The user can use the input device of the first electronic device to control the second electronic device.

[0012] Among them, the input device may include a keyboard, a mouse, etc.

[0013] In some examples, the mouse style of the second mouse cursor is different from the mouse style of the first mouse cursor. In other words, the mouse style of the cursor displayed by the input device of the first electronic device on the first electronic device is different from the mouse style of the cursor displayed on the second electronic device when it is shuttled.

Each antenna in the electronic device can be used to cover a single or multiple communication frequency bands. Different antennas can also be reused to improve the utilization of the antennas. For example, antenna 1 can be reused as a diversity antenna for a wireless local area network. In some other embodiments, the antenna can be used in combination with a tuning switch.

[0094] The mobile communication module 150 can provide solutions for wireless communications including 2G / 3G / 4G / 5G, etc., applied to electronic devices. The mobile communication module 150 may include at least one filter, a switch, a power amplifier, a low noise amplifier (LNA), etc. The mobile communication module 150 can receive electromagnetic waves from the antenna 1, and filter, amplify, and process the received electromagnetic waves, and transmit them to the modulation and demodulation processor for demodulation. The mobile communication module 150 can also amplify the signal modulated by the modulation and demodulation processor, and convert it into electromagnetic waves for radiation through the antenna 1. In some embodiments, at least some of the functional modules of the mobile communication module 150 can be set in the processor 110. In some embodiments, at least some of the functional modules of the mobile communication module 150 can be set in the same device as at least some of the modules of the processor 110.

[0095] The modem processor may include a modulator and a demodulator. Among them, the modulator is used to modulate the low-frequency baseband signal to be sent into a medium-high frequency signal. The demodulator is used to demodulate the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After the low-frequency baseband signal is processed by the baseband processor, it is passed to the application processor. The application processor outputs a sound signal through an audio device (not limited to a speaker 170A, a receiver 170B, etc.), or displays an image or video through a display screen 190. In some embodiments, the modem processor may be an independent device. In other embodiments, the modem processor may be independent of the processor 110 and be set in the same device as the mobile communication module 150 or other functional modules.

[0096] The wireless communication module 160 can provide wireless communication solutions including wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared (IR), etc., which are applied to electronic devices. The wireless communication module 160 can be one or more devices integrating at least one communication processing module. The wireless communication module 160 receives electromagnetic waves via the antenna 2, modulates the frequency of the electromagnetic wave signal and performs filtering, and sends the processed signal to the processor 110. The wireless communication module 160 can also receive the signal to be sent from the processor 110, modulate the frequency of it, amplify it, and convert it into electromagnetic waves for radiation through the antenna 2.

[0097] In some embodiments, the antenna 1 of the electronic device is coupled to the mobile communication module 150, and the antenna 2 is coupled to the wireless communication module 160, so that the electronic device can communicate with the network and other devices through wireless communication technology. The wireless communication technology may include global system for mobile communications (GSM), general packet radio service (GPRS), code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division code division multiple access (TD-SCDMA), long term evolution (LTE), BT, GNSS, WLAN, NFC, FM, and / or IR technology. The GNSS may include global positioning system (GPS), global navigation satellite system (GLONASS), Beidou navigation satellite system (BDS), quasi-zenith satellite system (QZSS) and / or satellite based augmentation system (SBAS).

[0098] The electronic device implements the display function through a GPU, a display screen 190, and an application processor. The GPU is a microprocessor for image processing, which connects the display screen 190 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. The processor 110 may include one or more GPUs that execute program instructions to generate or change display information.

[0099] The display screen 190 is used to display images, videos, etc. The display screen 190 includes a display panel.

In the embodiment of the present application, the display screen 190 is also referred to as a screen.

[0100] Digital signal processors are used to process digital signals. In addition to processing digital image signals, they can also process other digital signals. For example, when an electronic device selects a frequency point, a digital signal processor is used to perform Fourier transform on the frequency point energy.

[0101] Video codecs are used to compress or decompress digital videos. Electronic devices can support one or more video codecs. In this way, electronic devices can play or record videos in multiple coding formats, such as Moving Picture Experts Group (MPEG) 1, MPEG2, MPEG3, MPEG4, etc.

[0102] NPU is a neural network (NN) computing processor. By drawing on the structure of biological neural networks, such as the transmission mode between neurons in the human brain, it can quickly process input information and continuously self-learn. NPU can realize applications such as intelligent cognition of electronic devices, such as image recognition, face recognition, voice recognition, text understanding, etc.

[0103] The external memory interface 120 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the electronic device. The external memory card communicates with the processor 110 through the external memory interface 120 to implement a data storage function. For example, files such as music and videos can be stored in the external memory card.

[0104] The internal memory 121 can be used to store computer executable program codes, which include instructions. The processor 110 executes various functional applications and data processing of the electronic device by running the instructions stored in the internal memory 121. The internal memory 121 may include a program storage area and a data storage area. Among them, the program storage area may store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc. The data storage area may store data created during the use of the electronic device (such as audio data, a phone book, etc.), etc. In addition, the internal memory 121 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, a universal flash storage (UFS), etc.

[0105] The electronic device can implement audio functions such as music playing and recording through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the headphone jack 170D, and the application processor.

[0106] The audio module 170 is used to convert digital audio information into analog audio signal output, and is also used to convert analog audio input into digital audio signals. The audio module 170 can also be used to encode and decode audio signals. In some embodiments, the audio module 170 can be arranged in the processor 110, or some functional modules of the audio module 170 can be arranged in the processor 110.

[0107] The speaker 170A, also called a "speaker", is used to convert an audio electrical signal into a sound signal. The electronic device can listen to music or listen to a hands-free call through the speaker 170A.

[0108] The receiver 170B, also called a "earpiece", is used to convert audio electrical signals into sound signals. When the electronic device receives a call or voice message, the voice can be received by placing the receiver 170B close to the human ear.

[0109] Microphone 170C, also called "microphone" or "microphone", is used to convert sound signals into electrical signals. When making a call or sending a voice message, the user can speak by putting their mouth close to the microphone 170C to input the sound signal into the microphone 170C. The electronic device can be provided with at least one microphone 170C. In other embodiments, the electronic device can be provided with two microphones 170C, which can not only collect sound signals but also realize noise reduction function. In other embodiments, the electronic device can also be provided with three, four or more microphones 170C to realize the collection of sound signals, noise reduction, identification of sound sources, and directional recording function, etc.

[0110] The earphone interface 170D is used to connect a wired earphone and can be a USB interface 130 or a 3.5 mm open mobile terminal platform (OMTP) standard interface or a cellular telecommunications industry association of the USA (CTIA) standard interface.

[0111] The input device 180 may include a keyboard, a mouse, etc. The keyboard is used to input English letters, numbers, punctuation marks, etc. into the electronic device, thereby issuing commands to the electronic device, inputting data, etc. The mouse is an indicator for the vertical and horizontal coordinates of the electronic device display system, and is used to input instructions, etc. to the electronic device. Among them, the input device 180 can be connected to the electronic device through a wired connection, for example, the input device 180 is connected to the electronic device through a GPIO interface, a USB interface, etc. The input device 180 can also be connected to the electronic device wirelessly, for example, the input device 180 is connected to the electronic device through Bluetooth, infrared, etc.

[0112] The following uses a laptop computer as the electronic device 100 and a tablet computer as the electronic device 200 as an example to describe in detail the method for lighting up the screen provided in the embodiment of the present application.

[0113] Please refer to Figure 1 , the laptop and tablet are connected by wireless means (e.g., Bluetooth, P2P, LAN, Wi-Fi, wireless ad hoc network). The laptop and tablet can communicate wirelessly. The user can use the laptop's keyboard and mouse to input commands or data to the laptop.

