[0002] With the development of Internet technology and computer technology, the interconnection of all things has become possible, especially in the field of display and control, the requirements for device interconnection are getting higher and higher. For example, for safety reasons and the convenience of control, users need to use screen projection to connect their mobile phones with in-vehicle display devices while driving. In order to meet the needs of large-screen viewing, users need to use screen projection to connect their mobile phones with large screens such as TVs. At present, during the process of screen projection connection between mobile phones and other devices, the screen of the mobile phone is always on.

[0003] In the process of conceiving and implementing this application, the inventors found that there are at least the following problems: the screen of the mobile phone is always in a constantly on state during the screen projection process, which consumes a lot of power.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Summary of the invention

[0005] In response to the above technical problems, the present application provides a mobile terminal screen projection method, a mobile terminal and a storage medium, so that the user's mobile terminal does not need to keep the screen on all the time during the screen projection process, thereby saving power of the mobile terminal.

[0006] In order to solve the above technical problems, the present application provides a mobile terminal screen projection method, which is applied to a mobile terminal, and the method comprises the following steps:

[0007] S10: In response to the screen projection operation of the user, sending screen projection information to the terminal device, so that the terminal device displays the screen projection interface of the mobile terminal;

[0008] S20: receiving a control instruction sent by the terminal device, wherein the control instruction is generated by the terminal device in response to a first control operation of the user on the screen projection interface on the terminal device;

[0009] S30: Entering a screen-off state according to the control instruction, and executing a function corresponding to the control instruction in the screen-off state.

[0010] Here, the present application provides a screen projection method. During the screen projection process from a mobile terminal to a terminal device, if the user controls the mobile terminal through the terminal device, the mobile terminal automatically turns off the screen, and the terminal device operations are performed in the screen-off state. The mobile terminal does not need to keep the screen on during the screen projection process, and the screen is turned off when the user does not need the mobile terminal interface, which effectively saves the power consumption of the mobile terminal during the screen projection process and improves the user experience.

[0011] Optionally, after S10, the method further includes:

[0012] S101: Display status selection information;

[0013] S102: if a screen-off state selection operation of the user for the state selection information is received, determining to enter the screen-off state after receiving the control instruction sent by the terminal device, and executing a function corresponding to the control instruction in the screen-off state;

[0014] S103: If a non-screen-off state selection operation for the state selection information is received from the user, determine not to enter the screen-off state after receiving the control instruction sent by the terminal device, and execute the function corresponding to the control instruction in the non-screen-off state.

[0015] Here, the mobile terminal provided by the present application can display a status selection information after being connected to the terminal device for screen projection, for allowing the user to choose whether to turn off the screen when the user controls the mobile terminal through the terminal device during the screen projection process. On the basis of saving the power consumption of the mobile terminal, it meets the different needs of users, improves the flexibility of mobile terminal screen projection, and improves the user experience.

[0016] Optionally, the S30 includes:

[0017] S301: judging whether to enter the screen-off state according to the control instruction and a preset screen-off control instruction list;

[0018] S302: If the preset screen-off control instruction list includes the control instruction, entering a screen-off state, and executing a function corresponding to the control instruction in the screen-off state;

[0019] S303: If the control instruction is not included in the preset screen-off control instruction list, the screen-off state is not entered, and the function corresponding to the control instruction is executed in the non-screen-off state.

[0020] Here, the mobile terminal provided by the present application can, after being connected to the terminal device for screen projection, determine whether to turn off the screen during the execution of the control command according to the control command sent by the terminal device. Through a pre-set list of preset screen-off control commands, the command can be accurately executed in the screen-off or screen-on state according to the control command. On the basis of saving the power consumption of the mobile terminal, it meets the different operation needs of the user, improves the flexibility of the mobile terminal screen projection, and improves the user experience.

[0021] Optionally, the S10 includes:

[0022] In response to the user's screen projection operation, screen projection information is sent to the terminal device so that the terminal device displays the screen projection interface of the mobile terminal and reduces the screen brightness.

[0023] Among them, the present application can reduce the screen brightness when the screen is projected, which not only makes it easier for users to view the display interface of the mobile terminal, but also further saves power consumption.

[0025] S40: In response to the user's screen lock operation on the screen lock button, if the mobile terminal is in the screen off state, the screen off state is maintained.

[0026] Here, the mobile terminal in the present application can control the mobile terminal not to enter the lock screen state after establishing a screen projection connection with the terminal device. If the user presses the lock screen button, the mobile terminal in the screen-off state will still remain in the screen-off state without locking the screen, so as to ensure the continuity and stability of the screen projection operation, prevent the screen projection from being disconnected due to the user accidentally touching the lock screen, further ensure the stability of the screen projection, and improve the user experience.

