Description

Display device and startup interface display method

Technical Field

The application relates to the technical field of rotating televisions, in particular to a display device and a starting interface display method.

Background

The intelligent television equipment has an independent operating system and supports function expansion. Various application programs can be installed in the smart television according to the needs of the user, for example, social applications such as traditional video applications and short videos, and reading applications such as cartoons and books. The applications can display application pictures by utilizing a screen of the intelligent television, and rich media resources are provided for the intelligent television. Meanwhile, the intelligent television can also perform data interaction and resource sharing with different terminals. For example, the smart television can be connected with a mobile phone through a wireless communication mode such as a local area network and bluetooth, so as to play resources in the mobile phone or directly project a screen to display a picture on the mobile phone.

However, since the picture scales corresponding to different applications or media assets from different sources are different, the smart tv is often used to display pictures with different scales from the traditional video. For example, video resources shot by a terminal such as a mobile phone are generally vertical media resources with an aspect ratio of 9, 16, 9, 18, and 4 in equal proportion; and the pictures provided by the reading application are vertical resources similar to the aspect ratio of the book. The aspect ratio of the display screen of the smart television is generally 16, 9, 10 and other horizontal states, so when vertical media such as short videos and comics are displayed through the smart television, the vertical media cannot be normally displayed due to the fact that the picture proportion is not matched with the display screen proportion. Generally, the vertical media asset images need to be zoomed to be displayed completely, which not only wastes the display space on the screen, but also brings bad user experience.

Detailed Description

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following examples do not represent all embodiments consistent with the present application. But merely as exemplifications of systems and methods consistent with certain aspects of the application, as recited in the claims.

The term "module," as used in various embodiments of the present application, may refer to any known or later developed hardware, software, firmware, artificial intelligence, fuzzy logic, or combination of hardware and/or software code that is capable of performing the functionality associated with that element.

The term "remote control" as used in the embodiments of the present application refers to a component of an electronic device (such as the display device disclosed in the present application) that is capable of wirelessly controlling the electronic device, typically over a short distance. The component may typically be connected to the electronic device using infrared and/or Radio Frequency (RF) signals and/or bluetooth, and may also include functional modules such as WiFi, wireless USB, bluetooth, motion sensors, etc. For example: the hand-held touch remote controller replaces most of the physical built-in hard keys in the common remote control device with the user interface in the touch screen.

The term "gesture" as used in the embodiments of the present application refers to a user behavior used to express an intended idea, action, purpose, or result through a change in hand shape or an action such as hand movement.

The term "hardware system" used in the embodiments of the present application may refer to a physical component having computing, controlling, storing, inputting and outputting functions, which is formed by a mechanical, optical, electrical and magnetic device such as an Integrated Circuit (IC), a Printed Circuit Board (PCB) and the like. In various embodiments of the present application, a hardware system may also be generally referred to as a motherboard (motherboard) or a host chip or controller.

The rotary television is a novel intelligent television and mainly comprises a display and a rotary component. The display can be fixed on a wall or a support through the rotating assembly, and the placement direction of the display can be adjusted through the rotating assembly so as to be rotationally suitable for display pictures with different aspect ratios. For example, in most cases the display is positioned laterally to display video frames of equal aspect ratio 16, 9, 18. When the aspect ratio of a video picture is 9, 18, etc., the horizontally placed display needs to be scaled and black areas are displayed on both sides of the display. Therefore, the display can be rotated into a vertically-placed state by the rotating assembly to accommodate video pictures of 9.

The power-on starting process of the rotating television generally comprises the following steps: a user inputs a starting-up instruction; displaying a startup logo interface; displaying a starting-up animation interface; and displaying a homepage interface. For the startup logo interface, the startup animation interface and the homepage interface, the rotary television can display different contents in different states according to the display in the startup process. However, since the initial rotation state of the display when the operating system is powered on is a landscape state by default, in the process of displaying the power-on logo interface, the power-on animation interface and the homepage interface, the displayed picture rotates when detecting that the displayed picture does not accord with the current rotation state, so as to adapt to the current rotation state. For example, when the mobile terminal is started and operated in the vertical screen state, the display displays the startup logo interface, the startup animation interface and the homepage interface according to the default horizontal screen state, and after displaying for a period of time, the interfaces are rotated into the vertical screen state according to the detected current vertical screen state.

