Description

Facade member and electronic device including same

Various embodiments disclosed in this document relate to an electronic device, for example, to an exterior member and an electronic device including the same.

As electronics, information, and communication technologies develop, various functions are being integrated into a single electronic device. For example, a smart phone includes functions such as a sound reproducing device, an imaging device, or an electronic notebook as well as a communication function, and more various functions may be implemented in the smart phone through the additional installation of an application. The electronic device may access a server or another electronic device in a wired or wireless manner, as well as execute a loaded application or a stored file, and receive various information in real time.

As the portability and use of electronic devices such as a smart phone become commonplace, users' demands for the appearance of electronic devices are diversifying. In response to various user needs, the housing can be made of a variety of materials such as metal, glass, or ceramic, and various touches and colors can be realized on the exterior of electronic devices through processes such as surface treatment or painting of the housing. I can.

As the number of materials used to manufacture one exterior member (e.g., housing) increases, or as processes such as surface treatment or painting are added, manufacturing costs may increase as manufacturers must have more equipment. . An increase in manufacturing cost leads to an increase in product prices, which can increase the economic burden on consumers. In the finishing process such as surface treatment or painting of exterior members, the screen printing method has high color reproduction and productivity, and the equipment cost is low even for the production of different types of products, so it will be useful for adding processes such as surface treatment and painting. I can.

A painting that implements a gradation effect on the exterior of a product such as an electronic device can provide more various colors and visual effects according to a combination of colors. For example, in the exterior member, at least one printed layer gradually increases or decreases the size of printed dots along a certain direction, thereby implementing the effect of gradually changing the color or color density on the surface of the exterior member. Can be. However, there may be limitations in implementing gradation using a screen printing method that is cheap and highly productive. For example, when the minimum size (or minimum diameter) of the printing dot(s) is about 100*100 micrometers (um), natural gradation can be realized with the naked eye, but the minimum size of paint particles used for screen printing Can be greater than this. For example, there may be limitations in implementing a natural gradation effect by using the screen printing method. Even if the minimum size of the paint particles is smaller than this, clogging may occur in the printing screen due to the viscosity of the paint. Since such clogging occurs irregularly, the gradation reproducibility is lowered, and product quality may vary depending on the time of manufacture. For example, with a general screen printing method, it may be difficult to form printed dot(s) of 100*100 micrometers or less, and it may be difficult to manufacture an external member of uniform quality or an electronic device including the same.

According to various embodiments disclosed in this document, it is possible to provide an external member and/or an electronic device including the exterior member that is manufactured by a screen printing method and realizes a natural gradation effect to the naked eye.

According to various embodiments disclosed in this document, it is possible to provide an exterior member and/or an electronic device including the exterior member having uniform appearance quality while being manufactured at low cost and implementing natural gradation.

According to various embodiments disclosed in this document, printing patterns of different printing layers may be combined to implement printing dot(s) having a size of at least 20*35 micrometers. For example, since printing dots of various or fine sizes can be implemented, a more natural gradation can be implemented on the exterior member or the exterior of the electronic device. According to an embodiment, the printing patterns of each printing layer have a line and/or band shape that extends substantially along a predetermined direction, and thus, it may be easy to form by a screen printing method. For example, clogging of a printing screen for forming each printing layer can be improved, and uniform quality between products can be ensured. In another embodiment, a hole pattern of a printing screen for forming line and/or strip-shaped printing patterns is extended along a predetermined direction, and a direction in which the hole pattern of the printing screen is extended is substantially squeegee. ) May be the same as the direction of movement. For example, it is possible to improve quality deterioration due to bleeding of paint at the edges of printed patterns.
