[0038] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0039] The startup screen is a brand or logo screen that appears on the screen after you press the computer power button but before the operating system loads. Figure 1 The display method of the boot screen in the prior art is shown, such as Figure 1 As shown, the method includes the following steps: step 101, power on; step 102, EC (Embedded Controller) sequence start; step 103, BIOS (Basic Input Output System) power-on self-test to BDS (boot device selection) stage; step 104, displaying the BIOS boot screen; step 105, ACPI (Advanced Configuration and Power Management Interface) enabled; step 106, OS (Operation System) enabled.

[0040] Using this method, the boot screen is usually integrated into the BIOS and will not be displayed until the BIOS self-test reaches the late BDS stage. Under normal circumstances, that is, when the computer is started from a normal shutdown state (at least one of the power adapter or the battery is connected), it takes 4-5 seconds of black screen to see the boot screen. In special circumstances, when the computer is started from a mechanical shutdown state (the battery and the power adapter are both disconnected), it takes about 40 seconds of black screen to see the boot screen. In response to this problem, the present disclosure proposes a solution that can display the boot screen in a very short time after pressing the power button.

[0041] According to a first aspect of an embodiment of the present disclosure, a method for displaying a computer startup screen is provided. Figure 2 The following is a schematic diagram showing the implementation process of a method for displaying a computer startup screen according to an embodiment of the present disclosure. Figure 1 ,like Figure 2 As shown, the method includes:

[0042] Step 201, in response to BIOS entering the platform initialization entry stage, determines whether the display screen is in a ready state.

[0043] When the power button is pressed, the BIOS starts up and executes its self-test program. In the early stage of the self-test, there is an initialization entry phase (PEI). In this phase, the BIOS detects whether the display has completed its initialization process and is ready to receive and display image data.

[0044] Step 202: If the display screen is in a ready state, the embedded controller EC is used to control the display screen to display a boot screen.

[0045] If the display is in the ready state, the BIOS will send a signal or command to the EC to inform it that the display is ready and can now display the boot screen. After receiving this signal, the EC will control the display to display the boot screen.

[0046] Compared with the method in the prior art that displays the boot screen only from the BIOS self-check to the BDS stage, the method of this embodiment realizes the display of the boot screen in the PEI stage before the BDS stage, that is, using EC. The black screen time from pressing the power button to displaying the boot screen is significantly shortened, and the boot screen is displayed almost at the same time as the power button is pressed. In addition, this embodiment only needs to complete the development of BIOS and EC firmware, and ensure that the panel firmware can support the built-in boot screen to implement this solution. It avoids embedding the boot screen in the BIOS, and effectively optimizes the BIOS space.

[0047] In one embodiment of the present disclosure, if the display screen is in a ready state, the display screen is controlled by the EC to display a boot screen, which can be specifically achieved through the following steps: if the display screen is in a ready state, a boot screen display instruction is sent to the EC; the EC receives the boot screen display instruction, and displays the boot screen on the display screen by sending a backlight system control signal and a boot screen control signal.

[0048] In this embodiment, if the display screen is already in the ready state, the BIOS sends a boot screen display instruction to the EC. After receiving this instruction, the EC sends corresponding control signals to the backlight system and image control system of the display screen. The backlight system control signal is used to control the light source behind the display screen so that the user can see the image displayed on it. The boot screen display signal is used to display the boot screen on the screen. After these signals are sent to the display screen, the display screen will display the boot screen.

[0049] In one embodiment of the present disclosure, the method further includes: in response to enabling the advanced configuration and power interface (ACPI), sending a startup screen closing instruction to the EC; the EC receives the startup screen closing instruction and closes the startup screen on the display screen.

[0050] When ACPI is enabled, it indicates that the operating system is about to be entered. This means that the boot screen can be turned off so that the operating system desktop can be displayed later. Specifically, the boot screen is displayed throughout the entire self-test phase of the BIOS until ACPI is enabled, at which time the BIOS sends an instruction to the EC to turn off the boot screen. After receiving the instruction, the EC sends a signal to the display screen, instructing the display screen to stop displaying the boot screen. After receiving this signal, the display screen immediately stops displaying the boot screen.

[0051] In order to better understand the above embodiment, a specific embodiment is provided below for illustration. Figure 3 As shown, the implementation includes the following steps:

[0052] Step 301, power on: the user presses the power button of the computer, the computer starts to receive power supply and starts its startup sequence.

[0053] Step 302, EC sequence starts: After the power is turned on, the EC begins to execute its initialization sequence, preparing to monitor and coordinate the operation of the computer hardware components.

[0054] Step 303, BIOS starts self-test to PEI stage: BIOS starts up and executes its self-test program, and enters the early stage, namely, PEI stage.

[0055] Step 304, obtain CPU EDP VDD enable status: In the PEI stage, the BIOS will check the CPU EDP (Embedded Display Port) electrical signal (VDD) enable status. If VDD is enabled, the EDP interface can work normally and is ready to receive display data.

[0056] Step 305, displaying the startup screen: After the EDP works normally, the BIOS sends a command to the EC to enable the startup screen of the display screen through the EC.

[0057] Step 306, BIOS continues to enter the BDS stage: the BIOS self-test program continues to execute and enters the next stage, ie, the BDS stage.

[0058] Step 307, continuously displaying the boot screen: continuously displaying the boot screen when the BIOS enters the BDS stage from the PEI stage and during the entire BDS stage.

[0059] Step 308, ACPI is enabled.

[0060] Step 309, OS activation: Once ACPI is activated, BIOS sends a command to EC to notify it to turn off the startup screen. In this way, when the operating system is loaded and running, the startup screen or desktop of the operating system will be displayed.