[0029] Here, the mobile terminal in the present application can control the mobile terminal not to enter the lock screen state after establishing a screen projection connection with the terminal device. If the user presses the lock screen button, the mobile terminal in the bright screen state can enter the screen off state, which not only saves the power consumption of the mobile terminal, but also prevents the screen projection from being disconnected due to the user accidentally touching the lock screen, further ensuring the stability of the screen projection and improving the user experience.

[0030] Optionally, after S30, the method further includes the following steps:

[0101] Based on the above-mentioned mobile terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0102] In the Internet era, the interconnection between mobile terminals and terminal devices has become an important means to facilitate daily life. Among them, screen projection is a common way of interconnection, and users have higher and higher requirements for screen projection. At present, mobile terminals such as mobile phones establish screen projection with personal computers (PCs), car-mounted systems and other systems equipped with screen projection software through Bluetooth, wireless network communication technology (Wi-Fi), QR code scanning, etc., project the content of the mobile phone to the PC, car-mounted and other systems, and operate the mobile phone through the PC, car-mounted and other systems (for example, send text messages through the PC, make calls, etc.). During the screen projection connection process, the user's mobile terminal is always in the screen-on state. In the process of conceiving and realizing this application, the inventor found that there are at least the following problems: the mobile phone is always in the screen-on state during the screen projection process, and the power consumption is large.

[0103] In order to solve the above problems, an embodiment of the present application provides a mobile terminal screen projection method. During the screen projection process of the mobile terminal to the terminal device, if the user controls the mobile terminal through the terminal device, the mobile terminal automatically turns off the screen, and the operations of the terminal device are performed in the screen-off state. The mobile terminal does not need to keep the screen on during the screen projection process, and the screen is turned off when the user does not need the mobile terminal interface, which effectively saves the power consumption of the mobile terminal during the screen projection process and improves the user experience.

[0104] First embodiment

[0105] Figure 3 A flowchart of a mobile terminal screen projection method provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the method includes:

[0106] S10: In response to the user's screen projection operation, the screen projection information is sent to the terminal device so that the terminal device displays the screen projection interface of the mobile terminal.

[0107] Among them, the mobile terminal can send the projection information to the terminal device through a QR code, wired connection, Bluetooth connection or near-field communication, so that the terminal device displays the projection interface of the mobile terminal.

[0108] Optionally, S10 includes:

[0109] In response to the user's screen projection operation, the screen projection information is sent to the terminal device so that the terminal device displays the screen projection interface of the mobile terminal and reduces the screen brightness.

[0110] Optionally, if the brightness of the mobile terminal before the projection information is sent is the first brightness, then during the projection connection process, the projection brightness is reduced to the second brightness, the value of the second brightness should be greater than 0, and the value of the second brightness should be less than the first brightness. It can be understood that the second brightness here can be determined according to actual conditions, and the embodiments of the present application do not impose specific restrictions on this.

[0111] Among them, the embodiment of the present application can reduce the screen brightness when the screen projection is connected, which not only makes it convenient for users to view the display interface of the mobile terminal, but also further saves power consumption.

[0112] S20: Receive a control instruction sent by the terminal device.

[0113] Among them, the control instruction is generated by the terminal device in response to the user's first control operation on the projection interface on the terminal device.

[0115] Among them, the mobile terminal can automatically enter the screen-off mode after the user operates on the terminal device to reduce power consumption.

[0116] Here, an embodiment of the present application provides a screen projection method. During the screen projection process from a mobile terminal to a terminal device, if the user controls the mobile terminal through the terminal device, the mobile terminal automatically turns off the screen, and the operations of the terminal device are performed in the screen-off state. The mobile terminal does not need to keep the screen on during the screen projection process, and the screen is turned off when the user does not need the mobile terminal interface, thereby effectively saving the power consumption of the mobile terminal during the screen projection process and improving the user experience.

[0117] Optionally, after S10, the method further includes the following steps:

[0118] S40: In response to the user's screen lock operation on the screen lock button, if the mobile terminal is in the screen off state, the screen off state is maintained.

[0119] Here, the mobile terminal in the embodiment of the present application can control the mobile terminal not to enter the lock screen state after establishing a screen projection connection with the terminal device. If the user presses the lock screen button, the mobile terminal in the screen-off state will still remain in the screen-off state without locking the screen, so as to ensure the continuity and stability of the screen projection operation, prevent the screen projection from being disconnected due to the user accidentally touching the lock screen, further ensure the stability of the screen projection, and improve the user experience.

