Description

Technical Field

[0001] The present invention relates to a protective component for a display device, a display device including the protective component, and a method for manufacturing the protective component for a display device. Background Art

[0002] The display device is a device for displaying an image, including a display panel such as an organic light-emitting display panel or a liquid crystal display panel. In order to protect the display panel from external impact, the display device may include a protective component such as a window. In particular, the window is widely used in portable electronic devices such as smart phones.

[0003] As the material of the window, a transparent film or glass can be used. Compared with glass, the film is more flexible and therefore suitable for flexible display devices, but it is weak to stab wounds. Compared with the film, the glass is stronger than the film, and can have a predetermined flexibility property when it has a thin film thickness or an ultra-thin film thickness, but it will scatter when broken, so it may stab the user.

Throughout the specification, the same symbol refers to the same constituent element.

[0052] Although the terms first, second, etc. are used to describe various components, each component is certainly not limited to these terms. These terms are only used to distinguish one component from other components. Therefore, the first component mentioned below can also be the second component within the technical concept of the present invention.

[0053] Specific embodiments are described below with reference to the accompanying drawings.

[0054] Figure 1 It is a plan view of a display device involved in one embodiment.

[0055] Reference Figure 1The display device 10 displays a picture or an image through the display area DPA, and various devices including the display area DPA may be included in the display device 10. The display device 10 may include, for example, a smart phone, a portable phone, a desktop PC, a PDA (Personal Digital Assistant), a PMP (Portable Multimedia Player), a television, a game console, a watch-type electronic device, a head-mounted display, a personal computer monitor, a notebook computer, a car navigation system, a car dashboard, a digital camera, a video camera, an external advertising board, an electronic billboard, various medical devices, various inspection devices, various home appliances including the display area DPA such as a refrigerator or a washing machine, an Internet of Things device, etc., but is not limited thereto.

[0056] The display device 10 includes a display area DPA and a non-display area NDA. The display area DPA is an area where a picture is displayed, and the non-display area NDA is an area where a picture is not displayed.

[0057] A plurality of pixels PX may be configured in the display area DPA. The pixel PX is a basic unit of a display screen. The pixel PX may include a red pixel, a green pixel, and a blue pixel, but is not limited thereto. The plurality of pixels PX may be arranged alternately on a plane. For example, the pixels PX may be configured in a row and column direction, but is not limited thereto.

[0058] The non-display area NDA may be configured around the display area DPA. The non-display area NDA may be configured around the display area DPA and surround the display area DPA. In one embodiment, the display area DPA may be formed in a rectangular shape, and the non-display area NDA may be configured on the borders of the four sides of the display area DPA, but is not limited thereto.

[0059] Figure 2 It is along Figure 1 A schematic cross-sectional view taken along line II-II'.

[0060] Reference Figure 2 The display device 10 includes a display panel 200 , a display device protection component 100 disposed on a display surface of the display panel 200 , and a printed layer 170 disposed on the display device protection component 100 .

[0061] The display panel 200 may include not only self-luminous display panels such as an organic light-emitting display panel (OLED), an inorganic light-emitting display panel (inorganic EL), a quantum dot light-emitting display panel (QED), a micro-LED display panel (micro-LED), a nano-LED display panel (nano-LED), a plasma display panel (PDP), a field emission display panel (FED), and a cathode ray display panel (CRT), but may also include light-receiving display panels such as a liquid crystal display panel (LCD) and an electrophoretic display panel (EPD).

[0062] The display device protection member 100 is disposed on the upper portion of the display surface of the display panel 200. Here, the display surface of the display panel 200 refers to a surface from which light is emitted to realize the display of a picture, among one surface and the other surface of the display panel 200. In the case of a double-sided display device 10 or a light-transmitting display device 10 that displays on both surfaces, both surfaces may be display surfaces, and in this case, the display device protection member 100 may be disposed on either or both surfaces.

[0063] The display device protection member 100 may be referred to as a window, a protection glass, a protection film, a cover member, a cover glass, a cover film, a cover sheet, etc. Hereinafter, for convenience of description, the display device protection member 100 is simply referred to as a protection member 100 .

[0064] The protective member 100 may have a larger area than the display panel 200. The display panel 200 completely overlaps the protective member 100 in the thickness direction. The side of the protective member 100 may protrude from the side of the display panel 200 toward the outside. The sides from which the protective member 100 protrudes may be all sides of the display panel 200. For example, in the case where the display panel 200 is in a rectangular shape, the protective member 100 may protrude from both long sides and both short sides of the display panel 200. The distance by which the protective member 100 protrudes from the sides of the adjacent display panel 200 may be different or the same on each side.

[0065] The protection member 100 may be attached to the display panel 200 via a transparent layer 300 such as an optically clear adhesive (OCA) or an optically clear adhesive resin (OCR).

[0066] A printing layer 170 may be disposed on the lower surface of the protective component 100. The printing layer 170 is disposed in the non-display area NDA. The printing layer 170 may be disposed in the frame area of ​​the protective component 100, and may be a frame coating. The printing layer 170 may be at least one of a decorative layer that imparts an aesthetic feeling and an outermost black matrix layer. The printing layer 170 may divide the display area DPA and the non-display area NDA. That is, the inner side edge of the printing layer 170 may become the boundary between the display area DPA and the non-display area NDA. The outer side edge of the printing layer 170 may be aligned with the side surface of the protective component 100, but is not limited thereto, and may also be located on the inner side of the protective component 100. The display panel 200 may overlap with at least a portion of the printing layer 170 in the thickness direction.

