It is widely used in display devices such as smart bracelets.

Summary of the Invention

[0003] To overcome the problems existing in related technologies, this disclosure provides a display control method, processor, device, medium, program product, and chip.

[0004] According to a first aspect of the present disclosure, a display control method is provided, applied to a processor, the processor including a control module, a computing module, and a display processing module, the display control method comprising: The control module periodically determines the interface adjustment information corresponding to the electronic clock interface at a preset frequency, and sends the interface adjustment information and calculation instructions to the calculation module. The interface adjustment information includes the rotation angle information of the target pointer of the electronic clock interface. The calculation module responds to the calculation instruction and determines the target display information of the electronic clock interface based on the interface adjustment information and the initial display information of the electronic clock interface; The display processing module controls the display screen to refresh the electronic clock interface based on the target display information.

[0005] In this embodiment, the control module determines interface adjustment information and sends the interface adjustment information and calculation instructions to the calculation module. Upon receiving the calculation instructions, the calculation module determines the target display information based on the interface adjustment information and the initial display information. Then, the display processing module controls the display screen to refresh the electronic clock interface based on the target display information, thus achieving display refresh control of the electronic clock interface. This ensures that the electronic clock interface can continuously provide users with accurate time information to meet their time viewing needs. By setting up a control module, a calculation module, and a display processing module in the processor, each serving as an independent module with a single responsibility for scheduling control, data processing, and display refresh control, respectively, it ensures that each module can achieve display control of the electronic clock interface with simple algorithms and hardware deployment. This reduces the power consumption and resource consumption of the electronic clock interface display refresh process, which is beneficial for simultaneously meeting the requirements for smooth and diverse display effects as well as battery life, thereby improving the user experience.

[0006] In some embodiments of this disclosure, the electronic clock interface includes multiple pointer layers, with different target pointers corresponding to different pointer layers.

[0007] In this embodiment, the electronic clock interface is configured as multiple pointer layers, with different target pointers corresponding to different pointer layers. This enables independent and precise control of each target pointer, which helps reduce the difficulty of software development and hardware deployment of the electronic clock interface. It also facilitates personalized design, functional expansion, and effect optimization of the electronic clock interface, further enhancing the user experience.

[0008] In some embodiments of this disclosure, determining the target display information of the electronic clock interface based on the interface adjustment information and the initial display information of the electronic clock interface includes: Based on the interface adjustment information and the initial display information corresponding to each pointer layer, the target display information corresponding to each pointer layer is determined; The step of controlling the display screen to refresh the electronic clock interface based on the target display information includes: Based on the target display information corresponding to each pointer layer, generate each refreshed pointer layer; Based on the refreshed pointer layers, the screen is generated and controlled to display the refreshed electronic clock interface.

[0009] In this embodiment, the target display information corresponding to each pointer layer is determined based on the interface adjustment information and initial display information corresponding to each pointer layer. Then, based on the target display information, refreshed pointer layers are generated. Finally, based on the refreshed pointer layers, the display screen is generated and controlled to show the refreshed electronic clock interface. The complete refresh of the electronic clock interface is achieved through independent layer refresh and composite display. This allows each target pointer to independently execute the process of determining the target display information and the layer refresh process, avoiding interference between data processing or layer refresh processes of different target pointers. This further reduces the computational load and hardware burden on the calculation module and display processing module, facilitating personalized design, functional expansion, and effect optimization of the electronic clock interface, and further enhancing the user experience.

[0010] In some embodiments of this disclosure, different target pointers correspond to different preset frequencies.

[0011] In this embodiment, by configuring different preset frequencies for different target pointers, different target pointers can correspond to different refresh frequencies according to their needs, which can further realize independent and precise control of each target pointer, and help reduce the amount of computation and power consumption in the display control process.

[0012] In some embodiments of this disclosure, the rotation angle information includes at least one of the rotation angle of the target pointer, the trigonometric function value corresponding to the rotation angle, and the fixed-point value of the trigonometric function corresponding to the rotation angle.

[0013] In this embodiment, at least one of the rotation angle of the target pointer, the trigonometric function value corresponding to the rotation angle, and the fixed point value of the trigonometric function corresponding to the rotation angle is used as the rotation angle information, which provides a basis for determining the target display information and refreshing the electronic clock interface. It can utilize the characteristics of data forms such as rotation angle, trigonometric function value, and trigonometric function fixed point value to optimize the display control process, which is beneficial to reducing the amount of calculation and power consumption of the display control process.

[0014] In some embodiments of this disclosure, the interface adjustment information further includes at least one of the following: the read address of the initial display information, the storage address of the target display information, the image size of the electronic clock interface, and the interrupt instruction configuration parameters.

