Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of wearable devices, and more particularly, to a screen switching method of a wearable device, a screen switching apparatus of a wearable device, a wearable device, and a computer-readable storage medium. BACKGROUND

[0002] In recent years, wearable devices have developed rapidly. In the case that a user uses a wearable device such as a smart watch, the user needs to check the time at any time and anywhere, and thus it is inevitable to keep the display screen of the smart watch in a constant display state. Most of the smart watches on the market basically use a wrist-lifting bright screen mode to meet the user's need to check the time. Although this design can maximize the battery life, if too many background applications of the smart watch are running or the smart watch is used for a long time, the time for lifting the wrist to brighten the screen will increase, so that the user cannot check the time in the first time, which affects the user experience.

[0059] Figure 1 The wearable device shown is merely illustrative and is by no means intended to limit the present disclosure, its application or use.

[0060] <Method Embodiment>

[0061] Figure 2 A screen switching method of a wearable device according to one embodiment of the present disclosure is shown, which can be implemented by, for example, Figure 1 The wearable device 1000 shown can be a smart watch, a smart bracelet, etc. The wearable device includes a first display system and a second display system, and the power consumption of the second display system is less than that of the first display system.

[0062] As shown in Figure 2 The screen switching method of the wearable device provided in the present embodiment can include the following steps S2100-S2300.

[0063] In step S2100, in a case where the display screen of the wearable device is controlled by the first display system, a sleep instruction that the first display system needs to enter a sleep state is sent to the second display system by the first display system in response to a set sleep event.

[0064] The first display system can be an application processor (AP), which can be a system on a chip (SOC). The second display system can be a microcontroller unit (MCU), and the power consumption of the MCU is less than that of the AP. In this embodiment, when the display screen is controlled by the second display system, the display screen automatically enters an always-on display (AOD) mode, and the watch face area is kept on.

[0065] The display screen can be an organic electroluminescence display (OLED).

[0066] The set sleep event can be a set sleep time, which can be 15 seconds, 30 seconds, 1 minute, 2 minutes, 5 minutes, or 10 minutes. In one specific embodiment, the wearable device is provided with a setting control for setting the state of the display screen, for example, including a first setting control for setting the sleep time of the display screen in the AOD mode. For example, a second setting control is provided for setting the sleep time of the display screen in the non-AOD mode.

[0067] Optionally, when the first setting control is in an on state and the sleep time is set by the first setting control, if the display screen of the wearable device is controlled by the AP, when the display screen of the wearable device does not receive an input event within the sleep time, it indicates that the AP triggers a timeout sleep and needs to switch to the MCU. Here, the AP sends a sleep instruction to the MCU that the AP needs to enter a sleep state.

[0068] Optionally, when the second setting control is in an on state and the sleep time is set by the second setting control, if the display screen of the wearable device is controlled by the AP, when the display screen of the wearable device does not receive an input event within the sleep time, the AP enters a sleep state, and the display screen normally turns off.

[0069] In a specific embodiment, the communication between the micro control unit MCU and the application processor AP is implemented based on the SPI (Serial Peripheral Interface) protocol. Specifically, the upper layer on the application processor AP side sends the encapsulated data, such as the sleep signal, to the real-time operating system kernel of the application processor AP, and the real-time operating system kernel of the application processor AP sends the agreed protocol bytes based on the SPI protocol to the micro control unit MCU, and waits to receive the first response instruction that the micro processing unit MCU can enter the sleep state in reply.

[0070] Step S2200, receiving, by the first display system, the first response instruction returned by the second display system in response to the sleep instruction.

[0071] The first response instruction is used to indicate that the first display system can enter the sleep state and can be switched to the second display system.

[0072] In this embodiment, after the micro processing unit MCU receives the sleep instruction sent by the application processor AP, the micro processing unit MCU can stop reporting the step counting data to the application processor AP in response to the sleep instruction, and send the first response instruction to the application processor AP, indicating that the application processor AP can enter the sleep state and can be switched to the micro control unit MCU.

[0073] Step S2300, in response to the first response instruction, controlling the first display system to enter the sleep state, and controlling the display screen to display the watch face through the second display system.

[0074] In this embodiment, when the display screen is controlled by the micro control unit MCU, the display screen automatically enters the AOD mode, keeps the watch face area constantly displayed, and ensures that the user can view the time in real time. Moreover, when the application processor AP is in sleep, the display screen can be taken over by the micro control unit MCU with lower power consumption, so that the wearable device can ensure low power consumption and does not affect the endurance while keeping the watch face area of the display screen of the wearable device constantly displayed.