[0067] The printed layer 170 may be disposed on the surface of the protective member 100 or inside the protective member 100. The protective member 100 may be composed of multiple layers, and in addition to the outermost layer, a layer located in the middle may be selected as a layer coated with the printed layer 170, which will be described later.

[0068] Although not shown, the display device 10 may further include a touch member. The touch member may be provided as a separate panel or film, and thus disposed between the display device 10 and the protective member 100 or formed directly on the display panel 200 or inside the display panel 200.

[0069] Hereinafter, the above-mentioned protection member 100 will be described in more detail.

[0070] Figure 3 It is a cross-sectional view of a protection component according to an embodiment. Figure 4 It is magnified Figure 3 A magnified image of area A. Figure 5 This is an enlarged view of the vicinity of the boundary between the base material overlapping portion and the outer protruding portion of the protection member according to one embodiment, as viewed from below.

[0071] Reference Figures 3 to 5 The protective component 100 includes a glass substrate 110 and a functional coating 120 disposed on the glass substrate 110 .

[0072] The glass substrate 110 may be in the form of a plate having a predetermined thickness. The glass substrate 110 may have a planar shape substantially similar to the planar shape of the display device 10 to which the protective member 100 is applied. When the display device 10 is rectangular, the planar shape of the glass substrate 110 may also be rectangular.

[0073] The glass substrate 110 includes one surface, another surface, and a side surface SS connecting the one surface and the other surface. The one surface (first surface) and the other surface (second surface) are surfaces facing each other in the thickness direction. Hereinafter, for the sake of convenience, one surface of each component of the protective component 100 is a surface placed in the display direction, referred to as the "upper surface US", and the other surface of each component of the protective component 100 is a surface facing the display panel 200, referred to as the "lower surface BS".

[0074] The glass substrate 110 may include an ultra-thin film (Ultra Thin Glass; UTG) or a thin film glass. Since the glass substrate 110 is composed of an ultra-thin film or a thin film, the glass substrate 110 may have a soft property. That is, the glass substrate 110 may have the property of being bent, curved, folded, and curled. The thickness of the glass substrate 110 may be, for example, in the range of 10 μm to 300 μm. In one embodiment, a glass substrate 110 with a thickness of 30 μm to 80 μm or a thickness of about 50 μm may be used.

[0075] The glass substrate 110 may include soda-lime glass, alkali aluminosilicate glass, borosilicate glass, or lithium aluminosilicate glass.

[0076] The glass substrate 110 may include chemically strengthened glass or thermally strengthened glass in order to have greater strength. Chemical strengthening may be achieved by an ion exchange treatment process in an alkali salt. The ion exchange treatment process may be performed twice or more.

[0077] The strengthened glass substrate 110 may have a stress distribution in the direction from the surface to the depth. For example, the glass substrate 110 may include a compression region CS on the surface and a tension region CT inside. In the strengthened glass substrate 110, the stress is generally the largest on the surface, and the stress decreases as it approaches the inside. The compression depth DOL, which is a point where the stress reaches equilibrium, is defined at the boundary between the compression region CS and the tension region CT.

[0078] The glass substrate 110 may be a glass in a substrate state cut into units and then strengthened. The glass strengthening process forms a compression region CS near the surface. For example, during the ion exchange process, ions of alkali salt and glass are mutually exchanged on the surface, and the exchanged ions diffuse into the interior of the glass while forming a compression region CS of a predetermined depth (i.e., equivalent to DOL). However, if the ion exchange process is performed in a state where the glass substrate 110 is cut into units, ion exchange may be formed through the side surface SS in addition to the upper surface US and the lower surface BS of the glass substrate 110. Therefore, in addition to the vicinity of the upper surface US and the lower surface BS of the glass substrate 110, the compression region CS may also be formed near the side surface SS.

[0079] As the compressed region CS is formed near the surface of the glass substrate 110, the surface of the glass substrate 110 is less likely to be scratched. That is, the surface of the glass substrate 110 can have excellent scratch resistance.

[0080] The functional coating 120 is disposed on the side surface SS and the bottom surface BS of the glass substrate 110. The functional coating 120 protects the glass substrate 110 and, on the other hand, prevents or mitigates scattering when the glass substrate 110 is broken, thereby playing a role in reducing the risk of puncture and the like. The functional coating 120 can play a role in preventing the impact directly applied to the glass substrate 110 in the cutting process for alignment. Furthermore, the functional coating 120 can also have a shock absorbing function for mitigating the impact applied from the outside. The detailed description of this will be described later.

[0081] In one embodiment, the functional coating 120 may be directly formed on the side surface SS and the bottom surface BS of the glass substrate 110. The functional coating 120 may be in contact with the side surface SS and the bottom surface BS of the glass substrate 110. That is, the side surface SS and the bottom surface BS of the glass substrate 110 may be covered by the functional coating 120. In one embodiment, all the side surfaces SS and all areas of the bottom surface BS of the glass substrate 110 may be covered by the functional coating 120.

