Description

Wearable electronic devices including displays

[0001] Examples disclosed in this document relate to wearable electronic devices including displays.

[0002] Portable electronic devices, such as electronic notebooks, portable multimedia players, mobile communication terminals, and tablet PCs, typically feature a display device (or display module) and a battery. Due to the shape of the display device or battery, they typically have a bar-shaped, folder-shaped, or sliding-type appearance. Recently, as the performance of display devices and batteries has improved, they 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 as clothing (hereinafter referred to as "wearable electronic devices").

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

[0004] For example, a head-mounted wearable device is a device worn on the user's head or face that projects an image onto the user's retina, allowing the user to view virtual images in three-dimensional space. For example, head-mounted wearable devices can be categorized 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 about 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 (games, movies, streaming, 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.

[0040] The following description, with reference to the accompanying drawings, is provided to facilitate a comprehensive understanding of various embodiments of the present invention as defined by the claims and their equivalents. While this description includes numerous specific details to facilitate this understanding, they are to be considered merely exemplary. Accordingly, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present invention. Furthermore, descriptions of well-known functions and configurations may be omitted for clarity and conciseness.

[0041] The terms and words used in the following description and claims are not intended to be limited by their bibliographic meanings, but are merely used by the inventors to facilitate a clear and consistent understanding of the present invention. Therefore, it will be apparent to those skilled in the art that the following description of various embodiments of the present invention is provided for illustrative purposes only and is not intended to limit the scope of the present invention, which is defined by the appended claims and their equivalents.

[0042] The singular forms "a," "an," and "the" should be understood to include the plural unless the context clearly indicates otherwise. Thus, for example, reference to "a component surface" includes reference to one or more of those surfaces.

[0043] Wearable electronic devices that implement augmented reality, virtual reality, mixed reality, and / or extended reality can generally be used while worn on the user's head or face. For example, a display that outputs images or visual information in the form of light can be positioned at a relatively close distance from the user's eyes. When the display and the user's eyes are positioned at a relatively close distance, it can be difficult to configure an optical system that guides or focuses the light to the user's eyes. For example, the size or number of lenses may be limited to minimize the size or weight of the wearable electronic device, and it may be difficult to implement an optical system that can provide good image quality with a limited number of lenses. In one embodiment, in a usage environment where the display and the user's eyes are positioned at a relatively close distance, an optical system with a pancake lens structure can be useful for providing good image quality while using a limited number of lenses. The optical system with a pancake lens structure can implement an optical path that is sufficiently long compared to the mechanical length (e.g., the total length of the lens) by reflecting the light output from the display at least twice as it passes through the path to the user's eyes. The pancake lens structure can provide excellent image quality while being compact. However, the repeated reflection structure can increase light refraction and scattering. For example, when light refraction and scattering increase, interference between refracted and scattered light can result in a deterioration in image quality.

[0044] One embodiment of the present disclosure is intended to at least resolve the above-described problems and / or disadvantages and at least provide the advantages described below, thereby providing a wearable electronic device including a lens assembly that is easy to control aberrations and thus realizes good image quality.

[0045] One embodiment of the present disclosure can provide a wearable electronic device including a miniaturized and / or lightweight lens assembly while providing good image quality.

[0046] One embodiment of the present disclosure can provide a wearable electronic device that can reduce user fatigue when worn by being miniaturized and / or lightweight.

[0047] The technical problems to be achieved in this document are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present disclosure belongs from the description below.

[0048] The following description of the accompanying drawings may provide an understanding of various exemplary implementations of the present disclosure, including the claims and their equivalents. While the exemplary embodiments disclosed in the following description include numerous specific details to aid understanding, they are to be considered as one example of various exemplary embodiments. Accordingly, those skilled in the art will appreciate that various modifications and variations of the various implementations described herein may be made without departing from the scope and spirit of the disclosure. Furthermore, descriptions of well-known functions and configurations may be omitted for clarity and conciseness.

[0049] The terms and words used in the following description and claims are not limited to their reference meanings and can be used to clearly and consistently describe one embodiment of the present disclosure. Therefore, it will be apparent to those skilled in the art that the following description of various implementations of the disclosure is provided for illustrative purposes, not for the purpose of limiting the scope of the disclosure and its equivalents.

[0050] Unless the context clearly dictates otherwise, the singular forms of "a," "an," and "the" should be understood to include plural meanings. Thus, for example, "a component surface" could be understood to include one or more of the surfaces of the component.

