[0004] Recently, curved display devices that display images not only on the front but also on the side (or curved surface) are widely used. The curved display device may include a curved window and a curved display panel attached to the curved window. The curved window and the curved display panel may have shapes corresponding to the shape of the curved display device.

[0005] An external device such as a driver chip and / or a printed circuit film may be mounted on one side of the side portion of the curved display panel. The length of the side portion may be longer than the other side portions of the curved display panel. In addition, with the application of the new generation of mobile communication technology (5G), more channels are required, so the length of the printed circuit film tends to be longer.

[0064] References and Attachments Figure 1 The advantages and features of the present invention and the methods for achieving these can be clearly seen from the embodiments described in detail below. However, the present invention can be presented in a variety of different forms and is not limited to the embodiments disclosed below. These embodiments are only provided to make the disclosure of the present invention complete and to fully inform the scope of the invention to those with ordinary knowledge in the technical field to which the present invention belongs. The present invention is defined only by the scope of the claims.

[0065] When an element or layer is mentioned as being "on" another element or layer, it includes a case where the element is immediately above the other element or where the other layer or element is interposed therebetween. Throughout the specification, the same reference numerals refer to the same constituent elements.

[0066] Although the terms first, second, etc. are used to describe various components, these components are obviously not limited to these terms. These terms are only used to distinguish one component from another component. Therefore, the first component mentioned below can obviously also be the second component within the technical concept of the present invention.

[0067] Hereinafter, specific embodiments will be described with reference to the accompanying drawings.

[0068] Figure 1 is a perspective view of a window clamp composite structure according to one embodiment.

[0069] Reference Figure 1 According to an embodiment, the window clamp composite structure 10 may include a window clamp 20 and a protection cover 30 connected to the window clamp 20. The window clamp 20 may include a main clamp portion 21 and at least one side clamp portion connected to the main clamp portion 21.

[0070] The main clamp part 21 may have a rectangular shape in a plane. For example, the main clamp part 21 may include long sides extending in the first direction DR1 and short sides extending in the second direction DR2. The main clamp part 21 may be located in a plane including the first direction DR1 and the second direction DR2.

[0071] In the following embodiments, the first direction DR1 and the second direction DR2 are different directions and intersecting each other, for example, directions intersecting vertically in a plan view. The third direction DR3 is a direction intersecting a plane where the first direction DR1 and the second direction DR2 are located, for example, a direction intersecting vertically with both the first direction DR1 and the second direction DR2. Figure 1 In the embodiment, the first direction DR1 may be the same as the extending direction of the long side of the main clamp part 21, and the second direction DR2 may be the same as the extending direction of the short side of the main clamp part 21. However, the directions mentioned in the embodiment should be understood as relatively opposite directions, and the embodiment is not limited to the mentioned directions.

[0072] There may be a plurality of side clamp parts. The plurality of side clamp parts may be bent and extended from each side of the main clamp part 21 in the thickness direction (e.g., the third direction DR3). For example, the plurality of side clamp parts may include a first long side clamp part 22, a second long side clamp part 23, a first short side clamp part 24, and a second short side clamp part 25.

[0073] The first long side clamp portion 22 can be bent (or bent) along the thickness direction and extended from the other long side of the second direction DR2 of the main clamp portion 21, the second long side clamp portion 23 can be bent (or bent) along the thickness direction and extended from one long side of the second direction DR2 of the main clamp portion 21, the first short side clamp portion 24 can be bent (or bent) along the thickness direction and extended from one short side of the first direction DR1 of the main clamp portion 21, and the second short side clamp portion 25 can be bent (or bent) along the thickness direction and extended from the other short side of the main clamp portion 21 along the first direction DR1.

[0074] The window fixture 20 can play a role in fixing the curved window described later. The curved window can include a main window portion corresponding to the main fixture portion 21 of the window fixture 20 and a side window portion corresponding to each fixture portion 22 to 25. The side window portion can be bent and extended from each edge of the main window portion in the thickness direction. The degree (or angle) of each fixture portion 22 to 25 bent from the main fixture portion 21 can be the same as or smaller than the degree of each side window portion of the curved window bent from the main window portion.

[0075] For example, each side window portion can be bent and extended from the boundary (or side) with the main window portion in a manner having a predetermined curvature with the boundary (or side) of the main window portion, and can extend in the thickness direction at the point where the bending ends. In this case, from the perspective of conformity with the side window portion, each clamp portion 22 to 25 can be bent and extended from the boundary (side of the main clamp portion 21) with the main clamp portion 21 in a manner having a predetermined curvature with the boundary (side of the main clamp portion 21), and can extend in the thickness direction at the point where the bending ends.

