[0056] An embodiment of the present disclosure will be described in more detail below with reference to the attached drawings.
[0057] FIG. 1 is a drawing for illustrating an electronic device (100) and a power supply (200) according to one embodiment.
[0058] The electronic device (100) can receive power from the power supply (200).
[0059] The electronic device (100) can perform various operations using the supplied power. There may be various ways in which the electronic device (100) uses the power received from the power supply (200).
[0060] For example, the electronic device (100) may be a device that supplies power when connected to a power supply (200). The electronic device (100) may operate using power received from the power supply (200). If the electronic device (100) is disconnected from the power supply (200), the electronic device (100) may not operate.
[0061] For example, the electronic device (100) may be a rechargeable device. The electronic device (100) may perform a charging function using power received through a power supply (200). The power supply (200) may charge an internal battery using power received from the electronic device (100). The power supply (200) may perform a function of providing services to the user along with a charging function while connected to the electronic device (100). The electronic device (100) may perform a service function using the charged power while disconnected from the power supply (200).
[0062] The electronic device (100) may be a terminal device that provides a specific service to a user. For example, the electronic device (100) may represent an XR (Extended Reality) device, a VR (Virtual Reality) device, an AR (Augmented Reality) device, a MR (Mixed Reality) device, etc.
[0063] The power supply unit (200) may be a device that supplies power. For example, the power supply unit (200) may represent a power source device, a power connector device, a rechargeable battery, etc.
[0064] The electronic device (100) and the power supply (200) can be connected through a connector (300). The connector (300) may include at least one of a communication line for exchanging information with the electronic device (100) and the power supply (200) or a power line for transmitting power.
[0065] For example, the connector (300) may include both power lines and communication lines.
[0066] For example, the connector (300) may include only a power line.
[0067] The connector (300) may be described as a cable or a dedicated cable.
[0068] The power supply unit (200) can supply power to the electronic device (100) through the connector (300).
[0069] For example, assume that an electronic device (100) is a device that requires 45W. If the power supply (200) supports a maximum of 25W, it may not be able to supply adequate power to the power supply (200) that requires 45W. To support 45W power, the power supply (200) must increase its internal battery capacity, and there may be a problem that the size increases as the battery capacity increases.
[0070] FIG. 2 is a block diagram illustrating a power supply unit (200) according to one embodiment.
[0071] Referring to FIG. 2, the power supply unit (200) can supply power to an electronic device (100) including a first connection terminal (181).
[0072] The power supply (200) may include a second connection terminal (281). The second connection terminal (281) may include at least one of a first pin (281-1), a second pin (281-2), a third pin (281-3), a fourth pin (281-4), or a fifth pin (281-5).
[0073] The power supply unit (200) may include a second connection terminal (281) comprising a first pin (281-1) for power supply, a second pin (281-2) for identifying whether the connector (300) is connected, a third pin (281-3) for data transmission, a fourth pin (281-4) for data transmission, and a fifth pin (281-5) for ground.
[0074] Each pin is not limited to performing only the stated function and can be used for various predefined functions. The first pin (281-1), second pin (281-2), third pin (281-3), fourth pin (281-4), and fifth pin (281-5) included in the second connection terminal (281) can be used for different purposes prior to supplying power.
[0075] A detailed description of the five pins is provided in FIGS. 9 and FIGS. 10.
[0076] The power supply unit (200) may include a memory (220) for storing instructions.
[0077] The power supply unit (200) may include at least one processor (210) including processing circuitry.
[0078] At least one processor (210) can supply a first voltage to the third pin (281-3) when the connector (300) is connected through the second connection terminal (281). At least one processor (210) can apply a first voltage, which is a test voltage, to the third pin (281-3). After the connector (300) is identified as being connected to the power supply (200), at least one processor (210) can apply a first voltage, which is a test voltage, to the third pin (281-3).
[0079] For example, when the power supply (200) is connected to the connector (300), at least one processor (210) can check whether the electronic device (100) is connected through the connector (300) via a preset pin. The preset pin may be a second pin (281-2). At least one processor (210) can check whether the electronic device (100) is connected to the connector (300) via the second pin (281-2). When the electronic device (100) is connected to the connector (300) and the connector (300) is identified as being connected to the power supply (200), at least one processor (210) can apply a first voltage, which is a test voltage, to the third pin (281-3).
[0080] For example, the power supply (200) can immediately apply a first voltage, which is a test voltage, to the third pin (281-3) when the connector (300) is connected.
[0081] For example, the power supply (200) may include a power button. When user input selecting the power button is received, at least one processor (210) may apply a first voltage, which is a test voltage, to the third pin (281-3).
[0082] At least one processor (210) can obtain a second voltage of the fourth pin (281-4). At least one processor (210) can sense the voltage of the fourth pin (281-4) and obtain the sensed voltage as the second voltage.