For example, the remote controller 100A may transmit an input signal, such as a power switch signal, a channel selection signal, a volume adjustment signal, etc., input by the user to the user interface 265, and then the input signal is transferred to the controller 250 through the user interface 265; alternatively, the remote controller 100A may receive an output signal such as audio, video, or data output from the user interface 265 via the controller 250, and display the received output signal or output the received output signal in audio or vibration form.

In some embodiments, a user may enter user commands on a Graphical User Interface (GUI) displayed on the display 275, and the user interface 265 receives the user input commands through the GUI. Specifically, the user interface 265 may receive user input commands for controlling the position of a selector in the GUI to select different objects or items. Among these, "user interfaces" are media interfaces for interaction and information exchange between an application or operating system and a user, which enable the conversion between an internal form of information and a form acceptable to the user. A common presentation form of a user interface is a Graphical User Interface (GUI), which refers to a user interface related to computer operations and displayed in a graphical manner. It may be an interface element such as an icon, window, control, etc. displayed in the display of the electronic device, where the control may include a visual interface element such as an icon, control, menu, tab, text box, dialog box, status bar, channel bar, widget, etc.

Alternatively, the user may input a user command by inputting a specific sound or gesture, and the user interface 265 receives the user input command by recognizing the sound or gesture through the sensor.

And a display formatting module for converting the signal output by the frame rate conversion module into a signal conforming to a display format of a display, such as converting the format of the signal output by the frame rate conversion module to output an RGB data signal.

The display video content may be from the video content in the broadcast signal received by the tuner-demodulator 210, or from the video content input by the communicator 220 or the external device interface 240. The display 275, while displaying a user manipulation interface UI generated in the display apparatus 200 and used to control the display apparatus 200.

And, the display 275 may include a display component for presenting a picture and a driving component for driving display of an image. Alternatively, a projection device and projection screen may be included, provided display 275 is a projection display.

The audio processor 280 is configured to receive an external audio signal, decompress and decode the received audio signal according to a standard codec protocol of the input signal, and perform audio data processing such as noise reduction, digital-to-analog conversion, and amplification processing to obtain an audio signal that can be played by the speaker 286.

Illustratively, audio processor 280 may support various audio formats. Such as MPEG-2, MPEG-4, advanced Audio Coding (AAC), high efficiency AAC (HE-AAC), and the like.

The audio output interface 285 is used for receiving an audio signal output by the audio processor 280 under the control of the controller 250, and the audio output interface 285 may include a speaker 286 or an external sound output terminal 287, such as an earphone output terminal, for outputting to a generating device of an external device.

In other exemplary embodiments, video processor 270 may comprise one or more chips. Audio processor 280 may also comprise one or more chips. And, in other exemplary embodiments, the video processor 270 and the audio processor 280 may be separate chips or may be integrated with the controller 250 in one or more chips.

And a power supply 290 for supplying power supply support to the display apparatus 200 from the power input from the external power source under the control of the controller 250. The power supply 290 may be a built-in power supply circuit installed inside the display apparatus 200 or may be a power supply installed outside the display apparatus 200.

For the rotatable display device 200, in practical applications, the rotating component 276 can bring the display 275 to adjust at any rotation angle to change the posture of the display 275. In general, the rotation assembly 276 may rotate the display 275 in a plane (i.e., a vertical plane viewed from the front of the user) in which the display screen is located, thereby causing the display 275 to be in different rotational states.

The rotation state is a plurality of specific states in which the display 275 is located, and may be set in a plurality of different forms according to the posture of the display 275. For example, landscape state, portrait state, tilt state, etc. The horizontal screen state and the vertical screen state are rotation states used by most users, and can be respectively suitable for a horizontal media asset scene and a vertical media asset scene. Therefore, in some embodiments of the present application, the landscape state and the portrait state may be referred to as a standard state. While the tilted state is generally a state in which the display 275 is rotated out of position or rotated excessively due to a failure of the rotating member 276, the user rarely intentionally rotates the display 275 to the tilted state. That is, in some embodiments of the present application, the tilted state may also be referred to as a non-standard state.

