Patent Description:
With the development of electronic and communication technologies, electronic devices can be reduced in size and weight to such an extent that the electronic devices can be used without great inconvenience even when the electronic devices are worn on a user's body. For example, wearable electronic devices, such as a head mounted device (HMD), a smartwatch (or band), a contact lens-type device, a ring-type device, a glove-type device, a shoe-type device, or a clothing-type device, are commercially available. Since the wearable electronic devices are directly worn on a user's body, portability and user accessibility may be improved.

A head mounted device is a device used in the state of being worn on a user's head or face and may provide augmented reality (AR) to the user. For example, a head mounted device providing augmented reality may be implemented in the form of glasses, and may provide information about an object in the form of an image or text to the user in at least a partial space of the user's field of view. The head mounted device may provide virtual reality (VR) to the user. For example, by outputting independent images to the user's both eyes, respectively, and outputting a content provided from an external input to the user in the form of an image or sound, the head mounted device may provide an excellent sensation of immersion.

Document <CIT> discloses a glasses-type electronic device with a flexible printed circuit board.

In an electronic device for virtual reality or augmented reality (hereinafter referred to as "AR"), a main circuit board (hereinafter, referred to as a "main PCB") is located in the center (above the forehead) of an AR device, so that the AR device is mainly configured in a goggles type, rather than in a glasses type. The glasses type has a simple monocular configuration or a simple camera-free configuration. In addition, since the main PCB is located in the center of the AR device, the AR device may have a large size. In order to develop a slim and lightweight glasses-type AR device, a main PCB may be located in a temple and may be connected to modules, such as a camera and a display, using a flexible printed circuit board (hereinafter, referred to as an "FPCB"). However, there are restrictions due to the spatial limitation of the temples.

As the number of data lines to be drawn out from the main PCB and each module increases, the number of FPCBs connecting each module to the main PCB, the overall width of the FPCB, and/or the number of layers of the FPCB may increase, which may result in a decrease in flexibility. This may make it difficult to fold the temples of the glasses-type AR device.

Since it is necessary to dispose connectors for connecting FPCBs to respective modules on the PCB, the PCB becomes larger, which causes an increase in the size of the AR device and which makes it necessary to couple several different FPCBs in the assembly step of coupling the FPCBs to the main PCB, resulting in a complicated structure. Thus, it takes a long time to assemble, which may cause degradation in mass productivity.

In addition, each FPCB includes one or more layers, and the same material used for all the layers of the FPCB. In the AR device structure in which high-speed signals such as MIPI, PCIe, and RF signals are individually connected to the left eye or the right eye, there may be a signal loss due to the multiple FPCBs.

According to various embodiments of the disclosure, a glasses-type AR device is miniaturized and lightened in order to improve portability and convenience for a user, and may include integrated components in a small space for high performance.

According to various embodiments of the disclosure, by using a single FPCB when connecting a main system and different modules, it is possible to provide a glasses-type AR device capable of transmitting a low-loss, high-speed signal while being miniaturized.

However, the problems to be solved in the disclosure are not limited to the above-mentioned problems, and may be variously expanded without departing from the scope of the invention as defined by the appended claims.

According to various embodiments of the disclosure, a glasses-type electronic device may include a housing, a lens frame unit disposed in the housing, a camera module and a display module disposed in the lens frame unit, a first wearing unit extending from one end of the lens frame unit and including a first PCB disposed therein, a second wearing unit extending from the other end of the lens frame unit and including a second PCB disposed therein, and a flexible PCB (FPCB) extending from the first PCB through the lens frame unit and connected to the second PCB.

The invention provides a glasses-type electronic device according to claim <NUM> including a lens frame unit, a first wearing unit extending from one end of the lens frame unit and including a first PCB disposed therein, a second wearing unit extending from the other end of the lens frame unit and including a second PCB disposed therein, and a flexible PCB (FPCB) extending from the first PCB through the lens frame unit and connected to the second PCB. The FPCB is electrically connected to each of modules for a first signal and a second signal, a first wiring line of the FPCB that is connected to the module for the first signal is located in at least a portion of an uppermost layer or a lowermost layer of the FPCB, and a second wiring line of the FPCB that is connected to the module for the second signal is located in at least a portion of an inner layer of the FPCB, wherein the first signal has a speed higher than that of the second signal.

