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 aspect ratios of 9:16, 9:18, 3:4 and the like; 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 intelligent television is generally in a transverse state of 16:9, 16:10 and the like, so when vertical media such as short videos, cartoons and the like are displayed through the intelligent television, vertical media pictures cannot be normally displayed due to the fact that the picture ratio is not matched with the display screen ratio.

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 commonly used presentation form of the 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, a window, a control, etc. displayed in the display screen of the electronic device, where the control may include a visual interface element such as an icon, a control, a menu, a tab, a text box, a dialog box, a status bar, a channel bar, a 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 the video decoding module is used for processing the video signal after demultiplexing, including decoding, scaling and the like.

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

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.

In the technical solution provided in the present application, the starting process refers to a process in which a user performs a starting operation, for example, by pressing (touching) a start key on the control device 100, the display device 200 is controlled to start and operate; or by pressing (touching) a power key on the display device 200, the display device 200 is controlled to start operation. After the display device 200 is started, the hardware in the display device 200 is first powered on to operate, and then the operating system program is executed to enter the control homepage. Meanwhile, starting of the operating system and page initialization consume a certain time, so that the brand logo picture (logo picture) and/or the boot animation can be played in the time, and the time for waiting for booting of the user is filled.

FIG. 5 is a schematic diagram of a landscape state boot animation according to some embodiments of the present application; FIG. 6 is a schematic diagram of a vertical screen state boot animation according to some embodiments of the present application. The boot animation displayed on the display 275 may be a designated transition picture built into the operating system, or may be a third-party video resource displayed on the display device 200 for commercial purposes, for example, the boot animation may be a video recommendation resource such as a trailer pushed according to user preferences, or an advertisement video resource.

The power-on animation resource file may be stored in the memory 260 of the display device 200 by being directly called in the memory 260 of the display device 200 when the power-on program starts running. The memory 260 may obtain a plurality of boot animation resources with different contents from the server 300 (or a network environment) through a background program in a normal operation process of the display device 200, so as to respectively display at different boot times, that is, the boot animations at each boot are different, thereby avoiding a monotonous display effect. The boot animation resource file can also be obtained from the server 300 in real time after the boot program is started, so as to reduce the occupation of the storage space of the memory 260.

When the power-on animation resources are acquired from the server 300 in real time, the display apparatus 200 needs to be in a networked state. However, since the display device 200 is just started, the network environment is likely to be unstable, or the resource file cannot be downloaded from the server 300 in time, which causes the transition of the booting page to be not smooth or the waiting time to be long. Therefore, in order to make the transition of the booting page smoother, a standby booting animation resource may be stored in the memory 260, and when the resource file cannot be downloaded within a predetermined time during the booting process, the standby booting animation resource may be called. Thus, the memory 260 does not need to store too many resource files, and can also ensure that different pictures are displayed each time the computer is started.

The boot animation presented is also different for different gestures of the display 275. The difference can be embodied in different contents, and can also be embodied in different display proportions of animation resources. For example, when the display 275 is in the landscape state, a horizontal scale form of a power-on animation, such as a movie trailer, regular advertisement, etc., may be selected for play; when the display 275 is in the vertical screen state, it may be selected to play a vertical scale form of boot animation, such as a short video APP.

Wherein the landscape state is 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 is substantially vertical in the present application, and the horizontal direction is also substantially horizontal, depending on the installation/placement position of the display device 200. The horizontal screen state is mainly used for displaying horizontal media resources such as TV dramas and movies, and the vertical screen state is mainly used for displaying vertical media resources such as short videos and cartoons.

It should be noted that 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 and cartoons 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.

In practice, the state of the display 275 at power-on will generally depend on the state of the display 275 at the last time the user turned off. For example, the display 275 was in the landscape state the last time the user turned off the display device 200, and the display 275 was also in the landscape state this time it was turned on. Similarly, when the user turns off the display device 200 the last time, the display 275 is in the vertical screen state, and then the display 275 is in the vertical screen state when the user turns on the display device this time.