[0076] In some embodiments, each side window portion may be bent from the boundary (or edge) with the main window portion in a substantially non-curvature manner (bent at approximately 90°) and extend in the thickness direction. In this case, each clamp portion 22 to 25 may be bent from the boundary (edge ​​of the main clamp portion 21) with the main clamp portion 21 in a substantially non-curvature manner (bent at approximately 90°) and extend in the thickness direction.

[0077] The lengths extending along the extending directions of the respective clip portions 22 to 25 (eg, the second direction DR2 in the case of the long-side clip portions and the first direction DR1 in the case of the short-side clip portions) may be the same as each other.

[0078] Each of the clamp parts 22 to 25 may be connected to the main clamp part 21, but may be arranged to be separated from each of the adjacent clamp parts 22 to 25. For example, the first long side clamp part 22 may be arranged to be separated from the adjacent second short side clamp part 25 and the first short side clamp part 24, and the second long side clamp part 23 may be arranged to be separated from the adjacent second short side clamp part 25 and the first short side clamp part 24. However, it is not limited thereto, and each of the clamp parts 22 to 25 may be connected to each other.

[0079] The protection cover 30 may be connected to at least one side clamp portion. For example, the protection cover 30 may be connected to the second short side clamp portion 25.

[0080] The protective cover 30 may include a conductive material. For example, the protective cover 30 may include a metal, a metal alloy, or a metal oxide. For example, the protective cover 30 may include aluminum (Al) or stainless steel (SUS), etc., but is not limited thereto.

[0081] Figure 2 is along Figure 1 Cross-sectional view of the I-I' line cutting.

[0082] Reference Figure 2 , the window fixture 20 may include an inner surface 20a, an outer surface 20b, and a lower surface 20c connecting the inner surface 20a and the outer surface 20b. As described later, the curved window may be directly located on the inner surface 20a of the window fixture 20. In this case, the curved window may be in direct contact with the inner surface 20a of the window fixture 20, and may be spaced apart from the outer surface 20b of the window fixture 20.

[0083] The curved window plays a role in protecting the display panel PN. The curved window can be made of a transparent material. For example, the curved window can be made of glass or plastic.

[0084] In the case where the curved window includes glass, the glass may be ultra-thin glass (UTG: Ultra Thin Glass) to thin film glass. In the case where the glass is composed of an ultra-thin film or a thin film, it may have flexible properties and may be able to bend, fold, and curl. For example, the thickness of the glass may be in the range of 10 μm to 300 μm, specifically, glass with a thickness of 30 μm to 80 μm or about 50 μm may be applicable. The glass of the curved window may include soda-lime glass, alkali aluminosilicate glass, borosilicate glass, or lithium aluminosilicate glass. In order to have greater strength, the glass of the curved window may include chemically strengthened glass or thermally strengthened glass. Chemical strengthening may be achieved by an ion exchange treatment process in an alkaline salt. The ion exchange treatment process may also be performed more than twice.

[0085] In the case where the curved window includes plastic, it can be more advantageous in presenting flexible characteristics such as folding. Examples of plastics that can be applied to the curved window include, but are not limited to, polyimide, polyacrylate, polymethyl methacrylate (PMMA: polymethylmethacrylate), polycarbonate (PC: polycarbonate), polyethylene naphthalate (PEN: polyethylenenaphthalate), polyvinylidene chloride (polyvinylidene chloride), polyvinylidene difluoride (PVDF: polyvinylidene difluoride), polystyrene, ethylene vinyl alcohol copolymer (ethylene vinylalcohol copolymer), polyethersulfone (PES: polyethersulphone), polyetherimide (PEI: polyetherimide), polyphenylene sulfide (PPS: polyphenylenesulfide), polyallylate, triacetyl cellulose (TAC: tri-acetyl cellulose), cellulose acetate propionate (CAP: cellulose acetate propionate), etc. The plastic curved window can be constructed to include one or more of the plastic substances listed above.

[0086] The inner surface 20a and the outer surface 20b of the window fixture 20 may be located at the main fixture portion 21, the first short side fixture portion 24, and the second short side fixture portion 25, respectively. The lower surface 20c of the window fixture 20 may be located at the short side fixture portions 24 and 25.

[0087] The window fixture 20 may further include a protrusion PT protruding from the lower surface 20c of the second short side fixture portion 25 in the thickness direction (e.g., the third direction DR3). The protrusion PT may be located at the center of the lower surface 20c of the second short side fixture portion 25, but the position of the protrusion PT on the lower surface 20c of the second short side fixture portion 25 is not limited thereto. The protrusion PT may function as a combination between the window fixture 20 and the protective cover 30.

[0088] The protective cover 30 may include a receiving groove H corresponding to the protrusion PT of the window fixture 20. The protrusion PT of the window fixture 20 may be received in the receiving groove H of the protective cover 30 so that the protective cover 30 and the window fixture 20 may be combined with each other. The shape of the protrusion PT and the shape of the receiving groove H may be designed in various ways so that the protrusion PT can be clamped in the receiving groove H.