Various embodiments of the disclosure may propose a glasses-type electronic device including a flexible PCB (FPCB), a main PCB electrically connected to an end of the FPCB, and a sub-PCB electrically connected to the other end of the FPCB. At least a partial area of the FPCB may include a connector configured to be connectable to one or more components of the glasses-type electronic device. The FPCB may include a plurality of layers configured to provide a power or signal wiring line and may include, in the plurality of layers, a first wiring line for a first signal, which is disposed in at least one of the uppermost layer or the lowermost layer of the layers that provide the signal wiring line, and a second wiring line for a second signal, which is disposed in an inner layer disposed between the uppermost layer and the lowermost layer, wherein the first signal may have a higher speed than that of the second signal.

In an AR electronic device according to various embodiments of the disclosure, by using a single FPCB, it is possible to miniaturize the AR electronic device and to improve high-speed signal transmission.

For example, each lens structure <NUM> may face one surface (e.g., the second outer surface 231b in <FIG>) of the corresponding display member <NUM>.

According to various embodiments, the housing <NUM> may include hinge covers <NUM> each of which is capable of concealing a portion of the corresponding hinge structure <NUM>. The other portion of each hinge structure <NUM> may be accommodated or concealed between an inner case <NUM> and an outer case <NUM>, which will be described later.

According to various embodiments, each wearing member <NUM> may include an inner case <NUM> and an outer case <NUM>. The inner case <NUM> is, for example, a case configured to face the user's body or to come into direct contact with the user's body, and may be made of a material having a low thermal conductivity (e.g., a synthetic resin). According to an embodiment, the inner case <NUM> may include an inner surface (e.g., the inner surface 231c in <FIG>) facing the user's body. The outer case <NUM> may include, for example, a material (e.g., a metal material) capable of at least partially transferring heat, and may be coupled to face the inner case <NUM>. According to an embodiment, the outer case <NUM> may include an outer surface (e.g., the outer surface 231d in <FIG>) opposite to the inner surface 231c. In an embodiment, at least one of the circuit boards <NUM> or the speaker modules <NUM> may be accommodated in a space separated from the battery <NUM> within the corresponding wearing member <NUM>. In the illustrated embodiment, the inner case <NUM> may include a first case 231a including the circuit board <NUM> and/or the speaker module <NUM> and a second case 231b configured to accommodate the battery <NUM>, and the outer case <NUM> may include a third case 233a coupled to face the first case 231a and a fourth case 233b coupled to face the second case 231b. For example, the first case 231a and the third case 233a (hereinafter, "first case parts 231a and 233a") may be coupled to accommodate the circuit board <NUM> and/or the speaker module <NUM>, and the second case 231b and the fourth case 233b (hereinafter, "second case parts 231b and 233b") may be coupled to accommodate the battery <NUM>.

According to various embodiments, the first case parts 231a and 233a may be rotatably coupled to the lens frame unit <NUM> via the hinge structures <NUM>, and the second case parts 231b and 233b may be connected to or mounted on the ends of the first case parts 231a and 233a via the connection structures <NUM>. In some embodiments, the portions of the connection structures <NUM> that come into contact with the user's body may be made of a material having low thermal conductivity (e.g., an elastic material such as silicone, polyurethane, or rubber), and the portions that do not come into contact with the user's body may be made of a material having a high thermal conductivity (e.g., a metal material). For example, when heat is generated from the circuit boards <NUM> or the batteries <NUM>, the connection structures <NUM> block heat from being transferred to portions that come into contact with the user's body, and may distribute or release heat through the portions that do not come into contact with the user's body. According to an embodiment, the portions of the connection structures <NUM> that are configured to come into contact with the user's body may be interpreted as portions of the inner cases <NUM>, and the portions of the connection structures <NUM> that do not come into contact with the user's body may be interpreted as portions of the outer cases <NUM>. According to an embodiment (not illustrated), the first case 231a and the second case 231b may be integrally configured without the connection structure <NUM>, and the third case 233a and the fourth case 233b may be integrally configured to each other without the connection structure <NUM>. According to various embodiments, in addition to the illustrated components, other components (e.g., the antenna module <NUM> of <FIG>) may be further included, and information about an object or environment may be provided from an external electronic device (e.g., the electronic device <NUM> or <NUM> or the server <NUM> in <FIG>) using a communication module <NUM> via a network (e.g., the first network <NUM> or the second network <NUM> in <FIG>).