Obviously, for the rotatable display device 200, the display 275 is in other positions, which may be different from the actual use of the display device, and the display 275 is not limited to the above two positions. For example, rotated to other predetermined tilt states by the rotating assembly 276; or the display 275 is in a tilted state due to a power failure or other malfunction during the last rotation of the display 275 by the user; or the display apparatus 200 is artificially rotated to the tilted state during the power-off. In this application, the postures that the display 275 can take may be all referred to as a rotation state. The rotational states further include a standard state and a non-standard state.

The standard state refers to a state that can be directly obtained by adjustment through the rotating component 276 according to the viewing needs of the user, and may include a horizontal screen state, a vertical screen state, and the like. And, the standard state may further include other adjustable states, such as a state of being inclined by 45 degrees, etc., according to the display requirement. The non-standard state is distinct from the standard state and may be any intermediate state of the display 275 during switching between the two standard states. For example, when the user instructs to switch from the landscape screen state to the portrait screen state through the control device 100, the rotating component 276 rotates the display 275, and the display 275 is in the middle position during the period when the portrait screen state is not reached. If a power loss or other malfunction is encountered at this time, causing the display 275 to stay in any of the intermediate states, the display 275 is in a non-standard state.

When the display 275 is in the non-standard state, the display 275 is usually in the inclined state, and in this state, the picture displayed on the display 275 is also inclined, which not only affects the viewing experience of the user, but also easily causes an abnormality when the display 275 selects a resource. For example, when the display 275 rotates clockwise from the landscape state beyond 45 degrees and stops, the display 275 is closer to the portrait state, and at this time, when the display 275 still displays according to the landscape state, the inclination of the display screen is large, which seriously affects the viewing experience of the user. Also, the tilting state of the display 275 is generally detected by a gravitational acceleration sensor within the rotatable display device 200 in order to adjust the play screen. For example, when the display 275 is closer to the portrait state, the display 275 may rotate the display 90 degrees counterclockwise to accommodate the portrait state.

However, in the process of starting up, part of programs of the control system are not completely started up, and the display picture cannot be adjusted through the picture quality adjusting program, so that the starting-up animation cannot be rotated in the process of starting up. To improve the display quality of the boot animation, in the present application, different boot animations may be displayed when the display 275 is in different rotational states.

As shown in fig. 7, the boot animation display method provided by the present application may specifically include the following steps, that is, the controller is configured to:

s1: in response to activation of the display device, a current rotational state of the display is detected.

In practical applications, after the user starts the operation of the display device 200 by controlling the on/off key of the apparatus 100 or the power key of the display device 200, the controller 250 may detect the rotation state of the display 275 in response to the start action. The specific rotation state detection method may be performed by the gravity direction measured by the gravitational acceleration sensor built in the display device 200, or may be performed by the current rotation angle of the rotating assembly 276.

For the measurement mode of the gravitational acceleration sensor, after the display device 200 is started, the controller 250 may obtain a gravitational acceleration direction sensed by the gravitational acceleration sensor, that is, determine a vertical direction; and then the current rotation state of the display 275 is determined by determining the position relationship between the display 275 and the direction of the gravitational acceleration. For example, if the direction of the gravitational acceleration is detected to be parallel to the short side direction of the display 275, it is determined that the current display 275 is in the landscape state in the standard state; if the direction of the gravitational acceleration is detected to be parallel to the long side direction of the display 275, it is determined that the display 275 is currently in the portrait state in the standard state. If it is detected that the gravitational acceleration direction is not parallel to the long side direction and is not parallel to the short side direction of the display 275, it is determined that the display 275 is currently in the non-standard state.