[0089] The protective cover 30 and the window fixture 20 can be combined by various widely known combination relationships. As one example, as described above, the protective cover 30 and the window fixture 20 can be combined in a manner that the protrusion PT is clamped into the receiving groove H. As another example, the receiving groove H can be formed as a nut, and the protrusion PT can be formed as a bolt, so that the protective cover 30 and the window fixture 20 can be combined in a bolt / nut manner. In addition, the receiving groove H and the protrusion PT can also be combined by an adhesive.

[0090] The outer side of the protective cover 30 may be aligned with the outer surface 20b of the window fixture 20, and the inner side of the protective cover 30 may protrude inwardly from the inner surface 20a of the window fixture 20. The curved window described below may be located at the portion where the inner side of the protective cover 30 protrudes inwardly from the inner surface of the window fixture 20.

[0091] Figure 3 is a perspective view showing a curved window being fixed to a window fixture composite structure according to an embodiment. Figure 4 is along Figure 3 Cross-sectional view of the II-II' line cutting.

[0092] Reference Figure 3 as well as Figure 4 , the curved window W may be arranged on the inner surface 20a of the window fixture 20. The main window portion may be arranged to correspond to the main fixture portion 21, and each side window portion may be arranged to correspond to each fixture portion 22 to 25. For example, the first side window portion may correspond to the first long side fixture portion 22, the second side window portion may correspond to the second long side fixture portion 23, the third side window portion may correspond to the first short side fixture portion 24, and the fourth side window portion may correspond to the second short side fixture portion 25.

[0093] Each side window portion is not bent from the initial main window portion, but is located in the same plane as the initial main window portion. If the initial main window portion and the side window portions that are not bent from the initial main window portion are fixed to the window clamp 20 and arranged, then the side window portions that are not bent from the initial main window portion can be bent from the main window portion along the thickness direction according to the corresponding shape of the clamps 22 to 25.

[0094] The degree to which each side window portion of the curved window W is bent from the main window portion may be the same as or greater than the degree (or angle) to which each clamp portion 22 to 25 is bent from the main clamp portion 21 .

[0095] In order to connect the curved window W with the display panel PN described later (see Figure 5) between the laminated parts, the window fixture 20 can play the role of fixing the curved window W. For example, the method of fixing the curved window W as the window fixture 20 may include fixing by means of a vacuum hole. Specifically, a vacuum hole can be formed in the main fixture part 21 of the window fixture 20 where the curved window W is arranged and at least a part of each fixture part 22 to 25, and the curved window W can be fixed to the window fixture 20 through the vacuum hole. However, the method of fixing the curved window W by the window fixture 20 is not limited to this, and a variety of widely known technologies can also be applied.

[0096] The curved window W may include an inner surface, an outer surface, and a lower surface connecting the inner surface of the curved window W and the outer surface of the curved window W. If the curved window W is fixed to the window fixture 20 via the vacuum hole, the outer surface of the curved window W may directly contact the inner surface 20 a of the window fixture 20 .

[0097] The lower surface 20c of each clamp portion 21 to 25 of the window clamp 20 may be aligned with the end (or lower surface) of the side window portion corresponding to each clamp portion 21 to 25 of the curved window W. The protective cover 30 may cover the end (or lower surface) of the second side window portion of the curved window W, the lower surface 20c of the second short side clamp portion 25, and the protrusion PT in the thickness direction. The protective cover 30 may directly contact the end (or lower surface) of the second side window portion of the curved window W and the lower surface 20c of the second short side clamp portion 25.

[0098] When the curved window W and the display panel (refer to Figure 5 During the lamination process of the display panel PN), the protective cover 30 can prevent the printed circuit film FPC (refer to Figure 5 The printed circuit film FPC) is bent, the edge area of ​​the display panel PN is bent, and the printed circuit film FPC is attached.

[0099] Figure 5 is a perspective view of a display panel according to an exemplary embodiment. Figure 6 It shows that according to Figure 5 A plan view of a fourth non-display area of ​​a display panel, a driving chip and a printed circuit film.

[0100] Reference Figure 5 as well as Figure 6 Examples of the display panel PN may include an organic light emitting display panel, a micro LED display panel, a nano LED display panel, a quantum dot light emitting display panel, a liquid crystal display panel, a plasma display panel, a field emission display panel, an electrophoretic display panel, an electrowetting display panel, etc. Hereinafter, as an example of the display panel PN, a case where an organic light emitting display panel is applied is shown.

[0101] The shape of the display panel PN may be substantially the same as that of the curved window W.

[0102] The display panel PN may include a main area and an edge area located around the main area. The main area of ​​the display panel PN may be located at the center of the display panel PN, and the edge area of ​​the display panel PN may be located at the edge of the main area.

