Abstract
Description
Technical Field
[0001] This disclosure relates to electronic devices including wireless charging structures. Background Technology
[0002] Electronic devices can output information stored within them as sound or images. With the increasing integration of electronic devices and the widespread adoption of ultra-high-speed and high-capacity wireless communication, a wide variety of functions are now offered in single electronic devices (such as mobile communication terminals). For example, in addition to communication functions, various functions such as entertainment (e.g., gaming), multimedia (e.g., music / video playback), communication and security functions for mobile banking, schedule management, and e-wallet functions are integrated into a single electronic device.
[0003] Furthermore, in an information-based society, the importance of sensors and power supply embedded in electronic devices is increasingly emphasized in order to enable information and communication devices to operate and connect with each other regardless of time or location. Typically, due to the rapid diversification of mobile devices such as mobile phones, charging the batteries of these devices requires time and effort from the user. Wireless power transfer technology has recently gained attention as a solution to this problem. For example, wireless power receiving devices (such as mobile devices that receive energy wirelessly) can be driven by the received wireless power, or can be driven using the power from charging their batteries using the received wireless power.
[0004] Wireless power transfer technology (also known as wireless power delivery or wireless energy transfer) is a technology that uses the principle of magnetic field induction to wirelessly transfer electrical energy from a transmitter to a receiver. Wireless energy transfer schemes can generally be divided into magnetic induction schemes, electromagnetic resonance schemes, and power transfer schemes using short-wavelength radio frequency.
[0005] The above information is provided solely to aid in understanding the background of this disclosure. Furthermore, no determination or assertion is made regarding whether any of the information described above is applicable to prior art relative to this disclosure. Summary of the Invention
[0006] Typically, a wireless charging structure for wireless charging can be configured to face the rear side of the electronic device (e.g., the side opposite to where the display is located). However, there is a need for a wireless charging structure embedded in the electronic device that includes both receiving (RX) and transmitting (TX) functions, or a wireless charging structure that provides charging functionality toward the display direction in an electronic device including a foldable display.
[0007] Because the wireless charging structure, which provides charging functionality towards the display direction, is provided in the structure of the display, wireless charging structure, and conductive layer stacked sequentially, it is difficult to extract the connection structure of the flexible printed circuit board (FPCB) of the wireless charging structure. Furthermore, due to the increased length, the DC resistance component may increase, which may cause surface heat generation or reduce charging efficiency.
[0008] Due to variations in the size and arrangement of wireless charging structures, additional height compensation structures may be required, resulting in lower manufacturability and increased material costs.
[0009] The electronic device according to this disclosure can improve the stacked structure, simplify the structure, and provide the effect of reducing material costs by setting a wireless charging structure in the display component to provide RX and TX functions.
[0010] However, the problems to be solved in this disclosure are not limited to those described above, and can be extended in various ways without departing from the spirit and scope of this disclosure.

[0040] Figure 1 This is a block diagram illustrating an electronic device 101 in a network environment 100 according to various embodiments. (Refer to...) Figure 1In network environment 100, electronic device 101 can communicate with electronic device 102 via a first network 198 (e.g., a short-range wireless communication network), or with electronic device 104 or server 108 via a second network 199 (e.g., a long-range wireless communication network). According to an embodiment, electronic device 101 can communicate with electronic device 104 via server 108. According to an embodiment, electronic device 101 may include a processor 120, memory 130, input device 150, sound output device 155, display device 160, audio module 170, sensor module 176, interface 177, haptic module 179, camera module 180, power management module 188, battery 189, communication module 190, subscriber identification module (SIM) 196, or antenna module 197.

Additionally or alternatively, auxiliary processor 123 may be adapted to consume less power than main processor 121, or adapted for a specific function. The auxiliary processor 123 can be implemented separately from the main processor 121, or it can be implemented as part of the main processor 121.
[0042] When the main processor 121 is inactive (e.g., in sleep mode), the auxiliary processor 123 may control at least some of the functions or states associated with at least one component of the electronic device 101 (other than the main processor 121) (e.g., display device 160, sensor module 176, or communication module 190).

According to an embodiment, display device 160 may include touch circuitry adapted to detect touch or sensor circuitry (e.g., a pressure sensor) adapted to measure the intensity of the force caused by touch.
[0048] The audio module 170 can convert sound into electrical signals and vice versa. According to an embodiment, the audio module 170 can obtain sound via the input device 150, or output sound via the sound output device 155 or headphones of an external electronic device (e.g., electronic device 102) that is directly (e.g., wired) or wirelessly connected to the electronic device 101.
[0049] Sensor module 176 can detect the operating state of electronic device 101 (e.g., power or temperature) or the environmental state outside electronic device 101 (e.g., user state), and then generate an electrical signal or data value corresponding to the detected state. According to embodiments, sensor module 176 may include, for example, a gesture sensor, gyroscope sensor, atmospheric pressure sensor, magnetic sensor, accelerometer, grip sensor, proximity sensor, color sensor, infrared (IR) sensor, biometric sensor, temperature sensor, humidity sensor, or illuminance sensor.
[0050] Interface 177 may support one or more specific protocols used to enable direct (e.g., wired) or wireless connection between electronic device 101 and external electronic device (e.g., electronic device 102). Depending on the implementation, interface 177 may include, for example, a High Definition Multimedia Interface (HDMI), a Universal Serial Bus (USB) interface, a Secure Digital Card (SD) interface, or an audio interface.
[0051] Connection end 178 may include a connector, through which electronic device 101 can be physically connected to an external electronic device (e.g., electronic device 102). According to embodiments, connection end 178 may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).
