[0058] In one embodiment, when the display assembly (300) is formed of one of a liquid crystal display (LCD), a digital mirror display, or a silicon liquid crystal display (LCD), the wearable electronic device (200) may include a light source that irradiates light (e.g., visible light) to a screen output area of ​​the display assembly (300). In another embodiment, when the display assembly (300) can generate light (e.g., visible light) on its own, for example, when the wearable electronic device (200) is formed of one of an organic light-emitting diode (OLED) or a micro LED, the wearable electronic device (200) may not include a separate light source. For example, if the display assembly (300) is implemented with an organic light-emitting diode (OLED) or a micro LED, a light source is unnecessary, and thus the electronic wearable electronic device (200) may be lightweight.

[0059] According to one embodiment, the display assembly (300) may include a first display assembly (300a) and / or a second display assembly (300b). According to one embodiment, the first display assembly (300a) may be arranged to face the user's left eye in the fourth direction (④), and the second display assembly (300b) may be arranged to face the user's right eye in the third direction (③).

[0060] According to one embodiment, the display assembly (300) may include a lens assembly (e.g., lens assembly (440) of FIG. 3C) including a transparent waveguide. The lens assembly (440) may serve to adjust a focus so that a screen (e.g., XR content image) output from a display panel (e.g., display panel (420) of FIG. 3C) can be viewed by a user. For example, light (e.g., visible light) emitted from the display panel (420) may pass through the lens assembly (440) and be transmitted to the user through a waveguide formed within the lens assembly (440). The lens assembly (440) may include at least one of a Fresnel lens, a pancake lens, a convex lens, or a multi-channel lens.

[0061] In one embodiment, the first function cameras (e.g., recognition cameras) (215) can acquire images while the wearable electronic device (200) is worn by the user. The first function cameras (215) can be used for the purpose of detecting user movements or recognizing user gestures. For example, the first function cameras (215) can be used for at least one of hand detection, hand tracking, recognition of user gestures (e.g., hand movements), and / or space recognition. For example, the first function cameras (215) mainly use GS (global shutter) cameras, which have superior performance compared to RS (rolling shutter) cameras, to detect and track fine movements of hand movements and fingers, and can be configured as a stereo camera including two or more GS cameras for head tracking and space recognition. The first function cameras (215) can be used for 3DoF, 6DoF head tracking, location (spatial, environmental) recognition, and / or movement recognition. The first function camera (215) can perform simultaneous localization and mapping (SLAM) function to recognize information (e.g., location and / or direction) related to the surrounding space through spatial recognition for 6DoF and depth shooting. In one embodiment, the second function cameras (211, 212) can also be used for hand detection and tracking, and user gestures.

[0062] In one embodiment, the second function camera (e.g., a camera for shooting) (211, 212) can obtain an image related to the surrounding environment of the wearable electronic device (200). The second function camera (211, 212) can be used to shoot the outside and generate an image or video corresponding to the outside and transmit it to a processor (e.g., the processor (120) of FIG. 1). The processor (120) can display the image provided from the second function camera (211, 212) on the display assembly (300). The second function camera (211, 212) may also be referred to as an HR (high resolution) or PV (photo video) camera and may include a high-resolution camera. For example, the second function camera (211, 212) may include a color camera equipped with functions for obtaining high-quality images, such as an auto focus (AF) function and an optical image stabilizer (OIS), but is not limited thereto, and the second function camera (211, 212) may also include a GS camera or an RS camera.

[0063] In one embodiment, a third function camera (e.g., a gaze tracking camera) (228a, 228b) may be positioned on the display assembly (300) so that the camera lens faces the user's eyes when the user wears the wearable electronic device (200). The third function camera (228a, 228b) may be used for detecting and tracking pupils (ET) and / or recognizing the user's iris. The processor (120) may track the movements of the user's left and right eyes in the images received from the third function camera (228a, 228b) to determine the gaze direction. The processor (120) may track the position of the pupil in the images so that the center of the XR content image displayed in the screen display area is positioned according to the direction in which the pupil is gazing. As an example, the third function camera (228a, 228b) may be a GS camera that can detect pupils and track eye movements. The third function cameras (228a, 228b) may be installed for the left and right eyes, respectively, and cameras with the same performance and specifications may be used.

