TECHNICAL FIELD

[0001] The present application relates to an electronic device, and particularly relates to an electronic device with a universal serial bus (USB) type-C interface and an operation method thereof. BACKGROUND

[0002] With the popularity of the universal serial bus type-C (USB type-C) and the lightening of existing mobile electronic devices, it is a future trend to transmit diversified functions such as data and charging through the USB type-C interface. When there are more and more electronic devices with the USB type-C interface in the market, compatibility problems between these devices will inevitably be a big challenge.

[0003] However, when users encounter compatibility problems of electronic devices with the USB type-C interface (for example, the electronic device cannot be charged or powered, cannot convert or output images, etc.), users will intuitively plug and unplug the USB type-C cable or the USB type-C interface device to make the electronic device work smoothly, but frequent plugging and unplugging will greatly reduce the convenience of the electronic device. SUMMARY

When a conversion error occurs during the conversion of the first image signal into the second image signal by the image conversion unit, the power delivery controller disconnects and then reconnects the first communication interface.

[0010] In some embodiments of the present application, the electronic device with the USB-C interface further comprises a USB interface. The USB interface is electrically connected to the first USB-C interface through a USB bus. When the USB interface is connected to a USB external device and the first USB-C interface is electrically connected to an external device, the external device inputs a first digital signal. When handshake of the first digital signal through the USB bus from the USB interface to the USB external device fails, the power delivery controller disconnects and then reconnects the first communication interface.

[0011] In some embodiments of the present application, the electronic device with the USB-C interface further comprises at least one second USB-C interface. The at least one second USB-C interface is electrically connected to the power delivery controller through at least one second communication interface. The at least one second USB-C interface is used to connect at least one external device. When the power delivery controller detects that a triggering event occurs, the power delivery controller stops communication of the at least one second communication interface and then reopens the communication of the at least one second communication interface.

[0013] In some embodiments of the present application, the second communication interface of the electronic device is electrically connected to the second universal serial bus (USB) Type-C interface of the electronic device, and the method further comprises: after the second USB Type-C interface is electrically connected to an external power supply, when the power delivery controller detects that a trigger event occurs, the second communication interface is first disconnected and then turned on, and then the first communication interface is disconnected and then turned on.

[0014] In some embodiments of the present application, the step of detecting the trigger event comprises: detecting the trigger event by a microcontroller of the electronic device, the microcontroller controls the disconnection or turn-on of the first communication interface, and the trigger event is that the first USB Type-C interface is connected to an external device, the power delivery controller handshake, the power delivery controller handshake fails, the image conversion fails, the USB handshake, or the USB handshake fails.

[0015] In summary, the technical solution of the present application has obvious advantages and beneficial effects compared with the prior art.

[0068] For the sake of making the description of the present application more detailed and complete, reference can be made to the accompanying drawings and various embodiments described below, in which the same or similar numbers represent the same or similar elements. On the other hand, well-known elements and steps are not described in the embodiments to avoid unnecessary limitations on the present application.

[0069] Figure 1 is a block diagram of an electronic device 100 having a universal serial bus (USB) Type-C interface according to some embodiments of the present application. As shown in FIG. 1, the electronic device 100 includes a power unit 610, a first switch unit 620, a second switch unit 920, a third communication interface 622, a fourth communication interface 922, and a controller 700. Figure 1As shown, the electronic device 100 comprises a power delivery controller (PD Controller) 110 and a first USB-C interface 180. In architecture, the first USB-C interface 180 is electrically connected to the power delivery controller through the first communication interface 130. In use, when the power delivery controller 110 detects a triggering event (e.g. the first USB-C interface 180 is connected to an external device 190, the power delivery controller 110 handshake, the power delivery controller 110 handshake failure, etc.), the power delivery controller 110 stops the communication of the first communication interface 130, and then re-enables the communication of the first communication interface 130. In this way, when the electronic device 100 has compatibility problems, the first USB-C interface 180 can be automatically reconnected, which can greatly improve the compatibility of the first USB-C interface 180 and provide a more comfortable user experience.