[0015] In this embodiment, at least one of the following is used together with the rotation angle information: the reading address of the initial display information, the storage address of the target display information, the image size of the electronic clock interface, and the interrupt instruction configuration parameters. This provides a guarantee for the determination of the target display information and its subsequent use, which is beneficial to improving the efficiency and stability of the display control process.

[0016] In some embodiments of this disclosure, the interface adjustment information further includes interrupt instruction configuration parameters, and the display control method further includes: In response to determining the target display information, the calculation module generates an interrupt command based on the interrupt command configuration parameters and sends it to the control module. In response to the interrupt command, the control module generates a display command and display configuration parameters and sends them to the display processing module.

[0017] In this embodiment, when the interface adjustment information also includes interrupt command configuration parameters, the calculation module generates an interrupt command based on the interrupt command configuration parameters and sends it to the control module when determining the target display information. This notifies the control module that the determination of the target display information has been completed. When the control module receives the interrupt command, it generates a display command and display configuration parameters and sends them to the display processing module. This provides an indication and basis for the display processing module to control the display screen to refresh the electronic clock interface, realizing the scheduling and control of the display processing module, which is beneficial to improving the efficiency and stability of the display control process.

[0018] In some embodiments of this disclosure, the initial display information includes the initial pixel information of each pixel of the electronic clock interface; Determining the target display information of the electronic clock interface based on the interface adjustment information and the initial display information of the electronic clock interface includes: The pixels of the electronic clock interface are divided into a first pixel corresponding to the target pointer and a second pixel other than the first pixel; Based on the initial pixel information of each first pixel and the interface adjustment information, the target pixel information of each first pixel is determined; The target display information is determined based on the target pixel information of each first pixel and the initial pixel information of each second pixel.

[0019] In this embodiment, the pixels of the electronic clock interface are divided into a first pixel corresponding to the target pointer and a second pixel other than the first pixel. Based on the initial pixel information of each first pixel and interface adjustment information, the target pixel information of each first pixel is determined. Then, based on the target pixel information of each first pixel and the initial pixel information of each second pixel, the target display information is determined, providing a basis for refreshing the electronic clock interface. By selecting the first pixel related to the target pointer for calculating the target pixel information, the calculation of the second pixels unrelated to the electronic clock interface can be directly skipped, significantly reducing the actual computational load of the calculation module and further reducing power consumption and resource consumption during the display refresh process.

[0020] In some embodiments of this disclosure, the first pixel is configured as a pixel whose transparency channel value is greater than 0.

[0021] In this embodiment, pixels with a transparency channel value greater than 0 are used as the first pixel, enabling the calculation module to quickly and accurately divide the first pixel into the second pixel, further reducing the actual computational load of the calculation module, thereby reducing the power consumption and resource consumption of the display refresh process.

[0022] In some embodiments of this disclosure, the initial pixel information includes the initial position information of the pixel; Determining the target pixel information of each first pixel based on the initial pixel information of each first pixel and the interface adjustment information includes: Based on the initial position information of each first pixel and the interface adjustment information, the target position information of each first pixel is determined as the target pixel information of each first pixel.

[0023] In this embodiment, the initial position information of the pixel is used as the initial pixel information. Based on the initial position information of each first pixel and the interface adjustment information, the target position information of each first pixel is determined and used as the target pixel information of each first pixel. The rotation of the target pointer can be reflected by the position adjustment of the first pixel, so as to provide a basis for determining the target display information and refreshing the electronic clock interface. The calculation method is simple and has a small error, which improves the efficiency and accuracy of determining the target display information.

[0024] In some embodiments of this disclosure, the display control method further includes: In response to enabling the always-on display mode, the display processing module controls the display screen to display the electronic clock interface.

[0025] In this embodiment, when the always-on display mode is detected, the display processing module controls the display screen to display the electronic clock interface, so that the electronic clock interface can start displaying when the always-on display mode is enabled and refresh in real time during the always-on display mode. Since the control module, computing module and display processing module can reduce the power consumption and resource consumption of the display refresh process, which matches the requirements of the always-on display mode for low power consumption and low resource consumption, there is no need for high-power processors such as GPUs or APs to participate in the display control process during the always-on display mode.

Detailed Implementation

[0049] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0050] In recent years, with the rapid development of display technology and the continuous iteration of display devices, always-on display technology, also known as screen-off display technology, has been widely used in display devices such as smart bracelets, mobile phones, and smart home appliances due to its advantages of improving information acquisition efficiency, ensuring energy saving and battery life, and enabling personalized interaction. An electronic clock interface is a display interface that simulates a physical pointer dial. It can display time information to users as the content displayed when the screen is off, and can meet users' needs for time viewing through refresh control, function expansion, and customized design of the electronic clock interface.

