Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a shutdown screen display method and a display device. Background Art

[0002] In current display devices, after the user chooses to shut down, the display device will directly turn off the display screen and enter the shutdown procedure in a black screen. In this case, the user does not know when the shutdown procedure ends.

[0055] In some embodiments, the controller includes a central processing unit, a video processor, an audio processor, a graphics processor, a RAM, a ROM, and a first interface to an nth interface for input / output.

[0056] In some embodiments, the display 260 includes a display screen component for presenting images, and a driving component for driving image display, which is used to receive image signals output from a controller, display video content, image content, and a menu control interface component and a user control UI interface, etc.

[0057] In some embodiments, the display 260 may be at least one of a liquid crystal display, an OLED display, and a projection display, and may also be a projection device and a projection screen.

[0058] In some embodiments, the tuner-demodulator 210 receives broadcast television signals via wired or wireless reception, and demodulates audio and video signals, such as EPG data signals, from a plurality of wireless or wired broadcast television signals.

[0059] In some embodiments, the communicator 220 is a component for communicating with an external device or server according to various communication protocol types. For example, the communicator may include at least one of a Wifi module, a Bluetooth module, a wired Ethernet module, and other network communication protocol chips or near field communication protocol chips, and an infrared receiver. The display device 200 can establish transmission and reception of control signals and data signals with the control device 100 or the server 400 through the communicator 220.

[0060] In some embodiments, the detector 230 is used to collect signals of the external environment or external interaction. For example, the detector 230 includes a light receiver, a sensor for collecting the intensity of ambient light; or, the detector 230 includes an image collector, such as a camera, which can be used to collect external environment scenes, user attributes or user interaction gestures; or, the detector 230 includes a sound collector, such as a microphone, etc., for receiving external sounds.

[0061] In some embodiments, the external device interface 240 may include, but is not limited to, any one or more of the following interfaces: a high-definition multimedia interface (HDMI), an analog or digital high-definition component input interface (component), a composite video input interface (CVBS), a USB input interface (USB), an RGB port, etc. It may also be a composite input / output interface formed by the above multiple interfaces.

[0062] In some embodiments, the controller 250 and the tuner-demodulator 210 may be located in different separate devices, that is, the tuner-demodulator 210 may also be located in an external device of the main device where the controller 250 is located, such as an external set-top box.

[0063] In some embodiments, the controller 250 controls the operation of the display device and responds to user operations through various software control programs stored in the memory. The controller 250 controls the overall operation of the display device 200. For example, in response to receiving a user command for selecting a UI object to be displayed on the display 260, the controller 250 can perform operations related to the object selected by the user command.

[0064] In some embodiments, the object may be any one of the selectable objects, such as a hyperlink, an icon or other operable controls. Operations related to the selected object include: displaying a page, document, image, etc. connected to the hyperlink, or executing a program corresponding to the icon.

[0065] In some embodiments, the controller includes at least one of a central processing unit (CPU), a video processor, an audio processor, a graphics processing unit (GPU), a RAM Random Access Memory (RAM), a ROM (Read-Only Memory, ROM), a first interface to an nth interface for input / output, a communication bus (Bus), etc.

[0066] The CPU processor is used to execute the operating system and application instructions stored in the memory, and to execute various applications, data and content according to various interactive instructions received from the outside, so as to finally display and play various audio and video contents. The CPU processor may include multiple processors. For example, it may include a main processor and one or more sub-processors.

[0067] In some embodiments, the graphics processor is used to generate various graphic objects, such as at least one of icons, operation menus, and user input command display graphics. The graphics processor includes an operator, which performs operations by receiving various interactive instructions input by the user and displays various objects according to display attributes; and a renderer, which renders various objects obtained based on the operator, and the rendered objects are used to be displayed on the display.

[0068] In some embodiments, the video processor is used to receive an external video signal and perform at least one of the following video processing operations, such as decompression, decoding, scaling, noise reduction, frame rate conversion, resolution conversion, and image synthesis, according to a standard codec protocol of the input signal, to obtain a signal that can be directly displayed or played on the display device 200.