[0052] The tactile module 179 can convert electrical signals into mechanical stimulation (e.g., vibration or motion) or electrical stimulation that can be recognized by a user through his touch or kinesthesia. According to embodiments, the tactile module 179 may include, for example, a motor, a piezoelectric element, or an electrical stimulator.
[0053] Camera module 180 can capture still or moving images. Depending on the implementation, camera module 180 may include one or more lenses, an image sensor, an image signal processor, or a flash.
[0054] The power management module 188 manages the power supply to the electronic device 101. According to embodiments, the power management module 188 may be implemented as at least a portion of, for example, a power management integrated circuit (PMIC).
[0055] Battery 189 can power at least one component of electronic device 101. According to embodiments, battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable rechargeable battery, or a fuel cell.
[0056] Communication module 190 can support the establishment of a direct (e.g., wired) or wireless communication channel between electronic device 101 and external electronic devices (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor (AP)) and support direct (e.g., wired) or wireless communication. According to embodiments, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). One of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a cellular network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components (e.g., multiple chips) that are separate from each other. The wireless communication module 192 can identify and verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199) using user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.
[0057] Antenna module 197 can transmit or receive signals or power to or from the outside of electronic device 101 (e.g., external electronic device). According to an embodiment, antenna module 197 may include an antenna comprising a radiating element formed of a conductive material or conductive pattern formed in or on a substrate (e.g., a PCB). According to an embodiment, antenna module 197 may include multiple antennas. In this case, at least one antenna suitable for a communication scheme used in a communication network (such as a first network 198 or a second network 199) can be selected from the multiple antennas by, for example, communication module 190 (e.g., wireless communication module 192). Signals or power can then be transmitted or received between communication module 190 and external electronic device via the selected at least one antenna. According to an embodiment, additional components besides the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may be additionally incorporated into antenna module 197.
[0058] At least some of the aforementioned components can be interconnected and communicate signals (e.g., commands or data) between them via an inter-peripheral communication scheme (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).
[0059] According to an embodiment, commands or data can be sent or received between electronic device 101 and external electronic device 104 via server 108 connected to the second network 199. Each of electronic device 102 and electronic device 104 can be a device of the same type as electronic device 101, or a device of a different type. According to an embodiment, all or some operations that would be performed on electronic device 101 can be performed on one or more of external electronic devices 102, external electronic devices 104, or server 108. For example, if electronic device 101 is required to automatically perform a function or service, or is required to perform a function or service in response to a request from a user or another device, electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service, instead of running the function or service, or electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service in addition to running the function or service. Upon receiving the request, the one or more external electronic devices may perform at least a portion of the requested function or service, or perform additional functions or services related to the request, and transmit the result of the execution to electronic device 101. Electronic device 101 may provide the result as at least a partial response to the request, either with further processing or without further processing. For this purpose, technologies such as cloud computing, distributed computing, or client-server computing may be used.

[0086] Figure 5 This is a block diagram of a wireless charging system according to an embodiment of the present disclosure.
[0087] Reference Figure 5 The wireless charging system according to the embodiments may include an external electronic device 10 configured to transmit wireless power and a wireless power transmitting / receiving device 101 configured to receive wireless power transmitted from the external electronic device 10 (e.g., Figure 1 (Electronic device 101 in the middle).
[0088] The external electronic device 10 according to the embodiment may include a circuit board comprising various circuit units. The circuit board may include a power transmission / reception circuit 411, a control circuit 412, a communication circuit 413, a sensing circuit 415, and a storage circuit 416. The wireless power transmission / reception device 101 may include a power transmission / reception circuit 451, a control circuit 452, a communication circuit 453, a sensing circuit 454, and a display 455.
[0089] According to various embodiments of this disclosure, the power transmitting / receiving circuit 411 can provide the power required for the wireless power transmitting / receiving device 101 to receive power, and may include a loop coil 411L formed of a conductive pattern. The power transmitting / receiving circuit 411 may be configured to wirelessly transmit power to the wireless power transmitting / receiving device 101 via the loop coil 411L. Here, the power transmitting / receiving circuit 411 can receive power in the form of a DC or AC signal from an external source (e.g., a power input), and can provide the received power to the wireless power transmitting / receiving device 101 in the form of an AC signal. For example, when receiving power provided in the form of a DC signal from an external source, the power transmitting / receiving circuit 411 can use a power inverter to convert the power in the form of a DC signal into an AC signal, and can provide the power to the wireless power transmitting / receiving device 101 in the form of an AC signal. As another example, when receiving power wirelessly provided from an external source, the power transmitting / receiving circuit 411 can use a rectifier to rectify the power in the form of an AC signal into a DC signal. The rectified power can be transmitted to a charger or PMIC to charge a battery.
[0090] According to various embodiments of this disclosure, the power transmitting / receiving circuit 411 can provide an AC signal as a frequency resonant signal to the wireless power transmitting / receiving device 101. The power transmitting / receiving circuit 411 may include a loop coil 411L formed of a conductive pattern, and can transmit or receive a predetermined frequency resonant signal generated when current is applied to the loop coil 411L using an electromagnetic induction scheme or a resonant scheme. The power transmitting / receiving circuit 411 may also include a first communication circuit 413a (e.g., a resonant circuit), and can perform communication (e.g., data communication) in an in-band format using the frequency resonant signal generated by the loop coil 411L. The first communication circuit 413a in the communication circuit 413 will be described in more detail later. When the power transmitting / receiving circuit 411 is implemented as a resonant circuit, the inductance L of the loop coil 411L of the resonant circuit may be variable.