[0051] It should be understood that each block of the flowchart and the combination of flowcharts can be performed by one or more computer programs containing computer-executable instructions. One or more computer programs may be stored entirely in a single memory device, or one or more computer programs may be divided into multiple parts and stored in multiple different memory devices.

In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)). In one embodiment, the auxiliary processor (123) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (101) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (108)). The learning algorithm can include, for example, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, but is not limited to the examples described above. The artificial intelligence model can include multiple artificial neural network layers.The artificial neural network may be one of a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent deep neural network (BRDNN), a deep Q-network, or a combination of two or more of the above, but is not limited to the examples described above.

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).

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).

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.

In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0073] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0074] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In one embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

[0128] In the present disclosure, the wearable electronic device (500) may be configured to move the first display (501) and the second display (502) within a range of movement (D) such that the center (P1) of the first display (501) and the center (P2) of the second display (502) are aligned with the center of the pupil of the left eye and the center of the pupil of the right eye of the user, respectively. In other words, in the present disclosure, the wearable electronic device (500) may be configured to move the first display (501) and the second display (502) within the range of movement (D) such that the center spacing (E) of the first display (501) and the second display (502) is similar to or corresponds to the distance between the centers of the pupils of both eyes of the user. For example, the range of movement (D) may be designed or set in consideration of the center spacing (E) being the distance between the centers of the pupils of both eyes of a typical user (or the interocular distance). For example, the center spacing (E) may be set to change in a range of about 55 mm to about 75 mm, and the movement range (D) may be set to about 10 mm. In this case, the minimum value d1 of the center spacing (E) shown in FIG. 10a may be about 55 mm, and the maximum value d2 of the center spacing (E) shown in FIG. 10b may be about 75 mm. For example, the center spacing (E) may be set to change in a range of about 60 mm to about 70 mm, and the movement range (D) may be set to about 5 mm. However, the above-described values ​​are not limited and may be freely designed and changed.

For example, in the section where the magnetic force linearly changes between S1 and S2 of FIG. 10c, the magnitude of the magnetic force can correspond to the positions of the first and second displays (501, 502), and accordingly, the positions of the first and second displays (501, 502) can be identified. In FIGS. 11A and 11B, the vertical axis may represent the distance (unit: mm) between the centers (P1, P2) of the first and second displays (501, 502) and the center (O) of the wearable electronic device (500), and the horizontal axis may represent the magnetic force (unit: Tesla (T)) detected by the first and second Hall sensors (572, 582). The wearable electronic device (500) according to the embodiment(s) of the present disclosure may detect the relative positions of the first and second Hall sensors (572, 582) and the first and second magnetic members (571, 581) from the magnetic force detected by the first and second Hall sensors (572, 582). On the horizontal axis, when the magnetic force is 0 (T), it may correspond to a state in which the centers of the first and second hall sensors (572, 582) and the centers of the first and second magnetic members (571, 581) are aligned. On the horizontal axis, when the magnetic force is +2.5 (T), it may correspond to a state in which the first and second displays (501, 502) are most closely arranged, and when the magnetic force is -2.5 (T), it may correspond to a state in which the first and second displays (501, 502) are most closely arranged. However, the numbers of the vertical and horizontal axes of FIGS. 11A and 11B are merely examples and are not limiting.

[0169] Referring to FIG. 20b, in one embodiment, the operation (13) of detecting the coordinates of the centers of the user's pupils using the first and second displays (501, 502) and the cameras (or the first and second cameras) (515, 516) may include the operation (331) of displaying an image guiding the user's gaze on the first and second displays (501, 502), the operation (332) of photographing the user's eyes with the cameras (515, 516), and the operation (333) of detecting the coordinates of the centers of the user's pupils based on the images photographed with the cameras (515, 516).

[0170] According to one embodiment, in the operation (34) of calculating the distance from the center (P1, P2) of the first and second displays (501, 502) to the coordinates of the centers of the user's pupils, as described above, the "distance from the center (P1, P2) of the first and second displays (501, 502) to the centers of the user's pupils" may mean the distance (or straight-line distance, shortest distance) from the center (P1) of the first display (501) to the center of the pupil of one eye (e.g., left eye) of the user facing the first display (501), and the distance from the center (P2) of the second display (502) to the center of the pupil of the other eye (e.g., right eye) of the user facing the second display (502).