According to an embodiment, an FPCB (e.g., the FPCB <NUM> in <FIG>) in the electronic device <NUM> may be further connected to an eye tracking module.

Referring to <FIG>, the electronic device <NUM> may include the components accommodated in the housing <NUM> (e.g., at least one circuit board <NUM>, a flexible PCB (FPCB), a wireless communication module <NUM>, and at least one battery <NUM>, at least one speaker module <NUM>, and a camera module <NUM>) and a connection member <NUM> connected to the circuit board <NUM>.

All or some of the components of the housing <NUM> of <FIG> may be the same as the configurations of the display member <NUM>, the lens frame unit <NUM>, the wearing member <NUM>, the hinge structure <NUM>, and the power transmission structure <NUM> described with reference to <FIG>.

<FIG> is a view illustrating an FPCB structure according to an embodiment of the disclosure.

According to various embodiments, the electronic device <NUM> may include a main PCB (e.g., the first PCB <NUM> in <FIG>) among one or more circuit boards <NUM>. The first PCB (e.g., the first PCB <NUM> in <FIG> or the first PCB <NUM> in <FIG>) may be a board including at least one layer. The first PCB may be connected to the components accommodated in the housing <NUM> via a hotbar (e.g., the hotbar <NUM> of <FIG>) or a connector (not illustrated). The first PCB (e.g., the first PCB <NUM> in <FIG> or the first PCB <NUM> in <FIG>) may be located in one temple (e.g., the right temple in <FIG>). At least one electronic component (e.g., the electronic component <NUM> of <FIG>) (e.g., an AP memory, a CAM PMIC, or an AMP) may be mounted on the first PCB (e.g., the first PCB <NUM> in <FIG> or the first PCB <NUM> in <FIG>). The first PCB (e.g., the first PCB <NUM> of <FIG> or the first PCB <NUM> of <FIG>) may be connected to a battery (e.g., the battery <NUM> in <FIG>) and an SPK located at a terminal end of the temple.

According to various embodiments, the electronic device <NUM> may include a sub-PCB (e.g., the second PCB <NUM> in <FIG>) among one or more circuit boards <NUM>. The second PCB (e.g., the second PCB <NUM> in <FIG> or the second PCB <NUM> in <FIG>) may be a board including at least one layer. The second PCB (e.g., the second PCB <NUM> in <FIG> or the second PCB <NUM> in <FIG>) may be connected to components accommodated in the housing <NUM> via a hotbar (not illustrated) or a connector (e.g., the connector <NUM> in <FIG>). The second PCB may be located on the other temple (e.g., the left temple in <FIG>). At least one electronic component (e.g., the electronic component <NUM> in <FIG>) (e.g., a touch IC, an IR driver, a Wi-Fi device, a power supply, an AMP, or an MIC) may be mounted on the second PCB (e.g., the second PCB <NUM> in <FIG> or the second PCB <NUM> in <FIG>). The second PCB (e.g., the second PCB <NUM> in <FIG> or the second PCB <NUM> in <FIG>) may be connected to a battery (e.g., the battery <NUM> in <FIG>) and an SPK located at the terminal end of the temple. A single FPCB (e.g., the FPCB <NUM> in <FIG>) may electrically connect the first PCB (e.g., the first PCB <NUM> in <FIG>) and the second PCB (e.g., the second PCB <NUM> in <FIG>) to each other, and according to an embodiment, may be electrically connected to a battery(s) located at the terminal end of the temple.

According to various embodiments, the electronic device <NUM> may include an FPCB (e.g., the FPCB <NUM> in <FIG>) electrically connected to a first PCB (e.g., the first PCB <NUM> in <FIG>), a second PCB (e.g., the second PCB <NUM> in <FIG>), and components accommodated in the housing <NUM>. The FPCB (e.g., the FPCB <NUM> in <FIG>) may be located on at least some of the display members <NUM>, the lens frame unit <NUM>, the wearing members <NUM>, the hinge structures <NUM>, and the power transmission structures <NUM> described with reference to <FIG>.

According to various embodiments, the first PCB <NUM> located at the right end of the glasses (e.g., the +X-axis direction in <FIG>) and including a main system and the second PCB (e.g., the second PCB <NUM> in <FIG>) located at the left end of the glasses (e.g., the -X-axis direction in <FIG>) and including a sub-system including a charging circuit, batteries (e.g., the first battery 243a and the second battery 243b in <FIG>) and/or a speaker (e.g., the SPK <NUM> in <FIG>) may be connected to each other via a single FPCB (e.g., the FPCB in <FIG>). The FPCB (e.g., the FPCB <NUM> of <FIG>) may be electrically connected to the first PCB (e.g., the first PCB <NUM> in <FIG>) or the second PCB (e.g., the second PCB712 in <FIG>) via a hotbar (e.g., the hotbar <NUM> in <FIG>) or a connector.

<FIG> illustrates a method of connecting FPCBs and modules to each other in a glasses-type electronic device.

Referring to <FIG>, a connection structure of a main PCB (e.g., the main PCB 711a in <FIG>), a multi-layered FPCBs (e.g., the FPCBs 720a in <FIG>), and FPCBs and respective modules (e.g., an electronic component(s) <NUM> in <FIG>) in a conventional glasses-type device is illustrated. A one-to-one connection of a plurality of modules (e.g., the electronic component(s) <NUM> in <FIG>) with respective FPCBs (e.g., FPCB 720a of <FIG>) in the main PCB (e.g., the main PCB 711a in <FIG>) is illustrated.

Referring to <FIG>, the main PCB (e.g., the main PCB 711a in <FIG>) and the sub-PCB (e.g., the sub-PCB 712a in <FIG>) may include one or more components.

Referring to <FIG>, each module (e.g., the electronic component(s) <NUM> in <FIG>) may include, for example, a camera CAM, a microphone MIC, a display, or a sensor. Each module (e.g., electronic component(s) <NUM> of <FIG>) may be connected to the main PCB (e.g., the main PCB 711a in <FIG>) by a connector (e.g., the CON 703a in <FIG>).

Referring to <FIG>, when a connector (e.g., the CON 703a in <FIG>) is used for each module (e.g., the electronic component(s) <NUM> in <FIG>), a plurality of connectors (e.g., the CON 703a in <FIG>) 703a)) are used. Thus, since the size of the main PCB (e.g., the main PCB 711a of <FIG>) is increased, and the total thickness is increased due to the use of respective FPCBs (e.g., the FPCBs 720a in <FIG>), it may be difficult for the main PCB to pass through a hinge (e.g., the hinge structure <NUM> in <FIG>), and it may be difficult to bend the temple.

<FIG> illustrates a method for connecting an FPCB and the modules to each other according to an embodiment of the disclosure.