[0069] In some embodiments, the video processor includes at least one of a demultiplexing module, a video decoding module, an image synthesis module, a frame rate conversion module, and a display formatting module. The demultiplexing module is used to demultiplex the input audio and video data stream. The video decoding module is used to process the demultiplexed video signal, including decoding and scaling. The image synthesis module, such as an image synthesizer, is used to superimpose and mix the GUI signal generated by the graphics generator according to the user input or itself with the scaled video image to generate an image signal for display. The frame rate conversion module is used to convert the input video frame rate. The display formatting module is used to receive the video output signal after frame rate conversion and change the signal to conform to the display format signal, such as outputting an RGB data signal.

[0070] In some embodiments, the audio processor is used to receive an external audio signal, perform decompression and decoding according to a standard codec protocol of the input signal, and perform at least one of noise reduction, digital-to-analog conversion, and amplification processing to obtain a sound signal that can be played in a speaker.

[0071] In some embodiments, the user may input a user command in a graphical user interface (GUI) displayed on the display 260, and the user input interface receives the user input command through the graphical user interface (GUI). Alternatively, the user may input a user command by inputting a specific sound or gesture, and the user input interface receives the user input command by recognizing the sound or gesture through a sensor.

[0072] In some embodiments, "user interface" is a medium interface for interaction and information exchange between an application or operating system and a user, which realizes the conversion between the internal form of information and the form acceptable to the user. A common form of user interface is a graphical user interface (GUI), which refers to a user interface related to computer operation displayed in a graphical manner. It can be an interface element such as an icon, window, or control displayed on a display screen of an electronic device, wherein a control may include at least one of icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, and other visual interface elements.

[0073] In some embodiments, the user interface 280 is an interface that can be used to receive control input (such as a physical button on the display device body, or other interfaces).

[0074] In some embodiments, the system of the display device may include a kernel, a command parser (shell), a file system, and an application. The kernel, shell, and file system together constitute the basic operating system structure, which allows users to manage files, run programs, and use the system. After power-on, the kernel starts, activates the kernel space, abstracts hardware, initializes hardware parameters, etc., runs and maintains virtual memory, schedulers, signals, and inter-process communication (IPC). After the kernel starts, the shell and user applications are loaded. After startup, the application is compiled into machine code to form a process.

[0075] like Figure 4 As shown, the system of the display device is divided into three layers, namely, the application layer, the middleware layer and the hardware layer from top to bottom.

[0076] The application layer mainly includes commonly used applications on TV and application frameworks. Common applications are mainly applications developed based on browsers, such as HTML5 APPs and native APPs.

[0077] The Application Framework is a complete program model that has all the basic functions required by standard application software, such as file access, data exchange, etc., as well as the user interfaces of these functions (toolbars, status bars, menus, dialog boxes).

[0078] Native apps can support online or offline, message push or local resource access.

[0079] The middleware layer includes various TV protocols, multimedia protocols, system components and other middleware. The middleware can use the basic services (functions) provided by the system software to connect various parts of the application system or different applications on the network, and can achieve the purpose of resource sharing and function sharing.

[0080] The hardware layer mainly includes HAL interface, hardware and driver. Among them, HAL interface is the unified interface for all TV chips to connect, and the specific logic is implemented by each chip. Drivers mainly include: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power driver, etc.

[0081] In the current display device 200, after the user chooses to shut down, the display device 200 will directly close the display screen and enter the shutdown procedure in a black screen. In this case, the user does not know when the shutdown procedure ends. If the user wants to perform other operations after the display device 200 is shut down, the user cannot know when the display device 200 ends the shutdown procedure, and therefore cannot perform other operations in time.

[0082] It can be seen that the above shutdown method cannot display the shutdown process of the display device 200, and the user may need to estimate when the display device 200 can complete the shutdown process based on his own judgment. The time estimated by the user may be too long or too short, and whether the time is too long or too short, it will affect the user's experience.

[0083] In order to solve the problem that the shutdown process of the current display device cannot be displayed during the shutdown process, a display device 200 that can display the shutdown process is provided in an embodiment of the present application.

