[0043] Some aspects of this disclosure and methods of implementing it can be more readily understood by referring to the detailed description and accompanying drawings of the embodiments. Hereinafter, embodiments will be described in more detail with reference to the accompanying drawings. However, the described embodiments may be implemented in a variety of different forms and should not be construed as limited to the embodiments shown herein. Rather, these embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey aspects of this disclosure to those skilled in the art. Therefore, processes, elements, and techniques not essential for a full understanding of aspects of this disclosure by those skilled in the art may not be described.

[0044] Unless otherwise stated, the same reference numerals, characters, or combinations thereof denote the same elements throughout the drawings and written description, and therefore their description will not be repeated. Furthermore, portions unrelated to the description of some embodiments may not be shown for clarity.

[0045] In the accompanying drawings, the relative dimensions of elements, layers, and regions may be exaggerated for clarity. Furthermore, crosshairs and / or shading are typically used in the drawings to clarify the boundaries between adjacent elements. Therefore, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for particular materials, material properties, dimensions, scale, commonalities between illustrated elements, and / or any other characteristics, properties, or characteristics of the elements.

[0046] Various embodiments are described herein with reference to cross-sectional views as schematic diagrams of implementations and / or intermediate structures. Similarly, variations in the shapes shown in the figures should be anticipated, for example, due to manufacturing techniques and / or tolerances. Furthermore, the specific structural or functional descriptions disclosed herein are merely illustrative for the purpose of describing embodiments according to the concept of this disclosure. Therefore, the embodiments disclosed herein should not be construed as limited to the shapes of the specifically shown areas, but should include, for example, deviations in shape due to manufacturing processes.

[0047] For example, an implantation region shown as rectangular will typically have rounded or curved features at its edges and / or a gradient of implantation concentration, rather than a binary change from an implantation region to a non-implantation region. Similarly, the implantation region formed by implantation may result in some implantation in the area between the implantation region and the surface through which the implantation occurs. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to represent the actual shape of the areas of the device, nor are they intended to be limiting. Furthermore, as those skilled in the art will recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of this disclosure.

[0048] In the detailed description, numerous specific details are set forth for illustrative purposes to provide a thorough understanding of the various embodiments. However, it will be apparent that various embodiments may be implemented without these specific details or with one or more equivalent arrangements. In other instances, well-known structures and devices are shown in block diagram form to avoid unnecessarily obscuring the various embodiments.

[0049] For ease of explanation, spatial relative terms such as “below,” “under,” “lower,” “below,” “above,” “upper,” etc., may be used herein to describe the relationship between one element or feature and another element (or feature) or feature (or feature) as shown in the figures. It should be understood that, in addition to the orientations depicted in the figures, spatial relative terms are intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “below,” “under,” or “below” other elements or features will consequently be oriented “above” other elements or features. Thus, the exemplary terms “below” and “below” can encompass both above and below orientations. The device may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative descriptive terms used herein should be interpreted accordingly. Similarly, when a first part is described as being arranged “on” a second part, this means that the first part is arranged above or below the second part, not limited to its upper side based on the direction of gravity.

[0050] Furthermore, in this specification, the phrase "in a plane" or "plan view" refers to viewing the target portion from the top, and the phrase "in a cross-section" refers to viewing the cross-section formed by vertically cutting the target portion from the side.

[0051] It will be understood that when a component, layer, region, or part is referred to as being "formed" on, "connected to," or "joined to" another component, layer, region, or part, it can be directly formed on, directly on, directly connected to, or directly joined to that component, layer, region, or part, or indirectly formed on, indirectly on, indirectly connected to, or indirectly joined to that component, layer, region, or part, such that one or more intermediate components, layers, regions, or parts may exist. For example, when a layer, region, or part is referred to as being "electrically connected" or "electrically joined" to another layer, region, or part, it can be directly electrically connected or directly electrically joined to the other layer, region, and / or part, or an intermediate layer, region, or part may exist. However, "directly connected / directly joined" means that one part is directly connected / joined to another part without any intermediate parts. Similarly, other expressions describing relationships between components, such as “between” and “directly between” or “adjacent to” and “directly adjacent to”, can be interpreted in a similar way. Furthermore, it will be understood that when an element or layer is referred to as being “between” two elements or layers, it can be the only element or layer between the two elements or layers, or there may be one or more elements or layers in between.

[0052] For the purposes of this disclosure, when following a list of elements, expressions such as “at least one of…” modify the elements of the entire list rather than individual elements within that list. For example, “at least one of X, Y, and Z,” “at least one of X, Y, or Z,” and “at least one selected from a group consisting of X, Y, and Z” can be interpreted as only X, only Y, only Z, any combination of two or more of X, Y, and Z (such as, for example, XYZ, XYY, YZ, and ZZ), or any variation thereof. Similarly, expressions such as “at least one of A and B” can include A, B, or A and B. As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items. For example, expressions such as “A and / or B” can include A, B, or A and B.

[0053] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or part from another element, component, region, layer, or part. Therefore, without departing from the spirit and scope of this disclosure, the first element, first component, first region, first layer, or first part described below may be referred to as a second element, second component, second region, second layer, or second part.

[0054] In this example, the X-axis, Y-axis, and / or Z-axis are not limited to the three axes of a Cartesian coordinate system and can be interpreted in a broader sense. For example, the X-axis, Y-axis, and Z-axis can be perpendicular to each other, or they can represent different directions that are not perpendicular to each other. The same applies to the first direction, the second direction, and / or the third direction.

[0055] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “an” are intended to also include the plural forms. It will be further understood that, when used in this specification, the terms “comprises,” “comprising,” “have,” “having,” “includes,” and “including” indicate the presence of the described features, integrals, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0056] As used herein, the terms “substantially,” “about,” “approximately,” and similar terms are used as approximate terms rather than as terms of degree and are intended to account for inherent biases in measured or calculated values ​​that would be recognized by one of ordinary skill in the art. As used herein, “about” or “approximately” includes the value as well as the average of the values ​​within an acceptable range of deviations from the particular value, as determined by one of ordinary skill in the art, taking into account the measurement in question and errors associated with the measurement of the particular quantity (i.e., limitations of the measurement system). For example, “about” may mean within one or more standard deviations, or within ±30%, ±20%, ±10%, ±5% of the value. Additionally, the use of “may” in describing embodiments of this disclosure indicates “one or more embodiments of this disclosure.”

[0057] When one or more implementations can be carried out differently, the specific process sequence can be performed differently than the described sequence. For example, two consecutively described processes can be performed substantially simultaneously or in the reverse order of their description.

[0058] Furthermore, any numerical range disclosed and / or described herein is intended to include all subranges with the same numerical precision contained within the described range. For example, the range “1.0 to 10.0” is intended to include all subranges between the described minimum value of 1.0 and the described maximum value of 10.0 (inclusive), that is, a minimum value equal to or greater than 1.0 and a maximum value equal to or less than 10.0, such as, for example, 2.4 to 7.6. Any maximum numerical limit described herein is intended to include all lower numerical limits contained therein, and any minimum numerical limit described herein is intended to include all higher numerical limits contained therein. Therefore, the applicant reserves the right to modify this specification, including the claims, to clearly describe any subranges contained within the range expressly described herein. All such ranges are intended to be described inherently in this specification such that modifications to expressly describe any such subranges will be required.