[0051] In related technologies, the display refresh of an electronic clock interface can be achieved through the rendering capabilities of a Graphics Processing Unit (GPU). However, when using a GPU to control the display refresh of an electronic clock interface, a full-frame refresh frequency of 60 times per second or higher is required. This large amount of redundant data not only consumes memory bandwidth but also leads to excessive power consumption, which will negatively impact the battery life of the display device. Using pre-rendering requires reserving a large amount of storage space, resulting in poor applicability and high hardware costs. Using low-performance processing devices cannot guarantee the smoothness of the electronic clock interface display and is difficult to adapt to specific shapes or styles, limiting the personalized design of the electronic clock interface.

[0052] Based on this, this disclosure provides a display control method. The control module determines interface adjustment information and sends the interface adjustment information and calculation instructions to the calculation module. Upon receiving the calculation instructions, the calculation module determines the target display information based on the interface adjustment information and the initial display information. Then, the display processing module controls the display screen to refresh the electronic clock interface according to the target display information, thus realizing the display refresh control of the electronic clock interface. This ensures that the electronic clock interface can continuously provide users with accurate time information to meet their time viewing needs. By setting the control module, calculation module, and display processing module in the processor, each serving as an independent module with a single responsibility for scheduling control, data processing, and display refresh control, it is ensured that each module can achieve display control of the electronic clock interface with simple algorithms and hardware deployment. This reduces the power consumption and resource occupation of the electronic clock interface display refresh process, which is beneficial for simultaneously meeting the requirements for smooth and diverse display effects as well as battery life, thereby improving the user experience.

[0053] In one exemplary embodiment, a display control method is provided, applied to, for example... Figure 1 The processor shown is an electronic device, such as a wristband, mobile phone, or smart home appliance, equipped with a processor and display function. The processor includes a control module 10, a computing module 20, and a display processing module 30. Both the computing module 20 and the display processing module 30 are communicatively connected to the control module 10. Exemplarily, the processor may include a system-on-a-chip (SOC) integrating the above modules as a hardware architecture for executing the display control process. The processor can be deployed together with the display screen in the electronic device and control the display screen through the display processing module. (Reference) Figure 2 As shown, the display control method includes: S100: The control module periodically determines the interface adjustment information corresponding to the electronic clock interface at a preset frequency, and sends the interface adjustment information and calculation instructions to the calculation module. The interface adjustment information includes the rotation angle information of the target pointer of the electronic clock interface.

[0054] In step S100, the display processing module 30 controls the display screen to show an electronic clock interface. The electronic clock interface may include a dial and multiple target hands to provide time information to the user. The control module 10 periodically determines the interface adjustment information of the electronic clock interface at a preset frequency. This adjustment information includes the rotation angle information of the target hands, reflecting the angle each target hand needs to rotate during the next refresh, serving as the basis for subsequent display refreshes. After determining the interface adjustment information, the control module 10 sends the adjustment information and calculation instructions to the calculation module 20. The control module 10 only needs to handle the scheduling and control of the electronic clock interface, allowing it to ensure efficient and stable execution of the display control process with a low wake-up frequency, short runtime, and low power consumption.

[0055] For example, the calculation module 20 may include a microcontroller unit (MCU), and a real-time clock (RTC) that generates a hardware interrupt at a preset frequency of once per second to start the control module 10. The control module 10 reads the current precise time from the real-time clock register and calculates the rotation angles of the second and minute hands according to the time interval between the current precise time and the last refresh of the electronic clock interface. The rotation angles of the second and minute hands can be determined at 6° per second and 6° per minute, respectively. The determined rotation angle information and the generated calculation instructions are then sent to the register of the calculation module 20.

[0056] S200: The calculation module responds to the calculation command and determines the target display information of the electronic clock interface based on the interface adjustment information and the initial display information of the electronic clock interface.

[0057] In step S200, the electronic clock interface has corresponding display information to serve as data support for displaying the electronic clock interface, which can determine the display content of the electronic clock interface. The initial display information of the electronic clock interface is the display information corresponding to the last refresh of the electronic clock interface, which can reflect the angle of each target hand at the last refresh of the electronic clock interface. The interface adjustment information can reflect the angle that each target hand needs to rotate at the next refresh of the electronic clock interface. The angle of each target hand after the next refresh can be calculated based on the two.