[0091] Furthermore, the power transmitting / receiving circuit 411 can be implemented as a power receiving interface that receives power from the outside and provides that power to other components. In addition to the toroidal coil 411L, the power transmitting / receiving circuit 411 may also include, for example, a power adapter 411a, a power generation circuit 411b, and a matching circuit 411c.
[0092] According to various embodiments of this disclosure, the power adapter 411a can receive AC or DC power input from an external source, or it can receive power signals from a battery device, and can output a DC signal with a predetermined voltage value. The voltage value of the DC signal output from the power adapter 411a can be controlled by the control circuit 412. The DC signal output from the power adapter 411a can be output to the power generation circuit 411b.
[0093] According to various embodiments of this disclosure, the power generation circuit 411b can convert a DC signal output from the power adapter 411a into an AC signal and can output an AC signal. The power generation circuit 411b may include a predetermined amplifier (not shown). When the DC signal input through the power adapter 411a is lower than a predetermined strength, the power generation circuit 411b can use the amplifier to amplify the DC signal to the predetermined strength. Furthermore, the power generation circuit 411b may also include circuitry for converting the DC signal input from the power adapter 411a into an AC signal based on a control signal input from the control circuit 412. For example, the power generation circuit 411b can use a predetermined inverter to convert the DC signal into an AC signal. Alternatively, the power generation circuit 411b may further include a gate driving device (not shown), which can convert the DC signal into an AC signal and control the DC signal by switching it on / off.
[0094] According to various embodiments of this disclosure, the matching circuit 411c can perform impedance control operations. For example, when an AC signal output from the power generation circuit 411b is transmitted to the loop coil 411L, an electromagnetic field can be formed in the loop coil 411L by the AC signal. At this time, the matching circuit 411c can adjust the frequency band of the received electromagnetic field signal by impedance adjustment. Through this adjustment, the matching circuit 411c can adjust, for example, the impedance seen by the matching circuit 411c from the wireless power transmitting / receiving device 101 transmitted through the loop coil 411L, in order to perform control such that the output signal power becomes high output. The matching circuit 411c can adjust the impedance based on the control of the control circuit 412. The matching circuit 411c may include at least one of an inductor (e.g., a coil), a capacitor, and a switching device. The control circuit 412 can control the connection state of at least one of the inductor and the capacitor by the switching device, thereby causing the matching circuit 411c to perform an impedance changing operation.
[0095] Those skilled in the art will readily understand that the power transmitting / receiving circuit 411 is not limited thereto, and may include any means capable of transmitting and receiving electromagnetic waves.
[0096] According to various embodiments of this disclosure, the sensing circuit 415 can sense changes in the amount of power to be transmitted to the wireless power transmitting / receiving device 101. In the external electronic device 10, the amount of transmission power to be transmitted to the wireless power transmitting / receiving device 101 can be generated in response to the amplitude of the current / voltage applied to the loop coil 411L, and the sensing circuit 415 can sense the amount of transmission power. For example, in the electronic device 10, the amount of power to be transmitted can vary according to changes in the current / voltage of the signal output through the loop coil 411L. For example, as the amplitude of the current / voltage applied to the loop coil 411L increases, the amount of transmission power to be transmitted can increase, and as the amplitude of the current / voltage applied to the loop coil 411L decreases, the amount of transmission power to be transmitted can decrease.
[0097] According to embodiments of this disclosure, sensing circuit 415 (e.g., a temperature sensor (thermometer)) can sense temperature changes in external electronic device 10. Sensing circuit 415 can generate power to be transmitted by power transmitting / receiving circuit 411, or it can sense temperature changes caused by heat, which may be generated by electronic device 10 during the transmission of generated power to wireless power transmitting / receiving device 101. For example, sensing circuit 415 can measure at least one of the internal temperature and the external temperature of external electronic device 10. According to embodiments of this disclosure, sensing circuit 415 may include at least one of a current sensor, a voltage sensor, and a temperature sensor. The current sensor can be implemented, for example, a charge counter (e.g., a coulomb counter), but there are no limitations on the implementation. The voltage sensor is not limited in type, as long as it is a voltmeter capable of measuring the voltage of wireless power transmitting / receiving device 101.
[0098] According to various embodiments of this disclosure, the control circuit 412 can control the overall operation of the external electronic device 10. The control circuit 412 can use algorithms, programs, or applications required for control and stored in the storage circuit 416 to control the overall operation of the external electronic device 10. Furthermore, the control circuit 412 can perform control to wirelessly transmit power to the wireless power transmitting / receiving device 101 via the power transmitting / receiving circuit 411. The control circuit 412 can also perform control to wirelessly receive information from the wireless power transmitting / receiving device 101 via the communication circuit 413.
[0099] According to various embodiments of this disclosure, the communication circuits (first communication circuit 413a and second communication circuit 413b) (for example) Figure 1 The interface 177 and communication module 190 can communicate with the wireless power transmitter / receiver 101 in a predetermined manner. The communication circuit 413 can communicate data with the communication circuit 453 of the wireless power transmitter / receiver 101.
[0100] Simultaneously, the communication circuit 413 can transmit signals for information about the external electronic device 10 to the wireless power transmitter / receiver 101. Here, the communication circuit 413 can transmit unicast, multicast, or broadcast signals. Furthermore, the communication circuit 413 can transmit charging function control signals to control the charging function of the wireless power transmitter / receiver 101. The charging function control signal can be a control signal that controls the power transmitter / receiver circuit 451 of a specific electronic device (e.g., the wireless power transmitter / receiver 101) to enable or disable the charging function.