[0075] In a specific embodiment, the step S2300 of controlling the first display system to enter the sleep state and displaying the watch face through the second display system in response to the first response instruction can further include the following steps S2310-S2340:

[0076] Step S2310, in response to the first response instruction, controlling the signal controller to switch to the second display system, and sending a screen takeover instruction to the second display system, which takes over the display screen.

[0077] In one example, after the application processor AP receives the first response instruction sent by the micro control unit MCU, the application processor AP can control the signal controller to switch to the micro control unit MCU, and send a screen takeover instruction to the micro control unit MCU, where the signal controller can be a MIPI (Mobile Industry Processor Interface) controller.

[0078] In one example, after the first display system (application processor AP) receives the first response instruction sent by the second display system (micro control unit MCU), before the first display system controls the signal controller to switch to the second display system and sends a screen takeover instruction to the second display system, the first display system can also control the display screen to enter an ultra-low power state (ULPS) in response to the first response instruction, so that the switching of the display screen in the ULPS can not only maintain the frame image before the switching of the display screen, but also avoid the collapse of the wearable device.

[0079] In step S2320, the second display system receives the screen takeover instruction, and controls the display screen to display the watch face in response to the screen takeover instruction.

[0080] In one example, after the micro control unit MCU receives the screen takeover instruction, the micro control unit MCU can display the watch face, at this time, the display screen enters the AOD mode, and the watch face area is always on, which is convenient for the user to view the time in real time.

[0081] In one example, after the display screen has entered the ultra-low power state (ULPS), after the second display system receives the screen takeover instruction, the second display system can first control the display screen to exit the ultra-low power state (ULPS) in response to the screen takeover instruction, and then control the micro control unit MCU to display the watch face.

[0082] In this step S2320, after the micro control unit MCU controls the display screen to display the watch face, the micro control unit MCU sends a second response instruction of switching success to the application processor AP.

[0083] In step S2330, the first display system receives the second response instruction of switching success sent by the second display system.

[0084] In this step S2320, after the application processor AP receives the second response instruction, the application processor AP can enter a sleep process to ensure that the application processor AP normally enters the sleep state.

[0085] Step S2340, in response to the second response instruction, the first display system enters a sleep state.

[0086] According to the embodiments of the present disclosure, the wearable device includes the first display system and the second display system, and the power consumption of the second display system is less than that of the first display system. In the normal use of the wearable device, the display screen of the wearable device is controlled by the first display system. When the first display system is in sleep, the second display system can be switched to control the display screen to display the watch face. That is, when the first display system is in sleep, the second display system with lower power consumption can take over the display screen to display the watch face, which facilitates the user to view in real time, and ensures the power consumption of the wearable device, and does not affect the endurance.

[0087] In one embodiment, the first display system and the second display system have the same display parameters; wherein the display parameters include at least one of screen resolution and screen refresh rate.

[0088] It can be understood that, in order to meet the normal switching and smoothness when the application processor AP and the micro control unit MCU control the display screen, the same display parameters need to be configured between the application processor AP and the micro control unit MCU, for example, including screen resolution, screen refresh rate, and can also include working mode of the display screen, and power-on and power-off distinction of AOD mode and non-AOD mode.

[0089] According to the embodiments, the same display parameters are set for the first display system and the second display system, which can avoid the problems of lag, flashing and smoothness during switching.

[0090] In one embodiment, when the application processor AP needs to be woken up, the screen switching method of the embodiments of the present disclosure can further include the following steps S3100-S3300:

[0091] Step S3100, in the case of displaying the watch face by the second display system, the first display system sends a screen takeover request of taking over the display screen by the first display system to the second display system.

[0092] In this embodiment, the wearable device is provided with a wake-up source for a user to wake up the application processor AP, which can include, but is not limited to, a power key, an incoming call, and a sedentary reminder. For example, in the case that the user presses the power key, it indicates that the application processor AP receives a wake-up event, at which time the application processor AP needs to be woken up to control the display screen through the application processor AP. For another example, in the case that the wearable device receives an incoming call, at which time the application processor AP needs to be woken up to control the display screen through the application processor AP. For still another example, in the case that the sedentary reminder function is in an on state, when the sedentary reminder time arrives, at which time the application processor AP needs to be woken up to control the display screen through the application processor AP.

[0093] In this embodiment, when the application processor AP receives a wake-up event, it further determines whether the display screen is in the AOD mode. If it is in the AOD mode, the micro control unit MCU is sent a screen takeover request for the display screen to be taken over by the application processor AP. If it is not in the AOD mode, the display screen is directly controlled by the application processor AP.

[0094] In one example, after the first display system sends a screen takeover request for the display screen to be taken over by the first display system to the second display system, the second display system can release the control of the display screen and return a third response instruction to the first display system.

