Wearable electronic device including a light-emitting module
[0001] Embodiments of the present disclosure relate to a wearable electronic device including a light-emitting module.
[0002] Electronic devices may include wearable electronic devices that can be worn on a part of a user's body to enhance portability or accessibility. Wearable electronic devices may include ear-worn electronic devices that are worn on the user's ear to enable listening to music or provide convenient phone calls. Ear-worn electronic devices may include a light-emitting region that is positioned so as to be visible from the outside to provide notification information to the user. Such light-emitting regions may require a layout structure that contributes to the aesthetic appearance of the ear-worn device.
[0003] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the present disclosure.
[0004] A wearable electronic device (e.g., an ear-worn wearable electronic device) may include at least one light-emitting module (e.g., a light-emitting structure, an LED indicator, or a light-emitting body) disposed in at least a portion of a housing and visible from the outside. For example, the light-emitting module may provide a user with status information of the ear-worn wearable device by emitting light in various forms.
[0005] The light-emitting module may further include a light-emitting element (e.g., an LED) positioned within the interior of the wearable electronic device and an indicator made of a light-transmitting material incorporated into a specific region of the housing. When such an indicator is coupled to the housing, light leakage may occur due to gaps or gaps resulting from assembly tolerances, thereby damaging the appearance of the wearable electronic device. Furthermore, the gaps between the two components may allow foreign substances and / or moisture to enter, making the device vulnerable to waterproofing and / or stain resistance.
[0006] Various embodiments of the present disclosure can provide a wearable electronic device including a light-emitting module that can help form an attractive appearance by forming a light-emitting region through which internal light can be emitted through at least a portion of the housing.
[0007] Various embodiments may provide a wearable electronic device including a light-emitting module that may aid in waterproofing and / or stain resistance by providing a light-emitting area solely through the structure of the housing without a separate indicator arrangement.
[0008] However, the problem to be solved in this disclosure is not limited to the problem mentioned above, and may be expanded in various ways without departing from the spirit and scope of this disclosure.
[0009] According to various embodiments, a wearable electronic device includes a housing formed of a transparent or translucent material and a light-emitting module disposed in a first internal space of the housing and arranged to emit light to the outside through a first outer surface of the housing, wherein the housing includes an opaque first layer formed on a second outer surface excluding the first outer surface and a transparent or translucent second layer formed on at least the first outer surface, wherein the first outer surface may protrude relatively more than the second outer surface. Various other embodiments may be possible.
[0010] According to various embodiments, a method for forming a light-emitting area disposed on an outer surface of a wearable electronic device may include a first operation of forming an opaque first layer on an outer surface of a transparent or translucent housing base material, a first operation of removing the first layer in an area corresponding to the light-emitting area, and a third operation of forming a transparent or translucent second layer in the first layer and an area from which the first layer has been removed.
[0011] According to exemplary embodiments of the present disclosure, a wearable electronic device may be provided with a light-emitting region in a single housing through only a painting process and a film-removal process, in which an opaque first layer is applied to the outer surface of a housing, and in a specific region, the first layer is removed, and then a transparent second layer is formed, including the first layer and the film-removal region. Since this light-emitting region is formed in a single housing without requiring a separate indicator (e.g., an indicator structure), this may help form an attractive appearance of the wearable electronic device, and may be advantageous in waterproofing and / or stain resistance.
[0012] In addition, various effects may be provided, either directly or indirectly, through this document.
[0013] The effects that can be obtained from the present disclosure are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure belongs from the description below.

In one embodiment, the molding layer may be cured through a process of oven or natural drying or through an ultraviolet curing method.
[0080] In some embodiments, a primer layer (P) may be formed before each layer (e.g., the shielding layer (311), the color layer (312), and the second layer (320)) is applied. In one embodiment, the primer layer (P) may induce uniform and smooth application and adhesion of each layer to its underlying layer. In one embodiment, the primer layer (P) may be formed by spraying using a SiO2-based solvent such as a glass component or an acrylic urethane. In some embodiments, the primer layer (P) may be formed using a transparent urethane paint.
