[0084] According to one embodiment, the window (201b) may be coupled with the edge part (218). For example, the window (201b) may include an outer portion extending outside the display (201) when viewed in the z-axis direction, and may be adhered to the edge part (218) through an adhesive member (e.g., waterproof tape) disposed between the outer portion of the window (201b) and the edge part (218). However, the present invention is not limited to the above-described example.

According to one embodiment, the first printed circuit board (251) and the second printed circuit board (252) may be operatively or electrically connected to each other via a connecting member (e.g., a flexible printed circuit board).
[0086] In one embodiment, a battery (270) (e.g., battery (189) of FIG. 1 ) may power at least one component of the electronic device (101). For example, the battery (270) may include a rechargeable secondary battery or a fuel cell.

[0088] According to one embodiment, a first camera module (205) (e.g., a front camera) may be positioned on at least a portion of the bracket (243) such that the lens can receive external light through a portion (e.g., the camera area (237)) of the window (201b) (e.g., the front (200A) of FIG. 2).
[0089] In one embodiment, a second camera module (212) (e.g., a rear camera) may be disposed between the bracket (243) and the cover plate (211). In one embodiment, the second camera module (212) may be electrically connected to the first printed circuit board (251) via a connecting member (e.g., a connector). In one embodiment, the second camera module (212) may be disposed such that a lens can receive external light through the camera area (284) of the cover plate (211) of the electronic device (101).
[0090] According to one embodiment, the camera area (284) may be formed on a surface of the cover plate (211) (e.g., the rear surface (200B) of FIG. 2). According to one embodiment, the camera area (284) may be formed to be at least partially transparent so that external light may be incident on the lens of the second camera module (212). According to one embodiment, at least a portion of the camera area (284) may protrude from the surface of the cover plate (211) by a predetermined height. However, the present invention is not limited thereto, and according to one embodiment, the camera area (284) may form a plane substantially identical to the surface of the cover plate (211).
[0091] According to one embodiment, the housing assembly (210) of the electronic device (101) may refer to a configuration or structure that forms at least a portion of the exterior of the electronic device (101). In this respect, at least a portion of the window (201b), the edge part (218), the bracket (243), and / or the cover plate (211) that form the exterior of the electronic device (101) may be referred to as the housing assembly (210) of the electronic device (101).
[0092] An electronic device (101) according to one embodiment may include a cover plate (211). The cover plate (211) may define at least a portion of a rear surface (e.g., a second surface (200B) of FIG. 2) of the electronic device (101). The cover plate (211) may be referred to as a rear cover or a back cover in terms of defining at least a portion of the rear surface of the electronic device (101). For example, the cover plate (211) may be opposite a display (or a window (201b) of the display) that forms at least a portion of a front surface (e.g., a first surface (200A) of FIG. 2) of the electronic device (101). The window (201b) of the display (201) may form at least a portion of the front surface of the electronic device (101), and the cover plate (211) may form at least a portion of the rear surface of the electronic device (101). The display can be oriented substantially in the +z direction, and the cover plate (211) can be oriented substantially in the -z direction.
[0093] Fig. 4a illustrates a cover plate of an electronic device according to one embodiment. Fig. 4b is a cross-sectional view taken along line A-A' of Fig. 4a of the cover plate according to one embodiment. Fig. 4c illustrates a plurality of lenticular-type patterns. Fig. 4d illustrates a plurality of prism-type patterns.
[0094] Referring to FIG. 4A, the cover plate (211) may have a rectangular shape. That the cover plate (211) has a rectangular shape may indicate that the cover plate (211) includes edge portions corresponding to the long side (211a) and the short side (211b) of the rectangle. The edge portions of the cover plate (211) may be at least partially rounded, but the shape of the cover plate (211) may correspond to an approximate rectangle.
[0095] According to one embodiment, the cover plate (211) can be viewed by a user because it is exposed to the outside of the electronic device (e.g., the electronic device (101) of FIG. 2). The cover plate (211) can enhance the aesthetic quality of the electronic device (101) by utilizing reflection and / or refraction of light. When light is reflected and / or refracted, interference effects and prism effects of light can be caused. For example, when a user looks at the cover plate (211), light reflected and / or refracted by the cover plate (211) can cause a unique and sophisticated visual effect.
[0096] Referring to FIG. 4B, the cover plate (211) may include a film (420) for causing reflection and / or refraction of light. The film (420) may include a plurality of patterns (440) for causing reflection and / or refraction of light. The plurality of patterns (440) may enhance the aesthetic quality of the cover plate (211) by causing various optical effects on the surface of the cover plate (211). From the perspective of utilizing the optical effect, the film (420) may be referred to as an optical film or a decorative film, and the plurality of patterns (440) may be referred to as optical patterns. The plurality of patterns (440) may be formed by repeating patterns having a certain shape. According to one embodiment, the plurality of patterns (440) may be formed by repeating patterns having a linear shape. According to one embodiment, the plurality of patterns (440) may be formed by repeating patterns having a curved shape. According to one embodiment, the plurality of patterns (440) may include curved patterns.
[0097] According to one embodiment, the cover plate (211) may include a base plate (410) and a film (420).
[0098] According to one embodiment, the base plate (410) may be disposed at the outermost portion of the cover plate (211) and may be exposed to the outside of the electronic device (e.g., the electronic device (101) of FIG. 2). The base plate (410) may include a front surface (410a) that is exposed to the outside of the electronic device (101) and a back surface (410b) opposite to the front surface (410a). The front surface (410a) of the base plate (410) may at least partially define the back surface (e.g., the second surface (200B) of FIG. 2) of the electronic device (101). The back surface (410b) of the base plate (410) may face the inside of the electronic device (101). For example, the front surface (410a) of the base plate (410) may face the +z direction, and the back surface (410b) of the base plate (410) may face the -z direction.
