[0091] According to one embodiment, the second color layer (480) may include a first refractive layer (481). The second color layer (480) may include a second refractive layer (482). The refractive index of the first refractive layer (481) may be greater than the refractive index of the second refractive layer (482). The refractive index (n1) of the first refractive layer (481) may be in a range from 2.00 to 2.1. For example, the refractive index (n1) of the first refractive layer (481) may be 2.05. The refractive index (n2) of the second refractive layer (482) may be in a range from 1.45 to 1.5. For example, the refractive index (n2) of the second refractive layer (482) may be 1.46. The first refractive layer (481) may include silicon nitride (Si3N4). The second refractive layer (482) may include silicon oxide (SiO2).

[0092] According to one embodiment, the second color layer (480) may be formed by alternately stacking a plurality of first refractive layers (481) and a plurality of second refractive layers (482).

For example, each of the plurality of first refractive layers (481) may be disposed between each of the plurality of second refractive layers (482). The first refractive layer (481) may include a 1-1 refractive layer (481-1) and a 1-2 refractive layer (481-2).

However, in the second color layer according to one embodiment of the present disclosure, only the first refractive layer (481) may be placed.

[0093] The table below may be an example showing the number of first refractive layers (481) and second refractive layers (482) constituting the second color layer (480) and the thickness of each layer according to the stacking order.

[0094] Type Thickness (nm) Direction 1 Refractive layer 372.62↑ Direction toward the outside of the housing↓ Direction toward the inside of the housing 2 Refractive layer 68.96 First refractive layer 56.2 Second refractive layer 77.99 First refractive layer 46.61 Second refractive layer 106.53 First refractive layer 38.51 Second refractive layer 78.64 First refractive layer 172.67 Second refractive layer 31.91 First refractive layer 336.24 Second refractive layer 20

[0095] According to one embodiment, the angle of light transmitted through the second color layer (480) and incident on the glass layer (410) may vary depending on the angle at which light is incident on the second color layer (480). Light from outside the cover (400) may be incident on the second color layer (480) at a first angle (α1). The first refractive layer (481) may form the outermost layer of the cover (400). The first refractive layer (481) may have a first thickness (t1), and the second refractive layer (482) may have a second thickness (t2). The thickness (t1) of the first refractive layer (481) of the outermost layer may be smaller than the thickness (t2) of the second refractive layer (482). The light may be incident on the first refractive layer (481). Light incident at a first angle (α1) can be refracted in the first refractive layer (481) and propagate at a first refractive angle (β1). Light incident on the first refractive layer (481) can sequentially transmit through the alternately laminated second refractive layer (482) and the first refractive layer (481). Light incident on the first refractive layer (481) can propagate with different incident angles (α2, α3) and refractive angles (β2, β3) at the interface between the respective layers (481, 482). Light that has passed through the second color layer (480) can be incident toward the glass layer (410). Light that has passed through the second color layer (480) can have an incident angle (α) at ​​the interface between the glass layer (410) and the second color layer (480). The above incident angle (α) may vary depending on the first angle (α1) at which light is incident on the second color layer (480). The layer forming the boundary between the second color layer (480) and the glass layer (410) may be a first refractive layer (481). The refractive index of the first refractive layer (481) may be greater than the refractive index of the glass layer (410). Some of the light that has passed through the second color layer (480) may be reflected at the boundary between the first refractive layer (481) and the glass layer (410) and proceed along the first path (P1).According to one embodiment, light (e.g., visible light) incident on the second color layer (480) may be dispersed into different wavelength ranges as it passes through the first refractive layer (481) and the second refractive layer (482). The light may have different colors depending on the wavelength range, and light of different wavelength ranges may have different refractive indices. At the boundary between two media (e.g., the first refractive layer (481) and the glass layer (410)), light of some wavelength ranges may be reflected, and light of the remaining wavelength ranges may be refracted. Some wavelength range of light reflected on the boundary between two media (e.g., the first refractive layer (481) and the glass layer (410)) may travel (e.g., P1 path) with different incident angles (e.g., α4, α5, α6) and refraction angles (e.g., β4, β5) at the boundary between the first and second refractive layers (481, 482). Some wavelength range of light reflected on the boundary between two media (e.g., the first refractive layer (481) and the glass layer (410)) may travel (e.g., P1 path) with a refraction angle (β6) to the outside of the cover (400) through the first refractive layer (481) forming the outermost layer. Reflection at the boundary between two media may also occur at the boundary between the first refractive layer (481) and the second refractive layer (482). Light in the remaining wavelength range refracted at the boundary between two media (e.g., the first refractive layer (481) and the glass layer (410)) can travel in a direction toward the inside of the housing (e.g., the housing (310) of FIG. 5) (e.g., the P2 path). A user can detect light reflected at the boundary between two media (e.g., the first refractive layer (481) and the glass layer (410)) and traveled in a direction toward the outside of the housing (e.g., the housing (301) of FIG. 5).As described above, due to the structure in which the first refractive layer (481) and the second refractive layer (482) are alternately laminated according to the embodiment of the present disclosure, light can be dispersed within the second color layer (480) to form different propagation paths (e.g., P1, P2) for each wavelength region. Depending on the thickness (t1, t2) of the first and second refractive layers (481, 482) and the number of laminated layers (481, 482), the color of light reflected from the second color layer (480) and propagating outside the housing (e.g., the housing (301) of FIG. 5) can be controlled.