[0061] In one embodiment of the present disclosure, after the startup screen is displayed on the display screen, the method further includes the following steps: responding to an event in which a preset function key is pressed, closing the startup screen, and displaying a function interface corresponding to the preset function key on the display screen.

[0062] The preset function key is a specific key configured in advance, which is related to certain specific functions or settings. Once the preset function key is detected to be pressed, the BIOS will immediately notify the EC to close the currently displayed boot screen. Then, the function interface corresponding to the preset function key is immediately presented on the display screen. This function interface can be an interface for computer hardware configuration, or it can be a shortcut operation interface for quickly starting a specific service, which can be set according to actual needs or application scenarios. The first and second involved in this embodiment are only for descriptive purposes, and cannot be understood as indicating that the number of preset function keys is two. In actual applications, the number of preset functions can be increased or decreased according to actual conditions.

[0063] This embodiment improves the flexibility and usability of the computer and provides a more convenient access method for users.

[0064] In one embodiment of the present disclosure, the preset function keys include a first preset function key and a second preset function key; accordingly, the function interface corresponding to the first preset function key is the BIOS setting interface, and the function interface corresponding to the second preset function key is the boot manager interface.

[0065] In this embodiment, two preset function keys are provided, including a first preset function key and a second preset function key. For example, the first preset function key is set to the F2 key, and the corresponding function is to start the BIOS setup interface. After detecting that the F2 key is pressed, the BIOS setup interface is jumped from the boot screen. For example, the second preset function key is set to the F12 key, and the corresponding function is to start the manager interface. After detecting that the F12 interface is pressed, the boot screen is jumped to the boot manager interface. It can be understood that F2 and F12 are only illustrative examples here, and are not limited to these two keys in actual applications.

[0066] This embodiment can quickly jump to the function interface required by the user through the preset function keys while the boot screen is displayed, thereby improving the computer operation efficiency and user experience.

[0067] In one embodiment of the present disclosure, if the computer is in a sleep state or a shutdown state, in response to an event in which a one-key recovery button or a one-key battery trigger button is pressed, a function interface corresponding to the one-key recovery button and the one-key battery trigger button is displayed on the display screen by enabling the backlight system.

[0068] The above embodiment describes the operation after the user presses the power button. On this basis, this embodiment further expands the operation response when the computer is in sleep mode or shutdown mode. The one-key recovery button and the one-key battery trigger button are two special function keys on the computer. The one-key recovery button is usually used to restore the computer system to a preset state or time point. The one-key battery trigger button is a button related to the battery management function of the computer. The specific functions of the two buttons vary with the brand and model of the computer. Specifically, in this embodiment, when the computer is in sleep mode or shutdown mode, if the user presses the one-key recovery button or the one-key battery trigger button. EC will immediately enable the backlight system to provide the necessary backlight for the display. Unlike the boot process, EC will not trigger the display of the boot screen at this time. Instead, it will directly jump to the function interface corresponding to the one-key recovery button or the one-key battery trigger button.

[0069] In order to better understand the above embodiment, another specific embodiment is described below. In this embodiment, the first preset function key is the F2 key and the second preset function key is the F12 key. Figure 4 As shown, this embodiment includes the following steps:

[0070] Step 401: Press the power button on the computer;

[0071] Step 402: EC sequence starts;

[0072] Step 403: Does the EC enter the S0 state (working state)? If yes, go to step 404; if no, go to step 407;

[0073] Step 404: BIOS self-check to PEI stage;

[0074] Step 405: BIOS obtains LCD (liquid crystal display) VDD EN (power enable) status;

[0075] Step 406: BIOS sends a command to EC;

[0076] Step 408: Does EC receive the BIOS command? If yes, execute step 409; if no, execute step 407;

[0077] Step 409: Turn on the backlight function of the LCD and the function of displaying the boot screen;

[0078] Step 410: Display the boot screen;

[0079] Step 411: BIOS continues self-checking to the BDS stage; at the same time, detect whether F2 and F12 are pressed? If yes, execute step 418; if not, continue to execute step 412;

[0080] Step 412: Continuously display the boot screen;

[0081] Step 413: ACPI is enabled;

[0082] Step 414: BIOS notifies EC to turn off display of the boot screen;

[0083] Step 415: EC turns off the LCD's function of displaying the startup screen;

[0084] Step 416: Enter the OS and the solution ends.

[0085] When the computer is in sleep state or turned off:

[0086] Step 417: Press the one-key recovery button or the one-key battery trigger button;

[0087] Step 418: Notify the EC to turn off the display of the startup screen;

[0088] Step 419: EC turns off the function of displaying the startup screen;

[0089] Step 420: Display the BIOS setup interface or the boot manager interface or the one-key recovery interface or the one-key battery trigger interface.

[0090] According to a second aspect of an embodiment of the present disclosure, a display device for a startup screen is provided, such as Figure 5 As shown, the device includes the following modules:

[0091] A response module 501 is used to respond to the basic input and output system BIOS entering the platform initialization entry stage to determine whether the display screen is in a ready state;

[0092] The display module 502 is used to control the display screen to display a boot screen through the embedded controller EC if the display screen is in a ready state.

[0093] In one embodiment of the present disclosure, the display module 502 is also used to send a display boot screen instruction to the EC if the display screen is in a ready state; the EC receives the display boot screen instruction and displays the boot screen on the display screen by sending a backlight system control signal and a boot screen control signal.

[0094] In one embodiment of the present disclosure, the display module 502 is further configured to respond to an event in which a preset function key is pressed, close the startup screen, and display a function interface corresponding to the preset function key on the display screen.
