[0048] See also Figure 1 to Figure 2 , Figure 1 A flowchart of a method for waking up a terminal device in an embodiment of the present application is shown; Figure 2 A structural block diagram of a display device according to an embodiment of the present application is shown.

[0049] like Figure 1 and Figure 2 As shown, according to a first aspect of an embodiment of the present application, a terminal device wake-up method is provided, which is applied to a display device, wherein the display device includes a first processor, a second processor and at least one uplink interface, at least one of the uplink interfaces is used to connect to the terminal device, the first processor is used to exchange wake-up data with the terminal device through the uplink interface, and the second processor is used to notify the first processor to start communication with the terminal device; the method is implemented but not limited to steps S101 to S102:

[0050] Step S101. The second processor sends a first message for a terminal device to the first processor, where the first message is used to notify the first processor to start communication with the terminal device;

[0051] Step S102: The first processor exchanges wake-up data with the terminal device via an uplink interface connected to the terminal device to wake up the terminal device from a non-working state to a working state.

[0052] Based on the above disclosed content, the embodiment of the present application sets a first processor, a second processor and at least one uplink interface in a display device, and at least one uplink interface is used to connect to a terminal device. The first processor communicates and exchanges data with the terminal device through the uplink interface to wake up the terminal device to a working state. The terminal device itself does not need to be configured with a special wake-up component, which improves the simplicity of the terminal device system and thereby improves the user experience.

[0053] It is understandable that by integrating the hardware and software protocols for waking up the terminal in the display device, the terminal device can be awakened through the display device, which can make the terminal device system more concise, and the benefits can be: in line with the design trend of ultra-thin bodies of laptops, the design trend of miniaturized hosts of desktop computers, etc. In addition, by executing functions such as terminal wake-up through the display device, it can provide users with diversified terminal wake-up product choices and improve user experience.

[0054] It should be noted that the terminal device may be a desktop computer host, a laptop computer, a mobile phone, a tablet computer, a wearable device, a vehicle-mounted terminal, and other terminal devices, which will not be described one by one with examples here.

[0055] It should be noted that if Figure 2 As shown, the display device of the embodiment of the present application is provided with at least one uplink interface, that is, the display device can be connected to one terminal device through the uplink interface, or it can be connected to two terminal devices, or even multiple terminal devices. The interface setting and terminal device connection can be performed according to actual application requirements, which is not limited here.

[0056] The terminal device being in a non-working state means that the terminal device is in a low power consumption state, such as a sleep state, a hibernation state, and a shutdown state.

[0057] It should be noted that before waking up the terminal device through the display device of the embodiment of the present application, the terminal device should be connected to a power source, and the display device should at least be in a standby state to ensure that normal data exchange can be performed between the terminal device and the display device. If the display device is in a powered-off state, the display device should be powered on through a button on the display device, such as a power button.

[0058] It should be noted that, depending on the non-working state of the terminal device, the state of the components in the display device may also be different. For example: if the terminal device is in a sleep state, the components in the display device are powered on; if the terminal device is in a dormant state or a shutdown state, the components in the display device other than the components that perform the terminal wake-up may be powered off. The components that perform the terminal wake-up include but are not limited to the first processor, the second processor, and the uplink interface.

[0059] It can be understood that an application scenario of the terminal device wake-up method of an embodiment of the present application may be: a user has a display device and a terminal device connected to the display device in a first place, and the first place may be an office place; after the user leaves the first place, based on usage needs, such as remote office, it is necessary to wake up the terminal device first; then, the user can use the remote terminal to send a message to the display device so as to wake up the terminal device through the display device, and the remote terminal includes but is not limited to the user's smartphone, tablet computer, laptop computer, etc.

[0060] It is understandable that an application scenario of the terminal device wake-up method of the embodiment of the present application may be: a user has a display device and two terminal devices connected to the display device at a first location, one of the terminal devices is in a non-working state, and the other terminal device is in a working state. The terminal device in a non-working state can be woken up by the other terminal device connected to the display device.

[0061] It can be understood that an application scenario of the terminal wake-up method of an embodiment of the present application may be: a user has a display device and a terminal device connected to the display device, and a wake-up trigger mechanism is provided inside the display device. When a preset condition is met, the display device wakes up the terminal device through the wake-up trigger mechanism.