[0070] In some embodiments of the present application, the power delivery controller 110 stops the communication by turning off the first communication interface 130, and performs the communication by turning on the first communication interface 130. In implementation, for example, the first USB-C interface 180 is electrically connected to the power delivery controller 110 through the power bus 120 (e.g. VBus), and when the first USB-C interface 180 is electrically connected to the external device 190 (e.g. personal computer, tablet computer, game console, etc.), the external device 190 supplies power to the power delivery controller 110 through the power bus 120. The pins 115, 116 of the power delivery controller 110 are electrically connected to the first communication interface 130, and the power delivery controller 110 switches the pins 115, 116 to a first impedance state (e.g. high impedance state) to turn off the first communication interface 130 to stop the communication through the first communication interface 130, and then switches the pins 115, 116 to a second impedance state (e.g. low impedance state or impedance state preset according to specifications) to turn on the first communication interface 130 to perform the communication through the first communication interface 130. In this way, when the external device 190 supplies power to the power delivery controller 110 through the power bus 120, the power delivery controller 110 can turn off or turn on the first communication interface 130 by switching the impedance state of the pins 115, 116, without the need for additional hardware circuits. In some embodiments, the first USB-C interface 180 is electrically connected to the power management unit through the power bus 120 (e.g. VBus), and the power management unit is electrically connected to the power delivery controller 110 through the power bus 120 (e.g. VBus), and when the external device 190 supplies power to the power management unit through the power bus 120 (e.g. VBus), the power management unit supplies power to the power delivery controller 110 through the power bus 120 (e.g. VBus).

[0071] AsFigure 1 As shown, the power delivery controller includes logic gate 112 and microcontroller 111. For example, logic gate 112 may be a configuration channel (CC) logic circuit. Architecturally, logic gate 112 is electrically connected to the first communication interface 130 and the microcontroller 111. In use, the microcontroller 111 is used to detect trigger events and control the opening or closing of the first communication interface 130. In some embodiments of the present invention, logic gate 112 is used to receive, detect, and / or transmit signals from the first communication interface 130, enabling microcontroller 111 to detect trigger events based on the signals received from the first communication interface 130 by logic gate 112. The trigger events may be that the first universal serial bus C-type interface 180 is connected to an external device 190 (e.g., detecting that the voltage of at least one of pins 115 and 116 changes from a low level to a high level), the power delivery controller 110 is engaged, or the power delivery controller 110 is engaged and fails. Microcontroller 111 controls the impedance state of pins 115 and 116 of logic gate 112 to disconnect or connect the first communication interface 130.

[0072] In practice, the first communication interface 130 includes at least one interface (e.g., a configuration dedicated channel). For example, the first communication interface 130 includes a first interface 131 (e.g., a first configuration dedicated channel) and a second interface 132 (e.g., a second configuration dedicated channel). Architecturally, pins 115 and 116 of logic gate 112 are electrically connected to the first Universal Serial Bus Type-C interface 180 through the first interface 131 and the second interface 132. In use, logic gate 112 determines whether the insertion signal is positive or negative based on the information transmitted through the first interface 131 or the second interface 132, such as handshake information. Therefore, regardless of whether the external device 190 is inserted positively or negatively into the first Universal Serial Bus Type-C interface 180, the electronic device 100 can support the external device 190. In some embodiments, the handshake information includes, for example, the power supply capability information and data protocol format of the external device 190.

[0073] Figure 2 This is a block diagram of an electronic device 200 having a Universal Sequence Bus Type-C interface according to some embodiments of the present invention. Figure 2 Electronic devices 200 and Figure 1 The electronic device 100 has the same or similar components and functions, which will not be described further here. Compared to Figure 1 Electronic device 100, Figure 2The electronic device 200 also includes a power input terminal 290 (e.g., a power input interface, such as a DC power jack) and a power management unit 210 (e.g., a power management circuit). In some embodiments, the electronic device 200 further includes a power conversion circuit (not shown), such as an AC-to-DC circuit or a DC-to-DC circuit, electrically connected to the power input terminal 290 and the power management unit 210. Architecturally, the power input terminal 290 is electrically connected to the power management unit 210, and the power management unit 210 is electrically connected to a first universal serial bus Type-C interface 180 via a power bus 220. In use, when the power input terminal 290 is connected to an external power source, the power management unit 210 supplies power to the external device 190 via the first universal serial bus Type-C interface 180, thereby enabling the charging function of the external device 190.