[0064] In one embodiment, the fourth functional camera (e.g., a face recognition camera) (225, 226, 227) may be used to detect and track (FT) the user's facial expression when the user wears the wearable electronic device (200). For example, the fourth functional camera (225, 226, 227) may be used to recognize the user's face, or to recognize and / or track the user's two eyes.

[0065] According to one embodiment, the depth sensor (or depth camera) (217) can be used for the purpose of checking the distance to an object (e.g., an object), such as TOF (time of flight). TOF (time of flight) is a technology that measures the distance to an object using a signal (e.g., near-infrared, ultrasound, or laser). After a signal is transmitted from a transmitter, a signal is measured at a receiver, and the distance to the object can be measured based on the flight time of the signal. For example, the depth sensor (217) can be configured to transmit a signal and receive a signal reflected from a subject. Instead of or in addition to the depth sensor (217), a first camera (215) can check the distance to an object.

[0066] According to one embodiment, the touch sensor (213) may be arranged in the second direction (②) of the housing (210). The touch sensor (213) may be implemented as a single type or a left / right separated type depending on the shape of the housing (210), but is not limited thereto. For example, when the touch sensor (213) is implemented as a left / right separated type as illustrated in FIG. 2A, when the user wears the wearable electronic device (200), the first touch sensor (213a) may be arranged at the user's left eye position, such as in the fourth direction (④), and the second touch sensor (213b) may be arranged at the user's right eye position, such as in the third direction (③).

[0067] In one embodiment, the touch sensor (213) can recognize a touch input in at least one of, for example, a capacitive, pressure-sensitive, infrared, or ultrasonic manner. For example, the capacitive touch sensor (213) can recognize a physical touch (or contact) input or a hovering input (or proximity) of an external object. According to some embodiments, the wearable electronic device (200) may utilize a proximity sensor (not shown) to enable proximity recognition of an external object.

[0068] According to one embodiment, the touch sensor (213) has a two-dimensional surface and can transmit touch data (e.g., touch coordinates) of an external object (e.g., a user's finger) that comes into contact with the touch sensor (213) to a processor (e.g., the processor (120) of FIG. 1). The touch sensor (213) can detect a hovering input for an external object (e.g., a user's finger) that approaches within a first distance from the touch sensor (213), or detect a touch input that touches the touch sensor (213).

[0069] According to one embodiment, the touch sensor (213) may provide two-dimensional information about the contact point as “touch data” to the processor (120) when an external object touches the touch sensor (213). The touch data may be described as a “touch mode.” The touch sensor (213) may provide hovering data about the time or location of hovering around the touch sensor (213) to the processor (120) when an external object is located within a first distance from the touch sensor (or in proximity, hovering above the touch sensor). The hovering data may be described as a “hovering mode / proximity mode.”

[0070] According to one embodiment, the wearable electronic device (200) may obtain hovering data using at least one of a touch sensor (213), a proximity sensor (not shown), or / and a depth sensor (217) to generate information about a distance, location, or time point between the touch sensor (213) and an external object.

[0071] According to one embodiment, the interior of the housing (210) may include components of FIG. 1, for example, a processor (e.g., processor (120) of FIG. 1) and memory (e.g., memory (130) of FIG. 1).

[0072] In one embodiment, the memory (130) may store various instructions that may be performed by the processor (120). The instructions may include arithmetic and logical operations, data movement, or control commands such as input / output that may be recognized by the processor (120). The memory (130) may include volatile memory (e.g., volatile memory (132) of FIG. 1) and non-volatile memory (e.g., non-volatile memory (134) of FIG. 1), and may temporarily or permanently store various data.

