[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Figure 1 The diagram shown is a flowchart illustrating a screen display method provided in an embodiment of this application. Figure 1 As shown, the method includes the following steps.

[0027] Step S110: Divide the target display screen to obtain multiple display areas in the target display screen.

[0028] Specifically, the target display screen is divided into multiple smaller display areas. This division allows for independent processing of each display area, rather than applying a uniform processing rule to the entire target display screen's current image. For example, the target display screen can be divided into reasonable areas based on screen hardware characteristics, such as screen resolution, screen size, and the refresh rate range supported by the hardware. Alternatively, the target display screen can be divided based on the type of content displayed on the screen, such as text, images, or videos.

[0029] Step S120: Determine whether the current image of each of the multiple display areas has changed.

[0030] Specifically, two consecutive images of the same display area are compared to determine whether the current image of that display area has changed.

[0031] In one example, image data is extracted from two consecutive images of the same display area. This image data refers to pixel information extracted at a specific moment, specifically including pixel values, color space, texture information, brightness and contrast, spatial location, timestamp, feature descriptions, etc. Pixel values ​​are the most basic form of image data, representing the color and brightness information of each point in the image; color spaces include RGB (red, green, blue) and HSV (hue, saturation, brightness); texture information describes the repeating patterns or structures of regions in the image; spatial location is the position of each pixel in the image (represented by rows and columns); the timestamp indicates the specific time the image was captured; feature descriptions include edges, corners, scale-invariant feature transform (SIFT) or directional fast feature detection, and rotationally robust unique descriptors (ORB).

[0032] Furthermore, change detection algorithms can be used to compare image data of two consecutive images within the same display area. For example, change detection algorithms include pixel-level comparison, threshold comparison, and feature matching. Pixel-level comparison directly compares the pixel value differences between two consecutive images; threshold comparison sets a threshold, and only when the pixel value difference exceeds this threshold is a change considered to have occurred; feature matching extracts key points and descriptors, and identifies changes between two consecutive images by matching these features. For instance, after obtaining the difference between two consecutive images, if the difference exceeds the threshold, the current image in the display area is considered to have changed. Then, the change detection result is output, which includes information such as the position and size of the corresponding display area and the degree of change in the current display image.

[0033] Step S130: Determine the refresh rate of the display area based on the changes in the current image of each display area.

[0034] Refresh rate refers to the number of times a display screen updates its image per unit of time, usually expressed in Hertz (Hz). Changes in the current image can be categorized into two scenarios: the current image changes, and the current image remains unchanged.

[0035] For example, in a real-world scenario, if it is determined that the current image in the display area has not changed, the refresh rate of that display area can be reduced. For instance, if the base refresh rate of the display area is 120Hz, the refresh rate can be reduced to 60Hz or lower for display areas where the image has not changed. If it is determined that the current image has changed, the original refresh rate of the display area can be maintained.

[0036] Furthermore, it should be noted that the refresh rate adjustment is dynamic. That is, between consecutive image frames, whenever a change in the image frame of the displayed area is detected, the refresh rate of that area may be readjusted. When adjusting the refresh rate, a smooth transition technique can be used to avoid display flickering or other visual artifacts caused by sudden refresh rate changes.

[0037] This embodiment allows for dynamic adjustment of the refresh rate for different areas of the screen based on content changes. This means that while maintaining a smooth visual experience, a lower refresh rate can be used for static content, while dynamic content is refreshed at the original refresh rate, achieving an optimal balance between display quality and power consumption. Specifically, it detects whether the image in each display area has changed. If a change has occurred, the refresh rate remains unchanged, while for areas where the image has not changed, the refresh rate is reduced, thereby reducing power consumption, extending the screen's battery life, and slowing down the screen aging process.

[0038] Figure 2 The diagram shown is a flowchart illustrating the process of determining the refresh rate of a display area according to an embodiment of this application. Figure 1 Extending from the illustrated embodiment Figure 2 The illustrated embodiment will be described in detail below. Figure 2 The illustrated embodiments and Figure 1 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0039] like Figure 2 As shown, the refresh rate of the display area is determined based on the changes in the current image frame of each display area, including:

[0040] Step S210: If the current image of the display area changes, the refresh indicator corresponding to the current image of the display area is set to zero.

[0041] A refresh indicator of zero means that there is an internal counter or indicator that tracks the refresh status of the display area. If the current image in the display area changes, the value of the counter for that area is set to zero, indicating that the display area needs to be refreshed at the base refresh rate.

[0042] Step S220: Refresh the current image in the display area where the refresh indicator is zero at the base refresh rate.