[0099] According to one embodiment, the base plate (410) may be referred to as a substrate that defines the basic shape of the cover plate (211). The base plate (410) may be substantially transparent. For example, the base plate (410) may be formed from a glass material, or may be formed from a transparent or translucent synthetic resin material. For example, when light is incident on the substantially transparent or translucent base plate (410), the light may transmit through the base plate (410) and reach the film (420) located below the base plate (410) (e.g., in the -z direction).
[0100] In one embodiment, the film (420) may be attached to the back surface (410b) of the base plate (410). For example, to attach the film (420) to the back surface (410b) of the base plate (410), an adhesive layer (430) may be interposed between the base plate (410) and the film (420). The adhesive layer (430) may include, for example, an optically clear adhesive (OCA). The adhesive layer (430) may be attached to each of the base plate (410) and the film (420), thereby attaching the film (420) to the back surface (410b) of the base plate (410).
[0101] In one embodiment, the film (420) may include a substrate layer (421), an ultraviolet molding layer (422), a reflective layer (423), and / or a printing layer (424). The film (420) may enhance the aesthetic quality of the cover plate (211) by causing optical effects such as reflection, interference, refraction, and / or diffraction of light.
[0102] For example, the UV molding layer (422) may be positioned on the back of the base plate (410). The UV molding layer (422) may include a plurality of patterns (440) that cause reflection and / or refraction of light passing through the base plate (410). For example, the plurality of patterns (440) may be formed within the UV molding layer (422). However, the present invention is not limited thereto.
[0103] For example, the ultraviolet molding layer (422) can be formed by curing a molten ultraviolet curable resin. The ultraviolet molding layer (422) including a plurality of patterns (440) can be formed by forming a plurality of patterns (440) in a molten ultraviolet curable resin and then curing them using an ultraviolet lamp. The plurality of patterns (440) can be formed by a combination of patterns including valleys (e.g., valleys (441) in FIGS. 4C and 4D) and peaks (e.g., peaks (442) in FIGS. 4C and 4D). The visual effect caused by the plurality of patterns (440) can be based on the direction in which the plurality of patterns (440) extend and are arranged, the height of the plurality of patterns (440) by the peaks and valleys, the angle of the slope of the plurality of patterns (440), and / or the shape of the plurality of patterns (440).
[0104] For example, the reflective layer (423) may be positioned on the back surface (422a) of the ultraviolet molding layer (422). The reflective layer (423) may be disposed on the back surface (422a) of the ultraviolet molding layer (422). The reflective layer (423) may be configured to reflect light transmitted through the base plate (410). For example, light transmitted through the base plate (410) may be reflected based on the reflectivity of the reflective layer (423). When the reflective layer (423) has a relatively high reflectivity, the amount of light reflected by the film (420) may be relatively increased, and when the reflective layer (423) has a relatively low reflectivity, the amount of light reflected by the film (420) may be relatively decreased. Light passing through the base plate (410) can be provided to the outside of the cover plate (211) after being reflected by the ultraviolet molding layer (422) and the reflection layer (423).
[0105] For example, the substrate layer (421) may be interposed between the base plate (410) and the ultraviolet molding layer (422). The substrate layer (421) may be a layer that serves as the base of the film (420) and may include a polymer. For example, the substrate layer (421) may include, but is not limited to, PET (polyethylene terephthalate). For example, the substrate layer (421) may be omitted. When the film (420) includes the substrate layer (421), the substrate layer (421) may be in contact with the adhesive layer (430). The ultraviolet molding layer (422) may be positioned on the back surface (421a) of the substrate layer (421).
[0106] For example, the print layer (424) may be substantially opaque. The print layer (424) may be positioned on the back surface (423a) of the reflective layer (423). The substantially opaque print layer (424) may not substantially transmit light, but may absorb or reflect incident light. By absorbing or reflecting light by the print layer (424), the print layer (424) may block structures or components disposed under the cover plate (211) from being visible from the outside. The print layer (424) may include ink having a specific color. When the cover plate (211) is viewed from the outside, the color expressed by the ink of the print layer (424) may be visible, so the print layer (424) may substantially embody the color of the cover plate (211).
[0107] As described above, a film (420) can be formed by laminating a substrate layer (421), an ultraviolet molding layer (422), a reflective layer (423), and / or a print layer (424). However, the film (420) including the substrate layer (421), the ultraviolet molding layer (422), the reflective layer (423), and / or the print layer (424) is merely exemplary, and embodiments within the present disclosure are not limited thereto. For example, the film (420) can be formed by modifying or omitting at least one of the substrate layer (421), the ultraviolet molding layer (422), the reflective layer (423), and / or the print layer (424). For example, the film (420) can be formed by integrally forming the reflective layer (423) and the print layer (424). Various examples of the film (420) will be described later with reference to FIGS. 9, 10, 11, 12, and 13.
[0108] Referring to FIG. 4C, the plurality of patterns (440) may be of a lenticular type. The cross-section of the plurality of patterns (440) of the lenticular type may have an approximately semicircular shape. The plurality of patterns (440) may include a valley (441) having a minimum height and a peak (442) having a maximum height. The height between the valley (441) and the peak (442) may correspond to the height of each of the plurality of patterns (440). The height may be about 3 um, but is not limited thereto. The width (W) of each of the plurality of patterns (440) may be about 60 um, but is not limited thereto. The plurality of patterns (440) having a semicircular cross-section may be arranged in parallel to each other to implement a three-dimensional texture to a user looking at the cover plate (211). For example, since the user's left and right eyes are spaced apart from each other, binocular disparity may be caused by light refraction on the surface of each of the plurality of patterns (440). The plurality of lenticular-type patterns (440) can provide a three-dimensional texture by utilizing the user's binocular disparity.