[0073] In one embodiment, the processor (120) may be operatively, functionally, and / or electrically connected to each component of the wearable electronic device (200) and may be configured to perform operations or data processing related to control and / or communication of each component. Operations performed by the processor (120) may be stored in the memory (130) and, when executed, may be executed by instructions that cause the processor (120) to operate.

[0074] Hereinafter, the computational and data processing functions that the processor (120) can implement on the wearable electronic device (200) are not limited, but a series of operations related to the XR content service function will be described. The operations of the processor (120) described below can be performed by executing instructions stored in the memory (130).

[0075] According to one embodiment, the processor (120) may generate a virtual object based on virtual information based on image information. The processor (120) may output a virtual object related to an XR service together with background space information through the display assembly (300). For example, the processor (120) may capture an image related to an actual space corresponding to the field of view of a user wearing the wearable electronic device (200) through the second function camera (211, 212) to obtain image information or generate a virtual space for a virtual environment. For example, the processor (120) may control the display assembly (300) to display XR content (hereinafter referred to as an XR content screen) in which at least one virtual object is output to be overlapped in an area determined to be a display area or a field of view (FoV) of the user.

[0076]

[0077] FIG. 3A is an assembled perspective view of a display assembly according to one embodiment. FIG. 3B is an exploded perspective view of a display assembly according to one embodiment. FIG. 3C is an exploded cross-sectional view of a display assembly according to one embodiment. FIG. 3D is an enlarged view of portion A of FIG. 3C. FIG. 3E is an exploded cross-sectional view of a cap assembly according to one embodiment.

[0078] Referring to FIGS. 3A to 3E, in one embodiment, the display assembly (300) may include a display module (400) and a cap assembly (500).

[0079] In one embodiment, a display module (400) may provide visual information to a user. The display module (400) may include a module housing (410), a display panel (420), a main barrel (430), and / or a lens assembly (440).

[0080] In one embodiment, the module housing (410) may provide a space in which each component of the display module (400) is placed. For example, the module housing (410) may provide a space in which the display panel (420), the main barrel (430), and / or the lens assembly (440) are placed.

[0081] In one embodiment, the display panel (420) can generate light (e.g., visible light) in at least a first direction (①). The display panel (420) can be disposed in the module housing (410). For example, the display panel (420) can be fixedly connected to a second direction (②) portion of the module housing (410). The light generated from the display panel (420) can pass through the lens assembly (440) and be transmitted to the user's eyes.

[0082] In one embodiment, the main barrel (430) may provide a space in which the lens assembly (440) is placed. For example, the main barrel (430) may include a space in which the lens assembly (440) is seated. The main barrel (430) may be formed to surround the outer periphery of the lens assembly (440). The main barrel (430) may be placed in the module housing (410). For example, the main barrel (430) may be fixedly connected to a first direction (①) portion of the module housing (410). Meanwhile, this is exemplary, and the main barrel (430) and the module housing (410) may be formed substantially integrally.

[0083] In one embodiment, the lens assembly (440) may be positioned inside the main barrel (430). The lens assembly (440) may be positioned in a first direction (①) with respect to the display panel (420). The lens assembly (440) may provide a path for light (e.g., visible light) to pass through. For example, the lens assembly (440) may be configured to provide a path for light generated from the display panel (420) to reach the user's eyes. For example, the lens assembly (440) may be configured to magnify and / or reduce content displayed on the display panel (420) and transmit the magnified and / or reduced content to the user's eyes.

