Therefore, the above description should not be considered as limiting, but only as an example of an embodiment.

[0029] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0030] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present application. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0031] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0032] A display control method in an embodiment of the present application determines a target refresh rate through a state reference signal sent by a signal acquisition unit and a display signal sent by a processor, and when the current image refresh rate of the display is different from the target refresh rate, switches the refresh rate of the display to the target refresh rate, thereby dynamically adjusting the refresh rate of the display, thereby reducing the power consumption of the electronic device and achieving energy saving.

[0033] The display control method is applied to electronic devices such as Figure 1 As shown, the following steps are included:

[0034] Step S101: obtaining a state reference signal sent by a signal acquisition unit of the electronic device.

[0035] In this embodiment, the electronic device may be, for example, a desktop computer, a laptop computer, a tablet computer, etc. The electronic device includes a signal acquisition unit, a processor, and a display. In some embodiments, the electronic device further includes a display control unit. The execution subject of the embodiment of the present application may be the display control unit. In a specific application scenario, the display control unit may be a display control chip.

[0036] The signal acquisition unit can acquire a state reference signal of the electronic device, and the state reference signal can represent the state of the electronic device. The signal acquisition unit can send the state reference signal in real time or at a specified time interval, and obtain the state reference signal from the signal acquisition unit.

[0037] Step S102: obtaining a display signal sent by a processor of the electronic device.

[0038] In this embodiment, the display signal can be an image signal or a control command signal. The image signal may include any one of the signals such as image frame, image refresh rate information, etc. The control command signal may include any one of the signals such as refresh rate change request signal, power status signal, etc.

[0039] The display signal sent by the processor is obtained, and the target refresh rate can be determined based on the state reference signal and the display signal.

[0040] It is understandable that there is no particular order in which step S101 and step S102 are executed.

[0041] Step S103: determining a target refresh rate corresponding to the state reference signal and the display signal based on a target control strategy.

[0042] In this embodiment, the target refresh rate is the refresh rate that the display is to execute, and the target refresh rate may be lower than the current image refresh rate of the display, may be higher than the current image refresh rate of the display, or may be the same as the current image refresh rate of the display. Based on the target control strategy, the target refresh rate corresponding to the state reference signal and the display signal is determined, and then it can be determined whether to switch the refresh rate according to the target refresh rate.

[0043] Step S104: when the current image refresh rate of the display of the electronic device is different from the target refresh rate, switch the refresh rate of the display to the target refresh rate.

[0044] In this embodiment, the current image refresh rate of the display is compared with the target refresh rate. If the current image refresh rate of the display is different from the target refresh rate, it means that the current image refresh rate of the display does not match the current state of the electronic device, and the refresh rate of the display is switched to the target refresh rate.

[0045] For example, if the target refresh rate is lower than the current image refresh rate, the refresh rate of the display is reduced to the target refresh rate, thereby reducing the power consumption of the electronic device. If the target refresh rate is higher than the current image refresh rate, the refresh rate of the display is increased to the target refresh rate, thereby improving the display effect of the display and improving the user experience.

[0046] It can be understood that if the current image refresh rate of the display is the same as the target refresh rate, the refresh rate of the display is kept unchanged.

[0047] The display control method of the embodiment of the present application is applied to an electronic device, and includes: obtaining a state reference signal sent by a signal acquisition unit of the electronic device; obtaining a display signal sent by a processor of the electronic device; determining a target refresh rate corresponding to the state reference signal and the display signal based on a target control strategy; and switching the refresh rate of the display to the target refresh rate when the current image refresh rate of the display of the electronic device is different from the target refresh rate. This allows the refresh rate of the display to be adjusted dynamically, thereby reducing the power consumption of the electronic device and achieving energy saving.

[0048] In some embodiments of the present application, based on the target control strategy, a target refresh rate corresponding to the state reference signal and the display signal is determined, such as Figure 2 As shown, the following steps are included:

[0049] Step S1301: determine the current state of the electronic device according to the state reference signal.

[0050] In this embodiment, the current state of the electronic device is determined according to the state reference signal. The current state of the electronic device may be, for example, an idle state, a non-idle state, etc. After the electronic device enters the idle state, the refresh rate of the display may be reduced to reduce power consumption. After the electronic device returns to the non-idle state, the refresh rate of the display may be increased to ensure the display effect of the display.

[0051] Step S1302: when the electronic device is in a target state, determine the target refresh rate based on the display signal.

[0052] If the electronic device is in the target state, the target refresh rate is further determined based on the display signal. By simultaneously considering whether the electronic device has entered the target state and the display signal to determine the target refresh rate, the target refresh rate can be matched with the state of the electronic device and the display signal, thereby improving the accuracy of the target refresh rate.

[0053] It is understandable that if the electronic device is not in the target state, the step of determining the target refresh rate is not performed.

[0054] In some embodiments of the present application, the target state includes a first state and a second state. When the electronic device is in the target state, the target refresh rate is determined based on the display signal, such as Figure 3 As shown, the following steps are included:

[0055] Step S10321: when the electronic device is in the first state and the display signal meets the first target condition, determine the first refresh rate as the target refresh rate.