[0109] Referring to FIG. 4D, the plurality of patterns (440) may be of a prism type. The cross-section of the plurality of patterns (440) of the prism type may have an approximately triangular shape. The height between the valley (441) and the peak (442) may correspond to the height of each of the plurality of patterns (440). The height may be about 3 um, but is not limited thereto. The width (W) of each of the plurality of patterns (440) may be about 60 um, but is not limited thereto. Each of the plurality of patterns (440) may include a valley (441) having a minimum height and a peak (442) having a maximum height. The plurality of patterns (440) having a triangular cross-section may be arranged in parallel with each other. The plurality of patterns (440) having a triangular cross-section may provide a visual effect by causing a prism effect by utilizing the refraction and dispersion of light.
[0110] Figure 5a illustrates a film according to one embodiment. Figure 5b is a drawing illustrating a light-blurring phenomenon by the film. Figure 5c illustrates a cover plate illustrating a light-blurring phenomenon.
[0111] Referring to FIG. 5A, the film (420) may have a roughly rectangular shape having a long side (420a) and a short side (420b) to correspond to the shape of the cover plate (211). The edge portions of the film (420) may be at least partially rounded, but the overall shape of the film (420) may be rectangular. The long sides (420a) may be referred to as two sides having relatively long lengths among the four sides of the rectangle, and the short sides (420b) may be referred to as two sides having relatively short lengths among the four sides of the rectangle. For example, the long sides (420a) may include a first side (501) and a second side (502) opposite to the first side (501). For example, the short side (420b) may include a third side (503) and a fourth side (504) opposite to the third side (503).
[0112] According to one embodiment, a plurality of patterns (440) may be arranged in parallel with each other. Each of the plurality of patterns (440) may have a constant width (W). Boundaries (440a, 440b) between the plurality of patterns (440) may define the width (W) of the plurality of patterns (440). Each of the boundaries (440a, 440b) may be spaced apart by the width (W) of each of the plurality of patterns (440). The extension direction of the plurality of patterns (440) may have a slope with respect to the long side (420a).
[0113] According to one embodiment, the plurality of patterns (440) may be inclined with respect to the extension direction (e.g., y-axis direction) of the long side (420a). The inclination of the plurality of patterns (440) with respect to the long side (420a) may be caused by the manufacturing tolerance of the film (420). For example, when the plurality of patterns (440) are formed within an ultraviolet molding layer (e.g., the ultraviolet molding layer (422) of FIG. 4B), as described above, the plurality of patterns (440) may be formed by forming the plurality of patterns (440) in a molten ultraviolet curable resin and then curing the same using an ultraviolet lamp (ultraviolet molding process). After the ultraviolet molding layer (422) including the plurality of patterns (440) is laminated, the film (420) may be subjected to a laser cutting process according to the outer shape, thereby manufacturing a rectangular film (420). At this time, due to the tolerance of the UV molding process and the laser cutting process, the extension direction of the plurality of patterns (440) and the extension direction of the long side (420a) of the film (420) may be misaligned. Even if the plurality of patterns (440) are designed to be parallel to the long side (420a) of the film (420), the plurality of patterns (440) may be tilted with respect to the long side (420a) due to the tolerance. Within the present disclosure, the angle of inclination between the plurality of patterns (440) and the long side (420a) may be referred to as a tilt angle (A).
[0114] As the above tilt angle (A) is formed, a light collection phenomenon may occur. Referring to FIG. 5A, as the plurality of patterns (440) are tilted with respect to the long side (420a), a portion where the plurality of patterns (440) are cut off on the long side (420a) and a portion where the plurality of patterns (440) are cut off on the short side (420b) may be formed. As the plurality of patterns (440) are extended to be tilted with respect to the long side (420a), the plurality of patterns (440) may come into contact with the short side (420b), and therefore, the plurality of patterns (440) may be cut off at a portion where they come into contact with the short side (420b). If the plurality of patterns (440) extend parallel to the long side (420a), the plurality of patterns (440) and the long side (420a) may not be in contact, but as described above, due to the tolerance of the manufacturing process, the plurality of patterns (440) are inclined with respect to the long side (420a), and therefore, some of the plurality of patterns (440) may be cut off at the part in contact with the long side (420a).
[0115] According to one embodiment, among the plurality of patterns (440), one or more patterns that are in contact with the long side (420a) may be in contact with the long side (420a). For example, the plurality of patterns (440) may include a first pattern (510) that is in contact with the long side (420a) (e.g., the first side (501)) and a second pattern (520) adjacent to the first pattern (510). The first pattern (510) and the second pattern (520) may be cut off at a portion in contact with the long side (420a). The length of the portion in which the first pattern (510) is in contact with the long side (420a) may be referred to as a first length (511), and the length of the portion in which the second pattern (520) is in contact with the long side (420a) may be referred to as a second length (521). Since the plurality of patterns (440) are parallel to each other and each have a constant width (W), the second length (521) can be substantially the same as the first length (511).
[0116] According to one embodiment, a plurality of patterns (440) may be in contact with a short side (420b). The plurality of patterns (440) may be cut off at a portion in contact with the short side (420b) (e.g., the third side (503)). Since the plurality of patterns (440) are parallel to each other and each have a constant width (W), the lengths (505) of portions in which the plurality of patterns (440) are in contact with the short side (420b) may be substantially the same.
