[0040] An embodiment of the present invention provides a reverse touch control method for a touch screen device. This method converts a user's touch operation on a touch display screen into a first control signal capable of controlling a display control device via a controlled terminal. The display control device then generates a simulated contact operation based on the first control signal to simulate control of the display control device. Based on this principle, reverse touch control of a DP-OUT device from a DP-IN device is achieved. The reverse touch control method provided by the present invention can achieve reverse touch control of a DP-OUT device using the display screen of the DP-IN device without the need for additional communication hardware.

[0041] The concepts of the present invention are explained below:

[0042] DP: DisplayPort, a digital display interface, is mainly used to connect computers to display devices such as monitors, projectors or TVs. The signal it transmits is usually called a DisplayPort signal;

[0043] DP IN device: The DP IN device is the receiving end of the DisplayPort signal, usually referring to display devices such as monitors, projectors, or TVs. These devices have a DisplayPort input interface for receiving video and audio signals from the DP OUT device and displaying them on the screen;

[0044] DP OUT device: The DP OUT device is the output source of the DisplayPort signal. It can be a computer, laptop, smartphone, game console, or other video signal generating device. This device has a DisplayPort output interface for transmitting video and audio signals to another device through a DisplayPort cable.

[0045] Android: An operating system. An Android device is an electronic device that is loaded with the Android system.

[0046] USB: Universal Serial Bus, the Universal Serial Bus;

[0047] USB HAL layer: Hardware Abstraction Layer, the hardware abstraction layer, an abstraction layer between the operating system or application and the USB hardware, which provides a set of standardized interfaces, enabling upper-layer software to interact with the USB hardware through these interfaces without caring about the specific hardware implementation details;

[0048] HID: Human Interface Device, the human-computer interaction device, referring to a device designed to interact with human users to control a computer or other electronic devices;

[0049] handler processor: mainly responsible for managing data from external input devices such as keyboards, mice, touchscreens, etc., and passing this data to the corresponding device drivers, thereby realizing the interaction between the user and the system;

[0050] Type-C: a connection standard for an interface.

[0051] The following further elaborates on the control method of the embodiments of the present invention based on the accompanying drawings.

[0052] Refer to Figures 1 to 3 , Figure 1 , which is a flowchart of a reverse touch method for a touch screen device provided by the embodiments of the present invention, Figure 2 , which is a structural schematic diagram of a dual-end touch system provided by an embodiment of the present invention, Figure 3 is a schematic diagram of the data transmission direction of a touch screen device provided by an embodiment of the present invention. The reverse touch method of this touch screen device is applied to a dual-end touch system. The dual-end touch system includes a display control device and a controlled terminal communicatively connected thereto. The controlled terminal is provided with a touch display screen. The method includes but is not limited to the following steps:

[0053] Step S100, in response to a first contact operation on the touch display screen, the controlled terminal generates a first contact signal and converts the first contact signal into a first control signal capable of controlling the display control device according to a preset format;

[0054] Step S200, transmit the first control signal to the display control device. The display control device generates an analog contact operation according to the first control signal and performs corresponding actions according to the analog contact operation.

[0055] It should be noted that in the embodiment of the present invention, the DP OUT device is a display control device, the DP IN device is a controlled terminal, and a touch screen is provided on the DP IN device, so that the DP IN device itself has touch functionality. However, since devices connected via DisplayPort only support transmission of corresponding data formats, the touch screen of the DP IN device, such as the I2C screen, generates touch-related signals that can only be used in the DP IN device itself and cannot be transmitted back to the DP OUT device via the DisplayPort port. Therefore, in step S100, the embodiment of the present invention first converts the first contact signal generated by the user's operation on the touch screen of the DP IN device into a first control signal according to a preset conversion format. The first control signal is a simulation of the DP OUT control device. For example, when the DP OUT device is a computer, the first control signal is a simulation of the control signal generated by peripherals such as a keyboard and mouse when operating the computer. Furthermore, in step S200, after the first control signal is generated, it conforms to the information transmission format of DisplayPort, so the DPIN device can transmit the first control signal back to the DP OUT device through the DisplayPort port. After the DP OUT device receives the first control signal, it can parse the first control signal into a series of touch screen operations on the DP OUT device and execute them.

[0056] It should be noted that in steps S100 to S200, this embodiment of the present invention can transmit touch operations on the DP IN device back to the DP OUT device, and can also restore the corresponding touch operations on the DP OUT device. This functionality only requires the DP IN device to convert the touch operation signals into signals capable of controlling the DP OUT device according to the corresponding format, without the need for additional hardware.

[0057] In addition, in one embodiment, referring to Figure 4 ,exist Figure 1 Before step S100 in the illustrated embodiment, the following steps are also included but not limited to:

[0058] Step S101: The display control device accesses the controlled terminal and sends a broadcast event to the controlled terminal, wherein the broadcast event includes audio and video information and counter-control information;

[0059] Step S102: The controlled terminal displays audio and video information, and switches the USB mode of the controlled terminal to device mode according to the counter-control information;

[0060] Step S103: After the display control device recognizes that the controlled terminal has switched to the device mode, the display control device enumerates the controlled terminal as a HID device.

