Description

Case and electronic device including same

BACKGROUND ART With the remarkable development of information and communication technology and semiconductor technology, the dissemination and use of various electronic devices are rapidly increasing. In particular, recent electronic devices are being developed to be portable and to be able to communicate.

An electronic device is a device that performs a specific function according to a loaded program, such as an electronic notebook, a portable multimedia player, a mobile communication terminal, a tablet PC, an image/audio device, a desktop/laptop computer, and a vehicle navigation device from a home appliance can mean For example, these electronic devices may output stored information as sound or image. As the degree of integration of electronic devices increases and high-speed and large-capacity wireless communication becomes common, various functions may be mounted in one electronic device such as a mobile communication terminal in recent years.

Such electronic devices are being miniaturized so that users can conveniently carry them.

Recently, as miniaturization, thinness, and portability of portable electronic devices such as smart phones are emphasized, there is a need to improve the appearance of the electronic device in design, while improving antireflection effect and abrasion resistance performance.

As an anti-reflection film of a general case used in an electronic device, a multilayer thin film using the interference effect of a high refractive index material and a low refractive index material may be used. The antireflection film formed of the multilayer thin film may require a lot of coating time and cost to form a thick thin film. In addition, as the uppermost layer is coated with a low-refractive material (eg, an oxide film) in order to realize the advantageous effect of the anti-reflection film, the surface hardness may be reduced. Reduced surface hardness can cause peeling or damage of the thin film. In addition, the antireflection film formed as a multilayer thin film has an antireflection effect only for a specific viewing (night) angle (eg, based on 90 degrees) depending on the refractive index and coating thickness, and the antireflection effect decreases as the viewing (night) angle increases. and visibility may be reduced.

According to various embodiments of the present disclosure, an anti-reflection (AR) film used in the case may be configured as a single layer, thereby reducing manufacturing time and cost.

According to various embodiments of the present disclosure, as the anti-reflection film used for the case uses a single high-hardness thin film layer (eg, a single-layer structure), it is possible to prevent damage to the thin film and lower the visual visibility of the damaged surface.

According to various embodiments of the present disclosure, the anti-reflection film used in the case may form a concave-convex structure pattern on a portion of the high-hardness single thin film layer to improve display visibility.

According to various embodiments of the present disclosure, as the anti-contamination layer is disposed on a surface on which the concave-convex structure pattern is formed on a part of the high-hardness single thin film layer of the anti-reflection film used in the case, the wear resistance of the anti-pollution layer may be improved.

An electronic device according to various embodiments of the present disclosure may include a display, a transparent plate disposed on the display, and a single thin film layer disposed on one surface of the transparent plate. The thin film layer includes a first thin film region having a hardness equal to or greater than the transparent plate hardness and forming a first specified thickness, and a second thin film having a second specified thickness formed on the first thin film region and including a concave-convex structure pattern having a curvature. It may contain areas.

An electronic device according to various embodiments of the present disclosure includes a case that forms at least a part of an exterior of the electronic device, a battery disposed in an inner space of the case, and a battery disposed in the inner space and transmits information to the outside It may include a display for displaying. The case includes a glass plate disposed on the display, a thin film layer disposed on one surface of the glass plate, in which an uneven structure pattern having a curvature is formed in an upper region facing the opposite side of the glass plate, and contamination disposed on the thin film layer It may include a protective layer for prevention.

A case according to various embodiments of the present disclosure includes a glass plate, a thin film layer disposed on one surface of the glass plate, a first thin film region having a hardness greater than or equal to the glass plate hardness, and a dry or wet etching process on the first thin film region It may include a thin film layer formed by and including a second thin film region including a concave-convex structure pattern having a curvature, and an anti-contamination layer disposed on the thin film layer.

The case of the electronic device according to various embodiments of the present disclosure may include an anti-reflection (AR) film having a single-layer structure.

Since the case of the electronic device according to various embodiments of the present disclosure uses a single high-hardness thin film layer (eg, a single-layer structure), it is possible to prevent damage to the thin film and lower the visual visibility of the damaged surface.

In the case of the electronic device according to various embodiments of the present disclosure, an anti-reflection effect and display visibility may be improved by forming a concave-convex structure pattern on a portion of the high-hardness single thin film layer.