[0059] The electronic or electrical devices and / or any other related devices or components according to embodiments of this disclosure described herein can be implemented using any suitable hardware, firmware (e.g., application-specific integrated circuits), software, or a combination of software, firmware, and hardware. For example, various components of these devices may be formed on a single integrated circuit (IC) chip or on separate IC chips. Alternatively, various components of these devices may be implemented on a flexible printed circuit film, tape-on-a-carrier package (TCP), printed circuit board (PCB), or formed on a substrate.

[0060] Furthermore, the various components of these devices can be processes or threads that run on one or more processors in one or more computing devices, execute computer program instructions, and interact with other system components for performing the various functions described herein. The computer program instructions are stored in memory implemented in the computing device using standard storage devices, such as, for example, random access memory (RAM). The computer program instructions may also be stored in other non-transitory computer-readable media, such as, for example, CD-ROMs, flash drives, etc. Additionally, those skilled in the art will recognize that, without departing from the spirit and scope of some embodiments of this disclosure, the functions of various computing devices may be combined or integrated into a single computing device, or the functions of a particular computing device may be distributed across one or more other computing devices.

[0061] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It should also be understood that, unless expressly defined herein, terms, such as those defined in common dictionaries, shall be interpreted as having the same meaning as they have in the relevant field and / or the context of this specification, and shall not be interpreted in an idealized or overly formal sense.

[0063] In the following description, the first direction X, the second direction Y, and the third direction Z are different directions and intersect each other. For example, the first direction X can be the vertical direction, the second direction Y can be the width direction, and the third direction Z can be the thickness direction. The third direction Z may include the side where the user's eyeball is located and the side displaying the images of the first display device DP1 and the second display device DP2, which will be described in more detail later. It should be noted that the directions and names are relative and are not limited to those directions and names described above.

[0064] In the following description, optical device 1 may include a head-mounted optical device mounted on (or configured to be mounted on) a user’s head to provide a screen on which images or videos are displayed to the user.

[0065] Head-mounted optical devices can include see-through head-mounted optical devices that provide augmented reality based on actual external objects, and closed (or non-see-through) head-mounted optical devices that provide virtual reality to a user using a screen independent of external objects. In the following description, closed head-mounted optical devices will be described as examples. It should be understood that embodiments according to this disclosure are not limited thereto.

[0066] Reference Figure 1 and Figure 2 The optical device 1 may include a main frame MF, a first display device DP1, a second display device DP2, a first multi-channel lens LS1 and a second multi-channel lens LS2, a first camera mounting component (or a first camera mounting part, or a first camera mounting structure) CS1, a second camera mounting component (or a second camera mounting part, or a second camera mounting structure) CS2, a first camera CMR1 and a second camera CMR2.

[0067] The main frame MF can be worn on the user's face. The main frame MF can have a shape that conforms to the shape of the user's head (face). According to some embodiments of this disclosure, the main frame MF can have a shape similar to glasses, but embodiments of this disclosure are not limited thereto.

[0068] The first display device DP1, the second display device DP2, the first multi-channel lens LS1, the second multi-channel lens LS2, the first camera mounting component CS1, the second camera mounting component CS2, the first camera CMR1, and the second camera CMR2 can be mounted on the main frame MF. According to some embodiments, the main frame MF may also include structures such as straps and strips for easy mounting. According to some embodiments, the controller, image processor, and lens receiver may also be mounted on the main frame MF.

[0069] First display device DP1 and second display device DP2 display images and / or videos. Light used for displaying images and / or videos can be output from first display device DP1 and second display device DP2.

[0070] The first display device DP1 and the second display device DP2 can be fixed to the main frame MF or can be detachably connected to the main frame MF. The first display device DP1 and the second display device DP2 can be opaque, transparent, or translucent, depending on the design of the optical device 1, for example, the type of optical device 1. The first display device DP1 and the second display device DP2 can include, but are not limited to, optical devices including electronic components, such as display modules including display panels described later, or mobile terminals including display panels.

[0071] Each of the first display device DP1 and the second display device DP2 may include a display panel for displaying images or videos.

[0072] The display panel can be a light-emitting display panel that includes light-emitting elements. For example, the display panel can include, but is not limited to, an organic light-emitting display panel that uses organic light-emitting diodes that include organic emission layers, a micro light-emitting diode display panel that uses micro LEDs, a quantum dot light-emitting display panel that includes quantum dot light-emitting diodes that include quantum dot emission layers, or an inorganic light-emitting display panel that uses inorganic light-emitting elements that include inorganic semiconductors.

[0073] According to some embodiments of this disclosure, the optical device 1 may include, but is not limited to, two display devices spaced apart from each other, such that they respectively correspond to the user's eye. According to some embodiments, the first display device DP1 and the second display device DP2 may be replaced by a first multi-channel lens LS1, a second multi-channel lens LS2, and a display device arranged to overlap with the first multi-channel lens LS1 and the second multi-channel lens LS2.

[0074] The first multi-channel lens LS1 and the second multi-channel lens LS2 can respectively transmit light output from the first display device DP1 and the second display device DP2 to provide them to the user.

[0075] The first multi-channel lens LS1 and the second multi-channel lens LS2 can reflect and / or refract light emitted from the first display device DP1 and the second display device DP2 to provide them to the user. The first multi-channel lens LS1 and the second multi-channel lens LS2 can provide multiple channels through which light emitted from the first display device DP1 and the second display device DP2 passes. Multiple channels allow light emitted from the first display device DP1 and the second display device DP2 to travel different paths to provide them to the user. Light emitted from the first display device DP1 and the second display device DP2 can be incident on corresponding channels, allowing the magnified image to be focused on the user's eye. The multiple channels can be provided by multiple sub-lenses LS11, LS12, LS13, LS14, LS21, LS22, LS23, and LS24 (see [link to documentation]). Figure 3 This will be achieved through [method / method], which will be described in more detail later.

[0076] A first multi-channel lens LS1 may be located on a first display device DP1, and a second multi-channel lens LS2 may be located on a second display device DP2. The first multi-channel lens LS1 and the second multi-channel lens LS2 may be located at positions corresponding to the user's left and right eyes, respectively. The first multi-channel lens LS1 may be arranged to cover the first camera CMR1 and the first camera mounting member CS1. The second multi-channel lens LS2 may be arranged to cover the second camera CMR2 and the second camera mounting member CS2. (See later...) Figures 3 to 8 The first multi-channel lens LS1 and the second multi-channel lens LS2 are described in detail.

[0077] The first camera mounting component CS1 and the second camera mounting component CS2 can be located on the first display device DP1 and the second display device DP2, respectively. The first camera mounting component CS1 can be located between the first display device DP1 and the first multi-channel lens LS1, and the second camera mounting component CS2 can be located between the second display device DP2 and the second multi-channel lens LS2. The first camera CMR1 can be mounted on the first camera mounting component CS1, and the second camera CMR2 can be mounted on the second camera mounting component CS2. Since the first camera CMR1 and the second camera CMR2 overlap with the first multi-channel lens LS1 and the second multi-channel lens LS2 through the first camera mounting component CS1 and the second camera mounting component CS2, respectively, the internal space of the optical device 1 can be effectively utilized, and the overall volume of the optical device 1 can be reduced.

[0078] The first camera CMR1 and the second camera CMR2 can be located on the first camera mounting member CS1 and the second camera mounting member CS2, respectively. The first camera CMR1 can be located between the first camera mounting member CS1 and the first multi-channel lens LS1, and the second camera CMR2 can be located between the second camera mounting member CS2 and the second multi-channel lens LS2.

