[0001] This application relates to the field of screen display technology, and in particular to a screen display control method, apparatus, device and medium. Background Technology

[0002] Many portable devices nowadays have screens, and their display technologies are mostly designed for standard rectangular screens. Their data transmission typically uses a local rectangular block method to transmit image data. For non-rectangular screens (such as circular, elliptical, or irregular polygonal screens), the device's main control chip transmits image data to the screen regardless of whether the image data will be displayed on the screen. This results in a large number of invalid pixels being transmitted, wasting bandwidth resources. Summary of the Invention

[0022] The screen is divided into multiple non-intersecting rectangular regions in a top-to-bottom order; wherein the total area covered by the multiple non-intersecting rectangular regions is larger than the screen area and smaller than the screen's outer rectangular region.

[0041] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0042] This application provides a screen display control method, apparatus, device, and medium to reduce the amount of image data that needs to be transmitted to a non-rectangular screen for refresh display, thereby saving transmission bandwidth and enabling non-rectangular screen products to support higher resolutions and color bit depths.

[0043] The methods, apparatus, equipment, and media are based on the same concept of the application. Since the methods, apparatus, equipment, and media solve problems in similar principles, the implementation of the apparatus, equipment, media, and methods can refer to each other, and repeated parts will not be described again.

[0044] The terms "first," "second," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0045] The following examples and embodiments are to be understood as illustrative only. While this specification may refer to "a," "an," or "some" examples or embodiments in several places, this does not mean that every such reference relates to the same example or embodiment, nor does it mean that the feature applies only to a single example or embodiment. Individual features of different embodiments may also be combined to provide other embodiments. Furthermore, terms such as "comprising" and "including" should be understood not to limit the described embodiments to consisting only of those features mentioned; such examples and embodiments may also include features, structures, units, modules, etc., not specifically mentioned.

[0046] The various embodiments of this application will now be described in detail with reference to the accompanying drawings. It should be noted that the order in which the embodiments are presented in this application represents only a chronological order and does not represent the superiority or inferiority of the technical solutions provided by the embodiments.

[0047] Portable devices that prioritize low cost and low power consumption often use simple display interfaces, such as SPI (Serial Peripheral Interface), QSPI (Quad Serial Peripheral Interface), or MCU (Microcontroller Unit) interfaces. In addition, the clock frequency of these interfaces is limited (for example, the typical value of SPI interface is 50MHz), so the interface transmission bandwidth is greatly limited, making it difficult for products to support screens with high resolution and high color bit depth.

[0048] In this embodiment of the application, for screens that commonly support local area refresh, the non-rectangular screen area is refreshed and displayed to optimize the transmission bandwidth. By saving transmission bandwidth, higher resolution and color bit depth can be supported.

[0049] See Figure 1 This application provides a screen display control method, including:

[0050] S101. Obtain the area currently requested to be refreshed for screen display; wherein, the area is used by the terminal application to refresh the displayed image; the screen is a non-rectangular screen of the terminal;

[0051] The terminal may be, for example, a portable device with a non-rectangular screen, such as a circular screen.

[0052] The application refers to the software module that sends display requests to the main control chip's display controller, such as a GUI (Graphics User Interface).

[0053] It should be noted that the screen display control method provided in this application embodiment is mainly applied to the display control of non-rectangular screens, which can achieve the effect of saving transmission bandwidth. Of course, the screen display control method provided in this application embodiment can also be applied to the display control of rectangular screens.

[0054] The area currently requesting a screen refresh can be a local area of ​​the screen, and the shape of the local area can be a rectangular area.

[0055] S102. Using the area currently requested to refresh the screen display, and multiple preset rectangular areas obtained by dividing the screen according to preset rules, determine multiple target rectangular areas that need to be refreshed for the current screen display; wherein, the total target area composed of the multiple target rectangular areas is smaller than the area currently requested to refresh the screen display.

[0056] In some implementations, the screen is divided into multiple preset rectangular regions according to preset rules, including:

[0057] The screen is divided into multiple non-intersecting rectangular regions in a top-to-bottom order; wherein the total area covered by the multiple non-intersecting rectangular regions is larger than the screen area and smaller than the screen's outer rectangular region.

[0058] For example Figure 2As shown, the circular screen is divided into three non-intersecting rectangular regions, namely region 1, region 2, and region 3, in order from top to bottom. The total area covered by these three regions is larger than the circular screen area but smaller than the outer rectangular area of ​​the circular screen.

[0059] In some implementations, multiple target rectangular regions are determined using the area currently requesting a screen display refresh, and multiple rectangular regions obtained by dividing the screen according to preset rules, including:

[0060] Determine the intersection area of ​​the area currently requested to be refreshed for screen display with each of the multiple preset rectangular areas to obtain multiple target rectangular areas;

[0061] The plurality of preset rectangular regions are multiple rectangular regions obtained by dividing the screen according to preset rules.

[0062] For example, the user selects the area currently requesting a screen refresh via the GUI. Figure 2 Given the rectangular local area on the left side of the circular screen shown, we can find the intersection of this local area with areas 1, 2, and 3 respectively, and determine each intersection area to obtain three target rectangular areas, which are the areas that need to be refreshed and displayed.