[0101] Meanwhile, the communication circuit 413 can receive signals from other wireless power transmitting / receiving devices (not shown) and wireless power transmitting / receiving device 101 or transmit signals to other wireless power transmitting / receiving devices (not shown) and wireless power transmitting / receiving device 101.
[0102] The communication circuit 413 according to the embodiment may include at least one of, for example, a first communication circuit 413a and a second communication circuit 413b, wherein the first communication circuit 413a is implemented as hardware having a power transmission / reception circuit 411 to allow the external electronic device 10 to perform communication in an in-band format, and the second communication circuit 413b is implemented as hardware different from the power transmission / reception circuit 411 to allow the external electronic device 10 to perform communication in an out-of-band format.
[0103] For example, when the communication circuit 413 includes a first communication circuit 413a capable of performing communication in an in-band format, the first communication circuit 413a can receive an electromagnetic field signal with a predetermined frequency and signal level through the loop coil 411L of the power transmission / reception circuit 411. In this case, the control circuit 412 can extract the information received from the wireless power transmission / reception device 101 by decoding the electromagnetic signal with the predetermined frequency and signal level. Furthermore, the first communication circuit 413a can apply a signal for information to be transmitted to the loop coil 411L of the power transmission / reception circuit 411. For example, the first communication circuit 413a can add a signal for the information to be transmitted to the signal output from the matching circuit 411c. In this case, the control circuit 412 can perform control such that the connection state of at least one of the inductor and capacitor of the matching circuit 411c is controlled by the on / off control of the switching device included in the matching circuit 411c. For example, the control circuit 412 can perform on / off keying coding. The power amplitude (e.g., the voltage at the output terminal of the rectifier) output by the loop coil 451L of the wireless power transmitter / receiver 101 can vary in response to on / off control, and the wireless power transmitter / receiver 101 can decode it in an on / off controlled manner to obtain information.
[0104] For example, when the communication circuit 413 includes a second communication circuit 413b capable of performing communication in an out-of-band format, the second communication circuit 413b can communicate with the communication circuit 453 (e.g., the first communication circuit 453a and the second communication circuit 453b) of the wireless power transmitting / receiving device 101 using near field communication (NFC), ZigBee communication, infrared communication, visible light communication, Bluetooth Low Energy (BLE) communication, etc.
[0105] Meanwhile, the above-described communication scheme of communication circuit 413 is merely an example, and the implementation methods disclosed herein are not limited to the specific communication scheme performed by communication circuit 413.
[0106] In addition, the communication circuit 413 can transmit a charging function control signal for controlling the charging function of the wireless power transmitting / receiving device 101. The charging function control signal can be a control signal that controls the power transmitting / receiving circuit 451 of the wireless power transmitting / receiving device 101 to enable or disable the charging function.
[0107] The communication circuit 413 can receive signals not only from the wireless power transmitter / receiver 101, but also from other wireless power transmitters (not shown). For example, the communication circuit 413 can be configured as hardware different from the power transmitter / receiver circuit 411, and thus the external electronic device 10 can perform communication in an out-of-band format. However, this is only an example. The power transmitter / receiver circuit 411 and the communication circuit 413 can be implemented as a single piece of hardware, so the external electronic device 10 can perform communication in an in-band format.
[0108] External electronic device 10 and wireless power transmitter / receiver 101 can transmit / receive various signals through their respective communication circuits 413 and 453.
[0109] Furthermore, according to various embodiments of this disclosure, the electronic device 10 may be a portable terminal including a power transmission / reception circuit 411 and a battery. Therefore, the external electronic device 10, as a portable terminal, can transmit the power stored in the battery as wireless power to the wireless power transmission / reception device 101. Furthermore, according to various embodiments of this disclosure, the external electronic device 10 is not limited to a wireless charger or a portable terminal, and may be various electronic devices including the power transmission / reception circuit 411.
[0110] Simultaneously, the power transmission / reception circuit 451 of the wireless power transmission / reception device 101 according to the embodiment can receive power from the power transmission / reception circuit 411 of the external electronic device 10. The power transmission / reception circuit 451 can be implemented in the form of a power receiving interface to receive power from the outside. The power transmission / reception circuit 451 may include a loop coil 451L made of a conductive pattern. The power transmission / reception circuit 451 can receive wireless power in the form of electromagnetic waves generated in response to the current / voltage applied to the loop coil 411L of the power transmission / reception circuit 411 of the external electronic device 10 via the loop coil 451L. For example, the power transmission / reception circuit 451 can receive from the power transmission / reception circuit 411 of the external electronic device 10: power provided to the loop coil 451L of the adjacent power transmission / reception circuit 451 by generating an induced electromotive force in the form of an AC waveform from the power applied to the loop coil 411L of the power transmission / reception circuit 411. For example, the power transmitting / receiving circuit 451 can receive wireless signal power in the form of electromagnetic waves generated in response to the current / voltage applied to the loop coil 411L of the power transmitting / receiving circuit 411 of the external electronic device 10 via the loop coil 451L.
[0111] In addition to the toroidal coil 451L, the power transmitting / receiving circuit 451 may also include, for example, a matching circuit 451a, a rectifier circuit 451b, a regulating circuit (regulator) 451c, a switching circuit 451d, and a battery 451e.
