[0079] Figure 2 and Figure 3 The electronic device 101 disclosed in the embodiment has a bar or plate-shaped appearance, but the present disclosure is not limited thereto. For example, the electronic device shown may be a part of a rollable electronic device or a foldable electronic device. A "rollable electronic device" may refer to an electronic device at least part of which is arranged with a display (e.g., Figure 4 The display 330) can be bent and deformed and can be rolled or rolled or accommodated in a housing (e.g., Figure 2 The rollable electronic device may be configured to include a housing 310 of the rollable electronic device. The rollable electronic device may include a housing 310 of the rollable electronic device. When the display is stretched or exposed to the outside in a larger area according to the needs of the user, the rollable electronic device may use the expanded second display area. A "foldable electronic device" may refer to an electronic device that can be folded in directions facing two different areas of the display or in directions opposite to each other. Generally speaking, in a portable state, a foldable electronic device may be folded so that two different areas of the display face each other, and in an actual use state, the user may unfold the display so that the two different areas form a substantially flat shape. In some embodiments, according to various embodiments of the present disclosure, the electronic device 101 may be interpreted as including various electronic devices, such as a laptop computer or a home appliance, and portable electronic devices, such as a smart phone.

[0080] Metal can be used as an external material of an electronic device. For example, a metal texture can be realized on an external material of an electronic device by depositing a metal (such as indium) on a housing (e.g., a back cover) of the electronic device. In a state where the housing (e.g., a back cover) is formed of glass, an optically clear adhesive (OCA) is provided on one surface of a polyethylene terephthalate (PET) film, and a metal texture decorative layer is formed on another surface thereof using, for example, an ultraviolet (UV) molded pattern, indium deposition, and / or shield printing. The decorative layer is laminated on the inner surface of the glass, thereby realizing a metal texture glass.

[0081] Figure 4 is a diagram illustrating a housing of an electronic device according to an embodiment of the present disclosure. Figure 5is a graph showing a range in which a first visible layer and a second visible layer are visible according to illuminance according to an embodiment of the present disclosure.

[0082] Embodiments of the present disclosure may include a housing 400 of an electronic device that achieves a hiding effect of a pattern and / or color according to the intensity of illumination. The housing 400 of the electronic device 101 is described herein. However, embodiments of the present disclosure may relate to an accessory cover of the electronic device 101 or a decorative film that can be attached (or mounted) to the electronic device, rather than the housing 400 of the electronic device 101. The housing 400 of the electronic device 101, the accessory cover or the decorative film of the electronic device 101 may include substantially the same components. Therefore, the description of the housing 400 of the electronic device 101 described below may be applied to the accessory cover or the decorative film of the electronic device 101.

[0083] Electronic devices (e.g. Figure 1 The electronic device 101 may include a housing 400 including a base layer 410, a first visible layer 420, and a second visible layer 430. The first visible layer 420 may be formed on a first surface 410a of the base layer 410. The second visible layer 430 may be formed on a second surface 410b of the base layer 410. According to an embodiment, the first visible layer 420, the base layer 410, and the second visible layer 430 may be components stacked sequentially from the outside to the inside of the housing 400. According to an embodiment, relative to the base layer 410, the first visible layer 420 may be referred to as a layer disposed on the front surface of the base layer 410, and the second visible layer 430 may be referred to as a layer disposed on the rear surface of the base layer 410.

[0084] In an embodiment of the present disclosure, a "hiding effect" may be an effect according to whether the second visible layer 430 disposed further inside the housing 400 than the first visible layer 420 is visible or invisible from the outside. For example, when the first visible layer 420 includes a first pattern and the second visible layer 430 includes a second pattern, the second visible layer 430 being visible may refer to that the first pattern of the first visible layer 420 and the second pattern of the second visible layer 430 are regarded as mixed or overlapped, rather than the first pattern of the first visible layer 420 being not observed and the second pattern of the second visible layer 430 being observed. In this case, the second visible layer 430 may be configured to be visible or invisible depending on the illumination environment of the electronic device 101. For example, the second visible layer 430 may be configured to be invisible to the outside of the electronic device 101 in a first illumination environment, and to be visible together with the first visible layer 420 in a second illumination environment.