[0043] The base refresh rate refers to the number of times per second that the target display screen refreshes its displayed content under normal operating conditions. The unit of refresh rate is Hertz (Hz), for example, a 120Hz refresh rate means that the screen refreshes 120 times per second.

[0044] In this embodiment, when the refresh indicator value is zero, it means that the display area needs to refresh the current image once according to the base refresh rate to ensure that the displayed content is up-to-date, or to maintain the continuity and stability of the displayed content.

[0045] In this embodiment, for display areas where the image changes, refreshing at the base refresh rate ensures that the image within the display area is always up-to-date, thus providing a clearer and smoother display effect. Secondly, the method of refreshing when the refresh indicator is zero, along with refreshing the current image of the display area when there is no change, and refreshing the current image of the display area when the remainder of the number of times the current image of the display area remains unchanged divided by the refresh rate adjustment factor is zero, thus adjusting the refresh rate of the display area, logically forms a closed loop. That is, by using the zero marker, both refreshing the display area at the base refresh rate when changes occur, and adjusting the refresh rate of the display area when there are no changes, are achieved.

[0046] Combination Figure 1 In the embodiments shown, in other embodiments of this application, the target display screen is divided to obtain multiple display areas in the target display screen, including: dividing the target display screen based on a pixel size of w*h to obtain multiple display areas with a pixel size of w*h.

[0047] Specifically, 1 ≤ w ≤ W, 1 ≤ h ≤ H, where W and H are the width and length of the target display screen, respectively. Using this partitioning method, the screen is divided into several small regions with the same pixel size, and the set of these small regions covers the entire screen. Furthermore, there is no overlap between the resulting small regions; that is, their pixels are not shared, and each pixel belongs to only one specific small region.

[0048] Figure 3 The diagram shown is a schematic representation of dividing a target display screen according to an embodiment of this application. Figure 3 As shown, the pixel size of each display area is the same, and there is no overlap between the display areas.

[0049] In this embodiment, display areas of the same size facilitate unified management and scheduling, simplifying the design and implementation of screen display control algorithms, allocating screen resources more fairly, and avoiding uneven display caused by differences in the size of certain areas. Simultaneously, it ensures uniform refresh rate and improves refresh performance when the current image in a display area changes. Furthermore, non-overlapping display areas allow for precise control of each area, including brightness adjustment, color management, and refresh rate settings, without affecting other areas. This ensures that the displayed content is visually clear and distinct, avoiding visual confusion or interference that may be caused by overlapping areas.

[0050] Figure 4 The diagram shown is a flowchart illustrating the process of determining the refresh rate of a display area according to an embodiment of this application. Figure 1 Extending from the illustrated embodiment Figure 4 The illustrated embodiment will be described in detail below. Figure 4 The illustrated embodiments and Figure 1 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0051] like Figure 4 As shown, in this embodiment, the refresh rate of the display area is determined based on the changes in the current image of each display area, including the following steps.

[0052] Step S410: Record the number of times the current image in the display area remains unchanged when the current image in the display area does not change.

[0053] Specifically, a counter is set up for the number of times the image in each display area remains unchanged, with an initial value of 0. During image display, the image in each display area is continuously monitored. Whenever it is detected that the current image in the display area is the same as a historical image, i.e., no change has occurred, the counter is incremented by 1. If a change occurs, the counter value is set to 0, and the counting restarts.

[0054] For example, suppose there is a display area with a base refresh rate of 120Hz. At time t1, the current image of the display area is the same as the historical image, and the counter increments by 1, so the counter value is 1. At time t2, the current image of the display area is also the same as the historical image, and the counter increments by 1, so the counter value is 2. At time t3, the current image of the display area is also the same as the historical image, and the counter increments by 1, so the counter value is 3. At time t4, the current image of the display area is different from the historical image, and the counter resets to 0. At time t5, the current image of the display area is the same as the historical image, and the counter increments by 1, so the counter value is 1. At time t6, the current image of the display area is the same as the historical image, and the counter increments by 1, so the counter value is 2.

[0055] Step S420: Determine the refresh rate of each of the multiple display areas based on the number of times the current image in the display area remains unchanged.

[0056] In this step, the refresh rate is adjusted based on the number of times no change is recorded in step S410.

[0057] For example, a threshold can be set, and when the number of times the image remains unchanged reaches this threshold, the refresh rate of the display area can be automatically reduced. Conversely, if the image in the display area changes frequently, the refresh rate can be increased to maintain image smoothness and responsiveness. For example, a threshold of 3 means that when the image remains unchanged for at least 3 consecutive times, the refresh rate of the display area can be reduced, for example, from 120Hz to 60Hz.