[0114] In some scenarios, please refer to Figure 3A , the user controls the first application running on the laptop computer through the keyboard and mouse. The operating system of the laptop computer receives the keyboard input or the mouse input and generates a keyboard and mouse input event (including the keyboard input event and the mouse input event). The first application running on the laptop computer monitors the keyboard and mouse input event and executes the corresponding processing logic of the keyboard input event or the mouse input event. For example, Figure 3A As shown, the chat application currently running on the laptop processes keyboard input and mouse input. The keyboard cursor flashes in the input box of the chat application. The mouse cursor (first cursor style) of the laptop is displayed on the first application interface of the laptop.

[0115] In some scenarios, please refer to Figure 3B, the user controls the second application running on the tablet computer through the keyboard and mouse. After the laptop computer's operating system receives the keyboard input or mouse input, it generates keyboard and mouse input events (including keyboard input events and mouse input events). The laptop computer's keyboard and mouse management application monitors the keyboard and mouse input events, intercepts the keyboard and mouse input events, so that other applications running on the laptop computer cannot monitor the keyboard and mouse input events; and forwards the keyboard and mouse input events to the tablet computer. The tablet computer receives the keyboard and mouse input events forwarded by the laptop computer, and the second application running on the tablet computer can monitor the keyboard and mouse input events and execute the corresponding processing logic of the keyboard input events or mouse input events. For example, Figure 3B As shown, the photo application currently running on the tablet computer processes keyboard input and mouse input. The mouse cursor (second cursor style) of the tablet computer is displayed on the second application interface of the tablet computer.

[0116] In some examples, the user can slide the mouse to switch to the first application on the laptop to process the keyboard input and the mouse input, or switch to the second application on the tablet to process the keyboard input and the mouse input. Figure 3C As shown, the first application on the laptop computer listens to keyboard input events or mouse input events, and processes the keyboard input or mouse input. The laptop computer's mouse cursor (first cursor style) is displayed on the laptop computer's first application interface. The user slides the mouse to the right, so that the mouse cursor moves beyond the right edge of the laptop computer screen, and switches to the second application on the tablet computer to process the keyboard input and mouse input. Afterwards, the laptop computer's keyboard and mouse management application intercepts local keyboard input events or mouse input events, and forwards the keyboard input or mouse input to the tablet computer for processing. At this point, the tablet computer's mouse cursor (second cursor style) is displayed on the tablet computer's second application interface. In another example, as Figure 3D As shown, the second application on the tablet computer processes keyboard input and mouse input. The tablet computer's mouse cursor (second cursor style) is displayed on the second application interface of the tablet computer. The user slides the mouse to the left, so that the mouse cursor moves beyond the left edge of the tablet computer screen, and switches to the first application on the laptop computer to process keyboard input and mouse input. After that, the laptop computer's keyboard and mouse management application stops intercepting local keyboard input events and mouse input events, and stops forwarding keyboard and mouse input events to the tablet computer. The first application on the laptop computer listens to keyboard input events or mouse input events, and processes the keyboard input or mouse input. At this time, the laptop computer's mouse cursor (first cursor style) is displayed on the first application interface of the laptop computer.

[0117] In some embodiments, Figure 4As shown, the first application on the laptop processes keyboard input and mouse input. After the set conditions are met, the tablet locks the screen and turns off the screen. For example, the set conditions include that there is no application running in the foreground within a set time. For example, the set conditions include that the tablet receives an operation of the user pressing the power button. For another example, the set conditions include that the tablet receives an operation of the user clicking the lock screen icon.

[0118] After the tablet computer is locked and turned off, the user usually needs to press the power button to light up the screen; the operation is relatively cumbersome. The method for lighting up the screen provided in the embodiment of the present application allows the user to slide the mouse towards the tablet computer, and the tablet computer screen can be automatically lit up, which is convenient to operate and provides a good user experience.

[0119] In some embodiments, please refer to Figure 5 , the tablet screen goes off. The first application on the laptop processes the keyboard input and the mouse input. The laptop operating system receives the keyboard input or the mouse input and generates keyboard and mouse input events (including keyboard input events and mouse input events). The first application running on the laptop monitors the keyboard and mouse input events and executes the corresponding processing logic of the keyboard input events or the mouse input events. The laptop mouse cursor (first cursor style) is displayed on the first application interface of the laptop.

[0120] The user moves the mouse. The operating system of the laptop receives the mouse movement input and adjusts the position of the mouse cursor on the screen according to the mouse movement. For example, if the mouse moves a first distance to the right, the position of the mouse cursor on the screen will correspondingly move a second distance to the right; wherein the second distance is proportional to the value of the first distance. In other words, the direction in which the mouse cursor moves on the screen is consistent with the direction in which the mouse moves; and the distance the mouse cursor moves on the screen is proportional to the distance the mouse moves. It is understandable that the above-mentioned mouse can be a mechanical mouse, a mouse simulated by a touchpad, or other forms of devices that can replace the function of a mouse.

[0121] If the movement of the mouse cursor satisfies the first condition, the tablet computer turns on the screen. Figure 5 As shown, the screen of the tablet computer displays an unlocking interface. The mouse cursor (second cursor style) of the tablet computer is displayed on the unlocking interface.

[0122] In one example, the movement of the mouse cursor satisfies the first condition including: the mouse cursor moves to an edge of the laptop screen and continues to move outside the screen.

[0123] In one implementation, when the tablet screen is on, the position of the tablet mouse cursor is displayed corresponding to the position where the mouse cursor moves out of the laptop screen. Figure 6 .like Figure 6As shown in (a), the mouse cursor of the laptop moves out from the right edge of the laptop screen, and correspondingly, the mouse cursor of the tablet is displayed at the left edge of the tablet screen. Figure 6 As shown in (b), the mouse cursor of the laptop moves out from the left edge of the laptop screen, and correspondingly, the mouse cursor of the tablet is displayed at the right edge of the tablet screen. Figure 6 As shown in (c), the mouse cursor of the laptop moves out from the upper edge of the laptop screen, and correspondingly, the mouse cursor of the tablet is displayed at the upper edge of the tablet screen. Figure 6 As shown in (d), the mouse cursor of the laptop computer moves out from the lower edge of the laptop computer screen, and correspondingly, the mouse cursor of the tablet computer is displayed at the lower edge of the tablet computer screen.

[0124] It is understandable that the correspondence between the position where the mouse cursor of the tablet computer appears and the position where the mouse cursor moves out of the laptop screen may include: Figure 6 For example, the laptop computer's mouse cursor moves out from the right edge of the laptop computer's screen, and the tablet computer's mouse cursor is displayed at the right edge of the tablet computer's screen; the laptop computer's mouse cursor moves out from the left edge of the laptop computer's screen, and the tablet computer's mouse cursor is displayed at the left edge of the tablet computer's screen; the laptop computer's mouse cursor moves out from the upper edge of the laptop computer's screen, and the tablet computer's mouse cursor is displayed at the lower edge of the tablet computer's screen; the laptop computer's mouse cursor moves out from the lower edge of the laptop computer's screen, and the tablet computer's mouse cursor is displayed at the upper edge of the tablet computer's screen.

[0125] In one example, see Figure 7 , the laptop computer's mouse cursor moves out from point a on the right edge of the laptop computer screen, and correspondingly, the tablet computer's mouse cursor is displayed at point b on the left edge of the tablet computer screen. The proportion of the ordinate value of point b to the length of the left edge of the tablet computer screen (30%) is the same as the proportion of the ordinate value of point a to the length of the right edge of the laptop computer screen (30%). In this way, the user is given a coherent visual experience of the mouse sliding track.

[0126] In another implementation, when the tablet screen is turned on, the position of the tablet mouse cursor is displayed as the set position. Figure 8 , the laptop computer mouse cursor moves out from the right edge of the laptop computer screen, or moves out from the left edge of the laptop computer screen, or moves out from the top edge of the laptop computer screen, or moves out from the bottom edge of the laptop computer screen, and the tablet computer mouse cursor is displayed in the center of the tablet computer screen.