[0079] The first display device DP1, the first camera mounting component CS1, the first camera CMR1, and the first multi-channel lens LS1 can be arranged to overlap each other in the third direction Z. The second display device DP2, the second camera mounting component CS2, the second camera CMR2, and the second multi-channel lens LS2 can be arranged to overlap each other in the third direction Z. The third direction Z can refer to the direction of the user's eyeball.

[0080] The first camera CMR1 and the second camera CMR2 can capture images for detecting the position of a user's pupil. The first camera CMR1 and the second camera CMR2 include various types of cameras (such as infrared cameras and visible light cameras) or photoelectric conversion elements (such as image sensors that detect light and generate electrical charge) capable of detecting light reflected from the user's pupil. According to some embodiments of this disclosure, the first camera CMR1 and the second camera CMR2 may include, but are not limited to, infrared cameras.

[0081] According to some embodiments of this disclosure, each of the first camera CMR1 and the second camera CMR2 may further include a light source that emits light for detecting the position of a user's pupil. The light may include visible light or infrared light. According to some embodiments of this disclosure, the light source may be integrally mounted with each of the first camera CMR1 and the second camera CMR2, but embodiments of this disclosure are not limited thereto.

[0082] According to some embodiments, the light source can be mounted separately from the first camera CMR1 and the second camera CMR2 on the optical device 1. According to some embodiments, the light source can be located near the first camera CMR1 or the second camera CMR2 on the first camera bracket CS1_CP or the second camera bracket CS2_CP, which will be described later. It should be understood that the embodiments according to this disclosure are not limited thereto.

[0083] According to some embodiments, the optical device 1 may also include a controller for controlling the overall operation of the optical device 1.

[0084] The controller can control the operation of the first camera CMR1, the second camera CMR2, and the light source. The controller can calculate the position of the user's pupils by analyzing the images captured by the first camera CMR1 and the second camera CMR2. Based on the calculated position of the user's pupils, the controller can control the first display device DP1 and the second display device DP2 to display the corresponding images. For example, the controller can be implemented as a dedicated processor including an embedded processor and / or a general-purpose processor including a central processing unit or application processor. It should be understood that embodiments according to this disclosure are not limited thereto.

[0086] Reference Figures 1 to 3 The first multi-channel lens LS1 and the second multi-channel lens LS2 can be located at positions corresponding to the user's eye. For example, the first multi-channel lens LS1 and the second multi-channel lens LS2 can be arranged symmetrically with respect to an imaginary axis in the second direction Y. The first multi-channel lens LS1 and the second multi-channel lens LS2 can have substantially the same or similar shapes and structures. The first multi-channel lens LS1 and the second multi-channel lens LS2 can have a generally circular shape when viewed from above (e.g., in a plan view), but the shapes of the first multi-channel lens LS1 and the second multi-channel lens LS2 are not limited to this.

[0087] The first multi-channel lens LS1 may include multiple sub-lenses LS11, LS12, LS13, and LS14, and the second multi-channel lens LS2 may include multiple sub-lenses LS21, LS22, LS23, and LS24. The multiple sub-lenses LS11, LS12, LS13, LS14, LS21, LS22, LS23, and LS24 may each provide multiple channels through which light output from the first display device DP1 and the second display device DP2 passes.

[0088] According to some embodiments of this disclosure, the first multi-channel lens LS1 may include four sub-lenses LS11, LS12, LS13, and LS14, and the second multi-channel lens LS2 may include four sub-lenses LS21, LS22, LS23, and LS24; however, the number of sub-lenses forming a single multi-channel lens is not limited to four. According to some embodiments of this disclosure, the first multi-channel lens LS1 and the second multi-channel lens LS2 may include three or fewer sub-lenses or five or more sub-lenses.

[0089] In the following description, for ease of explanation, the sub-lens LS11 located at the upper right end relative to the center of the first multi-channel lens LS1 is referred to as the first sub-lens LS11, the sub-lens LS12 located at the lower right end is referred to as the second sub-lens LS12, the sub-lens LS13 located at the lower left end is referred to as the third sub-lens LS13, and the sub-lens LS14 located at the upper left end is referred to as the fourth sub-lens LS14. Furthermore, with respect to the center of the second multi-channel lens LS2, the sub-lens LS21 located at the upper right end is referred to as the fifth sub-lens LS21, the sub-lens LS22 located at the lower right end is referred to as the sixth sub-lens LS22, the sub-lens LS23 located at the lower left end is referred to as the seventh sub-lens LS23, and the sub-lens LS24 located at the upper left end is referred to as the eighth sub-lens LS24.

[0090] Reference Figures 1 to 4 The multiple sub-lenses LS11, LS12, LS13, and LS14 of the first multi-channel lens LS1 can be centrally symmetrical with respect to the first multi-channel lens LS1. Similarly, the multiple sub-lenses LS21, LS22, LS23, and LS24 of the second multi-channel lens LS2 can be centrally symmetrical with respect to the second multi-channel lens LS2. For example, the first sub-lens LS11, the second sub-lens LS12, the third sub-lens LS13, and the fourth sub-lens LS14 can have a shape that is centrally symmetrical with respect to the first multi-channel lens LS1. The fifth sub-lens LS21, the sixth sub-lens LS22, the seventh sub-lens LS23, and the eighth sub-lens LS24 can also have a shape that is centrally symmetrical with respect to the second multi-channel lens LS2.

[0091] The plurality of sub-lenses LS11, LS12, LS13, and LS14 of the first multi-channel lens LS1 can be integrally connected to each other. Similarly, the plurality of sub-lenses LS21, LS22, LS23, and LS24 of the second multi-channel lens LS2 can be integrally connected to each other. For example, the first sub-lens LS11, the second sub-lens LS12, the third sub-lens LS13, and the fourth sub-lens LS14 can be processed such that they are integrally connected to each other to form a single first multi-channel lens LS1. The fifth sub-lens LS21, the sixth sub-lens LS22, the seventh sub-lens LS23, and the eighth sub-lens LS24 can be processed such that they are integrally connected to each other to form a single second multi-channel lens LS2. In other words, a single sub-lens can refer to a specific portion or region of the first multi-channel lens LS1 or the second multi-channel lens LS2 that provides a single channel. It should be understood that embodiments according to this disclosure are not limited thereto. According to some embodiments of this disclosure, the first multi-channel lens LS1 can be a lens assembly comprising a plurality of sub-lenses LS11, LS12, LS13, and LS14 spaced apart from each other. The second multi-channel lens LS2 can be a lens assembly comprising multiple sub-lenses LS21, LS22, LS23 and LS24 spaced apart from each other.

[0092] Each of the multiple sub-lenses LS11, LS12, LS13, LS14, LS21, LS22, LS23 and LS24 may include at least one outer surface facing the user's eyeball (i.e., facing the position of the user's eye when worn by the user).

[0093] For example, the first sub-lens LS11 may include a first outer surface LS11_NS and a second outer surface LS11_CS; the second sub-lens LS12 may include a third outer surface LS12_NS and a fourth outer surface LS12_CS; the third sub-lens LS13 may include a fifth outer surface LS13_NS and a sixth outer surface LS13_CS; and the fourth sub-lens LS14 may include a seventh outer surface LS14_NS and an eighth outer surface LS14_CS. The fifth sub-lens LS21 may include a ninth outer surface LS21_NS and a tenth outer surface LS21_CS; the sixth sub-lens LS22 may include an eleventh outer surface LS22_NS and a twelfth outer surface LS22_CS; the seventh sub-lens LS23 may include a thirteenth outer surface LS23_NS and a fourteenth outer surface LS23_CS; and the eighth sub-lens LS24 may include a fifteenth outer surface LS24_NS and a sixteenth outer surface LS24_CS.