[0058] In this embodiment, the refresh rate is optimized based on the actual changes in the displayed content to improve overall display efficiency. Specifically, by reducing the refresh rate of display areas that have not changed for a long time, unnecessary power consumption and visual interference can be reduced. This method can adapt to different display content and usage scenarios, providing more flexible display management.

[0059] Figure 5 The diagram shown is a flowchart illustrating the process of determining the refresh rate of multiple display areas according to an embodiment of this application. Figure 4 Extending from the illustrated embodiment Figure 5 The illustrated embodiment will be described in detail below. Figure 5 The illustrated embodiments and Figure 4 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0060] like Figure 5 As shown, in this embodiment, the refresh rate of each of the multiple display areas is determined based on the number of times the current image of the display area remains unchanged, including the following steps.

[0061] Step S510: Determine the refresh rate adjustment factor.

[0062] The refresh rate adjustment factor is used to calculate when to refresh the image in the display area. This adjustment factor can be a fixed value or a value dynamically calculated based on certain conditions (such as the type of content displayed, user interaction, energy efficiency optimization goals, etc.).

[0063] Step S520: If the remainder of the number of times the current image of the display area remains unchanged divided by the refresh rate adjustment factor is zero, then the current image of the display area is refreshed.

[0064] In other words, the decision to refresh the image is based on the number of times the image remains unchanged and the calculation result of the refresh rate adjustment factor.

[0065] Step S530: If the remainder of the number of times the current image of the display area remains unchanged divided by the refresh rate adjustment factor is not zero, then the current image of the display area will not be refreshed.

[0066] In other words, if the remainder when the number of unchanged events is divided by the refresh rate adjustment factor is not zero, then the refresh will be skipped, thereby reducing unnecessary refreshes and lowering energy consumption.

[0067] In some embodiments, the refresh indicator is R, where R = N%K. Here, % represents the remainder when N is divided by K, N represents the number of times the current image in the display area remains unchanged, and K represents the refresh rate adjustment factor. If the value of the refresh indicator R is zero, the current image in the display area is refreshed; if the value of the refresh indicator R is not zero, the current image in the display area is not refreshed.

[0068] Step S540: Determine the refresh rate of the display area based on the number of refreshes and non-refreshes within the target time period.

[0069] Specifically, the number of times the screen refreshed and did not refresh within the target time period is counted. Based on this statistical data, the average refresh rate can be calculated, and the refresh rate of the display area can be adjusted accordingly.

[0070] For example, assume the refresh rate adjustment factor is 5 and the base refresh rate is 120 times / second. If at a certain time point, the cumulative number of times the current image in a certain display area remains unchanged is 20 (20 is a multiple of 5, i.e., the remainder when 20 is divided by 5 is 0), then according to step S520, the display area can be refreshed. If at the next time point, the cumulative number of times the current image in that display area remains unchanged is 21 (the remainder when 21 is divided by 5 is not 0), then according to step S530, we do not refresh the display area.

[0071] Assuming the target time is 1 second, the number of times the image remains unchanged within this second is recorded 120 times. Since the refresh rate adjustment factor is 5, 24 of these 120 times (120 divided by 5) have a remainder of 0, meaning there will be 24 refreshes within this second. The remaining 96 times do not meet the refresh condition and therefore do not refresh. In this example, the refresh rate is 24 times / 1 second.

[0072] In this embodiment, by intelligently determining when to refresh the display area, unnecessary screen refresh operations can be significantly reduced, thereby lowering energy consumption. This method allows the display system to dynamically adjust the refresh rate based on changes in the current image, rather than operating at a fixed maximum refresh rate, thus adapting to different display content and usage scenarios.

[0073] Figure 6 The diagram shown is a flowchart illustrating the process of determining the refresh rate adjustment factor according to an embodiment of this application. Figure 5 Extending from the illustrated embodiment Figure 6 The illustrated embodiment will be described in detail below. Figure 6 The illustrated embodiments and Figure 5 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0074] like Figure 6 As shown, in this embodiment, determining the refresh rate adjustment factor includes the following steps.

[0075] Step S610: Determine the counting interval corresponding to the number of times the current image in the display area remains unchanged.

[0076] For example, multiple counting intervals are defined as (0, N1], (N1, N2], ..., (N... i-1 N i ]wait.

[0077] Step S620: Determine the refresh rate adjustment factor based on the count interval corresponding to the number of times the current image in the display area remains unchanged.

