Description

Displays and wearable electronic devices including the same

[0001] Various embodiments of the present disclosure relate to wearable electronic devices, for example, to displays and wearable electronic devices including the same.

[0002] Portable electronic devices, such as electronic notebooks, portable multimedia players, mobile communication terminals, or tablet PCs, typically feature display elements and batteries, and have typically had bar-type, folder-type, or sliding-type appearances due to the shape of the display elements or batteries. Recently, as the performance of display elements and batteries has improved, they have become smaller, leading to the commercialization of wearable electronic devices that can be worn on parts of the body, such as the wrist or head. Since wearable electronic devices are directly worn on the body, portability and / or user accessibility can be improved.

[0003] Among wearable electronic devices, an electronic device that a user can wear on their face, such as a head-mounted device (HMD), is disclosed. Head-mounted devices can be usefully utilized to implement virtual reality or augmented reality. For example, a wearable electronic device can implement virtual reality by providing a three-dimensional image of a virtual space in a game enjoyed through a television or computer monitor while blocking the image of the actual space in which the user is located. Another type of wearable electronic device can provide an environment in which the user can visually perceive an actual image of the space in which the user is located, while implementing a virtual image to provide the user with various visual information, thereby providing augmented reality.

[0004] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the present disclosure.

[0005] A wearable electronic device (e.g., AR glasses) for implementing virtual reality or augmented reality may include a display for providing a virtual image to a user. The display is configured to output light corresponding to the virtual image, and the light corresponding to the virtual image output from the display may be transmitted to the user through an output member (e.g., a waveguide) of the wearable electronic device.

[0006] To ensure wearability, wearable electronic devices may require miniaturization. In such cases, it may be difficult to secure sufficient space to accommodate and / or mount components such as displays on the wearable electronic device. For example, if the display faces one side of a waveguide or is positioned above one side of the waveguide, the overall thickness of the area where the display and waveguide overlap may be excessively large, making it difficult to secure sufficient space for the display. Consequently, the space available for the display may be limited.

[0007] According to one embodiment of the present disclosure, a wearable electronic device can be provided in which the thickness of the light guide system is formed to be thin overall by providing a structure in which the display does not directly face the wave guide.

[0008] However, the problem to be solved in this disclosure is not limited to the problem mentioned above, and may be expanded in various ways without departing from the spirit and scope of this disclosure.

[0009] According to one embodiment of the present disclosure, a wearable electronic device includes a housing including a lens frame and a wearing member connected to the lens frame, a waveguide disposed on the lens frame and including a first side facing an eye of a user when the wearable electronic device is worn by a user and a second side opposite the first side, a light transmitting member at least partially overlapping the waveguide and including a third side facing substantially the same direction as the first side and a fourth side opposite the third side, and a display facing the light transmitting member and configured to output light for a virtual image, wherein light output from the display is transmitted to the waveguide through the light transmitting member, and light transmitted to the waveguide is output from the waveguide toward the eye of the user, and the display may be disposed so as not to overlap the waveguide based on a first direction from the first side of the waveguide toward the second side.

[0010] According to one embodiment of the present disclosure, a wearable electronic device includes a housing, a waveguide disposed in the housing, a light transmitting member at least partially overlapping the waveguide, and a display facing the light transmitting member and configured to output light for a virtual image, wherein the display is spaced apart from one end of the waveguide and is disposed so as not to overlap the waveguide based on a direction in which the waveguide and the light transmitting member overlap.

[0011] According to one embodiment of the present disclosure, since the display is positioned away from one end of the waveguide rather than directly facing one side of the waveguide, the overall thickness of the light guide system including the display and the waveguide can be reduced. This allows for greater design freedom regarding the display's position, as the location where the display is accommodated or mounted in a wearable electronic device is not significantly restricted.

[0012] According to one embodiment of the present disclosure, since the display and the waveguide are optically connected via the light transmitting member, the overall thickness of the light guide system can be formed thinly, thereby improving the design freedom of the waveguide. Furthermore, as the design freedom of the waveguide is improved, the waveguide can be formed to have a curvature that wraps around the user's face or a shape that is slightly tilted to match the angle of the user's face.

[0013] According to one embodiment of the present disclosure, the display is arranged on a bridge portion of a lens frame so that the position of the display does not shake even due to an external force, thereby limiting and / or reducing optical distortion of light provided from the display.

[0014] The effects that can be obtained from the present disclosure are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure belongs from the description below.

For example, when the electronic device (101) includes the main processor (121) and the auxiliary processor (123), the auxiliary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a given function. The auxiliary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0031] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state.

