Description

Display device

Technical Field

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

Background

The smart television 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 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. 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

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The rotary television is a novel intelligent television and mainly comprises a display and a rotary component. Wherein, the display passes through rotatory subassembly to be connected on support or wall, and the angle is placed to the adjustable display of accessible rotatory subassembly, reaches rotatory purpose. Different display placement angles may accommodate animated pages of different aspect ratios, for example, in most cases the display is placed sideways to display video pages of movies, television shows, etc. having an aspect ratio of 16: 9. When a video page is a 9:16 aspect ratio page of short video, caricature, etc., the horizontally positioned display needs to zoom the page and display black areas on both sides of the display. Thus, the display can be positioned vertically by rotating the assembly to accommodate a 9:16 ratio video page.

The applications supported by the rotary television are numerous, so that a user can conveniently watch the television, and a starting signal source of the television can be appointed by setting a starting mode. For example, in order to obtain the viewing experience of a conventional television, a starting signal source of the television may be set as a live broadcast signal, so that the television directly enters a live broadcast state after being started. The user can set the starting signal source into any application program through the setting program. Because the display postures supported by different applications are different, the posture of the television at the time of starting up is adaptive to the application used as the starting-up signal source, and the page corresponding to the application of the starting-up signal source can be normally displayed.

However, when watching tv, the user can adjust the display posture of the rotating tv as required, and still keep the adjusted posture when turning off. For example, when a user watches a short video or a cartoon through a television, the user switches the screen to a vertically placed state and turns off the television in the vertically placed state. When the user starts the computer for the next time, the screen is in a vertically placed state, and if the starting signal source is set to be an application only supporting the horizontally placed state, the screen is not matched with the application of the starting signal source, and the screen cannot be correctly displayed. Therefore, the application provides a display device and a display method of an application interface.

In order to facilitate a user to display a target media asset detail page in different horizontal and vertical screen display directions of a display and to improve the viewing experience of the user of a display device in different viewing states, embodiments of the present application provide a display device, a detail page display method, and a computer storage medium, where the display device is, for example, a rotating television.

In some embodiments, memory 260 specifically stores software and/or programs representing an Operating System (OS), which may include, for example: a kernel, middleware, an Application Programming Interface (API), and/or an application program. Illustratively, the kernel may control or manage system resources, as well as functions implemented by other programs (e.g., middleware, APIs, or applications); at the same time, the kernel may provide an interface to allow middleware, APIs, or applications to access the controller to enable control or management of system resources.

A block diagram of the architectural configuration of the operating system in the memory of the display device 200 is illustratively provided in fig. 4. The operating system architecture comprises an application layer, a middleware layer and a kernel layer from top to bottom.

In FIG. 3, user interface 265, receives various user interactions. Specifically, it is used to transmit an input signal of a user to the controller 250 or transmit an output signal from the controller 250 to the user. For example, the remote controller 100A may transmit an input signal input by a user, such as a power switch signal, a channel selection signal, a volume adjustment signal, etc., to the user interface 265, and then the input signal is forwarded 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.

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. The "user interface" is a medium interface for interaction and information exchange between an application program or an operating system and a user, and realizes conversion between an internal form of information and a form acceptable to the user. A common 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.

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.

Since the display device 200 provided by the present application includes the display 275 and the rotating assembly 276, the rotating assembly 276 can rotate the display 275 to make the display 275 have different display orientations. Thus, in one implementation, the display direction may include a landscape display direction and a portrait display direction. Wherein the landscape display orientation is a display orientation 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 display direction is a display direction 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, depending on the installation/placement position of the display device 200, the vertical direction is referred to as substantially vertical in the present application, and the horizontal direction is also referred to as substantially horizontal. The horizontal display direction is mainly used for displaying horizontal media such as a tv drama and a movie as shown in fig. 5A. The mode of operation when the display 275 is in the landscape orientation may be referred to as the landscape viewing mode, and the mode of operation when the display 275 is in the portrait orientation may be referred to as the portrait viewing mode. The controller 250 in the display device 200 is further communicatively connected to the server 300 for invoking an interface of the server 300 to obtain corresponding data. The display 275 in the display device 200 can be driven to rotate by the rotation assembly 276 and used to display a user interface. In practical applications, a user may control a play mode, play contents, and the like of the display apparatus 200 through the control device 100, wherein the play mode includes a landscape viewing mode and a portrait viewing mode.

