[0053] Figure 1 is a block diagram of the hardware configuration of an electronic device for implementing an FSD screen display method according to an embodiment of the present invention.

[0054] Electronic device 1000 can be a terminal or a server. Furthermore, the terminal can be a head-mounted device (such as an AR device, MR device, XR device, and VR device), a portable computer, a tablet computer, a PDA, etc. The server can be a cloud server, etc.

[0055] Electronic device 1000 may include processor 1100, memory 1200, interface device 1300, communication device 1400, display device 1500, input device 1600, speaker 1700, microphone 1800, etc. The processor 1100 may be an application processor (AP), which may include a CPU, GPU, DPU, MCU, etc. The memory 1200 may include, for example, ROM (Read-Only Memory), RAM (Random Access Memory), or non-volatile memory such as a hard disk. The interface device 1300 may include, for example, a USB interface, a headphone jack, etc. The communication device 1400 may be capable of wired or wireless communication. The display device 1500 may be, for example, an FSD type LCD screen, a touch screen, etc. The input device 1600 may include, for example, a touch screen, a keyboard, etc. Users can input / output voice information through the speaker 1700 and microphone 1800.

[0056] Although multiple devices are shown for electronic device 1000 in FIG1, the present invention may refer to only some of the devices therein. For example, electronic device 1000 may refer to only memory 1200 and processor 1100.

[0057] In an embodiment of the present invention, the memory 1200 of the electronic device 1000 is used to store instructions for controlling the processor 1100 to execute the FSD screen display method provided in the embodiment of the present invention.

[0058] In the above description, those skilled in the art can design instructions based on the scheme disclosed in this invention. How the instructions control the processor to operate is well known in the art, and therefore will not be described in detail here.

[0059] The display principle of FSD screen is: using time sequence to display sub-pictures such as red (R), green (G), and blue (B), and through the persistence of vision of the human eye, a full-color image is presented on the retina through the method of time color mixing.

[0060] This invention provides a display method for an FSD screen, which is applied to a processor in an electronic device as shown in Figure 1. The processor is specifically an application processor (AP). The AP typically includes a GPU, CPU, DPU, etc., and the FSD screen display method provided in this invention can be executed by at least one of the GPU, CPU, DPU, etc., in the AP.

[0061] As shown in Figure 2, the display method of the FSD screen provided by the present invention includes the following steps S2100 to S2400.

[0062] Step S2100: Obtain the first image in RGB format drawn by the application according to the physical screen size.

[0063] The physical screen size in step S2100 above refers to the actual screen size of the FSD screen. Based on the display principle of the FSD screen, each pixel occupies 1 byte. In one example, with a physical screen size of a*b, the width of the image displayed on the FSD screen is a pixels, which is also a bytes, and the height of the image displayed on the FSD screen is b pixels, which is also b bytes.

[0064] However, when drawing an image, the application first obtains the physical screen size of the FSD screen and then draws an RGB format image that conforms to the physical screen size of the FSD screen. In this embodiment, the RGB format image drawn by the application that conforms to the physical screen size of the FSD screen is denoted as the first image. Taking the physical screen size of the FSD screen as a*b as an example, the width of the RGB format image drawn by the application is a pixels, which is also 3a bytes, and the height is b pixels, which is also b bytes. For example, when a equals 3 and b equals 4, the RGB format image drawn by the application that conforms to the physical screen size of the FSD screen is shown in Figure 3.

[0065] Based on the above, if the RGB format image drawn by the application and conforming to the physical screen size of the FSD screen is converted to the FSC format required by the FSD screen and displayed on the FSD screen, the image content may be incomplete. To solve this problem, the FSD screen display method provided by this invention, after step S2100 above, first splits the first RGB format image drawn by the application according to the physical screen size.

[0066] Step S2200: Adjust the first image to the second image.

[0067] The second image is formed by dividing the first image into three sub-images on an average basis along the image width direction, and then stitching the three sub-images together sequentially along the image height direction.

[0068] In one example, with the first image as shown in Figure 3, the second image is specifically shown in Figure 4.

[0069] Step S2300: Convert the second image into the third image according to the image conversion rules.