[0117] Referring to FIG. 5B, since a plurality of patterns (e.g., a plurality of patterns (440) in FIG. 5A) are broken at a portion where they contact a long side (e.g., a long side (420a) in FIG. 5A), a light collection phenomenon may occur. In FIG. 5B, a path of light that is incident on the cover plate (211), passes through the base plate (410), and is reflected at a portion where the plurality of patterns (440) of the film (420) contact the long side (420a) is illustrated. The portion where the plurality of patterns (440) contact the long side (420a) may be referred to as a portion where the plurality of patterns (440) are broken on the long side (420a).
[0118] The first path (P1) in FIG. 5b represents the path of light at points where the plurality of patterns (440) are in contact with the long side (420a), among the portions where the plurality of patterns (440) are in contact with the long side (420a), and the boundaries between the plurality of patterns (440) (e.g., the boundaries (440a, 440b) in FIG. 5a). For example, the points may be referred to as points where the valleys (441) of the plurality of patterns (440) are in contact with the long side (420a). The second path (P2) in FIG. 5b represents the path of light in areas where the plurality of patterns (440) are in contact with the long side (420a), excluding the points.
[0119] According to one embodiment, the second path (P2) may be different from the first path (P1). When the plurality of patterns (440) are cut at a portion where they contact the long side (420a), depending on the shape of the plurality of patterns (440) (e.g., the lenticular type of FIG. 4c or the prism type of FIG. 4d), the outer surfaces of the plurality of patterns (440) and the outer surface of the base plate (410) may not be parallel but may be inclined at the boundaries (440a, 440b) between the plurality of patterns (440). For example, as the plurality of patterns (440) are inclined with respect to the long side (420a), an incline may be formed between the outer surface of the base plate (410) and the outer surfaces of the plurality of patterns (440) at the valleys (441) of the plurality of patterns (440). Due to the above inclination, the amount of light reflected in the direction in which the user looks at the cover plate (211) may be relatively small. As the light passing through the cover plate (211) is reflected at the above points, a first path (P1) may be formed.
[0120] In the remaining portions where the plurality of patterns (440) are in contact with the long side (420a) excluding the above boundaries, the outer surfaces of the plurality of patterns (440) and the outer surface of the base plate (410) may be parallel to each other. For example, as the plurality of patterns (440) are cut parallel to the long side (420a), in the remaining area excluding the valleys (441) of the plurality of patterns (440), the outer surfaces of the base plate (410) and the outer surfaces of the plurality of patterns (440) may be substantially parallel to each other. Since the outer surfaces are parallel to each other, the amount of light reflected in the direction in which the user looks at the cover plate (211) may be relatively large due to total reflection. As the light transmitted through the cover plate (211) is reflected on the above areas, a second path (P2) may be formed.
[0121] According to one embodiment, a periodic light collection phenomenon may be caused by different first paths (P1) and second paths (P2). The slope between the outer surface of the cover plate (211) and the outer surfaces of the plurality of patterns (440) may vary periodically. The period may correspond to the length of the portion where the plurality of patterns (440) contacts the long side (420a). Referring to FIG. 5C, a periodic light collection phenomenon may be observed on the long side (211a) of the cover plate (211). Since the periodic light collection phenomenon may be recognized by a user looking at the cover plate (211), it may deteriorate the appearance quality of the cover plate (211). For example, the light collection phenomenon may appear to the user as a defect in the cover plate (211).
[0122] Referring back to FIG. 5a, a light-converging phenomenon can be observed on the short side (420b) according to the same principle as the light-converging phenomenon described above. Since the plurality of patterns (440) extend with an incline with respect to the long side (420a), the length (505) of the portion where the plurality of patterns (440) contact the short side (420b) may be shorter than the length (e.g., the first length (511) or the second length (521)) of the portion where the plurality of patterns (440) contact the long side (420a). When the width (W) of the plurality of patterns (440) is narrow, such as about 0.08 mm or less, even if a light-converging phenomenon occurs on the short side (420b), it may be difficult to discern with the naked eye. Since the light condensation phenomenon on the short side (420b) is difficult to identify with the naked eye, its effect on the appearance quality of the cover plate (e.g., the cover plate (211) of FIG. 4a) may be minimal.
[0123] According to one embodiment, in order to reduce the deterioration of the appearance quality of the cover plate (211), the tilt angle (A) of the plurality of patterns (440) may be limited within a certain range. According to one embodiment, the inclination of the long side (420a) of the plurality of patterns (440) may be provided so that the light formation period is formed to be less than a certain length (e.g., about 0.4 mm). Since the light formation period is formed to be less than a certain length, it may be difficult for a user to identify the light formation phenomenon, and thus the deterioration of the appearance quality of the cover plate (211) may be reduced. Hereinafter, a cover plate (211) according to one embodiment and an electronic device (e.g., the electronic device (101) of FIG. 2) including the cover plate (211) will be described.
[0124] Figures 6a and 6b illustrate multiple patterns of a film according to one embodiment.
[0125] Referring to FIG. 6A, a film (420) according to one embodiment may include a plurality of patterns (440). As described above, the plurality of patterns (440) may be formed within the film (420) attached on the back surface (410b) of a base plate (e.g., the base plate (410) of FIG. 4B). For example, the plurality of patterns (440) may be formed within an ultraviolet molding layer (e.g., the ultraviolet molding layer (422) of FIG. 4B) within the film (420). However, embodiments of the present disclosure are not limited thereto. For example, the plurality of patterns (440) may also be formed on the base plate (410).
[0126] According to one embodiment, the film (420) may have a rectangular shape including a long side (420a) and a short side (420b). The plurality of patterns (440) may have a slope with respect to the long side (420a), and the slope of the plurality of patterns (440) with respect to the long side (420a) may be referred to as a tilt angle (A). The plurality of patterns (440) may each have a constant width and may be arranged parallel to each other.