[0082] The upper surface US of the glass substrate 110 may be exposed without being covered by the functional coating 120. The exposed upper surface US of the glass substrate 110 may become the outer surface in the display direction of the display device 10. In the case of this embodiment, since the glass substrate 110 having a relatively greater strength than the film forms the upper surface US of the protective member 100, the puncture property may be excellent.

[0083] The functional coating 120 may be divided into a substrate overlap portion LAP and an outer protrusion portion NLP according to whether or not it overlaps with the glass substrate 110 in the thickness direction. The substrate overlap portion LAP is a portion located on the lower surface BS of the glass substrate 110 and overlaps with the lower surface BS of the glass substrate 110. The thickness of the substrate overlap portion LAP may be smaller than the thickness of the glass substrate 110. For example, the thickness of the substrate overlap portion LAP may be 0.5 μm to 10 μm.

[0084] The outer protrusion NLP is a portion protruding outward with respect to the side surface SS of the glass substrate 110. The outer protrusion NLP is thicker than the substrate overlap portion LAP. The thickness of the outer protrusion NLP may be substantially equal to the sum of the thickness of the substrate overlap portion LAP and the thickness of the glass substrate 110 overlapped therewith. Meanwhile, even if the impact absorbing pattern PT described later is arranged on the outer protrusion NLP and the impact absorbing pattern PT includes a plurality of grooves GR, the thickness of the impact absorbing pattern PT of the functional coating 120 located between the plurality of grooves GR may be substantially equal to the sum of the thickness of the substrate overlap portion LAP and the thickness of the glass substrate 110 overlapped therewith.

[0085] The outer protrusion NLP may include an impact absorbing pattern PT. The impact absorbing pattern PT may perform a function of alleviating an impact applied from the outside. The impact absorbing pattern PT may be formed across the entire area of ​​the outer protrusion NLP of the functional coating 120. The impact absorbing pattern PT formed by the plurality of grooves GR may overlap the entire area of ​​the outer protrusion NLP of the functional coating 120. That is, the plurality of grooves GR forming the impact absorbing pattern PT may be formed across the entire area of ​​the outer protrusion NLP of the functional coating 120. In addition, the plurality of grooves GR may not overlap the glass substrate 110 in the thickness direction.

[0086] The impact absorption pattern PT may include a plurality of grooves GR that are recessed from the lower surface BS of the outer protrusion NLP of the functional coating 120 toward the upper surface US of the outer protrusion NLP. That is, at least one of the upper surface US and the lower surface BS of the outer protrusion NLP may include a concave-convex surface in at least a portion of the area. The impact absorption pattern PT located at the outer protrusion NLP of the functional coating 120 may include a plurality of grooves GR surrounded by the functional coating 120, and the grooves GR may be located at the lower surface BS of the outer protrusion NLP of the functional coating 120. However, it is not limited to this, and the plurality of grooves GR forming the impact absorption pattern PT may also be formed in a form that is recessed from the upper surface US of the outer protrusion NLP toward the lower surface BS while being located on the upper surface US of the outer protrusion NLP. The interior of the groove GR forming the impact absorption pattern PT may be an empty space. However, it is not limited to this, and the interior of the groove GR may also be filled with a substance that absorbs the impact applied from the outside to mitigate the impact.

[0087] Although the plurality of grooves GR forming the impact absorbing pattern PT are formed in a triangular shape, the shape of the grooves GR is not limited thereto and may be formed in various shapes, such as a rectangular shape or a circular shape that is recessed from the lower surface toward the upper surface.

[0088] As the outer protrusion NLP includes the impact absorbing pattern PT, the impact applied from the outside can be mitigated, thereby suppressing or preventing the glass substrate 110 from being damaged. In detail, the outer protrusion NLP of the functional coating 120 covers the side of the glass substrate 110, and the impact applied from the outside of the protective member 100, especially the impact applied from the side, is not directly applied to the glass substrate 110, but can be applied to the functional coating 120 first. In this case, the impact absorbing pattern PT including the groove GR formed by an empty space or filled with a substance that can absorb the impact can reduce the impact applied from the outside, so it is possible to prevent or suppress damage or breakage of the glass substrate 110 caused by the external impact.

[0089] The upper surface US of the functional coating 120 and the upper surface US of the glass substrate 110 may be connected without any height difference. In one embodiment, the upper surface US of the functional coating 120 may be at the same level as the upper surface US of the glass substrate 110, and may be located on substantially the same plane or on an extension surface of the upper surface US of the glass substrate 110. The lower surface BS of the functional coating 120 may be parallel to at least one of the upper surface US of the functional coating 120 and the upper surface of the glass substrate 110, and may also be substantially parallel to the lower surface BS of the glass substrate 110.

[0090] The outer side SS (or side) of the functional coating 120 may connect the upper surface US of the functional coating 120 and the lower surface BS of the functional coating 120. The outer side SS of the functional coating 120 may connect the upper surface US of the outer protrusion NLP and the lower surface BS of the outer protrusion NLP.