[0120] Optionally, after S10, the method further includes the following steps:

[0121] S50: In response to the user's lock screen operation on the lock screen button, if the mobile terminal is in a non-screen off state, it enters the screen off state.

[0122] Here, the mobile terminal in the embodiment of the present application can control the mobile terminal not to enter the lock screen state after establishing a screen projection connection with the terminal device. If the user presses the lock screen button, the mobile terminal in the bright screen state can enter the screen off state, which not only saves the power consumption of the mobile terminal, but also prevents the screen projection from being disconnected due to the user accidentally touching the lock screen, further ensuring the stability of the screen projection and improving the user experience.

[0123] Optionally, after S30, the method further includes the following steps:

[0124] S60: In response to a second control operation of the user on the mobile terminal, entering a screen-on state, and executing a corresponding function according to the second control operation.

[0125] Optionally, after S60, the method further includes the following steps:

[0126] S70: If no third control operation from the user on the mobile terminal is received within the preset sleep time, the screen is turned off.

[0127] Among them, after the screen projection connection is established, the mobile terminal in the embodiment of the present application can light up the screen according to the user's operation on the mobile terminal, which is convenient for the user to operate the mobile terminal. The screen can also be turned off after the user does not operate the mobile terminal within a preset sleep time, further saving power.

[0128] Second embodiment

[0129] This application can also send a query message to the user to determine whether to turn off the screen according to the user's choice. Figure 4 A flowchart of another mobile terminal screen projection method provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the method includes:

[0130] S10: In response to the user's screen projection operation, the screen projection information is sent to the terminal device so that the terminal device displays the screen projection interface of the mobile terminal.

[0132] Optionally, Figure 5 A schematic diagram of a display status selection information interface provided in an embodiment of the present application, where the user can determine their selection operation through touch, click, remote control, voice selection, or input and output devices.

[0133] S102: If a screen-off state selection operation for state selection information is received from the user, it is determined to enter the screen-off state after receiving a control instruction sent by the terminal device, and a function corresponding to the control instruction is executed in the screen-off state.

[0134] S103: If a non-screen-off state selection operation is received from the user for the state selection information, it is determined not to enter the screen-off state after receiving the control instruction sent by the terminal device, and the function corresponding to the control instruction is executed in the non-screen-off state.

[0135] Here, if the user chooses to enter the screen-off state, the mobile terminal executes S20 and S30 operations after the screen projection is connected. If the user chooses not to enter the screen-off state, the screen of the mobile terminal remains on during the screen projection process.

[0136] S20: Receive a control instruction sent by the terminal device.

[0137] Among them, the control instruction is generated by the terminal device in response to the user's first control operation on the projection interface on the terminal device.

[0138] S30: Entering the screen-off state according to the control instruction, and executing the function corresponding to the control instruction in the screen-off state.

[0139] It is understandable that the above Figure 5 The expression of options is only for illustration, and the embodiments of the present application do not impose any specific limitations on the specific interfaces and selections.

[0140] Here, the mobile terminal provided in the embodiment of the present application can display a status selection information after being connected to the terminal device for screen projection, for allowing the user to choose whether to turn off the screen when the user controls the mobile terminal through the terminal device during the screen projection process. On the basis of saving the power consumption of the mobile terminal, it meets the different needs of users, improves the flexibility of mobile terminal screen projection, and improves the user experience.

[0144] S20: Receive a control instruction sent by the terminal device.

[0145] Among them, the control instruction is generated by the terminal device in response to the user's first control operation on the projection interface on the terminal device.

[0146] S301: Determine whether to enter the screen-off state according to the control instruction and the preset screen-off control instruction list.

[0147] Optionally, the preset screen off control instruction list here can be pre-set by the user through a mobile terminal or terminal device.

[0148] S302: If the preset screen-off control instruction list includes a control instruction, entering the screen-off state, and executing the function corresponding to the control instruction in the screen-off state.

[0149] S303: If the preset screen-off control instruction list does not include the control instruction, the screen-off state is not entered, and the function corresponding to the control instruction is executed in the non-screen-off state.

[0150] Here, the mobile terminal provided in the embodiment of the present application can, after being connected to the terminal device for screen projection, determine whether to turn off the screen during the execution of the control command according to the control command sent by the terminal device; through a pre-set list of preset screen-off control commands, the command can be accurately executed in the screen-off or screen-on state according to the control command.