The printed circuit film FPC may further include a connector electrically connected to an external device. The printed circuit film FPC may transmit various drive signals applied through the connector to the driver chip IC and / or a plurality of pixels of each display area of ​​the display panel PN.

[0117] Figure 5 Each edge region of the exemplary display panel PN shown may be bent and extended from the main display area DA0 along the thickness direction by a line deformation process of the display panel PN described later.

[0118] Figure 5 The edge regions of the exemplary display panel PN shown in the figure, which are bent from the main display area DA0 along the thickness direction by the linear deformation process, can be respectively connected to the curved window W (refer to Figure 3 ) is attached corresponding to the side window portion.

[0119] Figure 7It is a simulation diagram showing a situation where the protective cover supports the display panel and the printed circuit film on the outside during the lamination process between the curved window and the display panel.

[0120] Reference Figure 5 , Figure 6 as well as Figure 7 The first edge area of ​​the display panel PN can be combined corresponding to the second side window portion of the curved window W, the second edge area can be combined corresponding to the first side window portion of the curved window W, the third edge area can be combined corresponding to the third side window portion of the curved window W, and the fourth edge area can be combined corresponding to the fourth side window portion of the curved window W.

[0121] In addition, since a driving chip IC and a printed circuit film FPC are also arranged in the fourth edge area of ​​the display panel PN, the fourth edge area of ​​the display panel PN can have a larger extension length than other first edge areas along the extension direction to the third edge areas (for example, the extension direction of the first edge area and the second edge area is the second direction DR2, and the extension direction of the third edge area and the fourth edge area is the first direction DR1).

[0122] Also, the printed circuit film FPC disposed in the fourth edge region may protrude further toward the outside than an end portion of the fourth edge region (the third sub non-display area NDA43 ).

[0123] As mentioned above, Figure 5 Each edge region of the exemplary display panel PN shown in the figure can be bent and extended from the main display region DA0 along the thickness direction by a linear deformation process of the display panel PN to be fixed to the window fixture 20 (refer to Figure 1 as well as Figure 2 ) of the fixture parts 22 to 25 (refer to Figure 1 as well as Figure 2 ) shape matches.

[0124] In an embodiment in which the lengths extending in the extending directions of the clamping portions 22 to 25 (for example, the second direction DR2 in the case of the long-side clamping portions and the first direction DR1 in the case of the short-side clamping portions) are the same as each other, the ends of the first edge region to the third edge region of the display panel PN may be aligned with the lower surface ( Figure 2 20c), however, the peripheral portion including the end of the fourth edge region of the display panel PN and the printed circuit film FPC may protrude further in the lower direction than the lower surface 20c of the second short side clamp portion 25. In other words, in the thickness direction, a large step difference may occur between the end of the printed circuit film FPC and the lower surface 20c of the second short side clamp portion 25 of the window clamp 20.

[0125] As described later, after the curved window W fixed to the window fixture 20 is brought into contact with the first bonding component AM1 arranged on a surface of the display panel PN, and a predetermined pressure is applied to the upper part of the window fixture 20 by a laminating device, the main window portion of the curved window W is first bonded to the main display area DA0 of the display panel PN, and the shape pad SP expands along the outer side of the first direction DR1 (hereinafter, the expansion direction) due to the predetermined pressure applied from the upper part. The shape pad SP expanded along the first direction DR1 can move the edge area of ​​the display panel PN along the expansion direction, so that each edge area of ​​the display panel PN can be bonded to the corresponding side window portion of the curved window W through the first bonding component AM1. The first bonding component AM1 can be an optically transparent bonding component. The optically transparent bonding component may include an optically transparent adhesive OCA or an optically transparent resin OCR.

[0126] However, during the process of combining the edge areas of the display panel PN with the corresponding side window portions of the curved window W through the first combining component AM1, the peripheral portion of the end portion of the fourth edge area of ​​the display panel PN, which protrudes further in the downward direction than the lower surface 20c of the second short side clamp portion 25, and the printed circuit film FPC may be bent along the expansion direction due to the fourth side window portion of the curved window W and the second short side clamp portion 25.

[0127] like Figure 5 As shown, since a plurality of first pads connected to the driver chip IC, a first signal line connected to the first pad, a plurality of second pads connected to the printed circuit film FPC, and a second signal line connected to the second pad are arranged in the fourth edge region of the display panel PN, if the peripheral portion including the end of the fourth edge region is bent, the first signal line and the second signal line may be broken. The breakage of the first signal line and the second signal line may cause poor screen driving. In addition, if the printed circuit film FPC that transmits various driving signals to the driver chip IC and / or multiple pixels in each display area of ​​the display panel PN is bent, the multiple circuit signal lines on the printed circuit film FPC may also be broken. The breakage of multiple circuit signal lines on the printed circuit film FPC may cause poor screen driving.