With respect to the manner in which the rotating assembly 276 is detected, after the display device 200 is activated, the controller 250 may detect the rotation angle of the rotating assembly 276 and obtain the rotation status of the display 275. For example, rotating assembly 276 is at an initial 0 degree angle when display 275 is in the landscape state. If the rotation angle of the rotating assembly 276 is detected to obtain that the current rotation angle of the rotating assembly 276 is 0 degrees, the display 275 is determined to be in the landscape state; if the current rotation angle of the rotating assembly 276 is +90 degrees, which is obtained by detecting the rotation angle of the rotating assembly 276, the display 275 is determined to be in the vertical screen state; if it is determined that the rotation angle of the rotating assembly 276 is 36 degrees at the present time by detecting the rotation angle of the rotating assembly 276, it is determined that the display 275 is in the non-standard state.

It should be noted that the standard state is not limited to the horizontal screen state and the vertical screen state, and may be in other states according to the display requirement. Therefore, all the preset states adjusted by the rotating member 276 are classified as the standard states in the present application, for example, in some scenes, the screen display may be performed in such a manner that the display 275 is tilted by 45 degrees, and thus the posture of the display 275 in the 45 degree tilted direction may also be regarded as the standard state. Accordingly, the display 275 may be rotated clockwise or counterclockwise as the rotation assembly 276 is actuated, i.e., the 45 degree tilted state may include a +45 degree rotated state and a-45 degree rotated state. Further, the portrait screen state includes a +90 degree rotated state and a-90 degree rotated state with respect to the landscape screen state.

S2: and if the display is in the standard state, controlling the display to display the starting-up animation corresponding to the standard state.

Upon detecting the current rotational state of the display 275, the controller 250 may control the display of a power-on animation according to the detected rotational state. When the display 275 is in the normal state, i.e., the display 275 is in the landscape state or the portrait state, the display 275 is controlled to display the corresponding power-on animation.

That is, as shown in fig. 8, in one implementation, if the display is in a standard state, the controller is further configured to:

s211: if the display is in a cross screen state, controlling the display to display a cross screen starting animation;

s212: and if the display is in a vertical screen state, controlling the display to display vertical screen starting animation.

Wherein the landscape screen boot animation is different from the portrait screen boot animation. In the landscape state, the size of the boot animation displayed matches the display scale of the display 275 in the landscape state, and the type of the boot animation also matches the landscape media asset currently being played in the landscape state of the display 275. For example, when the display 275 is in the landscape state, the display 275 has a display screen aspect ratio of 16:9, the controller 250 controls the display 275 to display an aspect ratio also of 16: and 9, the trailer of the movie or the television play is used as the starting animation. Similarly, in the vertical screen state, the aspect ratio of the display screen of the display 275 is 9:16, the controller 250 controls the display 275 to display an aspect ratio also of 9:16 as a power-on animation.

S3: and if the display is in a non-standard state, controlling the rotating assembly to rotate the display to a standard state, and controlling the display to display the boot animation corresponding to the standard state after the display is rotated to the standard state.

When the display 275 is in the non-standard state, as shown in fig. 9, the controller 250 may send a command to the rotating component 276, so that the rotating component 276 may rotate the display 275, rotate the display 275 to a standard state, and control the display 275 to display a power-on animation corresponding to the standard state after the display 275 is rotated to the standard state.

For example, when the controller 250 detects that the rotation angle of the rotating assembly 276 is +30 degrees (30 degrees clockwise with respect to the landscape state), it determines that the rotating state of the display 275 is the non-standard state, and at this time, the rotating assembly 276 may be controlled to rotate the display 275 by-30 degrees (30 degrees counterclockwise) to place the display 275 in the landscape state. After the display 275 is adjusted to the landscape state, the aspect ratio is also displayed in the display 275 as 16:9 movie, movie trailer, and so on.