In the case of the electronic device according to various embodiments of the present disclosure, a protective layer may be coated on a portion of the high-hardness single thin film layer on the concave-convex structure pattern. Surface contact of the protective layer is increased by the concave-convex structure pattern, so that mechanical adhesion of the protective layer is improved, and thus, anti fingerprint (AF) performance can be improved.

For example, the hardness of the first thin film region 520a may be higher than that of the transparent plate 510 . As another example, the first thin film region 520a may have a hardness higher than that of the tempered glass, for example, Vicker's hardness 200 g load, 650 kgf/mm ² or more.

According to an embodiment, the first thin film region 520a may correspond to a lower region of the thin film layer 520 and may form a first specified thickness. The first specified thickness of the first thin film region 520a may be smaller than the thickness of the transparent plate 510 . According to some embodiments, the first thin film region 520a has an optical transmittance of 70% or more and may be designed with at least one of nitride, oxide nitride, DLC, ZnO, or SiH having a hardness higher than that of chemically strengthened glass. .

According to one embodiment, the second thin film region 520b is formed by using at least one of a wet or dry etching method on at least a portion of the surface of the thin film layer 520 on which the process for forming the first thin film region 520a is completed, It may be a thin film formed to have a thickness of several tens of nm to several thousand nm.

The second specified thickness of the second thin film region 520b may be different from the first specified thickness of the first thin film region 520a. For example, the second specified thickness may be less than the first specified thickness.

According to an exemplary embodiment, the second thin film region 520b may be positioned on the first thin film region 520a to form a concave-convex structure pattern P having a curvature. For example, the concave-convex structure pattern P having a curvature may be formed by an arrangement of a plurality of protruding portions forming a curvature having a slope that decreases as the distance from the transparent plate 510 increases. As another example, the concave-convex structure pattern P having a curvature, when viewed from the top of the thin film layer 520 (when viewed in the -Z direction), is spaced apart from each other and has a plurality of structures formed of at least a circular or oval shape. may be in the form of As another example, the concave-convex structure pattern P having the upper curvature may be an arrangement of hemispherical shapes protruding upward with respect to the upper surface of the first thin film region 520a.

For example, the patterning of the concave-convex structure having a fine curvature disposed on the surface of the first thin film region 520a may form a curvature to be inclined outwardly from the first thin film region 520a. According to the curvature, the surface refractive index is lower than that of the transparent plate, and thus, it is possible to provide an anti-reflection effect in the visible light region.

According to various embodiments, the protective layer 540 may be formed on the outer surface of the case 500 and may prevent contamination of the external environment by dust or oil. In an embodiment, the protective layer 550 may be formed of a substantially transparent material to allow external light to be incident to the inside.

For example, a plurality of concave-convex structures are formed on the outer surface of the protective layer 550 to reduce an area in contact with the user's finger, thereby reducing contamination of the case 500 due to oil from the user's finger. As another example, the protective layer 540 exposes a surface protruding to the outside according to the plurality of concavo-convex structures, so that when a user touches it, it provides a texture that can be felt and prevents water repellency and/or fingerprint prevention. can provide

According to an embodiment, the configuration of the process 4000 may be excluded according to the operator's selection. In FIG. 6 , the protective layer 540 is shown in the form of a chemical bond combined with the second thin film region 520b.

According to various embodiments, the electronic device (eg, the electronic device 101 of FIGS. 1 to 4 ) includes a case 500 (eg, the housing of FIGS. 2 to 3 ) that forms at least a part of the exterior of the electronic device 101 . (310))). For example, the case 500 may be the same as some or all of the front plate 310A, the rear plate 310B, or the side bezel structure 318 of FIGS. 2 and 3 .

The case 500 may include a transparent plate 510 , a thin film layer 520 , and a protective layer 540 , and the thin film layer 520 includes a first thin film region 520a and a second thin film region 520b . can be The configuration of the transparent plate 510 , the thin film layer 520 , and the protective layer 540 of FIG. 8 is the same as the configuration of the transparent plate 510 , the thin film layer 520 , and the protective layer 540 of FIGS. 5 to 7 . or all may be the same.

