Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of terminals, and in particular, to a processor frequency adjustment method and an electronic device. BACKGROUND

[0002] Processor frequency is the number of instructions executed by a processor per second, usually expressed in units of hertz (Hz). Processor frequency directly affects the performance of an electronic device. The higher the processor frequency, the faster the execution speed of instructions, and the better the performance of the electronic device. In addition, there is a close relationship between processor frequency and device heat generation. As the processor frequency increases, the device heat generation also increases.

[0003] Currently, when the electronic device is in different running scenarios, its demand for processor frequency and its requirement for device heat generation may be different. Therefore, how to dynamically adjust the processor frequency based on the running scenario so that the processor frequency can meet the demand of the electronic device in the current scenario and at the same time reduce the device heat generation as much as possible is a problem that needs to be solved at present. SUMMARY

[0004] Embodiments of the present application provide a processor frequency adjustment method, so that the electronic device uses the screen state as the basis for adjusting the processor frequency, uses a lower processor frequency when in a folded state, reduces heat generation, and reduces power consumption. When in an unfolded state, a higher processor frequency is used to ensure performance, prevent lag, and improve the overall experience of users.

[0005] In a first aspect, embodiments of the present application provide a processor frequency adjustment method, which is applied to an electronic device including a display screen, and the method includes: obtaining a screen state of the display screen, the screen state including a folded state and an unfolded state; and determining a processor frequency according to the screen state.

[0006] Because the demand for processor performance and the heat dissipation capacity of the electronic device are different in different screen states, by implementing the method, the electronic device can use the screen state as the basis for adjusting the processor frequency, use a lower processor frequency when in a folded state, reduce heat generation, and reduce power consumption. When in an unfolded state, a higher processor frequency is used to ensure performance, prevent lag, and improve the overall experience of users.

[0007] In combination with the first aspect, in some embodiments, the processor frequency corresponding to the folded state is less than the processor frequency corresponding to the unfolded state.

[0008] In combination with the first aspect, in some embodiments, the method further includes: in response to detecting a frequency adjustment event, determining the processor frequency according to the frequency adjustment event and the screen state of the display screen.

[0009] Therefore, the electronic device can flexibly adjust the processor frequency according to the frequency adjustment event and the screen state at the same time. The processor frequency can meet the needs of the electronic device in different running scenarios, avoid lag, and as far as possible reduce the heat and power consumption, and improve the overall experience of the user.

[0010] In combination with the first aspect, in some embodiments, the method further includes: in response to booting or restarting, the electronic device acquires a configuration file, the configuration file being used to indicate the correspondence between the screen state and the processor frequency.

[0011] In combination with the first aspect, in some embodiments, the frequency adjustment event includes at least one of the following: unlocking the device, starting the power saving mode, enabling the device split screen, running the application in the foreground, receiving the user operation, opening the camera, incoming / outgoing call, sending the Beidou message, and starting the applet.

[0012] In combination with the first aspect, in some embodiments, the processor frequency is determined according to the frequency adjustment event and the screen state of the display screen, specifically including: if the frequency adjustment event is a first frequency adjustment event and the screen state of the display screen is a folded state, the processor frequency is a fourth frequency. If the frequency adjustment event is the first frequency adjustment event and the screen state of the display screen is an unfolded state, the processor frequency is a fifth frequency. The fourth frequency and the fifth frequency are different.

[0013] The second aspect, the embodiment of the application provides a processor frequency adjustment method, the method is applied to an electronic device, the electronic device includes a processor module, a frequency adjustment event monitoring module, a display module and a frequency adjustment module, and the method includes: the display module sends a screen state to the frequency adjustment module, the screen state including a folded state and an unfolded state. The frequency adjustment module determines a first frequency according to the screen state. The frequency adjustment module sends a first instruction to the processor module, the first instruction being used to instruct to adjust the processor frequency to the first frequency.

[0014] In combination with the second aspect, in some embodiments, the first frequency corresponding to the folded state is less than the first frequency corresponding to the unfolded state.