[0058] Therefore, when the calculation module 20 receives the calculation command and interface adjustment information sent by the control module 10, it can determine the target display information of the electronic clock interface according to the trigger indication of the calculation command and the interface adjustment information and initial display information of the electronic clock interface. This target display information reflects the display content of the electronic clock interface after the next refresh, providing a basis for refreshing the electronic clock interface. The calculation module 20 only needs to handle the data processing of the electronic clock interface, allowing the control module 10 to ensure efficient and stable execution of the display control process with a lower wake-up frequency, shorter runtime, and lower power consumption.

[0059] For example, the calculation module 20 may include a Vector Digital Signal Processor (VDSP). The calculation module 20 can read the initial display information from the buffer, perform pixel-by-pixel filtering and rotation processing on the initial display information according to the rotation angle of the target pointer reflected by the interface adjustment information to obtain the target display information, and store the target display information in the buffer. S300, the display processing module controls the display screen to refresh the electronic clock interface based on the target display information.

[0060] In step S300, the display processing module 30 has image generation capabilities such as layer compositing. Based on the target display information, it generates image data corresponding to the electronic clock interface after the target pointer rotates, and sends the data to the display screen for display, thereby controlling the display screen to refresh the electronic clock interface. This allows the user to view the precise time in real time through the continuously refreshed electronic clock interface. The display processing module 30 only needs to be responsible for controlling the display refresh of the electronic clock interface, enabling it to ensure efficient and stable execution of the display control process through a low wake-up frequency, short runtime, and low power consumption.

[0061] For example, the display processing module 30 may include a display processing unit (DPU). The display processing module 30 can automatically generate the corresponding image according to the target display information through its hardware logic, and transmit the image to the display screen through the display buffer area and the display serial interface (DSI), and control the display screen to display the image to complete the refresh of the electronic clock interface.

[0062] In this embodiment, the control module 10 determines the interface adjustment information and sends the interface adjustment information and calculation instructions to the calculation module 20. Upon receiving the calculation instructions, the calculation module 20 determines the target display information based on the interface adjustment information and the initial display information. Then, the display processing module 30 controls the display screen to refresh the electronic clock interface based on the target display information, thus achieving display refresh control of the electronic clock interface. This ensures that the electronic clock interface continuously provides accurate time information to the user, meeting the user's time viewing needs. By setting the control module 10, calculation module 20, and display processing module 30 in the processor, each serving as an independent module with a single responsibility for scheduling control, data processing, and display refresh control, it ensures that each module can achieve display control of the electronic clock interface with simple algorithms and hardware deployment. This reduces the power consumption and resource consumption of the electronic clock interface display refresh process, which is beneficial for simultaneously meeting the requirements for smooth and diverse display effects as well as battery life, thereby improving the user experience.

[0063] In some embodiments, the electronic clock interface includes multiple pointer layers, with different target pointers corresponding to different pointer layers.

[0064] Multiple pointer layers constitute all or part of the electronic clock interface, and different target pointers are located on different pointer layers, so that each target pointer and each pointer layer has corresponding interface adjustment information, initial display information and target display information. Each target pointer can independently execute the process of determining the target display information, which can reduce the amount of calculation of the target display information per time and avoid mutual interference in the data processing processes of different target pointers.

[0065] For example, the electronic clock interface may include a dial layer, an hour hand layer, a minute hand layer, and a second hand layer. The dial layer can be a static layer, and the electronic clock interface can be refreshed by refreshing the hour hand layer, minute hand layer, and second hand layer. Alternatively, the electronic clock interface may include an hour hand layer, a minute hand layer, and a second hand layer. The hour hand layer includes a static dial and a pre-rendered hour hand, which does not need to be refreshed in real time. The refresh of the electronic clock interface can be achieved by refreshing the minute hand layer and the second hand layer.

[0066] In this embodiment, the electronic clock interface is configured as multiple pointer layers, with different target pointers corresponding to different pointer layers. This enables independent and precise control of each target pointer, which helps reduce the difficulty of software development and hardware deployment of the electronic clock interface. It also facilitates personalized design, functional expansion, and effect optimization of the electronic clock interface, further enhancing the user experience.

[0067] In some embodiments, determining the target display information of the electronic clock interface based on interface adjustment information and initial display information of the electronic clock interface includes: determining the target display information corresponding to each pointer layer based on the interface adjustment information and initial display information corresponding to each pointer layer.

[0068] Since different target pointers are located in different pointer layers, each target pointer and each pointer layer has corresponding interface adjustment information, initial display information, and target display information. For each target pointer and its corresponding pointer layer that needs to be refreshed, the target display information corresponding to that pointer layer needs to be determined based on the interface adjustment information and initial display information of that pointer layer.