[0171] According to one embodiment, in the operation (35) of determining whether the sum of the calculated left-right distance differences exceeds the second specified distance, the “sum of the calculated left-right distance differences” refers to the sum of the difference in distance between the coordinates of the centers of the user’s two pupils aligned with (or corresponding to) the initial positions of the stored first and second displays (501, 502) and the coordinates of the centers of the user’s two pupils detected in the operation (33), which may be the sum of the displacement of the center of the pupil of the left eye and the displacement of the center of the pupil of the right eye. For example, the operation (35) may be performed by the processor (542). According to one embodiment, the second specified distance may be about 1.5 mm or more and about 2.5 mm or less, or about 1.8 mm or more and about 2.2 mm or less, and may be about 2 mm as an example.

[0172] According to one embodiment, in the operation (37) of determining whether the sum of the left-right differences between the current positions of the first and second displays (501, 502) and the stored initial positions exceeds a third specified distance, the “sum of the left-right differences” may mean the sum of the difference (left difference or first difference) between the current position of the first display (501) and the stored initial position and the difference (right difference or second difference) between the current position of the second display (502) and the stored initial position. In the operation (37), if the sum of the left-right differences exceeds the third specified distance, the wearable electronic device (500) (e.g., the processor (542)) may determine that the current positions of the first and second displays (501, 502) are different from the stored initial positions. The third specified distance may be, in one embodiment, about 1.5 mm or more and about 2.5 mm or less, or about 1.8 mm or more and about 2.2 mm or less, and as an example, about 2 mm.

[0173] Referring to FIGS. 20A and 19B, according to one embodiment, the operation (38) of recommending to the user to adjust the positions of the first and second displays (501, 502) may be implemented as a UI in which a phrase recommending to adjust the positions of the displays (501, 502) is displayed on the first and second displays (501, 502) as illustrated in FIG. 19B, but is not limited thereto, and may be implemented in various ways of delivering a recommendation message to the user, such as voice guidance.

[0174] Referring to FIGS. 20A and 20C , according to one embodiment, an operation (39) of recommending to a user to wear a wearable electronic device (or apparatus) (500) normally using the first and second displays (501, 502) may be implemented as a UI displaying a phrase recommending to adjust the proper wearing of the device as illustrated in FIG. 20C , but is not limited thereto, and may be implemented in various ways of delivering a recommendation message to the user, such as voice guidance. In the control method described above with reference to FIGS. 20A to 20C , some operations may be omitted or other operations may be added.

[0175] Conventionally, head-mounted wearable electronic devices (or devices) can be configured to manually adjust the inter-pupillary distance (IPD). However, conventional head-mounted wearable electronic devices may not generally provide a function for detecting the current positions of the first and second displays corresponding to the user's pupils. In such cases, when a user first puts on the device, the positions of the first and second displays are initially set to correspond to the inter-pupillary distance for the user's pupils. Even if the positions of the first and second displays are unintentionally moved from the initially set positions during use of the device, it may be difficult to recognize this. For example, examples of cases in which the positions of the first and second displays are unintentionally moved from the initially set positions include cases in which at least one of the first and second displays is moved due to a factor such as an external impact while the user is wearing the device, or cases in which the user does not put the device on properly after taking it off and putting it back on.

[0176] For example, if the positions of the first and second displays are unintentionally moved from their initial positions, the user's pupils may not be aligned with the centers of the first and second displays, and in this case, the user may experience increased fatigue when using the device. In cases where the current positions of the first and second displays cannot be measured, as in existing head-mounted wearable electronic devices, there is a problem in that it is difficult for the user to recognize that the positions of the first and second displays need to be readjusted.

[0177] Aspects of the present disclosure are intended to solve at least the problems and / or disadvantages described above, and to provide at least the advantages described below. A wearable electronic device (500) according to an embodiment(s) of the present disclosure may be configured to adjust an inter-pupillary distance (IPD). A wearable electronic device (500) according to an embodiment(s) of the present disclosure may measure the positions of the first and second displays (501, 502) using a position measuring assembly (570, 580), thereby detecting a state in which the first and second displays (501, 502) are unintentionally moved after the user wears the wearable electronic device (500) or a state in which the user wears the wearable electronic device (500) incorrectly, and may provide a function of notifying the user of these states. The wearable electronic device (500) (or device) of the present disclosure notifies the user when the positions of the first and second displays (501, 502) are unintentionally moved from their initially set positions, thereby allowing the user to readjust the positions of the first and second displays to a correct wearing state, that is, so that the user's pupils are aligned with the centers of the first and second displays, thereby reducing user fatigue and providing a comfortable use environment when using the device.