[0096] According to one embodiment, the propagation path of light in each spectroscopic wavelength region may vary depending on the angle (α1) at which light is incident on the second color layer (480). Due to the phenomenon of the propagation path of light varying as described above, the color of light identified to the user may vary depending on the angle at which the user observes the cover (400).

[0097] Fig. 9 is a conceptual diagram illustrating the manufacturing process of the second color layer (480). The components described with reference to Fig. 9 may be partially or entirely identical to the components described with reference to Figs. 1 to 8. The components described with reference to Fig. 9 may be partially or entirely identical to the components described with reference to Figs. 10a to 14.

[0098] According to one embodiment, the second color layer (480) may be manufactured by an inductive coupled plasma (ICP) Sputtering method. The ICP Sputtering method may be a method of sputtering a silicon target with argon (Ar) plasma to deposit it on glass, and transferring the glass on which the silicon target is deposited to an ICP plasma zone and exposing it to high-energy nitrogen plasma to nitrify it. For example, referring to FIG. 9, a process of sputtering a silicon target with argon (Ar) plasma to deposit it on glass may be performed at a first location (P1). The silicon deposit produced at the first location (P1) may be transferred to a second location (P2) by the rotation (R) of the drum (P3). The silicon deposit transferred to the second location (P2) may be exposed to high-energy plasma to be nitrified or oxidized. The first refractive layer (481) can be manufactured by exposing the silicon deposited material transferred to the second location (P2) to high-energy nitrogen plasma and nitrifying it. The second refractive layer (482) can be manufactured by exposing the silicon deposited material transferred to the second location (P2) to high-energy oxygen plasma and oxidizing it. The second color layer (480) can be manufactured by alternately repeating nitrification and oxidation on the silicon deposited material while rotating (R) the drum (P3).

[0099] Fig. 10a is a drawing explaining the complementary color relationship between various colors. Fig. 10b is a drawing explaining the apparent color of the second color layer (480) according to the user's viewing angle. Fig. 10c is a drawing explaining the path of light and the light identified to the user. The components described with reference to Figs. 10a, 10b, and 10c may be partly or entirely the same as the components described with reference to Figs. 1 to 9. The components described with reference to Figs. 10a, 10b, and 10c may be partly or entirely the same as the components described with reference to Figs. 11 to 14.

[0100] According to one embodiment, the first color layer (e.g., at least one of the color tint layer (430), the polymer layer (450), and the color printing layer (460) of FIG. 4) may have a first color (C1). The first color (C1) may be red. The second color layer (480) may have a second color (C2) that is a complementary color (S1) to the first color (C1). The second color (C2) may be cyan.

[0101] According to one embodiment, the type of color identified to the user may vary depending on the user's viewing angle (θ). The user's viewing angle (θ) may be defined as the angular displacement of the user's eye position relative to the axis (Z) that passes vertically through the area of ​​the cover (400) that is the object of observation. The user may perceive light of a wavelength range that has traveled along different paths (e.g., path P3 in FIG. 10c) depending on the viewing angle (θ).

[0102] According to one embodiment, the cover (400) may be observed as a color similar to the second color (C2) as the viewing angle (θ) decreases. For example, when the viewing angle (θ) is 0 degrees, the cover (400) may be observed as the second color (C2). As the viewing angle (θ) decreases, the ratio of light reflected from the second color layer (480) to light reflected from the first color layer (e.g., at least one of the color tint layer (430), the polymer layer (450), and the color print layer (460) of FIG. 6) may increase. As the viewing angle (θ) increases, the ratio of light reflected from the second color layer (480) to light reflected from the first color layer (e.g., at least one of the color tint layer (430), the polymer layer (450), and the color print layer (460) of FIG. 6) may decrease. As the viewing angle (θ) decreases, the second color layer (480) can be observed more emphasized than the first color layer, and as the viewing angle (θ) increases, the first color layer can be observed more emphasized than the second color layer (480).