[0069] refer to Figure 3 As shown, based on the target display information, the display screen is controlled to refresh the electronic clock interface, including: S310. Based on the target display information corresponding to each pointer layer, generate each refreshed pointer layer.

[0070] S320 generates and controls the display screen to show the refreshed electronic clock interface based on the refreshed pointer layers.

[0071] In steps S310 and S320, after obtaining the target display information corresponding to each pointer layer, for each pointer layer, the display processing module 30 can use its image generation capability to generate a refreshed pointer layer based on the target display information, enabling the corresponding target pointer to rotate within the refreshed pointer layer. Then, the display processing module 30 uses its layer compositing capability to composite the refreshed pointer layers to obtain the refreshed electronic clock interface, and controls the display screen to display the refreshed electronic clock interface, thereby achieving a complete refresh of the electronic clock interface.

[0072] In this embodiment, the target display information corresponding to each pointer layer is determined based on the interface adjustment information and initial display information corresponding to each pointer layer. Based on the target display information corresponding to each pointer layer, the refreshed pointer layers are generated. Then, based on the refreshed pointer layers, the display screen is generated and controlled to display the refreshed electronic clock interface. The complete refresh of the electronic clock interface is achieved through the independent refresh and composite display of the layers. This allows each target pointer to independently execute the process of determining the target display information and the layer refresh process, avoiding mutual interference between the data processing or layer refresh processes of different target pointers. This further reduces the computational load and hardware load of the calculation module 20 and the display processing module 30, making it easier to realize the personalized design, functional expansion and effect optimization of the electronic clock interface, and further improving the user experience.

[0073] In some embodiments, each target pointer corresponds to the same preset frequency, so that each target pointer needs to refresh the pointer layer at the same frequency, that is, each target pointer is synchronously adjusted every time the electronic clock interface is refreshed.

[0074] In other embodiments, different target pointers correspond to different preset frequencies.

[0075] Different preset frequencies can be configured for different target hands, allowing each target hand to refresh its corresponding hand layer at a different preset frequency. Each time the electronic clock interface is refreshed, some target hands rotate and change, while others remain relatively stationary. The preset frequency for each target hand can be adaptively set or adjusted as needed, ensuring that the refresh frequency of the target hand matches its corresponding rotation rate. For example, a preset frequency of once per second can be configured for the second hand, once per minute for the minute hand, and once per hour for the hour hand.

[0076] In this embodiment, by configuring different preset frequencies for different target pointers, different target pointers can correspond to different refresh frequencies according to their needs, which can further realize independent and precise control of each target pointer, and help reduce the amount of computation and power consumption in the display control process.

[0077] In some embodiments, the rotation angle information includes at least one of the following: the rotation angle of the target pointer, the trigonometric function value corresponding to the rotation angle, and the fixed-point value of the trigonometric function corresponding to the rotation angle.

[0078] At least one of the rotation angle of the target pointer, the trigonometric function value corresponding to the rotation angle, and the fixed point value of the trigonometric function corresponding to the rotation angle can be used as the rotation angle information included in the interface adjustment information, so as to reflect the angle that each target pointer needs to rotate when the electronic clock interface is refreshed next, providing a basis for determining the target display information and refreshing the electronic clock interface.

[0079] The rotation angle of the target pointer is the actual angle value without processing or conversion, which can be calculated based on the time interval between the current precise time and the last refresh of the electronic clock interface. The trigonometric function value corresponding to the rotation angle is the result of the trigonometric function operation on the rotation angle, such as a sine function value or a cosine function value, which can be directly used for subsequent pixel rotation calculations to determine the target display information and reduce the computational load of the calculation module 20. The fixed-point value of the trigonometric function is the fixed-point number obtained after multi-bit integer amplification of the trigonometric function value, which can reduce the power consumption generated by floating-point operations. For example, the rotation angle of the target pointer is θ, and the trigonometric function values ​​corresponding to the rotation angle are sin(θ) and cos(θ). The fixed-point values ​​of the trigonometric functions sin_val and cos_val corresponding to the rotation angle can be determined by the following formulas (1) and (2): sin_val=2 N ×sin(θ) (1) cos_val=2 N ×cos(θ) (2) N is a positive integer greater than 0.

[0080] It is understandable that, since the trigonometric function values ​​and trigonometric function fixed-point values ​​corresponding to the rotation angle have a fixed correspondence with the rotation angle, a trigonometric function value lookup table or a trigonometric function fixed-point value lookup table can be configured in the control module 10. The trigonometric function values ​​and trigonometric function fixed-point values ​​can be determined by indexing without real-time calculation, which is conducive to further improving the efficiency of determining the interface adjustment information.