[0127] In the following embodiments of the present application, the mouse cursor of the laptop moves out from the right edge of the laptop screen, and correspondingly, the mouse cursor of the tablet is displayed at the left edge of the tablet screen. It can be understood that the method of lighting up the screen provided in the embodiments of the present application is also applicable to other implementations.

[0128] For example, Fig. 9A A schematic diagram of a process of lighting up a screen provided in an embodiment of the present application is shown. The method comprises:

[0129] The laptop computer and the tablet computer establish a communication connection. In some examples, the laptop computer and the tablet computer establish a connection through a wireless method (e.g., Bluetooth, P2P, local area network, Wi-Fi, wireless ad hoc network); the laptop computer and the tablet computer can communicate wirelessly. In other examples, the laptop computer and the tablet computer are connected by wire; the laptop computer and the tablet computer communicate by wire. Further, the keyboard and mouse management application of the laptop computer establishes a socket connection with the keyboard and mouse management application of the tablet computer through the socket service port monitored by the keyboard and mouse management application of the tablet computer. A socket is a logical endpoint in each communication connection when applications on two electronic devices communicate; it is an application programming interface (API) for inter-process communication in a network environment. The socket is a combination of an IP address and a port, providing a mechanism for transmitting data packets to an application layer process. A network application writes the information to be transmitted into the socket of the host computer where it is located, and the socket sends this information to the socket of another host computer through a transmission medium connected to a network interface card (NIC), so that the other party can receive this information. After the keyboard and mouse management application of the laptop computer establishes a socket connection with the keyboard and mouse management application of the tablet computer, the keyboard and mouse management application of the laptop computer can communicate with the keyboard and mouse management application of the tablet computer. The keyboard and mouse management application of the laptop monitors the movement of the mouse cursor and notifies the tablet to create a virtual keyboard and mouse. After receiving the notification to create a virtual keyboard and mouse, the keyboard and mouse management application of the tablet notifies the module of the tablet application framework layer to create a virtual keyboard and mouse. The module of the tablet application framework layer creates a virtual keyboard and mouse.

[0130] The keyboard and mouse management application of the tablet computer also monitors the screen on and off broadcast of the operating system. Exemplarily, the screen on and off broadcast includes first information and second information, the first information is used to indicate that the screen is on, and the second information is used to indicate that the screen is off. When the keyboard and mouse management application of the tablet computer receives the first information, it determines that the tablet computer screen is on; when the keyboard and mouse management application of the tablet computer receives the second information, it determines that the tablet computer screen is off. In this way, the keyboard and mouse management application of the tablet computer can determine whether the current screen is on or off.

[0131] When the tablet computer screen is off, the mouse cursor is on the laptop screen. The first application on the laptop monitors the keyboard and mouse input events and processes the keyboard input or mouse input.

[0132] The keyboard and mouse management application of the laptop monitors the movement of the mouse cursor on the screen, and if it is determined that the mouse cursor moves to the edge of the laptop screen and continues to move outside the screen, a mouse shuttle request is sent to the tablet computer. Optionally, after receiving the mouse shuttle request, the keyboard and mouse management application of the tablet computer sends a mouse shuttle response to the laptop.

[0133] The keyboard and mouse management application of the laptop monitors the keyboard and mouse input events, intercepts the keyboard and mouse input events, and prevents the first application on the laptop from monitoring the keyboard and mouse input events. The keyboard and mouse management application of the laptop monitors the keyboard and mouse input events (such as mouse movement events, mouse button events, keyboard button events), and forwards the keyboard and mouse input events to the tablet computer.

[0134] The keyboard and mouse management application of the tablet receives the keyboard and mouse input event, and notifies the module of the application framework layer to write the keyboard and mouse input event to the virtual keyboard or mouse. For example, the keyboard and mouse management application of the tablet receives the mouse cursor movement event, and notifies the module of the application framework layer to write the mouse cursor movement event to the virtual mouse. For example, the keyboard and mouse management application of the tablet receives the keyboard key event, and notifies the module of the application framework layer to write the keyboard key event to the virtual keyboard.

[0135] The keyboard and mouse management application of the tablet computer receives the keyboard and mouse input event, and if it is determined that the screen of the tablet computer is off, it notifies the operating system of the tablet computer to light up the screen.

[0136] like Fig. 9BAs shown, the software system of the tablet computer can adopt a layered architecture. The layered architecture divides the software into several layers, each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the tablet computer may include an application layer, an application framework layer, a local framework and operating environment layer, and a kernel layer. The application layer may include a series of application packages. For example, a screen management application, a keyboard and mouse management application, etc. The application framework layer provides an application programming interface (API) and a programming framework for the application of the application layer. The application framework layer includes some predefined functions. The application framework layer may include an event distribution management service and a power management service (power manager service, PMS). Of course, the application framework layer may also include a timing management service (alarm manager service, AMS), a window management service (window manager service, WMS), a content provider, a view system, a phone manager, a resource manager, a notification manager, etc., and the embodiment of the present application does not impose any restrictions on this. Among them, the power management service can be used to control the lighting or extinguishing of the tablet computer screen. The event distribution management service is used to distribute events. The local framework and operating environment layer may include multiple functional modules. For example: sensor services, surface manager, media libraries, 3D graphics processing library (for example: OpenGL ES), 2D graphics engine (for example: SGL), etc. The surface manager is used to manage the display subsystem. The kernel layer is the layer between hardware and software. The kernel layer contains at least display driver, camera driver, and sensor driver.

[0137] The keyboard and mouse management application of the tablet computer notifies the operating system to light up the screen, and the operating system generates a screen light-up event. The event distribution management service distributes the screen light-up event to the screen light-up and screen light-down management application. The screen light-up and screen light-down management application notifies the power management service of the application framework layer to light up the screen. The power management service notifies the display driver to light up the screen through the surface manager. The display driver controls the display screen to light up the screen.

[0138] When the tablet computer turns on the screen, the mouse cursor (second cursor style) of the tablet computer is displayed on the screen according to the set rules. For example, when the tablet computer turns on the screen, the position of the tablet computer mouse cursor is displayed to correspond to the position where the mouse cursor moves out of the laptop computer screen. For another example, when the tablet computer turns on the screen, the position of the tablet computer mouse cursor is displayed to be the set position.

[0139] In one implementation, the mouse shuttle request includes first indication information for indicating that the mouse cursor moves out of the edge of the laptop screen (e.g., the left edge, the right edge, the upper edge, or the lower edge). Optionally, the mouse shuttle request also includes second indication information for indicating the position where the mouse cursor moves out of the edge of the laptop screen (e.g., the proportion of the ordinate value of point a in the length of the right edge of the laptop screen). In this way, the tablet computer can determine the position of the tablet computer mouse cursor when the screen is turned on based on the first indication information and the second indication information.

[0140] In some embodiments, after the tablet turns on the screen, an unlocking interface is displayed. Fig.10 As shown, the tablet computer receives the user's unlock operation (for example, the user slides the "slide to unlock" slider with the mouse), and in response to the user's unlock operation, the tablet computer displays the application interface before the lock screen. In one implementation, the position where the mouse cursor appears on the application interface before the lock screen is the position where the mouse cursor disappears on the unlock interface. Please refer to Fig.10 , the user slides the "slide to unlock" slider with the mouse, and the mouse cursor slides to point c. The screen is unlocked, and the application interface before the lock screen is displayed. The position of the mouse cursor displayed on the application interface is also the position of point c.

[0141] In some embodiments, please refer to Fig.11 , the tablet screen goes off. The first application on the laptop processes the keyboard input and the mouse input. The laptop operating system receives the keyboard input or the mouse input and generates keyboard and mouse input events (including keyboard input events and mouse input events). The first application running on the laptop monitors the keyboard and mouse input events and executes the corresponding processing logic of the keyboard input events or the mouse input events. The laptop mouse cursor (first cursor style) is displayed on the first application interface of the laptop.