[0056] In this embodiment, the target refresh rate includes a first refresh rate and a second refresh rate, the first refresh rate is lower than the second refresh rate, and the target state includes a first state and a second state. For example, the first state may be an idle state, which may correspond to a no-operation state and / or a no-user state, and the second state may be a non-idle state, which may correspond to an operation state and / or a user state.

[0057] If the electronic device is in the first state, it is determined whether the display signal meets the first target condition. If the display signal meets the first target condition, it is determined that the display can adopt a lower refresh rate at this time, and the first refresh rate is determined as the target refresh rate, thereby reliably achieving the reduction of power consumption of the electronic device.

[0058] Step S10322: when the electronic device is in the second state and the display signal meets the second target condition, determine the second refresh rate as the target refresh rate, and the first refresh rate is lower than the second refresh rate.

[0059] If the electronic device is in the second state, it is determined whether the display signal meets the second target condition. If the display signal meets the second target condition, it is determined that the display needs to adopt a higher refresh rate at this time, and the second refresh rate is determined as the target refresh rate, so that it can be restored to a higher refresh rate in time, thereby ensuring the display effect of the display.

[0060] It should be noted that the target state of the embodiments of the present application may not be limited to the first state and the second state, and the target refresh rate may not be limited to the first refresh rate and the second refresh rate. Technical personnel in this field may set other target states and other target refresh rates corresponding to other target states as needed, which does not affect the scope of protection of the present application.

[0061] In some embodiments of the present application, the first target condition includes at least one of the following:

[0062] The display signal is an image frame, and the numerical information corresponding to the image frame meets the target numerical value, the numerical information represents the number of target image frames received continuously after the state reference signal is obtained, and the target image frame is an image frame that meets the first refresh rate;

[0063] The display signal is an image frame, and the number of image frames received within a specified time period is not greater than a target number;

[0064] The display signal is a refresh rate control signal, and the refresh rate control signal conforms to the first refresh rate; or,

[0065] The second target condition includes at least one of the following:

[0066] The display signal is an image frame, and the numerical information corresponding to the image frame conforms to the target numerical value, the numerical information represents the number of target image frames received continuously after the state reference signal is obtained, and the target image frame is an image frame conforming to the second refresh rate;

[0067] The display signal is an image frame, and the number of image frames received within a specified time period is greater than a target number;

[0068] The display signal is a refresh rate control signal, and the refresh rate control signal complies with the second refresh rate.

[0069] In this embodiment, if the display signal meets the first target condition, it means that the display can display images at a lower refresh rate at this time. Specifically, the image frame received from the processor can be used as the display signal, and the number of target image frames received continuously after obtaining the state reference signal is determined. If the number meets the target value, it is determined that the display signal meets the first target condition, wherein the target image frame is an image frame that meets the first refresh rate. For example, if the target value is 8, if 8 image frames that meet the first refresh rate are received continuously after obtaining the state reference signal, it is determined that the display signal meets the first target condition. Alternatively, the image frame received from the processor is used as the display signal to determine the number of image frames received within a specified time length. If the number is not greater than the target number, it means that a lower refresh rate can be used at this time, and it is determined that the display signal meets the first target condition. Alternatively, the refresh rate control signal sent by the processor is used as the display signal. If the refresh rate control signal meets the first refresh rate, it is determined that the display signal meets the first target condition. Alternatively, the image frame and refresh rate control signal sent by the processor may be used as the display signal, and if the number of image frames received within the specified time is not greater than the target number, and the refresh rate control signal meets the first refresh rate, it is determined that the display signal meets the first target condition. Alternatively, the image frame and refresh rate control signal sent by the processor may be used as the display signal, and if the numerical information corresponding to the image frame meets the target numerical value, and the refresh rate control signal meets the first refresh rate, it is determined that the display signal meets the first target condition.

[0070] If the display signal meets the second target condition, it means that the display needs to use a higher refresh rate to display the image at this time to ensure a better display effect. Specifically, the image frame received from the processor can be used as a display signal, and the number of target image frames received continuously after obtaining the state reference signal is determined. If the number meets the target value, it is determined that the display signal meets the first target condition, wherein the target image frame is an image frame that meets the second refresh rate. For example, if the target value is 8, if 8 image frames that meet the second refresh rate are received continuously after obtaining the state reference signal, it is determined that the display signal meets the second target condition. In some embodiments of the present application, in order to ensure that the refresh rate of the display is increased in time, the target value corresponding to the second target condition is 1. Alternatively, the image frame received from the processor is used as a display signal to determine the number of image frames received within a specified time length. If the number is greater than the target number, it means that a higher refresh rate is required at this time, and it is determined that the display signal meets the second target condition. Alternatively, the refresh rate control signal sent by the processor is used as a display signal, and if the refresh rate control signal meets the second refresh rate, it is determined that the display signal meets the second target condition. Alternatively, the image frame and refresh rate control signal sent by the processor may be used as the display signal, and if the number of image frames received within the specified time period is greater than the target number, and the refresh rate control signal meets the second refresh rate, it is determined that the display signal meets the second target condition. Alternatively, the image frame and refresh rate control signal sent by the processor may be used as the display signal, and if the numerical value information corresponding to the image frame meets the target numerical value, and the refresh rate control signal meets the second refresh rate, it is determined that the display signal meets the second target condition.