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

[0046] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

A signal or power may be transmitted or received between the communication module (190) and an external electronic device via the selected at least one antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0048] According to various embodiments, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0049] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0050] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service.

For example, a component configured to perform a touch and / or pressure sensing function (e.g., a touch sensor and / or a pressure sensor) may be disposed on at least a portion of the wearable member (203). The wearable electronic device (101) can control a virtual image output through the display member (201) based on information acquired through the component. For example, the sensor related to the touch and / or pressure sensing function may be configured in various ways, such as a resistive type, a capacitive type, an electromagnetic induction (EM) type, or an optical type. According to one embodiment, the component configured to perform the touch and / or pressure sensing function may have part or all of the same configuration as the input module (150) of FIG. 1.

For example, the lens structure (273) may be a prescription lens having a specified refractive power. In one embodiment, at least a portion of the lens structure (273) may be positioned behind the display member (201) (e.g., in the +Y direction). For example, the lens structure (273) may be positioned between the display member (201) and the user's eye.

[0127] In one embodiment, the housing (210) may include a hinge cover (227) that may conceal a portion of the hinge structure (229). Another portion of the hinge structure (229) may be accommodated or concealed between an inner cover (231) and an outer cover (233), which will be described later.

[0128] In one embodiment, the wearable member (203) may include an inner cover (231) and an outer cover (233). For example, the inner cover (231) is a cover 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 with low thermal conductivity, for example, a synthetic resin. In one embodiment, the inner cover (231) may include an inner side that faces the user's body. For example, the outer cover (233) may include a material (for example, a metal material) that can at least partially transmit heat, and may be coupled to face the inner cover (231).

The transparent material may be defined as a material through which light in the visible light band can pass, may not have 100% transparency, and may have a predetermined color. According to an embodiment, the light transmitting member (320) may be defined and / or referred to as another waveguide. For example, the light guide system (300) may be defined and / or interpreted as including a first waveguide (310) facing the user's eye (10) and a second waveguide (320) on which a display (330) is laminated.

[0152] According to one embodiment, the light transmitting member (320) may be composed of a material that can transmit not only light in the visible light band, but also light in other wavelength ranges, such as infrared and ultraviolet rays. In this case, the light transmitting member (320) is designed to efficiently transmit light in other wavelength ranges, thereby improving the flexibility and performance of the optical system. For example, the light transmitting member (320) is a material that can maintain high transmittance for light in various wavelength ranges, so that light in various wavelengths can be effectively processed in the optical system. According to one embodiment, the light transmitting member (320) may include a third surface (321) and a fourth surface (323). For example, the light transmitting member (320) may be a plate shape including the third surface (321) and the fourth surface (323), but is not limited thereto, and a curved surface may be formed on at least a portion of the light transmitting member (320). The third side (321) of the light transmitting member (320) may face substantially in the same direction as the first side (311) of the wave guide (310).

[0160] According to one embodiment, the second in coupler (325) and the second out coupler (327) may be arranged together on one side of the light transmitting member (320). For example, the second in coupler (325) and the second out coupler (327) may be arranged on the fourth side (323) of the light transmitting member (320). However, the arrangement of the second in coupler (325) and the second out coupler (327) is not limited thereto, and the second in coupler (325) and the second out coupler (327) may be arranged on the third side (321) of the light transmitting member (320), or the second in coupler (325) and the second out coupler (327) may be arranged on different sides (e.g., the third side (321) and the fourth side (323)) of the light transmitting member (320), respectively.

[0161] According to one embodiment, the display (330) may face the light transmitting member (320).

[0162] According to one embodiment, light generated or output from the display (330) (e.g., light for a virtual image) may be introduced into the light transmitting member (320).

[0163] Referring to the illustrated optical path (L1), light output from the display (330) and introduced into the light transmitting member (320) may be diffracted by the second in-coupler (325), totally reflected within the light transmitting member (320), and transmitted to the second out-coupler (327). The light transmitted to the second out-coupler (327) may be diffracted by the second out-coupler (327) and output toward the wave guide (310).

[0164] Referring to the illustrated optical path (L2), light output from the optical transmission member (320) and introduced into the wave guide (310) is diffracted by the first in-coupler (315), totally reflected within the wave guide (310), and transmitted to the first out-coupler (317). The light transmitted to the first out-coupler (317) can be diffracted by the first out-coupler (317) and output toward the user's eye (10).

[0165] According to one embodiment, the first direction (e.g., the Y-axis direction of FIG. 5) may be defined as a thickness direction of the wave guide (310) or the light transmitting member (320).