[0063] S103. Based on the multiple target rectangular regions, control the screen to refresh and display images.

[0064] In some implementations, controlling the screen refresh to display the image based on the plurality of target rectangular regions includes:

[0065] Determine the area refresh list, which includes screen display refresh information for each of the target rectangular areas;

[0066] The screen refresh display image is controlled by the area refresh list.

[0067] The screen display refresh information for each target rectangular area refers to various information used to refresh the image display for that target rectangular area on the screen, such as related commands, area location, pixel address, and so on.

[0068] The area refresh list is a list that includes the screen display refresh information for each target rectangular area. Of course, it may also include other information, such as refresh delay information between target rectangular areas, etc.

[0069] In some implementations, the screen display refresh information includes image display position information and image address information;

[0070] The specified area refresh list includes:

[0071] For each target rectangular region, determine the image display position information and image address information for that target rectangular region;

[0072] Based on the image display location information and image address information of each target rectangular region, a region refresh list is generated.

[0073] Specifically, for each target rectangular region, the image display position information for that region includes, for example, the coordinates of the top-left and bottom-right vertices (e.g., using the top-left corner of the outer rectangle of the circular screen as the origin). The image address information for that target rectangular region refers to the storage address information of the image displayed within that region in memory, such as the image start address. Subsequently, the display controller can read the corresponding image data from memory based on the image address information of the target rectangular region, and output the read image data to be displayed within the target rectangular region based on the image display position information of that region.

[0074] In some implementations, the screen display refresh information also includes: a command to set area coordinates and a command to start transmission.

[0075] The commands for setting area coordinates include, for example, the CASET (Set Column Start Address) range command and the RASET (Set Row Start Address) range command.

[0076] The start transmission command, for example: RAMWR (Memory Start Write, indicating the start of transmission of image pixels within the range set by CASET and RASET) command.

[0077] In some implementations, the area refresh list further includes: screen refresh delay duration information between adjacent areas.

[0078] The screen refresh delay information between adjacent areas indicates that there needs to be a certain time interval between two local area refreshes of the screen (if not required, this information can be 0).

[0079] The following is an example of a specific embodiment.

[0080] Assuming the screen is Figure 2 Given the circular screen shown, the screen display refresh control method included in this embodiment includes:

[0081] Step 1: Refresh the actual physical display area on the screen (e.g., only the inner part of a circular screen needs to be refreshed, or for a certain period of time, only a non-rectangular area needs to be refreshed). Figure 2 As shown, the screen is divided vertically into multiple rectangular regions from top to bottom, forming a list of regions on the screen (including region 1 to region 3).

[0082] It should be noted that the area can also be divided horizontally from left to right. In other words, the embodiments of this application are also applicable to horizontal area division. However, considering that the existing physical screen scanning methods are basically from top to bottom, it is better to divide the area vertically than horizontally. If the screen scanning direction is from left to right, then it is better to divide the area horizontally from left to right.

[0083] These rectangular regions do not intersect, and their union can cover the entire visible physical display area of ​​the screen, for example... Figure 2 The circular screen shown is divided into three regions labeled 1, 2, and 3. In some embodiments, the more regions there are, the more bandwidth can be saved. For example, Figure 3 As shown, the area is divided into 5 regions, namely region 0 to region 4, but the combined area of ​​these 5 regions is less than... Figure 2 The total area of ​​the three regions shown is small, so the total number of image pixels that need to be transmitted is smaller. For this circular screen, theoretically, the maximum saving in transmission bandwidth is 21%.

[0084] Step 2, for example Figure 4 As shown, the rectangular area requested for refresh by the application is... Figure 4 The area 4 shown has a top-left corner (g) and a bottom-right corner (h). It intersects with the rectangular areas in the screen area list from step one to form the actual refresh area list, including rectangular area 5 (top-left corner i and bottom-right corner j), rectangular area 6 (top-left corner k and bottom-right corner m), and rectangular area 7 (top-left corner e and bottom-right corner h).

[0085] It should be noted that the point at the lower right corner of the rectangular area described in this application embodiment belongs to the last pixel at the lower right corner of that area. For example, point h at the lower right corner of area 4 is the last pixel at the lower right corner inside area 4 (the same applies to other areas).

[0086] The application refers to the software module that sends display requests to the main control chip's display controller, such as a GUI (Graphics User Interface).

[0087] In some embodiments, by calculating the image start address offset through coordinate offset, the starting (memory) address of the image to be transmitted can be obtained for the list of regions that actually need to be refreshed (i.e., the actual refresh region list including rectangular regions 5 to 7 mentioned above).

[0088] For example, suppose the display request sent by the application includes the following information:

[0089] Information about rectangle 4 includes the coordinates (Xg, Yg) of the top left vertex g and the coordinates (Xh, Yh) of the bottom right vertex h;

[0090] Image starting address ADDR;

[0091] Image stride, which is the number of bytes in a row or the address offset of an adjacent row;

[0092] Image format, i.e., the number of bytes per pixel, is denoted as bytes_per_pixel (abbreviated as bpp).

