[0044] Description of Figure Numbers: DETAILED DESCRIPTION

[0045] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0046] In addition, the described features, structures or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure can be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, well-known methods, devices, implementations or operations are not shown or described in detail to avoid blurring various aspects of the present disclosure.

[0047] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0048] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.

[0049] It should also be noted that the terms "first," "second," and the like in the specification and claims of the present disclosure and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the present disclosure described herein can be implemented in an order other than that shown or described.

[0050] Figure 1 shows a schematic structural diagram of a dual-screen laptop computer in one embodiment. As shown in Figure 1, the dual-screen laptop computer may include: a central processing unit 10, a micro control unit 20, a main display screen (not shown), an operation panel (not shown) and a sub-display screen 30; wherein the sub-display screen 30 is arranged on the back of the main display screen or on the operation panel; the first output end of the central processing unit 10 is connected to the first input end of the micro control unit 20 through a preset interface, and the preset interface is any one of a mobile industry processor interface, a serial peripheral interface, and a universal serial bus interface; the output end of the micro control unit 20 is connected to the sub-display screen 30.

[0051] Assuming that a dual-screen laptop can be divided into sides A, B, C, and D, side A is the back of the main display, i.e., the side where the back cover of the main display is located; side B is the side where the main display is located; side C is the side where the operation panel is located; and side D is the back of the operation panel, i.e., the side where the bottom cover of the dual-screen laptop is located. In the disclosed embodiment, the secondary display 30 can be located on either side A or C of the dual-screen laptop.

[0052] Figure 2 shows a schematic diagram of the position of the secondary display screen 30 in Figure 1. As shown in Figure 2, the secondary display screen 30 is set on the A side of the dual-screen laptop computer. The embodiment of the present disclosure does not limit the size of the secondary display screen 30 and the specific position on the A side.

[0053] FIG3 illustrates another schematic diagram of the position of the secondary display screen 30 in FIG1 . As shown in FIG3 , the primary display screen 40 is located on the B side of the dual-screen laptop, while the secondary display screen 30 is located on the operating panel, i.e., on the C side of the dual-screen laptop. The present disclosure does not limit the size or specific position of the secondary display screen 30 on the C side. In some embodiments, when the secondary display screen 30 is located on the C side of the dual-screen laptop and is a touch screen, the secondary display screen 30 can be located in the position of a traditional touchpad, replacing the traditional touchpad and performing the corresponding functions of the traditional touchpad.

[0054] In some embodiments, if the secondary display screen 30 is an ink screen, the preset interface can be a serial peripheral interface (SPI) or a universal serial bus interface (USB), that is, the first output end of the central processing unit 10 is connected to the first input end of the micro control unit 20 through the SPI interface or the SUB interface, and the output end of the micro control unit 20 is connected to the ink screen.

[0055] FIG4 shows a schematic diagram of the structure of the microcontroller unit 20 in FIG1 . As shown in FIG4 , the microcontroller unit 20 has an SPI interface and a USB 2.0 interface at its input, and an SPI interface at its output. Thus, the microcontroller unit 20 can be connected to the central processing unit via the SPI interface or the USB 2.0 interface to achieve signal transmission between the microcontroller unit and the central processing unit. During implementation, a microcontroller unit with a larger flash memory capacity can be selected to support more data processing.

[0056] Referring back to Figure 1, in other embodiments, if the secondary display screen 30 is a color screen, the preset interface can be a mobile industry processor interface (MIPI), that is, the first output end of the central processing unit 10 is connected to the first input end of the micro control unit 20 through the MIPI interface, and the output end of the micro control unit 20 is connected to the color screen.

[0057] It is understandable that after the micro control unit 20 is connected to the central processing unit 10, the first application program interface (API) can be called from the central processing unit 10 to obtain the target data to be displayed through the first API interface, and output the target data to be displayed to the secondary display screen 30 for display.

[0058] During the implementation process, the target data to be displayed can be data corresponding to the user's customized APP, such as time, weather, meeting records, chat information, navigation information of materials, etc.