As can be seen, when the display device 200 of the present application is powered on, the controller 250 may determine the rotation state of the display 275, and display different power-on animations according to the rotation state. When the display 275 is in the landscape state, displaying a boot animation that is appropriate for the landscape state; when the display 275 is a vertical screen, displaying a boot animation that is appropriate for the vertical screen state; when the display 275 is in the non-standard state, the display 275 may be rotated to the standard state first, and then the corresponding boot animation is displayed, so that the user may feel that the boot image and the posture of the display 275 are always matched, thereby improving the user experience.

In the above embodiment, if the display 275 is in the non-standard state, the display 275 needs to be rotated to the standard state first, however, the standard state includes but is not limited to two or more states of the landscape state and the portrait state, and therefore, it is necessary to determine which standard state the display 275 is adjusted to in the process of rotating the display 275 to the standard state. For example, a landscape state of the display 275 may be defaulted as an initial state, and when the display 275 is detected to be in a non-standard state at power-on, the display 275 may be rotated to the landscape state by the rotation component 276 to display a corresponding power-on animation in the landscape state.

In one implementation, rotation of rotating assembly 276 is stopped due to a sudden power failure or malfunction of display 275 when in a non-standard state, typically when the user switches between landscape and portrait screen states. Therefore, it is possible to determine the state in which the display 275 needs to be turned according to the rotation intention at the last time of switching the landscape state and the portrait state, that is, as shown in fig. 10, if the display 275 is in the non-standard state, the controller is further configured to:

s311: rotational intent data is acquired.

The rotation intention data is a rotation state adjustment instruction recorded when the display apparatus 200 was last turned off. The rotation intention data may be recorded by a buffer built in the display device 200, and may be specifically a rotation state adjustment instruction stored in the buffer. The rotation state adjustment command is a command for controlling the rotation of the rotating component 276, and may be manually initiated by the user through the control device 100, or may be automatically generated by the controller 250 according to the screen display state. The rotation intention data may also be obtained from the drive motor of the rotating assembly 276, for example, by obtaining the rotated angle of the motor end and the angle to be rotated, to determine the user's rotation intention.

S312: controlling the rotation component to rotate the display to a standard state specified in the rotation intent data.

After obtaining the rotation intention data, the controller 250 may read the state to which the rotating assembly 276 is to be rotated in the rotation intention data, thereby continuing to control the rotating assembly 276 to rotate according to the current rotation condition of the rotating assembly until the display 275 is rotated to the state that was desired before.

That is, as shown in fig. 11, in one implementation of the present embodiment, the controller 250 is further configured to:

s3121: and extracting an original state and a target state corresponding to the rotation state adjusting instruction from the rotation intention data.

S3122: determining a rotation direction according to the original state and the target state;

s3123: acquiring current corner data of the rotating assembly;

s3124: generating a rotation angle;

s3125: and controlling the rotating assembly to start rotating according to the rotating angle and the rotating direction.

In order to control the rotation component 276 to rotate the display 275 to the standard state specified in the rotation intention data, in this embodiment, the controller 250 may first extract the information in the rotation intention data, and determine the corresponding original state and target state in the last rotation adjustment process of the user. Obviously, the original state and the target state are two different standard states, for example, the original state and the target state are respectively the landscape state and the portrait state, i.e., the last rotation state adjustment instruction corresponding to the user is to adjust the display 275 from the landscape state to the portrait state.

Further, if the standard state of the display 275 of the display device 200 is various, it is necessary to further determine the original state and the target state. For example, when the user last rotates the state adjustment instruction to adjust the display 275 clockwise from the landscape state to the portrait state, the original state and the target state are the landscape state and the + 90-degree portrait state, respectively.

After the adjusted initial state and target state are determined, the direction in which the rotating assembly 276 needs to be rotated, i.e., the rotating direction, can be determined according to the corresponding positional relationship between the initial state and the target state. At the same time, the controller 250 may also extract the current rotational angle data of the rotating assembly 276, i.e., the angle that the rotating assembly 276 has rotated during the last rotation. The rotation angle of the rotating assembly 276 is determined based on the calculated angle difference between the current rotation angle data and the target state, and the rotating assembly 276 is controlled to start rotating according to the rotation angle and the rotation direction.