[0015] In combination with the second aspect, in some embodiments, the method further includes: in response to restarting, the frequency adjustment module queries the screen state from the display module. The frequency adjustment module determines a second frequency according to the screen state. The frequency adjustment module sends a second instruction to the processor module, the second instruction being used to instruct to adjust the processor frequency to the second frequency.

[0016] In response to detecting the power-on booting and / or in response to detecting the abnormal situation, the frequency adjustment module can be restarted. Since the parameter indicating the screen state in the frequency adjustment module can be initialized when the frequency adjustment module is restarted, the screen state indicated by the parameter is inconsistent with the current screen state. Therefore, by this strategy, the frequency adjustment module can ensure the accuracy of the parameter indicating the screen state stored therein, and further ensure the accuracy of the processor frequency determined subsequently according to the parameter.

[0017] With reference to the second aspect, in some embodiments, the method further includes: the frequency adjustment event monitoring module sending a notification message to the frequency adjustment module, the notification message being used to notify the occurrence of the frequency adjustment event. The frequency adjustment module queries the display module for the screen state. The frequency adjustment module determines the third frequency according to the screen state. The frequency adjustment module sends a third instruction to the processor module, the instruction being used to instruct to adjust the processor frequency to the third frequency.

[0020] In the fifth aspect, an embodiment of the present application provides a computer readable storage medium, which includes instructions, when the instructions are executed on an electronic device, causes the electronic device to execute the method as described in the first aspect or the second aspect.

[0027] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0028] During operation, the electronic device can adjust the processor frequency in response to a detected frequency adjustment event. The frequency adjustment event is an event that can affect the requirement of the electronic device on the processor performance, including an event triggering the electronic device to reduce the requirement on the processor performance, and an event triggering the electronic device to increase the requirement on the processor performance. The frequency adjustment event can include: unlocking the device, starting the power saving mode, enabling the device split screen, running the application in the foreground, receiving the user operation (such as touch operation, double-click operation, sliding operation, etc.), opening the camera, incoming / outgoing call, sending Beidou message, starting the applet, etc. For example, the electronic device starting the application can trigger the electronic device to increase the requirement on the processor performance. The electronic device starting the power saving mode can trigger the electronic device to reduce the requirement on the processor performance. In some implementations, the electronic device can store a corresponding relationship between one or more sets of frequency adjustment events and frequency adjustment frequencies. The frequency adjustment frequency is a processor frequency that can simultaneously meet the performance requirement and the heat requirement of the electronic device when the frequency adjustment event occurs. When no frequency adjustment event is detected, the processor in the electronic device can run at the base frequency. In response to detecting the frequency adjustment event, the electronic device can adjust the processor frequency from the base frequency to the frequency adjustment frequency corresponding to the frequency adjustment event. Thus, the dynamic adjustment of the processor frequency of the electronic device can be achieved.

[0029] A foldable screen device is a device that can be folded to form at least two screens. In some implementations, the foldable screen device can be folded along a folding edge or folding axis to form a first screen and a second screen. In other implementations, the foldable screen device can also be folded along a folding edge or folding axis to form a first screen, a second screen and a third screen. In practical applications, foldable screen devices can be classified into two categories: one category is an electronic device whose foldable screen is folded outward, and the other category is an electronic device whose foldable screen is folded inward. Taking an electronic device that forms a first screen and a second screen after being folded as an example, the electronic device whose foldable screen is folded outward has the first screen and the second screen facing away from each other after being folded. The electronic device whose foldable screen is folded inward has the first screen and the second screen facing each other after being folded. The screen state of the foldable screen device includes a folded state and an unfolded state. In the folded state, the screen remains bent. In this state, the device can be more portable and more suitable for single-handed operation. In the unfolded state, the screen remains unfolded. In this state, the device can provide a larger display and operation area for the user. The display area of the foldable screen device in the folded state is smaller than the display area of the foldable screen device in the unfolded state. Taking an electronic device that forms a first screen and a second screen after being folded as an example, the interface can be displayed on the first screen or the second screen when the electronic device is in the folded state. When the electronic device is in the unfolded state, the interface can be displayed on the first screen and the second screen simultaneously. Since the display area and the upper limit of the number of foreground running applications of the foldable screen device in the unfolded state are larger than those in the folded state, the requirement for the processor performance is also higher. In addition, based on the characteristics of the folding structure, the surface area of the foldable screen device in the unfolded state is larger than that in the folded state, and therefore, the heat dissipation capacity of the foldable screen device in the unfolded state is stronger.