[0070] The third image is an FSC format image, and the conversion rule is specifically the conversion rule from RGB format to FSC format.

[0071] In one example, with the second image as shown in Figure 4, the third image is shown in Figure 5. Therefore, when the FSD screen displays the third image in field sequence, it can achieve a complete display of the third image, that is, a complete display of the image content of the first image drawn by the application.

[0072] Based on steps S2100 to S2400 above, the display of the FSD screen can be implemented at the software level through the application processor. This eliminates the need for the DDIC to have the function of converting from RGB format to FSC format, reducing the limitations on the hardware selection of the DDIC. Furthermore, it also enables the complete display of the third image, that is, the complete display of the image content of the first image drawn by the application.

[0073] This invention provides a display method for an FSD screen, applied to an application processor in an electronic device, comprising: acquiring a first image in RGB format drawn by the application according to the physical screen size; adjusting the first image to a second image, wherein the second image is formed by dividing the first image into three sub-images on an even basis along the image width direction, and the three sub-images are sequentially stitched together along the image height direction; converting the second image into a third image according to an image format conversion rule, wherein the third image is an image in FSC format; and displaying the third image on the FSD screen. This method can achieve FSD screen display through the application processor at the software level, thus eliminating the need for the DDIC (Distributed Display Interface) to have RGB-to-FSC format conversion capabilities, reducing the limitations on DDIC hardware selection. Furthermore, it can also achieve complete display of the third image, that is, complete display of the image content of the first image drawn by the application.

[0074] In one embodiment of the present invention, the above step S2100 can be specifically implemented by the following steps S2110 and S2111.

[0075] Step S2110: Report the physical screen size to the application.

[0076] Step S2111: Receive the first image in RGB format drawn by the application based on the physical screen size.

[0077] In this embodiment, the physical screen size of the FSD screen is first reported to the application, instructing the application to draw a first image in RGB format with the same size as the physical screen. After the application draws the first image, it retrieves the first image from the application.

[0078] In one embodiment of the present invention, the above step S2110 can be implemented by the following step S2110-1.

[0079] Step S2110-1 instructs SurfaceFlinger to report the physical screen size to the application.

[0080] Based on the above steps S2110-1, the functionality of SurfaceFlinger in traditional technology can be used to report the screen's physical dimensions to the application. This reduces the practical difficulty of the FSD screen display method provided by this invention.

[0081] In one embodiment of the present invention, the display method of the FSD screen provided by the present invention further includes the following steps S2210 and S2211 before the above step S2200.

[0082] Step S2210: Determine the second image size based on the physical screen size.

[0083] In this embodiment, taking a physical screen size of a*b as an example, the second image size is determined to be a / 3*3b.

[0084] Step S2211: Request the first cache according to the size of the second image.

[0085] In this embodiment, after determining the size of the second image, a cache is allocated for the second image, denoted as the first cache. This first cache is used to store the second image obtained based on the above step S2200. Therefore, the FSD screen display method provided by this invention further includes the following step S2220 after the above step S2200.

[0086] Step S2220: Store the second image in the first cache.

[0087] In one embodiment of the present invention, the above step S2400 is specifically implemented by the following steps S2410 and S2411.

[0088] Step S2410: Store the third image in the second cache corresponding to the FSD screen.

[0089] Step S2411: The third image read from the second buffer is displayed on the FSD screen.

[0090] In this embodiment, after obtaining the third image based on step S2300, the third image is stored in a cache that the FSD can directly read, namely the second cache. Therefore, when the FSD screen is displaying an image, it can quickly read the third image from the second cache for display.

[0091] In one embodiment of the present invention, the above step S2200 is specifically implemented by the following steps S2230 and S2231.

[0092] Step S2230: Determine whether the display screen type is an FSD screen.

[0093] Step S2231: If so, adjust the first image to the second image.

[0094] In this embodiment, the type of the display screen is first determined. If the display screen is an FSD screen, the first image is adjusted to the second image. Otherwise, the first image is displayed directly. In this way, the normal display of images drawn by the application can still be achieved even when the type of the electronic device's display screen changes.

[0095] The present invention also provides an FSD screen display device 600, which is applied to an application processor in an electronic device, as shown in FIG6, including:
