[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0044] The embodiment of the present application provides a firmware upgrade method, which is applied to a connection device, such as Figure 1 As shown, the firmware upgrade method includes the following steps:

[0045] S101, detecting a firmware upgrade instruction received from an electronic device, and obtaining interface information of a communication interface to which a target display is connected.

[0046] In this embodiment, the target display is a display that needs to be upgraded with firmware. The target display is connected to the electronic device through a connection device. The connection device includes a docking station, an adapter, etc.

[0047] In this embodiment, the number of target displays can be one or more. If there are multiple target displays, the types of communication interfaces to which the multiple target displays are connected can be the same or different. For example, as Figure 2 shown, the electronic device can be connected to the connection device through a USB-A / USB-C / Thunderbolt interface (TBT); the connection device can be connected to Display 1 through a High-Definition Multimedia Interface (HDMIport), can be connected to Display 2 through a DisplayPort (DP port), and can be connected to Display 3 through a Type-C interface (USB Type-C port, USB-C port) or TBT4. If only Display 1 needs to be upgraded with firmware, then Display 1 is the target display. If Displays 1, 2, and 3 need to be upgraded with firmware at the same time, then Displays 1, 2, and 3 are the target displays.

[0048] In this embodiment, the interface information may include the communication interface type, the communication interface identifier, and the communication interface location. The communication interface type includes a High-Definition Multimedia Interface (HDMI), a display interface, a USB Type-C interface, etc. The communication interface identifier may be a communication interface ID, which can be used to characterize the type of the communication interface. The communication interface location may be the location of the connection device where the communication interface is located, such as a first interface location, a second interface location, etc., which can be used to characterize the type of the communication interface.

[0049] S102. Determine a target firmware upgrade path based on the interface information.

[0050] In this embodiment, the firmware upgrade path includes a Display Data Channel (DDC channel), an Auxiliary channel (AUX channel), or a Universal Serial Bus channel (USB channel). For example, for an HDMI interface, the DDC channel can be selected as the firmware upgrade path; for a DisplayPort (DP) interface, the AUX channel can be selected as the firmware upgrade path; for a Type-C interface, the USB channel can be selected as the firmware upgrade path.

[0051] In this embodiment, the corresponding relationship between the interface information and the firmware upgrade path can be preset, so that the target firmware upgrade path corresponding to the target display can be determined through the interface information.

[0052] S103. Transmit the firmware upgrade package corresponding to the firmware upgrade instruction along the target firmware upgrade path to the target display, so that the target display completes the firmware upgrade.

[0053] In some embodiments, when sending or after sending a firmware upgrade instruction to a connection device, the electronic device may send the firmware upgrade package corresponding to the firmware upgrade instruction to the connection device at the same time.

[0054] In some embodiments, after determining the target firmware upgrade path, the connection device may send a request to the electronic device to obtain the firmware upgrade package corresponding to the firmware upgrade instruction.

[0055] In this embodiment, transmitting the firmware upgrade package corresponding to the firmware upgrade instruction along the target firmware upgrade path to the target display may be to perform protocol conversion on the firmware upgrade package according to the transmission protocol of the target firmware upgrade path, and then burn the protocol-converted firmware upgrade package along the target firmware upgrade path to the target display.

[0056] Specifically, after the connection device determines the target firmware upgrade path, it can determine the transmission protocol corresponding to the target firmware upgrade path, and then perform corresponding protocol conversion on the firmware upgrade package corresponding to the firmware upgrade instruction, so that the protocol-converted firmware upgrade package can be successfully transmitted to the target display through the target firmware upgrade path. For example, if the target firmware upgrade path is the DDC channel, since the DDC channel does not support USB-C protocol format data, the protocol format of the firmware upgrade package can be converted to the DDC protocol format, and special mapping or translation can be performed in specific fields to identify the firmware upgrade, so that the firmware upgrade package can be transmitted to the target display through the DDC channel. If the target firmware upgrade path is the AUX channel, since the AUX channel supports USB-C protocol format data, the protocol conversion of the firmware upgrade package does not need to be performed, and the firmware upgrade package can be directly transmitted to the target display through the AUX channel to achieve the passthrough effect. If the target firmware upgrade path is the USB channel, since the USB channel supports USB-C protocol format data, the protocol conversion of the firmware upgrade package does not need to be performed, and the firmware upgrade package can be directly transmitted to the target display through the USB channel to achieve the passthrough effect.