[0081] In this embodiment, at least one of the rotation angle of the target pointer, the trigonometric function value corresponding to the rotation angle, and the fixed point value of the trigonometric function corresponding to the rotation angle is used as the rotation angle information, which provides a basis for determining the target display information and refreshing the electronic clock interface. It can utilize the characteristics of data forms such as rotation angle, trigonometric function value, and trigonometric function fixed point value to optimize the display control process, which is beneficial to reducing the amount of calculation and power consumption of the display control process.

[0082] In some embodiments, the interface adjustment information may further include at least one of the following: the read address of the initial display information, the storage address of the target display information, the image size of the electronic clock interface, and the interrupt instruction configuration parameters.

[0083] The control module 10 can send at least one of the following parameters—the initial display information read address, the target display information storage address, the image size of the electronic clock interface, and the interrupt instruction configuration parameters—along with the rotation angle information, to the register of the calculation module 20 as interface adjustment information, so as to provide a basis for determining the target display information and refreshing the electronic clock interface.

[0084] The address for reading the initial display information and the address for storing the target display information serve as the basis for the calculation module 20 to read the initial display information and store the target display information, thereby providing a data source for the calculation module 20 and enabling its data output. The image size of the electronic clock interface corresponds to the display width and height of the electronic clock interface, allowing the calculation module 20 to calculate the target display information according to the image size of the electronic clock interface. The interrupt instruction configuration parameters are used to generate interrupt instructions to notify the control module 10 of the completion of the target display information determination by the calculation module 20, thereby enabling subsequent scheduling and control.

[0085] In this embodiment, at least one of the following is used together with the rotation angle information: the reading address of the initial display information, the storage address of the target display information, the image size of the electronic clock interface, and the interrupt instruction configuration parameters. This provides a guarantee for the determination of the target display information and its subsequent use, which is beneficial to improving the efficiency and stability of the display control process.

[0086] In some embodiments, the interface adjustment information also includes interrupt instruction configuration parameters, referencing Figure 4 As shown, the display control method also includes: S410: In response to determining the target display information, the calculation module generates an interrupt command based on the interrupt command configuration parameters and sends it to the control module.

[0087] In step S410, after obtaining the target display information, the calculation module 20 can enable interruption according to the interrupt instruction configuration parameters in the interface adjustment information to generate an interrupt instruction, and send the interrupt instruction to the control module 10 to notify the control module 10 of the message that the calculation module 20 has completed the determination of the target display information.

[0088] S420. In response to the interrupt command, the control module generates a display command and display configuration parameters and sends them to the display processing module.

[0089] In step S420, when the control module 10 receives an interrupt command, it indicates that the calculation module 20 has completed the determination of the target display information. The display processing module 30 can then begin controlling the display screen to refresh the electronic clock interface according to the target display information. The control module 10 generates display commands and display configuration parameters and sends them to the display processing module 30. The display configuration parameters may include, for example, the storage address of the target display information, the transparency blending mode, and the position offset. This enables the display processing module 30 to read the target display information from its storage address upon receiving the display command and execute the refresh control process of the electronic clock interface according to the target display information and the display configuration parameters.

[0090] In this embodiment, when the interface adjustment information also includes interrupt command configuration parameters, the calculation module 20 generates an interrupt command based on the interrupt command configuration parameters and sends it to the control module 10 when determining the target display information. This notifies the control module 10 that the determination of the target display information has been completed. When the control module 10 receives the interrupt command, it generates a display command and display configuration parameters and sends them to the display processing module 30. This provides an indication and basis for the display processing module 30 to control the display screen to refresh the electronic clock interface, realizing the scheduling and control of the display processing module 30, which is beneficial to improving the efficiency and stability of the display control process.

[0091] In some embodiments, the initial display information includes the initial pixel information of each pixel of the electronic clock interface.

[0092] The initial display information of the electronic clock interface includes the initial pixel information of each pixel of the electronic clock interface at the time of the last refresh. The initial pixel information may include, for example, the position information of the pixel and the channel value of each channel.

[0093] refer to Figure 5 As shown, based on the interface adjustment information and the initial display information of the electronic clock interface, the target display information of the electronic clock interface is determined, including: S210. Divide each pixel of the electronic clock interface into a first pixel corresponding to the target pointer and a second pixel other than the first pixel.

[0094] In step S210, based on the initial pixel information, the pixels of the electronic clock interface are divided into first pixels and second pixels. The pixel corresponding to the target pointer is the first pixel, and all other pixels are the second pixels, such that the first pixel is the pixel at the location of the target pointer, and all first pixels together constitute the corresponding target pointer. For example, the calculation module 20 can read the initial pixel information pixel by pixel and filter the first pixels based on the pixel's channel value.