Referring to <FIG>, a first PCB (e.g., the first PCB <NUM> in <FIG>) may be connected to a single FPCB (e.g., the FPCB <NUM> in <FIG>) via a single hotbar (e.g., the hotbar <NUM> in <FIG>) (or a connector). Compared with the embodiment of <FIG> in which a plurality of FPCBs (e.g., FPCBs 720a in <FIG>) are used, since the first PCB (e.g., the first PCB <NUM> in <FIG>) is connected using the single FPCB (e.g., the FPCB <NUM> in <FIG>), and it is possible to minimize the size of the first PCB (e.g., the first PCB <NUM> in <FIG>) and it is possible to connect the first PCB to a plurality of modules (e.g., the electronic component(s) <NUM> in <FIG>) using a plurality of layers included in the single FPCB (e.g., the FPCB <NUM> in <FIG>). For example, when using the single FPCB (e.g., the FPCB <NUM> in <FIG>), since the thickness of wiring lines passing through a hinge from a temple is reduced compared with that in the case in which a plurality of FPCBs (e.g., the FPCBs <NUM> in <FIG>) are used as in <FIG>, it may be easy to wire the display members, and the folding or unfolding operation of temples may be facilitated.

According to various embodiments, the single FPCB (e.g., the FPCB <NUM> in <FIG>) may include a rigid area <NUM>, which is less flexible than other areas, and a flexible area <NUM> higher flexible than the rigid area to be bendable, and may include a rigid/flexible area <NUM> in which areas having different flexibility are compositely coupled to each other without a separate connector. A difference in partial flexibility in the single FPCB (e.g., the FPCB <NUM> in <FIG>) may be implemented through a difference in material or by a partially disposed auxiliary substrate. According to an embodiment, connectors (e.g., the CONs <NUM> in <FIG>) connected to the display and the camera module (e.g., the electronic component(s) <NUM> in <FIG>) are located in the middle of the FPCB (e.g., the FPCB <NUM> in <FIG>), and some circuits such as sensors may be mounted on the rigid area <NUM>. The flexible region <NUM> may be flexible to allow the temples to be folded or unfolded.

<FIG> illustrates wiring lines in respective layers of an FPCB according to an embodiment of the disclosure.

Referring to <FIG>, a single FPCB (e.g., the FPCB <NUM> in <FIG>) includes a plurality of layers (e.g., layers <NUM> to <NUM> in <FIG> or layers <NUM> to <NUM> (<NUM> to <NUM>) in <FIG>) for wiring, and in each wiring layer, wiring lines are disposed for transmission of power or various signals.

According to the invention, respective wiring layers (e.g., layers <NUM> to <NUM> in <FIG> or layers <NUM> to <NUM> (<NUM> to <NUM>) in <FIG>) in the single multi-layered FPCB (e.g., the FPCB <NUM> in <FIG>) are disposed in consideration of signal transmission efficiency or power efficiency by being connected to one or more components such as a power source and a sensor. For example, in the case of the multi-layered FPCB (e.g., the FPCB <NUM> in <FIG>), it is possible to achieve various combinations of a position at which the electronic components (e.g., the electronic component(s) <NUM> in <FIG>), such as a display and a camera, are connected to wiring lines of the FPCB, a final destination as to whether the FPCB (e.g., the FPCB <NUM> in <FIG> is connected to the front portion of AR glasses or hinges, layers in which a wiring line for high-speed signal transmission and a power wiring line (e.g., layers <NUM> and <NUM> in <FIG>), which are separated from each other, are located in the FPCB (e.g., the FPCB <NUM> in <FIG>), or the like.

For example, a layer for wiring lines for transmitting high-speed signals, such as a MIPI signal for a display or a camera module, a PCIe interface for a graphics card, SSD, or the like, or an RF for a wireless communication signal such as a Wi-Fi antenna signal, are located in the uppermost layer or the lowermost layer in a flexible area of the single FPCB (e.g., the FPCB <NUM> in <FIG>). For example, the layer of a wiring line for high-speed signal transmission may be layer <NUM> or layer <NUM> in <FIG>, and may be layer <NUM> (<NUM>) or layer <NUM> (<NUM>) in <FIG>. An insulating layer (not illustrated) for shielding may be disposed between respective layers, the layer exposed as the top surface or the bottom surface of the FPCB (e.g., the FPCB <NUM> in <FIG>) (which may be, for example, layer <NUM> or layer <NUM> in <FIG> or layer <NUM> (<NUM>) or layer <NUM> (<NUM>) in <FIG>) may at least partially function as an electromagnetic shielding structure (e.g., an EMI sheet). The layers (e.g., layers <NUM> to <NUM> in <FIG> or layers <NUM> to <NUM> (<NUM> to <NUM>) in <FIG>) disposed between wiring layers for high-speed signal transmission (e.g., layers <NUM> and <NUM> in <FIG> or layer <NUM> (<NUM>) and layer <NUM> (<NUM>) in <FIG>) may provide, for example, a power wiring line (e.g., the wiring line of layer <NUM> in <FIG>), an interface signal wiring line (e.g., a wiring line in layer <NUM> in <FIG>) and/or grounds for impedance matching (e.g., wiring lines or grounds in layer <NUM> and layer <NUM> in <FIG>). In each layer, other signals including the corresponding signal may be additionally located.