Wherein the landscape state refers to a state in which the length (width) of the display 275 in the horizontal direction is greater than the length (height) of the display 275 in the vertical direction when viewed from the front of the display 275; the vertical screen state is a state in which the length (width) of the display 275 in the horizontal direction is smaller than the length (height) of the display 275 in the vertical direction when viewed from the front of the display 275. Obviously, the vertical direction means substantially vertical in the present application, and the horizontal direction means substantially horizontal. And the other rotation states except the horizontal screen state and the vertical screen state are the inclined states. The rotation angle of the display 275 is different for different tilt conditions.

In some embodiments, the display content presented on the display 275 may differ in different rotational states, which may be embodied in specific playscreen content, UI interface layout, and the like. For example, the landscape state of the device 200 is displayed in some embodiments of the present application as shown in FIG. 5A. The mode of operation when the display 275 is in the landscape state may be referred to as the landscape viewing mode and the mode of operation when the display 275 is in the portrait state may be referred to as the portrait viewing mode.

The rotating assembly 276 can fix the display device 200 and rotate the display 275 under the control of the controller 250, so that the display 275 can be in different rotating states. The rotating assembly 276 may be secured to the back of the display 275, with the rotating assembly 276 being secured to a wall or support. The rotating assembly 276 may receive a control command from the controller 250 to rotate the display 275 in a vertical plane such that the display 275 is in a landscape state or a portrait state.

The display 275 may be rotated 90 degrees clockwise or counterclockwise by the rotation of the rotation assembly 276, adjusting the display 275 to a portrait position, as shown in FIG. 5B. In the vertical screen state, the display 275 may display the user interface corresponding to the vertical screen state and have the interface layout and the interaction mode corresponding to the vertical screen state. In the vertical screen media asset watching mode, a user can watch vertical screen media assets such as short videos and cartoons. Since the controller 250 in the display device 200 is further in communication connection with the server 300, the media asset data corresponding to the vertical screen can be acquired by calling the interface of the server 300 in the vertical screen state.

It should be noted that the horizontal screen state is mainly used for displaying horizontal media resources such as dramas and movies, and the vertical screen state is mainly used for displaying vertical media resources such as short videos and cartoons. The horizontal screen state and the vertical screen state are only two different display states, and do not limit the displayed content, for example, vertical media such as short videos, cartoons and the like can still be displayed in the horizontal screen state; horizontal media assets such as TV dramas and movies can still be displayed in the vertical screen state, and only the incompatible display windows need to be compressed and adjusted in the vertical screen state.

The different rotation states can be switched in real time, and since the interface layout and content presented by the display device 200 are different in the different rotation states, the display interface UI may be changed during the switching process. For example, during the process of switching from the landscape screen state to the portrait screen state, the display screen is switched from the landscape mode to the portrait mode so as to adapt to the display scale of the portrait mode. Typically the frame of the switching process may be a flipping action of the display pattern.

The rotational state of the display 275 when the display device 200 is powered on may be a landscape state or a portrait state, and generally depends on the rotational state of the display 275 when the display device 200 is powered off. For example, when the user turns off in the vertical screen state, the rotation state of the display 275 is turned on next time to be in the vertical screen state. For the display 275 in the vertical screen state, the start-up interface and the home interface in the vertical screen state should be displayed, but in the process of starting up the display device 200, the display screen may be turned over only after the home interface is displayed, that is, the default horizontal screen state is started, and after the start-up is completed, the home interface is displayed by switching the display state.

For example, taking an intelligent terminal device based on an android system as an example, after startup, a logo picture is displayed first, and meanwhile, a surfaceFlinger service is initialized to a landscape state, and startup animation is started. And initializing the windows manager into a horizontal screen state, and after the windows manager is initialized, notifying the surfeFinger service, wherein the surfeFinger service stops the boot animation (bootanimation). And then, the App is started to detect the state of the gravity sensor, and when the current rotation state is found to be a vertical screen state, the App performs self-adaptive rotation, so that the homepage interface is rotated to a vertical state.

Therefore, due to the display mode of the starting-up interface, the display contents watched by the user are as follows in sequence: and starting up to display a logo picture, a starting-up animation picture, a horizontal screen homepage interface and a self-adaptive rotation adjusted vertical screen homepage interface. However, since the display 275 is in the vertical screen state when the display device 200 is powered on, all interfaces displayed before the vertical screen homepage interface are in the inclined state, i.e., the startup logo picture, the startup animation picture, and the landscape homepage interface all have the problem of display errors.