[0030] For the foldable screen device, if the processor frequency is dynamically adjusted according to the frequency adjustment event, the processor frequency may be too high when the foldable screen device is in the folded state, resulting in serious heating and waste of power consumption. When the foldable screen device is in the unfolded state, the processor frequency may be too low, causing device lag and affecting user experience.

The low-frequency baseband signal processed by the baseband processor is transmitted to the application processor. The application processor outputs a sound signal through an audio device (not limited to a speaker 170A, a microphone 170B, etc.), or displays an image or a video through the display 194. In some embodiments, the modem processor can be a separate device. In other embodiments, the modem processor can be independent of the processor 110 and disposed in the same device as the mobile communication module 150 or other functional modules.

[0058] The software system of the electronic device 100 can adopt a layered architecture, an event-driven architecture, a micro-kernel architecture, a micro-service architecture, or a cloud architecture. In the embodiment of the present application, the Android system with a layered architecture is used as an example to illustrate the software structure of the electronic device 100.

[0059] Figure 2 It is a software structure block diagram of the electronic device 100 according to an embodiment of the present application.

[0060] A layered architecture divides software into several layers, each with distinct roles and responsibilities. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers: the application layer, the application framework layer, the system library layer, and the kernel layer.

[0061] The application layer can include a series of application packages.

[0062] like Figure 2 As shown, the application package may include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, etc.

[0063] The application framework layer provides an application programming interface (API) and programming framework for the applications in the application layer. The application framework layer includes some predefined functions.

[0064] like Figure 2 As shown, the application framework layer may include a window manager, a content provider, a phone manager, a resource manager, a frequency modulation event monitoring module, a display module (DisplayEngineService), and the like.

[0065] The window manager is used to manage windows programs. The window manager can acquire the display screen size, determine whether there is a status bar, lock the screen, and capture the screen, etc.

[0066] The content provider is used to store and acquire data, and make the data accessible to the application programs. The data can include videos, images, audios, dialed and received calls, browsing history and bookmarks, phonebook, etc.

[0067] The telephony manager is used to provide the communication function of the electronic device 100. For example, the management of the call state (including call connection, call disconnection, etc.).

[0068] The resource manager provides various resources for the application programs, such as localized strings, icons, pictures, layout files, video files, etc.

[0069] The frequency tuning event monitoring module is used to monitor whether a frequency tuning event occurs. The frequency tuning event is a trigger condition for the electronic device 100 to adjust the processor frequency. In some implementations, in response to detecting that a frequency tuning event occurs, the frequency tuning event monitoring module can send a message to the frequency tuning module in the system library, the message being used to inform the type of the frequency tuning event. In response to detecting the end of the frequency tuning event, the frequency tuning event monitoring module can send a message to the frequency tuning module in the system library, the message being used to inform the elimination of the frequency tuning event.

[0070] The display module is used to monitor the screen state of the electronic device 100. As described above, the screen state of the electronic device 100 includes the folded state and the unfolded state. The description of the folded state and the unfolded state can refer to the related description in the foregoing embodiments, which will not be described here again. In some implementations, the display module can actively send the current screen state of the electronic device 100 to the frequency tuning module in the system library. In other implementations, the display module can respond to the request received from the frequency tuning module and return the current screen state of the electronic device 100 to the frequency tuning module.

[0071] The application program layer and the application program framework layer run in the virtual machine. The virtual machine executes the java files of the application program layer and the application program framework layer into binary files. The virtual machine is used to perform the management of the object life cycle, the management of the stack, the management of the thread, the management of the security and the exception, and the garbage collection, etc.