[0085] The first illumination environment may refer to the external / surrounding environment of the electronic device 101. The housing 400 of the electronic device 101 may be designed with the first illumination environment in mind. For example, the first illumination environment may refer to an indoor illumination environment, such as a residential space or an office. For example, if the first illumination environment is expressed digitally, it may be an illumination environment of 600 Lux or less. The second illumination environment may also refer to an external / surrounding environment. The housing 400 of the electronic device 101 may be designed with the second illumination environment in mind. For example, the second illumination environment may be an outdoor illumination environment, such as a playground or a park. In addition, the second illumination environment may be, for example, an environment in which the electronic device is used outdoors and in strong sunlight. For example, if the second illumination environment is expressed digitally, it may be an illumination environment exceeding 600 Lux.

[0086] refer to Figure 4 and Figure 5 An example is described. In an illumination environment near an indoor illumination of 500 Lux, the second visible layer 430 of the housing 400 of the electronic device is not visible to the outside and shows a hiding effect, so that only the first visible layer 420 is visible to the outside. In addition, both the first visible layer 420 and the second visible layer 430 can be observed in an environment of, for example, 1000 Lux or higher (e.g., 3000 Lux). In this case, it can be observed from the outside that the second visible layer 430 of the housing 400 of the electronic device is mixed or overlapped with the first visible layer 420.

[0087] In order to achieve a hiding effect, it may be necessary to apply a pattern layer and a color layer to each of the front and rear surfaces of the base layer 410 of the housing 400 .

[0088] The base layer 410 may be formed of, for example, polyethylene terephthalate (PET), but is not necessarily limited thereto. The base layer 410 may include a transparent material capable of transmitting light, such as polycarbonate, polysulfone, polyacrylate, polystyrene, polyvinyl chloride, polyvinyl alcohol, polynorbornene, and / or a polyester-based material. Other materials may also be included, such as polyethylene naphthalate. At least a portion of the base layer 410 may include a conductive material. For example, the base layer 410 may be formed of a metal (e.g., aluminum) frame.

[0089] The first visible layer 420 may include a first pattern layer 421 having a first pattern and a first color layer 422 having a first color. Here, the first pattern layer 421 is a pattern layer formed on the first surface 410a of the base layer 410, and may be a pattern molded on one surface of the base layer 410 according to a UV curing method, i.e., a UV molded pattern. The first color layer 422 is a layer formed on one surface of the first pattern layer 421, and may be a color evaporated layer colored, for example, by an evaporation technique. The first color layer 422 may include a first color. The first color may include a combination of one or more colors. In other words, the first color layer 422 may include multiple colors. In this case, the first color layer 422 may be formed by a multi-evaporation technique. For reference, Figure 4 4 and subsequent figures show the type of each layer as a component of the housing 400 and the technology used to form each layer. This is for ease of description, and it should be noted that the scope of the present disclosure is not limited thereto. For example, the scope of the present disclosure is not limited to Figure 4 The type of each layer shown or the technique used to form each layer.

[0090] Figure 6a and Figure 6b is a diagram of a first pattern layer 421 according to an embodiment of the present disclosure. Figure 6a and Figure 6b A state when the first pattern layer 421 is observed by both eyes (left and right eyes) of the user may be shown.

[0091] The first pattern of the first pattern layer 421 may be a lens pattern. According to an embodiment, a cross-section of the first pattern of the first pattern layer 421 may correspond to a lens pattern having a semi-cylindrical shape. According to an embodiment, the lens pattern may be formed to have a height H of approximately 7 μm to 12 μm. According to another embodiment, the lens pattern may be formed to have a pitch P of approximately 60 μm to 90 μm. The lens pattern, as a pattern of the first pattern layer 421 positioned on the first surface 410a of the base layer 410 to exhibit light reflection and refraction, may be superior to a prism or pattern structure having an asymmetric cross-section. For example, when a prism is formed as the pattern of the first pattern layer 421, the hiding effect may be reduced due to the corners of the edges. On the contrary, as Figure 6a As shown, when light passes through the lens pattern due to the visual difference between the left eye and the right eye, the lens pattern can provide a three-dimensional effect. Figure 6b As shown, when the cross section is formed in a semi-cylindrical shape, refraction and reflection of light passing through the lens pattern may have a constant directivity, thereby enabling uniform visibility of the first visible layer 420 .