[0057] The firmware upgrade method provided by the embodiment of the present application detects a firmware upgrade instruction received from an electronic device, obtains interface information of a communication interface to which a target display is connected; determines a target firmware upgrade path based on the interface information; and transmits a firmware upgrade package corresponding to the firmware upgrade instruction along the target firmware upgrade path to the target display, so that the target display completes firmware upgrade; in this way, when the target display is connected to the electronic device through the connection device, the target firmware upgrade path and protocol adaptation can be performed in the connection device, so that the firmware upgrade package corresponding to the firmware upgrade instruction can be correctly transmitted to the target display, and the target display can complete firmware upgrade even when it is not directly connected to the electronic device.

[0058] In an optional embodiment, step S102, determining the target firmware upgrade path based on the interface information includes:

[0059] Determining the target firmware upgrade path based on the communication interface type in the interface information; or determining the target firmware upgrade path based on the communication interface identifier in the interface information; or determining the target firmware upgrade path based on the communication interface location in the interface information.

[0060] In this embodiment, the interface information includes a communication interface type, a communication interface identifier, and a communication interface location. The communication interface type, the communication interface identifier, and the communication interface location can all indicate the transmission protocol supported by the communication interface to which the target display is connected, so that the target firmware upgrade path can be determined based on the communication interface type or the communication interface identifier or the communication interface location in the interface information.

[0061] In some embodiments, when determining a target firmware upgrade path based on the communication interface identifier in the interface information, a correspondence between the communication interface identifier and the firmware upgrade path can be preset, so that based on the communication interface identifier in the interface information, the target firmware upgrade path corresponding to the communication interface can be determined. For example, if the communication interface identifier is 1, select the display data channel between the communication interfaces of the connection device and the target display as the firmware upgrade path; if the communication interface identifier is 2, select the auxiliary channel between the communication interfaces of the connection device and the target display as the firmware upgrade path; if the communication interface identifier is 3, select the universal serial bus channel between the communication interfaces of the connection device and the target display as the firmware upgrade path.

[0062] In some embodiments, when determining a target firmware upgrade path based on the communication interface location in the communication interface information, a correspondence between the communication interface location and the firmware upgrade path can be preset, so that based on the communication interface location in the interface information, the target firmware upgrade path corresponding to the communication interface can be determined. For example, if the communication interface location is the first interface location of the connection device, select the display data channel between the communication interfaces of the connection device and the target display as the firmware upgrade path; if the communication interface location is the second interface location of the connection device, select the auxiliary channel between the communication interfaces of the connection device and the target display as the firmware upgrade path; if the communication interface location is the third interface location of the connection device, select the universal serial bus channel between the communication interfaces of the connection device and the target display as the firmware upgrade path.

[0063] In this embodiment, by determining the target firmware upgrade path based on the communication interface type in the interface information; or based on the communication interface identifier in the interface information; or based on the communication interface location in the interface information, the firmware upgrade path through which the firmware upgrade package corresponding to the firmware upgrade instruction can pass can be quickly determined.

[0064] In an alternative embodiment, determining the target firmware upgrade path based on the communication interface type in the interface information includes at least one of the following:

[0065] If the communication interface type is a high-definition multimedia interface, select the display data channel between the communication interfaces of the connection device and the target display as the firmware upgrade path; if the communication interface type is a display interface, select the auxiliary channel between the communication interfaces of the connection device and the target display as the firmware upgrade path.

[0066] In this embodiment, the corresponding relationship between the communication interface type and the firmware upgrade path can be preset based on the flashing method supported by the display. For example, when the communication interface type is an HDMI interface, the corresponding firmware upgrade path is the DDC channel; when the communication interface type is a DP interface, since the corresponding firmware upgrade path for the DP interface is the AUX channel; when the communication interface type is a USB Type-C interface, the corresponding firmware upgrade path is the USB channel. Then, based on the interface information of the communication interface connected to the target display, the type of the communication interface connected to the target display can be determined, and thus the corresponding firmware upgrade path can be selected as the target firmware upgrade path.

[0067] In this embodiment, if the communication interface type is a High-Definition Multimedia Interface, the DDC channel between the connection device and the communication interface of the target display is selected as the firmware upgrade path; if the communication interface type is a DisplayPort interface, the auxiliary channel between the connection device and the communication interface of the target display is selected as the firmware upgrade path; if the communication interface type is a USB Type-C interface, the USB channel between the connection device and the communication interface of the target display is selected as the firmware upgrade path; in this way, the video / audio signal interference between the connection device and the communication interface of the target display can be bypassed, and the firmware upgrade package can be transmitted through a specific channel, so that the firmware upgrade package can be successfully sent to the target display.