[0095] S220. Based on the initial pixel information and interface adjustment information of each first pixel, determine the target pixel information of each first pixel.

[0096] S230. Determine the target display information based on the target pixel information of each first pixel and the initial pixel information of each second pixel.

[0097] In steps S220 and S230, since refreshing the electronic clock interface only involves rotating the target pointer while other interface elements remain stationary, pixel adjustment only involves adjusting the first pixel. The target pixel information for each first pixel can be determined based on its initial pixel information and interface adjustment information, serving as the adjusted pixel information for each first pixel. Then, based on the target pixel information of each first pixel and the initial pixel information of the second pixel (i.e., the adjusted pixel information corresponding to the rotated target pointer) and the unadjusted pixel information corresponding to other stationary interface elements, the target display information is determined, providing a basis for refreshing the electronic clock interface.

[0098] In this embodiment, the pixels of the electronic clock interface are divided into first pixels corresponding to the target pointer and second pixels other than the first pixels. Based on the initial pixel information of each first pixel and interface adjustment information, the target pixel information of each first pixel is determined. Then, based on the target pixel information of each first pixel and the initial pixel information of each second pixel, the target display information is determined, providing a basis for refreshing the electronic clock interface. By selecting the first pixels related to the target pointer for calculating the target pixel information, the calculation of second pixels unrelated to the electronic clock interface can be directly skipped, significantly reducing the actual computational load of the calculation module 20. This is beneficial for further reducing power consumption and resource consumption during the display refresh process.

[0099] In some embodiments, the first pixel is configured as a pixel whose transparency channel value is greater than 0.

[0100] For each target pointer's corresponding pointer layer, the pixel corresponding to the target pointer needs to be displayed in the final electronic clock interface, while other pixels do not. Therefore, the alpha value of the pixel's transparency channel can be used as the basis for dividing the first and second pixels. Pixels with an alpha value greater than 0 (not fully transparent) are designated as the first pixel, and pixels with an alpha value of 0 (fully transparent) are designated as the second pixel. When determining the target display information, only the target pixel information of pixels with an alpha value greater than 0 can be calculated, while the initial pixel information of pixels with an alpha value of 0 can be retained.

[0101] In this embodiment, pixels with a transparency channel value greater than 0 are used as the first pixel, enabling the calculation module 20 to quickly and accurately divide the first pixel into the second pixel, further reducing the actual computational load of the calculation module 20, thereby reducing the power consumption and resource consumption of the display refresh process.

[0102] In some embodiments, the initial pixel information includes the initial position information of the pixel. Determining the target pixel information of each first pixel based on the initial pixel information and interface adjustment information includes: determining the target position information of each first pixel based on the initial position information and interface adjustment information, and using this as the target pixel information of each first pixel.

[0103] The initial pixel information corresponding to each pixel can include the initial position information of the pixel, such as the pixel's coordinates in the two-dimensional coordinate system corresponding to the display area. When determining the target pixel information of the first pixel, the target position information of each first pixel can be determined based on the initial position information and interface adjustment information, and used as the target pixel information of each first pixel, so that the rotation change of the target pointer can be reflected by the position change of the first pixel.

[0104] For example, the initial position information of the first pixel is the initial coordinates (x, y), and the rotation angle information included in the interface adjustment information is the trigonometric function values ​​sin(θ) and cos(θ) corresponding to the rotation angle. The target coordinates (x_new, y_new) of the first pixel after position adjustment can be determined as the target position information of the first pixel through the following formulas (3) and (4): x_new=x×cos(θ)- y×sin(θ) (3) y_new=x×sin(θ)+ y×cos(θ) (4) It should be noted that if the target coordinates are determined based on the magnified trigonometric function vertex values, the calculation results need to be scaled down according to the magnification factor of the trigonometric function vertex values ​​to ensure that the coordinate transformation process is an integer operation. For the final target coordinates, if the target coordinates are not integers, the rotational jagged edges can be eliminated by using the bilinear interpolation algorithm in calculation module 20.

[0105] In this embodiment, the initial position information of the pixel is used as the initial pixel information. Based on the initial position information of each first pixel and the interface adjustment information, the target position information of each first pixel is determined and used as the target pixel information of each first pixel. The rotation of the target pointer can be reflected by the position adjustment of the first pixel, so as to provide a basis for determining the target display information and refreshing the electronic clock interface. The calculation method is simple and has a small error, which improves the efficiency and accuracy of determining the target display information.

