Description

Technical Field

[0001] The present invention relates to the field of embedded technology, and in particular to a method and device for autonomously displaying a logo on a graphics card. Background Art

[0002] During the current computer startup process, the computer monitor screen displays in the following stages: the Basic Input Output System (BIOS) display stage, the system loading display stage, and the system operation display stage. During the BIOS display stage, the computer host uses the Unified Extensible Firmware Interface (UEFI) Graphics Output Protocol (GOP) driver to achieve display output through the graphics card. UEFI GOP is the protocol used in UEFI for operating graphics output. It allows the computer operating system to interact with the display hardware through a unified interface during and after the startup process, thereby achieving graphics display and output.

[0003] During the BIOS display phase, after the user presses the computer's power button, the motherboard powers on and begins running the BIOS program. The BIOS program initializes the computer's hardware, resets the graphics card, and loads the UEFI GOP graphics driver before invoking the graphics card, which then displays the logo image and BIOS interface on the screen. During this process, the screen displays no output for an extended period of time, from the time the motherboard powers on until the logo image appears on the screen. For example, after the motherboard is powered on, the screen may remain blank for 8 to 15 seconds. This excessively long interval between powering on the motherboard and displaying the logo image on the screen severely impacts the user experience.

[0004] In view of this, overcoming the defects of the prior art is an urgent problem to be solved in this technical field. Summary of the Invention

[0060] In the description of the present invention, the expression "A and / or B" (where A and B are used to formally represent specific characteristic contents) will be involved, and the corresponding expressions include the following three combinations: only A, only B, and a combination of A and B.

[0061] As used herein, "about," "substantially," or "approximately" includes the stated value and an average value that is within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).

[0062] In order to solve the above problems, Figure 1 As shown, an embodiment of the present invention provides a method for a graphics card to autonomously display a logo, including:

[0063] Step 10: Store the desired Logo image file in the Flash memory on the graphics card.

[0064] The specific content of the Logo image file is selected by those skilled in the art according to the specific usage scenario. The Logo image file includes a Logo image, which is ultimately displayed on the screen of a computer monitor through a graphics card.

[0065] Step 20: After the display hardware of the graphics card is initialized, the Logo image in the Logo image file is loaded from the Flash memory into the frame buffer memory.

[0066] The logo image is selected by those skilled in the art according to the specific usage scenario and is not limited here.

[0067] In an embodiment of the present invention, after the display hardware is initialized, the relevant display hardware is directly used to display the logo image in advance. Specifically, in order to instruct the graphics card to display the logo image, the logo image is pre-stored in the Flash memory on the graphics card. After the display hardware is initialized, the Flash memory is used to load the logo image into the graphics card's frame buffer memory (i.e., frame buffer).

[0068] Step 30: Obtaining the Logo image from the frame buffer memory to display the Logo image.

[0069] The present invention stores a logo image file to be displayed in a Flash memory on a graphics card; when the display hardware of the graphics card is initialized, the logo image is loaded from the Flash memory into a frame buffer memory, and the logo image is obtained from the frame buffer memory by the display hardware, so that the graphics card can obtain and display the logo image; there is no need to wait until the UEFI GOP graphics card driver is loaded, and the logo image can be displayed in advance after the display hardware is initialized, thereby shortening the time interval between powering on the mainboard and displaying the logo image on the screen.

[0070] The following is a detailed description of the method for a graphics card to autonomously display a logo according to an embodiment of the present invention:

[0071] First, write the Logo image into the Flash memory on the graphics card in advance, such as Figure 2 As shown, the step 10 includes:

[0072] Step 101: Convert the original Logo image into an image format that can be directly output by the graphics card to obtain the Logo image file to be displayed.

[0073] In order to avoid converting the image format when displaying the logo image, which causes display delay and prolongs the time when the screen has no output, the embodiment of the present invention converts the image format of the logo image in the Flash memory into an image format that can be directly output by the display hardware.