[0091] The outer side surface SS of the functional coating 120 may be located on the same plane as the thickness direction. That is, the outer side surface SS of the functional coating 120 may be perpendicular to the lower surface BS of the glass substrate 110 (or the lower surface BS of the functional coating 120) and the upper surface US of the functional coating 120. At the same time, the outer side surface SS of the functional coating 120 may be perpendicular to the upper surface US of the glass substrate 110. The outer side surface SS of the functional coating 120 and the side surface SS of the glass substrate 110 opposite thereto may be parallel, but are not limited thereto. The width of the functional coating 120 protruding from the side surface SS of the glass substrate 110 may be 1 μm to 100 μm, but is not limited thereto. The outer side surface SS of the functional coating 120 may be a cut surface obtained by a laser cutting process (refer to Fig.11 That is, the outer side surface SS of the functional coating 120 may be, for example, a laser cut surface.

[0092] The functional coating 120 may be formed to include a resin. For example, the functional coating 120 may include at least one of epoxy acrylate resin, polyester acrylate resin, polyether acrylate resin, urethane acrylate resin, acrylic acrylate resin, unsaturated polyester, urethane resin, acrylonitrile-butadiene-styrene (ABS) resin, and rubber. In several embodiments, the functional coating 120 may also be applied to organic-inorganic hybrid type substances.

[0093] A printed layer 170 may be disposed on the lower surface BS of the functional coating 120 . The printed layer 170 may be aligned with the outer side surface SS of the functional coating 120 , and cover the outer protrusion NLP of the functional coating 120 and extend inwardly thereof, thereby partially overlapping the substrate overlap portion LAP of the functional coating 120 .

[0094] As described above, the side surface SS of the glass substrate 110 of the present embodiment is not directly exposed to the outside, but is covered and protected by the functional coating 120. The side surface SS of the protective component 100 is formed by the side surface SS of the functional coating 120, and the side surface SS of the glass substrate 110 does not constitute the side surface SS of the protective component 100. Therefore, the side surface SS of the protective component 100 does not have a separate protruding structure, so that the assembly tolerance can be minimized. The detailed description of this will be given in Figure 6 The embodiments are described later.

[0095] On the other hand, although not shown in the figure, Figure 3 The protective component 100 may be stacked in two or more layers. The protective components 100 stacked in two or more layers may be respectively located at the same positions as the glass substrate 110 and the functional coating 120 in the thickness direction. In this case, each protective component 100 stacked in two or more layers may be a glass substrate 110 and a functional coating 120 that are sequentially repeated in the thickness direction. However, this is not limited to this, and part of the protective component 100 may be stacked in a state where the positions of the glass substrate 110 and the functional coating 120 in the thickness direction are replaced. For example, in a state where two or more layers of the protective component 100 are stacked, part of the protective component 100 may be a glass substrate 110 that is in direct contact with the glass substrate 110 or a functional coating 120 that is in direct contact with the functional coating 120. That is, there is no limit to the number of layers of the stacked protective component 100, and part of the protective component 100 may be stacked in a state where the upper surface US and the lower surface BS in the figure are reversed.

[0096] Meanwhile, the protective component 100 may further include a front surface coating disposed on the upper surface US of the glass substrate 110. The front surface coating may perform one or more functions of anti-reflection, anti-fingerprint, antibacterial, blue light blocking, electromagnetic wave shielding, privacy, etc. The front surface coating may be wet-coated using a fluorine-based coating liquid or dry-coated by vacuum deposition, but is not limited thereto.

[0097] Figure 6 It is a cross-sectional view of a protective component according to another embodiment.

[0098] Reference Figure 6 The protection component 100_1 of this embodiment and Figure 3 The difference between the embodiments of the present invention lies in that it further includes other layers stacked on the lower surface BS of the functional coating layer 120.

[0099] Specifically, the bonding layer 130 is disposed on the lower surface BS of the functional coating layer 120 , and the film layer 140 is disposed on the lower surface BS of the bonding layer 130 .

[0100] The bonding layer 130 is between the functional coating 120 and the film layer 140 and plays the role of bonding the functional coating 120 to the film layer 140. Preferably, the bonding layer 130 is an adhesive layer, but it can also be an adhesive layer. The bonding layer 130 can have a minimum adhesive force / adhesion force of 500gf / in at room temperature (25°C) and 50% humidity conditions so that at least one of the functional coating 120 and the glass substrate 110 will not peel off from the display panel 200 side. In addition, in order to resist external impact and ensure the resilience to deformation, it can have a storage modulus of about 80MPa to about 120MPa under the conditions. At the same time, the bonding layer 130 can have a predetermined creep property for relieving stress when folded or bent, and can have a creep property of 50% to 800% under the conditions. The bonding layer 130 may include any one of acrylic resin, silicon resin, epoxy resin, urethane resin, or a composite resin thereof.

[0101] The film layer 140 bonded to the lower surface BS of the glass substrate 110 through the bonding layer 130 can perform an anti-scattering function. For example, even if the glass substrate 110 is broken, the fragments will adhere to the film layer 140, so the fragments can be prevented from scattering. In addition to the anti-scattering function or on the basis of the anti-scattering function, the film layer 140 also performs other functions such as an impact resistance mitigation function.

[0102] In the case where the film layer 140 includes an anti-scattering film, the film layer 140 may include a transparent polymer resin. The transparent polymer resin constituting the film layer 140 may include at least one of PET (PolyEthylene Terephthalate), PEN (PolyEthylene Naphthalate), PES (Polyether Sulfone), PI (PolyImide), PAR (PolyARylate), PC (PolyCarbonate), PMMA (PolyMethyl MethAcrylate) and COC (CycloOlefinCopolymer).