[0072] The system library can include a plurality of functional modules. For example: the surface manager, the three-dimensional graphics processing library (for example: OpenGL ES), the frequency tuning module, etc.

[0073] The surface manager is used to manage the display subsystem, and provides the fusion of 2D and 3D layers for a plurality of application programs.

[0074] The three-dimensional graphics processing library is used to implement three-dimensional graphics drawing, image rendering, composition, and layer processing, etc.

[0075] The frequency adjustment module is used to support the electronic device 100 to dynamically adjust the processor frequency. Specifically, in some implementations, the frequency adjustment module can determine the processor frequency according to the screen state of the electronic device 100, and instruct the processor to adjust the processor frequency to the processor frequency through the processor driver in the kernel layer. In other implementations, the frequency adjustment module can determine the processor frequency according to the screen state and the frequency adjustment event of the electronic device 100, and instruct the processor to adjust the processor frequency to the processor frequency through the processor driver in the kernel layer. The subsequent embodiments of the present application will be described in detail, which will not be described here.

[0076] The kernel layer is a layer between hardware and software. The kernel layer at least includes display driver, camera driver, audio driver, sensor driver, and processor driver.

[0077] The working flow of the software and hardware of the electronic device 100 will be described below in combination with the capturing and photographing scene.

[0078] When the touch sensor 180K receives the touch operation, the corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into a raw input event (including touch coordinates, timestamp of the touch operation, and other information). The raw input event is stored in the kernel layer. The application framework layer obtains the raw input event from the kernel layer, and identifies the control corresponding to the input event. Taking the touch operation as a touch single-click operation, and the control corresponding to the single-click operation as the control of the camera application icon as an example, the camera application calls the interface of the application framework layer, starts the camera application, and then starts the camera driver through the kernel layer, and captures the still image or video through the camera 193.

[0080] Step S301, obtaining the screen state.

[0081] As described above, the screen state of the electronic device 100 includes the folded state and the unfolded state. The description of the folded state and the unfolded state can refer to the related description in the foregoing embodiments, which will not be described here.

[0082] The electronic device 100 can monitor the screen state. In some implementations, the electronic device 100 can query the screen state at a certain period. The period can be preset, for example, 1 minute. In some implementations, the electronic device 100 can acquire the screen state at a certain period. The period can be preset, for example, 1 minute. It can be understood that the embodiments of the present application do not make specific limitations on the manner in which the electronic device 100 acquires the screen state.

[0083] Step S302, adjusting the processor frequency according to the screen state.

[0084] There can be a corresponding relationship between the screen state and the processor frequency. Specifically, the folded state can correspond to a first frequency, and the unfolded state can correspond to a second frequency. The first frequency is different from the second frequency. In some implementations, the first frequency can be less than the second frequency. The electronic device 100 can determine the corresponding processor frequency according to the screen state, and adjust the processor frequency to the processor frequency corresponding to the screen state.

[0085] In some implementations, in response to booting or restarting, the electronic device 100 can acquire a configuration file, and the configuration file is used to indicate the corresponding relationship between the screen state and the processor frequency. For example, the configuration file can indicate that the folded state corresponds to the first frequency, and the unfolded state corresponds to the second frequency. The first frequency is different from the second frequency. As described above, since the electronic device 100 has different requirements for processor performance and heat dissipation ability in different screen states. Therefore, by using the above strategy, the electronic device 100 can use the screen state as a basis for adjusting the processor frequency, use a lower processor frequency when in the folded state, reduce heat generation, and reduce power consumption. When in the unfolded state, use a higher processor frequency to ensure performance, prevent lag, and improve the overall experience of the user.

[0086] Figure 4 Another flowchart of a processor frequency adjustment method provided by the embodiments of the present application. The method is applied to the electronic device 100. As shown in the figure, the method comprises: Figure 4

[0087] Step S401, in response to detecting a frequency adjustment event, adjusting the processor frequency according to the frequency adjustment event and the screen state.

