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

[0046] The control method provided in the embodiment of the present application is applied to an electronic device, which has at least a first controller, a second controller and a display device, wherein the display device can display display information output by the first controller or the second controller. Correspondingly, the electronic device can switch its state through corresponding instructions, for example, switching to a state with different power consumption. The electronic device in the embodiment of the present application can include a mobile terminal and a fixed terminal, such as a mobile phone, a laptop computer and / or a desktop computer.

[0047] Correspondingly, the operating state of an electronic device can include a working state in which a user can operate the machine for normal operation and a standby working state in which the user cannot operate the machine for operation. Specifically, the system power consumed by the electronic device in the standby working state is lower than that in the working state in which the user can operate the machine for normal operation, for example, including when the electronic device is in a sleep or hibernation state. Because when the electronic device is in the standby working state, the corresponding software or hardware of the electronic device can have different power control or power supply strategies, and different sleep states can be corresponding based on these different strategies. For example, the electronic device can be in the Modern Standby (MS) state, which is a new mode of computer sleep. In this mode, all components except the screen are powered and in a low-power state. In this low-power standby state, if the electronic device needs to resume normal operation, the corresponding components will quickly return to the working state. The electronic device can also be in the S3 sleep state, that is, all components of the electronic device except the memory stop working, to achieve the low-power state of the electronic device. The user of the electronic device can select the corresponding option in the power management menu to enter the corresponding sleep state, or can enter the corresponding control command to put the electronic device into the sleep state. In the sleep state, the various hardware components of the electronic device are in a low-power state.

[0048] An electronic device can be restored from a standby state (e.g., a sleep state or hibernation state) to a normal working state where a user can operate the device to perform normal operations, i.e., wake up from a standby state (e.g., a sleep state or hibernation state). Only after waking up from a standby state (e.g., a sleep state or hibernation state) can a user operate the device to perform normal operations, such as interacting with the electronic device to perform text editing, programming, sending and receiving emails, browsing the web, etc. After waking up from a standby state (e.g., a sleep state or hibernation state), the screen displayed on the electronic device's display is generally the screen that was displayed when the device last entered the standby state (e.g., a sleep state or hibernation state).

[0049] refer to Figure 1 , is a control method provided in Example 1 of the present application, which is applied to an electronic device and may include the following steps:

[0050] S101: When the electronic device is in a second state, control a first controller to store a first image.

[0051] Different states of an electronic device refer to different power consumption states of the electronic device, including the normal working state as described above and the standby working state in which the user cannot operate the device. Furthermore, when the electronic device is in different standby working states, the time it takes to wake up the electronic device to the normal working state is different. In the embodiment of the present application, the first state of the electronic device is a state with low power consumption, such as the electronic device being in the standby working state, which can specifically include the electronic device being in the sleep or hibernation state, and the second state of the electronic device is a state with high power consumption, such as the normal working state.

[0052] Electronic devices can be composed of different controllers, such as a CPU (Central Processing Unit), which interprets electronic device instructions and processes data in computer software. A GPU (Graphics Processing Unit) is a microcontroller on electronic devices that performs image and image-related operations. A TCON (Telecontroller) can also be included, which processes image data input from the electronic device's digital board through a logic board, converting it into signals capable of driving the LCD screen and then sending them directly to the LCD's receiving chip.

[0053] The control method in the embodiments of the present application can be applied to the CPU of an electronic device, where the CPU controls the corresponding controller of the electronic device to execute the relevant control logic. Alternatively, the control method can be applied to the data receiving unit of the electronic device, where the received instructions or data are sent to each controller, and the control unit corresponding to each controller controls the corresponding controller to execute the corresponding instructions or data.

[0054] The second state of the electronic device is a state in which the electronic device is in a relatively high power consumption state. Specifically, a power consumption threshold can be determined. If it is higher than the power consumption threshold, the electronic device is in the second state. The value of the power consumption threshold is the power consumption value corresponding to the normal state of the electronic device. When the electronic device is in the second state, the first controller is controlled to store the first image. The first controller can be a controller that can control the display device to output corresponding content, such as TCON. The first image can be an image corresponding to the output of the display device when the electronic device is in a normal state, or it can be a pre-stored fixed image. Correspondingly, when the electronic device is in the second state, the screen information currently displayed on the display screen can be stored. Furthermore, when a state switching instruction is received, the screen information currently output by the display device can be stored. The corresponding processing method can be to perform snapshot processing on the screen information to obtain the first image, and then store the first image.