[0071] By setting the first target condition and the second target condition in different ways, the target refresh rate can be determined more flexibly.

[0072] In some embodiments of the present application, Figure 4 As shown, the following steps are also included:

[0073] Step S105 , when the electronic device is in the target state, controlling the display of the electronic device to enter a ready state.

[0074] In this embodiment, controlling the display to enter the ready state may include causing the display to enter the ready state, or, when the execution subject is a display control unit, causing the display control unit to enter the ready state so as to cause the display to enter the ready state, wherein the display can switch to the corresponding target refresh rate faster in the ready state. In some embodiments of the present application, the display control unit can be caused to enter the ready state by changing the value of the target register in the display control unit, thereby causing the display to enter the ready state.

[0075] Specifically, if the target refresh rate includes a first refresh rate and a second refresh rate, then if the target refresh rate is the first refresh rate, the display is controlled to enter a ready state for switching to the first refresh rate. If the target refresh rate is the second refresh rate, the display is controlled to enter a ready state for switching to the second refresh rate.

[0076] Step S106, when the current image refresh rate of the display of the electronic device is different from the target refresh rate, switching the refresh rate of the display to the target refresh rate from the ready state.

[0077] In this embodiment, after the display enters the ready state, the target refresh rate corresponding to the state reference signal and the display signal is determined based on the target control strategy. When the current image refresh rate of the display of the electronic device is different from the target refresh rate, the refresh rate of the display is switched from the ready state to the target refresh rate, thereby achieving more efficient refresh rate switching.

[0078] In some embodiments of the present application, the state reference signal includes at least one of the following:

[0079] an operation state signal of a first target component, wherein the first target component is used to receive a user operation;

[0080] A user status signal is detected by a second target component, where the second target component is used to detect whether there is a user within a target range corresponding to the electronic device.

[0081] In this embodiment, the first target component is used to receive user operations, and the first target component may include one or more components such as a keyboard, a mouse, a light pen, a handwriting input board, a joystick, etc. connected by wired or wireless means. The operation state signal may indicate whether a user operates the electronic device.

[0082] The second target component is used to detect whether there is a user within the target range corresponding to the electronic device, and the second target component may include one or more components such as ultrasonic sensors, radars, infrared sensors, cameras, microphones, etc. The operation status signal may indicate whether there is a user within the target range corresponding to the electronic device.

[0083] Optionally, according to different situations, the operation status signal may be determined as the state reference signal, the user status signal may be determined as the state reference signal, or both the operation status signal and the user status signal may be determined as the state reference signal.

[0084] For example, if the first target component is a mouse and a keyboard, and the second target component is an infrared sensor, if it is detected that no operation is performed on the mouse and the keyboard within a preset time, the target state can be determined to be the first state; if an operation is detected on the mouse and the keyboard, the target state is determined to be the second state. Alternatively, if the infrared sensor detects that the user leaves the electronic device, the target state is determined to be the first state; if the infrared sensor detects that the user returns to the electronic device, the target state is determined to be the second state. Alternatively, if it is detected that no operation is performed on the mouse and the keyboard within a preset time, and the infrared sensor detects that the user leaves the electronic device, the target state is determined to be the first state. If an operation is detected on the mouse and the keyboard, or the infrared sensor detects that the user returns to the electronic device, the target state is determined to be the second state.

[0085] The state reference signal is determined by at least one of the operation state signal of the first target component and the user state signal detected by the second target component, so that the state reference signal accurately represents the current state of the electronic device, thereby more accurately determining the target refresh rate.

[0086] In some embodiments of the present application, the signal acquisition unit includes a first signal acquisition unit and a second signal acquisition unit, and obtaining the state reference signal sent by the signal acquisition unit of the electronic device includes at least one of the following:

[0087] receiving the operation state signal from the first signal acquisition unit through a first communication link, and determining the operation state signal as the state reference signal;

[0088] The user status signal is received from the second signal acquisition unit through a second communication link, and the user status signal is determined as the status reference signal.

[0089] In this embodiment, the signal acquisition unit includes a first signal acquisition unit and a second signal acquisition unit. The first signal acquisition unit is connected to the first target component and can output the operation status signal of the first target component through the first communication link. The second signal acquisition unit is connected to the second target component and can output the user status signal detected by the second target component through the second communication link. The operation status signal received from the first signal acquisition unit can be determined as a state reference signal, and the user status signal output from the second signal acquisition unit can be determined as a state reference signal. The operation status signal received from the first signal acquisition unit and the user status signal output from the second signal acquisition unit can also be determined as a state reference signal, thereby achieving more flexible and efficient acquisition of the state reference signal.

[0090] In a specific application scenario, the first signal acquisition unit may be an embedded controller (i.e., EC), and the first communication link may be an SMBus (System Management Bus).