[0128] However, as described above, the window fixture composite structure 10 according to an embodiment may include a protective cover 30 covering the end (or lower surface) of the second side window portion of the curved window W and the lower surface 20c of the second short side fixture portion 25 in the thickness direction. The protective cover 30 may support the peripheral portion of the end of the fourth edge region of the display panel PN and the printed circuit film FPC which are more protruding than the lower surface 20c of the second short side fixture portion 25 in the lower direction on the outside (for example, along the expansion direction). More specifically, the protective cover 30 may be combined with the lower surface 20c of the second short side fixture portion 25, so as to play a role in compensating for the step difference between the peripheral portion of the end of the fourth edge region and / or the printed circuit film FPC and the second short side fixture portion 25.

[0129] Accordingly, in the process of combining each edge area of ​​the display panel PN with the corresponding side window portion of the curved window W through the first combining component AM1, the peripheral portion of the end of the display panel PN including the fourth edge area and the printed circuit film FPC which protrude further in the downward direction than the lower surface 20c of the second short side clamp portion 25 can be prevented from bending along the expansion direction by the protective cover 30.

[0130] Therefore, it is possible to prevent the first signal line and the second signal line from being disconnected due to bending of the peripheral portion including the end portion of the fourth edge area and / or the printed circuit film FPC that transmits various driving signals to the driving chip IC and / or multiple pixels in each display area of ​​the display panel PN, thereby preventing poor screen driving in advance.

In the manufacturing method of a display device including a process of bonding a display panel to a curved window described later, the guide film GF may cover and support the display panel, and the ends of the plurality of film portions GF1 to GF4 may be fixed by clamps CL1 to CL4, respectively. In the guide film GF in which the ends of the plurality of film portions GF1 to GF4 are fixed by clamps CL1 to CL4, respectively, when the clamps CL1 to CL4 are lowered, the plurality of film portions GF1 to GF4 may be bent, so that the first edge area to the fourth edge area of ​​the display panel on the plurality of film portions GF1 to GF4 may be bent at the same time.

[0161] The main film part GF0 may be located at the center of the guide film GF. The main film part GF0 may be substantially the same as the planar shape of the shape pad SP.

[0169] The second bonding member AM2 may include an adhesive or a paste, respectively. The second bonding member AM2 may include an ultraviolet curing adhesive, an ultraviolet curing paste, or an ultraviolet curing resin that is cured by reacting with ultraviolet rays.

[0170] After the second bonding member AM2 is attached to the display panel and the bonding process between the display panel and the curved window is completed, it can be removed from the display panel. In order to easily remove the second bonding member AM2 from the display panel by ultraviolet rays, as described above, the second bonding member AM2 may include an adhesive, a paste, or a resin that reacts with ultraviolet rays to harden.

[0171] The main film portion GF0 of the guide film GF may be arranged to overlap the shape pad SP in the thickness direction. The main film portion GF0 may be arranged to completely overlap the shape pad SP, so that each film portion GF1 to GF4 may be arranged not to overlap the shape pad SP in the thickness direction.

[0172] Each film portion GF1 to GF4 of the guide film GF may be fixed by clamps CL1 to CL4. Each clamp CL1 to CL4 may be arranged at ends on one surface (or upper surface) and another surface (or lower surface) of each film portion GF1 to GF4 to fix each film portion GF1 to GF4.

[0173] The first clamping member CL1 and the second clamping member CL2 may extend along the first direction DR1 , and the third clamping member CL3 and the fourth clamping member CL4 may extend along the second direction DR2 .

[0175] Guide roller portions GR1 to GR4 may be connected to each clamping member CL1 to CL4. The first guide roller portion GR1 may be connected to the first clamping member CL1 and arranged on a surface (or upper surface) of the first film portion GF1. The first guide roller portion GR1 may be arranged between the first clamping member CL1 and the main film portion GF0. The first guide roller portion GR1 may extend along the first direction DR1. The second guide roller portion GR2 may be connected to the second clamping member CL2 and arranged on a surface (or upper surface) of the second film portion GF2. The second guide roller portion GR2 may be arranged between the second clamping member CL2 and the main film portion GF0. The second guide roller portion GR2 may extend along the first direction DR1. The third guide roller portion GR3 may be connected to the third clamping member CL3 and arranged on a surface (or upper surface) of the third film portion GF3. The third guide roller portion GR3 may be arranged between the third clamping member CL3 and the main film portion GF0. The third guide roller portion GR3 may extend along the second direction DR2. The fourth guide roller portion GR4 may be connected to the fourth clamping member CL4 and disposed on a surface (or upper surface) of the fourth film portion GF4. The fourth guide roller portion GR4 may be disposed between the fourth clamping member CL4 and the main film portion GF0. The fourth guide roller portion GR4 may extend along the second direction DR2.