According to various embodiments, the first PCB (e.g., the first PCB <NUM> in <FIG>) and the second PCB (e.g., the second PCB <NUM> in <FIG>) are electrically connected to each other via the single FPCB (e.g., the FPCB <NUM> in <FIG>), and between the first PCB (e.g., the first PCB <NUM> in <FIG>) and the second PCB (e.g., the second PCB <NUM> in <FIG>), one or more wearing members 203a and 203b, one or more hinge structures <NUM>, and components 810a to 810i disposed on the lens frame unit <NUM> may be electrically connected to the first PCB (e.g., the first PCB <NUM> in <FIG>)) and the second PCB (e.g., the second PCB <NUM> in <FIG>) via the single FPCB (e.g., the FPCB <NUM> in <FIG>). For example, a plurality of modules (e.g., the electronic component(s) <NUM> in <FIG>) may include at least one of a display/MIC 810a, HeT CAM 810b, Et CAMs 810d and <NUM>, IR LEDs 810c and 810f, and sensors 810e and may be electrically connected to the first PCB (e.g., the first PCB <NUM> in <FIG>) or the second PCB (e.g., the second PCB <NUM> in <FIG>) via the FPCB (e.g., the FPCB <NUM> in <FIG>). The FPCB (e.g., the FPCB <NUM> of <FIG>) connected to the first PCB (e.g., the first PCB <NUM> in <FIG>) may include a plurality of layers (e.g., layers <NUM> to <NUM> in <FIG>). For example, respective wiring lines included in the FPCB (e.g., the FPCB <NUM> in <FIG>) may include a layer for a high-speed signal (e.g., layers <NUM> and <NUM> in <FIG>), and a ground for impedance matching (e.g., layers <NUM> and <NUM> in <FIG>), a layer for an interface signal (e.g., layer <NUM> in <FIG>), and a layer for main power (e.g., layer <NUM> in <FIG>). Each component and the name of the same described in <FIG> are described as an example for convenience of description and are not limited to those described in the drawings.

According to various embodiments, materials of the plurality of layers (e.g., layers <NUM> to <NUM> in <FIG>) of the FPCB (e.g., the FPCB <NUM> in <FIG>) may be different from each other. In general, in the FPCB (e.g., the FPCB <NUM> in <FIG>), the same material may be used even for wiring lines of different layers. However, in consideration of the electrical characteristics or losses according to materials, some layers (e.g., a layer that provides a wiring line for high-speed signal transmission) may have a material different from those of other layers (e.g., a layer that provides a wiring line for power or interface). For example, when a material having a dielectric constant lower than that of other wiring layers is used in a wiring layer for high-speed signals (e.g., layers <NUM> and <NUM> in <FIG>) used for wiring lines of high-speed signals, it is possible to transmit high-speed signals with low loss rates.

Referring to Table <NUM>, it is possible to compare the loss rates when a low Df material and a normal Df material are used as wiring materials for FPCBs (e.g., the FPCB <NUM> in <FIG>). For example, it can be seen that, in the case of a Wi-Fi signal, when the low Df material is used at <NUM> frequency, the loss rate is <NUM> in a rigid area, whereas when the normal Df material is used, the loss rate is <NUM>, which is higher than that in the case where the low DF material is used. For example, when a communication module used for transmission of high-speed signals, such as a Wi-Fi signal, a PCIe signal, or an RF signal, and an FPCB (e.g., the FPCB <NUM> in <FIG>) are connected to each other, the communication module and the FBCB may be connected to each other via a wiring line located in the outer layer (e.g., layers <NUM> and <NUM>) in <FIG>) of the FPCB (e.g., the FPCB <NUM> in <FIG>). The layer for a high-speed signal wiring line of the FPCB (e.g., the FPCB <NUM> in <FIG>) is formed of a material having a dielectric constant lower than that of an inner layer (e.g., layers <NUM> to <NUM> in <FIG>), wherein the material of each of the wiring line layers (e.g., the layers <NUM> to <NUM> in <FIG>) may be appropriately selected in consideration of a signal to be transmitted therethrough. A low Df material may be a low dielectric loss material applicable to a coverlay or a prepreg (PPG), but is not limited thereto.

<FIG> illustrates a layout for respective layers of an FPCB according to an embodiment of the disclosure.

Referring to <FIG>, the layout of respective layers (e.g., layers <NUM> to layer <NUM> (<NUM> to <NUM>) in <FIG>) of an FPCB is illustrated. For example, in <FIG>, when a wiring line or a wiring layer (e.g., layer <NUM> (<NUM>) or layer <NUM> (<NUM>) in <FIG>) located on an outer layer of the FPCB (e.g., the FPCB <NUM> in <FIG>) is provided with wiring lines for high-speed signals (e.g., MIPI signal, PCIe signal, and/or an RF signal) between a first PCB (e.g., the first PCB <NUM> in <FIG>) and a first rigid area of <FIG> (e.g., rigid area <NUM> in <FIG>), the section (e.g., <NUM> in <FIG>) from the first rigid area (e.g., the rigid area <NUM> in <FIG>) to a second PCB (e.g., the second PCB <NUM> in <FIG>) may have a width smaller than that in the section (e.g., <NUM> in <FIG>) between the first PCB (e.g., the first PCB <NUM> in <FIG>) and the first rigid area (e.g., <NUM> in <FIG>). For example, since at least some of the signal wiring lines corresponding to MIPI signal may be omitted, the width of the FPCB in the section (e.g., <NUM> in <FIG>) between the first rigid area (e.g., <NUM> in <FIG>) and the second PCB (e.g., <NUM> in <FIG>) can be decreased and the flexibility can be increased. As an example, the FPCB (e.g., the FPCB <NUM> in <FIG>) is connected to the second PCB (e.g., the second PCB <NUM> in <FIG>) while being connected to respective modules (e.g., 810a to 810i in <FIG>), so that signals are drawn to the respective modules. Therefore, the width of the FPCB (e.g., FPCB <NUM> in <FIG>) becomes smaller gradually or stepwise toward the second PCB (e.g., the second PCB <NUM> in <FIG>). In some embodiments, the width of the FPCB (e.g., the FPCB <NUM> in <FIG>) may be substantially uniform between the first PCB (e.g., the first PCB <NUM> in <FIG>) and the second PCB (e.g., the second PCB <NUM> in <FIG>), and in this case, the inner wiring lines may be more simplified toward the second PCB (e.g., the second PCB <NUM> in <FIG>). For example, the wiring lines in a partial section (e.g., <NUM> in <FIG>) of the FPCB (e.g., the FPCB <NUM> in <FIG>) adjacent to the second PCB (e.g., the second PCB <NUM> in <FIG>) may be more simplified than those of another partial section (e.g., <NUM> in <FIG>) of the FPCB (e.g., the FPCB <NUM> in <FIG>) adjacent to the first PCB. For example, there may be empty portions in which wiring lines are not present, such as the end portions of layer <NUM> (<NUM>) and layer <NUM> (<NUM>) in FIG. 9A, and the corresponding layer in which wiring lines are not present may be at least partially deleted to improve the bendability or flexibility of the FPCB (e.g., the FPCB <NUM> in <FIG>). In another embodiment, when the width of the FPCB (e.g., FPCB <NUM> in <FIG>) is reduced in the section in which wiring lines are simplified (e.g., <NUM> in <FIG>), a margin space can be secured in an area passing through the hinge. Since a coaxial cable connected to a Wi-Fi antenna is able to pass through the secured margin space, it is possible to reduce transmission loss in wireless communication.