[0094] As described above, the second multi-channel lens LS2 can be substantially the same as the first multi-channel lens LS1. According to some embodiments of this disclosure, the first outer surface LS11_NS, the second outer surface LS11_CS, the third outer surface LS12_NS, the fourth outer surface LS12_CS, the fifth outer surface LS13_NS, the sixth outer surface LS13_CS, the seventh outer surface LS14_NS, and the eighth outer surface LS14_CS can be substantially the same as the ninth outer surface LS21_NS, the tenth outer surface LS21_CS, the eleventh outer surface LS22_NS, the twelfth outer surface LS22_CS, the thirteenth outer surface LS23_NS, the fourteenth outer surface LS23_CS, the fifteenth outer surface LS24_NS, and the sixteenth outer surface LS24_CS, respectively. The following text will primarily describe the first outer surface LS11_NS, the second outer surface LS11_CS, the third outer surface LS12_NS, the fourth outer surface LS12_CS, the fifth outer surface LS13_NS, the sixth outer surface LS13_CS, the seventh outer surface LS14_NS, and the eighth outer surface LS14_CS.

[0095] The first outer surface LS11_NS, the third outer surface LS12_NS, the fifth outer surface LS13_NS, and the seventh outer surface LS14_NS can extend from the edge of the first multi-channel lens LS1 towards the center of the first sub-lens LS11. The first outer surface LS11_NS, the third outer surface LS12_NS, the fifth outer surface LS13_NS, and the seventh outer surface LS14_NS can extend such that they are tilted Z relative to a third party. The first outer surface LS11_NS, the third outer surface LS12_NS, the fifth outer surface LS13_NS, and the seventh outer surface LS14_NS can extend such that the width of the first multi-channel lens LS1 in the first direction X or the second direction Y is narrowed. According to some embodiments of this disclosure, each of the first outer surface LS11_NS, the third outer surface LS12_NS, the fifth outer surface LS13_NS, and the seventh outer surface LS14_NS can be, but is not limited to, a flat, tilted surface. According to some implementations, each of the first outer surface LS11_NS, the third outer surface LS12_NS, the fifth outer surface LS13_NS, and the seventh outer surface LS14_NS may include a curved surface.

[0096] The second outer surface LS11_CS, the fourth outer surface LS12_CS, the sixth outer surface LS13_CS, and the eighth outer surface LS14_CS can extend from the first outer surface LS11_NS, the third outer surface LS12_NS, the fifth outer surface LS13_NS, and the seventh outer surface LS14_NS toward the center of the first multi-channel lens LS1, respectively. When viewed from the top (or in a plan view), the second outer surface LS11_CS, the fourth outer surface LS12_CS, the sixth outer surface LS13_CS, and the eighth outer surface LS14_CS can be arranged around the center of the first multi-channel lens LS1. The second outer surface LS11_CS, the fourth outer surface LS12_CS, the sixth outer surface LS13_CS, and the eighth outer surface LS14_CS can be arranged such that they are connected to each other in a clockwise direction relative to the center of the first multi-channel lens LS1.

[0097] The second outer surface LS11_CS, the fourth outer surface LS12_CS, the sixth outer surface LS13_CS, and the eighth outer surface LS14_CS can be arranged such that they are inclined Z-axis relative to a third surface. The second outer surface LS11_CS, the fourth outer surface LS12_CS, the sixth outer surface LS13_CS, and the eighth outer surface LS14_CS can be arranged such that they are inclined relative to the first outer surface LS11_NS, the third outer surface LS12_NS, the fifth outer surface LS13_NS, and the seventh outer surface LS14_NS, respectively. For example... Figure 4 As shown, the edges connecting the first outer surface LS11_NS and the second outer surface LS11_CS, the edges connecting the third outer surface LS12_NS and the fourth outer surface LS12_CS, the edges connecting the fifth outer surface LS13_NS and the sixth outer surface LS13_CS, and the edges connecting the seventh outer surface LS14_NS and the eighth outer surface LS14_CS may protrude in a third-party Z-direction or outward direction. It should be understood that embodiments according to this disclosure are not limited thereto.

[0098] The second outer surface LS11_CS, the fourth outer surface LS12_CS, the sixth outer surface LS13_CS, and the eighth outer surface LS14_CS can be arranged such that they face a third direction Z. Each of the second outer surface LS11_CS, the fourth outer surface LS12_CS, the sixth outer surface LS13_CS, and the eighth outer surface LS14_CS can be referred to as an eye-side surface or a front surface facing the user's eye. The first outer surface LS11_NS, the third outer surface LS12_NS, the fifth outer surface LS13_NS, and the seventh outer surface LS14_NS can be connected to the second outer surface LS11_CS, the fourth outer surface LS12_CS, the sixth outer surface LS13_CS, and the eighth outer surface LS14_CS, respectively, and can be referred to as a surface that does not face the user's eyeball.

[0099] According to some embodiments of this disclosure, each of the second outer surface LS11_CS, the fourth outer surface LS12_CS, the sixth outer surface LS13_CS, and the eighth outer surface LS14_CS may be a convex surface projecting in the third direction Z. It should be understood that embodiments according to this disclosure are not limited thereto. According to some embodiments, each of the second outer surface LS11_CS, the fourth outer surface LS12_CS, the sixth outer surface LS13_CS, and the eighth outer surface LS14_CS may include a flat surface.

[0100] At least one lens boundary can be defined between the plurality of sub-lenses LS11, LS12, LS13, and LS14 of the first multi-channel lens LS1 and between the plurality of sub-lenses LS21, LS22, LS23, and LS24 of the second multi-channel lens LS2. For example, when the first multi-channel lens LS1 and the second multi-channel lens LS2 each have four sub-lenses (four channels), a cross-shaped lens boundary can be defined in each of the first multi-channel lens LS1 and the second multi-channel lens LS2 when viewed from top (or in a plan view). However, it should be understood that embodiments according to this disclosure are not limited thereto. The shape of the lens boundary can be varied depending on the design of the optical device 1.

[0101] Reference Figure 3 and Figure 4 The lens boundaries of the first multi-channel lens LS1 may include a first lens boundary BD1, a second lens boundary BD2, a third lens boundary BD3, and a fourth lens boundary BD4. The lens boundaries of the second multi-channel lens LS2 may include a fifth lens boundary BD5, a sixth lens boundary BD6, a seventh lens boundary BD7, and an eighth lens boundary BD8.

[0102] For the first multi-channel lens LS1, a first lens boundary BD1 can be defined between the second outer surface LS11_CS and the fourth outer surface LS12_CS; a second lens boundary BD2 can be defined between the fourth outer surface LS12_CS and the sixth outer surface LS13_CS; a third lens boundary BD3 can be defined between the sixth outer surface LS13_CS and the eighth outer surface LS14_CS; and a fourth lens boundary BD4 can be defined between the eighth outer surface LS14_CS and the second outer surface LS11_CS. For example... Figure 4 As shown, the first lens boundary BD1, the second lens boundary BD2, the third lens boundary BD3, and the fourth lens boundary BD4 can be, but are not limited to, the recesses between the second outer surface LS11_CS, the fourth outer surface LS12_CS, the sixth outer surface LS13_CS, and the eighth outer surface LS14_CS. According to some embodiments of this disclosure, when the first outer surface LS11_NS, the third outer surface LS12_NS, the fifth outer surface LS13_NS, and the seventh outer surface LS14_NS are connected to each other, the lens boundary can further include the boundary between the first outer surface LS11_NS, the third outer surface LS12_NS, the fifth outer surface LS13_NS, and the seventh outer surface LS14_NS.