[0103] The film layer 140 and the bonding layer 130 have a width greater than that of the glass substrate 110 and protrude outward from the side surface SS of the glass substrate 110. The side surfaces SS of the film layer 140 and the bonding layer 130 can be aligned with the side surfaces SS of the functional coating 120. That is, the functional coating 120, the bonding layer 130, and the side surfaces SS of the film layer 140 can be aligned with the alignment plane AGL or the alignment line of the straight line shape on the cross section. The side surfaces SS of the film layer 140 and the bonding layer 130 can be cut surfaces (see FIG. 1 ) in the same manner as the side surfaces SS of the functional coating 120 described above. Fig.11 of "CTL").

[0104] The protection component 100_1 may further include a printed layer 170. In the case of the printed layer 170, the outer side surface SS may be aligned with the alignment plane AGL, but the present invention is not limited thereto. Figure 6 In the embodiment of the present invention, the printed layer 170 is different from Figure 3 The embodiment of FIG. 1 shows the case where the printed layer 170 is disposed on the lower surface BS of the film layer 140. However, the printed layer 170 may also be disposed at other positions in the thickness direction. For example, Figure 6 In the embodiment of the present invention, the printed layer 170 may also be formed on the lower surface BS of the functional coating 120. In this case, the printed layer 170 may be between the functional coating 120 and the bonding layer 130. As another example, the printed layer 170 may also be formed across the upper surface US of the functional coating 120 and the upper surface US of the glass substrate 110 or formed on the upper surface US of the film layer 140. In addition, a plurality of printed layers 170 may also be configured to at least partially overlap at different positions in the thickness direction.

[0105] As described above, the protective component 100_1 according to an embodiment of the laminated structure in which the glass substrate 110 and the film layer 140 are bonded has a structure in which the film layer 140 protrudes outward from the side surface SS of the glass substrate 110, but when the protective component 100_1 is viewed as a whole, the side surfaces SS of the functional coating 120, the bonding layer 130, and the film layer 140 constituting the side surface SS thereof are aligned with each other without protrusion. Therefore, when the protective component 100_1 is attached to the display panel 200 and they are set in the kit (housing or bracket, etc.) of the display device 10, the assembly tolerance can be minimized, so the process capability and process efficiency can be improved. In addition, the glass substrate 110 is protected by the functional coating 120, the bonding layer 130, the film layer 140, etc., and the impact resistance characteristics can be improved, and when the glass substrate 110 is broken, the fragments can be prevented from flying.

[0106] Although not shown, Figure 6 The protective member 100_1 may include at least one of a plurality of bonding layers 130 and a plurality of film layers 140. For example, a plurality of bonding layers 130 and a plurality of film layers 140 may be disposed under one glass substrate 110 and a functional coating 120, or one or more bonding layers 130 and one or more film layers 140 may be disposed between a plurality of glass substrates 100 and a plurality of functional coatings 120.

[0107] The structure in which the impact absorption pattern PT and the side surface SS of the outer protrusion NPL located at the functional coating 120 are aligned without protrusion can be obtained by a cutting process after laminating each layer in the manufacturing process of the protective member 100_1. The cut surface is not in direct contact with the glass substrate 110 but is located outside thereof, so that the impact generated in the cutting process can be minimized from being transmitted to the glass substrate 110.

[0108] Meanwhile, for the side surface of the functional coating 120 (or the cut surface of the functional coating 120 (refer to Fig.11 CTL) can repair cracks that may occur on the cutting surface by laser sintering. Fig.11 Thus, the impact resistance of the protection component 100_1 can be enhanced.

[0109] In order to explain the manufacturing method of the protective component, the following will refer to Figures 7 to 12 .

[0110] Figures 7 to 11 According to the process steps Figure 6 A cross-sectional view of a method for manufacturing a protective component. Fig.12 1 is a diagram showing a process of repairing a crack CR in a functional coating layer by a repairing step of the functional coating layer.

[0111] First, refer to Figure 7 and Figure 8 , a glass substrate 110 is placed on a workbench 500. Then, a functional composition 120a is applied to the lower surface BS (the surface facing upward in the figure) of the glass substrate 110. The functional composition 120a may include a liquid resin. Figure 6 In the process of forming the protective member 100_1, the method of coating the functional composition 120a is described as a glass direct molding (GDM) method, but the method of coating the functional composition 120a is not limited thereto. The method of coating the functional composition 120a can be coated by methods such as slit coating, rod coating, spin coating, glass direct printing (GDP), etc.

[0112] During the coating of the functional composition 120a, a bar roller 400 may be used. The bar roller 400 may include a first bar region 410 and a second bar region 420. The first bar region 410 may be a region surrounded by a flat surface without protrusions, and the second bar region 420 may be a region including a plurality of protrusions on the surface.

[0113] The first rod region 410 may be located between the two second rod regions 420. That is, the first rod region 410 may be located near the center of the roller 400, and the second rod region 420 may be located near both ends of the roller 400. The first rod region 410 may correspond to the substrate overlapping portion LAPa of the functional composition 120a, and the second rod region 420 may correspond to the outer protruding portion NLPa of the functional composition 120a.