[0083] At least one processor (210) can determine a power supply mode based on a first voltage and a second voltage. The power supply mode may indicate the manner in which a power supply unit (200) supplies voltage to an electronic device (100). The power supply mode may be distinguished based on a maximum power value. The power supply mode may include a first mode and a second mode. The maximum power value that can be supplied in the first mode and the maximum power value that can be supplied in the second mode may be different.
[0084] At least one processor (210) can supply power to the electronic device (100) through the first pin (281-1) and the fifth pin (281-5) based on the power supply mode. The first pin (281-1) and the fifth pin (281-5) may be pins to which power is applied. The first pin (281-1) may be a pin to which power is applied. The fifth pin (281-5) may be used as ground.
[0085] At least one processor (210) can identify whether the connector (300) is connected to the second connection terminal (281) through the second pin (281-2). The second pin (281-2) may be a pin for identifying whether there is a connection with the connector (300).
[0086] At least one processor (210) can obtain a first difference value between a first voltage and a second voltage. If the first difference value is greater than or equal to a threshold value, at least one processor (210) can determine the power supply mode as a first mode that supplies maximum first power. At least one processor (210) can supply power based on the first mode. Supplying power may include at least one of an operation of managing power based on a specific mode internally within the power supply unit (200) or an operation of delivering (or supplying) generated power to an external device.
[0087] If the first difference value between the first voltage and the second voltage is greater than or equal to a threshold value, at least one processor (210) can identify that the third pin (281-3) and the fourth pin (281-4) are not short-circuited. If the third pin (281-3) and the fourth pin (281-4) are not short-circuited, at least one processor (210) can determine that the connector (300) is not a pre-configured connector. At least one processor (210) can supply power to the electronic device (100) based on the first mode.
[0088] The first mode may be a mode in which the maximum power value is set to the first power. When the connector (300) is connected, at least one processor (210) can supply power to the electronic device (100) through the connector (300). At least one processor (210) can supply power to the electronic device (100) only up to the maximum first power.
[0089] At least one processor (210) can determine the power supply mode to a second mode that supplies maximum second power if the first difference value is less than a threshold value. At least one processor (210) can supply power based on the second mode.
[0090] For example, the second power can be greater than the first power.
[0091] If the first difference value between the first voltage and the second voltage is less than the threshold value, at least one processor (210) can identify that the third pin (281-3) and the fourth pin (281-4) are short-circuited. If the third pin (281-3) and the fourth pin (281-4) are short-circuited, at least one processor (210) can determine that the connector (300) is a pre-configured connector.
[0092] At least one processor (210) can perform a second mode for high output only when the connector (300) is a pre-configured connector (or dedicated connector). If the connector (300) is not a pre-configured connector (or dedicated connector), at least one processor (210) can perform a first mode for normal output.
[0093] An example of determining a power supply mode by comparing a first voltage and a second voltage is described in FIG. 6.
[0094] At least one processor (210) can perform a voltage comparison operation multiple times. By performing a voltage comparison operation multiple times, the connector (300) can be accurately verified.
[0095] If the first difference value is less than the threshold value, at least one processor (210) can supply a third voltage different from the first voltage to the third pin (281-3). At least one processor (210) can obtain a fourth voltage of the fourth pin (281-4). At least one processor (210) can determine a power supply mode based on the third voltage and the fourth voltage.
[0096] In the description above, it was stated that the third voltage is different from the first voltage. As another example, the third voltage may be the same as the first voltage.
[0097] At least one processor (210) can obtain a second difference value between the third voltage and the fourth voltage.
[0098] If the second difference value is greater than or equal to the threshold value, at least one processor (210) can determine the power supply mode as the first mode. At least one processor (210) can supply power based on the first mode.
[0099] If the second difference value is less than the threshold value, at least one processor (210) can determine the power supply mode to a second mode that supplies maximum second power.
[0100] At least one processor (210) can supply power based on the second mode.
[0101] For example, the second power can be greater than the first power.
[0102] An example of further comparing the third voltage and the fourth voltage is described in FIG. 7.
[0103] At least one processor (210) may additionally use identification information of the electronic device (100) to determine the power supply mode.
[0104] If the second difference value is less than the threshold value, at least one processor (210) can obtain identification information of the electronic device (100) through the second pin (281-2).
[0105] At least one processor (210) can request identification information from the electronic device (100) through the connector (300). At least one processor (210) can transmit a signal requesting identification information of the electronic device (100) through the second pin (281-2) of the second connection terminal (281).
[0106] The electronic device (100) can receive a signal requesting identification information through the second pin (181-2) of the first connection terminal (181). The electronic device (100) can obtain identification information of the electronic device (100) in response to the signal requesting identification information. The electronic device (100) can transmit the identification information of the electronic device (100) to the connector (300) through the second pin (181-2) of the first connection terminal (181).
[0107] The power supply unit (200) can obtain identification information of the electronic device (100) through the second pin (281-2) of the second connection terminal (281) connected to the connector (300).
[0108] At least one processor (210) can compare identification information of an electronic device (100) with multiple identification information previously stored in memory (120). The multiple identification information previously stored may represent a dedicated device stored in advance.