[0103] Similarly, for the second multi-channel lens LS2, a fifth lens boundary BD5 can be defined between the tenth outer surface LS21_CS and the twelfth outer surface LS22_CS, a sixth lens boundary BD6 can be defined between the twelfth outer surface LS22_CS and the fourteenth outer surface LS23_CS, a seventh lens boundary BD7 can be defined between the fourteenth outer surface LS23_CS and the sixteenth outer surface LS24_CS, and an eighth lens boundary BD8 can be defined between the sixteenth outer surface LS24_CS and the tenth outer surface LS21_CS. The fifth lens boundary BD5, the sixth lens boundary BD6, the seventh lens boundary BD7, and the eighth lens boundary BD8 can be substantially the same as the first lens boundary BD1, the second lens boundary BD2, the third lens boundary BD3, and the fourth lens boundary BD4.

[0104] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The first camera mounting component CS1 may include a support ring CS1_SP, multiple feet CS1_LP1, CS1_LP2, CS1_LP3 and CS1_LP4, and a camera bracket CS1_CP.

[0105] According to some embodiments of this disclosure, the support ring CS1_SP, the plurality of legs CS1_LP1, CS1_LP2, CS1_LP3 and CS1_LP4, and the camera bracket CS1_CP can be integrally formed. That is, the support ring CS1_SP, the plurality of legs CS1_LP1, CS1_LP2, CS1_LP3 and CS1_LP4, and the camera bracket CS1_CP can represent a specific portion or a specific area of ​​the first camera mounting member CS1. It should be understood that embodiments according to this disclosure are not limited thereto. The support ring CS1_SP, the plurality of legs CS1_LP1, CS1_LP2, CS1_LP3 and CS1_LP4, and the camera bracket CS1_CP can be implemented as separate components.

[0106] The support ring CS1_SP can be connected to and support multiple legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4. According to some embodiments of this disclosure, the support ring CS1_SP can be implemented as an annular member conforming to the edge shape of the first multi-channel lens LS1, and the edge of the first multi-channel lens LS1 can be mounted on and supported by the support ring CS1_SP. It should be understood that the embodiments according to this disclosure are not limited thereto. The support ring CS1_SP can have various shapes, such as rectangular, square, and elliptical, for supporting the multiple legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 and the first multi-channel lens LS1. According to some embodiments, the support ring CS1_SP can be replaced by multiple members respectively arranged in the multiple legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 to support them.

[0107] Multiple legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 may be located inside the support ring CS1_SP. One side of each of the multiple legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 may be connected to the support ring CS1_SP, and the other side of each of the multiple legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 may be connected to the camera bracket CS1_CP. The multiple legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 may extend such that they are tilted relative to a third direction (Z). The other side of each of the multiple legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4, and the camera bracket CS1_CP connected to that other side, may protrude beyond the support ring CS1_SP in the third direction (Z).

[0108] The camera mount CS1_CP can be located inside the support ring CS1_SP to support the first camera CMR1. The camera mount CS1_CP can be arranged to overlap the center of the first multi-channel lens LS1. The camera mount CS1_CP can be supported by multiple legs CS1_LP1, CS1_LP2, CS1_LP3 and CS1_LP4.

[0109] Further reference Figure 6 When viewed from above (or in a plan view), the support ring CS1_SP, the multiple legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4, and the camera bracket CS1_CP can overlap with the edge portions of the multiple sub-lenses LS11, LS12, LS13, LS14, LS21, LS22, LS23, and LS24, making them invisible to the user and allowing most of the light transmitted through the sub-lenses LS11, LS12, LS13, LS14, LS21, LS22, LS23, and LS24 to pass through them. Light passing through the central portions of the multiple sub-lenses LS11, LS12, LS13, LS14, LS21, LS22, LS23, and LS24 can be incident on the user's pupil, while light passing through the edge portions of the multiple sub-lenses LS11, LS12, LS13, LS14, LS21, LS22, LS23, and LS24 can be blocked or refracted, preventing them from incident on the user's pupil.

[0110] Multiple supports CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 can be arranged to overlap with multiple lens boundaries in the third direction Z. Due to refraction through multiple sub-lenses LS11, LS12, LS13, LS14, LS21, LS22, LS23, and LS24, light passing through the multiple lens boundaries hardly reaches the user's eye, and therefore the multiple supports CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 are not visible to the user. Multiple lens boundaries can refer to specific portions or parallel regions adjacent to the edges of the individual sub-lenses, where light passing through is not visible to the user due to refraction by the multi-channel lenses.

[0111] Light emitted from the first display device DP1 can pass between multiple legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 of the first camera mounting component CS1, and is incident on multiple sub-lenses LS11, LS12, LS13, and LS14 of the first multi-channel lens LS1. Multiple holes (spaces) can be formed between the multiple legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 to ensure that the light passing through the sub-lenses is not blocked. Figure 6As shown, multiple apertures can be arranged to overlap with the central portions of multiple sub-lenses LS11, LS12, LS13, and LS14, respectively. When viewed from the top (or in a plan view), the areas of the feet CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 can be smaller than the area of ​​the apertures between them. Similarly, light emitted from the second display device DP2 can pass between the multiple feet CS2_LP1, CS2_LP2, CS2_LP3, and CS2_LP4 of the second camera mounting member CS2 and is incident on the multiple sub-lenses LS21, LS22, LS23, and LS24 of the second multi-channel lens LS2.

[0112] The number of feet CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 can be equal to the number of sub-lenses (channels) of the first multi-channel lens LS1. The number of feet CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 can be less than the number of sub-lenses (channels) of the first multi-channel lens LS1. The number of feet CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 can be less than the number of boundaries between the sub-lenses of the first multi-channel lens LS1. For example, when the first multi-channel lens LS1 has n sub-lenses, the first camera mounting member CS1 can have n or fewer feet. According to some embodiments of this disclosure, the first multi-channel lens LS1 can have four sub-lenses (channels), and the first camera mounting member CS1 can have four feet, but embodiments of this disclosure are not limited to this.

[0113] The first camera support CS1_CP may include a first leg CS1_LP1 that overlaps with the first lens boundary BD1, a second leg CS1_LP2 that overlaps with the second lens boundary BD2, a third leg CS1_LP3 that overlaps with the third lens boundary BD3, and a fourth leg CS1_LP4 that overlaps with the fourth lens boundary BD4.

[0114] The camera mount CS1_CP and the first camera CMR1 can be arranged to overlap the center of the first multi-channel lens LS1 in the third direction Z. The camera mount CS1_CP and the first camera CMR1 can be arranged to overlap with the contact points or intersections of multiple lens boundaries when viewed from above (or in a plan view). For example, as... Figure 6 As shown, the camera mount CS1_CP and the first camera CMR1 can be arranged to overlap with a cross-shaped intersection formed by multiple lens boundaries when viewed from the top (or in a plan view).

[0115] Further reference Figure 7Multiple feet CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 may have a first width W1, which is so small that it is not visible to the user. The first width W1 may be measured in a direction that intersects or is perpendicular to the direction extending from the support ring CS1_SP of the foot toward the camera bracket CS1_CP.