[0084] In one embodiment, the lens assembly (440) may include at least one main lens (441) and / or at least one polarizing film (442). For example, the main lens (441) may include at least one of a Fresnel lens, a pancake lens, a convex lens, or a multi-channel lens. However, the type of the main lens (441) is not limited thereto. For example, the main lens (441) may include a first main lens (441a), a second main lens (441b), a third main lens (441c), and a fourth main lens (441d). For example, the first main lens (441a), the second main lens (441b), the third main lens (441c), and the fourth main lens (441d) may be sequentially arranged from the first direction (①) toward the second direction (②). For example, the first main lens (441a) may be positioned at the outermost side in the first direction (①) among the plurality of main lenses (441). For example, the polarizing film (442) may include a first polarizing film (442a) and a second polarizing film (442b). For example, the first polarizing film (442a) may be positioned on the surface of the first main lens (441a) in the first direction (①). For example, the first polarizing film (442a) may be attached to the surface of the first main lens (441a) in the first direction (①) and may be exposed to the outside of the display module (400). For example, the second polarizing film (442b) may be positioned between the first main lens (441a) and the second main lens (441b). However, this is an example, and the number, position and / or shape of the main lens (441) and / or polarizing film (442) are not limited thereto.

[0085] In one embodiment, the first main lens (441a) positioned at the outermost side in the first direction (①) among the plurality of main lenses (441) may have an outer region (443) cut to be inclined. For example, the first main lens (441a) may include a lens surface (4411) and a first inclined surface (4412). The lens surface (4411) may be a surface facing the first direction (①). The first inclined surface (4412) may be a surface formed to be inclined at the outer side of the lens surface (4411). For example, the first inclined surface (4412) may be formed to be inclined downward in a direction facing the outside of the lens assembly (440). A second inclined surface (431) may be formed on an inner region of the main barrel (430) that is in contact with the first main lens (441a). The second inclined surface (431) may be formed in an opposite direction to the first inclined surface (4412). For example, the second inclined surface (431) may be formed to slope downward in a direction toward the center of the main barrel (430). The first inclined surface (4412) and the second inclined surface (431) may be positioned adjacent to each other to form a space between them where the adhesive material (450) is applied.

[0086] In one embodiment, the first inclined surface (4412) may be inclined at an angle (T) of about 45 degrees or less with respect to the lens surface (4411). With this structure, even if light generated from the display panel (420) is reflected on the first inclined surface (4412) when passing through the outer region (443) of the first main lens (441a), the light may be reflected in a direction toward the outer edge of the lens assembly (440) rather than toward the center of the lens assembly (440). Therefore, a scattering phenomenon in which light generated from the display panel (420) is reflected on the first inclined surface (4412) and is reflected in a direction toward the center of the lens assembly (440) can be prevented or reduced.

[0087] In one embodiment, the adhesive member (450) may be applied between the first inclined surface (4412) and the second inclined surface (431) to adhere the first main lens (441a) and the main barrel (430) to each other. The adhesive member (450) may be configured to have a black color for light blocking. The black adhesive member (450) may block at least a portion of light leaking into the outer region (443) of the lens assembly (440). For example, the black adhesive member (450) may block at least a portion of light passing through the first inclined surface (4412) of the first main lens (441a). Meanwhile, when the adhesive member (450) does not have a black color, a surface treatment for light blocking may be applied to the first inclined surface (4412). For example, the surface treatment may include at least one of laser treatment, blasting, roughening with a curve, or printing. However, these are merely examples, and the types of surface treatment are not limited thereto, and various surface treatments may be applied for light blocking.

[0088] In one embodiment, light generated from the display panel (420) may leak out of the display module (400) without passing through the first polarizing film (442a) in the outer region (443) of the lens assembly (440) (e.g., at least a portion of the lens surface (4411) and / or at least a portion of the first inclined surface (4412). For example, if the adhesive member (450) is not sufficiently applied to the area where the adhesive member (450) is applied (e.g., the first inclined surface (4412)) located in the outer region (443) of the lens assembly (440), light may leak out of the outer region (443) of the lens assembly (440). For example, if a manufacturing tolerance occurs in the first polarizing film (442a) attached to the lens surface (4411) of the first main lens (441a), or if an alignment error occurs between the first polarizing film (442a) and the first main lens (441a), light may leak out to the outer region (443) of the lens assembly (440). However, this is merely exemplary, and light may leak out to the outer region (443) of the lens assembly (440) for various reasons.

