Description

Display device and picture display method

Technical Field

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

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 resources 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 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 smart television is generally in a horizontal state of 16:9, 16:10 and the like, so when vertical resources such as short videos, cartoons and the like are displayed through the smart television, vertical resource pictures cannot be normally displayed due to the fact that the picture proportion is not matched with the display screen proportion. Generally, the vertical resource pictures 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 social television is a novel intelligent television and mainly comprises a display and a rotary component. The display is connected to the support or the wall through the rotating assembly, and the display placing angle can be adjusted through the rotating assembly to achieve the purpose of rotation. Different display placement angles may accommodate different aspect ratio displays, for example, in most cases the displays are placed horizontally to display 16:9 aspect ratio movies, television shows, and other video images. When a video frame has a 9:16 aspect ratio of short video, caricature, or the like, the horizontally disposed display needs to be scaled and black areas are displayed on both sides of the display. Thus, the display can be positioned vertically by rotating the assembly to accommodate a 9:16 scaled video frame.

The applications supported by the rotary social 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 can be set as a live signal, so that the television directly enters a live state after being started. The user can set the starting signal source into any application program through the setting program. Because the postures of the display 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 picture corresponding to the application of the starting-up signal source can be normally displayed.

However, when watching television, the user can adjust the display posture of the rotary social television according to needs, and the display posture is still kept after adjustment when the television is turned 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 picture display method.

In order to facilitate a user to display a target resource detail page in different horizontal and vertical screen states of a display and to improve the user viewing experience 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.

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. Because the display device 200 provided herein includes the display 275 and the rotating assembly 276, the rotating assembly 276 can rotate the display 275 to enable the display 275 to be in different display orientations. Thus, in one implementation, the display direction may include a landscape display direction and a portrait display direction. Wherein the horizontal display direction is a display direction 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, 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 landscape orientation is mainly used to display landscape assets such as dramas and movies as shown in fig. 5A. The mode of operation of the display 275 in the landscape orientation may be referred to as the landscape asset viewing mode and the mode of operation of the display 275 in the portrait orientation may be referred to as the portrait asset 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 resource viewing mode and a portrait resource viewing mode.

The vertical screen display direction is mainly used for displaying vertical resources 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 resource watching mode, a user can watch vertical screen resources 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, when the vertical screen displays the direction, the interface of the server 300 is called to obtain the resource data corresponding to the vertical screen.

The vertical screen display direction is more suitable for playing the picture with the ratio of 9:16, etc., such as short videos, pictures, etc., taken by a terminal, such as a mobile phone. 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 the terminal screen through the display device 200, the vertical screen display direction can avoid the transition scaling of the screen, the display screen of the display 275 is fully utilized, and better user experience is achieved.

When the user uses the display device 200, the display direction of the display 275 is adjusted according to the user's needs. 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 the user wants to watch a short video through the display device 200, the user may input a rotation instruction in one of the above manners to rotate the display 275 in the landscape display orientation state by 90 degrees counterclockwise to the portrait display orientation, so as to adapt to the picture scale of a vertical application such as a short video.

At present, more and more users connect the mobile terminal 1 with the display device 200, and take pictures of the mobile terminal 1 and project the pictures on the display device 200 for display. The resource shot by the mobile terminal 1 may be a vertically displayed picture or a horizontally displayed picture. For example, pictures taken by the mobile terminal 1 such as a mobile phone are generally vertical display pictures with aspect ratios of 9:16, 9:18, 3:4, and the like; in some embodiments, the pictures taken by the mobile terminal 1 may also be landscape pictures with aspect ratios of 16:9, 18:9, 4:3, etc. In an application environment where a picture taken by the mobile terminal 1 is displayed on a display of the display device 200, how to ensure that the picture uploaded by the mobile terminal 1 is adapted to a display direction of the display becomes a technical problem to be solved urgently.

In order to solve the above technical problem, the present application provides a display device 200, as shown in fig. 6, wherein a controller 250 is configured to execute the following program steps:

s101: receiving a picture storage path pushed by the mobile terminal 1;

s102: loading a corresponding picture based on the picture storage path;

when the mobile terminal 1 establishes a communication path with the display device 200, the mobile terminal 1 may communicate with the controller 250 or push a picture.

In a feasible implementation, the pushed picture may be stored in a local memory of the mobile terminal 1, and when the mobile terminal 1 establishes a communication path with the display device 200, the mobile terminal 1 directly pushes the locally stored picture to be pushed to the controller 250.

In a feasible implementation, the pushed picture is stored in the cloud server, the mobile terminal 1 stores a storage path of the picture, where the path is a storage address of the picture in the cloud server, and when the mobile terminal 1 establishes a communication path with the display device 200, the mobile terminal outputs the storage path of the picture to be pushed to the controller 250, so that the controller 250 can call a corresponding picture based on the storage path.

Specifically, the controller 250 requests to call a corresponding interface on the server based on the picture storage path pushed by the mobile terminal 1, so as to perform a data request. After receiving the picture request, the server sends the corresponding picture to the controller 250. The controller 250 stores the picture locally and loads the picture.

After the loading of the picture is completed, the controller 250 may read the picture attribute set by the user by executing the related program, determine the display direction of the picture, and implement various manners for determining the display direction of the picture.

For example, the controller 250 may determine the display direction of the picture by reading the resolution of the picture, which includes the width and height of the picture. If the width is larger than the height, the display direction of the picture is a transverse screen display direction; and if the width is smaller than the height, the display direction of the picture is the vertical screen display direction.