[0103] According to one embodiment, the cover (400) may be observed as a color that is a mixture of a first color (C1) and a second color (C2). The cover (400) may be observed as a color in which the mixing ratio of the first color (C1) to the second color (C2) increases as the viewing angle (θ) increases. For example, when the viewing angle (θ) is 60 degrees, the cover (400) may be observed as a third color (C3). The third color (C3) may be a color that is a mixture of the first color (C1) and the second color (C2). The third color (C3) may have a relationship (S2) rather than a complementary relationship (S1) with the first color (C1). The third color (C3) may be blue. The cover (400) can have a color (e.g., C2, C3, C4, C5, C6, C7, C8, C9, C10) that can be varied depending on the viewing angle (θ). Fig. 10b may be an example showing the relationship between color changes depending on the viewing angle (θ).

[0104] Fig. 11 is a part of a cross-sectional view taken along the line A-A' of Fig. 5 of a cover (500) according to one embodiment of the present disclosure. Fig. 12 is a drawing exemplarily illustrating the shape of the pattern (511) of Fig. 11. The components described with reference to Figs. 11 and 12 may be partially or entirely identical to the components described with reference to Figs. 1 to 10c.

[0105] According to one embodiment, a housing (e.g., housing (301) of FIG. 5) may include a cover (500). The description of the cover (500) of FIG. 11 may be applied in the same manner as the description of the cover (400) described with reference to FIGS. 6 to 10C. For example, the cover (500) may include a shielding layer (520), a color tint layer (530), an adhesive layer (540), a polymer layer (550), a color printing layer (560), a molding layer (561), and a deposition layer (570).

[0106] According to one embodiment, the cover (500) may include a glass layer (510) and a second color layer (580). The second color layer (580) may be deposited on one side of the glass layer (510). The glass layer (510) may include a pattern (511). The pattern (511) may form a haze-treated surface of the glass layer (510). The pattern (511) may include at least one pattern among the first pattern (511a), the second pattern (511b), the third pattern (511c), and the fourth pattern (511d) illustrated in FIG. 12. The pattern (511) may be formed to protrude from the surface of the glass layer (510). The pattern (511) may cause diffuse reflection at the interface between the second color layer (580) and the glass layer (510). As the degree of haze processing of the pattern (511) increases, the color of the second color layer (580) can be observed to be more emphasized than that of the first color layer (for example, at least one of the color tint layer (530), the polymer layer (550), and the color printing layer (560)).

[0107] FIG. 13 is a part of a cross-sectional view taken along line A-A' of FIG. 5 of a cover (600) according to one embodiment of the present disclosure.

For example, the cover (600) may include a shielding layer (620), a color tint layer (630), an adhesive layer (640), a polymer layer (650), a color printing layer (660), a molding layer (661), and a deposition layer (670). The description of the components described above (e.g., shielding layer (620), color tint layer (630), adhesive layer (640), polymer layer (650), color printing layer (660), molding layer (661), deposition layer (670)) can be equally applied to the description of the components described with reference to FIGS. 6 to 10c (e.g., shielding layer (420), color tint layer (430), adhesive layer (440), polymer layer (450), color printing layer (460), molding layer (461), deposition layer (470)).

[0109] According to one embodiment, the cover (600) may include a glass layer (610) and a second color layer (680). The second color layer (680) may be deposited on one side of the glass layer (610). The glass layer (610) may include a pattern (611). The pattern (611) may form a haze-treated surface of the glass layer (610). The pattern (611) may be formed to protrude from the surface of the glass layer (610). The pattern (611) may cause diffuse reflection at the interface between the second color layer (680) and the glass layer (610). As the degree of haze processing of the pattern (611) increases, the color of the second color layer (680) can be observed to be emphasized more than the first color layer (for example, at least one of the color tint layer (630), the polymer layer (650), and the color printing layer (660)). The glass layer (610) may include a pattern (611) patterned on the surface of the glass layer (610) in the shape of stripes or argyle. The pattern (611) of the glass layer (610) may be manufactured through CNC machining. The pattern (611) of the glass layer (610) may be manufactured by a thermoforming method. The thermoforming method may be a manufacturing method of placing glass on a mounting portion of a mold having a stripe or argyle shape and then applying pressure at a temperature of 700 to 800 degrees Celsius and a pressure of 2.5 Mpa.