[0068] In an alternative embodiment, step S103, transmitting the firmware upgrade package corresponding to the firmware upgrade instruction along the target firmware upgrade path to the target display, includes at least one of the following:

[0069] If the communication interface type is a High-Definition Multimedia Interface or a DisplayPort interface, the firmware upgrade package corresponding to the firmware upgrade instruction is flashed to the display control chip of the target display through the main control chip of the connection device; if the communication interface type is a Type-C interface, the firmware upgrade package corresponding to the firmware upgrade instruction is flashed to the storage area of the target display through the Universal Serial Bus hub of the connection device.

[0070] In this embodiment, as Figure 3 shown, if the communication interface type is a High-Definition Multimedia Interface or a DisplayPort interface, the firmware upgrade package corresponding to the firmware upgrade instruction can be flashed to the display control chip of the target display through the main control chip (SOC) of the connection device. For example, if the communication interface type connected to Display 1 is an HDMI interface, the firmware upgrade package corresponding to Display 1 can be flashed to the display control chip (Scaler1) of Display 1 through the SOC of the docking station. If the communication interface type connected to Display 2 is a DP interface, the firmware upgrade package corresponding to Display 2 can be flashed to the display control chip (Scaler2) of Display 2 through the SOC of the docking station.

[0071] AsFigure 3 As shown, if the communication interface type is a USB Type-C interface or a Thunderbolt 4 (TBT4) interface, the firmware upgrade package corresponding to the firmware upgrade instruction can be burned into the storage area of the target display through the universal serial bus hub (USB HUB) of the connection device. For example, if the communication interface type connected to the display is a USB Type-C interface or a TBT4 interface, the firmware upgrade package corresponding to Display 3 can be burned into the storage area (USB HUB) of Display 3 through the USB HUB of the docking station, and the display control chip (Scaler3) of Display 3 can obtain the firmware upgrade package from the storage area of Display 3.

[0072] It should be noted that Figure 3 only a notebook is taken as the electronic device and the docking station is taken as the connection device for illustration, but it is not a limitation on the electronic device and the connection device.

[0073] In this embodiment, if the communication interface type is a high-definition multimedia interface or a display interface, the firmware upgrade package corresponding to the firmware upgrade instruction is burned into the display control chip of the target display through the main control chip of the connection device; if the communication interface type is a Type-C interface, the firmware upgrade package corresponding to the firmware upgrade instruction is burned into the storage area of the target display through the universal serial bus hub of the connection device; in this way, the characteristics of the connection device can be fully utilized, and different firmware can be used to forward signals of different protocols, so as to quickly and accurately forward the firmware upgrade package to the target display.

[0074] In an optional embodiment, step S103, transmitting the firmware upgrade package corresponding to the firmware upgrade instruction along the firmware upgrade path to the target display, includes:

[0075] Based on the priority of the firmware upgrade path, the firmware upgrade package corresponding to the firmware upgrade instruction is transmitted to each target display through a time-sharing upgrade process.

[0076] In this embodiment, there are multiple target displays. Since the firmware upgrade package corresponding to each display needs to be sent to the corresponding target display, when the connection device sends multiple firmware upgrade packages, it can first determine the priority of the firmware upgrade path, and then send the firmware upgrade package corresponding to each target display to the corresponding target display according to the determined priority.

[0077] For example, the DDC channel has the first priority, the AUX channel has the second priority, and the USB channel has the third priority. When it is necessary to send the first firmware upgrade package, the second firmware upgrade, and the third firmware upgrade package through the DDC channel, the AUX channel, and the USB channel respectively, the first firmware upgrade package can be preferentially sent through the DDC channel, then the second firmware package can be sent through the AUX channel, and finally the third firmware upgrade package can be sent through the USB channel, so as to implement the time-sharing upgrade process based on the priority of the firmware upgrade path.

[0078] In this embodiment, based on the priority of the firmware upgrade path, the firmware upgrade package corresponding to the firmware upgrade instruction is transmitted to each target display through the time-sharing upgrade process; in this way, the resources of the connection device can be scheduled in a time-sharing manner to perform firmware upgrades on multiple target displays, ensuring that when multiple target displays perform firmware upgrades simultaneously, the resources of the connection device are sufficient and the upgrade interruption will not occur.

[0079] In an alternative embodiment, step S103, transmitting the firmware upgrade package corresponding to the firmware upgrade instruction along the target firmware upgrade path to the target display, includes:

[0080] If the communication interface type is a Type-C interface, the firmware upgrade package corresponding to the firmware upgrade instruction is transmitted to the universal serial bus hub of the intermediate display through the universal serial bus hub of the connection device, so as to burn the firmware upgrade package corresponding to the firmware upgrade instruction into the storage area of the target display through the universal serial bus hub of the intermediate display; the target display is connected to the connection device through the intermediate display, and the Type-C interface of the target display is connected to the Type-C interface of the intermediate display.