The vertical screen display direction is mainly used for displaying vertical media such as short videos and cartoons, as shown in fig. 5B. In the vertical screen display direction, the display 275 may display the user interface corresponding to the vertical screen display direction and have an interface layout and an interaction mode corresponding to the vertical screen display direction. In the vertical screen media asset watching mode, a user can watch vertical screen media assets such as short videos and cartoons. Similarly, 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 when the vertical screen displays the direction.

The vertical screen display direction is more suitable for playing the page with the ratio of 9:16, etc., such as short videos shot by a terminal such as a mobile phone, etc. Because terminal equipment such as cell-phones adopts 9 more: 16,9: 18, and the like, when the terminal accesses the display device 200 and displays a terminal page through the display device 200, the vertical screen display direction can avoid excessive zooming of the page, the application page of the display 275 is fully utilized, and better user experience is achieved.

It should be noted that the horizontal screen display direction and the vertical screen display direction are only two different display directions of the display 275, 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 display direction; horizontal media such as TV dramas and movies can still be displayed in the vertical screen display direction, and only the display windows which are not matched with each other need to be compressed and adjusted in the display direction.

When the user uses the display device 200, the display direction of the display 275 is adjusted according to the user's viewing requirements. For example, after a rotation command is issued by controlling a rotation key on the apparatus 100, or selecting a rotation option on a UI interface, or inputting a "rotation" related voice through a voice system, the controller 250 controls the rotation component 276 to rotate according to the rotation command to drive the display 275 to rotate. For example, when a user wants to watch a short video through the display device 200, the user can input a rotation instruction in one of the above manners to rotate the display 275 in the landscape display direction counterclockwise by 90 degrees to the portrait display direction, so as to adapt to the page scale of a vertical application such as a short video.

The current display device generally performs posture monitoring based on a monitoring component. Each application needs to read the rotation data monitored by the monitoring component in real time, when the posture of the television changes, the corresponding monitoring number changes, and each application respectively carries out corresponding processing on the read rotation data. This kind of mode on the one hand needs to use and monitors the monitoring subassembly always, leads to data processing volume too big, occupies too much system resource, and on the other hand when an APP goes the rotatory display voluntarily, whether the rotation has really taken place for remaining APP to judge the TV by oneself through gravity sensor's data, and the judgement mode between each is used is inconsistent, and the data also share can know the processing logic inconsistency of every application, can lead to the cooperation to appear unusually.

In order to solve the technical problem in the prior art, a first aspect of the embodiments of the present application shows a display device, specifically, referring to fig. 6, fig. 6 is a structural block diagram of a display device according to a feasible embodiment, and it can be seen that the display device at least includes: a display 275; a rotating component 276 connected with the display, wherein the rotation can drive the display to switch between a horizontal screen mode and a vertical screen mode; and a controller 250 for controlling the operation of the display device and responding to the user's operation by operating various software control programs (e.g., an operating system and various application programs) stored in the memory 260. The operating system architecture comprises an application layer, a framework layer, a middleware layer and a kernel layer from top to bottom.

Operation flow diagram of a display device referring to fig. 7, 7 is a flowchart illustrating operation of a display device according to a possible embodiment.

In response to the rotation instruction, the first application executes step S101 to control the rotation of the rotation member.

In the present application, the first application is an application that receives a rotation instruction; for example, the application layer is installed with 6 applications, which are application 1, application 2, application 3, application 4, application 5, and application 6. The 6 applications may run on the display device simultaneously or partially. At a certain time, application 1 receives the rotation instruction, and application 1 is the first application. Applications other than the first application may be referred to as a second application in this embodiment.