[0084] The display device 200 can normally play content during the shutdown process, such as video content, picture content, etc. A shutdown screen with a gradually larger display area is displayed on the display interface of the normal playback content, thereby gradually blocking the display interface. As the shutdown screen gradually becomes larger, the area of ​​visible content that is not blocked on the display interface gradually becomes smaller, until the shutdown process is completed, and there is no visible content on the display interface, which is completely blocked by the shutdown screen.

[0085] Figure 5 FIG. 4 shows a schematic diagram of a shutdown screen according to some embodiments. Figure 5 Taking the shutdown process of 3 seconds and the black shutdown screen as an example, during this 3-second process, the black shutdown screen can be gradually displayed from the left side of the display interface to the right, and then the black area gradually increases, and the visible content area on the display interface gradually decreases. At the end of the shutdown process, the black screen completely covers the entire display interface.

[0086] like Figure 5 During the shutdown screen display process shown, the user can clearly understand the current shutdown status of the display device 200, and clearly know when the display device 200 completes the shutdown operation.

[0087] From the user's perspective, the time of the shutdown process is the time from selecting shutdown to the completion of shutdown, which can be called shutdown time; while from the perspective of the display device 200, it is the countdown time after the user selects shutdown. In fact, the shutdown time and the countdown time are the same.

[0088] The shutdown time of the display device 200 is not fixed, it can be 3s or 5s, and the specific time can be set by the user. Therefore, in the embodiment of the present application, the display device 200 also needs to obtain the target shutdown time set by the user in advance. Then, after the user chooses to shut down, the display device 200 uses the target shutdown time to start the shutdown countdown. After the shutdown countdown starts, the display device 200 enters the shutdown program, and at this time, the shutdown screen can be displayed on the display interface.

[0089] Figure 6 FIG. 2 shows a flow chart of a display device 200 displaying a shutdown screen according to some embodiments. Figure 6 , the display device 200 is provided with a controller 250, and all operations performed by the display device 200 are controlled by the controller 250. Specifically, in the process of the display device 200 displaying the shutdown screen, the controller 250 can be configured to: first, obtain the target shutdown time set by the user in the display device 200. Then, in response to the shutdown command input by the user, start the shutdown countdown using the target shutdown time. Finally, in the process of the shutdown countdown, control the display 260 to display a shutdown screen with a gradually increasing area on the current display interface, thereby gradually covering the display interface; and, when the shutdown countdown ends, the shutdown screen completely covers the display interface.

[0090] Before the display device 200 starts the shutdown countdown, the user can input a shutdown command to the display device 200 through the control device 100 such as a remote controller. For example, the user inputs a shutdown command to the display device 200 by pressing the power button on the control device 100; or the user inputs the voice content "shutdown" to the control device 100 while pressing the voice button on the control device 100, and the control device 100 sends the voice content "shutdown" to the display device 200, thereby inputting the shutdown command to the display device 200. If the display device 200 itself has a sound pickup function, the user can also directly input the voice content "shutdown" to the display device 200, thereby inputting the shutdown command to the display device 200.

[0091] In the display device 200 of the embodiment of the present application, a shutdown time setting page is also provided for the user. Several shutdown time options can be displayed on the shutdown time setting page, and the user can select a time to set as the target shutdown time according to his or her needs.

[0092] Figure 7 FIG. 1 is a schematic diagram showing a shutdown time setting page according to some embodiments. Figure 7 , the time options that can be displayed on the shutdown time setting page include 0s, 1s, 2s, 3s, 4s, 5s, etc. If the user wants to see the 2s shutdown screen, then the 2s shutdown time option can be selected; if the user wants to see the 5s shutdown screen, then the 5s shutdown time option can be selected.

[0093] In the above process of setting the shutdown time, the user can first input a first page display instruction to the display device 200, thereby controlling the display device 200 to display the shutdown time setting page. Then, the user can select a target shutdown time option on the shutdown time setting page, thereby inputting a first selection instruction to the display device 200, thereby controlling the display device 200 to set the shutdown time corresponding to the target shutdown time option selected by the user as the target shutdown time.