[0106] In some embodiments, the display control method further includes: in response to enabling the always-on display mode, the display processing module 30 controls the display screen to display an electronic clock interface.

[0107] When the Always-On Display (AOD) mode is detected, the display processing module 30 controls the display screen to show the electronic clock interface and executes the display control process shown in the above embodiments to achieve real-time refreshing of the electronic clock interface in AOD mode, continuously providing users with accurate time information. For example, as... Figure 1 As shown, when the always-on display mode is enabled, the application processing module 40 of the processor can wake up the control module 10, so that the control module 10 sends a display command to the display processing module 30, so that the display processing module 30 controls the display screen to display the electronic clock interface.

[0108] When the always-on display processing module 30 is exited, the control module 10 can control the calculation module 20 and the display processing module 30 to stop their current tasks, so as to release the resources of the calculation module 20 and the display processing module 30, so that the calculation module 20 and the display processing module 30 can be used to perform other tasks other than refreshing the display of the electronic clock interface.

[0109] In this embodiment, when the always-on display mode is detected, the display processing module 30 controls the display screen to display the electronic clock interface, so that the electronic clock interface can start displaying when the always-on display mode is activated and refresh in real time during the always-on display mode. Since the control module 10, the calculation module 20 and the display processing module 30 can reduce the power consumption and resource consumption of the display refresh process, which matches the requirements of the always-on display mode for low power consumption and low resource consumption, there is no need for high-power processors such as GPUs or APs to participate in the display control process during the always-on display mode.

[0110] In some embodiments, the control module 10 includes a microprocessor unit, the computing module 20 includes a visual digital signal processor, the display processing module 30 includes a display processing unit, and the processor includes a system-on-a-chip that integrates the microprocessor unit, the visual digital signal processor, and the display processing unit.

[0111] The microprocessor unit (MCU) features low power consumption, low cost, fast response, and flexible adaptability, meeting the performance requirements of the control module 10 when it only needs to handle scheduling and control. The MCU can be used as the control module 10 to determine interface adjustment information and send interface adjustment information and calculation instructions. The visual digital signal processor (VDSP) features low power consumption and single-instruction multiple-data parallel processing, enabling it to process pixel information from multiple pixels simultaneously. This meets the performance requirements of the computing module 20 when it only needs to handle data processing. The VDSP can be used as the computing module 20 to determine target display information. The display processing unit (DPU) features image generation capabilities and hardware acceleration, meeting the performance requirements of the display processing module 30 when it needs to handle image synthesis and display refresh control. The DPU can be used as the display processing module 30 to control the display screen to refresh the electronic clock interface.

[0112] The microprocessor unit, visual digital signal processor, and display processing unit can be integrated into a system-on-a-chip (SoC) to achieve the integration of the control module 10, computing module 20, and display processing module 30 within the processor. Through the collaboration of the microprocessor unit, visual digital signal processor, and display processing unit, the display control process of the electronic clock interface is decomposed into stages of scheduling control, data processing, and display refresh control, so as to fully utilize the characteristics of the microprocessor unit, visual digital signal processor, and display processing unit to optimize the display control process.

[0113] In this embodiment, the microprocessor unit, the visual digital signal processor, and the display processing unit are respectively designated as the control module 10, the computing module 20, and the display processing module 30, and are integrated into a system-on-a-chip. This provides hardware support for the execution of the display control process, and can utilize the characteristics of the three components to achieve single responsibility and standardized interfaces, as well as optimization of power consumption and resource utilization. It can simultaneously meet the requirements for smoothness and diversity of display effects and battery life, thereby improving the user experience.

The interface adjustment information includes the rotation angle information of the target pointer of the electronic clock interface. The calculation module 20 is used to determine the target display information of the electronic clock interface based on the interface adjustment information and the initial display information of the electronic clock interface in response to the calculation instructions. The display processing module 30 is used to control the display screen to refresh the electronic clock interface based on the target display information.

[0115] In this embodiment, the control module 10 determines the interface adjustment information and sends the interface adjustment information and calculation instructions to the calculation module 20. Upon receiving the calculation instructions, the calculation module 20 determines the target display information based on the interface adjustment information and the initial display information. Then, the display processing module 30 controls the display screen to refresh the electronic clock interface based on the target display information, thus achieving display refresh control of the electronic clock interface. This ensures that the electronic clock interface continuously provides accurate time information to the user, meeting the user's time viewing needs. By setting the control module 10, calculation module 20, and display processing module 30 in the processor, each serving as an independent module with a single responsibility for scheduling control, data processing, and display refresh control, it ensures that each module can achieve display control of the electronic clock interface with simple algorithms and hardware deployment.