[0142] The laptop computer's operating system receives the mouse movement input and adjusts the position of the mouse cursor on the screen according to the mouse movement. If the movement of the mouse cursor meets the first condition, the tablet computer turns on the screen, and the screen of the tablet computer displays the application interface before the lock screen (for example, the desktop, photo application interface, etc.). The tablet computer's mouse cursor (second cursor style) is displayed on the application interface before the lock screen. In one example, the movement of the mouse cursor meets the first condition including: the mouse cursor moves to the edge of the laptop computer screen and continues to move outside the screen. Among them, the specific implementation process of the tablet computer lighting up the screen after the mouse cursor movement meets the first condition can be referred to. Fig. 9A , I will not go into details here.

[0143] After the tablet screen is turned on, the application interface before the lock screen is directly displayed, and the user does not need to manually unlock the screen. The operation is more convenient and user-friendly.

[0144] In some embodiments, please refer to Fig.12 , the user uses the laptop's keyboard and mouse to control the application (such as the photo application) running on the tablet. After the laptop's keyboard and mouse management application monitors the keyboard input event or the mouse input event, it intercepts the keyboard and mouse input event so that other applications running on the laptop cannot monitor the keyboard and mouse input event; and forwards the keyboard input event or the mouse input event to the tablet. When the tablet receives the keyboard input event or the mouse input event, the application running on the tablet can monitor the keyboard and mouse input event and execute the corresponding processing logic of the keyboard input event or the mouse input event. The tablet's mouse cursor (second cursor style) is displayed on the current application interface of the tablet.

[0145] After the set conditions are met, the tablet computer locks the screen and turns off the screen. For example, the set conditions include that there is no application running in the foreground within the set time. For example, the set conditions include that the tablet computer receives an operation of the user pressing the power button. For example, the set conditions include that the tablet computer receives an operation of the user clicking the lock screen icon.

[0146] When the tablet computer is in the screen-off state, if the user moves the mouse or presses the keyboard or mouse button, the tablet computer lights up the screen. In one implementation, the operating system of the laptop receives keyboard input or mouse input and generates a keyboard input event or a mouse input event. The keyboard and mouse management application of the laptop monitors the keyboard input event or the mouse input event, intercepts the keyboard input event or the keyboard and mouse input event, so that other applications running on the laptop cannot monitor the keyboard input event or the keyboard and mouse input event; and forwards the keyboard input event or the mouse input event to the tablet computer. The keyboard and mouse management application of the tablet computer receives the keyboard input event or the mouse input event forwarded by the laptop computer, and notifies the module of the application framework layer to write the keyboard and mouse input event (keyboard input event or keyboard and mouse input event) into the virtual keyboard or mouse. The keyboard and mouse management application of the tablet computer receives the keyboard and mouse input event, determines that the screen of the tablet computer is off, and notifies the operating system to light up the screen. The operating system of the tablet computer generates a screen lighting event. The event distribution management service of the application framework layer distributes the screen lighting event to the screen lighting and off management application. The screen lighting and off management application notifies the power management service of the application framework layer to light up the screen. The power management service notifies the display driver to light up the screen through the surface manager. The display driver controls the display screen to light up the screen.

[0147] In one example, if Fig.12 As shown, after the tablet computer turns on the screen, the unlocking interface is displayed.

[0148] In another example, Fig.13 As shown, after the tablet computer turns on the screen, the application interface before the lock screen (such as the photo application) is displayed.

[0149] In this way, in an application scenario where a user uses a laptop computer's keyboard and mouse to control a tablet computer, if the tablet computer is locked and the screen is turned off, the user can quickly and easily wake up the tablet computer screen by moving the mouse or pressing a keyboard or mouse button.

[0150] In some embodiments, the laptop computer and the tablet computer are connected wirelessly. The user uses the laptop computer's keyboard and mouse to input instructions or data into the laptop computer. The laptop computer runs one or more first applications (such as a chat application) and displays the interface of the first application. The laptop computer also runs one or more third applications (such as a video application), and the tablet computer displays the interface of the third application. The tablet computer is called an extended screen of the laptop computer, that is, the screen of the tablet computer displays the application interface running on the laptop computer.

[0151] In the embodiment of the present application, the mode in which the laptop displays the third application running on it on the tablet computer with which the laptop has established a communication connection is called the extended screen mode. The display interface of the third application on the tablet computer is called the extended screen interface.

[0152] In some scenarios, please refer to Fig.14A , the user controls the first application running and displayed on the laptop computer through the keyboard and mouse. The operating system of the laptop computer receives the keyboard input or the mouse input and generates a keyboard and mouse input event (including the keyboard input event and the mouse input event). The first application running and displayed on the laptop computer monitors the keyboard and mouse input event and executes the corresponding processing logic of the keyboard input event or the mouse input event. For example, Fig.14A As shown, the chat application running and displayed on the laptop receives keyboard input and mouse input. The keyboard cursor flashes in the input box of the chat application. The mouse cursor (first cursor style) of the laptop is displayed on the first application interface of the laptop.

[0153] In some scenarios, please refer to Fig. 14B , the user controls the third application running on the laptop computer and displayed on the tablet computer screen through the keyboard and mouse. The laptop computer's operating system receives the keyboard input or mouse input and generates keyboard and mouse input events (including keyboard input events and mouse input events). The third application running on the laptop computer and displayed on the tablet computer monitors the keyboard and mouse input events and executes the corresponding processing logic of the keyboard input events or mouse input events. For example, Fig. 14B As shown, the video application running on the notebook computer and displayed on the tablet computer receives keyboard input and mouse input. The mouse cursor (first cursor style) of the notebook computer is displayed on the third application interface of the tablet computer.

[0154] In some examples, the user can slide the mouse to Fig.14A and Fig. 14B Switch between the scenes shown.

[0155] For example, Fig. 14C As shown, a first application (chat application) is running on the laptop computer, and the interface of the first application is displayed. A third application (video application) is also running on the laptop computer, and the tablet computer displays the interface of the third application. The user uses the keyboard and mouse of the laptop computer to control the first application running and displayed on the laptop computer. The first application on the laptop computer listens for and processes keyboard input and mouse input. The mouse cursor (first cursor style) of the laptop computer is displayed on the interface of the first application of the laptop computer.

[0156] The keyboard and mouse management application of the tablet computer monitors whether the extended screen interface is displayed in the foreground. In one implementation, if the keyboard and mouse management application of the tablet computer determines that the extended screen interface is switched to the foreground display, a third message is sent to the keyboard and mouse management application of the laptop computer to instruct the extended screen interface to switch to the foreground display; if the keyboard and mouse management application of the tablet computer determines that the extended screen interface is switched to the background, a fourth message is sent to the keyboard and mouse management application of the laptop computer to instruct the extended screen interface to switch to the background. In this way, the keyboard and mouse management application of the laptop computer can determine whether the extended screen interface is displayed in the foreground or switched to the background.

[0157] The user slides the mouse to the right, so that the mouse cursor moves beyond the right edge of the laptop screen. The laptop's keyboard and mouse management application monitors the movement of the mouse cursor on the screen, determines that the mouse cursor moves to the edge of the laptop screen, and continues to move outside the screen; if it is determined that the extended screen interface is displayed in the foreground, switch to the third application displayed on the extended screen interface to receive and process keyboard input and mouse input. The laptop's mouse cursor (first cursor style) is displayed on the third application interface of the tablet computer. The user can use the laptop's keyboard and mouse to control the third application running on the laptop and displayed on the tablet computer.

[0158] For example, Fig.14DAs shown, the user uses the laptop computer's keyboard and mouse to control a third application running on the laptop computer and displayed on the tablet computer. The laptop computer's mouse cursor (first cursor style) is displayed on the tablet computer's third application interface. The user slides the mouse to the left, so that the mouse cursor moves beyond the left edge of the tablet computer screen. The laptop computer's keyboard and mouse management application monitors the movement of the mouse cursor on the screen, determines that the mouse cursor moves to the edge of the tablet computer screen, and continues to move outside the screen; if it is determined that the extended screen interface is displayed in the foreground, switch to the first application displayed in the foreground of the laptop computer to receive and process keyboard input and mouse input. The laptop computer's mouse cursor (first cursor style) is displayed on the laptop computer's first application interface. The user can use the laptop computer's keyboard and mouse to control the first application running and displayed on the laptop computer.