[0094] For the same shutdown screen, different shutdown times will affect the display progress of the shutdown screen, but will not affect the display method of the shutdown screen. Figure 5 Take the shutdown screen display method shown in as an example, when the user sets the target shutdown time to 2s, Figure 8 As shown in , the shutdown screen may only display two stages, namely, the stage of covering 1 / 2 of the display interface at 1 second and the stage of covering the entire display interface at 2 seconds. When the target shutdown time set by the user is 4 seconds, Fig. 9 As shown, the shutdown screen may be displayed in four stages, namely, stages of covering different display interface areas for 1s, 2s, 3s, and 4s.

[0095] In the process of the display device 200 setting the target shutdown time according to the user's selection, the controller 250 of the display device 200 may also be configured to: first, in response to a first page display instruction input by the user, control the display 260 to display the shutdown time setting page. Then, in response to a first selection instruction input by the user on the shutdown time setting page for selecting a target shutdown time option, set the shutdown time corresponding to the target shutdown time option as the target shutdown time.

[0096] It is understandable that if the shutdown time is 0s, or the shutdown time is very short, the display device 200 will not be able to display the gradually changing shutdown screen, or the displayed shutdown screen will not have an obvious change effect. In order to enable the user to intuitively feel the display process of the shutdown screen, and then intuitively understand that the shutdown process is in progress, in the embodiment of the present application, a preset time can also be set to determine whether the target shutdown time can be used to start the shutdown countdown.

[0097] If the target shutdown time is greater than the preset time, it means that the target shutdown time is long enough. At this time, if the display device 200 uses the target shutdown time to start the shutdown countdown, the process of gradual changes in the shutdown screen presented during the shutdown countdown will be very clear and obvious. If the target shutdown time is less than or equal to the preset time, it means that the target shutdown time is too short. At this time, if the display device 200 uses the target shutdown time to start the shutdown countdown, the process of gradual changes in the shutdown screen presented during the shutdown countdown will not be very obvious. Therefore, only when the target shutdown time is greater than the preset time, the display device 200 will respond to the shutdown command input by the user and start the shutdown countdown. When the target shutdown time is less than or equal to the preset time, the display device 200 will shut down directly without displaying the shutdown process and the shutdown screen.

[0098] In the process of the display device 200 displaying the shutdown screen, the controller 250 of the display device 200 can also be configured to: first, determine whether the target shutdown time is greater than the preset time. If the target shutdown time is greater than the preset time, in response to the shutdown command input by the user, start the shutdown countdown using the target shutdown time. If the target shutdown time is less than or equal to the preset time, control the display 260 to directly shut down.

[0099] In the above embodiment, Figure 5 The display process of the shutdown screen is described by taking the shutdown screen of the covering type shown in as an example. In some embodiments, the shutdown screen may also be of other types, such as the first type gradually covering from both sides of the display interface to the middle of the display interface, the second type gradually covering from the top of the display interface to the bottom of the display interface, the third type gradually covering from the bottom of the display interface to the top of the display interface, the fourth type gradually covering from the left side of the display interface to the right side of the display interface, the fifth type gradually covering from the upper right corner of the display interface to the lower left corner of the display interface, and so on.

[0100] In addition to some of the shutdown screen types listed above, the display device 200 can also provide more feasible screen switching methods as switching methods between the display interface and the shutdown screen, such as interface fading, interface falling, interface erasing, etc. These methods can all be applied to the shutdown screen display process in the embodiments of the present application, and will not be listed one by one in the embodiments of the present application.

[0101] As described in the above embodiment, there are many types of shutdown screens in the display device 200. In order to facilitate the user to make a selection, the display device 200 in the embodiment of the present application can also provide a screen type setting page for the user. The user only needs to input a second page display instruction to the display device 200 to control the display device 200 to display the screen type setting page. Several screen type options are displayed on the screen type setting page. The user can select the target screen type on the screen type setting page according to his or her needs, and then input a second selection instruction to the display device 200 to control the display device 200 to display the shutdown screen in the manner of the target screen type.

[0102] Fig.10 FIG. 1 is a schematic diagram showing a screen type setting page according to some embodiments. Fig.10 , the screen type setting page displays options such as the first type, second type, third type, fourth type, and fifth type.

