[0044] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0045] The dual-system detachable laptop computer includes two parts: a detachable tablet end and a base end. The tablet end includes an OLED display, and after the tablet end is detached from the base end, it can be used as a tablet computer. The base end includes input devices such as a keyboard and a touchpad. When the tablet end and the base end are connected together, it can be used as a laptop computer. The tablet end and the base end run different operating systems respectively. For example, the tablet end is equipped with an ARM SOC (system-on-chip based on ARM architecture) hardware system and runs the Android operating system. The base end is equipped with an X86 platform hardware architecture and runs the Windows operating system.

[0046] When the tablet and the base are connected together, after pressing the power button, the base's operating system controls the display by default. When the tablet is unplugged from the base, the tablet's operating system controls the display. When the tablet is reinserted into the base, the base's operating system controls the display again. If the plugging and unplugging actions occur when the device is powered, this process is called hot plugging. Due to the characteristics of the OLED display itself, during the hot plugging process, after swapping the operating system control, the OLED display needs to be guided to perform the power-off sequence and power-on sequence before it can display normally, otherwise it will be in a black screen state. At present, this boot process usually requires pressing the power off button or opening and closing the cover of the device to complete.

[0047] The process of transferring the control of the OLED display between the operating system on the base and the operating system on the tablet while the tablet and base are connected and powered on is called hot swapping. Similar to hot swapping, the hot swapping process also requires guiding the OLED display to power off and on after the system control is switched. Guiding the OLED display to power off and on by pressing the power off button or opening and closing the cover of the device will interrupt the operating state of the operating system, thus giving users a bad user experience.

[0048] In view of the above problems, according to the first aspect of the embodiment of the present disclosure, a dual-system device is proposed, such as Figure 1 As shown, the dual-system device includes a first body and a second body that are detachably connected, the first body runs a first system, the second body includes a display and runs a second system, and the display is an OLED display. The first system and the second system are different operating systems, for example, the first system is a Windows system, and the second system is an Android system. The specific forms of the first system and the second system are not limited in the present disclosure.

[0049] According to a second aspect of the embodiment of the present disclosure, a control method for a dual-system device is provided. The method is applied to the dual-system device of the above embodiment, such as Figure 2 As shown, the control method includes:

[0050] Step 101: a first body is connected to a second body, and a first system controls a display to display a first picture.

[0051] In the initial state, the first body is connected to the second body, the operating system of the first body is in S0 state (working state) and controls the display to display the screen of the system, that is, the first screen.

[0052] Step 102: In response to a first trigger signal, the second system controls the display to display a second picture.

[0053] The first trigger signal is used to trigger the transfer of the control right of the display from the first system to the second system. When the first trigger signal occurs, the device responds to the first trigger signal and transfers the control right of the display from the first system to the second system, so that the second system controls the display to display its picture, that is, the second picture.

[0054] Step 103, in response to the second trigger signal, driving the display through a video graphics array (VGA) to complete a power-off sequence and a power-on sequence, so that the first system controls the display to continue to display the first picture.

[0055] The second trigger signal is used to trigger the transfer of the control right of the display from the second system back to the first system. When the second trigger signal occurs, the control right of the display is transferred from the second system to the first system in response to the second trigger signal. For the first subject, the display is equivalent to a pluggable external device, because the first subject currently does not support hot plugging or hot swapping of external devices. Therefore, after the control right of the display is returned to the first system, the embodiment drives the analog device through VGA (Video Graphics Array) to perform the action of opening and closing the cover, and then guides the display to perform the power-off timing and power-on timing, so that the display can continue to display the first picture. The VGA driver is a program inside the laptop computer, which is used to transmit data between the system and the display.