[0112] Matching circuit 451a can perform impedance control operations. For example, signal power transmitted through the loop coil 411L of external electronic device 10 can be transmitted to loop coil 451L to form an electromagnetic field. In this case, matching circuit 451a can adjust the frequency band of the formed electromagnetic field signal to adjust the impedance observed from matching circuit 451a. Through this adjustment, matching circuit 451a can perform control such that the input power received from external electronic device 10 through loop coil 451L is improved in terms of efficiency and output. Matching circuit 451a can adjust impedance based on control of control circuit 452. Matching circuit 451a may include at least one of an inductor (e.g., a coil), a capacitor, and a switching device. Control circuit 452 can perform impedance control operations by controlling the connection state with at least one of the inductor and capacitor via the switching device.
[0113] The rectifier circuit 451b can rectify the power of the wireless signal, which is a DC signal, received by the loop coil 451L, and can be implemented, for example, in the form of a rectifier circuit including a bridge diode.
[0114] The regulating circuit 451c can convert the strength of the rectified signal to a predetermined strength. The regulating circuit 451c may include a predetermined DC / DC converter (not shown) (e.g., a buck converter). For example, the regulating circuit 451c can convert rectified power so that the output voltage becomes 5V. Simultaneously, applicable minimum and maximum values of the voltage can be preset in the preceding stage of the regulating circuit 451c.
[0115] The switching circuit 451d can connect the regulating circuit 451c and the battery 451e. The switching circuit 451d can be kept on / off under the control of the control circuit 452.
[0116] When the switching circuit 451d is in the ON state, the battery 451e can be charged using the power provided by the regulating circuit 451c.
[0117] The sensing circuit 454 can sense changes in the charging state of the wireless power transmitter / receiver 101. For example, the sensing circuit 454 can use a predetermined current / voltage sensor 454a to periodically or non-periodically measure the current / voltage value of the signal received by the loop coil 451L. The wireless power transmitter / receiver 101 can calculate the amount of power received by the wireless power transmitter / receiver 101 based on the measured current / voltage.
[0118] The sensing circuit 454 can sense changes in the charging environment of the wireless power transmitter / receiver 101. For example, the sensing circuit 454 can use a predetermined temperature sensor 454b to periodically or non-periodically measure at least one of the internal and external temperatures of the wireless power transmitter / receiver 101. The sensing circuit 454 can use a predetermined illuminance sensor 454c to periodically or non-periodically measure the illuminance (brightness) around the wireless power transmitter / receiver 101. The sensing circuit 454 can use a predetermined sound sensor 454d to periodically or non-periodically measure the sound (noise) level around the wireless power transmitter / receiver 101.

Figure 4 The front panel 320, rear panel 380, display 330, side frame structure 331 and first support member 332 (e.g. bracket) have the same structure.
[0123] According to various embodiments of this disclosure, the front panel 320 may be configured to face a first direction (+Z), and the rear panel 380 may be configured to face a second direction (-Z) opposite to the first direction (+Z).

Below the active region, an opaque, non-conductive material may be applied, making internal electronic components, signal lines, or circuit lines invisible from the outside.
[0124] According to various embodiments of this disclosure, the bracket 520 may be disposed between the rear panel 380 and the display assembly 510, and at least a portion of its side may form a first antenna 551 or a second antenna 552. For example, the rear end portion of the bracket 520 may form the first antenna 551, and the front end portion of the bracket 520 may form the second antenna 552.
[0125] According to various embodiments of this disclosure, the display assembly 510 may include a display panel 511 and a flexible printed circuit board 512. The display panel 511 is stacked with a front panel 320 and includes one or more display pixels and a substrate electrically connected to the one or more display pixels. The flexible printed circuit board 512 extends from the display panel 511 and is at least partially bent. As another example, the display assembly 510 may include an optical layer 513 and a dielectric layer 514 disposed on the display panel 511 in a first direction (+Z).

As another example, the display assembly 510 may include a digitizer panel configured to detect a magnetic field type stylus.
[0126] According to various embodiments of this disclosure, the display panel (e.g., an active organic light-emitting diode) 511 is visible to the outside through a transparent front panel 320 and may include a display element layer and a TFT layer connected to the display element layer, the display element layer including one or more pixels. According to embodiments of this disclosure, optical components and / or a touch panel may be mounted between the front panel 320 and the display element layer or inside the display element layer. For example, the flexible display 511 may be an output device configured to output images and may also be used as an input device with touchscreen functionality. When the display panel 511 has touchscreen functionality, the display panel may correspond to an indium tin oxide (ITO) film or a touch sensor panel for sensing the user's touch position, etc. As another example, a dielectric layer (not shown) may be disposed between the display element layer and the touch sensor panel.
[0127] According to various embodiments of this disclosure, an optical layer 513 disposed on one surface of a display panel 511 or disposed within the display panel 511 can transmit light from a screen output from the display panel 511. For example, the optical layer 513 may include an optical compensation film for correcting phase differences, etc., in the screen output from the display element layer. The optical layer 513 may include an optical compensation film (e.g., a polarizing film). In the optical compensation film, a triacetyl cellulose (TAC) film is attached to opposite sides of a polyvinyl alcohol (PVA) film that provides polarization functionality, and the surface-side TAC film may be protected by a surface coating.
[0128] According to various embodiments of this disclosure, a dielectric layer 514 may be provided between the front panel 320 and the display panel 511. The dielectric layer 514 may be configured to contact the front panel 320 and may comprise, for example, silicon, air, foam, film, optically clear adhesive (OCA), rubber, ink, or polymer (PC or PET). The dielectric layer 514 may be configured to attach to the front panel 320 and / or the optical layer 513, or may have a refractive index different from that of the front panel 320 and / or the optical layer 513.