[0059] Since the micro control unit 20 has independent programming capability, the micro control unit 20 can also obtain data from the central processing unit 10 in other ways, and after processing the obtained data, output it to the secondary display screen 30 for display.

[0060] It should be noted that the secondary display screen in current dual-screen laptops is directly connected to the central processing unit through the EDP interface, resulting in poor scalability of the secondary display screen. At the same time, this solution has high requirements for the secondary display screen, such as requiring the secondary display screen to have an EDP interface, a high refresh rate and a large size.

[0061] The dual-screen laptop computer of the disclosed embodiment can control the display content of the secondary display screen 30 through the microcontroller unit 20, so that the display content of the secondary display screen 30 is not restricted by the display content of the primary display screen, thereby improving the scalability of the display content of the secondary display screen 30. Furthermore, this solution reduces the requirements for the secondary display screen 30, as the secondary display screen 30 does not need to have an EDP interface. Moreover, because the display content of the secondary display screen 30 is not restricted by the display content of the primary display screen, the secondary display screen 30 can adopt a smaller refresh rate and size.

[0062] Figure 5 shows a structural schematic diagram of a dual-screen laptop computer in another embodiment. As shown in Figure 5, the dual-screen laptop computer may further include: a first adapter device 50 and a screen cable (not marked); wherein, the input end of the first adapter device 50 is connected to the second output end of the central processing unit 10 through an extended display interface; and the output end of the first adapter device 50 is connected to the main display screen 40 through the screen cable.

[0063] In some embodiments, the first adapter device 50 may be an adapter interface having an EDP interface, one end of the adapter interface being connected to the central processor 10 via the EDP interface, and the other end being connected to the main display screen 40 via a screen cable.

[0064] Through the above design, the main display screen 40 can display the data output by the central processing unit 10, and the sub-display screen 30 can also display the data processed by the micro control unit 20, thereby realizing the dual-screen display of the dual-screen laptop computer.

[0065] Figure 6 shows a schematic diagram of the structure of another embodiment of a dual-screen laptop computer, applicable to a case where the secondary display screen is located behind the primary display screen. As shown in Figure 6 , the dual-screen laptop computer may further include a second adapter device 60 disposed within the hinge housing; wherein the second adapter device 60 is connected to the output of the first adapter device 50 via a display cable; and the output of the microcontroller unit 20 is connected to the secondary display screen 30 via the first adapter device 50, the display cable, and the second adapter device 60 in sequence.

[0066] The arrangement of the second adapter device 60 in the hinge box can be referred to Figure 7. As shown in Figure 7, a hinge box is arranged between the main display screen and the operation panel of the dual-screen laptop computer. One end of the second adapter device is connected to the screen cable, and the other end is connected to the secondary display screen through a flexible printed circuit (FPC).

[0067] During implementation, the first adapter 50 may be an adapter. FIG8 shows a schematic structural diagram of the first adapter 50 in FIG7 . As shown in FIG7 , the first adapter 50 is an adapter having an EDP interface and an SPI interface, and outputting signals via a screen line. Of course, the adapter may also have an EDP interface and a MIPI interface, and output signals via a screen line.

[0068] During the implementation process, the second adapter device 60 can be an adapter board. Figure 9 shows a structural schematic diagram of the second adapter device 60 in Figure 7. As shown in Figure 9, the second adapter device 60 is an adapter board, which has an input interface 601, an output interface 602 and a power sub-unit 603, wherein the input interface 601 is connected to the output end of the first adapter device through a screen line, the output interface 602 is connected to the secondary display screen through an FPC line, and the power sub-unit 603 is used to supply power to the secondary display screen.

[0069] The circuit design of the power subunit 603 can be referenced to FIG10 . As shown in FIG10 , the power subunit may include first to fifth capacitors C1 to C5, first to third diodes D1 to D3, an inductor L, a MOS transistor Q1, and a resistor R. The anode of the first diode D1, the cathode of the third diode D3, and the gate of the MOS transistor Q1 are all connected to the output interface 602. The power subunit can provide a 3.3V voltage for the secondary display screen.