[0127] According to one embodiment, a light formation phenomenon may be induced on the long side (420a) by a portion (e.g., 622, 632) where the plurality of patterns (440) contact the long side (420a). As described above, the light formation phenomenon on the long side (420a) may be formed periodically. The period of the light formation may correspond to the length of the portion where the plurality of patterns (440) contact the long side (420a).
[0128] According to one embodiment, the angle of the inclination of the plurality of patterns (440) may be formed so that the light formation period is formed to be less than a certain length. Since the light formation period corresponds to the length of the portion where the plurality of patterns (440) are in contact with the long side (420a), the formation of the light formation period to be less than a certain length may substantially correspond to the formation of the length of the portion where the plurality of patterns (440) are in contact with the long side (420a) to be less than the certain length.
[0129] According to one embodiment, the length of the portion of one or more patterns (601) that contact the long side (420a) that contacts the long side (420a) may be less than or equal to a predetermined length. For example, the predetermined length may be about 0.4 mm, but is not limited thereto.
[0130] According to one embodiment, the angle of inclination (e.g., tilt angle A) of the long side (420a) of the plurality of patterns (440) may be based on the width (e.g., 611, 621) and the length (e.g., about 0.4 mm) of the plurality of patterns (440).
[0131] For example, one or more patterns (601) in contact with the long side (420a) may include a first pattern (610), a second pattern (620), and a third pattern (630) that are adjacent to each other. The second pattern (620) may be positioned between the first pattern (610) and the second pattern (620). Since the plurality of patterns (440) each have a constant width, the width (611) of the first pattern (610), the width (621) of the second pattern (620), and the width of the third pattern (630) may be substantially the same.
[0132] For example, a first triangle (640) may be defined by a portion (622) where the second pattern (620) and the long side (420a) meet, a first width (611) of the second pattern (620), and a first boundary (651) between the first pattern (610) and the second pattern (620). Since the first width (611) of the second pattern (620) may be defined as the shortest distance between the first pattern (610) and the second pattern (620), the first triangle (640) may be a right triangle. The length of the first hypotenuse of the first triangle (640) may correspond to the length of the portion (622) where the second pattern (620) and the long side (420a) meet. The first angle (A1) between the first boundary (651) between the first pattern (610) and the second pattern (620) and the long side (420a) may correspond to the tilt angle (A), which is the inclination of the plurality of patterns (440) with respect to the long side (420a). The base of the first triangle (640) may correspond to the first boundary (651) between the first pattern (610) and the second pattern (620). In the first triangle (640), the length of the first hypotenuse, which is the length of the portion (622) where the second pattern (620) and the long side (420a) meet, corresponds to the light formation period on the long side (420a), and therefore, the length of the first hypotenuse may be less than or equal to a certain length. For example, the length of the first hypotenuse may be less than or equal to about 0.4 mm. According to the law of sines, the first angle (A1) can be determined by the following mathematical expression 1. In the present disclosure, the fact that an angle is determined by a mathematical expression can indicate that the angle is defined to satisfy the mathematical expression.
[0133]
[0134] (Here, A represents the angle of the inclination (e.g., the first angle (A1)), a represents the length of a portion (622) of one or more patterns (601) that are in contact with the long side (420a) among the plurality of patterns (440) and that are in contact with the long side (420a), and b represents the width of the plurality of patterns (440).)
[0135] In the above mathematical expression 1, a is the length of the portion (622) where the second pattern (620) is in contact with the long side (420a), which is equal to or less than the predetermined length (e.g., about 0.4 mm), and b is the width of the second pattern (620), which is a value determined when forming a plurality of patterns (440), so the first angle (A1) can be determined by the following mathematical expression 2.
[0136]
[0137] In the above mathematical expression 2, when a is set to 0.4 mm or less, the first angle (A1) corresponding to the tilt angle (A) may be greater than or equal to arcsin(b / 0.4).
[0138] Since the plurality of patterns (440) are arranged in parallel with each other at regular intervals, the above-described descriptions can be substantially equally applied to the third pattern (630) adjacent to the second pattern (620).
[0139] For example, a second triangle (660) may be defined by a portion (632) where the third pattern (630) touches the long side (420a), a second width (621) of the third pattern (630), and a second boundary (652) between the second pattern (620) and the third pattern (630). Since the second width (621) of the third pattern (630) may be defined as the shortest distance between the second pattern (620) and the third pattern (630), the second triangle (660) may be a right triangle. The length of the second hypotenuse of the second triangle (660) may correspond to the length of the portion (632) where the third pattern (630) touches the long side (420a). The second angle (A2) between the second boundary (652) between the second pattern (620) and the third pattern (630) and the long side (420a) may correspond to the tilt angle (A), which is the inclination of the plurality of patterns (440) with respect to the long side (420a). The base of the second triangle (660) may correspond to the second boundary (652) between the second pattern (620) and the third pattern (630). In the second triangle (660), the length of the second hypotenuse, which is the length of the portion (632) where the third pattern (630) and the long side (420a) meet, corresponds to the light formation period on the long side (420a), and therefore, the length of the second hypotenuse may be less than or equal to a certain length. For example, the length of the second hypotenuse may be less than or equal to about 0.4 mm. According to the law of sines, the second angle (A2) can be determined by the mathematical expression 1 above. In the mathematical expression 1 above, a is the length of the portion (632) where the third pattern (630) is in contact with the long side (420a), which is equal to or less than the predetermined length (e.g., about 0.4 mm), and b is the width of the third pattern (630), which is a value determined when forming a plurality of patterns (440), so the second angle (A2) can be determined by the mathematical expression 2 above.