[0114] As the functional composition 120a is applied using the roller 400, a plurality of grooves may be formed on the outer protrusion NLPa of the functional composition 120a. Then, the functional composition 120a is cured and a cutting process is performed to form a shock absorbing pattern PT on the outer protrusion NLP of the functional coating 120, which will be described later.

[0115] After the functional composition 120a is coated on the lower surface BS of the glass substrate 110, the coated functional composition 120a may be cured. The curing process may be performed by thermal curing or ultraviolet curing. The functional composition 120a may be cured to form a functional coating 120 (see Fig. 9 ). The functional coating 120 formed after the functional composition 120a is cured (refer to Fig. 9) Its lower surface BS (the surface facing upward in the figure) is flat and can completely cover the lower surface BS and the side surface SS of the glass substrate 110. The functional coating 120 can protrude from the side surface SS of the glass substrate 110 by a corresponding distance. The outer side surface SS of the functional coating 120 in this step can also have an acute angle of inclination, but is not limited thereto.

[0116] Then, refer to Fig. 9 , a bonding layer 130 and a film layer 140 are stacked on the lower surface BS of the functional coating 120. The stacking can be achieved by laminating the functional coating 120 in a state where the bonding layer 130 is already bonded to the film layer 140. As another example, the bonding layer 130 can be first coated or laminated on the functional coating 120, and the film layer 140 can be arranged on top thereof to form the stacked structure. The printed layer 170 can be formed on the film layer 140 after the film layer 140 is stacked, or the printed layer 170 can be first formed on the film layer 140 and then the film layer 140 is stacked to form the structure as shown in FIG. Figure 6 The stacked structure shown.

[0117] The width of the bonding layer 130 and the film layer 140 may be greater than the width of the glass substrate 110, and may protrude from the side surface SS of the glass substrate 110. The positional relationship between the side surfaces SS of the functional coating 120, the bonding layer 130, and the film layer 140 may have various modifications. The example shown in the figure is a case where the functional coating 120 protrudes most outward and the film layer 140 protrudes relatively more outward than the bonding layer 130, but their side surfaces SS may also be aligned with each other, and the protrusion relationship may also be changed to be different from the example shown in the figure.

[0118] Reference Fig.10 , cutting Fig. 9 The portion to be cut is the frame portion of the stacked structure, which is further outward than the side surface SS of the glass substrate 110. The cutting process is a process of cutting the film layer 140, the bonding layer 130 and the functional coating 120 together, and they are partially cut respectively, but the glass substrate 110 is not cut. The cutting can be achieved by irradiation with the cutting laser LAS_C, but is not limited to this, and can also be achieved by cutting based on a knife or based on other cutting components.

[0119] The side surface SS of the cut protection member 100_1 may become a cut surface based on the cutting process (see Fig.11 In addition, even if the side surface SS of the functional coating 120 before cutting has an acute inclination, the side surface SS of the functional coating 120 after cutting can also have an angle perpendicular to the upper surface US and the lower surface BS.

[0120] As shown in the above example, when the functional coating 120 located outside the glass substrate 110 is cut, the impact is not directly transmitted to the glass substrate 110. In addition, since the glass substrate 110 itself is not cut, the compressed area CS located near the surface of the side surface SS of the glass substrate 110 can be maintained without any change. Therefore, by the above method, the protective member 100_1 aligned with the side surface SS can be formed without losing the strength of the glass substrate 110.

[0121] At the same time, in the case of the printed layer 170 , it can also be cut in this step, and the outer side surface SS of the printed layer 170 will also be aligned with the side surface SS of the functional coating 120 , the bonding layer 130 and the film layer 140 .

[0122] Although not shown, I want to make Figure 3 In the case of the protective component 100 of the embodiment, the Fig. 9 The cutting step is performed directly after the functional coating 120 is formed.

[0123] Reference Fig.11 and Fig.12 , repaired by laser sintering Fig.10 The functional coating 120 is cut, so that the following can be accomplished: Figure 6 The protective component 100_1 is shown.

[0124] Specifically, the repair laser LAS_R may be irradiated to the entire area of ​​the cut surface CTL of the functional coating 120. On the cut surface CTL of the functional coating 120 irradiated with the repair laser LAS_R, a partial area of ​​the functional coating 120 may be recrystallized. Thus, the crack CR that may be generated on the cut surface CTL of the functional coating 120 may be removed. That is, if the repair laser LAS_R is irradiated to a partial area of ​​the functional coating 120 located around the crack CR generated on the cut surface CTL of the functional coating 120, the partial area may be recrystallized by the repair laser LAS_R, thereby removing the crack CR.

[0125] By removing the cracks CR generated on the cut surface CTL of the functional coating 120 , it is possible to suppress or prevent the reduction in the impact resistance of the protection member 100 , 100_1 that may be caused by the generation of the cracks CR.

[0126] However, the above-mentioned step of repairing the functional coating 120 can be omitted, and the above-mentioned step of cutting the stacked structure can be performed. Figure 6 The protective component 100_1 is shown.

[0127] In the following embodiments, the same configurations as those in the previously described embodiments are omitted or simplified, and the differences are mainly described.

[0128] Fig.13 is a cross-sectional view of a protective component according to still another embodiment.