[0092] Figure 7 is a diagram illustrating a general effect of a lens pattern according to an embodiment of the present disclosure. Figure 7: are views showing how another pattern provided on the rear surface of the lens pattern is observed when there is no restriction due to the lens pattern and when there is restriction due to the lens pattern.

[0093] For example, when there is no restriction due to the lens pattern (no pattern in 702), another pattern 712 set on the rear surface of the lens pattern can be clearly identified. As another example, if there is a restriction caused by the lens pattern (e.g., patterns 704, 706, and 708), light may be refracted or scattered when passing through the lens pattern, resulting in other patterns set on the rear surface (e.g., patterns 714, 716, and 718, respectively) not being clearly observed. For example, when the lens pattern is set at 0 degrees (704), 90 degrees (706), and 45 degrees (708), the visibility of another pattern (714, 716, and 718, respectively) observed on the rear surface of the lens pattern may be reduced. For better understanding, the other patterns (712, 714, 716, and 718) set on the rear surface of the lens pattern are Figure 7 When the fine pattern is formed as other patterns disposed on the rear surface of the lens pattern, visibility can be further reduced.

[0094] Figure 8a and Figure 8b 4 is a diagram illustrating a state in which a first color layer 422 is evaporated on a first pattern layer 421 including a lens pattern according to an embodiment of the present disclosure.

[0095] The lens pattern may have light refraction and reflection effects and a visual effect of representing each image in three dimensions (3D). In an embodiment of the present disclosure, a first pattern layer 421 having a lens pattern is included, thereby realizing a hiding effect using light refraction and reflection effects.

[0096] Furthermore, evaporating and forming the first color layer 422 on the first pattern layer 421 can increase the reflective effect, thereby more easily and effectively achieving the hiding effect.

[0097] For example, it may be difficult to achieve a hiding effect using the shape of the lens pattern formed on the first pattern layer 421 at an indoor illumination level of 600 Lux or less. Therefore, according to an embodiment of the present disclosure, the light reflection effect may be increased by additionally forming a first color layer 422 having a predetermined reflectivity on the surface of the first pattern layer 421. According to an embodiment, the first color layer 422 may be formed of a layer having a reflectivity of approximately 40% to 50%. According to an embodiment, the first color layer 422 may include TiO 2 and SiO 2 About 40% to 50% of the reflectivity can be achieved by TiO 2 and SiO2 For example, the first color layer 422 may include at least one TiO 2 layer and at least one SiO 2 According to an embodiment, TiO is deposited on the first color layer 422. 2 Afterwards, SiO can be deposited using multi-evaporation techniques. 2 . Due to the alternating arrangement of multiple TiO 2 Layers and multiple SiO 2 The first color layer 422 may be formed of a layer having a reflectivity of about 40% to 50% using the difference in refractive index between different material layers. For example, the first color layer 422 may have a stacked structure in which TiO is formed in the first layer. 2 , forming SiO in the second layer 2 , forming TiO in the third layer 2 , and SiO is formed in the fourth layer 2 In this case, if the reflectivity of the first color layer 422 is 40% or less, the pattern and color of the second visible layer 430 may appear tiny from the outside, and if the reflectivity is 50% or more, strong light energy is required to make the pattern and color of the second visible layer 430 visible, so it may be difficult to show the hiding effect under average indoor illumination levels.

[0098] The embodiments of the present disclosure may achieve a hiding effect of the second visible layer 430 formed on the rear surface of the base layer 410 through the reflectivity of the first color layer 422 and the shape (eg, lens pattern) of the first pattern layer 421 .