[0176] Reference Figure 7 As described above, in an embodiment where the lengths of the respective clamp portions 22 to 25 extending in the extension direction (e.g., the second direction DR2 in the case of the long-side clamp portion and the first direction DR1 in the case of the short-side clamp portion) are the same, the ends of the first edge region to the third edge region of the display panel PN may be aligned with the lower surface 20c of the respective clamp portions 22 to 24, but the peripheral portion of the display panel PN including the end of the fourth edge region and the printed circuit film FPC may protrude further in the lower direction than the lower surface 20c of the second short-side clamp portion 25. In other words, in the thickness direction, a large step difference may occur between the end of the printed circuit film FPC and the lower surface 20c of the second short-side clamp portion 25 of the window clamp 20.

[0177] After the curved window W fixed to the window fixture 20 is brought into contact with the first bonding member AM1 disposed on one surface of the display panel PN, if a predetermined pressure is applied to the upper portion of the window fixture 20 by a laminating device, the main window portion of the curved window W and the main display area DA0 of the display panel PN can be first bonded, and the shape pad SP can be expanded along the outer side of the first direction DR1 (hereinafter, the expansion direction) due to the predetermined pressure applied from the upper portion. The shape pad SP expanded along the first direction DR1 can move the edge region of the display panel PN along the expansion direction, so that each edge region of the display panel PN can be bonded to the corresponding side window portion of the curved window W through the first bonding member AM1.

[0178] However, in the process of combining each edge area of ​​the display panel PN with the corresponding side window portion of the curved window W through the first combining component AM1, the peripheral portion of the end of the display panel PN including the fourth edge area, which is more protruding in the downward direction than the lower surface 20c of the second short side clamp portion 25, and the printed circuit film FPC may be bent in the expansion direction due to the fourth side window portion of the curved window W and the second short side clamp portion 25. Accordingly, the first signal line and the second signal line may be disconnected. The disconnection of the first signal line and the second signal line may cause poor screen driving. In addition, if the printed circuit film FPC that transmits various drive signals to the driver chip IC and / or multiple pixels in each display area of ​​the display panel PN is bent, the various circuit signal lines on the printed circuit film FPC may also be disconnected. The disconnection of various circuit signals on the printed circuit film FPC may cause poor screen driving.

[0179] However, the window fixture composite structure 10 of the manufacturing device 100 of the display device according to an embodiment may include a protective cover 30 covering the end (or lower surface) of the second side window portion of the curved window W and the lower surface 20c of the second short side fixture portion 25 in the thickness direction. The protective cover 30 can support the peripheral portion of the end portion including the fourth edge area of ​​the display panel PN and the printed circuit film FPC that protrude more than the lower surface 20c of the second short side fixture portion 25 in the lower direction on the outside (for example, in the expansion direction). More specifically, the protective cover 30 can be combined with the lower surface 20c of the second short side fixture portion 25, so as to play a role in compensating for the step difference between the peripheral portion including the end portion of the fourth edge and / or the printed circuit film FPC and the second short side fixture portion 25.

[0180] Accordingly, in the process of combining the edge areas of the display panel PN with the corresponding side window portions of the curved window W through the first combining component AM1, the peripheral portion of the end portion of the display panel PN including the fourth edge area, which protrudes further in the downward direction than the lower surface 20c of the second short side clamp portion 25, and the printed circuit film FPC can be prevented from bending along the expansion direction by the protective cover 30.

[0181] Therefore, the first signal line and the second signal line can be prevented from being broken due to bending of the peripheral portion including the end portion of the fourth edge area and / or the printed circuit film FPC that transmits various driving signals to the driving chip IC and / or multiple pixels in each display area of ​​the display panel PN, thereby preventing poor screen driving in advance.

[0182] In the following embodiments, the same reference numerals are used for the same components as those in the previously described embodiments, and the description thereof is omitted or simplified.

[0183] A method for manufacturing a display device according to an embodiment involves using Fig.14 as well as Fig.15 The manufacturing device 100 of the display device is a method for bonding a display panel to a curved window. A more detailed description of this will be described in the following content.

[0184] Fig.16 is a flow chart of a method for manufacturing a display device according to an embodiment. Fig.17 , Fig. 20 , Fig. 22 , Fig.24 as well as Fig.26 It is a three-dimensional diagram according to process steps of a method for manufacturing a display device according to an embodiment. Fig.18 , Fig.19 , Fig.21 , Fig.23 , Fig.25 as well as Fig. 27 is a cross-sectional view showing process steps of a method for manufacturing a display device according to an embodiment. Fig.28 3 is a diagram showing a situation in which pressure rises in a main display area adjacent to an edge area of ​​a display panel during a lamination process between a display panel and a curved window.