[0103] In the process of setting the target screen type by the display device 200, the controller 250 of the display device 200 may be further configured to: first, in response to the second page display instruction input by the user, control the display 260 to display the screen type setting page. Then, in response to the second selection instruction input by the user on the screen type setting page for selecting the target screen type option, set the screen type corresponding to the target screen type option as the target screen type of the shutdown screen.

[0104] During the shutdown process, the display device 200 displays the shutdown screen according to the preset target screen type. As described in the above embodiment, there are many types of shutdown screens, so the display device 200 needs to further determine which target screen type is.

[0105] Fig.11 FIG. 4 shows a display schematic diagram of a first type of shutdown screen according to some embodiments. Fig.11If the target screen type is the first type, during the shutdown countdown of the display device 200, the shutdown screen can be divided into two parts, which move relatively from the left and right sides of the display interface to the middle of the display interface, thereby forming a shutdown process similar to the merging of curtains. Finally, the left and right parts of the shutdown screen intersect at the vertical center axis of the display interface, thereby completing the covering and blocking of the display interface. At this time, the overall area of ​​the shutdown screen is also the largest.

[0106] Fig.12 FIG. 4 shows a schematic diagram of displaying a second type of shutdown screen according to some embodiments. Fig.12 If the target screen type is the aforementioned second type, then during the shutdown countdown of the display device 200, the shutdown screen can gradually move from the top of the display interface to the bottom of the display interface, thereby presenting a shutdown process in which the shutdown screen covers and blocks the display interface from top to bottom.

[0107] Fig.13 FIG. 4 shows a schematic diagram of displaying a third type of shutdown screen according to some embodiments. Fig.13 If the target screen type is the aforementioned third type, then during the shutdown countdown of the display device 200, the shutdown screen can gradually move from the bottom of the display interface to the top of the display interface, thereby presenting a shutdown process in which the shutdown screen covers and blocks the display interface from bottom to top.

[0108] Fig.14 FIG. 4 is a schematic diagram showing a display of a fourth type of shutdown screen according to some embodiments. Fig.14 If the target screen type is the aforementioned fourth type, during the shutdown countdown of the display device 200, the shutdown screen can gradually move from the left side of the display interface to the right side of the display interface, thereby presenting a shutdown process in which the shutdown screen covers and blocks the display interface from left to right.

[0109] Fig.15 FIG. 5 shows a schematic diagram of displaying a fifth type of shutdown screen according to some embodiments. Fig.15 If the target screen type is the fifth type mentioned above, during the shutdown countdown of the display device 200, the shutdown screen can gradually move from the upper right corner of the display interface to the lower left corner of the display interface, thereby presenting a shutdown process in which the shutdown screen covers and blocks the display interface from the upper right to the lower left.

[0110] Taking the first type as an example, the controller 250 of the display device 200 needs to obtain the target screen type set by the user in the display device 200 and determine the target screen type before executing the shutdown process. If the target screen type is the first type, during the shutdown countdown, the shutdown screen is controlled to move relatively from the left and right sides of the display interface, thereby increasing the area of ​​the shutdown screen on the display interface.

[0111] If the target screen type is the second type, the third type, the fourth type or the fifth type, etc., the controller 250 specifically controls the display mode of the shutdown screen according to the target screen type.

[0112] In the aforementioned embodiments, the first selection instruction, the second selection instruction, etc. can be regarded as two processes of user operation, and the two processes are: the user first presses the direction key of the remote control device 100 to control the focus to the target option, and then presses the confirmation key of the remote control device 100.

[0113] In order to facilitate the user to understand the display method of the target screen type in advance when setting the target screen type, when the user controls the focus on the screen type setting page to be positioned on the target screen type option, the display device 200 can also display a preview page on the screen type setting page to dynamically display the shutdown screen display method or display effect corresponding to the target screen type.

[0114] Fig.16 A schematic diagram of a preview page according to some embodiments is shown. Fig.16 The preview page can be displayed at a position on the screen type setting page that does not block the screen type options, such as being set at the upper right corner or lower right corner of the screen type setting page. If the user focuses on the first type of option on the screen type setting page, the shutdown screen display mode corresponding to the first type will be dynamically displayed on the preview page.

