible.

[0195] Thus, with reference to one direction (e.g., second direction DR2), the diameter of the multiple patterns included in the second pattern section 157 gradually decreases as it moves away from the second portion 152 of the metal plate 150. As a result, the fourth sub-pattern 157a, fifth sub-pattern 157b, and sixth sub-pattern 157c included in the second pattern section 157 may be located at the boundary between the first portion 151 and the second portion 152 of the metal plate 150, and in a region where a large compressive stress is applied.

[0196] Furthermore, by ensuring that the fourth subpattern 157a, the fifth subpattern 157b, and the sixth subpattern 157c are not visible, the good image quality provided by the display device 100 can also be ensured.

[0197] On the other hand, the distance between at least one of the multiple subpatterns included in the first pattern section 156 and at least one of the multiple subpatterns included in the second pattern section 157 can be arranged at equal intervals.

[0198] Specifically, the distances K1 and K2 between the third sub-pattern 156c included in the first pattern section 156 and the sixth sub-pattern 157c of the second pattern section 157, which is arranged adjacent to the third sub-pattern 156c, can be kept constant.

[0199] For example, referring to Figure 7, the distance K1 from the center of one third subpattern 156c to the center of an adjacent sixth subpattern 157c may be the same as the distance K2 from the center of the sixth subpattern 157c to the center of another adjacent third subpattern 156c.

[0200] At least some of the multiple first pattern sections 156 and at least some of the multiple second pattern sections 157 may be arranged at equal intervals.

[0201] By arranging at least a portion of the multiple first pattern portions 156 and at least a portion of the multiple second pattern portions 157 at equal intervals, the compressive stress applied to the boundary between the first portion 151 and the second portion 152 of the metal plate 150 can be uniformly absorbed.

[0202] For example, if there is a region between the first portion 151 and the second portion 152 of the metal plate 150 in which the multiple first pattern portions 156 and the multiple second pattern portions 157 are not arranged, compressive stress may concentrate in the region in which the multiple first pattern portions 156 and the multiple second pattern portions 157 are not arranged, causing wrinkles to occur in the metal plate 150.

[0203] In contrast, the metal plate 150 of the display device 100 according to one embodiment of this specification can prevent the concentration of compressive stress in a specific area by arranging at least a portion of the plurality of first pattern portions 156 and at least a portion of the plurality of second pattern portions 157 at equal intervals. Furthermore, although the plurality of first pattern portions 156 and the plurality of second pattern portions 157 are described separately, it should be noted that they may have the same configuration except for the sub-parts within the plurality of first pattern portions 156 and the plurality of second pattern portions 157 that are closest to the second portion 152 of the metal plate 150. Therefore, the plurality of first pattern portions 156 and the plurality of second pattern portions 157 may be referred to as the plurality of pattern portions below.

[0204] Referring to Figure 8, the multiple third pattern sections 158 may include a seventh subpattern 158a, an eighth subpattern 158b, and a ninth subpattern 158c. The seventh subpattern 158a, the eighth subpattern 158b, and the ninth subpattern 158c may be arranged to be spaced apart from each other in the direction between the first direction DR1 and the second direction DR2.

[0205] Some of the multiple seventh subpatterns 158a may be positioned between the first opening 153 and the eighth subpattern 158b.

[0206] Some of the other seventh subpatterns 158a may be positioned between the second opening 154 and the eighth subpattern 158b.

[0207] Some of the multiple seventh subpatterns 158a may be positioned between the connecting portion 115 and the eighth subpattern 158b.

[0208] Furthermore, the planar shape of the seventh subpattern 158a may differ from the planar shapes of the eighth subpattern 158b and the ninth subpattern 158c, respectively.

[0209] For example, the planar shape of the seventh subpattern 158a may be semicircular, and the planar shapes of the eighth subpattern 158b and the ninth subpattern 158c may each be circular.

[0210] The seventh subpattern 158a may be positioned such that its convex portion faces the eighth subpattern 158b in a plan view, but is not limited to this arrangement.

[0211] On the other hand, in one third pattern section 158 arranged on the metal plate 150, the distance M1 from the center of the seventh subpattern 158a to the center of the eighth subpattern 158b may be longer than the distance M2 from the center of the eighth subpattern 158b to the center of the ninth subpattern 158c.

[0212] For example, the distance M2 from the center of the 8th subpattern 158b to the center of the 9th subpattern 158c may be reduced by 12% to 25% compared to the distance M1 from the center of the 7th subpattern 158a to the center of the 8th subpattern 158b.

[0213] Here, the center of the seventh subpattern 158a can mean the point that is the center of a virtual circle drawn based on the convex outer edge of the seventh subpattern 158a.

[0214] Furthermore, the center of the eighth subpattern 158b may refer to the central point of the circular planar shape of the eighth subpattern 158b, and the center of the ninth subpattern 158c may refer to the central point of the circular planar shape of the ninth subpattern 158c.