[0095] In one example, after the first display system sends a screen takeover request for the display screen to be taken over by the first display system to the second display system, the second display system can first control the display screen to enter an ultra-low power consumption (ULPS) mode, then release the control of the display screen, and return a third response instruction to the first display system.

[0096] Step S3200: receiving, by the first display system, a third response instruction returned by the second display system in response to the screen takeover request.

[0097] Step S3300: controlling, by the first display system, the display screen in response to the third response instruction.

[0098] In this embodiment, the step S3300 of controlling, by the first display system, the display screen in response to the third response instruction can further include the following steps S3310-S3330:

[0099] Step S3310: in response to the third response instruction, controlling the signal controller to switch to the first display system and sending a wake-up instruction to the second display system that the first display system is woken up.

[0100] In step S3310, after the application processor AP receives the third response instruction sent by the microcontroller unit MCU, it controls the signal controller to switch to the application processor AP and sends a wake-up instruction to the microcontroller unit MCU to wake up the application processor AP. After receiving the wake-up instruction, the microcontroller unit MCU sends a fourth response instruction to switch to the application processor AP and reports step counting data to the application processor AP normally.

[0101] The signal controller may be a MIPI (Mobile Industry Processor Interface) controller.

[0102] Step S3320: Receive a fourth response instruction returned by the second display system in response to the wake-up instruction; wherein the fourth response instruction is used to indicate that the system can be switched to the first display system.

[0103] Step S3330: In response to the fourth response instruction, control the display screen through the first display system.

[0104] In one example, after receiving the fourth response instruction, the application processor AP may control the display screen to display the image normally.

[0105] In one example, when the display screen has entered UPLS mode, after receiving the fourth response instruction, it can respond to the fourth response instruction by first controlling the display screen to exit the ultra-low power consumption (ULPS) mode through the first display system, and then controlling the display screen through the first display system.

[0106] It's understandable that the screen displayed on the application processor (AP) must also be synchronized to avoid displaying the previous frame before it went into sleep. For example, if the second hand on the watch face is at 5s before the AP goes into sleep, and then wakes up after 20 seconds of sleep, it should normally be at 25s, rather than jumping directly from 5s to 25s.

[0107] <Example 1>

[0108] Next, we will take the example of triggering the application processor AP to sleep and switching to the microcontroller unit MCU to control the display screen. Figure 3 As shown, the screen switching method of the wearable device may further include:

[0109] Step S411: The application processor AP triggers timeout sleep.

[0110] In step S412 , the communication between the application processor AP and the micro control unit MCU is completed based on the SPI protocol, and the application processor AP sends a sleep signal to the micro control unit MCU.

[0111] Step S421, the micro control unit MCU receives the sleep signal, stops the step counting data reporting, and the application processor AP sends a first response instruction.

[0112] Step S413, the application processor AP receives the first response instruction.

[0113] Step S414, the application processor AP controls the display screen to enter the ULPS mode.

[0114] Step S415, the application processor AP switches the MIPI controller to the micro control unit MCU.

[0115] Step S416, the application processor AP sends a screen takeover instruction for the micro control unit MCU to take over the display screen.

[0116] Step S422, the micro control unit MCU receives the screen takeover instruction, controls the display screen to exit the UPLS mode, and controls the display screen to enter the constant display mode to display the watch face, and sends a second response instruction of switching success to the application processor AP.

[0117] Step S416, the application processor AP receives the second response instruction, enters the sleep flow, and ensures that the application processor AP is in the sleep state.

[0118] <Example 2>

[0119] Next, taking the case of waking up the application processor AP and needing to switch to the application processor AP to control the display screen as an example, referring to FIG. 5, the screen switching method of the wearable device can further include: Figure 4

[0120] Step S511, in the case that the application processor AP receives a wake-up event, the application processor AP detects whether the display screen is in the AOD mode. If yes, go to step S512, otherwise, normally display the screen.

[0121] Step S512, the application processor AP sends a screen takeover request to the micro control unit MCU for the application processor AP to take over the display screen.

[0122] Step S521, the micro control unit MCU receives the screen takeover request, controls the display screen to enter the ULPS mode, and sends a third response instruction to the application processor AP that the micro control unit MCU has released the control right of the display screen.

[0123] Step S513, the application processor AP receives the third response instruction, and switches the MIPI controller to the application processor AP.

[0124] ​Step S514, the application processor AP sends a wake-up instruction to the micro control unit MCU that the application processor AP is woken up.

[0125] Step S522, the micro control unit MCU receives the wake-up instruction, sends a fourth response instruction to the application processor AP indicating that the application processor AP can be switched to, and reports the step counting data.

[0126] Step S515, the application processor AP receives the fourth response instruction, controls the display screen to exit the UPLS mode, and controls the display screen to display a picture.

[0127] <Device Embodiment>