[0062] Of course, it is understandable that the application scenarios of the terminal device wake-up method of the embodiment of the present application are not limited to the above examples.

[0063] In some embodiments, the first processor may be an integrated circuit chip encapsulated with a communication protocol, such as a PD (power delivery) chip, and the communication protocol may be a VDM (Vendor-Defined Message) protocol, so that the first processor can use the communication protocol to exchange wake-up data with the terminal device, thereby waking up the terminal device from a non-working state to a working state.

[0064] In some embodiments, the second processor may be an image processing chip provided by the display device, such as a scaler chip, etc. The scaler chip may be packaged separately from the PD chip, or may be packaged as a whole after being integrated with the PD chip. When the scaler chip and the PD chip are packaged separately, the scaler chip transmits messages with the PD chip through the IIC channel, for example, the scaler chip sends the first message to the PD chip through the IIC channel. Among them, the advantage of using the scaler chip provided by the display device to assist in realizing terminal wake-up is that the terminal wake-up function of the embodiment of the present application is realized by using the existing image processing chip, thereby reducing the hardware cost.

[0065] In some embodiments, the upstream interface includes but is not limited to a USB interface, such as a USB-B interface and a USB-C interface. By providing multiple upstream interfaces on the display device, each of which is used to connect to each terminal device, multiple terminal devices can share one display device, and when the terminal device is in a non-working state, each terminal device can be awakened by one display device. In addition, by using different types of upstream interfaces, the display device can also be adapted to terminal devices with different downstream interfaces, such as a computer host with a USB-A interface, a laptop with a USB-C interface, etc.

[0066] In step S101, when the terminal device is in a non-working state, a first message is sent to the first processor through the second processor, and the first message is used to trigger the first processor to start communication with the terminal device. For example: when the scaler chip and the PD chip are independently packaged, the scaler chip sends the first message to the PD chip through the IIC channel; when the scaler chip and the PD chip are integrated and packaged, the scaler chip directly sends the first message to the PD chip. After receiving the first message, the PD chip enters a state in which it can communicate with the terminal device. Among them, one of the implementation methods of the PD chip being able to communicate with the terminal device can be: the terminal device also has a built-in PD chip, and the PD chip of the display device and the PD chip of the terminal device establish communication through handshake. Specifically, communication is established by connecting the cc_pin pins of the two PD chips.

[0067] In step S101, one of the ways to generate the first message may be: the second processor has a built-in mechanism for generating the first message, for example: a timer is set in the second processor, and the first message is generated regularly by the timer.

[0068] In step S101, another way of generating the first message may be: the display device further includes a trigger component; and the second processor receives a second message sent by the trigger component to generate the first message.

[0069] In some implementations, the trigger component includes a remote trigger component, and the remote trigger component is used to receive a third message sent by a remote terminal and generate the second message according to the third message.

[0070] It can be understood that the remote trigger component refers to a component that receives a third message sent by an external remote terminal through a network, including but not limited to a wired network card, a wireless network card, etc.

[0071] When a wired network card is used, the wired network card is connected to an external network device through a network port to access the Internet, such as by connecting to a router to access the Internet; when a wireless network card is used, the wireless network card can be connected to an external network device through its own wireless communication module to access the Internet, such as by connecting to a wireless router through a WiFi module or a Bluetooth module to access the Internet.

[0072] The external remote terminal may be any terminal that can be connected to the remote trigger component through a network, such as a smart phone, a laptop, a wearable device, a tablet computer, etc. The third message sent by the external remote terminal may be a data packet based on a network wake-up protocol, such as a magic packet based on a WOL protocol.

[0073] When the remote trigger component receives the third message, the second message is generated according to the third message. For example, when the wired network card receives the magic packet sent by the external laptop, the level of the Lan wake_CTL (network wake-up) pin of the wired network card changes, such as from a high level to a low level, and sends the message of the change of its own level as the second message to the second processor, such as to the scaler chip.

[0074] In some implementations, the trigger component includes a local trigger component, and the local trigger component is used to receive a fourth message triggered by an external device and generate the second message according to the fourth message.