[0129] Reference Fig.13 The impact absorption pattern PT_2 of the protection component 100_2 of this embodiment is Figure 3 The difference of the embodiment is that it is only configured on a part of the outer protrusion NLP.

[0130] Specifically, the protection component 100_2 of the present embodiment includes a shock absorbing pattern PT_2, but the shock absorbing pattern PT_2 is not arranged in the entire area of ​​the outer protrusion NLP, but can be arranged only in a partial area of ​​the outer protrusion NLP. That is, the plurality of grooves GR forming the shock absorbing pattern PT_2 can be arranged only in a partial area of ​​the outer protrusion NLP.

[0131] In this case, since the outer protrusion NLP includes the impact absorbing pattern PT_2, the impact applied from the outside, especially the impact applied from the side of the functional coating 120, can be mitigated, and the damage or breakage of the glass substrate 110 due to the external impact can be suppressed or prevented.

[0132] Fig.14 is a cross-sectional view of a protective component according to still another embodiment. Fig.15 It is magnified Fig.14 Magnified view of area B.

[0133] Reference Fig.14 and Fig.15 The impact absorption pattern PT_3 of the protection component 100_3 of this embodiment is Figure 3 The embodiment of FIG. 1 is different in that the groove GR is not included but a hole HLE is included.

[0134] Specifically, the protective component 100_3 involved in this embodiment includes an impact absorption pattern PT_3 in the outer protrusion NPL of the functional coating 120, but the impact absorption pattern PT_3 may include a plurality of holes HLE. The plurality of holes HLE may be surrounded by the functional coating 120 and may penetrate the functional coating 120 in the thickness direction. The cross-sectional view shows that the plurality of holes HLE have a certain diameter, but it is not limited to this, and the plurality of holes HLE may be formed in various shapes. For example, the diameter of the plurality of holes HLE in the cross-sectional view may gradually increase, or gradually decrease, or gradually increase and then decrease from the upper surface US of the functional coating 120 toward the lower surface BS. The plurality of holes HLE may be formed as an empty space inside, or may be filled with a material that can absorb the impact applied from the outside to mitigate the impact.

[0135] In addition, the thickness of the outer protrusion portion NPL of the functional coating 120 between the plurality of holes HLE may be substantially equal to the sum of the thickness of the substrate overlapping portion LAP and the thickness of the glass substrate 110 overlapping therewith.

[0136] Meanwhile, in the figure, the functional coatings 120 between the holes HLE appear to be separated from each other, but the holes HLE are dispersedly arranged on the outer protrusions NPL of the functional coating 120 , and the functional coatings 120 between the holes HLE, especially the outer protrusions NPL, are connected to each other.

[0137] In this case, the outer protrusion NLP includes the impact absorbing pattern PT_3, so that the impact applied from the outside, especially the impact applied from the side of the functional coating 120, can be alleviated, and the glass substrate 110 can be suppressed or prevented from being damaged or broken due to the external impact.

[0138] Fig.16 is a cross-sectional view of a protective component according to still another embodiment. Fig.17 It is magnified Fig.16 Magnified view of region C.

[0139] Reference Fig.16 and Fig.17 The impact absorption pattern PT_4 of the protection component 100_4 of this embodiment is Figure 3 The embodiment of FIG. 1 is different in that the outer protrusion NLP of the functional coating 120 is formed in a sponge-like shape.

[0140] Specifically, the protection component 100_4 involved in this embodiment includes a shock absorbing pattern PT_4, which can be formed into a sponge-like shape while being arranged on the outer protrusion NLP of the functional coating 120. The outer protrusion NLP of the functional coating 120 can be at least partially formed into a sponge-like shape. That is, at least a portion of the outer protrusion NLP can include a plurality of empty spaces surrounded by the functional coating inside.

[0141] In this case, the outer protrusion NLP includes the impact absorbing pattern PT_4, so that the impact applied from the outside, especially the impact applied from the side of the functional coating 120, can be alleviated, and the glass substrate 110 can be suppressed or prevented from being damaged or broken due to the external impact.

[0142] Fig.18 is a cross-sectional view of a protection component according to still another embodiment.

[0143] Reference Fig.18 The impact absorbing pattern PT_5 of the protection component 100_5 of this embodiment is Figure 3 The embodiment of FIG. 1 is different from that of FIG. 2 in that it includes both the groove GR and the hole HLE.

[0144] Specifically, the protection component 100_5 involved in this embodiment may include a shock absorbing pattern PT_5 in the outer protrusion NLP, and the shock absorbing pattern PT_5 may include a plurality of grooves GR and a plurality of holes HLE. That is, the plurality of grooves GR and the plurality of holes HLE may be arranged across the entire area of ​​the outer protrusion NLP of the functional coating 120. The plurality of grooves GR and the plurality of holes HLE may be arranged sequentially, but are not limited thereto, and may also be arranged randomly.

[0145] In this case, the outer protrusion NLP includes the impact absorbing pattern PT_5, so that the impact applied from the outside, especially the impact applied from the side of the functional coating 120, can be alleviated, and the glass substrate 110 can be suppressed or prevented from being damaged or broken due to the external impact.

[0146] Fig.19 is a cross-sectional view of a protection component according to still another embodiment.