For example, the display 275 is currently at a +30 degree angle, i.e., in a non-standard state. The controller 250 needs to acquire the rotation intention data, and the controller 250 acquires the recorded rotation state adjustment instruction from the buffer of the display device 200 to rotate the display 275 clockwise from the landscape screen state to the portrait screen state, at this time, it may be determined that the original state of the display 275 is the landscape screen state, the target state is the portrait screen state, and the rotation angle is +90 degrees in the last rotation process. Accordingly, a control command may be sent to the swivel assembly 276 instructing the swivel assembly 276 to rotate 60 degrees clockwise to place the display 275 in a portrait position.

In the above scheme, after the display device 200 is powered on and started, the controller 250 may detect the rotation state of the display 275, when the display 275 is in the non-standard state, the rotation intention of the previous operation of the user may be first determined according to the rotation intention data recorded by the display device 200, and then the display 275 is rotated to the standard state corresponding to the rotation intention, and then the corresponding power-on animation is displayed according to the rotated standard state, so that the power-on animation and the posture of the display 275 are kept consistent, and the user experience is improved.

However, in some cases, the rotation intention data corresponding to the last rotation process may not be recorded in the buffer of the display apparatus 200, for example, the data stored in the buffer is lost or damaged due to power failure or other failures. Or the non-standard state of the display 275 is not caused by a rotation operation, such as manually rotating the display 275 in the off state, causing the display 275 to be in a tilted state. In these cases, the controller 250 will not be able to retrieve the recorded rotation intention data from the buffer of the display device, but the display 275 is also in a non-standard state after power-on start-up, and therefore, as shown in fig. 12, if the rotation intention data is not retrieved, the controller is further configured to:

s321: acquiring current corner data of the rotating assembly;

in practical applications, if the rotation intention data cannot be acquired from the buffer of the display apparatus 200, the controller 250 directly acquires the current rotation angle data of the rotating assembly 276, i.e., detects how much the rotating assembly 276 rotates with respect to the 0-bit angle. For example, when the rotating assembly 276 is in a 0-bit position in the landscape state of the display 275, and after the power-on is started, the controller 250 detects that the rotating assembly 276 rotates clockwise by 65 degrees relative to the 0-bit position, the current rotation angle data is +65 degrees.

S322: determining a proximity state;

after acquiring the current rotation angle data of the rotating member 276, a standard state having the smallest angle difference from the current rotation angle data may be determined as the proximity state. For example, the current rotation angle data is +65 degrees, and the standard state of the display 275 includes: a horizontal screen state (0 degrees), a +90 degrees vertical screen state, and a-90 degrees vertical screen state. Wherein, the angle difference between the horizontal screen state and the current corner data is 60 degrees; the angle difference between the + 90-degree vertical screen state and the current corner data is 25 degrees; the angle difference between the 90-degree vertical screen state and the current rotation angle data is 155 degrees. As can be seen, the standard state with the smallest angle difference from the current corner data is the + 90-degree vertical screen state, and therefore the proximity state is determined to be the + 90-degree vertical screen state.

S323: and controlling the rotating assembly to rotate the display to the adjacent state.

After determining the proximity status, the controller 250 may generate a control signal according to an angle by which the proximity status differs from the current rotation angle data, and transmit the control signal to the driving motor of the rotating assembly 276 to control the rotating assembly 276 to rotate the display 275 to the proximity status. For example, if the current rotation angle data is +65 degrees, the proximity status is +90 degrees vertical screen status, and the angle difference between the proximity status and the current rotation angle data is 25 degrees, the controller 250 generates a control signal indicating that the rotating assembly 276 rotates the display 275 clockwise by 25 degrees, and sends the control signal to the rotating assembly 276 to start rotating.