[0140] When the tilt angle (A) of the plurality of patterns (440) is set to an angle greater than or equal to the angle determined by mathematical expression 2, the length of the plurality of patterns (440) in contact with the long side (420a) may be formed to be less than or equal to a certain length. As the length is formed to be less than or equal to the certain length, the light formation period is formed to be less than or equal to the certain length, and it may be difficult for a user to identify the light formation period.
[0141] According to one embodiment, the plurality of patterns (440) may be in contact with the long side (420a) and the short side (420b) of the film (420). The plurality of patterns (440) being in contact with the long side (420a) and the short side (420b) may indicate that there is no portion (e.g., an offset region) in the film (420) where the plurality of patterns (440) are removed or omitted. As described above, since the tilt angle (A) of the plurality of patterns (440) is formed so that the light gathering phenomenon on the long side (420a) is substantially not recognized by the user, the light gathering phenomenon recognized at the edge portion of the cover plate (e.g., the cover plate (211) of FIG. 4A) can be resolved. In order to reduce light collection at the edge portion of the cover plate (211), the plurality of patterns (440) can be formed to contact the long side (420a) and the short side (420b) without having to omit the plurality of patterns (440) around the edge portion of the film (420). According to one embodiment, the film (420) may not include a portion where the plurality of patterns (440) are removed or omitted in order to reduce the light collection phenomenon.
[0142] Referring to Fig. 6b, a plurality of patterns (440) having an inclination with respect to the long side (420a) may be in contact with the short side (420b). A light formation phenomenon may be induced on the short side (420b) by a portion (e.g., 623) where the plurality of patterns (440) are in contact with the short side (420b). The light formation phenomenon on the short side (420b) may be formed periodically. The light formation period may correspond to the length of the portion where the plurality of patterns (440) are in contact with the short side (420b).
[0143] For example, a third triangle (670) may be defined by a portion (623) where the second pattern (620) touches the short side (420b), a first width (611) of the second pattern (620), and a first boundary (651) between the first pattern (610) and the second pattern (620). Since the first width (611) of the second pattern (620) may be defined as the shortest distance between the first pattern (610) and the second pattern (620), the third triangle (670) may be a right triangle. The third hypotenuse of the third triangle (670) may correspond to the length of a portion (623) where the second pattern (620) touches the short side (420b). The third angle (A3) between the first width (611) of the second pattern (620) and the third hypotenuse may correspond to the tilt angle (A), which is the inclination of the plurality of patterns (440) with respect to the long side (420a). The height of the third triangle (670) may correspond to the first boundary (651) between the first pattern (610) and the second pattern (620). In the third triangle (670), the length of the third hypotenuse, which is the length of the portion (623) where the second pattern (620) and the short side (420b) meet, may correspond to the light formation period on the short side (420b). According to the law of cosines, the third angle (A3) may be calculated by the following mathematical equation 3.
[0144]
[0145] (Here, A represents the angle of the inclination (e.g., the third angle (A3)), b represents the width of the plurality of patterns (440), and c represents the length of the portion (623) where the plurality of patterns (440) contact the short side (420b))
[0146] Referring to the above mathematical expression 3, the light formation on the short side (420b) may be substantially invisible to the user because it is shorter than the light formation on the long side (420a). According to one embodiment, in order to reduce the deterioration of the appearance quality of the cover plate (211) due to the light formation, the tilt angle (A) may be determined so that the light formation period on the long side (420a) is less than a certain length (e.g., approximately 0.4 mm).
[0147] Table 1 below shows the light formation period on the long side (420a) and the light formation period on the short side (420b) calculated according to the width and tilt angle (A) of the pattern.
[0148]
[0149] Referring to Table 1 above, when the pattern width is about 0.06 mm, the tilt angle (A) for making the light formation period on the long side (420a) less than a certain length (e.g., about 0.4 mm) may be about 8.5 degrees or more. When the pattern width is about 0.03 mm, the tilt angle (A) for making the light formation period on the long side (420a) less than a certain length (e.g., about 0.4 mm) may be about 4.5 degrees or more. According to one embodiment, the tilt angles (A) of the plurality of patterns (440) may be set so that the light formation period on the long side (420a) of the film (420) is less than or equal to 0.4 mm. The fact that the light formation period on the long side (420a) is 0.4 mm or less can be referred to as the fact that, among the plurality of patterns (440), one or more patterns (601) that are in contact with the long side (420a) have a length of 0.4 mm or less at the portion in contact with the long side (420a). For example, when the width of the plurality of patterns (440) is about 0.06 mm, the tilt angle (A) of the plurality of patterns (440) can be set to about 8.5 degrees or more. For example, when the width of the plurality of patterns (440) is about 0.03 mm, the tilt angle (A) of the plurality of patterns (440) can be set to about 4.5 degrees or more.
[0150] According to one embodiment, the cover plate (211) may have a plurality of patterns (440) with a tilt angle (A) such that the light condensation phenomenon is substantially undetectable to the user. Even if the light condensation phenomenon occurs, the deterioration of the appearance quality of the cover plate (211) may be reduced as the light condensation cycle is formed to a length that is difficult to discern with the naked eye of the user (e.g., approximately 0.4 mm or less).
[0151] The film (420) illustrated in FIGS. 6a and 6b is illustrated in a form in which a plurality of patterns (440) are cut along the long side (420a), but the embodiment of the present disclosure is not limited thereto.
[0152] Figure 6c illustrates a film according to one embodiment.
[0153] Referring to FIG. 6c, a plurality of patterns (440) may be formed at portions that are interrupted on the short side (420b) of the film (420). The plurality of patterns (440) may be in contact with the short side (420b). Due to the portion where the plurality of patterns (440) are in contact with the short side (420b), a light-condensing phenomenon may occur on the short side (420b). If the length of the portion where the plurality of patterns (440) are in contact with the long side (420a) is short, the light-condensing phenomenon on the long side (420a) may not be substantially recognized by the user.