[0055] S102: Detect a first instruction, and control the first controller to output a first image to a display device of the electronic device, so that the display device outputs the first image.

[0056] The first instruction is used to instruct the electronic device to switch from a first state to a second state, and the power consumption of the electronic device in the first state is lower than the power consumption of the electronic device in the second state.

[0057] When the first instruction is detected, the electronic device is in a first state, that is, the electronic device is in a state of low power consumption, specifically a state below a power consumption threshold, such as the electronic device is in a sleep state. In this case, the first instruction is a wake-up instruction for the electronic device in the sleep state. When the wake-up instruction is received, the first controller is controlled to output a first image to the display device to end the black screen state corresponding to the electronic device in the sleep state, so that the electronic device can instantly light up the screen after receiving the wake-up instruction, thereby reducing the time the electronic device is in the black screen state after receiving the wake-up instruction.

[0058] S103 : In response to the first controller outputting the first image, controlling the first controller to output the obtained display data to the display device.

[0059] Among them, the display data is the data output by the second controller to the first controller. In the embodiment of the present application, the second controller can be a graphics processing unit GPU. When the first controller outputs the first image, the purpose of the electronic device lighting up from the black screen in the sleep state and outputting the corresponding display interface is achieved. After the display device of the electronic device is awakened, the operating system of the electronic device will be started to put the electronic device into normal working state. When the electronic device is in normal working state, if it receives a user-related processing operation or processing instruction, the second controller will parse the relevant data to obtain the corresponding display data, and then the second controller will output the display data to the first controller. The first controller outputs the display data, which can be a second image corresponding to the display data, or it can be a display data displayed on the corresponding first image. For example, the first image is the desktop interface output by the display device before the electronic device enters the sleep state. When the electronic device wakes up, if it receives a related communication message, the display device will output the communication interface corresponding to the communication message. Thereby, normal operation after waking up the electronic device can be achieved.

[0060] For example, the second controller is a CPU. When the first controller receives a first instruction (such as a wake-up instruction), it can output the first image to the display device. At the same time, it can control the CPU to start the operating system and load the external device driver of the electronic device so that the external device of the electronic device can run. Then, the user of the electronic device can obtain the input instruction based on the external device for the current first image, and then generate display information corresponding to the input instruction, output the display information to the first controller, and then output it to the display device by the first controller. Correspondingly, it can also be directly output to the display device by the CPU.

[0061] A control method provided in a first embodiment of the present application controls a first controller to store a first image when the electronic device is in a second state; detects a first instruction, controls the first controller to output the first image to a display device of the electronic device, so that the display device outputs the first image; and, in response to the first controller outputting the first image, controls the first controller to output obtained display data to the display device, where the display data is data output by the second controller to the first controller. When the electronic device switches from a first state of low power consumption to a second state of high power consumption, the first controller outputs the first image to the display device, so that the electronic device ends the black screen state of the display device earlier during the state switching process, reducing the user's waiting time and improving the user experience.

[0062] On the basis of the above embodiment, after receiving the first instruction and the first controller outputs the first image, the second controller will take over the first controller to output subsequent display data. When the electronic device lights up and wakes up, the second controller completes the subsequent display data output, and the second controller can directly output the corresponding display data to the display device. When the first controller is a TCON, since it is directly connected to the display device, the corresponding display data can be converted into a display screen that matches the output format of the display device. Therefore, the display data output by the second controller can be output to the first controller, and then the first controller outputs the display data to the display device.

[0063] After the first controller outputs the first image, the second controller can be activated to detect whether the second controller has display data output. If so, the first controller receives the display data and outputs the display data to the display device. Correspondingly, the display data output by the second controller can be further detected to determine whether it is the same as the first image. If different, the display data is received and output.