[0115] In the process of displaying the preview page, the controller 250 of the display device 200 may be configured to control the display 260 to display the preview page on the screen type setting page when the focus on the screen type setting page moves to the target screen type option.

[0116] In the embodiment of the present application, the color of the shutdown screen is not fixed, and the user can pre-set the color of the shutdown screen according to his or her needs and preferences. The color of the shutdown screen is usually set to black by default, that is, if the user does not set the color of the shutdown screen, then each time the computer is shut down, the shutdown screen displayed by the display device 200 is black.

[0117] The display device 200 can provide the user with a screen color setting page for setting the color of the shutdown screen, and several color options can be displayed on the screen color setting page, such as gray, red, yellow, etc. The user can first input a third page display instruction to the display device 200, thereby controlling the display device 200 to display the screen color setting page. Then, the user selects a target color option on the screen color setting page, and then inputs a third selection instruction to the display device 200, controlling the display device 200 to determine the color corresponding to the target color option as the target color. For example, if the user selects the target color option as blue, the display device 200 determines that the target color is blue.

[0118] Fig.17 Schematic diagram of a screen color setting page according to some embodiments is shown. Fig.17 The screen color setting page may include color options such as black, gray, blue, brown, red, and yellow. After the user selects a color option, the display device 200 may determine the corresponding color as the target color.

[0119] In the process of setting the target color, the controller 250 of the display device 200 may be configured to: first, in response to the third page display instruction input by the user, control the display 260 to display the screen color setting page. Then, in response to the third selection instruction input by the user on the screen color setting page for selecting the target color option, determine the color corresponding to the target color option as the target color of the shutdown screen.

[0120] After the target color is set, during the shutdown process, the display device 200 can also control the shutdown screen to be displayed in the target color. In this process, the controller 250 of the display device 200 can also be configured to: first, obtain the target color set by the user in the display device 200 for the shutdown screen. Then, during the shutdown countdown, control the display 260 to display a shutdown screen with a gradually increasing area in the target color on the current display interface.

[0121] In order to further reflect the shutdown process, the display device 200 of the embodiment of the present application can also control the volume of the sound corresponding to the content of the display interface to gradually decrease when the shutdown screen gradually displays a larger area. When the shutdown countdown ends, or when the shutdown process ends, the volume of the played sound becomes the lowest value or becomes 0. Thus, the user is presented with a shutdown process in which the played screen gradually disappears and the played sound also gradually disappears.

[0122] If the content being played on the display interface does not have corresponding sound, then during the shutdown process, the display device 200 only controls the playing image to gradually disappear without controlling the volume to decrease.

[0123] In the above shutdown process, if the content currently played on the display interface of the display device 200 has a corresponding sound, the controller 250 of the display device 200 can also be configured to: during the shutdown countdown, control the volume of the sound corresponding to the content displayed on the display interface to gradually decrease. And, when the target shutdown countdown ends, the volume of the sound is reduced to the lowest volume value.

[0124] It is worth noting that the display interface in the embodiment of the present application refers to an interface with the same screen size as the display 260. The content played in the display interface may fill the entire display interface. In the above embodiments, the display process of the shutdown screen is described by taking the case where the content played fills the entire display interface as an example. In some embodiments, the content played in the display interface may not fill the entire display interface. For details, see Fig.18 In this case, since the size of the display interface is the same as the screen size, the shutdown screen can still be displayed on the display interface in the aforementioned various types of ways. Taking the first type as an example, see Fig.19 , and finally the shutdown screen can still achieve the purpose of covering and blocking the entire display interface.

[0125] In order to provide users with more shutdown screen effects, the shutdown screen in the embodiment of the present application can also be set to an image with specific content or an image with different colors, etc. The display device 200 can provide the user with a content setting page for setting different shutdown screen contents, and different content options can be displayed on the content setting page, such as picture content options, color content options, etc. If the user wants to set the content of the shutdown screen to his own photo, he only needs to select the picture content option on the content setting page, and then control the display device 200 to display the alternative photos or pictures, and the user can select the target photo from the alternative photos.

[0126] If the shutdown image is the target photo, then see Fig. 20 The final display effect of the shutdown screen is that a complete character image is finally displayed on the display interface.