In the technical solution shown in the embodiment of the present application, the rotation instruction may be issued by a user, for example, in a feasible embodiment, the user needs to control the display to rotate, and the user may issue the rotation instruction through voice or remote control. The rotation instruction may also be actively generated by the first application, for example, in a feasible embodiment, the application 1 determines that the display direction of the display does not match with the application interface of the application 1, and the application 1 may actively generate the rotation instruction. It should be noted that the present embodiment only shows several ways of generating the rotation command by way of example, and the ways of generating the rotation command in the process of practical application may be, but are not limited to, the above-mentioned ways.

In response to the rotating component starting to rotate, the frame layer is configured to perform steps S102 and S103;

s102, sending a start broadcast; step S103, reading the rotation state of the display to obtain rotation data;

the framework layer is configured to perform step S104 of converting the rotation data into a rotation angle according to a preset rule; s105, storing the rotation angle;

there are various ways to convert the rotation data into the rotation angle according to the preset rule.

For example, in a possible embodiment, the rotation data may include: angular acceleration; the process of generating the rotation angle of the frame layer can be seen in fig. 8.

The frame layer is further configured to perform steps S411 to S413;

in response to the rotating assembly starting to rotate, executing step S411 to read N angular accelerations according to a first preset frequency;

in this embodiment, the purpose of reading the N angular accelerations by the controller is to calculate the angular velocity of the display during the rotation. The shorter the time taken to generate the angular velocity of rotation, the more advantageous the subsequent process, and therefore, a larger first preset frequency, for example, 1ms, may be used in this embodiment to read an angular acceleration.

The number N of angular accelerations is not limited in this embodiment, and may be equal to 10 in a feasible real-time, for example.

In a possible embodiment, in order to reduce the data processing amount of the frame layer, the frame layer may terminate reading the angular acceleration after acquiring the N angular accelerations.

S412, calculating a rotation angular velocity according to the N angular accelerations, wherein the rotation angular velocity is an angle rotated by the display in unit time;

for example, in a possible embodiment, the first preset frequency is 1 ms/time, and N is 10. The frame layer responds to the start broadcast, and the reading angular acceleration according to the sampling frequency of 1 ms/time is respectively as follows: a1, a2, a3, a4, a5, a6, a7, a8, a9, a 10; the frame layer calculates a rotation angular velocity V according to the following formula;

v ═ V (a1+ a2+ a3+ a4+ a5+ a6+ a7+ a8+ a9+ a10)/Ti, where Ti is the time taken to acquire N addition numbers.

S413 calculates the rotation angle β from the rotation angular velocity.

The frame layer calculates a rotation angle beta according to the following formula;

β ═ V × Tj, where Tj is the time from the receipt of the start broadcast to the calculation of the rotation angle.

For another example, in a possible embodiment, the rotation data may include: an initial angle and an angular acceleration; process of generating the rotation angle of the frame layer referring to fig. 9, the frame layer is further configured to perform steps S421 to S422;

s421, responding to the starting rotation of the rotating assembly, reading an initial angle once, and collecting angular acceleration according to a second preset frequency;

in this embodiment, the framework layer only reads an initial angle when a start broadcast is received.

The second preset frequency can be set according to requirements, and the frame layer continuously collects the angular speed until the display stops rotating. For example, in a possible embodiment the second preset frequency may be 20 ms/time.

S422, the rotation angle is calculated according to the initial angle and the angular acceleration.

For example, in a possible embodiment, the second preset frequency is 20 ms/time. The gantry layer starts to rotate in response to the rotating assembly, reading an initial angle of 90 degrees, the gantry layer reading one ai every 20 ms. β 1 ═ 90+ a1, β 2 ═ β 1+ a2, β 3 ═ β 2+ a3 … … β n ═ β n-1+ an until the display ceases to rotate.

It should be noted that the present embodiment is only an exemplary implementation manner showing two rotation angle calculation manners, and in the process of practical application, the implementation manner of calculating the rotation angle may be, but is not limited to, the two manners described above.

In a feasible embodiment, the rotation angle may be stored in the RAM, and each time the rotation is completed, the rotation angle generated in the current rotation process is released to reduce the data storage amount of the display device.