According to an embodiment, the first direction may also be defined as a direction in which the light transmitting member (320) overlaps or is laminated with the wave guide (310).

[0166] According to one embodiment, the display (330) may overlap with the second in-coupler (325) of the light transmitting member (320) in the first direction. The display (330) may not overlap with the second out-coupler (327), the first in-coupler (315), and the first out-coupler (317) in the first direction.

[0167] In one embodiment, the display (330) may not overlap with the wave guide (310) in the first direction. The display (330) may be positioned so as to be spaced apart from one end of the wave guide (310) and may not face the wave guide (310) in the first direction.

[0168] According to one embodiment, since the output portion (e.g., the portion where light is output) of the display (330) does not directly face the waveguide (310), the thickness formed by the display (330) and the waveguide (310) can be thinner. Compared to an exemplary embodiment in which the display directly irradiates light to one side of the waveguide, the light guide system (300) of the present disclosure, in which the display (330) provides light to the waveguide (310) through the light transmitting member (320) and does not directly face the waveguide (310), can guide light for a virtual image while the display (330) and the waveguide (310) are not stacked in the first direction, so that the overall thickness can be thinner.

[0169] According to one embodiment, the first in-coupler (315) may overlap with the second out-coupler (327) in the first direction, and may not overlap with the display (330), the second in-coupler (325), and the first out-coupler (327) in the first direction.

[0170] According to one embodiment, the first out coupler (317) may not overlap the display (330), the second in coupler (325), the second out coupler (327), and the first out coupler (327) in the first direction.

[0174] The embodiments of FIGS. 6A to 6C can be combined with the embodiments of FIGS. 1 to 5, or the embodiments of FIGS. 7A to 10.

[0175] The configurations of the embodiments of FIGS. 6A to 6C may be partially or entirely identical to the configurations of the embodiments of FIGS. 1 to 5, or the configurations of the embodiments of FIGS. 7A to 10.

[0176] Referring to FIGS. 6A to 6C, a state in which a light transmitting member (320) and a display (330) overlap in a first direction (e.g., Y-axis direction) is illustrated. The first direction may be defined as a thickness direction of the light transmitting member (320). For example, the first direction may include a direction from the third side (321) of the light transmitting member (320) toward the fourth side (323), or the opposite direction.

[0177] According to one embodiment, the light transmitting member (320) may include a second in-coupler (325) and a second out-coupler (327). The light transmitting member (320) may be defined and / or referred to as a light transmitting lens.

[0178] According to one embodiment, the second in-coupler (325) may include a metalens. The second in-coupler (325) may adjust the direction and / or phase of light output from the display (330) and introduced into the light transmitting member (320), so that the light is totally reflected within the light transmitting member (320) and transmitted toward the second out-coupler (327).

[0179] According to one embodiment, the second out-coupler (327) may include a meta lens. The second out-coupler (327) may adjust the direction and / or phase of light totally reflected within the light transmitting member (320) so that the light is output from the light transmitting member (320) and introduced into a wave guide (e.g., wave guide (310) of FIG. 5).

[0180] According to one embodiment, the display (330) can output a plurality of lights (L1, L2, L3). For example, the display (330) can generate lights (L1, L2, L3) at various angles and introduce them into the light transmitting member (320). Each of the lights (L1, L2, L3) output from the display (330) can travel along different paths within the light transmitting member (330).

[0181] According to one embodiment, the light transmitting member (330) may be configured to expand the size of a virtual image formed by each of the lights (L1, L2, L3) (e.g., the size of the virtual image perceived by the user) based on the inflow of each of the lights (L1, L2, L3) into and output from the light transmitting member (330), but is not limited thereto.

[0182] Referring to FIGS. 6A and 6B, the second input coupler (325) may include a transmissive meta-lens (3251) and a reflective mirror (3252). For example, lights (L1, L2, L3) output from the display (330) may be refracted while passing through the transmissive meta-lens (3251), reflected by the reflective mirror (3252), and refracted again while passing through the transmissive meta-lens (3251). This may be done. At this time, the lights (L1, L2, L3) may be refracted when passing through the transmissive meta-lens (3251) again. In this way, the lights (L1, L2, L3) are refracted by the transmissive metalens (3251) and reflected by the mirrors (3252), and their phases and / or angles are adjusted to have an angle suitable for total reflection within the light transmitting member (320), but are not limited thereto.

[0183] Referring to FIGS. 6A and 6C, a reflective meta-lens (3253) may be included. For example, lights (L1, L2, L3) output from the display (330) may be reflected by the reflective meta-lens (3253).