[0070] It should be noted that the central processing unit 10, the micro control unit 20 and the first adapter device 50 are usually arranged on the motherboard. How to connect the micro control unit 20 with the secondary display screen 30 arranged on the A side of the dual-screen laptop computer becomes a difficult problem to solve.

[0071] In the disclosed embodiments, the design of the second adapter not only reduces the number of signal lines passing through the hinge box and prevents the cables from being squeezed by the hinge, but also provides power and multiple interfaces for the secondary display, facilitating the selection of a secondary display. The microcontroller unit is connected to the secondary display via the first adapter, the screen cable, and the second adapter, achieving a connection between the microcontroller unit and the secondary display located on the A side of the dual-screen laptop.

[0072] FIG11 shows a schematic diagram of the structure of a dual-screen notebook computer in another embodiment, which is applicable to the case where the secondary display screen is arranged on the operation panel. As shown in FIG11 , the first output terminal of the micro control unit 20 is connected to the secondary display screen 30 .

[0073] It is understandable that when the sub-display screen 30 is provided on the operation panel, the micro control unit 20 may be directly connected to the sub-display screen 30 to achieve signal transmission with the sub-display screen 30 .

[0074] In some embodiments, if the auxiliary display screen 30 is a touch screen, the second output terminal of the micro control unit 20 is connected to the input terminal of the central processing unit 10 , and the second input terminal of the micro control unit 20 is connected to the auxiliary display screen 30 .

[0075] It is understood that if the secondary display screen 30 is a touch screen, it can be placed in the position where a traditional touch screen is located and replace the traditional touchpad. In this case, the secondary display screen 30 needs to perform both touchpad and display functions. If the secondary display screen 30 is a touch screen, it can also be placed in the position where a traditional keyboard is located and replace the traditional keyboard. In this case, the secondary display screen 30 needs to perform both keyboard and display functions.

[0076] In order to realize the function of the touchpad or keyboard, the microcontroller unit 20 can call the second API interface corresponding to the touchpad to obtain the first data to be displayed corresponding to the touchpad (i.e., the touchpad interface) through the second API interface, or call the third API interface corresponding to the keyboard to obtain the second data to be displayed corresponding to the keyboard (i.e., the keyboard interface) through the third API interface, and output the first data to be displayed or the second data to be displayed to the secondary display screen 30 for display.

[0077] The secondary display screen 30 outputs the touch data generated by the user on the secondary display screen 30 to the microcontroller unit 20 through the USB interface. The microcontroller unit 20 then sends the touch data to the central processing unit 10 through the USB interface. The central processing unit 10 generates corresponding data to be displayed based on the touch data, and outputs the data to be displayed to the main display screen 40 through the EDP interface for display.

[0078] In order to realize the display function, the micro control unit 20 can obtain data from the central processor 10 through the MIPI interface, and output the obtained data through the MIPI interface to the secondary display screen 30 for display. The micro control unit 20 can also obtain data from the central processor 10 through the SPI interface or the USB interface, and output the obtained data through the SPI interface to the secondary display screen 30 for display.

[0079] In some embodiments, the dual-screen laptop computer may further include a function switching unit 70, which is connected to the third input terminal of the microcontroller unit 20, wherein the function switching unit is used to output a function switching signal to the microcontroller unit 20; the microcontroller unit 20 is used to control the secondary display screen 30 to realize the function of a touchpad or keyboard when the function switching signal is a first signal; when the function switching signal is a second signal, the first application programming interface corresponding to the target data to be displayed is called from the central processor 10 to obtain the target data to be displayed through the first application programming interface, and output the target data to be displayed to the secondary display screen 30 for display.