Among them, there are various implementations in which the rotation angle is transmitted between the frame layer and the application layer.

For example, fig. 7 shows an implementation in which the application actively reads the rotation angle to the frame layer in response to starting the broadcast, executing step S106.

It should be noted that the present embodiment merely describes two implementation manners of transferring the rotation angle between the frame layer and the application layer by way of example, and in the process of practical application, the implementation manner of transferring the rotation angle between the frame layer and the application layer may be, but is not limited to, the above two implementation manners.

The application performs step S107 to draw the presentation page based on the rotation angle. So that the presentation direction of the presentation page always matches the viewing direction of the user. FIG. 10 is a schematic diagram illustrating the change of the display presentation page during rotation according to one possible embodiment

The display executes step S108 to display a presentation page.

As can be seen from fig. 10, the presentation direction of the presentation page always matches the viewing direction of the user.

Since the display device can pull up a plurality of applications at the same time, in order to avoid mutual interference between the applications, the embodiment of the present application illustrates a display device, and the operation flow of the display device may refer to fig. 11, where fig. 11 is an operation flow diagram of the display device according to a feasible embodiment, and the function of the application may refer to the above embodiment. The frame layer is further configured to perform steps S31-S33.

In response to the rotation component starting to rotate, step S31 is executed to call the rotation interface to read the rotation state of the display to obtain rotation data.

The rotation data in this embodiment may include: status information and rotation information; wherein the state information may include: rotation information and termination information;

in this embodiment, the controller generates different status information according to the status of the display. The rotation information is generated when the display is in a rotated state, and the termination information is generated when the display is in a terminated state.

The controller determining whether the display is in the rotated state or the terminated state may be, but is not limited to: the angle of rotation (angular acceleration) of the display per unit time is a function.

For example, the controller may preset an angular acceleration threshold a, and when the monitored angular acceleration is greater than or equal to a, the display is in a rotating state; when the monitored angular acceleration is less than a, the display is in a rotated state. In practice, the controller may determine whether the display is in the rotation state or the rotation termination state in other manners.

In response to reading the rotation information, executing step S104 to convert the rotation information into a rotation angle according to a preset rule;

the rotation angle conversion process can refer to the above embodiments, and is not described herein.

In response to reading the termination information, step S32 is executed to release the rotary interface.

In the application, the rotary interface cannot be called repeatedly in the using process.

In response to the rotating component starting to rotate, the framework layer is configured to call the rotating interface to read the rotating state of the display to obtain rotating data. In response to reading the termination information, the framework layer releases the rotary interface, which cannot be recalled during use. Because the rotary interface can not be called repeatedly in the using process, the framework layer can be controlled only based on one application at the same time, and the display equipment can avoid mutual interference among different applications.

For example, the following steps are carried out: in a possible embodiment, the display device simultaneously installs 4 applications: application 1, application 2, application 3, and application 4. At 10 o' clock 35 min 0 sec, application 1 receives a rotation command 1, and application 1 sends a start broadcast. The framework layer invokes the spin interface to read spin data (including termination status, spin information) of the spin component in response to initiating the broadcast. When the rotation state is read, the framework layer converts the rotation information into a rotation angle and sends the rotation angle in a broadcast mode, so that the application can draw the display page based on the rotation angle. At 10 o' clock 35 min 3 sec, application 2 generates rotation instruction 2. In response to the rotation instruction 2, the application 2 transmits a start broadcast. At this time, the framework layer may receive the start-up broadcast, but the rotary interface cannot be called repeatedly during use, and thus the framework layer ignores the start-up broadcast received a second time.

In a feasible embodiment, the second application may be configured to: the rotation command is not responded to during a period from the reception of the start broadcast to the reception of the termination broadcast.

Alternatively, to prevent the display from rotating to the end, the application continues to read the stored rotation angle in the frame layer. In a possible embodiment, in response to reading the termination information, the framework layer is further configured to perform step S1052 of sending the termination broadcast. In response to terminating the broadcast, the application terminates reading the rotation angle.

Alternatively, to prevent the display from rotating to the end, the application continues to read the stored rotation angle in the frame layer. In a possible embodiment, the frame layer terminates the broadcast rotation angle in response to reading the termination information.