[0154] Comparing the embodiment of FIG. 6b with the embodiment of FIG. 6c, the embodiment of FIG. 6b and the embodiment of FIG. 6c may be substantially the same, except that the position of the width (611) between the plurality of patterns (440) and the position of the boundary (651) between the plurality of patterns (440) are changed as the tilt angle (A) of the plurality of patterns (440) is changed.
[0155] According to one embodiment, in order to prevent the light formation phenomenon on the short side (420b) from being substantially recognized by the user, the tilt angle (A) may be determined such that the light formation period on the short side (420b) is less than or equal to a predetermined length (e.g., about 0.4 mm). The period may correspond to the length of the portion (623) where the plurality of patterns (440) contact the short side (420b). According to one embodiment, in order to form the light formation period on the short side (420b) of the plurality of patterns (440) to be less than or equal to a predetermined length (e.g., about 0.4 mm), the angle between the plurality of patterns (440) and the short side (420b) (e.g., the third angle (A3) in FIG. 6b) may be calculated by the aforementioned mathematical expression 3.
[0156] In the above mathematical expression 1, a is the length of the portion (622) where the second pattern (620) is in contact with the long side (420a), which is equal to or less than the predetermined length (e.g., about 0.4 mm), and b is the width of the second pattern (620), which is a value determined when forming a plurality of patterns (440), so the first angle (A1) can be determined by the following mathematical expression 4.
[0157]
[0158] (Here, A represents the angle of the inclination (e.g., the third angle (A3)), b represents the width of the plurality of patterns (440), and c represents the length of the portion (623) where the plurality of patterns (440) contact the short side (420b))
[0159] In the above mathematical expression 4, when c is set to 0.4 mm or less, the third angle (A3) corresponding to the tilt angle (A) may be greater than or equal to arccos(b / 0.4).
[0160] The film (420) illustrated in FIGS. 6A, 6B, and 6C is illustrated such that each of the plurality of patterns (440) has a constant width, but the embodiments of the present disclosure are not limited thereto.
[0161] FIG. 6d illustrates a film according to one embodiment comprising a plurality of patterns having different widths.
[0162] Referring to FIG. 6D, the widths of the plurality of patterns (440) may not be constant. For example, the plurality of patterns (440) may include a first pattern (681) having a first width (W1) and a second pattern (682) having a second width (W2). The first width (W1) may be wider than the second width (W2). When the plurality of patterns (440) include the first pattern (681) and the second pattern (682), the tilt angle (A) of the plurality of patterns (440) may be determined based on a pattern having a relatively wider width. For example, when the first width (W1) is about 0.06 mm and the second width (W2) is about 0.03 mm, the tilt angle (A) may be determined based on the first width (W1). In the above mathematical expression 1, the b value corresponding to the width of the plurality of patterns (440) may be the first width (W1) (e.g., about 0.06 mm), and the tilt angle (A) may be calculated according to the first width (W1).
[0163] Although not shown, the plurality of patterns (440) may further include a third pattern having a third width. For example, the first width may be approximately 0.06 mm, the second width may be approximately 0.05 mm, and the third width may be approximately 0.04 mm. In this case, the tilt angle may be calculated based on the first width having the widest width. In addition, the film (420) may include a plurality of patterns (440) having various widths, and the tilt angle may be determined based on the widest width.
[0164] Figure 7 illustrates a cover plate according to one embodiment and cover plates according to a comparative example.
[0165] As described above, due to tolerances in the manufacturing process, the plurality of patterns (e.g., the plurality of patterns (440) in FIG. 6a) may be inclined with respect to the long side (e.g., the long side (420a) in FIG. 6a) of the film (e.g., the film (420) in FIG. 6a), and thus, a light collection phenomenon may occur on the long side (420a). When the plurality of patterns (440) are parallel to the long side (420a), the light collection phenomenon may not occur, but the plurality of patterns (440) parallel to the long side (420a) may be difficult to implement due to tolerances in the manufacturing process. According to one embodiment, the cover plate (211) has a tilt angle (e.g., tilt angle (A) of FIG. 6a) of the plurality of patterns (440) that is set based on the width of the plurality of patterns (440) and the length of one or more patterns that contact the long side (420a) among the plurality of patterns (440) to contact the long side (420a), thereby reducing deterioration of the appearance quality due to the light gathering phenomenon.
[0166] The examples illustrated in FIG. 7 show the appearance of the cover plate according to the tilt angle (A) when the width of each of the plurality of patterns (440) is about 0.06 mm. The cover plate (701) according to the first comparative example of FIG. 7 has a tilt angle (A) of about 2 degrees. The cover plate (702) according to the second comparative example of FIG. 7 has a tilt angle (A) of about 5 degrees. The cover plate (211) according to one embodiment of FIG. 7 has a tilt angle (A) of about 10 degrees.
[0167] Referring to Table 1 above, in the case of the cover plate (701) according to the first comparative example in which the tilt angle (A) is about 2 degrees, the light formation period on the long side (701a) of the cover plate (701) may be about 1.72 mm. Referring to Table 1 above, in the case of the cover plate (702) according to the second comparative example in which the tilt angle (A) is about 5 degrees, the light formation period on the long side (702a) of the cover plate (702) may be about 0.69 mm. In the case of the cover plate (701) according to the first comparative example and the cover plate (702) according to the second comparative example, since the light formation period is relatively long, the user can identify the light formation formed on the edge portions of the cover plates (701, 702). Since the light condensation can be discerned by the user's eyes, the appearance quality of the cover plates (701, 702) according to the comparative examples may deteriorate.
