[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0045] Most commercial display products and televisions on the market are controlled by remote controls and lack touch functionality. When the remote is lost or annotations are needed, operation is limited to physical buttons or a mouse. To simplify the design of commercial display products and televisions, most have eliminated physical buttons except for the power button. Mouse operation is also less convenient than touch control. Therefore, in scenarios requiring touch functionality, a retrofitted touch bezel can be used to enable touch control on the television. Retrofitted touch bezels typically employ infrared technology, using infrared light to detect the user's touch points on the screen, enabling single-point touch or simple writing.

[0046] Since the aforementioned commercial display products and televisions were not designed with touch functionality in mind, some touch functions, such as "back," cannot be implemented through a retrofitted touch frame device. Users still need to use a remote control when they need to return to the previous menu or screen.

[0047] To achieve some touch functions that are not possible with existing technologies, this application provides a touch frame device, a touch display system, and an interface return method, which are described in detail below:

[0048] See Figure 1 The size of the aftermarket touch frame device should be equal to or slightly larger than the size of the commercial display product so that the aftermarket touch frame device can completely cover the commercial display product, thereby achieving full-screen touch control.

[0049] The touch frame device provided in this application embodiment can be found in [reference]. Figure 2 As shown, it includes: an infrared module 101, a control module 102, a memory module 103, and a selection connection module 104;

[0050] Infrared module 101 is connected to control module 102, control module 102 is connected to selection connection module 104, and memory module 103 is connected to selection connection module 104;

[0051] Infrared module 101 is used to collect the user's touch position;

[0052] The memory module 103 is used to store preset software, wherein the preset software includes software that returns to the floating window;

[0053] The control module 102 is used to transmit the preset software in the memory module 103 to the display device through the selection connection module 104, so that the display device can install the return floating window software and display the return floating window; acquire the touch position collected by the infrared module 101, generate touch commands according to the touch position; and send the touch commands to the display device through the selection connection module 104, so that the display device can perform the interface return operation when the touch command is the touch return floating window.

[0054] The infrared module 101 uses infrared technology to collect the user's touch position. It consists of infrared emitting and receiving elements mounted on the outer frame of the touch frame device. An infrared detection network is formed on the surface of the touch frame device. Touching the surface of the touch frame device can change the infrared light on the touch point. The changed infrared light is then converted into the coordinate position of the touch.

[0055] The connection module 104 is controlled by the control module 102. It can either output preset software stored in the memory module 103 to the display device, or output touch commands generated based on the touch position collected by the infrared module 101 to the display device.

[0056] The preset software stored in memory module 103 includes software for returning to the floating window. In one example, control module 102 can be an MCU (Microcontroller Unit). The display device can connect to the touch frame device via a USB (Universal Serial Bus) interface. The touch frame device can transmit data with the display device via the USB interface, and the display device can also power the touch frame device via the USB interface. In other possible embodiments, the touch frame device can also be powered by an internal power module connected to AC power. After the touch frame device and the display device are connected and powered on for the first time, as shown in Figure 3(a), the control module 102 controls the selection connection module 104 to transfer the preset software in the memory module 103 to the display device. The display device receives the preset software via USB connection and installs it. After successful installation, the display returns to the floating window and sends a message of successful installation to the touch frame device. After receiving the message of successful installation, the control module 102 controls the selection connection module 104 to transmit the information in the control module 102 to the display device, as shown in Figure 3(b). The control module 102 generates touch commands based on the touch position collected by the infrared module 101 and sends the touch commands to the display device through the selection connection module. When the touch position is the location of the return floating window, the display device performs the interface return operation.

[0057] After installing the "Return to Floating Window" software on the display device, users can return to the previous screen by clicking the floating window's location, eliminating the need for a remote control and making operation more convenient. Specifically, when the user clicks the floating window's location, the infrared module 101 captures the user's touch position, the control module 102 generates a touch command including that touch position, and sends it to the display device via the connection module 104. Upon receiving the touch command, the display device detects that it represents a click operation on the floating window and executes the interface return operation.

[0058] In one possible implementation, the control module 102 is specifically configured to: in response to the touch frame device accessing the display device, control the selection connection module 104 to transmit the preset software in the memory module 103 to the display device, so that the display device installs the return floating window software and displays the return floating window.

[0059] After the touch frame device and the display device are connected and powered on for the first time, as shown in Figure 3(a), the control module 102 controls the selection connection module 104 to transfer the preset software in the memory module 103 to the display device. The display device receives and installs the preset software via USB connection. Figure 4 After successful installation, a return floating window will be displayed.

[0060] Install the return floating window software on the display device and display the return floating window. When the touch position is at the position of the return floating window, the display device performs the interface return operation, and there is no need to use the remote control.

[0061] In one possible implementation, the control module 102 is specifically configured to: in response to receiving an installation success message from the display device indicating that the software for returning to the floating window has been successfully installed, control the selection and connection module 104 to send the touch command to the display device, so that the display device performs an interface return operation when the touch command is to return to the floating window.