[0129] According to various embodiments of this disclosure, multiple layers may be disposed below the display panel 511 (e.g., in a second direction (-Z)). For example, a polymer layer 516, a light-shielding member, and / or a heat dissipation layer may be disposed sequentially. The light-shielding member may be configured as a layer that shields the back side of the display panel 511. The light-shielding layer may be, for example, an embossed member 517, a padding member 518, or a copper (Cu) sheet, and may include black. As another example, the heat dissipation layer may block heat generated from the display panel 511, or may block heat generated by electronic components (e.g., wireless communication circuitry mounted on a main printed circuit board) from being transferred to the display panel 511.
[0130] According to various embodiments of this disclosure, the flexible printed circuit board 512 of the display assembly 510 may be electrically connected to the display panel 511, and may include a first region 512a electrically connected to the display panel 511 and at least partially bent, and a second region 512b extending from the first region 512a and disposed between the bracket 520 and the display panel 511. For example, the second region 512b may be configured as an active region facing the front panel 320, and the first region 512a may be configured as a non-active region facing the front panel 320.
[0131] According to embodiments of this disclosure, the flexible printed circuit board 512 may include a first connector 512c and a second connector 512d disposed spaced apart from each other. For example, the first connector 512c disposed at one end of a first region 512a of the flexible printed circuit board 512 may be directly connected to the display panel 511 of the display assembly 510, and the second connector 512d disposed in a second region 512b may be electrically connected to the main printed circuit board 340.
[0132] According to embodiments of this disclosure, a wiring layer (not shown) extending from the display panel 511 can be disposed on a flexible printed circuit board 512. For example, wiring for a display, touch sensor, fingerprint sensor, pressure sensor, optical sensor, or EMR sensor can be disposed on the flexible printed circuit board 512. As another example, the flexible printed circuit board 512 may include display driver circuitry (display driver IC) and / or touch sensor panel IC (TSP-IC). The wiring layer may include a chip-on-film or tape-on-a-carrier package having a flexible printed circuit film or driver chip. The wiring layer can be connected via connectors to a printed circuit board on which control circuitry is formed (e.g., Figure 4 Printed circuit board 340 in the circuit board). The display driver circuit is electrically connected to the circuit board (e.g., Figure 4The printed circuit board 340) has a control circuit, and the control circuit is interconnected with the display driver circuit to receive and process image data or image information, wherein the image information includes image control signals corresponding to commands for controlling the image data so as to allow visual information (e.g., text, images, or icons) to be displayed through the display panel 511.
[0133] According to embodiments of the present disclosure, a first region 512a of the flexible printed circuit board 512 may extend from the rear end of the display panel 511 and may be bent toward the rear plate 380 (e.g., in a second direction (-Z)) to connect to the second region 512b. The second region 512b of the flexible printed circuit board 512 is substantially plate-shaped, and the length of the second region 512b may extend substantially from the rear end portion of the electronic device 101 to the central region of the electronic device 101.
[0134] According to embodiments of this disclosure, a portion of the second region 512b may include a coil region 610, in which a wireless charging structure 530 may be disposed. For example, the coil region 610, in which the wireless charging structure 530 is disposed, may be positioned facing the central region of the electronic device 101. As another example, the coil region 610, in which the wireless charging structure 530 is disposed, may include a recessed shape. The coil region 610 may be configured to correspond to the shape of the wireless charging structure. For example, the coil region may have a recessed or open shape in which a wireless charging structure 530, including a circular coil, may be inserted. As another example, the coil region 610, in which the wireless charging structure 530 is disposed, may be integrally configured by being disposed in at least some or all of the layers of a flexible printed circuit board formed of multiple conductive layers. Therefore, when viewed in cross-section from the second region 512b of the flexible printed circuit board 512, the wireless charging structure 530 substantially does not protrude above or below the second region 512b. Since no operation occurs, additional height compensation structures can be excluded.
[0135] According to embodiments of this disclosure, the second region 512b may extend to the front end (e.g., in the +X direction) or rear end (e.g., in the -X direction) of the electronic device 101. In the second region 512b, the area other than the coil region 610 and / or the wiring region where wiring or electronic components are arranged may be configured as a shielding region 620. The shielding region 620 may be formed in the region facing the first antenna 551 to prevent the TX power or baseband noise of the first antenna 551 from flowing into the sensors (e.g., touch sensors or digitizers) of the display panel 511, thereby suppressing sensor malfunctions. As another example, the shielding region 620 may be disposed in the rear end portion of the second region 512b, and a separate shielding member 630 for preventing electromagnetic waves from the second antenna 552 from flowing into the second region 552 may be disposed in the front end portion of the electronic device 101 instead of the second region 512b. The shielding member 630 may be coplanar with the flexible printed circuit board 512 and may comprise the same material as the shielding material (e.g., copper) of the shielding region 620.
[0136] According to various embodiments of this disclosure, the wireless charging structure 530 of the electronic device 101 may include at least one coil and may be disposed in the coil region 610 of the flexible printed circuit board 512. The wireless charging structure 530 disposed in at least one region of the coil region 610 may have a flat surface overall.
[0137] According to embodiments of this disclosure, a wireless charging structure 530 may be disposed between a front panel 320 and a bracket 520. The wireless charging structure 530 may include: a coil portion 531 including at least one coil; a transmission line 532 extending from the coil portion 531 to connect to a main printed circuit board; and a core 533 formed to surround at least a portion of the coil portion 531 and the transmission line 532. For example, at least a portion of the core 533 may have an opening shape formed within a second region 512b, and the coil portion 531 and the transmission line may be inserted into the core 533. Furthermore, the wireless charging structure 530 may include control circuitry configured to wirelessly transmit power using the coil portion 531.