It should be noted that, in the process of controlling the rotating assembly 276 to rotate the display 275 to the adjacent state, the rotating direction of the rotating assembly 276 may also be determined according to the position relationship between the current rotation angle data and the adjacent state, so that the rotating assembly 276 can rotate the display 275 to the adjacent state as soon as possible. For example, if the current rotation angle data is 23 degrees and the approaching state is the landscape state, it needs to rotate 23 degrees counterclockwise to rotate the display 275 to the landscape state, so the controller 250 generates a control signal indicating that the rotating assembly 276 drives the display 275 to rotate 23 degrees clockwise, and sends the control signal to the rotating assembly 276 to start rotating.

In one implementation, the display device 200 further includes an acceleration sensor; the acceleration sensor is connected to the controller 250. As shown in fig. 13, in response to the activation of the display device 200, the controller 250 is further configured to:

s101: controlling a display to display a logo picture;

s102: and detecting the current rotation state of the display through an acceleration sensor within the time of displaying the sign picture.

The logo image is the first image displayed by the display 275 after the display device 200 is powered on, and may include a logo pattern of the brand of the display device 200. As shown in fig. 9, in order to adapt to various rotation states, the logo screen may be as concise as possible, for example, the periphery is pure color, and logo patterns are only displayed in the middle area. Moreover, the logo pattern displayed in the middle can keep basically consistent picture effect in different rotation states, so that the effect of full display of the picture is provided for the client in visual perception.

The controller 250 may also detect the current rotation state of the display 275 through the acceleration sensor as the control system program is started during the time that the logo screen is displayed. The acceleration sensor may sense the direction of gravity and thereby determine the current pose of the display 275. For example, if the acceleration sensor detects that the deviation angle between the gravity direction and the short side of the display 275 is 30 degrees, it is determined that the current display 275 is rotated clockwise by 30 degrees with respect to the initial landscape state, that is, the current display 275 is in a non-standard state, and needs to be adjusted, for example, after the current display 275 is rotated clockwise by 60 degrees or rotated counterclockwise by 30 degrees, the display 275 is in a standard state, and then the boot animation is displayed.

As can be seen, in this embodiment, a certain time may be reserved for the controller 250 to detect the rotation state and generate the corresponding control instruction by displaying the logo image, so that the display device 200 has a certain transition from the black screen during the startup to displaying the startup animation. In addition, the display duration of the logo image may be fixed, or may be dynamically adjusted according to the program execution condition of the controller 250, that is, in the process of the controller 250 determining the rotation state and determining the played boot animation program, the display 275 displays the logo image until the boot animation is played.

In one implementation, as shown in fig. 14, after the step of controlling the display to display the power-on animation corresponding to the standard state, the controller is further configured to:

s401: sending a homepage data request corresponding to the standard state of the current display to a server;

s402: receiving homepage data fed back by the server in response to the homepage data request;

s403: and controlling the display to display the homepage according to the homepage data.

After the display 275 displays the boot animation, the start-up procedure of the operating system is basically executed, and at this time, a UI interface needs to be displayed on the display 275, so that the user can perform an interactive operation and normally view the movie. Since the display 275 may be in multiple rotated states, different home pages may be presented for the UI interface. In the landscape state, a landscape home page corresponding to the landscape state should be displayed on the display 275. For example, as shown in fig. 15, the control interface is displayed in a form of a landscape screen, and the movie assets displayed on the page may also be movie, tv series, or other landscape assets. Similarly, in the vertical screen state, a vertical screen homepage corresponding to the vertical screen state is displayed on the display 275, for example, as shown in fig. 16, the control interface is displayed in the form of a vertical screen, and the movie resources displayed on the page are also displayed in the form of a short video, a cartoon, and other vertical screen media resources.

To accommodate different rotational states of the display 275, during (or after) the playback of the power-on animation, the controller 250 needs to send a request to the server 300 for home page data corresponding to the current state of the display 275. After receiving the homepage data request again, the server 300 may feed the homepage data back to the display device 200 according to the rotation state designated in the request. The homepage data may include a media asset page and a link file displayed in the homepage, and may further include data such as an arrangement mode of homepage display contents.