[0116] For example, the first width W1 can be approximately 3.0 mm or less. In this case, the diameter of the first multi-channel lens LS1 can be approximately 30 mm to 60 mm. As another example, when viewed from above (or in a plan view), the first width W1 can be approximately 1 / 13 to 1 / 20 of the diameter of the first multi-channel lens LS1. It should be noted that the dimension of the first width W1 is not limited to this and can vary depending on the design of the optical device 1.

[0117] When viewed from above (or in a plan view), the camera bracket CS1_CP may have a generally rhomboid shape. It should be understood that the embodiments according to this disclosure are not limited thereto. When viewed from above (or in a plan view), the camera bracket CS1_CP may have various shapes, such as rectangular, square, circular, elliptical, and trapezoidal.

[0118] When viewed from above (or in a plan view), the camera bracket CS1_CP can have a second width W2 that is greater than the first width W1.

[0119] The second width W2 can be measured along a diagonal direction intersecting the first direction X and the second direction Y. The second width W2 can be measured from the boundary between the first foot CS1_LP1 and the second foot CS1_LP2 to the boundary between the third foot CS1_LP3 and the fourth foot CS1_LP4, or from the boundary between the second foot CS1_LP2 and the third foot CS1_LP3 to the boundary between the first foot CS1_LP1 and the fourth foot CS1_LP4. The second width W2 can be greater than or equal to the width of the first camera CMR1.

[0120] For example, when viewed from above (or in a plan view), the second width W2 can be approximately 6.0 mm. In this case, the size of the first camera CMR1 can be approximately 5.0 mm × 5.0 mm, and the diameter of the first multi-channel lens LS1 can be approximately 40 mm to 60 mm. As another example, the second width W2 can be approximately twice the size of the first width W1. As yet another example, the second width W2 can be approximately 1 / 6 to 1 / 10 of the diameter of the first multi-channel lens LS1. It should be noted that the dimensions of the second width W2, the size of the first camera CMR1, the diameter of the first multi-channel lens LS1, etc., are not limited to these and can vary depending on the design of the optical device 1.

[0121] Reference Figure 2 and Figure 3 Similar to the first camera mounting component CS1, the second camera mounting component CS2 may also include a support ring CS2_SP, multiple feet CS2_LP1, CS2_LP2, CS2_LP3, CS2_LP4 and a camera bracket CS2_CP.

[0122] Similar to Figure 6 As shown, the support ring CS2_SP, the plurality of legs CS2_LP1, CS2_LP2, CS2_LP3 and CS2_LP4, the camera bracket CS2_CP, and the second camera CMR2 of the second camera mounting component CS2 can be arranged in substantially the same manner as the support ring CS1_SP, the plurality of legs CS1_LP1, CS1_LP2, CS1_LP3 and CS1_LP4, the camera bracket CS1_CP, and the first camera CMR1 of the first camera mounting component CS1.

[0123] The multiple legs CS2_LP1, CS2_LP2, CS2_LP3, and CS2_LP4 of the second camera mounting component CS2 can be arranged to overlap with the multiple lens boundaries of the second multi-channel lens LS2, respectively. The multiple legs CS2_LP1, CS2_LP2, CS2_LP3, and CS2_LP4 of the second camera mounting component CS2 may include fifth legs CS2_LP1, sixth legs CS2_LP2, seventh legs CS2_LP3, and eighth legs CS2_LP4 that overlap with the fifth lens boundary BD5, the sixth lens boundary BD6, the seventh lens boundary BD7, and the eighth lens boundary BD8, respectively. The fifth legs CS2_LP1, sixth legs CS2_LP2, seventh legs CS2_LP3, and eighth legs CS2_LP4 may have a width substantially equal to the width of the first legs CS1_LP1, second legs CS1_LP2, third legs CS1_LP3, and fourth legs CS1_LP4, so that they are not visible to the user.

[0124] Similarly, the support ring CS2_SP and camera bracket CS2_CP of the second camera mounting component CS2 can also be arranged to overlap with the edge portion of the second multi-channel lens LS2 and the center of the second multi-channel lens LS2, respectively, so that they are not visible to the user.

[0125] The optical device 1 has a symmetrical structure according to the user's eyes, and the second multi-channel lens LS2, the second camera mounting member CS2, and the second camera CMR2 are substantially the same as the first multi-channel lens LS1, the first camera mounting member CS1, and the first camera CMR1, respectively. Therefore, the first multi-channel lens LS1, the first camera mounting member CS1, and the first camera CMR1 will be described in detail.

[0126] Figure 8 It is along Figure 3 A sectional view taken by line A-A'.

[0127] Reference Figures 1 to 8 The first multi-channel lens LS1 may include a concave rear surface facing the first display device DP1 and the first camera mounting member CS1. The rear surfaces of the plurality of sub-lenses LS11, LS12, LS13 and LS14 forming the first multi-channel lens LS1 may form the rear surface of the first multi-channel lens LS1. The rear surface of the first multi-channel lens LS1 may be the opposite surface of the eye-side surface (the second outer surface LS11_CS, the fourth outer surface LS12_CS, the sixth outer surface LS13_CS and the eighth outer surface LS14_CS).

[0128] In cross-section, a concave internal space with a generally triangular shape protruding toward the center of the first multi-channel lens LS1 can be formed between the rear surface of the first multi-channel lens LS1 and the support ring CS1_SP of the first camera mounting member CS1. Multiple feet CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4, as well as the camera bracket CS1_CP, can be accommodated within this internal space.

[0129] As described above, the plurality of legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 of the first multi-channel lens LS1 can protrude from the support ring CS1_SP in the third direction Z. The legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 can be arranged such that they are spaced apart from the first multi-channel lens LS1 by a predetermined distance. The legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 can also be arranged such that they do not directly contact the first multi-channel lens LS1. It should be understood that embodiments according to this disclosure are not limited thereto. The legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 can also be configured such that they contact the first multi-channel lens LS1.

[0130] like Figure 8As shown, the second leg CS1_LP2 and the fourth leg CS1_LP4 can be spaced a constant distance from the rear surface of the first multi-channel lens LS1 in the third direction Z. According to some embodiments, the first leg CS1_LP1 and the third leg CS1_LP3 can also be spaced a constant distance from the rear surface of the first multi-channel lens LS1 in the third direction Z. For example, the first leg CS1_LP1, the second leg CS1_LP2, the third leg CS1_LP3, and the fourth leg CS1_LP4 can be spaced approximately 1.0 mm from the first multi-channel lens LS1. It should be understood that embodiments according to this disclosure are not limited thereto.

[0131] The camera bracket CS1_CP can overlap with the center of the first multi-channel lens LS1 in the third direction Z, and can extend in the cross section in a direction parallel to the first display device DP1. Since the rear surface of the first multi-channel lens LS1 has a concave shape, there exists a concave internal space between the camera bracket CS1_CP and the first multi-channel lens LS1 that can accommodate the first camera CMR1.

[0132] The first camera CMR1 can overlap with the center of the first multi-channel lens LS1 in the third direction Z, and can be housed in the concave space between the camera bracket CS1_CP and the rear surface of the first multi-channel lens LS1.

[0133] The camera mount CS1_CP can be arranged to form a space in which the first camera CMR1 can be housed between the center and adjacent portion of the first multi-channel lens LS1 and the camera mount CS1_CP.