[0088] The frequency adjustment event is an event that affects the requirement of the electronic device 100 for the processor performance. For the description of the frequency adjustment event, reference can be made to the related description in the foregoing embodiments, which will not be repeated here.

[0089] ​In some implementations, in response to detecting a frequency adjustment event, the electronic device 100 can acquire a screen state. In other implementations, the electronic device 100 can continuously monitor the screen state. As previously described, the screen state of the electronic device 100 includes a folded state and an unfolded state. For descriptions of the folded state and the unfolded state, reference can be made to the relevant descriptions in the foregoing embodiments, which will not be repeated here.

[0090] Different screen states can correspond to different processor frequencies, and different frequency adjustment events can also correspond to different processor frequencies. In the case of the same frequency adjustment event, the processor frequencies corresponding to different screen states can be different. Moreover, the processor frequency corresponding to the folded state can be less than the processor frequency corresponding to the unfolded state. The electronic device 100 can determine the processor frequency corresponding to the frequency adjustment event and the screen state, and adjust the processor frequency to the processor frequency corresponding to the frequency adjustment event and the screen state.

[0091] In some implementations, the electronic device 100 can store different frequency adjustment parameters for different frequency adjustment events. The frequency adjustment parameters include one or more sets of corresponding relationships between screen states and processor frequencies. In response to detecting a frequency adjustment event, the electronic device 100 can first determine the frequency adjustment parameters according to the detected frequency adjustment event. Then, by querying in the determined frequency adjustment parameters, the processor frequency corresponding to the screen state in the frequency adjustment parameters can be determined, and the processor frequency can be adjusted to the processor frequency corresponding to the screen state in the frequency adjustment parameters.

[0092] For the above implementation, in some examples, the frequency adjustment parameter corresponding to one frequency adjustment event can include two sets of corresponding relationship between screen state and processor frequency (corresponding relationship between folded state and processor frequency, and corresponding relationship between unfolded state and processor frequency). Therefore, when the frequency adjustment event is detected, regardless of the screen state, the electronic device 100 can determine the processor frequency corresponding to the screen state by querying in the frequency adjustment parameter corresponding to the frequency adjustment event, and adjust the processor frequency to the processor frequency corresponding to the screen state in the frequency adjustment parameter. Wherein, for the same frequency adjustment event, the processor frequency corresponding to different screen states can be different. In other examples, the frequency adjustment parameter corresponding to one frequency adjustment event can only include one set of corresponding relationship between screen state and processor frequency, for example, only include corresponding relationship between folded state and processor frequency, and not include corresponding relationship between unfolded state and processor frequency. Therefore, when the frequency adjustment event is detected, if in the folded state, the electronic device 100 can determine the processor frequency corresponding to the folded state by querying in the frequency adjustment parameter corresponding to the frequency adjustment event, and adjust the processor frequency to the processor frequency corresponding to the folded state in the frequency adjustment parameter. If in the unfolded state, since the frequency adjustment parameter corresponding to the frequency adjustment event does not include corresponding relationship between unfolded state and processor frequency, the electronic device 100 cannot determine the processor frequency corresponding to the unfolded state by querying in the frequency adjustment parameter corresponding to the frequency adjustment event. At this time, the electronic device 100 can not adjust the processor frequency.

[0093] In some implementations, the electronic device 100 can store different frequency adjustment parameters for different screen states. The frequency adjustment parameter includes one or more sets of corresponding relationship between frequency adjustment event and processor frequency. The electronic device 100 can first determine the frequency adjustment parameter according to the screen state. Then, in response to detecting the frequency adjustment event, the electronic device 100 can determine the processor frequency corresponding to the frequency adjustment event in the determined frequency adjustment parameter by querying in the frequency adjustment parameter, and adjust the processor frequency to the processor frequency corresponding to the frequency adjustment event in the frequency adjustment parameter.