[0185] First, with Fig.16 , Fig.17 as well as Fig.18 Reference Figure 5 as well as Figure 6 , prepare a manufacturing device 100 for a display device and a display panel PN. The display panel PN may be arranged on a shape pad SP of the manufacturing device 100 for a display device (S10). The display panel PN may be arranged on a guide film GF on the shape pad SP. The main display area DA0 of the display panel PN may be arranged to overlap with the main film portion GF0 of the guide film GF and the shape pad SP, and each edge region may be arranged to overlap with the corresponding film portion GF1 to GF4. The size on the plane of the main film portion GF0 and the size on the plane of the main display area DA0 may be the same as each other. The size on the plane of each film portion GF1 to GF4 may be larger than the size on the plane of each edge region of the display panel PN. Each film portion GF1 to GF4 may be aligned with the boundary of each edge region corresponding to the main display area DA0. The fourth film portion GF4 may cover the fourth edge region, and may cover a portion of the driver chip IC and the printed circuit film FPC arranged in the fourth edge region.

[0186] The release film SF of the guide film GF may be removed between the step of preparing the manufacturing apparatus 100 of the display device and the step of placing the display panel PN on the guide film GF. The display panel PN may be attached to the second bonding part AM2 exposed by removing the release film SF.

[0187] Then, refer to Fig.19 , the third bonding part AM3 may be arranged on the display panel PN. The third bonding part AM3 may represent Figure 7 The first combination part AM1 is the same as the first combination part AM1. Figure 7 The third bonding part AM3 may be formed on the curved window W (refer to Fig. 22 )The area to which the element will be attached.

[0188] Afterwards, with Fig.16 , Fig. 20 as well as Fig.21 Reference Figure 5 as well as Figure 6 The edge regions of the display panel PN are curved (S20).

[0189] The curvature (S20) of each edge region of the display panel PN can be performed using the guide film GF. More specifically, the curved display panel PN can be formed in the following manner: using the guide roller portions GR1 to GR4 respectively connected to the clamps CL1 to CL4 to lower each film portion GF1 to GF4 except the main film portion GF0, thereby bending the edge regions of the display panel PN from the main display area DA0. The region of each film portion GF1 to GF4 from the main film portion GF0 to the corresponding guide roller portion GR1 to GR4 can extend along the third direction (thickness direction) DR3, and the region of each film portion GF1 to GF4 from the guide roller portion GR1 to GR4 to the end portion fixed by the clamps CL1 to CL4 can extend along the second direction DR2 or the first direction DR1.

[0190] According to a method for manufacturing a display device according to an embodiment, a display panel PN is laminated on a curved window (see Fig. 22 Before forming the curved window W, linear deformation is performed to curve the edge regions of the display panel PN, thereby preventing the edge regions of the display panel PN extending in the horizontal direction (the first direction DR1 or the second direction DR2) from contacting the curved window W and causing physical damage.

[0191] Furthermore, each edge region of the display panel PN is curved in advance, so that when the process of attaching the display panel PN to the curved window W described later is performed, each edge region of the display panel PN and the curved window W can be induced to be aligned with each other (see Fig. 22 The bubbles in the third combining component AM3 between the curved window W and the side window part are better discharged to the outside (the outside of the ends of the third combining component AM3 located at the ends of each edge area and / or around the ends of the side window part).

[0192] Then, refer to Fig.16 , Figure 22 to Figure 27 , using the window fixture composite structure 10 to attach the curved window W on the display panel PN with curved edge regions (S30). Using the window fixture composite structure 10 to attach the curved window W on the display panel PN with curved edge regions (S30) may include the following steps: arranging the curved window W on the window fixture composite structure 10; making the curved window W and the display panel PN close to each other; and applying a predetermined pressure on the upper part of the window fixture composite structure 10 using a laminating device.

[0193] First, refer to Fig.16 , Fig. 22 as well as Fig.23 In the step of arranging the curved window W on the window fixture composite structure 10, the curved window W can be fixed by the window fixture 20. The side window portions can be bent and extended from each edge of the main window portion in the thickness direction. The degree (or angle) of bending of each fixture portion 22 to 25 from the main fixture portion 21 can be the same as or smaller than the degree of bending of each side window portion of the curved window W from the main window portion.

[0194] Then, refer to Fig.16 as well as Fig.24 According to one embodiment, the step of bringing the curved window W and the display panel PN into close contact with each other may include the following steps: moving the curved window W fixed to the window fixture composite structure 10 toward the display panel PN along a lower direction (for example, the other side of the third direction DR3).

[0195] In some embodiments, the step of bringing the curved window W and the display panel PN into close contact with each other may include the following steps: when the curved window W fixed to the window clamp composite structure 10 is fixed, the display panel PN is moved toward the curved window W along the upper direction (for example, on the side of the third direction DR3).

[0196] The movement of the display panel PN toward the curved window W in the upper direction (eg, one side of the third direction DR3) may be performed by providing a fluid to the shape pad SP to expand it, but is not limited thereto and may also be performed by raising the table ST connected to a power device.