[0093] Therefore, based on the information included in the display request sent by the above application, the area coordinates and image starting address of areas 5, 6, and 7 can be calculated:

[0094] For example Figure 4 As shown, the origin O is located at the top left corner vertex of the bounding rectangle of the display screen. Therefore, regarding region 5:

[0095] The coordinates of the top-left vertex i of region 5 are (Xi,Yi)=(MAX(Xa,Xg),MAX(Ya,Yg));

[0096] The coordinates of the lower right vertex j of region 5 are (Xj,Yj)=(MIN(Xb,Xh),MIN(Yb,Yh));

[0097] Since point j in the bottom right corner of region 5 is the last pixel in the bottom right corner inside region 5, therefore:

[0098] The width of region 5 is width(5) = Xj - Xi + 1;

[0099] The height of region 5 is (5) = Yj - Yi + 1;

[0100] If either the width or height of region 5 is less than 1, it means that rectangular region 4 does not intersect with region 1 and does not need to be added to the refresh region list.

[0101] The starting address of the image in region 5 is:

[0102] ADDR(5)=ADDR+(Yi-Yg)*stride+(Xi-Xg)*bytes_per_pixel (ie bpp).

[0103] Thus, refreshing the entire region 4 defined by vertices g and h becomes refreshing regions 5, 6, and 7. The total area of ​​regions 5, 6, and 7 is smaller than the original area of ​​region 4, thereby reducing the image data transmission bandwidth. In other words, this embodiment reduces the amount of image refresh data transmitted from the main control chip to the display screen, thereby reducing the transmission bandwidth.

[0104] Step 3: Refresh the image data of the refresh area list obtained in Step 2, namely Area 5, Area 6, and Area 7, to the screen. In other words, through multiple local (rectangular area) refreshes of the screen, the effective visible image content is updated to the screen.

[0105] In some embodiments, partial screen refresh requires first updating the refresh area position via a command, then sending another command to instruct the transmission of image data, and finally transmitting the image data.

[0106] For example Figure 5 As shown, one method involves the CPU in the main control chip sending the screen display refresh information of areas 5, 6, and 7 to the display controller in the main control chip one by one, and then the display controller refreshes the corresponding image data to the screen. It can be seen that this method requires the main control chip to participate in the data transmission process multiple times.

[0107] in, Figure 5 The “delay” shown indicates that there needs to be a certain time interval between two local area refreshes of the screen (the specific delay can be determined according to actual needs; if no delay is needed, the delay is 0).

[0108] To further improve screen refresh efficiency, in some embodiments, this area information can be organized into a region refresh list (including refresh region commands and corresponding image transmission addresses) by the main control chip's display controller according to screen interface commands and protocols. For example... Figure 6 As shown, the display controller reads information from the list to refresh the image in each area. The information for each area includes, for example... Figure 7 As shown. Depending on the screen interface used in the actual application, such as the QSPI interface, the list information for any region (region 5, region 6, region 7) can be, for example... Figure 8 As shown; for MCU or SPI interfaces, the list information for any region (region 5, region 6, region 7) can be, for example... Figure 9As shown. The 24-bit reserved bits are to facilitate the display controller reading information from the list. For example, the display controller can still... Figure 8 The 32-bit representation reads the CASET command, but only the first 8 bits are valid; the remaining 24 bits are empty. Of course, this is an optional method; different methods can be set for the display controller to read list information for different interfaces.

[0109] exist Figure 8 and Figure 9 middle:

[0110] CASET is Set Column Start Address, which sets the column address range (i.e., sets the x-range range). The parameters are the x-coordinates of the top-left and bottom-right corners of the rectangular area.

[0111] RASET stands for Set Row Start Address, which sets the row address range (i.e., sets the y-range range). The parameters are the y-coordinates of the top-left and bottom-right corners of the rectangular area.

[0112] RAMWR stands for Memory Start Write, indicating the start of transferring image pixels in the area defined by CASET and RASET, with no parameters.

[0113] Image address, region width, region height. After transmitting the above three commands (CASET, RASET, RAMWR), the main control chip reads image pixels from the image address. It reads width pixels for each line, and then offsets the image address by the line address offset stride (as shown in step two, stride is passed in when the application requests a refresh, and it is the same for each target rectangular region (region 5, region 6, region 7), so it does not need to be included in each item), and reads the next line until the height number of lines has been read.

[0114] In summary, for non-rectangular screens (or screen areas that actually need to be refreshed being non-rectangular), this application embodiment can divide the screen into multiple target rectangular regions, thereby saving transmission bandwidth. This allows the product to support higher screen resolutions or higher color bit depths even with limited bandwidth. Furthermore, the multiple local refresh regions (i.e., the aforementioned multiple target rectangular regions) formed in this application embodiment, after being organized into a region refresh list, are directly read by the main display controller, automatically completing the data transmission across multiple regions without software intervention, resulting in higher screen refresh efficiency.