[0099] Return to reference Figure 4 , the second visible layer 430 may include a second pattern layer 431 having a second pattern and a second color layer 432 having a second color. The second pattern layer 431 is a pattern layer formed on the second surface 410b of the base layer 410, and may be a pattern molded on one surface of the base layer 410 according to a UV curing method, i.e., a UV molded pattern. The second color layer 432 is a layer formed on one surface of the second pattern layer 431, and may be a color evaporation layer colored, for example, by an evaporation technique. The second color layer 432 may include a second color. The second color may include a combination of one or more colors. The second color layer 432 may include multiple colors like the first color layer 422. In this case, the second color layer 432 may be formed by a multi-evaporation technique.

[0100] According to an embodiment, the second color layer 432 may be formed to have a reflectivity of about 30% to 45%. For example, when formed to have a reflectivity of about 5% to 10% lower than that of the first color layer 422, the second color layer 432 may enhance the visibility of the second pattern layer 431 of the second visible layer 430. According to an embodiment, the second pattern layer 431 may be a macro pattern having a random shape. Compared with the first pattern layer 421 formed with a lens pattern, the second pattern layer 431 having a macro pattern is formed so that the overall visibility becomes blurred in a random direction rather than a specific direction. According to an embodiment, the second color layer 432 may include TiO 2 and SiO 2 About 30% to 45% of the reflectivity can be achieved by TiO 2 and SiO 2 For example, the second color layer 432 may include at least one TiO 2 layer and at least one SiO 2 According to an embodiment, TiO is deposited on the second color layer 432. 2 Afterwards, SiO can be deposited using multi-evaporation techniques. 2 . Due to the alternating arrangement of multiple TiO 2 Layers and multiple SiO 2 layers, thus using the refractive index difference between different material layers, the second color layer 432 can be formed of a layer having a reflectivity of approximately 30% to 45%.

[0101] Fig. 9 is a graph of the reflectivity of each wavelength band of the measuring shell according to an embodiment of the present disclosure.

[0102] Fig. 9 The results of an experiment performed on three samples of different wavelength bands having a color evaporated layer (first color layer) on the front surface and a color evaporated layer (second color layer) on the rear surface in the same illumination environment while changing the structural conditions of the lens pattern on the front surface and the reflection conditions of the color evaporated layer (first color layer) are shown.

[0103] Reference Fig. 9, Example 1 (solid line) may show a housing including a first color layer 422 having a reflectivity of about 40% to 50% in a visible light band of about 420nm to 480nm. Example 1 (solid line) may show a sample that achieves a hiding effect, i.e., the color of the first color layer 422 having a reflectivity of about 40% to 50% is observed, but the rear surface is not observed in the band (420nm to 480nm) in which the color of the color vapor-deposited layer on the front surface is observed. Example 1 may show a state when the height of the lens pattern is about 7μm to 12μm, the pitch is about 60μm to 90μm, and the reflectivity of the first color layer 422 is about 40% to 50%.

[0104] Example 2 (dashed line) relates to a sample with a different height and pitch of the lens pattern from Example 1 (solid line), showing the mixed color of the color evaporated layer (first color layer) on the front surface and the color evaporated layer (second color layer) on the rear surface and the resulting wavelength band (reflectivity of about 40% to 50% in the wavelength band of about 510nm to 550nm). Example 2 can show the mixed color of the front surface color evaporation and the rear surface color evaporation and the wavelength band of the lens pattern in the structure other than the depth or pitch. Example 3 relates to a sample when the reflectivity of the color evaporated layer (first color layer) on the front surface is lower than about 40% to 50%, showing the mixed color and wavelength band of the color evaporated layer (first color layer) on the front surface and the color evaporated layer (second color layer) on the rear surface.

[0105] Fig.10 is a diagram illustrating a method for manufacturing a housing of an electronic device according to an embodiment.

[0106] First, the shape and appearance of the electronic device are designed. The design and number of colors for achieving the appearance, color layout, and pattern to be observed can be determined. A base layer 410 for forming the pattern and color is prepared.