Alternatively, in a possible embodiment, the termination information may include: first termination information and second termination information. The first termination information is generated when the controller monitors that the display rotates to a preset angle, and the second termination information is generated when the controller monitors that the display does not rotate to the preset angle.

Typically, the first application controls the display to switch between landscape and portrait states. Correspondingly, the preset angle is reached when the display rotates 90 degrees each time, and the controller monitors first termination information generated when the display rotates to the preset angle. The display is in the rotatory in-process, probably receives the position restriction or receives the restriction of rotating assembly and subassembly structure thereof, rotates certain angle to certain direction after, just can not continue to rotate to this direction again, and the angle of display rotation can not reach 90 degrees this moment, and the controller monitors the second that the display produced when not rotating preset angle and terminates the information in this application.

In this application, the rotation data that the frame layer read still includes: the direction of rotation. And when the frame layer reads the second termination information, the frame layer releases the rotary interface and simultaneously enables the current rotation angle and rotation direction of the display to be displayed. After that, in response to receiving the rotation instruction, the first application controls the reverse rotation of the display to the rotation direction.

For example, in one possible embodiment, the display device simultaneously installs 4 applications, application 1, application 2, application 3, and application 4. 10 o' clock 35 min 0 sec, application 1 receives rotation instruction 1, and application 1 transmits a start broadcast. The framework layer invokes the rotation interface to read rotation data (including termination status, rotation information, rotation direction) of the rotating component in response to initiating the broadcast. When the rotation state is read, the frame layer converts the rotation information into a rotation angle and sends the rotation angle in a broadcast mode. And when the time is 10 o' clock and 35 min/3 sec, the frame layer reads second termination information (the rotation angle is 45 degrees at this time), and sends a termination broadcast, wherein the termination broadcast comprises that the rotation direction rotates anticlockwise and the rotation angle is 45 degrees. At 10 o' clock 36 min 3 sec, application 2 generates rotation instruction 2. In response to rotation instruction 2 (rotation instruction 2 controls the display to rotate to the landscape display orientation), application 2 controls the display to rotate 45 degrees clockwise.

In a possible embodiment, the display device installs 4 applications simultaneously, application 1, application 2, application 3 and application 4 respectively. 10 o' clock 35 min 0 sec, application 1 receives rotation instruction 1, and application 1 transmits a start broadcast. The framework layer invokes the rotation interface to read rotation data (including termination status, rotation information, rotation direction) of the rotating component in response to initiating the broadcast. When the rotation state is read, the frame layer converts the rotation information into a rotation angle and transmits the rotation angle in a broadcast mode. And when the 10-point frame reads 35 minutes and 3 seconds, the frame layer reads second termination information (the rotation angle is 45 degrees in the moment), and sends termination broadcast, wherein the termination broadcast comprises that the rotation direction rotates anticlockwise and the rotation angle is 45 degrees. At 10 o' clock 36 min 3 sec, application 2 generates rotation command 2. In response to rotation instruction 2 (rotation instruction 2 controls the display to rotate to the vertical screen display direction), application 2 controls the display to rotate clockwise (45+90) degrees.

It can be seen that the present embodiment shows a technical solution, in a case where the second termination information broadcasted by the frame layer is received, in response to receiving the rotation instruction, the first application controls the reverse rotation of the display to the rotation direction to prevent the rotation component from being excessively rotated.

Optionally, in a possible embodiment, the frame layer is further configured to: real-time statistical rotation time, starting from the time the start broadcast is received. If the rotation time is equal to the preset time, the transmission terminates the broadcast.

A second aspect of the embodiments of the present application shows a display device, and a schematic structural diagram of the display device may continue to refer to fig. 6. Operation flow diagram of a display device referring to fig. 12, fig. 12 is a flowchart illustrating an operation of a display device according to a possible embodiment.

The display device shown in the embodiment of the application comprises a display, a rotating assembly and a controller, wherein the controller is used for running an application layer and a framework layer; the application layer is provided with a plurality of applications.