[0109] At least one processor (210) can determine whether the identification information of the electronic device (100) matches one of the multiple identification information stored in memory (220).
[0110] If the identification information of the electronic device (100) does not match one of the multiple identification information stored in the memory (220), at least one processor (210) can determine the power supply mode as the first mode.
[0111] If the identification information of the electronic device (100) matches one of the plurality of identification information stored in the memory (220), at least one processor (210) can determine the power supply mode to a second mode that supplies a maximum second power.
[0112] An example of determining the power supply mode using identification information is described in FIG. 8.
[0113] The first connection terminal (181) and the second connection terminal (281) may be USB (Universal Serial Bus) Type-C terminals. A description related to the USB Type-C terminal is provided in FIG. 15.
[0114] The connection terminals representing the first connection terminal (181) and the second connection terminal (281) may be described as a smart terminal, hub terminal, multi-terminal, double-sided terminal, universal terminal, charging and data transmission terminal, etc.
[0115] For example, the electronic device (100) may be an XR (Extended Reality) device, a VR (Virtual Reality) device, an AR (Augmented Reality) device, or a MR (Mixed Reality) device.
[0116] XR devices, VR devices, AR devices, or MR devices may require different power over time. The power supply (200) must supply power accordingly.
[0117] For example, the electronic device (100) may be a Head-Mounted Display (HMD) device.
[0118] For example, the power supply (200) may include a rechargeable battery. An explanation related to this is described in FIG. 4.
[0119] For the embodiments described above, it has been stated that the power supply unit (200) determines the power supply mode. For the embodiments, the electronic device (100) may determine the power supply mode. An embodiment related to this is described in FIG. 18. The description of the remaining drawings may be applied in the same way to the operations described in FIG. 18.
[0120] When a preset electronic device (100) is identified through a test voltage, the power supply (200) can supply power in a second mode, which is a high-output mode. Appropriate power can be supplied to the electronic device (100) that requires high output.
[0121] The power supply (200) can determine the type of electronic device (100) connected to the connector (300) by applying a test voltage to the second connection terminal (281). Since high-output power is provided only when a pre-set device is connected, heat generation can be effectively controlled. Through effective heat generation control, the power supply (200) can stably supply power and prevent overheating.

[0259] If the display is composed of one of a liquid crystal display, a digital mirror display, or a silicon liquid crystal display, the electronic device may include a light source that irradiates light onto the screen output area of the display.
[0260] In another embodiment, where the display can generate light on its own, for example, by being composed of one of an organic light-emitting diode or a micro LED, the electronic device can provide a virtual image of good quality to the user without including a separate light source.
[0261] In one embodiment, if the display is implemented with an organic light-emitting diode or a micro LED, a light source is unnecessary, so the electronic device can be made lighter.
[0262] The electronic device may include a display, a first transparent member and / or a second transparent member, and the user may use the electronic device while wearing it on their face.

[0269] A light waveguide can guide display light emitted from a light source to the user's eye by using at least one diffraction element or reflection element included in the light waveguide.
[0270] According to one embodiment, the diffraction element may include an input optical member / an output optical member (not shown). For example, the input optical member may refer to an input grating area, and the output optical member (not shown) may refer to an output grating area.
[0271] The input grating area can serve as an input terminal that diffracts (or reflects) light output from (e.g., Micro LED) to transmit light to a transparent member of the screen display (e.g., first transparent member, second transparent member). The output grating area can serve as an output terminal that diffracts (or reflects) the light transmitted to the transparent member of the waveguide (e.g., first transparent member, second transparent member) to the user's eye.
[0272] According to one embodiment, the reflection element may include a total internal reflection optical element or a total internal reflection waveguide for total internal reflection (TIR). For example, total internal reflection is a method of inducing light, which may mean creating an angle of incidence such that light (e.g., a virtual image) input through an input grating area is 100% reflected from one side (e.g., a specific side) of the waveguide and is transmitted 100% to an output grating area.
[0273] In one embodiment, light emitted from a display may have its light path guided to a waveguide through an input optical member. Light traveling inside the waveguide may be guided toward the user's eye through an output optical member. A screen display may be determined based on the light emitted toward the eye.

[0276] The light output unit may include an LED. The light output unit may include an IR LED of an infrared wavelength.
[0277] For example, the light output unit can be attached adjacent to a camera mounted near the hinge connecting the frame and the temple, or near the bridge connecting the frames. The light output unit can be used as a means to supplement ambient brightness during camera shooting. The light output unit can be utilized when subject detection is difficult in dark environments.
[0278] The electronic device (100) may include at least one of a printed circuit board (PCB), a microphone, a speaker, a battery, an antenna, and a sensor (an accelerometer, a gyroscope, a touch sensor).

[0283] For example, when the connector (300) is connected to the second connection terminal (281), two of the 24 pins (RX1+, RX1-) described in the embodiment (1500) of FIG. 15 may be short-circuited.