[0215] Through this, the diameters of the seventh subpattern 158a, the eighth subpattern 158b, and the ninth subpattern 158c included in the third pattern portion 158 can progressively decrease as they move away from the second portion 152 of the metal plate 150, with reference to the direction between the first direction DR1 and the second direction DR2.

[0216] For example, the diameters of the eighth subpattern 158b and the ninth subpattern 158c may be reduced by 16% to 30% compared to the seventh subpattern 158a, but are not limited to this.

[0217] Thus, with reference to one direction (e.g., the direction between the first direction DR1 and the second direction DR2), the diameter of the multiple patterns included in the third pattern portion 158 gradually decreases as it moves away from the second portion 152 of the metal plate 150. As a result, the seventh sub-pattern 158a, the eighth sub-pattern 158b, and the ninth sub-pattern 158c may be located at the boundary between the first portion 151 and the second portion 152 of the metal plate 150, and in a region where a large compressive stress is applied.

[0218] Furthermore, by ensuring that the seventh subpattern 158a, the eighth subpattern 158b, and the ninth subpattern 158c are not visible, the good image quality provided by the display device 100 can also be ensured.

[0219] Furthermore, multiple ninth subpatterns 158c may be arranged at equal intervals.

[0220] Specifically, when a plurality of subpatterns contained in one third pattern section 158 (hereinafter referred to as the first group) located closest to the first bending region BA1 of the display device 100 are arranged in the first direction DR1 or the second direction DR2, a plurality of subpatterns contained in another third pattern section 158 (hereinafter referred to as the second group) located closest to the first group may be located on a virtual line separated by an angle a with respect to the first direction DR1 and the second direction DR2.

[0221] Furthermore, multiple subpatterns included in another third pattern section 158 located on one side of the second group, which is closest to the first group, may be located on a virtual line separated by an angle b with respect to a virtual line on which the multiple patterns included in the second group are arranged.

[0222] Here, angles a and b may be the same. In other words, the multiple third pattern sections 158 are arranged in an equiangular distribution between the first direction DR1 and the second direction DR2, so that two adjacent third pattern sections 158 maintain the same spacing.

[0223] For example, angles a and b can be in the range of 2° to 11.25°.

[0224] When angles a and b are less than 2°, it is difficult to form multiple subpatterns within the limited pattern area PA, and some subpatterns may become larger without being separated during the process, potentially leading to the problem of parts of the subpatterns being visible.

[0225] Furthermore, if angles a and b exceed 11.25°, the compressive stress acting at the boundary between the second bending region BA2 and the non-bending region NBA of the metal plate 150 cannot be sufficiently absorbed, which may result in defects in the metal plate 150.

[0226] In this way, by arranging at least some of the third pattern portions 158 among the multiple third pattern portions 158 at equal intervals, the compressive stress applied to the boundary between the second bending region BA2 and the non-bending region NBA of the metal plate 150 can be uniformly absorbed.

[0227] Figure 9 shows the change in stiffness applied to the boundary between the first and second parts of the metal plate of the display device according to the comparative example. Figure 10 shows the change in stiffness applied to the boundary between the first and second parts of the metal plate of the display device according to the embodiment.

[0228] The metal plate of the display device according to the comparative example has a structure in which a plurality of first pattern portions, a plurality of second pattern portions, and a plurality of third pattern portions are not arranged on the first portion of the metal plate.

[0229] The metal plate 150 of the display device 100 according to the embodiment has a structure in which a plurality of first pattern portions 156, a plurality of second pattern portions 157, and a plurality of third pattern portions 158 are arranged on a first portion 151 of the metal plate 150.

[0230] In Figures 9 and 10, the change in shading between the bending region BA and the adjacent non-bending region NBA indicates a change in stiffness.

[0231] Referring to Figure 9, it can be seen that the metal plate in the comparative example exhibits a rapid change in stiffness in the non-bending region NBA adjacent to the bending region BA.

[0232] A sudden change in the rigidity of a metal plate can cause problems such as deformation of the metal plate's shape.

[0233] In contrast, it can be seen that the metal plate 150 according to the embodiment exhibits a gradual change in stiffness in the non-bending region NBA adjacent to the bending region BA.

[0234] In this case, the deformation occurring in the metal plate 150 is significantly reduced.

[0235] In other words, by arranging a plurality of first pattern portions 156, a plurality of second pattern portions 157, and a plurality of third pattern portions 158 at the boundary between the bending region BA and the non-bending region NBA of the metal plate 150, the compressive stress applied to the boundary between the bending region BA and the non-bending region NBA is reduced, thereby preventing defects such as wrinkles in the metal plate 150.

[0236] Although embodiments of this specification have been described in more detail above with reference to the attached drawings, this specification is not necessarily limited to these embodiments and can be modified and implemented in various ways within the scope of the technical concept of this specification. Accordingly, the embodiments disclosed herein are for illustrative purposes only, not to limit the technical concept of this specification, and the scope of the technical concept of this specification is not limited by such embodiments. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive.