[0074] Figure 3 This is a block diagram of an electronic device 300 having a Universal Sequence Bus Type-C interface according to some embodiments of the present invention. Figure 3 Electronic device 300 and Figure 2 The electronic device 200 has the same or similar components and functions, which will not be described again here. In one embodiment, Figure 3 The electronic device 300 also includes an image conversion unit 310 and an image output interface 370. In practice, for example, the power delivery controller 110 and the image conversion unit 310 can be integrated into the same chip (SoC) or separated into different circuits.

[0075] exist Figure 3 In this configuration, the image conversion unit 310 is electrically connected to the power delivery controller 110, the first universal sequence bus C-type interface 180, and the image output interface 370. When the first universal sequence bus C-type interface is electrically connected to an external device 190, if the power delivery controller 110 detects a triggering event (such as: the first universal sequence bus C-type interface 180 is connected to an external device 190, the power delivery controller 110 engages, the power delivery controller 110 engages but fails, the image conversion fails, etc.), the power delivery controller 110 stops the communication of the first communication interface 130 and then restarts the communication of the first communication interface 130.

[0076] In some embodiments of the present application, when the first USB-C interface 180 is electrically connected to the external device 190, the external device 190 inputs a first image signal (e.g., a DisplayPort (DP) image signal). The image conversion unit converts the first image signal into a second image signal (e.g., a High-Definition Multimedia Interface (HDMI) image signal, a Digital Visual Interface (DVI) signal, a Video Graphics Array (VGA) signal, or another image signal). If the image output interface 370 (e.g., an HDMI, a DVI, a VGA, or another output interface) is communicatively connected to an image output device (e.g., a display, a screen, a projector, or the like), the image output interface 370 outputs the second image signal to the image output device.

[0077] Regarding image conversion failure, when a conversion error occurs during the conversion of the first image signal into the second image signal by the image conversion unit 310, the power delivery controller 110 disconnects and then reconnects the first communication interface 130. In this way, when the electronic device 300 has a compatibility problem, the electronic device 300 can automatically reconnect the first USB-C interface 180, and the user does not need to manually re-plug the external device 190, thereby improving the user experience.

[0078] In some embodiments, Figure 3 The electronic device 300 further includes a USB interface 320, an image conversion unit 310, and an image output interface 370. In Figure 3 In some embodiments, the USB interface 320 is electrically connected to the first USB-C interface 180 through a USB 3.2 Gen 2 Type-C 322. In use, when the power delivery controller 110 detects a trigger event (e.g., the first USB-C interface 180 is connected to the external device 190, power delivery controller 110 handshake, power delivery controller 110 handshake failure, USB handshake, USB handshake failure, or the like), the power delivery controller 110 stops the communication of the first communication interface 130, and then re-enables the communication of the first communication interface 130.

[0079] Regarding Universal Serial Bus (USB) handshake failure, in some embodiments of the present invention, when the USB interface 320 is connected to the USB external device 390 (e.g., an image capturing device, video recorder, computer, streaming device, live streaming device, etc.) and the first USB Type-C interface 180 is electrically connected to the external device 190, the external device 190 inputs a first digital signal. When the handshake of the first digital signal through the USB 322, USB interface 320, and USB external device 390 fails, the power delivery controller 110 disconnects and then reconnects the first communication interface 130. Thus, when the electronic device 300 experiences a compatibility problem, it can automatically reconnect to the first USB Type-C interface 180, eliminating the need for the user to manually unplug and replug the USB external device 390, thereby improving the user experience.