[0159] In one example, the user slides the mouse to the left, so that the mouse cursor moves beyond the left edge of the tablet screen. The keyboard and mouse management application of the laptop monitors the movement of the mouse cursor on the screen, determines that the mouse cursor moves to the edge of the tablet screen, and continues to move outside the screen; if it is determined that the extended screen interface is in the background, the keyboard and mouse management application of the laptop stops intercepting local keyboard input events and mouse input events, and switches to the first application on the laptop to process keyboard input and mouse input. Figure 3D The scene shown.

[0160] In some embodiments, Fig.15A As shown, a first application (such as a chat application) is running and displayed on the laptop. A third application (such as a video application) is also running on the laptop, and the tablet computer displays the interface of the third application (extended screen interface); that is, the laptop is in extended screen mode. After the set conditions are met, the tablet computer locks the screen and turns off the screen. For example, the setting conditions include not receiving keyboard input or mouse input for a set period of time. For example, the setting conditions include the tablet computer receiving an operation of the user pressing the power button. For another example, the setting conditions include the tablet computer receiving an operation of the user clicking the lock screen icon.

[0161] After the tablet computer is locked and turned off, the user usually needs to press the power button to light up the screen; the operation is relatively cumbersome. The method for lighting up the screen provided in the embodiment of the present application, when the mouse cursor is on the laptop screen, the user slides the mouse towards the tablet computer, and the tablet computer screen can be automatically lit up, which is convenient to operate and provides a good user experience.

[0162] In some embodiments, please refer to Fig. 15B, the laptop runs and displays the first application (such as a chat application). The tablet computer turns off the screen. The user controls the first application running and displayed on the laptop through the keyboard and mouse. The laptop's operating system receives keyboard input or mouse input and generates keyboard and mouse input events (including keyboard input events and mouse input events). The first application monitors the keyboard and mouse input events and executes the corresponding processing logic of the keyboard input events or mouse input events. The laptop's mouse cursor (first cursor style) is displayed on the laptop's first application interface.

[0163] The user moves the mouse. The operating system of the laptop receives the mouse movement input and adjusts the position of the mouse cursor on the screen according to the mouse movement. If the movement of the mouse cursor meets the first condition, the tablet computer turns on the screen. For example, Fig. 15B As shown, the screen of the tablet computer displays an unlocking interface. The mouse cursor (second cursor style) of the tablet computer is displayed on the unlocking interface.

[0164] In one example, the movement of the mouse cursor satisfies the first condition including: the mouse cursor moves to an edge of the laptop screen and continues to move outside the screen.

[0165] In one implementation, when the tablet screen is on, the position of the tablet mouse cursor is displayed corresponding to the position where the mouse cursor moves out of the laptop screen. Figure 6 and Figure 7 , I will not go into details here.

[0166] In another implementation, when the tablet screen is turned on, the position of the tablet mouse cursor is displayed as the set position. Figure 8 , I will not go into details here.

[0167] In one example, after the tablet turns on the screen, an unlocking interface is displayed. The tablet receives an unlocking operation from the user (for example, the user slides a "slide to unlock" slider using a mouse), and in response to the unlocking operation from the user, the screen of the tablet is unlocked. The application interface before the lock screen is displayed.

[0168] In some scenarios, the application interface before the tablet computer is locked is the interface of a third application (such as the interface of a video application) running on the laptop computer. The third application interface of the tablet computer displays the mouse cursor (first cursor style) of the laptop computer.

[0169] In one implementation, the position where the mouse cursor (first cursor style) of the laptop appears on the third application interface on the tablet screen is the position where the mouse cursor (second cursor style) of the tablet disappears on the lock screen interface. Fig. 15B, the user uses the mouse to slide the "slide to unlock" slider bar, and the mouse cursor (second cursor style) of the tablet computer on the lock screen interface slides to point c and disappears. The screen is unlocked, and the application interface before the lock screen is displayed. The position of the mouse cursor (first cursor style) of the laptop computer displayed on the third application interface is also the position of point c. Exemplarily, in one implementation, the tablet computer screen resolution is x_1*y_1, the third application (such as a video application) interface resolution is x_2*y_2, the origin coordinates of the third application (such as a video application) interface are (x_o2, y_o2), the coordinate position where the tablet computer's mouse cursor (second cursor style) disappears on the lock screen interface is (x_p1, y_p1) in the tablet computer screen resolution coordinate system, and the position where the laptop computer's mouse cursor (first cursor style) appears on the third application interface of the tablet computer is (x_p2, y_p2) in the tablet computer screen resolution coordinate system, where,

[0170] x_p2=(x_2 / x_1)*x_p1+x_o2, y_p2=(y_2 / y_1)*y_p1+y_o2.

[0171] For example, Fig.16 A schematic diagram of a process of lighting up a screen provided in an embodiment of the present application is shown. The method comprises:

[0172] The laptop computer and the tablet computer establish a communication connection. In some examples, the laptop computer and the tablet computer establish a connection through a wireless method (e.g., Bluetooth, P2P, local area network, Wi-Fi, wireless ad hoc network); the laptop computer and the tablet computer can communicate wirelessly. In other examples, the laptop computer and the tablet computer are connected by wire; the laptop computer and the tablet computer communicate by wire. Further, the keyboard and mouse management application of the laptop computer establishes a socket connection with the keyboard and mouse management application of the tablet computer through the socket service port monitored by the keyboard and mouse management application of the tablet computer. A socket is a logical endpoint in each communication connection when applications on two electronic devices communicate; it is an application programming interface (API) for inter-process communication in a network environment. The socket is a combination of an IP address and a port, providing a mechanism for transmitting data packets to an application layer process. A network application writes the information to be transmitted into the socket of the host computer where it is located, and the socket sends this information to the socket of another host computer through a transmission medium connected to a network interface card (NIC), so that the other party can receive this information. After the keyboard and mouse management application of the laptop computer establishes a socket connection with the keyboard and mouse management application of the tablet computer, the keyboard and mouse management application of the laptop computer can communicate with the keyboard and mouse management application of the tablet computer.

[0173] The laptop runs and displays a first application (such as a chat application). The laptop also runs a third application (such as a video application), and the tablet displays the interface of the third application (the extended screen interface); that is, the laptop is in extended screen mode. The first application on the laptop receives and processes keyboard and mouse input events, and the mouse cursor of the laptop is displayed on the first application interface (the first cursor style).

[0174] The keyboard and mouse management application of the laptop monitors the movement of the mouse cursor. The keyboard and mouse management application of the laptop notifies the tablet to create a virtual keyboard and mouse. After receiving the notification to create a virtual keyboard and mouse, the keyboard and mouse management application of the tablet notifies the module of the tablet application framework layer to create a virtual keyboard and mouse. The module of the tablet application framework layer creates a virtual keyboard and mouse. The keyboard and mouse management application of the tablet monitors whether the screen is turned on or off, and whether the extended screen interface is displayed in the foreground.

[0175] After the set conditions are met, the tablet locks the screen and turns off the screen. The keyboard and mouse management application of the tablet monitors that the extended screen interface is switched to the background and the screen is turned off, and then notifies the laptop to switch the extended screen interface to the background. The keyboard and mouse management application of the laptop receives the notification that the extended screen interface is switched to the background.

[0176] The keyboard and mouse management application of the laptop monitors the movement of the mouse cursor on the screen, and if it is determined that the mouse cursor moves to the edge of the laptop screen and continues to move outside the screen; and if it is determined that the extended screen interface has been switched to the background; a mouse shuttle request is sent to the tablet computer. Optionally, after receiving the mouse shuttle request, the keyboard and mouse management application of the tablet computer sends a mouse shuttle response to the laptop.