[0056] In this process, the first subject drives the analog device through VGA to open and close the cover, thereby guiding the display to perform power-off and power-on sequences. However, in this process, the first system is not notified to perform the actual opening and closing of the cover, and the first system is always in S0 state during this process. Therefore, without any manual operation, the display can complete hot plugging or hot swapping under the first system, and the displayed content can be seamlessly switched between the first screen and the second screen. After the control system is converted, there is no need to manually operate it to turn it on and off or open and close the cover, which improves the user experience.

[0057] In the control method disclosed in the present invention, the process of opening and closing the cover of the device is simulated through the hardware architecture and the underlying software, thereby realizing hot plugging or hot swapping of the display in the first system, while keeping the operating system in the S0 state unchanged, providing flexibility and convenience for display management in dual-system switching application scenarios.

[0058] In one embodiment of the present disclosure, in response to the first trigger signal, the second system controls the display to display the second picture, including: in response to the first trigger signal, switching the control of the display from the multiplexer of the first system to the second system; the second system controls the display to complete the power-off sequence and the power-on sequence so that the display displays the second picture.

[0059] like Figure 3 As shown, the second body includes an ARM SOC and a display, and the first body includes a MUX (multiplexer), a BIOS, an EC (Embedded Controller) and a CPU (Central Processing Unit) supported by X86. In this embodiment, the first system controls the display through a multiplexer. After responding to the first trigger signal, the control of the display is transferred from the multiplexer to the ARM SOC. After the second system controls the display to complete the power-off timing and the power-on timing, the display successfully displays the second picture. In the control method disclosed in the present invention, since the display is part of the second body, the operation of the second body controlling the display to perform the power-off timing and the power-on timing is relatively simple and common. Therefore, in the present disclosure, no specific limitation is made on the control of the display by the second body.

[0060] In one embodiment of the present disclosure, the response to the second trigger signal and guiding the display to complete the power-off sequence and the power-on sequence through the VGA driver so that the first system controls the display to continue to display the first screen include: responding to the second trigger signal, the second system guiding the display to complete the power-off sequence; sending the display completion power-off sequence event to the BIOS (Basic Input Output System) of the first body; the BIOS of the first body receives the display completion power-off sequence event, and guiding the display to complete the power-off sequence and the power-on sequence through the VGA driver so that the first system controls the display to continue to display the first screen.

[0061] The ARM SOC of the second body responds to the second trigger signal, and the second system guides the display to perform the power-off sequence. After completing the power-off sequence, the ARM sends the display power-off sequence completion event to the EC of the first body. After receiving the event and the second trigger signal, the EC sends an interrupt signal to the BIOS through the SCI (Serial Communication Interface). After receiving the interrupt signal, the BIOS simulates an opening and closing operation, but does not notify the first system to perform a real opening and closing operation.

[0062] The specific operation of guiding the display to complete the power-off sequence and power-on sequence through the VGA driver is as follows: the BIOS sets the lid bit status of the VGA driver to "closed" through programming. However, this operation does not trigger the global sleep or hibernation mechanism of the first system. It only affects the VGA driver's judgment of the display status, making it believe that the lid of the device has been closed, and then guides the display to perform the power-off sequence according to the preset logic. After the display completes the power-off sequence, the BIOS sets the lid bit status of the VGA driver to "open" again to simulate the device's lid opening operation. This operation is performed after a preset time (such as about 1 second) to ensure that the power-off sequence of the display is fully executed. After the VGA driver detects that the lid bit status changes to "open", it guides the display to perform the power-on sequence. This allows the display to successfully display the first screen.

[0063] In one embodiment of the present disclosure, the first trigger signal is a first user trigger signal, and the second trigger signal is a second user trigger signal.

[0064] Among them, the first user trigger signal is a signal triggered by the user through some form of input device (such as keyboard, mouse, button, etc.) or specific user interaction (such as gesture, voice command, etc.). For example, on an electronic device, a user presses a specific button, and this action is recognized by the system as a first user trigger signal. The second user trigger signal is a signal triggered again by the user in the same form. When the first trigger signal is a first user trigger signal and the second trigger signal is a second user trigger signal, the physical connection state between the first subject and the second subject is always in a mutually connected state.