[0089] In one embodiment, the cap assembly (500) may be configured to be detachably attached to the first direction (①) portion of the display module (400). For example, the cap assembly (500) may be replaceable. For example, a user may attach the cap assembly (500) to the display module (400) or remove it from the display module (400) as needed.

[0090] In one embodiment, the cap assembly (500) may include a cap barrel (510), a cap lens (520), a shading layer (530), an anti-slip layer (540), an adhesive layer (550), and / or a sealing member (560).

[0091] In one embodiment, the cap barrel (510) may provide a space in which each component of the cap assembly (500) (e.g., the cap lens (520), the light-blocking layer (530), the anti-scattering layer (540), the adhesive layer (550), and / or the sealing member (560)) is arranged. The cap barrel (510) may be configured to be detachably attached to a first direction (①) portion of the display module (400). For example, the cap barrel (510) may be configured to be detachably attached to a first direction (①) portion of the main barrel (430). For example, the cap barrel (510) may be configured to surround an end of the main barrel (430) in the first direction (①) from the outside. For example, the inner diameter of the cap barrel (510) may be substantially the same as the outer diameter of the main barrel (430). For example, the first direction (①) end of the main barrel (430) may be configured to be inserted into the inside of the cap barrel (510). A stopper (511) may be formed on the inside of the cap barrel (510) to adjust the depth to which the first direction (①) end of the main barrel (430) is inserted. The stopper (511) may be formed to protrude inward from the inner surface of the cap barrel (510).

[0092] In one embodiment, the cap lens (520) may be provided on the cap barrel (510). For example, the cap lens (520) may be positioned in the first direction (①) relative to the stopper (511) of the cap barrel (510). When the cap assembly (500) is coupled to the first direction (①) of the display module (400), the cap lens (520) may be positioned in the first direction (①) of the lens assembly (440) to supplement the enlargement and / or reduction function of the lens assembly (440). For example, the cap lens (520) may include a concave lens surface to increase the viewing angle of the lens assembly (440). For example, the cap lens (520) may include a convex lens surface to reduce the viewing angle of the lens assembly (440). The cap lens (520) may include a high refractive index material so as to have a relatively thin thickness while having a high refractive index. For example, the cap lens (520) may be configured to have a refractive index of 1.6 or greater. For example, the cap lens (520) may include a plastic and / or glass material. For example, the cap lens (520) may include a plastic material having a refractive index of 1.6 to 1.67. For example, the cap lens (520) may include a glass material having a refractive index of 1.8 to 2.0. However, this is merely exemplary, and the shape, refractive index, and / or material of the cap lens (520) are not limited thereto.

[0093] In one embodiment, a surface treatment for light blocking may be applied to the outer region (521) of the cap lens (520). For example, the surface treatment may include at least one of laser treatment, corrosion treatment, blasting, roughening with a curve, or printing treatment. However, this is merely an example, and the type of surface treatment is not limited thereto, and various surface treatments may be applied for light blocking. For example, the outer region (521) may refer to a region having a specified width from the outermost side toward the center of the cap lens (520). For example, the outer region (521) may be formed in a substantially circular shape. For example, the outer region (521) may include a first outer region (521a) formed on a surface of the cap lens (520) facing a first direction (①), and a second outer region (521b) formed on a surface of the cap lens (520) facing a second direction (②). When the wearable electronic device (e.g., the wearable electronic device (200) of FIG. 2B) is viewed from the first direction (①), at least a portion of the outer region (521) of the cap lens (520) to which the surface treatment is applied may overlap the outer region (443) of the lens assembly (440). For example, when the wearable electronic device (e.g., the wearable electronic device (200) of FIG. 2B) is viewed from the first direction (①), at least a portion of the outer region (521) of the cap lens (520) to which the surface treatment is applied may overlap the region between the outer periphery of the lens assembly (440) and the inner periphery of the main barrel (430).