After receiving the homepage data fed back by the server 300 in response to the homepage data request, the controller 250 may further perform parsing on the homepage data to merge the homepage data with the corresponding UI interface, so as to control the display 275 to display the corresponding homepage according to the homepage data. For example, when the display device 200 is started, it detects that the display 275 is currently in the landscape state, requests an interface of the server 300 to be called, and sends a request for acquiring the landscape home page data to the server 300. The server 300 responds to the acquisition request and issues the landscape home page data to the controller 250. The controller 250 recognizes the landscape home page data and controls the display 275 to display the landscape home page according to the landscape home page data.

To play the power-on animation in accordance with the rotational state of the display 275, a power-on animation resource file may be stored in the memory 260 of the display device 200. However, in order to reduce the occupation of the storage resources, the memory 260 of the display device 200 cannot store more boot animation resources, so in some cases, the boot animation resources corresponding to some rotation states cannot be acquired from the memory 260 of the display device 200. Thus, in one implementation, as shown in fig. 17, in the step of controlling the display 275 to display the power-on animation corresponding to the standard state, the controller 250 is further configured to:

s501: calling starting animation resources stored in the display equipment;

s502: if the display equipment does not have the starting-up animation resources adaptive to the current standard state, sending a resource data request corresponding to the standard state of the current display to a server;

s503: receiving starting animation resources fed back by the server in response to the resource data request;

s504: and controlling the display to display the boot animation resources.

After determining the rotation state of the display 275, the controller 250 may call up a power-on animation resource in the memory of the display device 200 that is appropriate for the rotation state. For example, at power-on start-up, the display 275 is in a landscape state, and the controller 250 needs to call up a landscape-style power-on animation resource from the memory of the display device 200 to play in the display 275.

But if the power-on animation resource adapted to the current standard state is not acquired from the memory 260 of the display apparatus 200, a resource data request may be sent to the server 300 to acquire the power-on animation resource. For example, when the display 275 is in the vertical screen state at the time of startup, and the memory 260 of the display device 200 does not store the vertical screen startup animation resource, at this time, the controller 250 may send a resource data request to the server 300 to request to obtain the vertical screen startup animation resource data. The server 300, upon receiving the resource data request, may feed back the boot animation resource to the display device 200 in response to the resource data request. The controller 250, upon receiving the fed back boot animation resource, may decode the boot animation resource, thereby controlling the display 275 to display the boot animation resource.

As can be seen, in this embodiment, it is not necessary to store more boot animation resource files in the memory 260 of the display device 200, and the occupation of the storage space of the display device 200 is reduced. Meanwhile, the starting-up animation has short time and the volume of the resource data packet is relatively small, so that the starting-up animation resource can be obtained without waiting for a long time by a user, the starting-up animation played each time is not repeated, and the user experience is improved.

Based on the display device 200, the present application further provides a boot animation display method, as shown in fig. 7, including the following steps:

s1: detecting a current rotation state of the display in response to activation of a display device;

s2: if the display is in the standard state, controlling the display to display the starting-up animation corresponding to the standard state;

According to the above technical solution, the controller 250 of the display device 200 may detect the current rotation state of the display 275 in response to the start-up of the display device 200; if the display 275 is in the standard state, controlling the display 275 to display a boot animation corresponding to the standard state; if the display 275 is in the non-standard state, the control rotation assembly 276 rotates the display 275 to the standard state, and after the display 275 rotates to the standard state, controls the display 275 to display a power-on animation corresponding to the standard state. The display device 200 may display the boot animation corresponding to the rotation state on the display 275 according to the rotation state of the display 275, thereby improving the viewing experience of the user.

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. Any other embodiments extended according to the scheme of the present application without inventive efforts will be within the scope of protection of the present application for a person skilled in the art.