[0061] It should be noted that in one embodiment of the present invention, in steps S101 to S103, the controlled terminal, i.e., the DPIN device, is an Android device. When the DP OUT device is connected to the DP IN device, the Android layer of the DP IN device pops up whether to enable the DP IN function through the event reported by the driver. If the user needs to use the DP IN function, then the Android layer will display the audio and video information of the source device transmitted by the DP OUT on the screen of the DP IN device. At the same time, after the DP OUT device is connected to the DP IN device, it will broadcast the corresponding reverse control information to the DP IN device to remind the DP IN device to turn on the reverse control mode. After the USB Hal layer of the DPIN device detects the broadcast event of the DP OUT device being connected, it will also switch the USB mode to Device. At the same time, the DP OUT device enumerates the connected DP IN device as a HID device that supports the HID protocol and has a standard touch screen. At this time, the DP IN device will be regarded as a human-computer interaction input device in the control module of the DP OUT device. At this time, the DP IN device can convert the first contact signal formed by the touch operation into a first control signal.

[0062] In addition, in one embodiment, referring to Figure 4 , before Figure 1 the steps of the embodiment shown, the following steps are also included but not limited to:

[0063] Step S104, the USB driver of the controlled terminal listens for the first contact operation on the touch display screen through the Handler processor.

[0064] It should be noted that after the DP IN device that supports the HID protocol is enumerated on the DP OUT device, the preliminary preparation for the DP IN device to implement the reverse control function has been completed. Subsequently, the DP IN device can listen for the user's touch behavior on the DP IN device through the preliminary handler processor of the device's Android system.

[0065] In addition, in one embodiment, referring to Figure 4 , the display control device and the controlled terminal are communicatively connected through a Type-C interface. The communication modes of the display control device and the controlled terminal include a one-way communication mode and a reverse control communication mode. Before Figure 1 the steps of the embodiment shown, the following steps are also included but not limited to:

[0066] Before step S1011, where the display control device accesses the controlled terminal and sends a broadcast event to the controlled terminal, the following steps are included:

[0067] Step S1012: After the controlled terminal recognizes the access of the controlled terminal, the controlled terminal configures the differential signal lines of the Type-C interface to support DP communication and waits for the selection of the communication mode;

[0068] Step S1013: In response to the selection of the reverse control communication mode, the display control device sends a broadcast event to the controlled terminal;

[0069] Step S1014: In response to the selection of the one-way communication mode, the display control device only sends audio and video information to the controlled terminal.

[0070] It should be noted that in steps S1011 to S1014, it can be understood that after the DP IN device is connected to the DP OUT device, in addition to the reverse control function of the DP IN device on the DP OUT device, the normal forward control mode between the DP OUT device and the DP IN can also be realized. In this mode, the DP IN device cannot reverse control the DP OUT device. Specifically, when the DP OUT device is connected, after the underlying driver of the DP IN device recognizes the DP signal input by the DP OUT device and completes the training, it will report to the Android layer and switch the DPDM differential signal line in the Type-C to the USB port supporting DP. The Android layer pops up whether to enable the DP IN function through the event reported by the driver. At this time, the user can select whether to enable the reverse control mode through the mode selection function provided by the DPOUT device. When the user selects to enable the reverse communication mode, steps S103 to S104 of the above embodiment are executed; if the one-way control mode is selected, the DP OUT will directly send audio and video signals to the DPIN device and does not start the corresponding reverse control process.

[0071] In addition, in an embodiment, after step S1014 of the above embodiment, it further includes but is not limited to the following steps:

[0072] Step S240: When the display control device and the controlled terminal are in the one-way communication mode, the display control device generates a virtual interface on the controlled terminal, and the controlled terminal generates a virtual cursor to control the virtual interface, where the virtual cursor can be controlled through the touch display screen.

[0073] It should be noted that when the user selects the one-way communication mode in the above-mentioned aspect embodiments, at this time, the DP IN device and the DP OUT device are controlled separately, usually the DP device. However, in one embodiment, there is such a situation that the user needs to operate the content on the interface of the DP OUT transmission on the DP IN, and at the same time needs to adjust the background program of the DP OUT device. At this time, the DP OUT device transmits the required operation interface to the DP IN device, and the DP IN device generates a virtual cursor to operate the virtual interface. Since the virtual cursor can only control the virtual interface, the separate control of the DP IN device and the DP OUT device is realized.

[0074] In addition, in one embodiment, referring to Figure 5 , in Figure 1 the step S100 of the embodiment shown, it further includes but is not limited to the following steps:

[0075] Step S110, in response to a first contact operation on the touch display screen, the USB function driver of the controlled terminal records the touch information in the contact operation;

[0076] Step S120, the controlled terminal generates a first control signal in HID format according to the touch information.

[0077] It should be noted that in steps S110 to S120, in the embodiments of the present invention, when the user clicks or drags the touch screen of the DPIN device, the USB function driver records information such as its coordinates, trajectory, and touch pressure after monitoring the INPUT event, and converts the monitored INPUT event into a first control signal in HID format to simulate an external control device of the DP OUT device.

[0078] In addition, in one embodiment, referring to Figure 5 , in Figure 1 the step S200 of the embodiment shown, it further includes but is not limited to the following steps:

[0079] Step S210, the controlled terminal transmits the first control signal to the display control device, and the display control device analyzes the first control signal according to the format conversion rules of the HID protocol to obtain the touch information;

[0080] Step S220, the display control device generates a simulated contact operation according to the touch information and performs corresponding actions according to the simulated contact operation;

[0081] Step S230, when the display control device performs corresponding actions according to the simulated contact operation, it transmits the real-time picture to the real-time controlled terminal.

[0082] It should be noted that in steps S210 to S230, the touch data in HID format generated by the controlled terminal complies with the standard HID protocol. The DP OUT device end will parse it into specific touch behaviors, including information such as coordinates, trajectories, and touch pressures, in the USB HID format, so as to realize the touch operation on the screen and synchronous display. For users, it is like touching the screen in real time on the DP IN device, achieving the experience of dual-screen collaboration.

[0083] Referring to Figure 2 , on the second aspect, an embodiment of the present invention provides a dual-terminal touch system. The dual-terminal touch system includes a display control device and a controlled terminal communicatively connected thereto. The controlled terminal is provided with a touch display screen.

[0086] A memory 802, which can be implemented in forms such as a read-only memory (ROM), a static storage device, a dynamic storage device, or a random access memory (RAM). The memory 802 can store an operating system and other application programs. When implementing the technical solutions provided by the embodiments of this specification through software or firmware, the relevant program codes are stored in the memory 802 and are called by the processor 801 to execute the reverse touch method of the touch screen device in the embodiments of the present application;

[0087] An input / output interface 803, which is used to realize information input and output;

[0088] A communication interface 804, which is used to realize the communication interaction between this device and other devices, and can communicate through wired means (such as USB, network cable, etc.) or wireless means (such as mobile network, WIFI, Bluetooth, etc.);

[0089] The bus 805 transmits information among various components of the device (such as the processor 801, the memory 802, the input / output interface 803, and the communication interface 804).

[0090] Among them, the processor 801, the memory 802, the input / output interface 803, and the communication interface 804 are communicatively connected to each other inside the device through the bus 805.

[0091] The embodiment of the present application also provides a storage medium, which is a computer-readable storage medium. The storage medium stores a computer program, and when the computer program is executed by a processor, the reverse touch method of the above touch screen device is implemented.

[0092] As a non-transitory computer-readable storage medium, the memory can be used to store non-transitory software programs and non-transitory computer-executable programs. In addition, the memory may include high-speed random access memory, and may also include non-transitory memory, such as at least one magnetic disk storage device, a flash memory device, or other non-transitory solid-state storage devices. In some embodiments, the memory may optionally include a memory remotely disposed relative to the processor, and these remote memories can be connected to the processor through a network. Examples of the above network include but are not limited to the Internet, an enterprise intranet, a local area network, a mobile communication network, and combinations thereof. The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separated, and may be located in one place, or may be distributed to multiple network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of this embodiment.

[0093] The following is a specific embodiment of the present invention:

[0094] Referring to Figures 1 to 5 , the embodiment of the present invention provides a method for a DP IN device to reverse-touch a DP OUT device. When a DP OUT device (such as a mobile phone or a laptop) is connected, the screen of the DP OUT device can be synchronously displayed on the DP IN device in real time in the "mirror projection" mode. The present invention can send the touch events of the DP IN touch screen to the DP OUT device through the USB HID protocol to achieve reverse touch on the DP OUT device; when the DP OUT device switches to the "computer mode", the DP IN device can completely get rid of the touch of the DP IN device, and the two can independently complete their respective tasks. As Figure 3As shown in the figure, after the DP OUT device is connected and the underlying driver recognizes the input DP signal and completes the training, it will report to the Android layer and switch the DPDM differential signal line in the Type-C to the USB port supporting DP. The Android layer pops up whether to enable the DPIN function through the event reported by the driver. If the user needs to use the DPIN function, the Android layer will display the source device screen of the DP OUT on the screen of the DP IN device. At the same time, after the USB Hal layer receives the broadcast of the DP device connection, it will also switch the USB mode to Device. A standard touch screen device supporting the HID protocol can be enumerated on the DP OUT device. The function driver of USB registers an Input Handler through the Input subsystem of the kernel to monitor the touch events on the display screen. When clicking or dragging the touch screen at the DP IN device end, the USB function driver records information such as its coordinates and touch pressure after monitoring the INPUT event, and sends the coordinate information to the host controller of the DP OUT device in the form of touch data in the standard USB HID format when receiving the synchronization event. Since the format of the sent touch data conforms to the standard HID protocol, the DP OUT device end will parse it into TP events in the USB HID format to implement the touch operation on the screen. For the user, it is like touching the screen displayed on the DPIN device in real time to achieve the experience of dual-screen collaboration. Further, in the computer mode, the DP OUT device end outputs a virtual PC interface to the DP IN device, and the touch function at the DP IN end can be directly used for touch. At this time, the DP OUT device can completely switch the screen mirroring APP to the background, and the two work independently.