[0094] For the above implementation manners, the correspondence between the frequency adjustment events included in the different frequency adjustment parameters and the processor frequencies can be the same or different. For example, the frequency adjustment parameters corresponding to the folded state can include the correspondence between 2 groups of frequency adjustment events and the processor frequencies. The frequency adjustment parameters corresponding to the unfolded state can include the correspondence between 5 groups of frequency adjustment events and the processor frequencies. For the same frequency adjustment event, the frequency adjustment parameters corresponding to the folded state can include the correspondence between the frequency adjustment event and the processor frequency, and the frequency adjustment parameters corresponding to the unfolded state can not include the correspondence between the frequency adjustment event and the processor frequency. In this case, when the frequency adjustment event is detected, if the electronic device 100 is in the folded state, the electronic device 100 can determine the processor frequency corresponding to the frequency adjustment event by querying the frequency adjustment parameters corresponding to the folded state, and adjust the processor frequency to the processor frequency corresponding to the frequency adjustment event in the frequency adjustment parameters. If the electronic device 100 is in the unfolded state, since the frequency adjustment parameters corresponding to the unfolded state do not include the processor frequency corresponding to the frequency adjustment event, the electronic device 100 can not adjust the processor frequency.

[0095] Based on the above strategy, the electronic device 100 can flexibly adjust the processor frequency according to the frequency adjustment event and the screen state. The processor frequency can meet the needs of the electronic device 100 in different running scenarios, avoid lag, and as much as possible reduce the heat and power consumption, and improve the overall experience of the user.

[0096] Figure 5 Another structural schematic diagram of an electronic device 100 is provided for the embodiments of the present application. As shown in the figure, the electronic device 100 includes a processor module, a frequency adjustment event monitoring module, a display module, and a frequency adjustment module. Among them, Figure 5

[0097] The processor module is used to execute instructions and process data. The processor module includes a processor driver.

[0098] The frequency adjustment event monitoring module is used to monitor whether a frequency adjustment event occurs. For the description of the frequency adjustment event, reference can be made to the related description in the foregoing embodiments, which will not be described here again.

[0099] The display module is used to display images, videos, etc. The display module can also include various display states, such as a folded state, an unfolded state, etc. For the description of the folded state and the unfolded state, reference can be made to the related description in the foregoing embodiments, which will not be described here again.

[0100] The frequency adjustment module is used to support the electronic device 100 to dynamically adjust the processor frequency. The subsequent embodiments of the present application will introduce the process in detail, which will not be described here in detail.

[0101] Figure 6 ​A flowchart of another processor frequency adjustment method provided by the embodiments of the present application. The method is applied to the electronic device 100 shown above. As shown in the figure, the method comprises three implementation manners. Among them: Figure 5 Figure 6 The method comprises three implementation manners. Among them:

[0102] Implementation manner 1

[0103] 1. The display module sends the screen state to the frequency adjustment module.

[0104] The screen state can comprise a folded state and an unfolded state. For the description of the folded state and the unfolded state, reference can be made to the related description in the foregoing embodiments, which will not be repeated here.

[0105] In some implementation manners, the display module can send the screen state to the frequency adjustment module at a certain period. The period can be preset, for example, 1 minute. In some implementation manners, the frequency adjustment module can query the screen state from the display module at a certain period. The period can be preset, for example, 1 minute. In another implementation manner, in response to the change of the screen state, the display module can send the screen state to the frequency adjustment module.

[0106] 2. The frequency adjustment module determines the first frequency according to the screen state.

[0107] For the process that the frequency adjustment module determines the first frequency according to the screen state, reference can be made to the related description in step S302 in the foregoing embodiments, which will not be repeated here.

[0108] 3. The frequency adjustment module sends an instruction to the processor module, and the instruction is used to instruct the processor module to adjust the processor frequency to the first frequency.

[0109] In this way, the screen state can be used as the basis for adjusting the processor frequency. A lower processor frequency is used when in the folded state, so as to reduce the heat and the power consumption. A higher processor frequency is used when in the unfolded state, so as to guarantee the performance, prevent the lag, and improve the overall experience of the user.