[0080] During the implementation process, the function switching unit 70 can be an embedded controller. The user can trigger the embedded controller to output the level signal of the General Purpose Input Output (GPIO) as a function switching signal through a hot key or a physical key. The microcontroller unit 20 switches the display function of the touch screen and the function of the touchpad according to the high and low level signals, or switches the display function of the touch screen and the function of the keyboard according to the high and low level signals.

[0081] Taking switching the display function of the touch screen and the function of the touchpad as an example, the microcontroller unit 20 can call the first API interface corresponding to the target data to be displayed from the central processor 10 when the level signal is high, so as to obtain the target data to be displayed through the first API interface, and output the target data to be displayed to the sub-display screen 30 for display, thereby realizing the display function of the touch screen; when the level signal is low, the sub-display screen 30 is controlled to realize the function of the touchpad.

[0082] FIG12 is a schematic diagram of a data flow for the dual-screen laptop computer shown in FIG11 . As shown in FIG12 , the embedded controller outputs a function switching signal to the microcontroller unit 20. When the function switching signal received by the microcontroller unit 20 is a first signal indicating a switch to the touchpad function, the microcontroller unit 20 calls a second API interface from the touchpad controller 80 to obtain first data to be displayed corresponding to the touchpad (i.e., the touchpad interface) through the second API interface, and outputs the first data to be displayed to the secondary display screen 30 for display. When a user touches the secondary display screen 30, touch data is generated on the secondary display screen 30. The secondary display screen 30 outputs the touch data to the microcontroller unit 20, which sends the touch data to the central processing unit 10. The central processing unit 10 generates data to be displayed corresponding to the touch data (e.g., data for manipulating the display screen of the main display screen 40), and outputs the data to be displayed to the main display screen 40 for display.

[0083] It should be noted that compared with the dual-screen laptop computer solution that uses two independent modules, namely the traditional touchpad and the secondary display screen, or the solution that uses two independent modules, namely the traditional keyboard and the secondary display screen, the embodiment of the present disclosure can realize multiple functions such as the touchpad, user-customized display content and handwriting input through a secondary display screen with a touch function, thereby realizing the switching of the secondary display screen function according to user needs.

[0084] FIG13 is a flow chart showing a method for controlling a dual-screen laptop computer according to an embodiment. As shown in FIG13 , a method for controlling a dual-screen laptop computer is provided. The method is described by taking the microcontroller unit in FIG1 as an example. The method may include the following steps:

[0085] Step 1301: calling a first application programming interface corresponding to target data to be displayed from a central processing unit to obtain the target data to be displayed through the first application programming interface;

[0086] Step 1302: Output the target data to be displayed to the secondary display screen for display.

[0087] During the implementation process, the target data to be displayed can be data corresponding to a customized APP, such as time, weather, meeting records, chat information, navigation information of data, etc.

[0088] The micro control unit can call the first API interface based on any one of a variety of protocols such as Hypertext Transfer Protocol (HTTP), Remote Procedure Call Protocol (RPC), Simple Object Access Protocol (SOAP), etc. The embodiment of the present disclosure does not limit the implementation method of calling the first API interface.

[0089] It can be understood that after the microcontroller calls the first API interface, the central processing unit will return the target data to be displayed to the microcontroller. If the secondary display screen is set on the A side of the dual-screen laptop computer, the microcontroller will transmit the target data to be displayed to the secondary display screen through the first adapter device, the screen line, and the second adapter device for display; if the secondary display screen is set on the C side of the dual-screen laptop computer, the microcontroller will directly transmit the target data to be displayed to the secondary display screen for display.

[0090] The embodiment of the present disclosure obtains the target data to be displayed through the first API interface by calling the first API interface corresponding to the target data to be displayed from the central processing unit, and outputs the target data to be displayed to the secondary display screen for display, thereby realizing customization of the display content of the secondary display screen, making the display content of the secondary display screen not restricted by the display content of the main display screen, and improving the scalability of the display content of the secondary display screen.