[0062] Referring to Figure 3(b), after receiving the installation success message, the control module 102 controls the selection and connection module 104 to send the touch command generated by the control module 102 based on the touch position collected by the infrared module 101 to the display device. When the touch position is the location of the return floating window, the display device performs the interface return operation.

[0063] In one possible implementation, the preset software also includes at least one of the following: a mute floating window software, a signal source floating window software, and an application favorites floating window software.

[0064] The installation methods for the silent floating window software, signal source floating window software, and application favorites floating window software can be referred to the installation method for the return floating window software, and will not be repeated here. See also Figure 5 After installing the mute floating window software, a mute floating window will appear on the display device. Touching the location of the mute floating window will mute the device, and touching the location again will unmute it. After installing the signal source floating window software, a signal source floating window will appear on the display device. Touching the location of the signal source floating window will pop up a signal source pop-up window, and touching the corresponding signal source pop-up window will switch to the signal source selection interface. After installing the application favorites floating window software, a favorites floating window will appear on the display device. Touching the favorites floating window will jump to the application favorites interface.

[0065] The floating window function can be selected according to user needs to achieve some touch functions that are not possible with existing technologies, making user operation more convenient. Each floating window can be designed in any shape and can be moved or hidden by touch, thereby reducing obstruction of the user's view.

[0066] This application provides a touch display system, including: a touch frame device 201 and a display device 202;

[0067] The touch frame device 201 is used to transmit preset software to a display device, wherein the preset software includes software that returns to the floating window;

[0068] Display device 202 is used to install the return floating window software and display the return floating window;

[0069] The touch frame device 201 is also used to collect the user's touch position, generate touch commands based on the touch position, and send the touch commands to the display device 202;

[0070] The display device 202 is also used to perform an interface return operation when the touch command is a touch return floating window.

[0071] See Figure 6 The display device includes at least one USB interface. The touch frame device can be connected to the USB interface of the display device via a USB Type-A plug (USB Type-A is the most common USB interface, which is flat and rectangular in shape. The pins inside the interface are asymmetrical and can only be inserted in one direction. It is usually used on one side of host devices such as computers, game consoles, and TVs). The touch frame device can be a USB driverless device, which can realize touch function without installing drivers.

[0072] In one example, the default software is a return floating window software. The display device 202 supplies power to the touch frame device 201 via USB connection. After the touch frame device 201 and the display device 202 are connected and powered on for the first time, the touch frame device 201 transmits the default software to the display device 202. The display device 202 receives the default software via USB connection and installs it. After successful installation, the return floating window is displayed and a message indicating successful installation is sent to the touch frame device 201. After receiving the message indicating successful installation from the display device 202, the touch frame device 201 collects the user's touch position and generates a touch command based on the touch position. The touch command is then sent to the display device 202. When the touch position is the location of the return floating window, the display device 202 performs an interface return operation.

[0073] Install the return floating window software on the display device 202 to return to the previous screen by touching the position of the return floating window, eliminating the need for a remote control and making the operation more convenient for users.

[0074] In one possible implementation, the display device 202 is further configured to: when the touch command is to drag back the floating window, move the floating window to the position where the touch command is dragged in the display interface.

[0075] See Figure 7 The floating window on the top left of the display device 202 is the floating window at the initial position, and the floating window on the top right of the display device 202 is the floating window at the final position. The floating window shown by the dotted line in the figure is the floating window in the drag path. During the dragging process, the floating window always moves with the touch position.

[0076] The floating window can be designed in any shape and can be moved or hidden via touch to avoid obstructing the user's view.

[0077] In one possible implementation, the touch frame device 201 includes: an infrared module 101, a control module 102, a memory module 103, and a selection connection module 104;

[0078] Infrared module 101 is connected to control module 102, control module 102 is connected to selection connection module 104, and memory module 103 is connected to selection connection module 104;

[0079] Infrared module 101 is used to collect the user's touch position;

[0080] The memory module 103 is used to store preset software, wherein the preset software includes software that returns to the floating window;

[0081] The control module 102 is used to transmit the preset software in the memory module 103 to the display device 202 using the selection connection module 104; acquire the touch position collected by the infrared module 101, generate touch commands based on the touch position; and send the touch commands to the display device 202 using the selection connection module 104.

[0082] In one example, the preset software stored in the memory module 103 is a return floating window software. The control module 102 can be an MCU. After the touch frame device 201 and the display device 202 are connected and powered on for the first time, the control module 102 controls the selection connection module 104 to transfer the preset software in the memory module 103 to the display device 202. The display device 202 receives the preset software via USB connection and installs it. After successful installation, it displays the return floating window and sends a message of successful installation to the touch frame device 201. After receiving the message of successful installation, the control module 102 controls the selection connection module 104 to send the touch command generated by the control module 102 based on the touch position collected by the infrared module 101 to the display device 202. When the touch position is the location of the return floating window, the display device 202 performs the interface return operation.

[0083] Install the return floating window software on the display device 202 to return to the previous screen by touching the position of the return floating window, eliminating the need for a remote control and making the operation more convenient for users.

[0084] In one possible implementation, the control module 102 is specifically configured to: in response to the touch frame device 201 accessing the display device 202, control the selection connection module 104 to transmit the preset software in the memory module 103 to the display device 202.

[0085] After the touch frame device 201 and the display device 202 are connected and powered on for the first time, the control module 102 controls the selection connection module 104 to transmit the preset software in the memory module 103 to the display device. The display device 202 receives the preset software via USB connection and installs it. After successful installation, the return floating window is displayed.

[0086] Install the return floating window software on the display device 202 and display the return floating window. When the touch position is the position of the return floating window, the display device 202 performs the interface return operation, and there is no need to use the remote control.

[0087] In one possible implementation, the display device 202 is further configured to: send an installation success message to the touch frame device 201 after the installation of the return floating window software is completed;

[0088] Specifically, the control module 102 is used to: in response to receiving a successful installation message, control the connection selection module 104 to send the touch command to the display device 202.

[0089] After receiving the installation success message, the control module 102 controls the selection and connection module 104 to send the touch command generated by the control module 102 based on the touch position collected by the infrared module 101 to the display device 202. When the touch position is the location of the return floating window, the display device 202 performs the interface return operation.

[0090] In one possible implementation, the preset software also includes at least one of the following: a mute floating window software, a signal source floating window software, and an application favorites floating window software.

[0091] The installation methods for the Mute Floating Window software, Signal Source Floating Window software, and App Favorites Floating Window software can be referenced from the installation method for the Return Floating Window software. After the Mute Floating Window software is installed on the display device, a Mute Floating Window will appear. Touching the Mute Floating Window will mute the display device, and touching it again will unmute it. After the Signal Source Floating Window software is installed on the display device, a Signal Source Floating Window will appear. Touching the Signal Source Floating Window will bring up a Signal Source pop-up window, and touching the corresponding Signal Source pop-up window will switch to the Signal Source selection interface. After the App Favorites Floating Window software is installed on the display device, a Favorites Floating Window will appear. Touching the Favorites Floating Window will redirect to the App Favorites interface.

[0092] The floating window function can be selected according to user needs to achieve some touch functions that are not possible with existing technologies, making user operation more convenient. Each floating window can be designed in any shape and can be moved or hidden by touch to avoid obstructing the user's view.

[0093] This application provides a method for returning to an interface, see [link to relevant documentation]. Figure 8 Applied to any touch frame device in this application, including:

[0094] S301, the preset software in the memory module is transmitted to the display device using the selection connection module, so that the display device can install the return floating window software and display the return floating window, wherein the preset software includes the return floating window software;

[0095] S302, Obtain the touch position collected by the infrared module, and generate touch commands based on the touch position;

[0096] S303 uses the selection connection module to send touch commands to the display device, so that the display device performs an interface return operation when the touch command is a touch return floating window.

[0097] After the touch frame device and display device are connected and powered on for the first time, the touch frame device uses the selection connection module to send the preset software stored in the memory module to the display device. The display device receives and installs the preset software. Upon successful installation, a return floating window is displayed, and an installation success message is sent to the touch frame device. After receiving the installation success message, the touch frame device uses the selection connection module to transmit touch commands to the display device. Specifically, the touch frame device generates touch commands based on the touch position collected by the infrared module and sends these commands to the display device through the selection connection module. When the display device receives a touch command indicating a click on the return floating window, the display device performs a return operation.

[0098] After installing the "Return to Floating Window" software on the display device, users can return to the previous screen by clicking the floating window's location, eliminating the need for a remote control and making operation more convenient. Specifically, when the user clicks the floating window's location, the infrared module 101 captures the user's touch position, the control module 102 generates a touch command including that touch position, and sends it to the display device via the connection module 104. Upon receiving the touch command, the display device detects that it represents a click operation on the floating window and executes the interface return operation.

[0099] In addition to the default floating window software, other software can be designed according to actual needs, such as a mute floating window software, a signal source floating window software, and an application favorites floating window software. The installation process of these software can be referred to the installation method of the default floating window software, and will not be repeated here. After the mute floating window software is installed on the display device, a mute floating window will be displayed. Touching the location of the mute floating window will mute the display device, and touching the location of the mute floating window again will unmute it. After the signal source floating window software is installed on the display device, a signal source floating window will be displayed. Touching the location of the signal source floating window will pop up a signal source pop-up window, and touching the corresponding signal source pop-up window will switch to the signal source selection interface. After the application favorites floating window software is installed on the display device, a favorites floating window will be displayed. Touching the favorites floating window will jump to the application favorites interface.

[0100] Install the return floating window software on the display device and display the return floating window. When the touch position is at the position of the return floating window, the display device performs the interface return operation, and there is no need to use the remote control.