In order to solve the above problem of display errors, some embodiments of the present application provide a method for displaying a booting interface, as shown in fig. 6 and 7, the method includes the following steps:

s1: and acquiring a starting-up instruction.

The boot instruction is a control instruction for controlling the boot process, which is input by a user, and may be a physical instruction or a digital instruction according to the boot starting manner. For example, the display device 200 may be powered on and started by a user turning on a power switch (key) on the display device 200, where the power-on command is an electrical signal generated when the user presses the power switch. When the user performs soft-start through a power key on the control device 100 such as a remote controller, the display device 200 may still be started to operate, and the power-on command is a control signal input by the control device 100.

The controller 250 may start running the operating system boot program in response to the boot instruction after acquiring the boot instruction. For example, an initialization process for performing each service, self-detection of the system, running a hardware driver, and starting a display control program, etc. The boot program may consume a certain amount of time to complete the boot program according to different operating systems, and thus during this time, the display device 200 may display the boot interface through the display 275.

In some embodiments, the power-on interface may include a power-on logo interface and a power-on animation interface. The content displayed on the power-on logo interface is usually a brand logo of the display device 200, and may be a static or dynamic graphic picture; the content displayed by the boot animation interface may be a specific boot animation set by the provider of the display device 200, or some promotional video frames. Generally, the boot flag interface is displayed according to the display content set in the boot program and the running of the boot program. The starting animation interface is displayed by starting animation service, such as bootanimation service, by running corresponding control program.

For example, when the boot animation is a promotional video image, the controller 250 calls bootanimation service along with the operation of the boot program, and the bootanimation service acquires the cached video file from the memory and plays the video file. Or after the bootanimation service is called, the bootanimation service acquires the video file from the server 300 through the connected server 300 to play.

In order to display the booting interface, the display device 200 may display different types of booting interfaces in different rotation states, that is, the booting interface may also include a horizontal booting interface and a vertical booting interface. Correspondingly, the transverse starting-up interface comprises a transverse starting-up sign interface and a transverse starting-up animation interface; the vertical starting interface comprises a vertical starting sign interface and a vertical starting animation interface.

S2: and responding to the starting-up instruction, and detecting the current rotation state of the display.

After receiving the power-on command, the controller 250 may first detect a current rotation state of the display 275, and determine a current posture of the display 275, so as to control the display of the power-on interface according to the current rotation state.

In practice, the controller 250 may detect the current rotation state of the display 275 through a posture sensor built in the display device 200. For example, an electronic level may be built in the display device 200, and after receiving the power-on command, the controller 250 may detect the current horizontal state of the display 275 through the electronic level, and when detecting that the horizontal state parameter of the current display 275 is within a reasonable error range, determine that the current rotation state of the display 275 is the landscape state; otherwise, when the horizontal state parameter of the current display 275 is detected not to be within a reasonable error range, the current rotation state of the display 275 is determined to be the vertical screen state.

In some embodiments, the position relationship between the gravity direction and the display 275 can also be detected by a gravitational acceleration sensor built in the display device 200 to determine the current rotation state. For example, after receiving the power-on command, the controller 250 may detect an angle between the current gravity direction and a width (or short) direction of the screen of the display 275 through the gravity acceleration sensor, so as to determine the current rotation state of the display 275. If the detected gravity direction is perpendicular to the screen widthwise direction of the display 275 (or the detected gravity direction is parallel to the screen widthwise direction of the display 275), determining that the current rotation state of the display 275 is a landscape state; if the detected gravity direction is parallel to the screen width direction of the display 275 (or the detected gravity direction is perpendicular to the screen short side direction of the display 275), it is determined that the current rotation state of the display 275 is the portrait state.

S3: and if the current rotation state of the display is the vertical screen state, controlling the display to display a vertical starting interface and detecting a vertical screen initialization process.

The controller 250 may control the display 275 to display different power-on interfaces according to the current rotation state detection result of the display 275. If the current rotation state of the display 275 is the vertical screen state, the display 275 is controlled to display a vertical power-on interface.

The vertical screen initialization process may also be detected after detecting that the current rotational state of the display 275 is a vertical screen state. Because it is different from the default rotational state of the display 275 of the operating system, if the booting is performed in the native booting manner of the operating system, the booting interface and the home interface may be tilted, which may affect the user experience. Therefore, the controller 250 will not start according to the native start-up mode of the operating system any more, adjust the display order of the startup interface, and display the homepage interface after detecting that the vertical screen initialization process is completed, thereby avoiding the image turning-over situation.