[0168] When the tilt angle (A) is about 10 degrees, since the light formation cycle is formed relatively short, it may be difficult for a user to identify the light formation with the naked eye. Referring to Table 1 above, when the tilt angle (A) is about 10 degrees, the light formation cycle on the long side (211a) of the cover plate (211) may be about 0.35 mm. Even if the light formation phenomenon occurs with a cycle of about 0.35 mm, it may be difficult for a user to identify the light formation phenomenon due to the resolution of the human eye. In the case of the cover plate (211) according to one embodiment, since the light formation is difficult to identify, the deterioration of the appearance quality due to the light formation may be reduced. The cover plate (211) according to one embodiment may have excellent appearance quality.
[0169] In the above description, the lower limit value of the tilt angle (A) has been described. As described above, the tilt angle (A) may be equal to or greater than the lower limit value based on the width of the plurality of patterns (440) and the predetermined length such that the light formation period on the long side (420a) is equal to or less than a predetermined length (e.g., approximately 0.4 mm). If the upper limit value of the tilt angle (A) is not set, the tilt angle (A) may be equal to or greater than 45 degrees. When the tilt angle (A) is equal to or greater than 45 degrees, the periods of contact between the long side (420a) and the short side (420b) are switched, and thus a light formation phenomenon on the short side (420b) may occur. Hereinafter, the upper limit value of the tilt angle (A) will be described.
[0170] Figure 8 is a graph showing the amount of light reflected according to the tilt angle of multiple patterns.
[0171] As the tilt angle (e.g., the tilt angle (A) of FIG. 6A) increases, the reflection characteristics of the cover plate (e.g., the cover plate (211) of FIG. 4A) may change. The graph (800) of FIG. 8 is a graph showing the amount of light reflected to the user's eyes with respect to the direction in which the cover plate (211) is viewed. The x-axis of the graph (800) corresponds to the angle of the direction in which the user views the cover plate (211) with respect to the vertical direction of the cover plate (211). For example, 30 degrees represents a state in which the cover plate (211) is viewed at an angle of about 30 degrees with respect to the direction perpendicular to the cover plate (211). The y-axis of the graph (800) corresponds to a value showing the relative amount of light reflected to the user's eyes. The stronger the amount of reflected light, the brighter the cover plate (211) may appear to the user's eyes, and the weaker the amount of reflected light, the darker the cover plate (211) may appear to the user's eyes.
[0172] The first graph (801) of FIG. 8 represents the amount of light reflected to the user's eyes with respect to the angle (hereinafter, viewing angle) at which the cover plate (211) is viewed when the tilt angle (A) (hereinafter, tilt angle (A)) of the long side (e.g., the long side (420a) of FIG. 6A) of the plurality of patterns (e.g., the plurality of patterns (440) of FIG. 6A) is approximately 0 degrees. The second graph (802) represents the amount of light reflected to the user's eyes with respect to the viewing angle when the tilt angle (A) of the plurality of patterns (440) is approximately 1 degree. The third graph (803) represents the amount of light reflected to the user's eyes with respect to the viewing angle when the tilt angle (A) of the plurality of patterns (440) is approximately 5 degrees. The fourth graph (804) represents the amount of light reflected to the user's eyes with respect to the viewing angle when the tilt angle (A) of the plurality of patterns (440) is about 10 degrees. The fifth graph (805) represents the amount of light reflected to the user's eyes with respect to the viewing angle when the tilt angle (A) of the plurality of patterns (440) is about 12 degrees. The sixth graph (806) represents the amount of light reflected to the user's eyes with respect to the viewing angle when the tilt angle (A) of the plurality of patterns (440) is about 15 degrees. The seventh graph (807) represents the amount of light reflected to the user's eyes with respect to the viewing angle when the tilt angle (A) of the plurality of patterns (440) is about 20 degrees.
[0173] Referring to the graph of Fig. 8, the amount of light reflected to the user's eyes may decrease depending on the viewing angle. For example, when viewing the cover plate (211) at an angle of about 20 degrees or less and about 40 degrees or more, the amount of light reflected to the user's eyes (reflection amount) may decrease. If the reflection amount decreases, the cover plate (211) appears dark, making it difficult to discern the visual effect of the multiple patterns (440). Table 2 below is a table that numerically represents the graph of Fig. 8.
[0174]
[0175] Referring to the graph of FIG. 8 and Table 2 above, it can be confirmed that the tilt angle (A) at which the amount of light reflected into the user's eyes drastically decreases as the viewing angle changes. Comparing the sixth graph (806) and the seventh graph (807) of FIG. 8, when the tilt angle (A) increases from 15 degrees to 20 degrees, the amount of light reflection drastically decreases at a viewing angle of about 20 degrees or less and about 40 degrees or more. Referring to Table 2, when the user views the cover plate (211) at a viewing angle of about 15 degrees, the amount of light reflection drastically decreases at a tilt angle (A) of about 20 degrees. Referring to Table 2, when the user views the cover plate (211) at a viewing angle of about 45 degrees, the amount of light reflection drastically decreases at a tilt angle (A) of about 20 degrees. When the amount of light reflection decreases rapidly, the brightness of the cover plate (211) recognized by the user decreases rapidly, so the appearance quality of the cover plate (211) may deteriorate.
[0176] According to one embodiment, the inclination of the long side (420a) of the plurality of patterns (440) may be about 15 degrees or less. As the upper limit of the tilt angle (A) of the plurality of patterns (440) is limited to about 15 degrees or less, the brightness of the cover plate (211) recognized by the user can be maintained above a certain brightness, thereby reducing deterioration of the appearance quality.
[0177] Figures 9, 10, 11, 12, and 13 illustrate cover plates according to various embodiments.