[0134] In cross-section, the camera mount CS1_CP can be spaced apart from the rear surface of the first multi-channel lens LS1 in the third direction Z. The distance between the camera mount CS1_CP and the rear surface of the first multi-channel lens LS1 in the third direction Z can increase towards the center of the first multi-channel lens LS1. The distance between the camera mount CS1_CP and the rear surface of the first multi-channel lens LS1 can have a maximum value at the center of the first multi-channel lens LS1. The maximum distance between the camera mount CS1_CP and the rear surface of the first multi-channel lens LS1 can be equal to or greater than the thickness of the first camera CMR1 in the third direction Z. The maximum distance between the camera mount CS1_CP and the rear surface of the first multi-channel lens LS1 can be, but is not limited to, approximately 5.0 mm.

[0135] As described above, the multiple sub-lenses LS11, LS12, LS13, and LS14 can each provide multiple channels through which light output from the first display device DP1 or the second display device DP2 passes. The sub-lenses can amplify light emitted from specific areas of the first display device DP1 or the second display device DP2 using the same or different magnifications. The light passing through the sub-lenses can include a portion of the image to achieve a single, complete VR image, and the light can be focused onto the user's pupil to provide the user with a single, complete VR image.

[0136] For example, such as Figure 8 As shown, light output from different areas of the first display device DP1 can pass through the first multi-channel lens LS1 via different paths. The first sub-lens LS11 can provide channels from areas of the first display device DP1 (e.g., Figure 8 The light IMG1 emitted from the upper end of the first display device DP1 passes through this channel. The second sub-lens LS12 can provide a channel from another area of ​​the first display device DP1 (e.g., Figure 8 The light IMG2 emitted from the lower end of the first display device DP1 passes through this channel. At least a portion of the area of ​​the first display device DP1 may include an area that at least partially overlaps with the first sub-lens LS11 in the third direction Z, and at least a portion of another area of ​​the first display device DP1 may include an area that at least partially overlaps with the second sub-lens LS12 in the third direction Z. According to some embodiments, the third sub-lens LS13 and the fourth sub-lens LS14 may also provide a channel through which light emitted from a specific area of ​​the first display device DP1 passes. According to some embodiments of this disclosure, light passing through each of the sub-lens LS11, LS12, LS13 and LS14 may be refracted twice and reflected twice, and then provided to the user. It should be understood that the embodiments according to this disclosure are not limited thereto.

[0137] According to some embodiments of this disclosure, a light source for measuring a user's pupil can be integrated into a first camera CMR1. The light IRL output from the first camera CMR1 can be reflected away from the user's pupil and incident on the first camera CMR1. The light IRL may include an image or pattern containing the user's pupil. Based on the light IRL received by the first camera CMR1, the position of the user's pupil and the user's gaze direction can be calculated. When the light source is integrated into the first camera CMR1, the overall volume of the optical device 1 is reduced, making a compact optical device 1 possible. According to some embodiments of this disclosure, the light source can be implemented separately from the first camera CMR1 and can be mounted on a camera bracket CS1_CP adjacent to the first camera CMR1.

[0138] Reference Figure 8The optical device 1 may also include a camera connection cable CW connected to the first camera CMR1.

[0139] The camera connection cable CW can be located on the first camera mounting member CS1. In cross-section, the camera connection cable CW can be located between the first camera mounting member CS1 and the first multi-channel lens LS1. The camera connection cable CW can be located on at least one of the camera bracket CS1_CP and multiple feet CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4. For example, as... Figure 8 As shown, the camera connection cable CW can be located on the second pin CS1_LP2, but the embodiments according to this disclosure are not limited thereto. The camera connection cable CW can be located on the first pin CS1_LP1, the third pin CS1_LP3, or the fourth pin CS1_LP4.

[0140] The camera connection cable CW may be located on the surface of the camera bracket CS1_CP facing the first multi-channel lens LS1 and on the surface of at least one of the plurality of feet CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4. According to some embodiments, the camera connection cable CW may be located on another surface of the camera bracket CS1_CP facing the first display device DP1 and on another surface of at least one of the plurality of feet CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4. This other surface of the camera bracket CS1_CP and another surface of at least one of the plurality of feet CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 may be opposite to the surface of the camera bracket CS1_CP and the surface of at least one of the plurality of feet CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4.

[0141] As described above, the second multi-channel lens LS2, the second camera mounting component CS2, and the second camera CMR2 are substantially the same as the first multi-channel lens LS1, the first camera mounting component CS1, and the first camera CMR1, respectively; and therefore, some redundant descriptions will be omitted.

[0142] Figure 9 This is a cross-sectional view of an optical device according to some embodiments of the present disclosure.

[0143] about Figure 9 The described implementation methods and related information Figures 1 to 8 The implementation methods described are different, except that the light sources L1 and L2 are located on the outer surface of the first multi-channel lens LS1.

[0144] Reference Figure 9The optical device 1 may include a first light source L1 located on the outer surface of the first multi-channel lens LS1 and emitting light toward the user's pupil. In this case, the light source combined with the first camera CMR1 and the second camera CMR2 may be omitted, but the embodiments according to this disclosure are not limited thereto.

[0145] Reference Figure 3 and Figure 4 The first light source L1 can be located on one of the first outer surface LS11_NS, the third outer surface LS12_NS, the fifth outer surface LS13_NS, and the seventh outer surface LS14_NS. For example, as Figure 9 As shown, the first light source L1 may be located on the first outer surface LS11_NS of the first sub-lens LS11, but embodiments according to this disclosure are not limited thereto. When the first light source L1 is located on the first outer surface LS11_NS, light passing through the second outer surface LS11_CS is not blocked and the user's gaze is not obstructed.

[0146] The optical device 1 may also include a second light source L2, which is located on the other sub-lenses of sub-lenses LS11, LS12, LS13 and LS14, excluding the sub-lens on which the first light source L1 is located. That is, the optical device 1 may include multiple light sources L1 and L2.

[0147] The second light source L2 can be located on one of the first outer surface LS11_NS, the third outer surface LS12_NS, the fifth outer surface LS13_NS, and the seventh outer surface LS14_NS. For example, as Figure 9 As shown, the second light source L2 may be located on the third outer surface LS12_NS of the second sub-lens LS12, but embodiments according to this disclosure are not limited thereto. By further arranging the second light source L2, the position of the user's pupil can be detected more accurately.

[0148] Regarding Figures 1 to 8 The implementation methods described are different. Since the first light source L1 and the second light source L2 are located on the first multi-channel lens LS1, the distortion of the light IRL can be reduced, and the size of the first camera CMR1 and the camera bracket CS1_CP can be reduced.

[0149] First light source L1 and second light source L2 can emit light IRL for detecting the position of the user's pupil. The light IRL emitted from first light source L1 and second light source L2 can be reflected away from the user's pupil and incident on first camera CMR1. The light IRL can be, but is not limited to, infrared light or visible light. Based on the light IRL received by the camera, the position of the user's pupil and the user's gaze direction can be calculated.

[0150] Despite Figure 9The example shown illustrates two light sources, L1 and L2, as multiple light sources, but the number of light sources is not limited to this. According to some embodiments, three or more light sources may be located in the first multi-channel lens LS1. According to some embodiments, the second light source L2 may be removed, and only one first light source L1 may be located in the first multi-channel lens LS1.

[0151] about Figure 9 The described implementation methods and related information Figures 1 to 8 The described implementations are essentially the same, except that the light sources L1 and L2 are located on the outer surface of the first multi-channel lens LS1; and therefore, some redundant descriptions will be omitted.

[0152] Figure 10 Various cross-sectional views of the first leg according to some embodiments are shown.