[0081] In this embodiment, the connection device is connected to the target display through the intermediate display. The intermediate display connects the USB Type-C interface of the connection device, and the target display connects the USB Type-C interface of the intermediate display. Then, when performing a firmware upgrade on the target display, the firmware upgrade package corresponding to the firmware upgrade instruction can be transmitted to the universal serial bus hub of the intermediate display through the universal serial bus hub of the connection device, so as to burn the firmware upgrade package corresponding to the firmware upgrade instruction into the storage area of the target display through the universal serial bus hub of the intermediate display.

[0082] In this embodiment, if the communication interface type is a USB Type-C interface, the firmware upgrade package corresponding to the firmware upgrade instruction is transmitted to the universal serial bus hub of the intermediate display through the universal serial bus hub of the connection device, so as to burn the firmware upgrade package corresponding to the firmware upgrade instruction into the storage area of the target display through the universal serial bus hub of the intermediate display; the target display is connected to the connection device through the intermediate display, and the USB Type-C interface of the target display is connected to the USB Type-C interface of the intermediate display; thus, when the connection device is connected to the target display through the intermediate display, when the USB Type-C interface of the intermediate display is connected to the connection device and the USB Type-C interface of the target display is connected to the intermediate display, the firmware upgrade of the target display can still be realized.

[0083] In an alternative embodiment, before obtaining the interface information of the communication interface to which the target display is connected in step S101, the firmware upgrade method further includes:

[0084] Identifying the extended display identification data in the firmware upgrade package corresponding to the firmware upgrade instruction; obtaining the extended display identification data of each display connected to the connection device; and determining the target display based on the extended display identification data in the firmware upgrade package and the extended display identification data of each display.

[0085] In this embodiment, the connection device can read the extended display identification data (EDID) of each connected display and then send the EDID to the electronic device. The electronic device can insert the EDID information into the firmware upgrade package. When the connection device obtains the firmware upgrade package corresponding to the firmware upgrade instruction, it can identify the EDID information in the firmware upgrade package and then match the EDIDs of each display to identify the target display.

[0086] Specifically, the connection device is connected to the electronic device through the USB-C interface and communicates with the display using the USB-C display protocol. These protocols can provide information about the number and characteristics of the connected displays. The target display can also be identified by querying the PID / VID in the USB protocol defined in the firmware upgrade package and then matching the PID / VID of each display.

[0087] Specifically, the connection device is connected to the electronic device through the USB-C interface and communicates with the display using the multi-stream transmission protocol of DP. These protocols can provide information about the number and characteristics of the connected displays. The target display can also be identified by querying the display characteristic value PIN in the USB protocol defined in the firmware upgrade package and then matching the PIN of each display.

[0088] In this embodiment, identify the extended display identification data in the firmware upgrade package corresponding to the firmware upgrade instruction; obtain the extended display identification data of each display connected to the connection device; based on the extended display identification data in the firmware upgrade package and the extended display identification data of each display, determine the target display; in this way, the target display to be upgraded can be accurately identified.

[0089] The embodiment of the present application also provides a connection device, as Figure 4 shown, including:

[0090] A processor 41, configured to detect a firmware upgrade instruction received from an electronic device, obtain interface information of a communication interface to which the target display is connected; determine a target firmware upgrade path based on the interface information; and transmit the firmware upgrade package corresponding to the firmware upgrade instruction along the target firmware upgrade path to the target display, so that the target display completes the firmware upgrade.

[0091] The connection device provided by the embodiment of the present application detects a firmware upgrade instruction received from an electronic device, obtains interface information of a communication interface to which the target display is connected; determines a target firmware upgrade path based on the interface information; and transmits the firmware upgrade package corresponding to the firmware upgrade instruction along the target firmware upgrade path to the target display, so that the target display completes the firmware upgrade; in this way, when the target display is connected to the electronic device through the connection device, the target firmware upgrade path and protocol adaptation can be performed in the connection device, so that the firmware upgrade package corresponding to the firmware upgrade instruction can be correctly transmitted to the target display, enabling the target display to complete the firmware upgrade even when it is not directly connected to the electronic device.

[0092] In an optional embodiment, as Figure 5 shown, the connection device further includes:

[0093] A main control chip 42, configured to if the communication interface type is a high-definition multimedia interface or a display interface, the processor 41 burns the firmware upgrade package corresponding to the firmware upgrade instruction to the display control chip of the target display through the main control chip 42;

[0094] A universal serial bus hub 43, configured to if the communication interface type is a Type-C interface, the processor 41 burns the firmware upgrade package corresponding to the firmware upgrade instruction to the storage area of the target display through the universal serial bus hub 43.