S4: and after the vertical screen initialization process is completed, closing the vertical starting interface and starting a vertical screen homepage display interface.

In practical application, by detecting the vertical screen initialization process, the vertical screen homepage display interface can be started after the vertical screen initialization process is completed. At this time, because the vertical screen initialization process is completed, the App corresponding to the home page interface no longer detects that the current picture does not conform to the rotation state, that is, the UI is in a locked form, so that the startup interface can be closed to directly start up and display the vertical screen home page interface, and the picture cannot be turned over.

Taking an operating system based on an android platform as an example, in the process of displaying the starting-up interface, the controller 250 may monitor a vertical screen setting process of the windows manager, so that after the windows manager completes the vertical screen setting, the starting-up animation interface is displayed, and after the starting-up animation interface is displayed, the vertical screen homepage interface is started to be displayed.

According to the above technical solution, the method for displaying the power-on interface provided in the above embodiment can detect the current rotation state of the display 275 after the power-on instruction is obtained, and can avoid the error of oblique display of the power-on interface by displaying the vertical power-on interface when the current rotation state is the vertical screen state. Meanwhile, in the process of displaying the startup interface, the controller 250 may also detect the vertical screen initialization process, so that after the vertical screen initialization process is completed, the vertical startup interface is closed, and the vertical screen homepage display interface is started, so that the homepage interface displayed on the display 275 is directly in a vertical UI layout, the situation of image turning does not occur, and the user experience is improved.

In some embodiments of the present application, the current rotation state of the display 275 may also be detected by an angle sensor built into the display device 200. An angle sensor may be provided on a rotating shaft of the driving motor in the rotating assembly 276 to detect a change in the rotational angle of the rotating assembly 276. Therefore, as shown in fig. 8, the step of detecting the current rotation state of the display further includes:

s201: acquiring the rotation angle of a driving motor of the rotating assembly;

s202: if the rotation angle is within a preset vertical screen rotation angle interval, determining that the current rotation state of the display is a vertical screen state;

s203: and if the rotation angle is within the preset horizontal screen rotation angle interval, determining that the current rotation state of the display is the horizontal screen state.

In this embodiment, after receiving the power-on command, the controller 250 may obtain the rotation angle of the driving motor of the rotating component 276 through the angle sensor. The rotation angle of the driving motor is an angle variation of the rotation shaft of the driving motor with respect to a set initial state to reflect the rotated angle of the display 275. For example, if the display 275 is set to have a corresponding posture of 0 in the landscape state, the angle sensor may detect that the rotation angle of the driving motor is 90 degrees when the display 275 is in the portrait state.

The detected rotation angle may be determined by determining which rotation state is equal to the specific value, thereby determining the current rotation state of the display 275. For example, when it is detected that the rotation angle of the driving motor is 0 degrees, it is determined that the current rotation state of the display 275 is the landscape state; when it is detected that the rotation angle of the driving motor is 90 degrees, it is determined that the current rotation state of the display 275 is the portrait screen state.

In practical applications, a certain mechanical return difference exists in the rotating assembly 276, and the using environment may have a certain influence on the rotating assembly 276, so that when the display 275 is rotated, the rotation angle may not be accurately controlled to a certain set value, and therefore, a rotation angle interval may be preset for each rotation state according to a statistical reasonable error range, so that when the rotation angle of the driving motor is within the preset rotation angle interval, it is determined that the display 275 is in a corresponding rotation state. If the rotation angle is within the preset vertical screen rotation angle interval, determining that the current rotation state of the display is the vertical screen state; and if the rotation angle is within the preset horizontal screen rotation angle interval, determining that the current rotation state of the display is the horizontal screen state.

For example, if the preset vertical screen rotation angle interval is (85 °,95 °), and the preset horizontal screen rotation angle interval is (-5 °,5 °), and if the rotation angle of the driving motor of the rotating assembly 276 is 87 ° as obtained by the angle sensor, since the rotation angle of 87 ° is within the preset vertical screen rotation angle interval (85 °,95 °), it is determined that the current rotation state of the display 275 is the vertical screen state.