[0064] In one embodiment, the image output by the display device may be determined by the second controller after a predetermined time from when the first controller outputs the first image. Specifically, it is detected whether the time interval for the first controller to output the first image meets a specific time interval condition. If so, the second controller is controlled to output the display data to the first controller, and the first controller is controlled to output the display data to the display device. The time interval condition may be, for example, whether the time interval is greater than a time threshold, specifically, whether the time interval is greater than 0.1S. At this time, the information output by the display device is determined by the second controller, that is, when the user inputs a corresponding control instruction based on the first image, the second controller parses the control instruction, obtains the corresponding display data, outputs the display data to the first controller, and the first controller converts it into a second image that matches the format of the display device, and then outputs the second image to the display device. The second controller may also convert the display data into a corresponding image and output it to the first controller.

[0065] In an embodiment of the present application, when a first instruction instructing an electronic device to switch from a first state to a second state is detected, the first controller outputs the first image to the display device of the electronic device. In order to ensure that the first controller can quickly obtain the first image, the first controller can be controlled to store the first image in a first storage area when the electronic device is in the second state, and the first storage area is a storage area that only receives access instructions from the first controller. The first storage area can be a storage area corresponding to a separate memory, such as the memory can be an SRAM (Static Random-Access Memory). The first image can be stored only by a separate memory, so that the first controller can store and obtain the first image only by interacting with the memory. In this way, the function of the first controller only has the function of data transmission and interaction with the display device, without having to have higher configuration functions. At the same time, this can also avoid the need to start the operating system of the electronic device before accessing the memory to obtain the stored image, so that the image can be obtained for display without starting the operating system, reducing the black screen time of the electronic device.

[0066] In one embodiment of the present application, when the electronic device is in the second state, the first image stored by the first controller includes the image output by the display device of the electronic device when receiving the second instruction, wherein the second instruction instructs the electronic device to switch from the second state to the first state. Correspondingly, the second instruction may be an instruction instructing the electronic device to enter a standby working state (such as entering a sleep state), and the image output by the display device at this time is the image corresponding to the last display frame when the user instructs the electronic device to enter a sleep state. This allows the electronic device to return to the display interface when the user instructs it to enter a sleep state after waking up from the sleep state, ensuring that the user can quickly enter the normal working mode.

[0067] In another embodiment, the first image also includes a pre-stored image, that is, it can be a fixed image pre-stored by the user of the electronic device, so that the pre-stored image can be directly output when the electronic device is awakened, reducing the time when the electronic device is black screen.

[0068] When the electronic device is in the MS sleep state or the S3 sleep state, the display screen is controlled to be powered off, while other components are powered normally. Alternatively, all components except the memory may stop working. Correspondingly, when the electronic device is in the sleep state, some functional components of the electronic device can still operate normally, but the corresponding display information is not output to the display device. In one possible implementation, controlling the first controller to store the first image includes:

[0069] In response to the electronic device being in the first state, detecting whether there is network input information;

[0070] If yes, controlling the second controller to obtain the network input information;

[0071] controlling the second controller to generate a first image corresponding to the network input information;

[0072] The first controller is controlled to store the first image.

[0073] In this embodiment, when the electronic device is in a first state, i.e., a low-power sleep state, the second controller can be in an active state. When the function control corresponding to the network data interaction function of the electronic device is not powered off, the corresponding network input information can be received. However, because the electronic device is in a sleep state, the display image corresponding to the network input information will not be output to the display device. At this time, the second controller will generate an image to be displayed corresponding to the network input information and output it to the first controller, so that the first controller stores the image to be displayed as the first image, so that when the electronic device receives a wake-up command, the first controller will output the first image generated based on the network input information, for example, a display image including an email reception reminder.

[0074] It should be noted that if the second controller is also in a non-working state when the electronic device is in sleep state, the second controller is first controlled to start, and then the second controller receives network input information and generates a corresponding image to be displayed, and then the second controller is controlled to enter a non-working state.

[0075] If network input information is frequent, for example, a user receives a large number of emails every day, if the second controller is constantly activated and then paused, the power consumption of the electronic device will remain high even when it is in a sleep state, which may not meet the user's actual needs. In one embodiment, controlling the second controller to obtain network input information includes: if an input condition corresponding to the input information meets a target condition, controlling the second controller to obtain the network input information.