[0110] Implementation manner 2

[0111] 1. The frequency adjustment module is restarted.

[0112] In some implementation manners, in response to detecting the power-on, the frequency adjustment module can be restarted. In some implementation manners, in response to detecting the abnormal situation, the frequency adjustment module can also be restarted.

[0113] 2. The frequency adjustment module queries the screen state from the display module.

[0114] 3. The display module sends the screen state to the frequency adjustment module.

[0115] ​In some implementations, the frequency adjustment module can store a parameter indicating the screen state. The frequency adjustment module can determine the processor frequency according to the screen state indicated by the parameter.

[0116] Since the parameter indicating the screen state in the frequency adjustment module can be initialized when the frequency adjustment module is restarted, the screen state indicated by the parameter can be inconsistent with the current screen state. Therefore, through this step, the frequency adjustment module can ensure the accuracy of the parameter indicating the screen state stored therein, and further ensure the accuracy of the processor frequency determined subsequently according to the parameter.

[0117] 4. The frequency adjustment module determines a second frequency according to the screen state.

[0118] For the process of determining the second frequency by the frequency adjustment module according to the screen state, reference can be made to the related description in step S302 in the foregoing embodiments, which will not be repeated here.

[0119] 5. The frequency adjustment module sends an instruction to the processor module, the instruction being used to instruct the processor module to adjust the processor frequency to the second frequency.

[0120] In this way, the screen state can be used as a basis for adjusting the processor frequency, a lower processor frequency is used when in the folded state to reduce heat generation and power consumption, and a higher processor frequency is used when in the unfolded state to ensure performance, prevent lag, and improve the overall experience of the user.

[0121] Embodiment 3:

[0122] 1. The frequency adjustment event monitoring module sends a notification message to the frequency adjustment module, the notification message being used to notify the occurrence of the frequency adjustment event.

[0123] The frequency adjustment event is an event that can affect the requirement of the processor performance of the electronic device 100. For the description of the frequency adjustment event, reference can be made to the related description in the foregoing embodiments, which will not be repeated here.

[0124] 2. The frequency adjustment module determines a third frequency according to the frequency adjustment event and the screen state.

[0125] In some implementations, after receiving the notification message sent by the frequency adjustment module, the frequency adjustment module can obtain the screen state from the display module through querying.

[0126] In some implementations, the frequency adjustment module can also query the screen state from the display module at a certain period, or the display module can actively notify the screen state to the frequency adjustment module at a certain period. The period can be preset, for example, 1 minute. After receiving the notification message sent by the frequency adjustment event monitoring module, the frequency adjustment module can determine the third frequency according to the frequency adjustment event and the screen state obtained most recently.

[0127] In some implementations, the frequency adjustment module can store a parameter indicating the screen state. Upon power-on, the display module can actively send a notification message to the frequency adjustment module to notify the current screen state. The frequency adjustment module can set the parameter initially according to the notification message. Thereafter, in response to detecting a change in the screen state, the display module can send a notification message to the frequency adjustment module to notify the frequency adjustment module to update the parameter. In response to receiving the notification message sent by the frequency event monitoring module to notify the screen state, the frequency adjustment module can update the parameter according to the notification message.

[0128] After receiving the notification message sent by the frequency event monitoring module, the frequency adjustment module can determine the third frequency according to the frequency adjustment event and the screen state indicated by the parameter stored therein.

[0129] For the process of determining the third frequency by the frequency adjustment module according to the frequency adjustment event and the screen state, reference can be made to the relevant description in step S302 in the foregoing embodiments, which will not be described here again.

[0130] 3. The frequency adjustment module sends an instruction to the processor module, the instruction being used to instruct the processor module to adjust the processor frequency to the third frequency.

[0131] In this way, the processor frequency can be flexibly adjusted according to the frequency adjustment event and the screen state at the same time. The processor frequency can meet the needs of the electronic device 100 in different running scenarios, avoid lag, and at the same time, reduce the heat and power consumption as much as possible, and improve the overall experience of the user.