[0094] In one embodiment, the shading layer (530) may be positioned on one side of the cap lens (520). For example, the shading layer (530) may be laminated on one side of the cap lens (520). For example, as illustrated in FIG. 3E, the shading layer (530) may be positioned on a side of the cap lens (520) facing the first direction (①). However, this is merely exemplary, and the shading layer (530) may be positioned on a side of the cap lens (520) facing the second direction (②). The shading layer (530) may be formed in a substantially circular shape with a cavity in the center. When the wearable electronic device (e.g., the wearable electronic device (200) of FIG. 2B) is viewed in the first direction (①), at least a portion of the shading layer (530) may overlap the outer region (443) of the lens assembly (440). For example, when a wearable electronic device (e.g., the wearable electronic device (200) of FIG. 2B) is viewed from the first direction (①), at least a portion of the light-shielding layer (530) may overlap an area between the outer periphery of the lens assembly (440) and the inner periphery of the main barrel (430). For example, a surface treatment for light-shielding may be applied to the light-shielding layer (530). For example, the surface treatment may include at least one of laser treatment, corrosion treatment, blasting, roughening with a curve, or printing treatment. However, this is merely an example, and the type of surface treatment is not limited thereto, and various surface treatments may be applied for light-shielding. For example, the shading layer (530) may include a polarizing member positioned so that its polarization direction is different from that of the polarizing film (442) of the lens assembly (440) (e.g., the first polarizing film (442a) positioned at the outermost side in the first direction (①) among the polarizing films (442) of the lens assembly (440). For example, the shading layer (530) may be positioned so that its polarization direction is substantially different from that of the first polarizing film (442a) by 90.If the shading layer (530) includes a polarizing member of the same material as the polarizing film (442) of the lens assembly (440), it can have the same texture, thereby reducing the sense of incongruity in design.

[0095] In one embodiment, at least a portion of the light leaking through the outer region (443) of the lens assembly (440) may be blocked by the cap assembly (500) coupled to the first direction (①) portion of the display module (400). For example, at least a portion of the light leaking through the outer region (443) of the lens assembly (440) may be blocked by the outer region (521) of the cap lens (520) and / or the light-shielding layer (530). Therefore, in the display assembly (300) according to one embodiment, at least a portion of the light leaking through the outer region (443) of the lens assembly (440) may be blocked by using the cap assembly (500), thereby blocking or reducing the scattering phenomenon caused by the leaking light. Meanwhile, in one embodiment, a surface treatment may be applied to the outer region (521) of the cap lens (520), and a separate light-shielding layer (530) may not be provided. In one embodiment, only a separate shading layer (530) may be provided, and no surface treatment may be applied to the outer region (521) of the cap lens (520). The expression "light is blocked" in this document should not be understood to mean that light is completely blocked, but should also be understood to include a reduction in the amount of light.

[0096] In one embodiment, the anti-scattering layer (540) may be positioned in the first direction (①) with respect to the cap lens (520). For example, the anti-scattering layer (540) may be positioned on the first direction (①) side of the cap lens (520) and / or the first direction (①) side of the light-shielding layer (530). The anti-scattering layer (540) may protect the cap lens (520) by preventing the first direction (①) side of the cap lens (520) from being directly exposed to the outside of the cap assembly (500). The anti-scattering layer (540) may prevent or reduce fragments from scattering when the cap lens (520) and / or the lens assembly (440) are damaged. In one embodiment, a surface treatment for light blocking may be applied to an outer region of the anti-scattering layer (540) (e.g., an area overlapping the outer region (443) of the lens assembly (440) when looking at the wearable electronic device (200) from the first direction (①). For example, the surface treatment may include at least one of laser treatment, corrosion treatment, blasting, roughening with a curve, or printing treatment.