In some cases, the rotation angle of the driving motor of the rotating assembly 276 is not within the vertical screen rotation angle interval and is not within the horizontal screen rotation angle interval. For example, if the angle sensor detects that the rotation angle of the driving motor of the rotating assembly 276 is 78 °, it can be determined from the rotation angle interval shown in the above example that the current rotation state of the display 275 is not the vertical screen state or the horizontal screen state. In this case, the operating system may default to the landscape state in order to display the opening machine interface. However, in this display mode, when the display 275 is close to the portrait state, the displayed tilt degree of the booting interface is large, and the display effect is not good.

Thus, in some embodiments, the appropriate rotational state may be determined by setting consecutive portrait and landscape corner intervals. An angle judgment threshold value can be preset, and the corner intervals on the two sides of the threshold value are respectively used as a vertical screen corner interval and a horizontal screen corner interval. For example, if the angle determination threshold is 45 °, the vertical screen angle section is (45 °,90 °), and the horizontal screen angle section is (0 °,45 °). When the rotation angle of the driving motor of the rotating member 276 is determined to be 78 ° by the angle sensor, it is determined that the rotation angle is within the vertical screen rotation angle interval (45 °,90 °), the display 275 is more likely to be in the vertical screen state, i.e., the current rotation state of the display 275 is determined to be in the vertical screen state.

In some embodiments, when the power-on interface includes a power-on logo interface and a power-on animation interface, the controller 250 may further control the display 275 to display the power-on logo interface after obtaining the power-on command. That is, after the user inputs the power-on command, the display 275 may first display a logo interface to indicate that the power-on program of the display apparatus 200 is currently started.

The Logo interface can be kept displayed until the boot program runs to the display boot animation interface. In some embodiments, as shown in FIG. 9, the power-on animation interface may be displayed according to the following steps:

s301: starting the starting animation interface;

s302: monitoring the initialization process of the vertical screen, and continuously displaying the starting mark interface in the monitoring process;

s303: and displaying the starting animation interface after monitoring that the initialization process of the vertical screen is completed.

Taking an operating system based on an android platform as an example, after the display 275 is detected to be in a vertical screen state by starting, the controller 250 initializes the surfacemaker service to be a vertical screen, and then starts to set the windows manager as the vertical screen and starts the boot animation at the same time. After the startup animation is started, animation playing can be performed firstly without using a logo interface, and after the initialization of the windows manager vertical screen is completed, animation playing is performed. At this time, the windows manager and the surfaceFlinger services are initialized and completed in a vertical screen mode, so that the phenomenon of UI rotation cannot occur in the starting animation playing process.

In the above embodiment, by detecting the rotation state of the display 275 and opening the interface display mode in the vertical screen direction when the rotation state is detected to be the vertical screen state, the interface rotation condition caused by changing the rotation state when the interface is started is alleviated, so that the experience is improved. While detecting the rotation state of the display 275, if the detected rotation state is the landscape state, the display of the booting interface may still be completed according to the native boot-up manner of the operating system, that is, in some embodiments of the present application, as shown in fig. 6, if the current rotation state of the display is the landscape state, the booting interface display method further includes the following steps:

s501: controlling the display to display a transverse starting interface and executing a transverse screen initialization process;

s502: and after the horizontal screen initialization process is completed, closing the horizontal starting interface and starting a horizontal screen homepage display interface.

That is, upon detecting that the current rotation state of the display 275 is the landscape state, the controller 250 may control the display 275 to display the landscape boot interface first. The horizontal startup interface and the vertical startup interface are different in picture proportion, for example, for a startup logo picture, the startup logo picture can be displayed in a picture or video form, the horizontal logo picture can have the same content as the vertical logo picture, but the picture proportion is different, and the picture proportion of the horizontal logo picture is 16:9, the picture scale of the vertical logo graph is 9:16.

similarly, the boot animation can be displayed in different picture scales in the same manner, and different video contents can be displayed in different rotation states. For example, when the boot animation is a promotional video such as an advertisement, different video contents can be displayed in different rotation states, that is, video contents suitable for a landscape application, such as a movie, a tv drama preview, etc., are displayed in a landscape state; and displaying video content suitable for vertical screen application, such as short video advertisements and the like, in the vertical screen state.

