Description

Wearable electronic device comprising a lens assembly

[0001] The descriptions below relate to a wearable electronic device including a lens assembly.

[0002] Portable electronic devices, such as electronic notebooks, portable multimedia players, mobile communication terminals, and tablet PCs, typically feature display elements and batteries, and have typically had bar-shaped, folder-shaped, or sliding-type appearances due to the shape of the display elements or batteries. Recently, as the performance of display elements and batteries has improved, these devices have become smaller, leading to the emergence of electronic devices that can be worn on parts of the body, such as the wrist or head, or in the form of clothing (hereinafter referred to as "wearable electronic devices").

[0003] Examples of wearable electronic devices include head-mounted devices (HMDs), smart glasses, smart watches (or bands), contact lens-type devices, ring-type devices, and clothing / shoe / glove-type devices. These body-worn electronic devices are easy to carry and can improve user accessibility.

[0004] For example, a 'head-mounted wearable device' is a device worn on the user's head or face, and is a device that projects an image onto the user's retina to enable the user to view a virtual image in a three-dimensional space. For example, head-mounted wearable devices can be divided into see-through types that provide augmented reality (AR) and see-closed types that provide virtual reality (VR). A see-through type head-mounted wearable device can be implemented in the form of glasses, for example, and can provide the user with information such as buildings and objects in the space within the user's field of vision in the form of images or text. A see-closed type head-mounted wearable device can output independent images to both eyes of the user, and can provide the user, or one person, with an excellent sense of immersion by outputting content (such as games, movies, streaming, and broadcasting) provided by a mobile communication terminal or an external input in the form of images or audio. Additionally, head-mounted wearable devices may be used to provide mixed reality (MR) or extended reality (XR), which are a combination of augmented reality (AR) and virtual reality (VR).

[0005] Recently, product development for head-mounted wearable devices has been actively underway, and they are being used for a variety of purposes, including military, gaming, industrial, and medical applications. Consequently, there is a growing demand for smaller, lighter devices while also providing superior image quality.

The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0050] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate.

The first lens (411) may control the focal length electronically without mechanical movement. The wearable electronic device (300) of the present disclosure includes a first lens (411) that can control the focal length electronically, so that not only a physical distance movement but also an electronically fine diopter adjustment can be performed. According to one embodiment, when the position of the first barrel (420) moves, the first lens (411) The position of the lens (411) can also be moved correspondingly. When the position of the first lens (420) is moved, the distance between the first lens (411) and the second lens (412) changes, which can affect the diopter adjustment.

[0120] In one embodiment, the first lens (411) can be moved to a preset value when its position is moved. Then, in a fine adjustment operation, the diopter can be adjusted using software.

[0121] According to one embodiment, the first barrel (420) may include a wheel (not shown) for adjusting the diopter of the lens. The wheel located on the 1-3 surface (420c) of the first barrel (420) may be formed so that at least a portion of the wheel is exposed through an opening (not shown) formed in the second barrel (430).