[0074] In an optional embodiment, the graphics card can directly output image formats including one or more of RGB565, RGB24, or ARGB32. The RGB565 format is suitable for applications that require storage space savings but do not require high color accuracy, and is often used in embedded systems, mobile devices, or graphical interfaces that require fast rendering. The RGB24 format is suitable for applications that require high-quality image display, and is often used in fields requiring precise color representation, such as image editing, printing, and web design. The ARGB32 format with an alpha channel is suitable for applications that require transparency information when displaying images, and is often used in fields requiring transparency, such as graphics rendering, image processing, and game development.

[0075] Step 102: Obtain the storage capacity of the Flash memory; when the storage capacity is greater than or equal to the file size of the Logo image file to be displayed, burn the Logo image file into the Flash memory to write the Logo image file into the Flash memory.

[0076] The embodiment of the present invention writes the logo image file into the Flash memory on the graphics card in advance, so that when the display hardware is loaded and can be used, it can directly instruct the display hardware to read the logo image and display it on the screen, without having to wait until the BIOS loads the graphics card driver and then read and display the logo image through the graphics card driver.

[0077] In an optional embodiment, a burning tool can be used to burn the Logo image file into the Flash memory. The burning tool is selected by those skilled in the art according to the specific usage scenario.

[0078] When burning a logo image file, the burning tool first determines the storage capacity of the Flash memory and determines whether the Flash memory can fully store the logo image file before burning it. The burning tool converts common image formats into a format that the display hardware can directly output, and then burns it into the Flash memory. The Flash memory also stores information such as the logo image file header and image parameters for the graphics card firmware to query and use.

[0079] In an optional embodiment, when the storage capacity is smaller than the file size of the logo image file to be displayed, the difference between the storage capacity and the file size of the logo image file to be displayed is obtained as the minimum expansion capacity; based on the minimum expansion capacity, an insufficient space command is generated, and the insufficient storage space command is sent to the user to provide an error prompt so that the user can adjust the storage capacity according to the minimum expansion capacity; in an embodiment, the insufficient storage space command can be sent by displaying a specified error code (for example, 0x0008) to the user, and carrying information such as the minimum expansion capacity. When the adjusted storage capacity is greater than or equal to the file size of the logo image file to be displayed, the logo image file is burned into the Flash memory to write the logo image file into the Flash memory.

[0080] In an optional embodiment, the logo image file in the Flash can be burned, updated and / or deleted.

[0081] After the graphics card firmware is initialized, it will determine whether there is a logo image file in the Flash memory and verify it; if there is a logo image file in the Flash memory, the graphics card display hardware will be initialized and the corresponding logo image will be displayed. The frame buffer memory is in the display processing module. The step 20 includes:

[0082] Step 201: After the mainboard is powered on, the BIOS program is initialized.

[0083] like Figure 3 As shown in the figure, when the computer power button is pressed, the computer's power management unit receives the power button signal and sends a power-on signal to the motherboard, instructing the motherboard to power on. Once the power supply is normal, the computer's central processing unit (CPU) will begin executing the BIOS program stored on the motherboard.

[0084] Step 202: The central processing unit runs the BIOS program to reset the graphics card and initialize the display hardware.

[0085] The BIOS is responsible for initializing the computer's hardware, including the Power-On Self-Test (POST) of the CPU, random access memory (RAM), graphics card, and hard drive. During this process, the BIOS checks whether these components are functioning properly. During this initialization process, the BIOS resets the graphics card to ensure it is functioning properly.

[0086] Step 203: The microcontroller unit of the graphics card obtains the logo image from the Flash memory through the BIOS program and loads it into the frame buffer memory.

[0087] The frame buffer is used to store image data to be displayed on the screen; the frame buffer is essentially a memory area that contains the color and brightness information of each pixel on the screen.

[0088] The embodiment of the present invention loads the Logo image into the frame buffer memory through a firmware program running on the MCU (Microcontroller Unit, abbreviated as MCU) of the graphics card.

[0089] When the graphics card's firmware is initialized, if the conditions for displaying the logo image are met, the graphics card's display hardware, including the display processing module and display interface, is initialized. The graphics card's firmware is software embedded in the graphics card, responsible for managing and controlling the graphics card's hardware functions. In one embodiment, the graphics card's firmware can be stored in the graphics card's Flash memory to ensure that it can be loaded and executed when the computer starts. The display processing module is mainly used for layer overlay and display. The display interface includes a High Definition Multimedia Interface (HDMI), a DisplayPort (DP), and a Video Graphics Array (VGA). The display processing module is responsible for generating a display signal for the logo image and transmitting the display signal to the display for display on the screen. After the display hardware is initialized, the graphics card reaches a state where it can output a display signal.