[0080] Figure 4 This is a block diagram of an electronic device 400 having a Universal Sequence Bus Type-C interface according to some embodiments of the present invention. Figure 4 Electronic device 400 and Figure 3 The electronic device 300 has the same or similar components and functions, which will not be described further here. Compared to Figure 3 Electronic device 300, Figure 4 The electronic device 400 also includes at least one second general sequence bus C-type interface 480. In some embodiments of the invention, the number of second general sequence bus C-type interfaces 480 is one or more, and the number of external devices 490 (e.g., personal computers, tablet computers, game consoles, etc.) and logic gates 112 is correspondingly one or more.

[0081] exist Figure 4 In this configuration, the second universal serial bus Type-C interface 480 is electrically connected to the power delivery controller 110 via the second communication interface 430. During use, the second universal serial bus Type-C interface 480 is used to connect the external device 490. When the power delivery controller detects a trigger event, it stops communication via the second communication interface 430 and then resumes communication via the second communication interface 430. This allows for automatic reconnection of the second universal serial bus Type-C interface 480 when compatibility issues arise with the electronic device 400, eliminating the need for manual unplugging and replugging of the external device 490 and improving the user experience.

[0082] In some embodiments of the present invention, the power delivery controller 110 first disconnects and then reconnects the second communication interface 430, and then disconnects and reconnects the first communication interface 130.

[0083] In practice, the second communication interface 430 includes at least one interface (e.g., a configuration dedicated channel). For example, the second communication interface 430 includes a first interface 431 (e.g., a first configuration dedicated channel) and a second interface 432 (e.g., a second configuration dedicated channel). Architecturally, the pins of logic gate 112 are electrically connected to the second communication interface 430 through the first interface 431 and the second interface 432. In use, logic gate 112 uses the information transmitted by the first interface 431 or the second interface 432 (e.g., handshake information) to determine whether the insertion signal is positive or negative. Therefore, regardless of whether the external device 490 is inserted positively or negatively into the second general sequence bus C-type interface 480, the electronic device 400 can support the external device 490. In some embodiments, the handshake information includes, for example, the power receiving capability information and data protocol format of the external device 190.

[0084] Figure 5 This is a block diagram of an electronic device 500 having a Universal Sequence Bus Type-C interface according to some embodiments of the present invention. Figure 5 Electronic device 500 and Figure 3 The electronic device 300 has the same or similar components and functions, which will not be described again here. In some embodiments of the present invention, Figure 5 The second general sequence bus C-type interface 580 can replace the function of the second general sequence bus. Figure 3 The functions of the power input terminal 290 and the power management unit 210.

[0085] exist Figure 5 In this configuration, the second Universal Sequence Bus Type-C interface 580 is electrically connected to the power delivery controller 110 via the second communication interface 530. After an external power supply 590 (e.g., a power supply with a Universal Sequence Bus Type-C interface) is electrically connected to the second Universal Sequence Bus Type-C interface 580, when the power delivery controller 110 detects a trigger event, it first disconnects and then reconnects the second communication interface 530, and then disconnects and reconnects the first communication interface 130. In this way, the electronic device 500 more effectively improves the compatibility issues of the Universal Sequence Bus Type-C interface.

[0086] In some embodiments, the power delivery controller 110 can first disconnect and then reconnect the first communication interface 130, and then disconnect and reconnect the second communication interface 530 to improve the compatibility of the Universal Sequence Bus C-type interface.

[0087] In some embodiments of the present invention, the second Universal Serial Bus Type-C interface 580 is electrically connected to the first Universal Serial Bus Type-C interface 180 via a power bus 220. In use, power supplied by the external power supply 590 is provided to the external device 190 through the first Universal Serial Bus Type-C interface 180.