[0075] It can be understood that the local trigger component refers to a trigger component set in the display device and capable of connecting to an external device of the display device, including but not limited to a trigger interface, an audio receiving module, a biometric information recognition module, etc.

[0076] When a trigger interface is used, the trigger interface may be a downstream interface, such as a USB-A interface, and the external device may be an external device such as a mouse and a keyboard, and the user may send the fourth message to the trigger interface by operating the mouse or the keyboard, etc. In addition, the trigger interface may also be an interface connected to a shortcut key, and the shortcut key is set on the display device, and the user may send the fourth message to the trigger interface by operating the shortcut key.

[0077] When an audio receiving module is used, the audio receiving module may be a microphone, etc., and the external device may be a speaker, etc. The speaker sends the fourth message to the microphone. It is understandable that the user may also send a voice message directly to the microphone, and use the voice message as the fourth message.

[0078] When a biometric information recognition module is used, the biometric information may be facial information, fingerprint information, etc. Correspondingly, the biometric information recognition module may be a facial recognition module or a fingerprint recognition module, and the user may send the fourth message by entering facial information or fingerprint information.

[0079] Based on the above disclosed content, it can be known that when the terminal device is awakened by the display device, the display device can wake up the terminal device by receiving a remote wake-up message, or by receiving a local wake-up message, thereby meeting the user's terminal wake-up needs in various scenarios and improving the user experience.

[0080] In some implementations of step S102, the first processor exchanges wake-up data with the terminal device through an uplink interface connected to the terminal device, including:

[0081] The first processor exchanges wake-up data with the terminal device using the VDM protocol via a USB-C interface connected to the terminal device.

[0082] It should be noted that the VDM (Vendor Defined Message) protocol refers to the protocol defined in the USB Association's Universal Serial Bus Power Delivery Specification spec file. VDM includes two types: structured VDM and unstructured VDM. Among them, structured VDM defines an extensible structure designed to support modal operations.

[0083] For example, in Figure 2In the embodiment, the first processor is a PD chip, the second processor is a scaler chip, the trigger component is a wired network card, the upstream interface is a USB-C interface, and when the terminal device is in a dormant state or a sleeping state, the wake-up process of the terminal device is as follows:

[0084] After the wired network card Ethernet controller 2 receives the network magic packet magicpacket sent by the remote terminal, the "Lanwake_CTL" pin of the wired network card is pulled down to a low level, and the scaler chip is notified of the level change; then, the scaler chip notifies the PD chip through the IIC channel; the PD chip starts VDM protocol communication, transmits specific protocol data in the CC pin of USB-C, and exchanges data through the CC protocol to wake up the terminal device.

[0085] See also Figure 3 , shows another flow chart of the terminal device wake-up method according to an embodiment of the present application.

[0086] Based on the structured VDM, the embodiments of the present application define the instructions that can be defined by the user in the protocol, such as Figure 3 As shown in , the embodiment of the present application names the reserved part of the instruction as "Get Status", and the custom instruction is used to implement the wake-up data exchange between the PD chip and the terminal device.

[0087] In some implementations, the first processor uses the VDM protocol to exchange wake-up data with the terminal device through the USB-C interface connected to the terminal device, and the specific process includes:

[0088] Step S01: Sending a notice to the terminal device;

[0089] For example, the PD chip sends an attention VDM (attention notification) to NB / PC1 (terminal device) to remind NB / PC1 to wake it up from a non-working state to a working state; wherein NB refers to a Notebook computer, and PC1 refers to a first personal computer (eg, a host).

[0090] Step S02: receiving a first instruction sent by the terminal device, wherein the first instruction is used to indicate that the terminal device intends to obtain content corresponding to the attention notification;

[0091] For example: after receiving the attention notification, NB / PC1 replies "good CRC" to the PD chip (a message indicating that the attention notification has been correctly received by NB / PC1), and sends a predefined first instruction, namely "Get Status", to the PD chip, indicating that the terminal device intends to obtain the content corresponding to the attention notification from the PD chip.

[0092] Step S03: Sending a second instruction to the terminal device, wherein the second instruction is used to indicate to the terminal device that it is intended to be awakened from a non-working state to a working state through a wake-up mechanism;

[0093] For example, the PD chip responds with "good CRC" and sends a predefined second instruction, namely "Get Status", to explain to the terminal device that it is intended to wake it up from a non-working state to a working state through a wake-up mechanism.