[0177] The keyboard and mouse management application of the laptop monitors the keyboard and mouse input events (for example, mouse movement events, mouse button events, keyboard button events), intercepts the keyboard and mouse input events, and prevents other applications on the laptop from monitoring the keyboard and mouse input events. The keyboard and mouse management application of the laptop forwards the keyboard and mouse input events to the tablet computer. The keyboard and mouse management application of the tablet computer receives the keyboard and mouse input events, and notifies the module of the application framework layer to write the keyboard and mouse input events to the virtual keyboard or mouse. For example, the keyboard and mouse management application of the tablet computer receives the mouse cursor movement event, and notifies the module of the application framework layer to write the mouse cursor movement event to the virtual mouse. For example, the keyboard and mouse management application of the tablet computer receives the keyboard key event, and notifies the module of the application framework layer to write the keyboard key event to the virtual keyboard.

[0178] The keyboard and mouse management application of the tablet receives the keyboard and mouse input event. If it determines that the tablet screen is off, it notifies the tablet operating system to light up the screen. The tablet operating system generates a screen light-up event. The event distribution management service of the application framework layer distributes the screen light-up event to the screen light-up and screen light-down management application. The screen light-up and screen light-down management application notifies the power management service of the application framework layer to light up the screen. The power management service notifies the display driver to light up the screen through the surface manager. The display driver controls the display screen to light up the screen.

[0179] When the tablet computer turns on the screen, the mouse cursor (second cursor style) of the tablet computer is displayed on the screen according to the set rules. For example, when the tablet computer turns on the screen, the position of the tablet computer mouse cursor is displayed to correspond to the position where the mouse cursor moves out of the laptop computer screen. For another example, when the tablet computer turns on the screen, the position of the tablet computer mouse cursor is displayed to be the set position.

[0180] In one example, after the tablet turns on the screen, an unlocking interface is displayed, and the tablet's mouse cursor (second cursor style) is displayed on the unlocking interface. The tablet receives the user's unlocking operation (for example, the user slides the "slide to unlock" slider with the mouse), and in response to the user's unlocking operation, the screen is unlocked, the tablet's mouse cursor (second cursor style) is hidden, and the application interface before the lock screen is displayed, that is, the extended screen interface is switched to the foreground display. The laptop's mouse cursor (first cursor style) is displayed on the extended screen interface.

[0181] In one implementation, the tablet computer unlocks the screen, and the extended screen interface switches to the foreground display. The keyboard and mouse management application of the tablet computer determines that the extended screen interface switches to the foreground display by monitoring the life cycle of the extended screen interface; and notifies the laptop computer that the tablet computer has unlocked the screen and the extended screen interface switches to the foreground display. The keyboard and mouse management application of the laptop computer receives the notification that the tablet computer has unlocked the screen and the extended screen interface switches to the foreground display. The keyboard and mouse management application of the laptop computer stops intercepting keyboard and mouse input events, and stops forwarding keyboard and mouse input events to the tablet computer, so that the application on the laptop computer can monitor the keyboard and mouse input events. The keyboard and mouse management application of the laptop computer determines that the extended screen interface is displayed in the foreground, and switches to the third application (extended screen application) to receive and process keyboard input and mouse input. The third application is an application running on the laptop computer, and its interface displays the mouse cursor of the laptop computer (first cursor style).

[0182] In one implementation, the keyboard and mouse management application of the tablet computer sends mouse cursor information to the laptop computer, and the mouse cursor information is used to indicate the coordinate position where the mouse cursor (second cursor style) of the tablet computer on the lock screen interface disappears when the screen is unlocked. The keyboard and mouse management application of the laptop computer calculates the position of the mouse cursor (first cursor style) of the laptop computer displayed on the tablet computer's extended screen interface based on the mouse cursor information. In this way, it can be achieved that the position where the mouse cursor of the laptop computer appears on the extended screen interface after unlocking is the position where the mouse cursor of the tablet computer disappears on the lock screen interface.

[0183] In some embodiments, Fig.17 As shown, a first application (such as a chat application) is running and displayed on the laptop. A third application (such as a video application) is also running on the laptop, and the tablet computer displays the interface of the third application (extended screen interface); that is, the laptop is in extended screen mode. The user uses a mouse or keyboard to control the third application, that is, the mouse cursor is on the tablet computer screen. The operating system of the laptop computer receives keyboard input or mouse input, and generates keyboard and mouse input events (including keyboard input events and mouse input events). The third application monitors the keyboard and mouse input events, and executes the corresponding processing logic of the keyboard input events or mouse input events. The mouse cursor of the laptop computer (first cursor style) is displayed on the third application interface of the tablet computer.

[0184] After the set conditions are met, the tablet locks the screen and turns it off. For example, the set conditions include not receiving keyboard input or mouse input for a set period of time. For example, the set conditions include the tablet receiving an operation of the user pressing the power button. For another example, the set conditions include the tablet receiving an operation of the user clicking the lock screen icon. The keyboard and mouse management application of the tablet monitors that the screen turns off and the third application interface (extended screen interface) switches to the background; the laptop is notified that the tablet screen turns off and the extended screen interface switches to the background.

[0185] When the tablet computer is in the off-screen state, the user moves the mouse or presses the keyboard or mouse button, and the tablet computer lights up the screen. In one implementation, the operating system of the laptop receives keyboard input or mouse input and generates a keyboard input event or a mouse input event. The keyboard and mouse management application of the laptop monitors the keyboard input event or the mouse input event, and if it is determined that the extended screen interface is in the background, it sends a mouse shuttle request to the tablet computer. Optionally, after receiving the mouse shuttle request, the keyboard and mouse management application of the tablet computer sends a mouse shuttle response to the laptop computer. The keyboard and mouse management application of the laptop computer monitors the keyboard and mouse input event, intercepts the keyboard and mouse input event, so that other applications running on the laptop computer cannot monitor the keyboard and mouse input event; and forwards the keyboard and mouse input event to the tablet computer. The keyboard and mouse management application of the tablet computer receives the keyboard and mouse input event forwarded by the laptop computer, and notifies the module of the application framework layer to write the keyboard and mouse input event (keyboard input event or keyboard and mouse input event) into the virtual keyboard or mouse. The keyboard and mouse management application of the tablet computer receives the keyboard and mouse input event, determines that the screen of the tablet computer is off, and notifies the operating system to light up the screen. The operating system of the tablet computer generates a light-up screen event. The event distribution management service of the application framework layer distributes the screen lighting event to the screen lighting management application. The screen lighting management application notifies the power management service of the application framework layer to light up the screen. The power management service notifies the display driver to light up the screen through the surface manager. The display driver controls the display screen to light up the screen.

[0186] In one example, if Fig.17 As shown, after the screen of the tablet computer is turned on, an unlocking interface is displayed. The mouse cursor (second cursor style) of the tablet computer is displayed on the unlocking interface.

[0187] The tablet computer receives an unlock operation from the user (for example, the user slides the "slide to unlock" slider with the mouse), and in response to the user's unlock operation, the screen of the tablet computer is unlocked, the mouse cursor of the tablet computer (the second cursor style) is hidden, and the application interface before the lock screen (the extended screen interface) is displayed. The mouse cursor of the laptop computer (the first cursor style) is displayed on the third application interface (the extended screen interface) of the tablet computer. In one implementation, the tablet computer unlocks the screen, and the extended screen interface switches to the foreground display. The keyboard and mouse management application of the tablet computer determines that the extended screen interface switches to the foreground display by monitoring the life cycle of the extended screen interface; and notifies the laptop computer that the tablet computer has unlocked the screen and the extended screen interface switches to the foreground display. The keyboard and mouse management application of the laptop computer receives a notification that the tablet computer has unlocked the screen and the extended screen interface switches to the foreground display. The keyboard and mouse management application of the laptop computer stops intercepting keyboard and mouse input events, and stops forwarding keyboard and mouse input events to the tablet computer, so that the application on the laptop computer can monitor the keyboard and mouse input events. The keyboard and mouse management application of the laptop computer determines that the extended screen interface is displayed in the foreground, and switches to the third application (extended screen application) to receive and process keyboard input and mouse input. The third application is an application running on a notebook computer, and the mouse cursor of the notebook computer (the first cursor style) is displayed on the interface of the third application.