[0088] In practice, the second communication interface 530 includes at least one interface (e.g., a configuration dedicated channel). For example, the second communication interface 530 includes a first interface 531 (e.g., a first configuration dedicated channel) and a second interface 532 (e.g., a second configuration dedicated channel). Architecturally, the pins of logic gate 112 are electrically connected to the second communication interface 530 through the first interface 531 and the second interface 532. In use, logic gate 112 uses information transmitted through the first interface 531 or the second interface 532 (e.g., handshake information) to determine whether the connection is positive or negative. Therefore, regardless of whether the external power supply 590 is positively or negatively connected to the second universal serial bus C-type interface 580, the electronic device 500 can support the external power supply 590. In some embodiments, the handshake information includes, for example, information about the power supply capability of the external device 590.

[0090] exist Figure 6 In this configuration, the power delivery controller 110 is electrically connected to the first switching unit 620 via a third communication interface 622 (e.g., an inter-integrated circuit bus, a general-purpose input / output, etc.). During use, the power delivery controller 110 (e.g., an internal microcontroller 111) sends a switching signal to control the first switching unit 620 to disconnect or connect the first communication interface 130.

Additionally, power unit 610 is electrically connected to a first universal serial bus Type-C interface 180. In some embodiments, an external device 190 can charge power unit 610 via the first universal serial bus Type-C interface 180 during use.

[0101] To make the operation method of the electronic device 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 more clearly, please refer to the flow chart of the operation method 1100 of the electronic device 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 according to an embodiment of the present application. Figures 1 to 11 , Figure 11 is the flow chart of the operation method 1100 of the electronic device 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 according to an embodiment of the present application. As shown in Figure 11 , the operation method 1100 comprises steps S1101, S1102 (it should be understood that the order of the steps mentioned in this embodiment can be adjusted according to actual needs, even simultaneously or partially simultaneously, except for the order specified).

[0102] The operation method 1100 can be in the form of a computer program product on a non-transitory computer readable recording medium, which has computer readable instructions contained in the medium. Suitable recording media can include any of the following: non-volatile memory, such as read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM); volatile memory, such as static access memory (SRAM), dynamic access memory (DRAM), double data rate random access memory (DDR-RAM); optical storage devices, such as compact discs read-only memory (CD-ROM), digital versatile discs read-only memory (DVD-ROM); magnetic storage devices, such as hard drives, floppy drives.

[0103] At step S1101, a trigger event is detected. At step S1102, when the trigger event is detected, the communication of the first communication interface 130 is stopped, and then the communication of the first communication interface 130 is started again, thereby greatly improving the compatibility problem of the first universal serial bus (USB) interface 180, and the user experience is more comfortable.

[0104] In some embodiments of the present application, the second communication interface 530 is electrically connected to the second universal serial bus (USB) interface 580, and the operation method 1100 further comprises: after the second universal serial bus (USB) interface 580 is electrically connected to the external power supply 590, when the power delivery controller 110 detects that a trigger event occurs, the second communication interface 530 is first disconnected and then turned on, and then the first communication interface 130 is disconnected and then turned on. By preferentially turning off the power-related second communication interface 530, the compatibility problem of the first universal serial bus (USB) interface 180 can be further greatly improved, and the user experience is more comfortable.

[0105] In some embodiments of the present application, at step S1101, the microcontroller 111 detects a triggering event, and the microcontroller 111 controls the first communication interface 130 to be disconnected or turned on. The triggering event may, for example, be that the first USB-C interface 180 has a connected external device 190, that the power delivery controller 110 handshake, that the power delivery controller 110 handshake fails, that the image conversion fails, that the USB handshake fails, that the USB handshake fails, or other compatibility events.

[0106] In summary, the technical solutions of the present application have obvious advantages and beneficial effects compared with the prior art. The electronic device 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 with the USB-C interface and the operation method 1100 thereof of the present application utilize the characteristics of the USB-C interface. When the electronic device 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 has a compatibility problem, the first USB-C interface 180 can be automatically reconnected. This can greatly improve the compatibility problem of the first USB-C interface 180, and the user experience is more comfortable.

Any person skilled in the art can make various changes and modifications without departing from the concept and scope of the present application.