[0094] Step S04: receiving a third instruction sent by the terminal device, wherein the third instruction is used to indicate that the terminal device agrees to wake it up from a non-working state to a working state;

[0095] For example, after receiving the second instruction, NB / PC1 replies "good CRC" to the PD chip (a message indicating that the second instruction has been correctly received by NB / PC1), indicating that it agrees with the terminal device wake-up request of the PD chip. At the same time, NB / PC1 requests PD to stop sending the second instruction, that is, to request PD to clear the corresponding instruction status, such as clearing the System ACK instruction.

[0096] Step S05: Agree to stop sending the target request of the second preset instruction to the terminal device so that the terminal device wakes itself up from a non-working state to a working state, and the target request is the request carried by the terminal device in the third preset instruction.

[0097] For example: the PD chip responds to "good CRC" (a message indicating that the second instruction has been correctly received by NB / PC1) and agrees to the target request, so that the relevant program inside NB / PC1 runs and is awakened from the non-working state to the working state.

[0098] Based on the above disclosed content, it can be known that when waking up the terminal device through the first processor, the second processor and the upstream interface of the display device, multiple message reception or sending is required. Therefore, the above method is more applicable to the following scenarios: the terminal device is in sleep state or shutdown state, the system enters a deeper sleep state, and the terminal device cannot be directly awakened through the upstream interface of the display device.

[0099] If the terminal device is in a sleep state, the terminal device can be awakened by directly sending the second message to the USB-C interface or the USB-B interface by triggering the component instead of receiving the first message from the second processor, so as to reduce the number of data exchanges and speed up the awakening process.

[0100] In some implementations, the upstream interface includes a USB-C interface and a USB-B interface, and the method further includes:

[0101] The first processor forwards the second message sent by the trigger component to the USB-C interface or the USB-B interface, so that the USB-C interface or the USB-B interface exchanges wake-up data with the terminal device to wake up the terminal device from a non-working state to a working state;

[0102] If the terminal device is not awakened from the non-working state to the working state, the second processor sends a first message for the terminal device to the first processor.

[0103] It is understandable that the display device can try to wake up the terminal device by sending a second message to the USB-C interface or the USB-B interface without detecting the non-working state of the terminal device. If the terminal device can be awakened, it means that the terminal device is in a relatively shallow non-working state, such as a sleep state. If the terminal device cannot be awakened, it means that the terminal device is in a relatively deep non-working state, such as a sleep state or a shutdown state. At this time, the display device needs to exchange wake-up data with the terminal device through a preset communication protocol in order to wake up the terminal device.

[0104] As a practical application of the present application, for example, laptop A is connected to a display device via an uplink interface, and laptop B is connected to the display device via a network. When laptop A is awakened by laptop B, the user can enable the Ethernet port connected to laptop A in the OSD menu of the display device interface. Then the wake-up operation is performed in the manner shown in the following table:

[0105]

[0106] The following describes an embodiment of the device of the present application, which can be used to execute the method in the above embodiment of the present application. For details not disclosed in the embodiment of the device of the present application, please refer to the above embodiment of the method of the present application.

[0107] See also Figure 4 , shows a structural block diagram of a terminal device wake-up device according to an embodiment of the present application.

[0108] like Figure 4 As shown, according to a second aspect of an embodiment of the present application, a terminal device wake-up device 200 is provided, which is provided in a display device, wherein the display device includes a first processor, a second processor and at least one uplink interface, at least one of the uplink interfaces is used to connect to the terminal device, the first processor is used to exchange wake-up data with the terminal device through the uplink interface, and the second processor is used to notify the first processor to start communication with the terminal device; the device includes:

[0109] A message sending unit 201, configured for the second processor to send a first message for a terminal device to the first processor, wherein the first message is used to notify the first processor to start communication with the terminal device;

[0110] The data exchange unit 202 is used for the first processor to exchange wake-up data with the terminal device through an uplink interface connected to the terminal device, so as to wake up the terminal device from a non-working state to a working state.