[0065] Taking the first user trigger signal as the user pressing a hot key, the second user trigger signal as pressing the hot key again, the first system as the Windows system, and the second system as the Android system as an example, the control method of the present disclosure is described. Figure 4 As shown, the specific steps include:

[0066] The first subject and the second subject process the connection status. If the user presses the hot key, in response to the first user trigger signal, the EC sends an interrupt signal to the BIOS. After the BIOS responds to the interrupt signal, it puts Windows and VGA in S0 state. At the same time, the control of the display is transferred from the MUX of the first subject to the AEM Android end of the first subject. After the Android end completes the power-off sequence and power-on sequence of the display, it controls the display to display the second screen. If the user presses the hot key again, in response to the second user trigger signal, after the display completes the power-off sequence on the ARM end, the EC sends an interrupt signal to the BIOS. The BIOS responds to the interrupt signal and sets the opening and closing cover state of the VGA drive to closed. After the preset time, the opening and closing cover state is set to open, thereby guiding the display to perform the power-off sequence and power-on sequence. This process does not notify the OS. After completion, the Windows end controls the display to display the first screen.

[0067] In one embodiment of the present disclosure, the first trigger signal is a signal for disconnecting the first subject from the second subject, and the second trigger signal is a signal for establishing a connection between the first subject and the second subject.

[0068] In this embodiment, the first trigger signal may also be generated when the physical connection between the first body and the second body is disconnected, and the second trigger signal may be generated when the physical connection between the first body and the second body is connected again.

[0069] In one embodiment of the present disclosure, if the first trigger signal is a signal for disconnecting the first body from the second body, and the second trigger signal is a signal for establishing a connection between the first body and the second body, the method further includes: in response to the disconnection signal, switching the mode of the multiplexer of the first body to protect the display output; in response to the establishment signal, switching the mode of the multiplexer of the first body to release the display output.

[0070] When the first trigger signal is a signal for disconnecting the first body from the second body, the system needs to ensure that hardware damage will not be caused by continuing to send signals to the removed display. Therefore, when the disconnection signal is detected, the multiplexer switches to the protection display mode, which can isolate the display-related signals to protect the hardware components. On the other hand, in the protection display mode, the system can stop supplying power to the multiplexer or related circuits, thereby reducing the overall energy consumption of the device. When the first body and the second body are reconnected together, the second body responds to the connection establishment signal and switches the mode of the multiplexer to release the display output. In this mode, the multiplexer can ensure that the display signal of the first system can reach the display correctly, so that the first picture is displayed normally.

[0071] Continuing with the example that the first system is a Windows system and the second system is an Android system, the first trigger signal is a signal for disconnecting the first subject from the second subject, and the second trigger signal is a signal for establishing a connection between the first subject and the second subject. Figure 5 As shown, the control method of the present disclosure may specifically include the following steps:

[0072] If the second body is removed from the first body, in response to the disconnection signal, the EC sends an interrupt signal to the BIOS. In response to the interrupt signal, the BIOS sets the mode switch of the multiplexer to protect the display output by pulling up the GPIO. If the second body is inserted into the first body, in response to the connection establishment signal, the EC sends an interrupt signal to the BIOS. In response to the interrupt signal, the BIOS sets the mode switch of the multiplexer to release the display output by pulling down the GPIO. The mode switch of the multiplexer is set to release the display output. After receiving the power-off sequence of the display on the ARM side, the EC sends an interrupt signal to the BIOS. In response to the interrupt signal, the BIOS sets the opening and closing cover state of the VGA drive to closed. After the preset time, the opening and closing cover state is set to open, thereby guiding the display to perform the power-off sequence and the power-on sequence. This process does not notify the OS. After completion, the Windows side controls the display to display the first picture.

[0073] According to an embodiment of the present disclosure, the present disclosure also provides an electronic device and a readable storage medium.