[0197] In some embodiments, the step of bringing the curved window W and the display panel PN into close contact with each other may include the following steps: while moving the curved window W fixed to the window clamp composite structure 10 toward the display panel PN along a downward direction (for example, the other side of the third direction DR3), the display panel PN is moved toward the curved window W along an upper direction (for example, one side of the third direction DR3).

[0198] like Fig.25As shown, through the step of making the curved window W and the display panel PN close to each other according to an embodiment, the curved window W can be attached to the display panel PN by sandwiching the third combining part AM3.

[0199] Then, refer to Fig.16 , Fig.26 as well as Fig. 27 , may include the step of applying a predetermined pressure on the upper portion of the window clip composite structure 10 using a laminating device LD.

[0200] If a predetermined pressure is applied to the upper portion of the window fixture composite structure 10 by the laminating device LD, the main window portion of the curved window W and the main display area DA0 of the display panel PN can be firstly combined, and the shape pad SP can be expanded along the outer side of the first direction DR (hereinafter, the expansion direction) due to the predetermined pressure applied from the upper portion. The shape pad SP expanded along the first direction DR1 moves the edge area of ​​the display panel PN along the expansion direction, so that each edge area of ​​the display panel PN can be combined with the corresponding side window portion of the curved window W through the third combining part AM3.

[0201] However, in the process of combining each edge area of ​​the display panel PN with the corresponding side window portion of the curved window W through the third combining component AM3, the peripheral portion of the end of the display panel PN including the fourth edge area and the printed circuit film FPC, which protrude further in the downward direction than the lower surface 20c of the second short side clamp portion 25, may bend along the expansion direction due to the fourth side window portion of the curved window W and the second short side clamp portion 25.

[0202] like Figure 5 As shown, since a plurality of first pads connected to the driver chip IC, a first signal line connected to the first pad, a plurality of second pads connected to the printed circuit film FPC, and a second signal line connected to the second pad are arranged in the fourth edge region of the display panel PN, if the peripheral portion including the end of the fourth edge region is bent, the first signal line and the second signal line may be broken. The breakage of the first signal line and the second signal line may cause poor screen driving. In addition, if the printed circuit film FPC that transmits various driving signals to the driver chip IC and / or multiple pixels in each display area of ​​the display panel PN is bent, the multiple circuit signal lines on the printed circuit film FPC may also be broken. The breakage of multiple circuit signal lines on the printed circuit film FPC may cause poor screen driving.

[0203] However, as described above, the window fixture composite structure 10 according to an embodiment may include a protective cover 30 covering the end (or lower surface) of the second side window portion of the curved window W and the lower surface 20c of the second short side fixture portion 25 in the thickness direction. The protective cover 30 may support the peripheral portion of the end portion of the display panel PN including the fourth edge region and the printed circuit film FPC which are more protruding along the outer side (e.g., expansion direction) than the lower surface 20c of the second short side fixture portion 25 in the lower direction. More specifically, the protective cover 30 may be combined with the lower surface 20c of the second short side fixture portion 25, so as to compensate for the step difference between the peripheral portion of the end portion including the fourth edge region and / or the printed circuit film FPC and the second short side fixture portion 25.

[0204] Accordingly, in the process of combining each edge area of ​​the display panel PN with the corresponding side window portion of the curved window W through the third combining component AM3, the peripheral portion of the end of the display panel PN including the fourth edge area and the printed circuit film FPC which protrude further in the downward direction than the lower surface 20c of the second short side clamp portion 25 can be prevented from bending along the expansion direction by the protective cover 30.

[0205] Therefore, it is possible to prevent the first signal line and the second signal line from being disconnected due to bending of the peripheral portion including the end portion of the fourth edge area and / or the printed circuit film FPC that transmits various driving signals to the driving chip IC and / or multiple pixels in each display area of ​​the display panel PN, thereby preventing poor screen driving in advance.

[0206] Furthermore, if Fig.28 As shown, the protective cover 30 of the window clamp composite structure 10 according to one embodiment can cover and support the end (or lower surface) of the second side window portion of the curved window W and the lower surface 20c of the second short side clamp portion 25 in the thickness direction as described above, so that the shape pad SP expanded in the expansion direction (for example, the first direction DR1 or the second direction DR2) can be expanded again in the upper direction (for example, the third direction DR3). Accordingly, in the area where the pressure for combining the main display area DA0 of the display panel PN adjacent to each edge area and the main window portion of the curved window W adjacent to each side window portion is not fully applied, the combination force between the main display area DA0 of the display panel PN adjacent to each edge area and the main window portion of the curved window W adjacent to each side window portion can be increased.

[0207] The embodiments of the present invention are described above with reference to the accompanying drawings, but it is understood by those with ordinary knowledge in the technical field to which the present invention belongs that the present invention can be implemented in other specific forms without changing the technical ideas or essential features of the present invention. Therefore, the embodiments described above should be understood to be exemplary in all aspects, rather than restrictive.