[0111] like Figure 2 As shown, according to the third aspect of an embodiment of the present application, a display device is provided, including a first processor, a second processor and at least one uplink interface, at least one of the uplink interfaces is used to connect to a terminal device, the first processor is used to exchange wake-up data with the terminal device through the uplink interface, and the second processor is used to notify the first processor to start communication with the terminal device.

[0112] Based on the above disclosed content, the embodiment of the present application sets a first processor, a second processor and at least one uplink interface in a display device, and at least one uplink interface is used to connect to a terminal device. The first processor communicates and exchanges data with the terminal device through the uplink interface to wake up the terminal device to a working state. The terminal device itself does not need to be configured with a special wake-up component, which improves the simplicity of the terminal device system and thereby improves the user experience.

[0113] It is understandable that by integrating the hardware and software protocols for waking up the terminal in the display device, the terminal device can be awakened through the display device, which can make the terminal device system more concise, and the benefits can be: in line with the design trend of ultra-thin bodies of laptops, the design trend of miniaturized hosts of desktop computers, etc. In addition, by executing functions such as terminal wake-up through the display device, it can provide users with diversified terminal wake-up product choices and improve user experience.

[0114] In some embodiments, the first processor may be an integrated circuit chip encapsulated with a communication protocol, such as a PD (power delivery) chip, and the communication protocol may be a VDM (Vendor-Defined Message) protocol, so that the first processor can use the communication protocol to exchange wake-up data with the terminal device to implement a wake-up function.

[0115] In some embodiments, the second processor may be an image processing chip provided by the display device, such as a scaler chip, etc. The scaler chip may be packaged separately from the PD chip, or may be packaged as a whole after being integrated with the PD chip. When the scaler chip and the PD chip are packaged separately, the scaler chip transmits messages with the PD chip through an IIC channel. Among them, the advantage of using the scaler chip provided by the display device to assist in realizing terminal wake-up is that there is no need to add a dedicated terminal wake-up component in the display device, thereby reducing hardware costs.

[0116] In some implementations, the scaler chip can be connected to an HDMI2.0 x1 interface and a DP1.2input x2 interface for plugging a video transmission line to implement video data transmission of a terminal device.

[0117] In some embodiments, the upstream interface includes but is not limited to a USB interface, such as a USB-B interface and a USB-C interface. By providing multiple upstream interfaces on the display device, each of which is used to connect to each terminal device, multiple terminal devices can share one display device, and when the terminal device is in a non-working state, each terminal device can be awakened by one display device. In addition, by using different types of upstream interfaces, the display device can also be adapted to terminal devices with different downstream interfaces, such as a computer host with a USB-A interface, a laptop with a USB-C interface, etc.

[0118] See also Figure 5 , shows a structural block diagram of another display device according to an embodiment of the present application.

[0119] like Figure 5 As shown, in some embodiments, the display device includes:

[0120] At least two uplink interfaces, each of which is used to connect to a terminal device;

[0121] At least one Internet access module is connected to each of the uplink interfaces to implement network access for terminal devices connected to each of the uplink interfaces.

[0122] It can be understood that by integrating the Internet access module into the display device, the display device is provided with multiple upstream interfaces for connecting various terminal devices, so that it is possible to achieve the effect of one display device supporting multiple terminal devices to access the Internet at the same time; and, integrating the Internet access module into the display device can further improve the simplicity of the terminal device system, which is in line with the design trend of ultra-thin body of laptop computers, the design trend of miniaturized host of desktop computers, etc.

[0123] For example: Figure 5 In the figure, two upstream interfaces, a USB-C interface and a USB-B interface, and two Internet access modules, Ethernt controller 1 (Ethernet controller 1) and Ethernt controller 2 (Ethernet controller 2), are shown, wherein the Ethernet controller 1 is connected to the USB-C interface for realizing the Internet access function of the terminal device connected to the USB-C interface; the Ethernet controller 2 is connected to the USB-B interface for realizing the Internet access function of the terminal device connected to the USB-B interface.

[0124] See also Figure 6 , showing a schematic diagram of the connection between two terminal devices and a display device in an embodiment of the present application.