[0147] Reference Fig.19 The impact absorption pattern PT_6 of the protection component 100_6 of this embodiment is Fig.18 The difference of the embodiment is that the outer protrusion NLP disposed outside the one side surface SS of the glass substrate 110 includes a plurality of grooves GR, and the outer protrusion NLP disposed outside the other side surface SS of the glass substrate 110 includes a plurality of holes HLE.

[0148] Specifically, the shock absorbing pattern PT_6 involved in this embodiment may include a first pattern PT_6a and a second pattern PT_6b. The first pattern PT_6a may be arranged outside one side surface SS of the glass substrate 110, and the second pattern PT_6b may be arranged outside the other side surface SS of the glass substrate 110. The first pattern PT_6a may include only a plurality of grooves GR, and the second pattern PT_6b may include only a plurality of holes HLE. That is, the shock absorbing pattern PT_6 involved in this embodiment may include a first pattern PT_6a and a second pattern PT_6b, and the first pattern PT_6a and the second pattern PT_6b may be formed by patterns different from each other.

[0149] In this case, the outer protrusion NLP includes the impact absorbing pattern PT_6, so that the impact applied from the outside, especially the impact applied from the side of the functional coating 120, can be alleviated, and the glass substrate 110 can be suppressed or prevented from being damaged or broken due to the external impact.

[0150] Fig. 20 It is a partial cross-sectional view of a protection component according to still another embodiment.

[0151] Reference Fig. 20 The protection component 100_7 of this embodiment and Figure 3 The difference between the embodiment of the present invention is that the corner (the part where two or more surfaces intersect) EDG of the glass substrate 110_7 is inclined. That is, the glass substrate 110_7 can be processed into the following shape, that is, after cutting a certain substrate state of glass into units, the corresponding part is processed into a flat or curved shape by grinding or cutting to prevent the corner from being damaged. The corner surface EDG has substantially obtuse angles θ1 and θ2 with respect to the adjacent surfaces (the upper surface US and the side surface SS in the figure).

[0152] However, in this case, the functional coating 120 covers the corner surface EDG of the glass substrate 110_7 but does not reflect its shape. That is, the side surface SS of the functional coating 120 may be formed by cutting and may have a perpendicular angle with respect to the upper surface US and the lower surface BS.

[0153] Fig. 20 The glass substrate 110_7 can be Figures 3 to 19 The glass substrate 110 is shown being replaced.

[0154] Fig.21 is a cross-sectional view of a protection component according to still another embodiment.

[0155] Reference Fig.21 The protection component 100_8 involved in this embodiment and Figure 6The difference between the embodiments is that the functional coating 120_8 is only disposed on the side surface SS of the glass substrate 110.

[0156] Specifically, the functional coating 120_8 is disposed on a plane at a frame portion of the glass substrate 110, and does not overlap with the glass substrate 110 in a thickness direction. The upper surface US of the functional coating 120_8 may be substantially located on the same plane as the upper surface US of the glass substrate 110, and the lower surface BS of the functional coating 120_8 may be substantially located on the same plane as the lower surface BS of the glass substrate 110. The thickness of the functional coating 120_8 may be substantially the same as the thickness of the glass substrate 110. The lower surface BS of the glass substrate 110 is not covered by the functional coating 120_8 but is exposed, and the bonding layer 130 is attached to the lower surface BS of the functional coating 120_8 and the lower surface BS of the glass substrate 110.

[0157] In this case, the side surface SS of the protective member 100_8 is composed of the functional coating layer 120_8, the bonding layer 130 and the film layer 140, which can be aligned with each other. Therefore, when the protective member 100_8 is attached to the display panel 200 and they are set in the kit of the display device 10, the assembly tolerance can be minimized and the process efficiency can be improved.

[0158] At the same time, since the outer protrusion NLP includes the impact absorbing pattern PT, the impact applied from the outside, especially the impact applied from the side of the functional coating 120_8, can be mitigated, and the glass substrate 110 can be suppressed or prevented from being damaged or broken due to the external impact.

[0159] Hereinafter, each of the above-mentioned embodiments will be described in further detail through manufacturing examples and experimental examples.

[0160] <Production Example 1>

[0161] A protective component having a structure in which a glass substrate having a thickness of 30 μm was directly bonded to a film layer using a bonding layer without a functional coating was manufactured.

[0162] <Production Example 2>

[0167] A weight drop test was performed on the protection members of Manufacturing Examples 1 and 2 and Comparative Example 1. The weights were dropped on the protection members at different heights in centimeters to determine the height at which the protection members were broken or punctured.

[0168] The results of Experimental Example 1 are recorded in Table 1 below.

[0170]

[0171]

[0172] Referring to Table 1, it was confirmed that the impact resistance of Comparative Example 1 including the impact absorbing pattern was improved compared with that of Manufacturing Examples 1 and 2 not including the impact absorbing pattern. That is, in the case of Manufacturing Example 1, it was crushed at a height of 5 cm, and in the case of Manufacturing Example 2, it was crushed at a height of 15 cm. In the case of Comparative Example 1 including the impact absorbing pattern, it was crushed at a height of 30 cm, which was higher than that of Manufacturing Examples 1 and 2. Therefore, it was confirmed that Comparative Example 1 had extremely excellent impact resistance compared with Manufacturing Examples 1 and 2.