[0107] A first mold 501 having a first pattern 502 may be prepared to pattern the first surface 410a of the base layer 410. A UV curable resin R may be injected into the prepared first mold 501. The resin injected into the first mold 501 in a predetermined amount may be spread on the first pattern 502 of the first mold 501 when the base layer 410 is placed on the first pattern 502 of the first mold 501. The resin compressed by the first surface 410a of the base layer 410 and spread on the first mold 501 may be further compressed by a roller 503 moving on the base layer 410 to penetrate into the middle of the first pattern 502 of the first mold 501. In addition, the resin cured by the UV curing process may be attached to the first surface 410a of the base layer 410. A first pattern layer 421 may be formed on the first surface 410a of the base layer 410 by this process.

[0108] A second mold 601 having a second pattern 602 may be prepared to pattern the second surface 410b of the base layer 410. A UV curable resin R may be injected into the prepared second mold 601. The resin injected into the second mold 601 in a predetermined amount may be spread on the second pattern 602 of the second mold 601 when the base layer 410 is placed on the second pattern 602 of the second mold 601. The resin compressed by the second surface 410b of the base layer 410 and spread on the second mold 601 may be further compressed by a roller 603 moving on the base layer 410 to penetrate into the middle of the second pattern 602 of the second mold 601. In addition, the resin cured by the UV curing process may be attached to the second surface 410b of the base layer 410. A second pattern layer 431 may be formed on the second surface 410b of the base layer 410 by this process.

[0109] The first pattern layer 421 formed on the first surface 410a of the base layer 410 and the second pattern layer 431 formed on the second surface 410b of the base layer 410 may be formed in any order. According to an embodiment, the first pattern layer 421 may be first formed on the base layer 410, and then the second pattern layer 431 may be formed. Conversely, the second pattern layer 431 may be first formed, and then the first pattern layer 421 may be formed. Alternatively, after forming the first pattern layer 421 on the base layer 410 and forming the second pattern layer 431 on the other base layer 410, the two base layers 410 may be stacked so that the unpatterned surfaces of the two base layers 410 face each other.

[0110] The housing 400 (accessory cover or decorative film) may be manufactured in which a first color layer 422 and / or a second color layer 432 may be formed on the surface of the first pattern layer 421 and / or the second pattern layer 431 by an evaporation process in a base layer 410 having a first pattern layer 421 and / or a second pattern layer 431. The color layer may be formed by exposing the base layer 410 having the first pattern layer 421 and / or the second pattern layer 431 to an evaporator 701. The first color layer 422 and / or the second color layer 432 may include at least one color. According to an embodiment, it may be formed as a multicolor layer having a plurality of colors. The housing 400 may be formed to have a desired size and shape via an additional process (e.g., a forming or printing process using a molding machine (e.g., a mold 702) on the base layer 410 having the first pattern layer 421 and / or the second pattern layer 431 and the first color layer 422 and / or the second color layer 432).

[0111] Return to reference Figure 4 The housing 400 of the electronic device 101 may further include a glass 440 (eg, a glass layer) and an adhesive layer 450 .

[0112] The glass 440 may be formed on one surface of the first visible layer 420, and may form the outermost material of the housing 400. The adhesive layer 450 may be formed on the rear surface of the glass 440 to maintain adhesion with the first visible layer 420.

[0113] The housing 400 of the electronic device 101 may further include a shielding printed layer 460. The shielding printed layer 460 may be formed of an opaque material and may be disposed on the rear surface of the second visible layer 430 to prevent internal components of the electronic device 101 from being visible to the outside.

[0114] Fig.11a , Fig.11b and Fig.11c is a diagram showing a housing of an electronic device according to an embodiment of the present disclosure. As an embodiment, Fig.11a It can be shown that light is incident on the housing 400 and then refracted and / or reflected in a first illumination environment of 500 to 600 Lux. As an example, Fig.11b Light incident on the housing 400 and then refracted and / or reflected in a second illumination environment of 1000 to 1500 lux may be shown. As an example, Fig.11c Light that is incident on the housing 400 and then refracted and / or reflected in the third illumination environment of 2000 lux or more may be illustrated.

[0115] refer to Figures 11a to 11c , electronic devices (e.g. Figure 1 The electronic device 101 may include a housing 400 including a base layer 410, a first visible layer 420, and a second visible layer 430.