[0153] Reference Figures 1 to 10 The cross-sectional shapes of the multiple legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 of the first camera mounting component CS1 can be substantially the same as or similar to the cross-sectional shapes of the multiple legs CS2_LP1, CS2_LP2, CS2_LP3, and CS2_LP4 of the second camera mounting component CS2. The cross-sectional shape of the first leg CS1_LP1 will be described below.

[0154] Reference Figure 10 In part (a), in cross-section, the first leg CS1_LP1 may have a rectangular shape. The first width W1 of the first leg CS1_LP1 may be greater than the first thickness T1 of the first leg CS1_LP1 in the third direction Z. According to some embodiments, the first width W1 may be equal to the first thickness T1. The first leg CS1_LP1 may have a flat upper surface and a flat lower surface. Therefore, the camera connection cable CW can be easily located on the upper or lower surface of the first leg CS1_LP1. For example, the first thickness T1 may be, but is not limited to, approximately 1.0 mm.

[0155] Reference Figure 10 In part (b), the first width W1 can be smaller than the first thickness T1. In this case, Figure 10 In the example shown in part (b), the secondary torque of the first leg CS1_LP1 in the cross-section can be greater than... Figure 10 The example shown in section (a) is expanded further. The first foot CS1_LP1 may have a flat upper surface and a raised lower surface. For example, the first thickness T1 may be, but is not limited to, approximately 3.0 mm.

[0156] Reference Figure 10In part (c), the first width W1 may be less than the first thickness T1, and the first leg CS1_LP1 may have a tapered cross-sectional shape, wherein the width in the horizontal direction decreases towards the bottom. In this case, the first width W1 may refer to the maximum width of the first leg CS1_LP1, i.e., the width of the upper surface of the first leg CS1_LP1. The side surface between the upper and lower surfaces of the first leg CS1_LP1 may be inclined in the Z direction relative to a third party. The width of the upper surface of the first leg CS1_LP1 in the horizontal direction may be substantially equal to the first width W1, and the width of the lower surface of the first leg CS1_LP1 in the horizontal direction may be less than the first width W1.

[0157] Each of the plurality of legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 of the first camera mounting component CS1 and the plurality of legs CS2_LP1, CS2_LP2, CS2_LP3, and CS2_LP4 of the second camera mounting component CS2 can have a relationship with Figure 10 The cross-sectional shapes shown are identical in one of the cross-sectional shapes. The cross-sectional shapes of the plurality of legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 of the first camera mounting member CS1, and the plurality of legs CS2_LP1, CS2_LP2, CS2_LP3, and CS2_LP4 of the second camera mounting member CS2, are not limited to these, but can vary according to the design of the optical device 1. According to some embodiments, at least one of the plurality of legs CS1_LP1, CS1_LP2, CS1_LP3, CS1_LP4, CS2_LP1, CS2_LP2, CS2_LP3, and CS2_LP4 may have a different cross-sectional shape than the other legs.

[0158] Figure 11 These are photographs showing the results of a visibility test for camera mounting components with different leg widths. Figure 12 This is a graph showing the results of visibility tests for camera mounting components with different leg widths. Figure 13 These are photographs showing the results of a visibility test of camera mount components of different widths on the legs as the user rotates their eyeballs. Figure 14 This is a graph showing the results of a visibility test for camera mounting components of different widths on the support leg as the user rotates their eyeball.

[0159] Figure 11 The test image shown is taken under the assumption that the user's eye is focused at the center of the first multi-channel lens LS1. Figure 12 The amount of light is shown based on the position (distance) from the center of the first multi-channel lens LS1.

[0160] The following test results were obtained under the conditions that the diameter of the first multi-channel lens LS1 is approximately 45 mm, the first thickness T1 is approximately 1.0 mm, and the size of the camera is 5.0 mm by 5.0 mm.

[0161] Reference Figure 11 When the first width W1 is approximately 1mm to 7mm, the first camera mounting component CS1, such as one of its legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4, is not visible in the test image. When the first width W1 is approximately 8mm to 9mm, the first camera mounting component CS1 is faintly visible in the test image. When the first width W1 is approximately 10mm, the first camera mounting component CS1 is relatively clearly visible in the test image. That is, when the first width W1 is 8mm or greater, the first camera mounting component CS1 is visible to the user.

[0162] Reference Figure 12 The horizontal axis of the graph represents the position (distance) from the center of the first multi-channel lens LS1, and the vertical axis of the graph represents the relative magnitude of the amount of light.

[0163] In the following description, a specific position range (a specific distance range) may refer to the range in which the plurality of legs CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 of the first camera mounting member CS1 are positioned relative to the center of the first multi-channel lens LS1. For example, in Figure 12 In the example shown, a specific position range may be spaced approximately 2.0 mm to 3.0 mm and -2.0 mm to -3.0 mm from the center of the first multi-channel lens LS1.

[0164] When the first width W1 is approximately 7 mm, the amount of light measured within a specific location range is approximately 8.625 to 8.875, which has a value similar to the amount of light measured around it. When the first width W1 is approximately 8 mm, the amount of light measured within a specific location range is generally similar to the amount of light measured when the first width W1 is approximately 7 mm, but may be slightly less than the amount of light measured when the first width W1 is approximately 7 mm. When the first width W1 is approximately 9 mm, the amount of light measured at a specific location range is approximately 8.3 to 8.8, which is significantly less than the amount of light measured when the first width W1 is approximately 7 mm or 8 mm. When the first width W1 is approximately 10 mm, the amount of light measured within a specific location range is approximately 7.6 to 8.8, which is much smaller than in the other examples. That is to say, it can be seen that when the first width W1 is approximately 8 mm or greater, light is blocked by the multiple feet CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 of the first camera mounting member CS1, and the first camera mounting member CS1 is visible to the user.

[0165] Figure 13 The test image shown is taken under the assumption that the user's eyeball is rotated approximately 15° relative to the center of the first multi-channel lens LS1. Figure 14 The amount of light is shown based on the position (distance) from the center of the first multi-channel lens LS1.

[0166] Reference Figure 13 When the first width W1 is approximately 1.0 mm to 3.0 mm, the first camera mounting component CS1 is almost invisible in the test image. Similarly, when the first width W1 is approximately 4.0 mm, the first camera mounting component CS1 is almost invisible or very faintly visible in the test image. When the first width W1 is 6.0 mm or greater, the first camera mounting component CS1 is visible in the test image. When the first width W1 is 8.0 mm or greater, the first camera mounting component CS1 is clearly visible in the test image. That is to say, compared with... Figure 11 The example shown is different; when the first width W1 is 4.0 mm or greater, the first camera mounting component CS1 is visible to the user.

[0167] Reference Figure 14 The horizontal axis of the graph represents the position (distance) from the center of the first multi-channel lens LS1, and the vertical axis represents the relative magnitude of the light quantity. Figure 14 In the example shown, the specific position range mentioned above can refer to a position range approximately 2.5 mm to 7.5 mm away from the center of the first multi-channel lens LS1.

[0168] When the first width W1 is approximately 3 mm, the amount of light measured within a specific position range is approximately 7.0 to 7.5, which is similar to the amount of light measured around it. On the other hand, when the first width W1 is approximately 4 mm or greater, the amount of light measured within a specific position range is significantly lower than the amount of light measured when the first width W1 is approximately 3 mm. As the first width W1 increases, the minimum amount of light measured within the position range decreases. That is, when the first width W1 is approximately 4 mm or greater, light is blocked by the multiple feet CS1_LP1, CS1_LP2, CS1_LP3, and CS1_LP4 of the first camera mounting member CS1, and the first camera mounting member CS1 is visible to the user.