While controlling the display 275 to display the landscape boot image, the controller 250 may also control the execution of the landscape initialization procedure, such that after the landscape initialization procedure is completed, the landscape boot interface is closed and the landscape home interface is started. Taking an operating system based on an android platform as an example, the horizontal screen initialization process may include: initializing a surfaceFlinger service as a horizontal screen and starting a startup animation interface, and simultaneously setting a windows manager as the horizontal screen and displaying the startup animation interface; and finally, after the windows manager finishes the setting of the horizontal screen, closing the starting animation interface and starting the display horizontal screen homepage interface.

Unlike the vertical screen initialization process, in this embodiment, the controller 250 may directly display the power-on logo interface, initialize the surfaceflag service as the horizontal screen, and start the power-on animation interface after detecting that the current rotation state is the horizontal screen state. After the startup animation interface is started, the startup animation interface can be directly displayed without waiting for the completion of the horizontal screen setting process of the windows manager. In the process of displaying the power-on animation interface, the controller 250 may further detect a setting process of the windows manager, and may close the power-on animation interface and switch to display a cross screen homepage interface after detecting that the windows manager completes the cross screen setting. Because the current display state is consistent with the default rotation state form of the system, the boot animation can be directly displayed in the boot animation display mode after the boot animation interface is started, the boot logo does not need to be shielded, the display time of the boot logo interface and the boot animation interface can be balanced, and better user experience is brought.

In some embodiments of the present application, as shown in fig. 10, after the current rotation state of the display is the landscape state and the landscape home interface is finally displayed, the method further includes:

s601: detecting a rotation state of the display;

s602: if the rotation state of the display is a vertical screen state, changing the windows manager to be a vertical screen and changing the surfeFinger service to be a vertical screen;

s603: and vertically displaying the UI interface.

After displaying the landscape home interface, the controller 250 may also detect the rotation state of the display 275 in real time, and if it is detected that the rotation state of the display 275 is changed to the portrait state at a certain time, the windows manager and the surfefinger service may be changed to the portrait by setting, so as to display a vertical UI interface.

The change of the rotation state due to the display 275 can be input by the user. For example, the user inputs a switching instruction by means of the control device 100, the smart voice system, or the like; the controller 250 may control the rotation assembly 276 to rotate in response to the switching instruction, thereby adjusting the rotation state of the display 275. When the controller 250 detects that the display 275 has been rotated to the portrait state, the windows manager and surfaceflag services are changed to the portrait, and the displayed UI interface is rotated according to the setting results of the windows manager and surfaceflag services.

According to the above technical solution, the power-on interface display method provided by the present application may detect the current rotation state of the display 275 after receiving the power-on instruction, and display the power-on interface in different manners when the display 275 is in different rotation states. And the vertical starting interface can be displayed for the vertical screen state and the vertical screen initialization process is detected, so that after the vertical screen initialization process is completed, the vertical starting interface is closed to start the vertical screen homepage display interface. Therefore, the method can avoid the rotation of the display picture and relieve the problem of error display content through the shielding of the vertical starting interface in the vertical screen initialization process, and improve the user experience.

Based on the above method for displaying a booting interface, some embodiments of the present application provide a display device, including: a display 275, a rotating assembly 276, and a controller 250. The display 275 is configured to display a user interface, including displaying a power-on interface, a play screen, and the like. The rotating assembly 276 is connected to the display 275 and configured to rotate the display 275, so that the display 275 can be in any rotating state, including a landscape state or a portrait state. Both display 275 and rotating assembly 276 are electrically connected to controller 250.

The controller 250 is further configured to perform the following program steps:

s1: acquiring a starting-up instruction;

s2: detecting a current rotation state of the display in response to the power-on instruction;

s3: if the current rotation state of the display is a vertical screen state, controlling the display to display a vertical starting interface and detecting a vertical screen initialization process;

In the display device 200 provided in this embodiment, the controller 250 may detect the current rotation state of the display 275 by obtaining a power-on instruction input by a user, and may control the display 275 to display a vertical power-on interface if the current rotation state of the display 275 is a vertical screen state. Meanwhile, the controller 250 also detects a vertical screen initialization process in the operating system startup process, and closes the vertical startup interface and starts the vertical screen homepage display interface after detecting that the vertical screen initialization process is completed, so that the problems of rotation of a display frame and error in display content are avoided, and the user experience is improved.

The embodiments provided in the present application are only a few examples of the general concept of the present application, and do not limit the scope of the present application.