[0076] The target condition can be set based on the time when the electronic device is in the first state or the frequency of receiving network input information. For example, the time when the electronic device is in the sleep state set by the user is a fixed time zone, which can be specifically 12:30-13:30 noon. Then, within this time period, the network input information can be obtained every 10 minutes, or the network input information can be obtained once at 13:20. Correspondingly, if the network input information is detected to be input frequently, it can be obtained according to the preset acquisition interval, so that only under the target condition, the second controller obtains the network input information and generates the corresponding image to be displayed, so as to avoid increasing the power consumption of the electronic device in the sleep state.

[0077] Since the first image stored by the first controller may be a pre-stored image, if the electronic device corresponds to multiple users, each user may have a corresponding pre-stored image, so that when the electronic device is awakened from a sleep state, the pre-stored image matching the user may be output. Specifically, when the first image includes at least one sub-image, controlling the first controller to output the first image to the display device of the electronic device includes:

[0078] The first controller is controlled to output a target sub-image to a display device of the electronic device, where the target sub-image is associated with a specific user.

[0079] In this embodiment, when it is detected that the first image includes at least one sub-image, a target sub-image matching the current user of the electronic device can be identified from the sub-images. This can be done by obtaining the current electronic device's account information, or by activating the electronic device's biometric control and identifying the current user through biometric features, thereby obtaining and outputting a target sub-image matching the user. This ensures that when a wake-up command is received, the image output by the electronic device's display device matches the current user of the electronic device, improving the user experience.

[0080] See also Figure 2 , which shows a schematic diagram of the structure of a control circuit of an electronic device provided by an embodiment of the present application. In the electronic device, the first controller is a TCON, the second controller is a GPU, the first storage area is a storage area corresponding to the SRAM, the display device is illustrated by taking a display panel (Panel) as an example, and the electronic device also includes an identification chip (such as an artificial intelligence AI identification chip or an embedded controller EC), a south bridge (specifically, a PCH can be used, PCH is Intel's integrated south bridge), the display panel can be an OLED screen, and the electronic device also includes an input control, which is used to receive relevant instructions, such as a biometric recognition component, specifically including a camera-related component for recognizing facial information, pupil information, and fingerprint information, and can also include a Tof sensor for distance recognition, an infrared sensor, and can also include USB format input components such as a keyboard, mouse, and touchpad.

[0081] See also Figure 3 , which is provided in the embodiment of the present application. Figure 2 Flowchart of a method for controlling an electronic device, the method may include the following steps:

[0082] S301 : In response to an electronic device entering a sleep mode, monitor the sleep mode.

[0083] S302: When the electronic device enters the sleep mode, TCON controls SARM to refresh the last frame of the display device or store a preset fixed-screen image.

[0084] S303: When the identification chip or the south bridge monitors that an electronic device is awakened from a sleep state, a notification instruction is sent to the TCON.

[0085] S304 , TCON outputs the last frame of self-refresh data or outputs a preset screen image.

[0086] S305 , when the TCON monitors that the GPU has output display data, the last frame of image output by the display device or the preset screen image is switched to the GPU output.

[0087] In this embodiment, control logic from PCH to identification chip, and from identification chip to TCON is added to the electronic device. When the system enters the sleep state of MS or S3, TCON controls SRAM to refresh the last frame. When the PCH or identification chip monitors that a device needs to wake up from the sleep state, the wake-up instruction can be a trigger instruction for detecting the target user, such as identifying the user through biometric identification methods such as face recognition, fingerprint recognition, etc., or it can be when it is detected that the distance between the user and the electronic device is less than a preset distance, or when it is detected based on input switching instructions such as keyboard and mouse. The identification chip sends a signal instruction to notify TCON in the corresponding data format. After receiving the information to wake up, TCON immediately refreshes the image of the last frame and outputs it to the display panel Panel, or TCON outputs the read fixed display information to the display panel Panel. After TCON receives the display information normally output by the GPU, TCON converts the self-refreshed screen or the output fixed screen to the output of the GPU. Among them, the data transmission formats of each control include but are not limited to I2C bus transmission, GPIO (General-purpose input / output) transmission mode, and INT data mode. The corresponding data transmission format can be selected based on the specific input control and the corresponding controller structure. The embodiment of the present application does not limit this.