[0125] It is understandable that one of the application scenarios of the display device with Internet access function in the embodiment of the present application may be: Figure 6 As shown, the user's home is equipped with a host, a monitor and a laptop. The monitor can be connected to the laptop and the host at the same time, avoiding the problem in the prior art that the display device can only support one terminal device to access the Internet and needs to be repeatedly plugged and unplugged when switching terminal devices.

[0126] It can be understood that one of the application scenarios of the display device with Internet access function in the embodiment of the present application may be: in certain industrial applications, such as electrical control rooms, workstations, etc., multiple hosts are set up, and by connecting the display device with Internet access function to multiple hosts at the same time, one display device can support multiple hosts to be connected to the Internet at the same time, and the working status of multiple work points can be monitored through one display device, thereby improving the simplicity of the system.

[0127] In some embodiments, the upstream interface includes a USB-B interface and a USB-C interface;

[0128] The USB-B interface is connected to the Internet access module;

[0129] The USB-C interface is connected to the first processor, and the first processor is connected to the Internet access module.

[0130] It can be understood that if the upstream interface is a USB-B interface, the corresponding connected terminal device can be an interface with a USB-A; if the upstream interface is a USB-C interface, the corresponding connected terminal device can be an interface with a USB-C.

[0131] In some embodiments, the display device includes a USB-B interface and a USB-C interface, the USB-B interface is used to connect to a terminal device having a USB-A interface, and the USB-C interface is used to connect to a terminal device having a USB-C interface.

[0132] When the upstream interface is a USB-C interface, in order to further expand the function of the USB-C interface, the first processor is connected and then connected to the Internet access module, so that the transmission protocol with the terminal device can be managed. For example, the USB-C interface and the Internet access module are connected respectively through a PD chip to manage the transmission protocol between the USB-C interface and the terminal device.

[0133] In some implementations, in order to manage the data transmission channels of the USB-C interface, a multiplexer MUX is provided, and the multiplexer MUX is integrated in the PD chip. Specifically, there are four transmission channels between the PD chip and the USB-C chip, namely rx1, rx2, tx1 and tx2. When the USB-C data is transmitted to the PD chip through the four transmission channels, the distribution channel of the data transmitted to the PD chip is controlled by the multiplexer MUX.

[0134] In some implementations, the terminal device includes a first Internet access module and a second Internet access module, the first Internet access module is connected to the USB-B interface, and the second Internet access module is connected to the USB-C interface.

[0135] In some implementations, the Internet access module includes a wired network control unit and a network port, and the wired network control unit is connected to an external network device through the network port.

[0136] It should be noted that the wired network control unit can be a wired network card, and the network port can be an Ethernet port. By plugging one end of the network transmission cable into the Ethernet port and the other end into an external network device, such as a router, multiple terminal devices can access the Internet at the same time.

[0137] In some embodiments, when multiple wired network control units are provided, such as Figure 5In the Etherntcontroller1 (Ethernet controller 1) and Ethernt controller2 (Ethernet controller 2), the display device is also provided with a network hub, such as Figure 5 The Ethernet HUB in the network can distribute the network signal input from the network port to each wired network control unit, realize the simultaneous transmission of network signals in multiple directions, and enable multiple terminal devices to access the Internet at the same time.

[0138] In some embodiments, the Internet access module includes a wireless network control unit, which may be a wireless network card. The wireless network card communicates with an external network device via an internal wireless communication module, such as communicating with a router via a WiFi module or a Bluetooth module.

[0139] In some embodiments, the display device further includes:

[0140] At least one first hub, the at least one first hub is connected to each of the uplink interfaces and each of the Internet access modules.

[0141] like Figure 5 As shown in the figure, it includes a first hub USB HUB1 and USB HUB2, USB HUB1 is connected to the USB-C interface and Ethernet controller 1, and USB HUB2 is connected to Ethernet controller 2. When there are multiple Internet access modules or multiple upstream interfaces, the first hub can realize the integration and distribution of network signals or USB signals.

[0142] It should be noted that the first hub USB HUB1 and USB HUB2 of the embodiment of the present application can adopt a one-to-two model, that is, one upstream signal interface and two downstream signal interfaces. Of course, other models can also be adopted, which are specifically set according to the requirements of the connection line and are not limited here.