According to various embodiments, the protective layer 540 is disposed on the second thin film region 520b of the thin film layer 520 and is implemented as a fine thin film to be manufactured in a shape corresponding to the shape of the second thin film region 520b. can The protective layer 540 is formed on the concave-convex structure pattern P having the fine curvature of the two thin film regions 520b and is coated to surround the outer surface of the case, thereby improving anti-contamination performance. In addition, the protective layer 540 comes into contact with the concave-convex structure pattern P having a fine curvature of the second thin film region 520b of the thin film layer 520 , so that mechanical adhesion can be increased, and thus, high reflection prevention (AR; anti reflection) coating can be provided. For example, the concave-convex structure pattern P of the second thin film region 520b includes a plurality of concavo-convex structures protruding toward the thin film layer 540 , and the protective layer 540 penetrates into a gap between the plurality of concavo-convex structures. Accordingly, an area in contact with the thin film layer 520 may be increased. Accordingly, a structure in which mechanical adhesion is improved may be provided, and anti-reflection (AR) performance may be improved.

According to various embodiments, in the structure of the case stacked by the second thin film region 520b and the protective layer 540 of the thin film layer 520 , anti fingerprint (AF) performance may be improved.

It can be seen that the average AF performance coated with other AF companies' chemicals, for example, the number of contact times in the abrasion resistance test is about 5000 to 7,000 times on average. It can be seen that the moss-eye patterned AF performance according to the present disclosure is approximately 24,000 times.

9A is a view illustrating peeling off a case (eg, a thin film layer having a single-layer structure) forming at least a portion of a housing of an electronic device according to one of various embodiments of the present disclosure; 9B is a view illustrating peeling off a case (eg, a thin film layer having a multi-layer structure) forming at least a portion of a housing of a general electronic device.

The case may include a transparent plate (eg, the transparent plate 510 of FIG. 5 ), a thin film layer (eg, the thin film layer 520 of FIG. 5 ), and a protective layer (eg, the protective layer 540 of FIG. 5 ). , the thin film layer may include a first thin film region (eg, the first thin film region 520a of FIG. 5 ) and a second thin film region (eg, the second thin film region 520b of FIG. 5 ). The thin film layer 520 may be a thin film forming one layer.

Referring to FIG. 9B , the thin film layer used in the general case 500 uses a multi-layer thin film layer to take advantage of the interference effect of the high refractive material and the low refractive material. In the multilayer thin film layer, the reflectivity can be adjusted according to the increase in the thin film stacking structure, and a considerable number of thin film layers and thick thicknesses are formed for AR effect above a certain level, which may require a lot of time and cost. In addition, in order to improve the AR effect, as the uppermost layer is coated with a low-strength material (eg, an oxide film), the surface hardness may be reduced. A part of the thin film layer may be easily peeled off by abrasion, and the visual visibility of the damaged area may be increased due to the difference in surface reflectance between the normal surface and the damaged surface.

Referring to FIG. 9A , according to various embodiments of the present disclosure, the thin film layer of the case may be formed as a single thin film layer. As the surface of the high-hardness thin film layer on which the concave-convex structure pattern with curvature is formed is formed as a single-layer thin film, there is no peeling of some thin films from the surface, and even if damaged or worn, the difference in surface reflectance does not occur significantly, so the visual visibility of the damaged area is lowered and AR performance persistence can be maintained.

The thin film region 520a) and a second thin film region (eg, the second thin film region 520b of FIG. 5 ) may be included. The thin film layer 520 may be a thin film forming one layer.

The thin film layer used in a general case uses a multi-layer thin film layer to take advantage of the interference effect of the high refractive material and the low refractive material. In the multilayer thin film layer, the reflectance according to the incident angle can be confirmed by L2 of FIG. 10B . In the multilayer thin film layer, the reflectivity rapidly increases according to the change of the incident angle, and the multilayer thin film layer may be a coating layer optimized for normal incidence of light (viewing angle of 90 degrees). Accordingly, when the case is viewed from the side (viewing angle is less than 90 degrees), visibility may be deteriorated.

The single thin film layer 520 used in the case 500 according to the present disclosure is a thin film layer on which the concavo-convex structure pattern P is formed. Due to the concavo-convex structures having a fine curvature, the surface refractive index may be lower than that of the glass plate 510 . The single thin film layer 520 can check the reflectance according to the incident angle by L1 of FIG. 10B . The single thin film layer 520 may maintain the basic reflectivity even if the incident angle increases as the dependence on the incident angle decreases. Accordingly, when the case is viewed from the side (the viewing angle is 90 degrees or less), the visibility does not deteriorate and the side visibility of the display can be increased.