[0078] In some embodiments, Among them, K1 <K2<…<K i That is, as the counting interval (N) increases... i-1 N i As K increases i It is also increasing.

[0079] In other words, the larger the maximum value of the counting interval, the larger the refresh rate adjustment factor; the smaller the maximum value of the counting interval, the smaller the refresh rate adjustment factor. It's understandable that a larger counting interval means the image hasn't changed for a long time, so frequent refreshes aren't needed, resulting in a larger refresh rate adjustment factor; conversely, a smaller counting interval requires more frequent refreshes, leading to a smaller refresh rate adjustment factor.

[0080] Based on the description in the foregoing embodiments, the refresh indicator

[0081] Assume K1 = 2 and K2 = 3. From this formula, we know that when R equals 0, the current display area is refreshed. 2 represents the refresh rate adjustment factor within the interval (0, N1], and 3 represents the refresh rate adjustment factor within the interval (N1, N2]. If the value of N%2 is zero, then the current image in the display area corresponding to N is refreshed.

[0082] In this embodiment, the refresh rate adjustment factor increases with the upper limit of the counting interval. This method can adaptively adjust the refresh rate to respond to changes in the displayed content. When the image remains unchanged for a long time, the counting interval is large, and the corresponding refresh rate adjustment factor is also large, thereby reducing the refresh frequency, reducing unnecessary power consumption and unnecessary screen refreshes, thus alleviating the burden on the display hardware and improving the overall system performance. In addition, by avoiding unnecessary refreshes, screen flicker and image tearing can be reduced, providing a smoother and more comfortable visual experience. Furthermore, reducing the screen refresh rate can reduce physical wear and tear on the display device and extend its lifespan.

[0083] Figure 7 The diagram shown is a flowchart illustrating a process for determining whether the current image in a display area has changed, according to an embodiment of this application. Figure 1 Extending from the illustrated embodiment Figure 7 The illustrated embodiment will be described in detail below. Figure 7 The illustrated embodiments and Figure 1 The differences between the embodiments shown are not repeated here, and the similarities are not repeated here.

[0084] like Figure 7 As shown, in this embodiment, determining whether the current image of each of the multiple display areas has changed includes the following steps.

[0085] Step S710: Obtain the image data of the current image frame for each display area.

[0086] Step S720: Obtain the image data of the historical image corresponding to the current image of each display area.

[0087] Specifically, the historical image is the previous frame of the image corresponding to the current image.

[0088] In one example, the image data of the current image in the same display area can be directly compared with the image data of its corresponding historical image.

[0089] In another example, based on a Secure Hash Algorithm (SHA) and / or Cyclic Redundancy Check (CRC), a checksum corresponding to the image data of the current image frame in the display area is calculated, and the checksums corresponding to the image data of historical image frames in the same display area are obtained. The checksums of the current image frame and the historical image frames are then compared. This method ensures the accuracy of image data comparison, quickly determines whether the image has changed, and improves processing efficiency.

[0090] For example, checksums also include check codes. A checksum is a simple error detection code generated by adding (and sometimes inverting) certain bits of data, and can be used to detect errors in data transmission. CRC is a division-based checksum algorithm that uses polynomial division to generate a fixed-length binary sequence. CRC is more powerful than a simple checksum, capable of detecting more error types, and has a lower probability of collisions. SHA is a cryptographically secure hash function that can convert input of arbitrary length (such as text or image data) into a fixed-length output (hash value).

[0091] Step S730: If the image data of the current image frame is different from the image data of the historical image frames, then it is determined that the current image frame of each display area has changed.

[0092] Alternatively, if the checksum of the current image data is different from the checksum of the historical image data, then it is determined that the current image of the display area has changed.

[0093] The solution presented in this embodiment can monitor image changes in the display area in real time, reducing the need for manual monitoring, improving efficiency, and lowering labor costs. Compared to complex image processing algorithms, simple image data comparison reduces the consumption of computing resources, making the solution more efficient. Furthermore, this technology is easy to integrate into existing systems.

[0094] Furthermore, in this embodiment, a checksum is calculated using a secure hash algorithm and / or cyclic redundancy check (CRC), and the checksum is used to verify whether the image data in the displayed area has changed. Since the checksum is typically much shorter than the original image data, using a checksum can significantly reduce storage requirements. Secondly, in continuous video streams or image sequences, the image data of the current image frame and historical image frames may have a high degree of similarity; using a checksum can avoid storing a large amount of redundant image data. Additionally, calculating the checksum is faster than loading and processing the entire image file, which can improve the efficiency of detecting changes in image data.