[0127] In order to provide users with more shutdown screen effects, the transparency of the shutdown screen in the embodiment of the present application can also be set to different values. The display device 200 can provide users with a transparency setting page for setting different transparencies. Different transparency value options can be displayed on the transparency setting page, for example, 0%, 20%, 50%, 70%, 100%, etc. Among them, 0% means that the shutdown screen is not transparent, and 100% means that the shutdown screen is completely transparent. Users can select a target transparency value according to their needs or preferences, and then set the transparency of the shutdown screen.

[0128] Take the shutdown screen as an example, which is black and has a transparency of 50%. The display effect of the shutdown screen can be seen in Fig.21 In this case, the user can see the content originally played on the display interface and the display process of the shutdown screen that is gradually being displayed.

[0129] As can be seen from the above content, the display device 200 in the embodiment of the present application can first obtain the target shutdown time pre-set by the user in the display device 200 before entering the shutdown process. Then, after the user operates the display device 200 to shut down, the display device 200 uses the target shutdown time to start the shutdown countdown. During the shutdown countdown, the display device 200 can display a shutdown screen with a gradually increasing area on the current display interface, thereby realizing the display of the shutdown screen. At the end of the shutdown countdown, the shutdown screen will completely cover the display interface, thereby completing the shutdown process. During this shutdown process, the user can clearly understand the real-time shutdown situation to ensure the user's experience.

[0130] In order to solve the problem that the current shutdown method of the display device cannot display the shutdown process of the display device, a shutdown screen display method is also provided in the embodiment of the present application, which can be applied to the display device 200 in the aforementioned embodiment. The method may include the following steps: First, obtain the target shutdown time set by the user in the display device 200. Then, in response to the shutdown command input by the user, start the shutdown countdown using the target shutdown time. Finally, during the shutdown countdown, control the display 260 to display a shutdown screen with a gradually increasing area on the current display interface, thereby gradually blocking the display interface. At the end of the shutdown countdown, the shutdown screen completely blocks the display interface.

[0131] In some embodiments, the method may further include: determining whether the target shutdown time is greater than a preset time. If the target shutdown time is greater than the preset time, in response to a shutdown instruction input by a user, starting a shutdown countdown using the target shutdown time.

[0132] In some embodiments, the method may further include: first, obtaining a target screen type set by the user in the display device 200 for the shutdown screen. Then, determining the target screen type; if the target screen type is the first type, during the shutdown countdown, controlling the shutdown screen to move relatively from the left and right sides of the display interface, thereby increasing the area of ​​the shutdown screen on the display interface.

[0133] In some embodiments, the method may further include: first, obtaining a target color for the shutdown screen set by the user in the display device 200. Then, during the shutdown countdown, controlling the display 260 to display a shutdown screen with a gradually increasing area in the target color on the current display interface.

[0134] In some embodiments, the method may further include: during the shutdown countdown, controlling the volume of the sound corresponding to the content displayed on the display interface to gradually decrease. The volume of the sound is reduced to a minimum value when the target shutdown countdown ends.

[0135] In some embodiments, the method may further include: first, in response to a first page display instruction input by a user, controlling the display 260 to display a shutdown time setting page. Then, in response to a first selection instruction input by a user on the shutdown time setting page for selecting a target shutdown time option, setting the shutdown time corresponding to the target shutdown time option as the target shutdown time.

[0136] In some embodiments, the method may further include: first, in response to a second page display instruction input by a user, controlling the display 260 to display a screen type setting page. Then, in response to a second selection instruction input by a user on the screen type setting page for selecting a target screen type option, setting the screen type corresponding to the target screen type option as the target screen type of the shutdown screen.

[0137] In some embodiments, the method may further include: when the focus on the screen type setting page moves to the target screen type option, controlling the display 260 to display a preview page on the screen type setting page, wherein the preview page dynamically displays the shutdown screen display effect corresponding to the target screen type.

[0138] In some embodiments, the method may further include: first, in response to a third page display instruction input by a user, controlling the display 260 to display a screen color setting page. Then, in response to a third selection instruction input by a user on the screen color setting page for selecting a target color option, determining the color corresponding to the target color option as the target color of the shutdown screen.