[0090] In order to explain the process of the display processing module controlling the graphics card to display the logo image, Figure 4 As shown, the step 30 includes:

[0091] Step 301a: the display processing module obtains the logo image from the frame buffer memory, performs layer overlay on the logo image, and obtains a display signal.

[0092] Step 302a: The display processing module outputs the display signal to the screen to display the Logo image on the screen.

[0093] In one embodiment, the display hardware may further include a display interface; after the display processing module obtains the image parameters from the Flash memory, it displays the Logo image on the screen by calling the display interface.

[0094] In the embodiment of the present invention, the graphics card reads the data in the frame buffer memory and converts it into a display signal that the display can understand, and sends the display signal to the display, so that the logo image is displayed on the screen of the display, thereby achieving the following Figure 3 The graphics card shown displays the logo independently.

[0095] Specifically, the Logo image file includes an image file header and image parameters. The image file header includes information about the software that generates or edits the Logo image file, and the image parameters are the parameters of the Logo image itself. Figure 5 As shown, the step 30 further includes:

[0096] Step 301b: Obtain the image parameters from the Flash memory, and determine the input resolution of the screen according to the image parameters.

[0097] In one embodiment, the display hardware may further include a display interface; after the display processing module obtains the image parameters from the Flash memory, it calls the display interface, displays the image parameters received by the interface, and determines the input resolution of the screen.

[0098] Step 302b: Acquire extended display identification data of the screen, and determine the output resolution of the screen according to the extended display identification data.

[0099] In one embodiment, the display processing module can obtain the screen's Extended Display Identification Data (EDID) and determine the screen's output resolution based on the EDID. EDID is a set of standard data provided by the display to the graphics card, including basic information and performance parameters of the display, such as the model, supported resolutions, and refresh rates. After receiving the EDID information, the graphics card parses it and determines optimal output resolution, refresh rate, and other parameters based on the display's performance parameters.

[0100] Step 303b: Obtain the image file header from the Flash memory; and read the Logo image from the frame buffer memory according to the image file header.

[0101] Step 304b: scaling the resolution of the logo image from the input resolution to the output resolution, and using the scaled logo image as the display signal.

[0102] The embodiment of the present invention runs the graphics card firmware to display a logo image on the screen in advance before the GOP driver is loaded, and the logo image is continuously displayed on the screen. When the BIOS program is loaded to the point where it can call the GOP driver, the GOP driver subsequently controls the graphics card to display the logo image.

[0103] like Figure 6 As shown, after step 30, the method further includes:

[0104] Step 401: The central processing unit continues to run the BIOS program to load the graphics card driver of the graphics card.

[0105] The graphics driver may be a GOP driver. In an optional embodiment, when the computer uses UEFI boot mode, the BIOS program will load the UEFI GOP graphics driver. UEFI GOP is part of the UEFI standard and is used for graphics output.

[0106] During the startup process, the BIOS program identifies and loads the graphics card driver. The graphics card driver initializes the graphics card's display hardware, establishes communication with the graphics card, and prepares the graphics card to display images. For example, when a computer starts, the motherboard's CPU executes a boot loader (e.g., UEFI), which loads the computer's operating system and graphics card driver. During this process, the GOP driver is loaded onto the motherboard's CPU and runs. Once the GOP driver runs, it communicates with the graphics card and configures it to display the logo image, operating system interface, and other graphical content.

[0107] Step 402: After the graphics card driver is loaded, the operating system runs the graphics card driver to configure the display mode of the screen.

[0108] The display mode is used to ensure that the graphics card can output the logo image in the correct format. In one embodiment, the display mode may include parameters such as output resolution and color depth. In an optional embodiment, the graphics card driver can query the graphics card's EDID information to obtain supported output resolutions, refresh rates, etc.