[0188] The method for lighting up the screen provided in the embodiment of the present application is that the laptop computer extends the application running on the laptop computer to the tablet computer for display. After the tablet computer screen is turned off, the user can slide the mouse to light up the tablet computer screen, which is convenient and quick. The tablet computer displays the tablet computer's mouse cursor on the lock screen interface, and the user can use the mouse to unlock the tablet computer screen. After the tablet computer screen is unlocked, the laptop computer's mouse cursor is displayed on the extended screen interface, and the user can use the keyboard or mouse to control the application extended on the tablet computer. The position where the laptop computer's mouse cursor appears on the extended screen interface is the position where the tablet computer's mouse cursor disappears on the lock screen interface; it brings an immersive user experience to the user.

[0189] In some embodiments, please refer to Fig.18A , the laptop runs and displays a first application (such as a chat application). The laptop also runs a third application (such as a video application), and the tablet displays the interface of the third application (extended screen interface); that is, the laptop is in extended screen mode. The user uses a mouse or keyboard to control the first application, that is, the mouse cursor is on the laptop screen.

[0190] The user controls the first application running and displayed on the laptop computer through the keyboard and mouse. The operating system of the laptop computer receives the keyboard input or the mouse input and generates keyboard and mouse input events (including keyboard input events and mouse input events). The first application monitors the keyboard and mouse input events and executes the corresponding processing logic of the keyboard input events or the mouse input events. The mouse cursor (first cursor style) of the laptop computer is displayed on the first application interface of the laptop computer.

[0191] After the set conditions are met, the tablet locks the screen and turns it off. The keyboard and mouse management application of the tablet monitors whether the screen turns on or off, and whether the extended screen interface is displayed in the foreground. The keyboard and mouse management application of the tablet monitors that the extended screen interface switches to the background and the screen turns off, and notifies the laptop that the extended screen interface switches to the background and the tablet has turned off.

[0192] The keyboard and mouse management unit of the laptop monitors the movement of the mouse cursor. The user moves the mouse. The operating system of the laptop receives the mouse movement input and adjusts the position of the mouse cursor on the screen according to the mouse movement. If the movement of the mouse cursor satisfies the first condition, the tablet turns on the screen. In one example, the movement of the mouse cursor satisfies the first condition including: the mouse cursor moves to the edge of the laptop screen and continues to move outside the screen.

[0193] The keyboard and mouse management application of the laptop monitors the movement of the mouse cursor on the screen. If it is determined that the mouse cursor moves to the edge of the laptop screen and continues to move outside the screen; and it is determined that the projection extension screen interface is in the background and the tablet computer has been turned off; a mouse shuttle request is sent to the tablet computer. Optionally, after receiving the mouse shuttle request, the keyboard and mouse management application of the tablet computer sends a mouse shuttle response to the laptop computer. The keyboard and mouse management application of the laptop monitors the keyboard and mouse input events (for example, mouse movement events, mouse button events, keyboard button events), intercepts the keyboard and mouse input events, so that other applications on the laptop computer cannot monitor the keyboard and mouse input events. The keyboard and mouse management application of the laptop computer forwards the keyboard and mouse input events to the tablet computer. The keyboard and mouse management application of the tablet computer receives the keyboard and mouse input events, and if it is determined that the tablet computer screen is off, it notifies the tablet computer operating system to light up the screen. The tablet computer operating system generates a screen lighting event. The event distribution management service of the application framework layer distributes the screen lighting event to the screen lighting management application. The screen lighting management application notifies the power management service of the application framework layer to light up the screen. The power management service notifies the display driver to light up the screen through the surface manager. The display driver controls the display screen to light up the screen.

[0194] In one example, after the tablet turns on the screen, it displays the application interface before the lock screen (extended screen interface). The keyboard and mouse management application of the tablet monitors that the extended screen interface switches to the foreground display, and notifies the laptop computer that the extended screen interface switches to the foreground. The keyboard and mouse management application of the tablet notifies the laptop computer that the tablet computer has unlocked the screen and the extended screen interface switches to the foreground display. The keyboard and mouse management application of the laptop computer receives the notification that the tablet computer has unlocked the screen and the extended screen interface switches to the foreground display, stops intercepting keyboard and mouse input events, and enables other applications on the laptop computer to monitor keyboard and mouse input events. The keyboard and mouse management application of the laptop computer determines that the extended screen interface is displayed in the foreground, and switches to the third application (extended screen application) to receive and process keyboard input and mouse input. The third application is an application running on the laptop computer, and its interface displays the laptop computer's mouse cursor (first cursor style).

[0195] In one implementation, when the tablet screen is on, the position of the laptop mouse cursor displayed on the tablet screen corresponds to the position where the mouse cursor moves out of the laptop screen. Figure 6 and Figure 7 , I will not go into details here.

[0196] In another implementation, when the tablet screen is turned on, the position of the laptop mouse cursor displayed on the tablet screen is the set position. Figure 8 , I will not go into details here.

[0197] In some embodiments, please refer to Fig.18B , a first application (such as a chat application) is run and displayed on the laptop. A third application (such as a video application) is also run on the laptop, and the tablet displays the interface of the third application (extended screen interface); that is, the laptop is in extended screen mode. The user uses a mouse or keyboard to control the third application, that is, the mouse cursor is on the tablet screen. The operating system of the laptop receives keyboard input or mouse input, and generates keyboard and mouse input events (including keyboard input events and mouse input events). The third application monitors the keyboard and mouse input events, and executes the corresponding processing logic of the keyboard input events or mouse input events. The mouse cursor of the laptop (first cursor style) is displayed on the third application interface of the tablet.

[0198] After the set conditions are met, the tablet locks the screen and turns off the screen. The keyboard and mouse management application of the tablet monitors that the screen turns off and the third application interface (extended screen interface) switches to the background; it notifies the laptop that the tablet screen turns off and the extended screen interface switches to the background.

[0199] When the tablet computer is in the off-screen state, the user moves the mouse or presses the keyboard or mouse button, and the tablet computer lights up the screen. In one implementation, the operating system of the laptop receives keyboard input or mouse input and generates a keyboard input event or a mouse input event. The keyboard and mouse management application of the laptop monitors the keyboard input event or the mouse input event, and if it is determined that the extended screen interface is in the background, it sends a mouse shuttle request to the tablet computer. Optionally, after receiving the mouse shuttle request, the keyboard and mouse management application of the tablet computer sends a mouse shuttle response to the laptop computer. The keyboard and mouse management application of the laptop computer monitors the keyboard and mouse input event, intercepts the keyboard and mouse input event, so that other applications running on the laptop computer cannot monitor the keyboard and mouse input event; and forwards the keyboard and mouse input event to the tablet computer. The keyboard and mouse management application of the tablet computer receives the keyboard and mouse input event forwarded by the laptop computer, and notifies the module of the application framework layer to write the keyboard and mouse input event (keyboard input event or keyboard and mouse input event) into the virtual keyboard or mouse. The keyboard and mouse management application of the tablet computer receives the keyboard and mouse input event, determines that the screen of the tablet computer is off, and notifies the operating system to light up the screen. The operating system of the tablet computer generates a light-up screen event. The event distribution management service of the application framework layer distributes the screen lighting event to the screen lighting management application. The screen lighting management application notifies the power management service of the application framework layer to light up the screen. The power management service notifies the display driver to light up the screen through the surface manager. The display driver controls the display screen to light up the screen.

[0200] In one example, after the screen of the tablet computer is turned on, the application interface before the lock screen (extended screen interface) is displayed. The keyboard and mouse management application of the tablet computer monitors that the extended screen interface switches to the foreground display, and notifies the laptop computer that the extended screen interface switches to the foreground. The keyboard and mouse management application of the tablet computer notifies the laptop computer that the tablet computer has unlocked the screen and the extended screen interface switches to the foreground display. The keyboard and mouse management application of the laptop computer receives the notification that the tablet computer has unlocked the screen and the extended screen interface switches to the foreground display, stops intercepting keyboard and mouse input events, and enables other applications on the laptop computer to monitor keyboard and mouse input events. The keyboard and mouse management application of the laptop computer determines that the extended screen interface is displayed in the foreground, and switches to the third application (extended screen application) to receive and process keyboard input and mouse input. The third application is an application running on the laptop computer, and its interface displays the laptop computer's mouse cursor (first cursor style).

[0201] In some embodiments, please refer to Fig.19A, a first application (such as a chat application) is run and displayed on the laptop. A third application (such as a video application) is also run on the laptop, and the tablet displays the interface of the third application (extended screen interface); that is, the laptop is in extended screen mode. The user can use the keyboard and mouse to control the first application displayed on the laptop and the third application displayed on the tablet. For example, when the user uses the keyboard and mouse to control the third application, the mouse cursor of the laptop (first cursor style) is displayed on the extended screen interface.

[0202] The fourth application running on the tablet computer is started and switched to the foreground. The tablet computer displays the display interface of the fourth application (non-extended screen interface). The interface of the third application (extended screen interface) is switched to the background. For example, the tablet computer receives a video call request, the video call application switches to the foreground, and the interface of the video application switches to the background. The keyboard and mouse management application of the tablet computer monitors that the extended screen interface switches to the background, and notifies the laptop computer that the extended screen interface switches to the background. After receiving the notification message, the keyboard and mouse management application of the laptop computer sends a mouse shuttle request to the tablet computer. Optionally, after receiving the mouse shuttle request, the keyboard and mouse management application of the tablet computer sends a mouse shuttle response to the laptop computer. The keyboard and mouse management application of the laptop computer monitors the keyboard and mouse input events, intercepts the keyboard and mouse input events of the operating system, so that other applications on the laptop computer cannot monitor the keyboard and mouse input events. The keyboard and mouse management application of the laptop computer monitors the keyboard and mouse input events (for example, mouse movement events, mouse button events, keyboard button events), and forwards the keyboard and mouse input events to the tablet computer. The fourth application running on the tablet computer monitors the keyboard and mouse input events and executes the corresponding business logic. The mouse cursor (second cursor style) of the tablet computer is displayed on the fourth application interface of the tablet computer. For example, Fig.19A As shown, the mouse cursor (second cursor style) of the tablet computer is displayed on the fourth application interface (video call application interface) running on the tablet computer. It can be understood that the fourth application running on the tablet computer can also be the second application in the above embodiment.

[0203] In one implementation, the position where the mouse cursor of the tablet computer appears on the fourth application interface on the tablet computer screen is the position where the mouse cursor of the laptop computer disappears on the extended screen interface. Exemplarily, the tablet computer screen resolution is x_1*y_1, the interface resolution of the application (such as a video application) extended to the tablet computer is x_2*y_2, the origin coordinates of the application (such as a video application) interface extended to the tablet computer are (x_o2, y_o2), the position where the mouse cursor of the laptop computer disappears on the extended screen interface is (x_q1, y_q1) in the tablet computer screen resolution coordinate system, and the position where the mouse cursor of the tablet computer appears on the fourth application interface running on the tablet computer is (x_q2, y_q2) in the tablet computer screen resolution coordinate system, wherein,

[0204] x_q2=(x_2 / x_1)*x_q1+x_o2, y_q2=(y_2 / y_1)*y_q1+y_o2.

[0205] In some examples, a fourth application running on the tablet computer is closed. Fig.19B As shown, the tablet computer receives the operation of the user clicking the "Reject" button on the interface, and in response to the user clicking the "Reject" button on the interface, closes the video call application. The extended screen interface is switched to the foreground display. The keyboard and mouse management application of the tablet computer monitors that the extended screen interface is switched to the foreground, and notifies the laptop computer that the extended screen interface is switched to the foreground. After receiving the notification message, the keyboard and mouse management application of the laptop computer stops intercepting keyboard and mouse input events, and stops forwarding keyboard and mouse input events to the tablet computer, so that applications on the laptop computer (such as a third application) can monitor keyboard and mouse input events.

[0206] The third application interface (extended screen interface) displayed on the tablet computer displays the mouse cursor (first cursor style) of the laptop computer. Fig.19B As shown, the mouse cursor of the laptop computer (first cursor style) is displayed on the video application interface.

[0207] In one implementation, on the tablet computer screen, the position where the mouse cursor of the laptop computer appears on the extended screen interface is the position where the mouse cursor of the tablet computer disappears on the fourth application interface running on the tablet computer.

[0208] The method for lighting up the screen provided in the embodiment of the present application can switch between the extended screen interface and the non-extended screen interface after the tablet screen is lit. When the tablet display interface switches between the extended screen interface and the local application interface, the mouse cursor style switches accordingly.

[0209] In some embodiments, please refer to Fig.19C, a first application (such as a chat application) is running and displayed on the laptop. A third application (such as a video application) is also running on the laptop, and the tablet computer displays the interface of the third application (extended screen interface); that is, the laptop is in extended screen mode. The user uses the keyboard and mouse to control the first application displayed on the laptop and the third application displayed on the tablet computer. The mouse cursor of the laptop is displayed on the extended screen interface (first cursor style).

[0210] The fourth application running on the tablet computer is started and switched to the foreground. The tablet computer displays the display interface of the fourth application (non-extended screen interface). The interface of the third application (extended screen interface) is switched to the background. For example, the tablet computer receives a video call request, the video call application switches to the foreground, and the interface of the video application switches to the background. The keyboard and mouse management application of the tablet computer monitors that the extended screen interface switches to the background, and notifies the laptop computer that the extended screen interface switches to the background. After receiving the notification message, the keyboard and mouse management application of the laptop computer sends a mouse shuttle request to the tablet computer. Optionally, after receiving the mouse shuttle request, the keyboard and mouse management application of the tablet computer sends a mouse shuttle response to the laptop computer. The keyboard and mouse management application of the laptop computer monitors the keyboard and mouse input events, intercepts the keyboard and mouse input events of the operating system, so that other applications on the laptop computer cannot monitor the keyboard and mouse input events. The keyboard and mouse management application of the laptop computer monitors the keyboard and mouse input events (for example, mouse movement events, mouse button events, keyboard button events), and forwards the keyboard and mouse input events to the tablet computer. The fourth application running on the tablet computer monitors the keyboard and mouse input events and executes the corresponding business logic. The mouse cursor (second cursor style) of the tablet computer is displayed on the fourth application interface of the tablet computer. Exemplarily, the mouse cursor (second cursor style) of the tablet computer is displayed on the video call application interface.

[0211] The keyboard and mouse management application of the tablet monitors mouse movement. If the mouse cursor moves to the edge of the tablet screen and continues to move outside the screen, the keyboard and mouse management application of the tablet sends a mouse shuttle request to the laptop. The keyboard and mouse management application of the laptop stops intercepting keyboard and mouse input events, and stops forwarding keyboard input and mouse input to the tablet, so that the application on the laptop can monitor keyboard and mouse input events.

[0212] The laptop receives keyboard input or mouse input, the first application monitors the keyboard and mouse input events, and processes the keyboard input or mouse input; the third application runs in the background. The mouse cursor of the laptop is displayed on the first application interface, that is, the mouse cursor of the laptop is displayed on the screen of the laptop. For example, Fig.19C As shown, the mouse cursor (first cursor style) of the laptop computer is displayed on the chat application interface of the laptop computer.

[0213] The method for lighting up the screen provided in the embodiment of the present application is that the laptop computer extends the screen of the application running on the laptop computer to the tablet computer display.