<FIG> illustrate a dedicated FPCB for power reinforcement according to an embodiment of the disclosure.

According to various embodiments, a wiring line for main power (e.g., layer <NUM> in <FIG>) may be located in an inner layer of the single FPCB (e.g., the FPCB <NUM> in <FIG>). By additionally locating a conductive member (e.g., <NUM> in <FIG>) in an upper empty space of the rim (e.g., the lens frame unit <NUM> of <FIG>) as in <FIG> in order to improve an IR drop of power in the FPCB (e.g., the FPCB <NUM> in <FIG>), it is possible to improve an IR drop in the FPCB (e.g., the FPCB <NUM> in <FIG>) and to enhance the degree of freedom of signal wiring by separating a power supply separately. For example, the conductive member (e.g., <NUM> in <FIG>) may include an FPCB or a coaxial cable. At this time, in a single FPCB (e.g., the FPCB <NUM> in <FIG>), a power wiring line may be drawn out to the outer layer through a via and may be connected to a conductive member (e.g., <NUM> in <FIG>) via a board-to-board connector or a contact connector, or through soldering.

The electronic device <NUM> of the disclosure is, for example, a glasses-type AR device, wherein a first PCB (e.g., the first PCB <NUM> in <FIG>) including a main system may be disposed in at least one wearing member <NUM>, and wiring lines from the first FPCB (e.g., the first PCB <NUM> in <FIG>) to respective components (e.g., a camera, a display, an audio module, and a sensor) and/or a second PCB (e.g., the second PCB <NUM> in <FIG>) may be provided using a single multi-layered FPCB (e.g., the FPCB <NUM> in <FIG>). Even when wired through a hinge structure <NUM>, the FPCB (e.g., the FPCB <NUM> in <FIG>) may have the effects of minimizing the sizes of the PCBs, reducing the size of the glasses, and simplifying the assembly process while enabling the temples to be smoothly folded or unfolded. In addition, in the FPCB (e.g., the FPCB <NUM> in <FIG>), when the material of the uppermost layer or the lowermost layer among the layers providing signal wiring lines is different from that of the inner layers, it is possible to transmit a high-speed signal with low loss.

According to various embodiments of the disclosure, a glasses-type electronic device (e.g., the electronic device <NUM> in <FIG>) may include a housing (e.g., the housing <NUM> in <FIG>), a lens frame unit (e.g., the lens frame unit <NUM> in <FIG>) provided as a part of the housing, at least one camera module (e.g., the camera module <NUM> in <FIG>) or at least one display module (e.g., the display module <NUM> in <FIG>) disposed on the lens frame unit, a first wearing unit (e.g., the first wearing member 203a in <FIG>) extending from one end of the lens frame unit and including a first PCB disposed therein, a second wearing unit (e.g., the second wearing member 203b in <FIG>) extending from the other end of the lens frame unit and including a second PCB disposed therein, and a flexible PCB (FPCB) (e.g., the FPCB <NUM> in <FIG>) extending from the first PCB through the second lens frame unit to be electrically connected to the second PCB. Inside the lens frame unit, the FPCB may be electrically connected to at least one of the camera module or the display module.

According to various embodiments of the disclosure, the first wiring line may be formed of a material different from that of the second wiring line.

According to various embodiments of the disclosure, the display module may include a first display module and a second display module, the camera module may include a first camera module and a second camera module, and the first display module, and the second display module, the first camera module, and the second camera module may be electrically connected to any one of the first PCB and the second PCB via the FPCB.

According to various embodiments of the disclosure, the FPCB may be further electrically connected to an eye tracking module.