[0109] like Figure 7As shown, in the embodiment of the present invention, only after the GOP driver is loaded, will the graphics card be called through the GOP driver, and then the logo image will be output on the screen through the graphics card, and then the BIOS interface and the GRUB boot loader (GRandUnified Bootloader, abbreviated as GRUB) boot loader interface will be displayed, and finally the operating system interface will be entered. Among them, the BIOS interface usually includes the computer's hardware information, BIOS version, date and time, etc. The BIOS program searches for the boot loader (Boot Loader) on the device. The boot loader is responsible for loading the operating system kernel and starting it. After the boot loader successfully loads the operating system kernel, the computer's operating system starts to start until it enters the BIOS interface; during this process, the operating system will perform kernel initialization, hardware detection, memory management, file system mounting and other steps, and the screen will display pre-stored information such as the image to be displayed.

[0110] Among them, the picture to be displayed is selected by technical personnel in this field according to the specific usage scenario and is not limited here; in an optional embodiment, the picture to be displayed can be consistent with the Logo picture stored in the Flash memory, so that the image displayed on the screen remains unchanged during the process of the display hardware being loaded into the graphics card driver.

[0111] Step 403: The central processing unit obtains the image to be displayed through the BIOS program, and sends the image to be displayed to the graphics card.

[0112] Step 404: The operating system controls the graphics card through the graphics card driver so that the graphics card outputs the image to be displayed on the screen according to the display mode.

[0113] In one embodiment, the computer's operating system calls the graphics card driver, which loads the prepared logo image into video memory, automatically generates a display signal that matches the display mode, and sends the display signal to the connected monitor. After receiving the display signal, the monitor converts it into a visible image, thereby displaying the logo image on the screen.

[0114] In the prior art, the logo image cannot be displayed on the screen until the BIOS calls the graphics card driver. Embodiments of the present invention significantly reduce the time interval from motherboard power-up to the display of the logo on the screen. In one embodiment, depending on the computer monitor, it takes approximately 3 to 5 seconds for the graphics card hardware to complete initialization. After the graphics card hardware is initialized, the logo image can be displayed on the screen approximately 5 to 10 seconds earlier.

[0115] like Figure 8, is another schematic diagram of the architecture of the device for displaying a logo on a graphics card in accordance with an embodiment of the present invention. The device for displaying a logo on a graphics card in accordance with this embodiment includes one or more processors 21 and a memory 22. Figure 8 A processor 21 is taken as an example.

[0116] The processor 21 and the memory 22 may be connected via a bus or other means. Figure 8 The bus connection is taken as an example.

[0117] Memory 22, as a nonvolatile computer-readable storage medium, can be used to store nonvolatile software programs and nonvolatile computer executable programs, such as the method for autonomously displaying a logo on a graphics card in this embodiment. Processor 21 executes the method for autonomously displaying a logo on a graphics card by running the nonvolatile software program and instructions stored in memory 22.

[0118] The memory 22 may include high-speed random access memory and non-volatile memory, such as at least one disk storage device, flash memory device, or other non-volatile solid-state memory device. In some embodiments, the memory 22 may optionally include a memory remotely located relative to the processor 21, and such remote memory may be connected to the processor 21 via a network. Examples of such networks include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0119] The program instructions / modules are stored in the memory 22. When executed by the one or more processors 21, the method of the graphics card autonomously displaying the logo in the above embodiment is executed, for example, each step of the method of the graphics card autonomously displaying the logo in the embodiment of the present invention described above is executed.

[0120] An embodiment of the present invention further provides a non-volatile computer storage medium, wherein the computer storage medium stores computer executable instructions, and the computer executable instructions are executed by one or more processors, for example Figure 8 A processor 21 can enable the above one or more processors to execute the method for the graphics card to autonomously display the logo in the specific embodiment of the present invention, for example, execute the various steps of the method for the graphics card to autonomously display the logo in the embodiment of the present invention described above; it can also realize Figure 8 The modules and units described above; or executing the method for the graphics card to autonomously display the Logo in the specific embodiment of the present invention, for example, executing the steps of the method for the graphics card to autonomously display the Logo in the embodiment of the present invention described above; or Figure 8 The various modules and units described.

[0121] It is worth noting that the information interaction, execution process, etc. between the modules and units within the above-mentioned devices and systems are based on the same concept as the processing method embodiment of the present invention.