[0091] FIG14 shows a flow chart of a method for controlling a dual-screen laptop computer according to another embodiment. As shown in FIG14 , the method for controlling a dual-screen laptop computer may include the following steps:

[0092] Step 1401: Acquire a function switching signal;

[0093] Step 1402: If the function switching signal is the first signal, control the secondary display screen to implement the function of a touch panel or a keyboard;

[0094] Step 1403: If the function switching signal is the second signal, the first application programming interface corresponding to the target data to be displayed is called from the central processor to obtain the target data to be displayed through the first application programming interface, and output the target data to be displayed to the secondary display screen for display.

[0095] It is understandable that if the secondary display screen is located on the C side of the dual-screen laptop and is a touch screen, the secondary display screen needs to realize the touchpad function and display function, or needs to display the keyboard function and display function. In order to realize function switching, it is necessary to obtain a function switching signal.

[0096] The user can trigger the embedded controller to output a function switching signal through a hotkey. The microcontroller unit obtains the function switching signal and switches the display function of the touch screen and the function of the touchpad according to the function switching signal, or switches the display function of the touch screen and the function of the keyboard according to the function switching signal.

[0097] During the implementation process, the level signal of the GPIO interface of the embedded controller can be used as a function switching signal. Taking the first signal as a high-level signal and the second signal as a low-level signal as an example, if the function switching signal is a high-level signal, the microcontroller unit realizes the function of the touchpad or the keyboard; if the function switching signal is a low-level signal, the microcontroller unit realizes the display function.

[0098] In some embodiments, the microcontroller unit can call the second API interface corresponding to the touchpad to obtain the first data to be displayed corresponding to the touchpad through the second API interface, or call the third API interface corresponding to the keyboard to obtain the second data to be displayed corresponding to the keyboard through the third API interface; output the first data to be displayed or the second data to be displayed to the secondary display screen for display; in response to the touch data of the secondary display screen, send the touch data to the central processing unit, so that the central processing unit generates the data to be displayed corresponding to the touch data.

[0099] It can be understood that the second API interface can be a Windows virtual touchpad interface. By calling the second API interface, the touchpad function can be synchronized, and the first data to be displayed (i.e., the touchpad interface) can be obtained, and then the touchpad interface can be output to the secondary display screen for display. The user touches the secondary display screen to generate touch data on the secondary display screen, and the secondary display screen outputs the touch data to the microcontroller unit. The microcontroller unit sends the touch data to the central processing unit, and the central processing unit generates data to be displayed corresponding to the touch data (such as data for manipulating the display screen of the main display screen), and outputs the data to be displayed to the main display screen for display.

[0100] The third API interface may be a windows virtual keyboard interface. By calling the third API interface, the keyboard functions may be synchronized to obtain the second data to be displayed (ie, the keyboard interface), thereby realizing the keyboard functions.

[0101] Figure 15 shows a detailed flow chart of Figure 14. As shown in Figure 15, after the application layer software is switched, the microcontroller unit judges the function switching signal. If the function switching signal is the first signal, it switches to the touchpad function. The mainboard notifies the operating system that the function has been switched, and the operating system pushes the API interface (such as the second API interface). The microcontroller unit (MCU) enters the touchpad construction by calling the API interface, and synchronizes the physical functions of the touchpad, thereby realizing the function of the touchpad.

[0102] If the function switching signal is the second signal, the APP customization synchronization in the operating system of the main display screen is performed, the operating system of the main display screen pushes the API interface (such as the first API interface), and the central processing unit performs interface judgment. If the MCU is connected to the MIPI interface, the API interface is pushed through the MIPI interface, the MCU calls the API interface, obtains the customized APP, and outputs it to the secondary display screen for display; if the MCU is connected to the SPI interface or USB interface, the API interface is pushed through the SPI interface or USB interface, the MCU calls the API interface, obtains the customized APP, and outputs it to the secondary display screen for display.

[0103] The embodiment of the present disclosure realizes multiple functions such as a touch panel, user-customized display content, and handwriting input through a secondary display screen with a touch function, and realizes switching of the secondary display screen functions according to user needs.