[0138] According to embodiments of the present disclosure, coil portion 531 may include at least one coil, and the at least one coil may be formed as a layer wound with a predetermined first number of turns into a predetermined first shape. For example, a coil may be wound in the same direction to provide current in the same direction. The coil may be arranged with an opening at its internal center, and lines extending from its inner diameter end and / or outer diameter end (e.g., power transmission line 532) may be electrically connected to the main printed circuit board 340. As another example, at least one coil may be arranged such that multiple layers can be stacked on corresponding conductive layers of the flexible printed circuit board 512 and electrically connected through vias. As another example, coil portion 531 may include multiple coils, and the respective coils may be implemented with different numbers of turns and different shapes. According to embodiments of the present disclosure, at least one coil of coil portion 531 may be a coil conforming to the WPC standard. As another example, a ferrite composite sheet for concentrating magnetic flux may be attached to the center of coil portion 531, and the composite sheet may be formed in a circular shape to correspond to the shape of coil portion 531.
[0139] According to embodiments of this disclosure, transmission line 532 is a conductor extending from at least one coil, and components for electrical connection to the main printed circuit board 340 (e.g., coaxial cable connectors, board-to-board (B-to-B) connectors, C-clamps, or short pads) may be provided at each end of transmission line 532. For example, transmission line 532 extending from one coil may be connected to a source of the main printed circuit board 340 to provide a terminal capable of receiving power.
[0140] According to embodiments of this disclosure, the core 533 can provide space for forming a magnetic circuit, which is the path through which the magnetic flux induced by the internal electrodes when a current is applied to the internal electrodes via the transmission line 532. The core 533 can be formed of a ceramic material, a ferrite material, or a combination thereof having high permeability. As another example, the core 533 may include a metal alloy material. However, the core 533 is not limited thereto and can be changed or modified as long as it is capable of forming a magnetic circuit in response to a current applied from the transmission line 532 and is made of a material having high permeability.
[0141] According to embodiments of this disclosure, the wireless charging structure 530 can be disposed on the flexible printed circuit board 512 and oriented toward the front panel 320. When the coil region of the flexible printed circuit board 512 is formed with an opening toward the front panel 320, one side of the wireless charging structure 530 disposed in the coil region can directly face the display assembly 510. However, the arrangement of the wireless charging structure 530 is not limited thereto. When the coil region of the flexible printed circuit board 512 opens toward the rear panel 380, one side of the wireless charging structure 530 disposed in the coil region can directly face the magnetic plate 540.
[0142] According to embodiments of this disclosure, multiple wireless charging structures can be provided. For example, refer to... Figure 6B The wireless charging structure may include a first wireless charging structure 530 disposed between the front panel 320 and the bracket 520, and a second wireless charging structure 530' disposed between the rear panel 380 and the bracket 520. The second wireless charging structure 530' can receive energy transferred from the charging device 10 through the rear panel 380. For example, the rear panel 380 of the electronic device 101 may face the charging device 10, and the charging device 10 may transfer energy to the second wireless charging structure 530'. The first wireless charging structure 530 can provide the generated energy to the charging receiving device 11 via the front panel 320. For example, the rear panel 380 of the electronic device 101 may face the charging receiving device 11, and the charging receiving device 11 may receive energy via the second wireless charging structure 530'.
[0143] According to embodiments of this disclosure, electronic device 101 can transfer energy to an external electronic device via a first wireless charging structure 530, and can receive energy from an external electronic device via a second wireless charging structure 530'. The first wireless charging structure 530 and the second wireless charging structure 530' can operate simultaneously or separately.
[0144] According to various embodiments of this disclosure, the magnetic plate 540 of the electronic device 101 can be disposed between the support 520 and the flexible printed circuit board 512. For example, the magnetic plate 540 can be formed to be stacked in the area where the wireless charging structure 530 can be disposed, in order to improve the charging efficiency of the wireless charging structure 530 and reduce surface heat generation. For example, when a conductive member (e.g., the support 520) is disposed directly on the back side of the wireless charging structure 530, eddy currents may be generated and therefore the energy generated by the charging device 10 may not be transferred, which may lead to reduced efficiency. Conversely, by disposing of the magnetic plate 540 with magnetism that induces magnetic flux between the support 520 and the wireless charging structure 530, the inflow of magnetic flux can be increased and interference from the support 520 can be prevented.
[0145] According to embodiments of this disclosure, the magnetic plate 540 is set as a sheet of paper of approximately 0.2 mm or less, and can be manufactured to cover the size of the wireless charging structure 530. For example, when the wireless charging structure 530 is set as a circle, the magnetic plate 540 can be set as a circle with a size corresponding to the wireless charging structure 530, or as a rectangle with a size covering the wireless charging structure 530.
[0146] According to various embodiments of this disclosure, the electronic device 101 may include a heat sink to suppress surface heat generation caused by the coil components of the wireless charging structure 530. The heat sink may be stacked together with the magnetic plate 540 and may include, for example, a graphite sheet.

[0148] refer to Figure 7 Electronic device 101 (e.g., Figures 1 to 4 The electronic device 101 may include a front panel 320, a rear panel 380, a display assembly 510, a bracket 520, a wireless charging structure 530, and a magnetic plate 540. As another example, the electronic device 101 may include a first antenna 551 or a second antenna 552 formed in at least one region of the bracket 520.
[0149] Figure 7 The front panel 320, rear panel 380, display assembly 510, bracket 520, and wireless charging structure 530 can be partially or completely integrated with the structure of the front panel 320, rear panel 380, display assembly 510, bracket 520, and wireless charging structure 530. Figure 6A and Figure 6B The front panel 320, rear panel 380, display component 510, bracket 520 and wireless charging structure 530 have the same structure.
[0150] Display assembly 510 may include a display panel 511 and a flexible printed circuit board 512 extending from and at least partially bent from the display panel 511. As another example, display assembly 510 may include an optical layer 513 and a dielectric layer 514 disposed on the front side of the display panel 511. As another example, display assembly 510 may include multiple layers (e.g., embossed layers and pads) on the back side of the display panel 511. In the following text, reference will be made to... Figure 6A The differences are described.
[0151] According to various embodiments of this disclosure, the flexible printed circuit board 512 of the display assembly 510 may be electrically connected to the display panel 511 and may include a first region 512a electrically connected to the display panel 511 and at least partially bent, and a second region 512b extending from the first region 512a and disposed between the bracket 520 and the display panel 511. For example, the first region 512a of the flexible printed circuit board 512 may extend from one end of the display panel 511 and may be bent toward the rear plate 380 (e.g., in a second direction (-Z)) to connect to the second region 512b.
[0152] According to various embodiments of this disclosure, the second region 512b of the flexible printed circuit board 512 can be substantially configured as a board, and the length of the second region 512b can correspond to the size of the display panel 511 of the electronic device 101. For example, the second region 512b may include a first shielding region 621 facing the first antenna 551 and a second shielding region 622 facing the second antenna 552. The first shielding region 621 and the second shielding region 622 may include copper (Cu) to prevent the inflow of electromagnetic waves generated from the first antenna 551 and the second antenna 552. As another example, when the second region 512b is provided with a size similar to that of the display panel 511, a heat sink (e.g., a graphite sheet) for heat dissipation may be provided on at least one surface of the second region 512b.
[0153] According to embodiments of this disclosure, the coil region 611 in which the wireless charging structure 530 is disposed may be located between the first shielding region 621 and the second shielding region 622 of the second region 512b. For example, the coil portions 531 of the wireless charging structure 530 disposed in the coil region 611 may be stacked on each conductive layer of the coil region 611 and may be electrically connected to each other through vias.
[0154] According to various embodiments of this disclosure, the magnetic plate 540 of the electronic device 101 can be disposed between the support 520 and the flexible printed circuit board 512. For example, the magnetic plate 540 can be formed to be stacked in the area where the wireless charging structure 530 can be disposed, so as to improve the charging efficiency of the wireless charging structure 530 and reduce surface heat generation.
[0155] According to embodiments of this disclosure, the magnetic plate 540 is configured as a flat sheet of approximately 0.2 mm or less and can be manufactured to a size capable of covering the wireless charging structure 530. The magnetic plate 540 can be formed to have a size corresponding to the size of the flexible printed circuit board 512. For example, when the electronic device 101 includes a display assembly 510 containing a digitizer, a magnetic plate 540 with a size corresponding to the size of the digitizer can be implemented to improve the performance of the digitizer and limit interference from electromagnetic waves from external components.
[0156] Figure 8 This is a schematic cross-sectional view illustrating a stacked structure of a flexible printed circuit board and peripheral components of an electronic device according to embodiments of the present disclosure.
[0157] See Figure 8 Electronic device 101 (e.g., Figures 1 to 4The electronic device 101 may include a front panel 320, a rear panel 380, a display assembly 510, a bracket 520, a wireless charging structure 530, and a magnetic plate 540. As another example, the electronic device 101 may include a first antenna 551 or a second antenna 552 formed in at least one region of the bracket 520.

Figure 6A The front panel 320, rear panel 380, display component 510, bracket 520, wireless charging structure 530 and magnetic plate 540 have the same structure.
[0159] According to various embodiments of the present disclosure, the flexible printed circuit board 512 of the display assembly 510 may be electrically connected to the display panel 511, and may include a first region 512a that is electrically connected to the display panel 511 and is at least partially bent, and a second region 512b that extends from the first region 512a and is disposed between the bracket 520 and the display panel 511.
[0160] According to various embodiments of this disclosure, the second region 512b may include a coil region 610 on which the wireless charging structure 530 is provided, and a shielding region 620 extending from the coil region 610. The shielding region 620 may be disposed adjacent to the first antenna 551 or the second antenna 552 of the electronic device 101, and may suppress the influence of electromagnetic waves generated by the first antenna 551 or the second antenna 552 on other components of the electronic device 101.
[0161] According to various embodiments of this disclosure, at least a portion of the shielding region 620 can be configured as the ground of the electronic device 101. For example, the shielding region 620 can be spaced apart from the metal region of the support 520 by a predetermined interval, and an AC connection structure can be achieved by forming a capacitor in specific areas where the shielding region 620 and the metal region face each other. As another example, at least a portion of the shielding region 620 can achieve a DC connection structure through a contact connection between the metal region of the support 520 and a conductive member (e.g., a conductive film).

In Table 1, shaded or shaded areas indicate that the materials are stacked.

[0169] According to embodiments of this disclosure, the thin copper plate constituting each circuit layer can function as a shielding layer for blocking electromagnetic interference (EMI). For example, the copper plate formed on each circuit layer can block electromagnetic wave interference, so that the electromagnetic waves generated by the first antenna 551 do not affect the peripheral electronic components of the electronic device 101.
[0170] According to various embodiments of this disclosure, Table 1 provides a cross-section of the coil region 610 of the flexible printed circuit board 512 taken along line B-B'.