Specifically, after the action of loading the picture is completed, the attribute value of the picture is also stored in the local memory of the controller 250, and at this time, the controller 250 may determine the display direction of the picture by calling the resolution in the attribute value. The resolution describes the number of pixels included in a picture in both the "horizontal" and "vertical" dimensions. For example, a 1920 × 1080 picture is composed of 1920 pixels in the horizontal direction and 1080 pixels in the vertical direction (2,073,600 pixels in total). Based on the resolution, whether the picture is a horizontal screen display picture or a vertical screen display picture can be obtained.

In a possible embodiment, the resolution of the picture loaded by the controller 250 is 320 × 240, and the controller 250 determines that the picture is a landscape display picture. In another possible embodiment, the controller 250 calls 768 × 1024 resolution of the loaded picture, and the controller 250 determines that the picture is a vertical screen display picture.

For another example, the controller 250 may determine the width and height of the picture by reading a header file of the picture; if the width is larger than the height, the display direction of the picture is a transverse screen display direction; and if the width is smaller than the height, the display direction of the picture is the vertical screen display direction.

The technical scheme shown in the embodiment of the application can screen the header files by identifying the identifiers of the header files; then, reading the width and height of the picture loaded in the header file; and finally, determining whether the picture is a horizontal screen display picture or a vertical screen display picture according to the width of the picture and the height of the picture.

There are many formats for pictures downloaded over the network, such as: JPEG, PNG, etc. type pictures. Each type of picture has its corresponding header identification. According to the technical scheme shown in the embodiment of the application, the corresponding relation between the picture format and the header file identifier is established in advance, and then the corresponding relation between the picture format and the header file identifier is stored in the first list. The format of the first list can be seen in table 1.

TABLE 1

Specifically, the method for screening the header file may be: and determining a picture format corresponding to the picture. In practical applications, the controller 250 may determine the picture format of the picture through the suffix of the picture. The controller 250 filters out a header file identifier corresponding to the picture format according to a first list traversed by the picture format, wherein the first list is used for recording a corresponding relationship between the picture format and the header file identifier; controller 250 screens out header files in the picture based on the header file identification.

For example, the controller 250 receives a picture with a suffix of. Determining the picture format of the picture as GIF; the header file identifier corresponding to the GIF is determined to be: 4749. and determining that the picture corresponding to the '4749' is a header file.

The controller 250 is configured to traverse the header file, filter out size information, and send the size information including the width of the picture and the height of the picture.

Specifically, the header file of the picture stores the related information of the picture, and the corresponding field can be read from the header file to obtain the size information such as the size, the format and the like.

Alternatively, the corresponding width and height data bits can be found from the header file of the picture, and the width and height information (i.e. size information) in the header file can be extracted by decoding and analyzing the obtained picture data.

Specifically, the data bits for the aspect information of the picture in each header are fixed. According to the technical scheme shown in the embodiment of the application, the corresponding relation between the head file identification and the data bit of the width and height information is established in advance, and then the corresponding relation between the head file identification and the data bit of the width and height information is stored in the second list. The format of the second list can be seen in table 2.

TABLE 2

Specifically, the controller 250 may traverse a second list according to the header file identifier to determine the size information data bits in the header file, where the second list is used to record the corresponding relationship between the header file identifier and the size information data bits. And calling data corresponding to the size information data bits in the header file, wherein the data is size information.

For example, the controller 250 determines that the header file identifier 424D in the received picture is identified. Going through table 2, the data bits with width and height corresponding to the header file identification "424D" are determined to be wide: 0x0303, high: 0X01B2, calling data corresponding to size information data bits in the header file: the width is: 771, high is: 434.

in a possible embodiment, the controller 250 calls the width of the loaded picture as: 771, high is: 434, the controller 250 determines that the picture is a landscape display picture. In another possible embodiment, the controller 250 calls the width of the loaded picture as: 1024, high is: 956, the controller 250 determines that the picture is a vertical screen display picture.

For another example, the controller 250 is further configured to: reading a direction identifier carried by the picture;

if the direction mark is horizontal, the picture is a horizontal screen display picture, and if the direction mark is vertical, the picture is a horizontal screen display picture. The direction identifier can be added into the header file of the picture: com. H is a first identification value and represents that the corresponding picture is a horizontal screen display picture, and V is a first identification value and represents that the corresponding picture is a vertical screen display picture. The controller 250 through the controller 250 may determine whether the picture is a landscape display picture or a portrait display picture by reading the direction identification value of the picture. In the process of practical application, a first identification value and a second identification value can be set according to requirements. Applicant does not make any undue restrictions herein.

In a possible embodiment, the controller 250 invokes the orientation identification of the loaded picture: com, android, jpg, H, the controller 250 determines that the picture is a landscape picture. In another possible embodiment, the controller 250 invokes the orientation identification of the loaded picture: com, android, jpg, V, the controller 250 determines that the picture is a portrait screen display picture.

While establishing a communication path with the mobile terminal 1, the controller 250 is further configured to acquire a current presentation direction of the display 275. The current presentation direction of the display 275 may be detected by a sensor built into the display device 200. For example, a gyroscope, a gravitational acceleration sensor, or the like is provided on the display 275 of the display device 200, and attitude data of the display 275 with respect to the direction of gravity can be determined by measuring angular acceleration or the direction of gravity. The detected attitude data is then compared with the attitude data in the horizontal screen display direction and the vertical screen display direction, respectively, to determine the display direction in which the display 275 is currently located.

For another example, a grating angle sensor, a magnetic field angle sensor, a sliding resistance angle sensor, or the like may be provided on the rotating member 276, and the display direction in which the display 275 is currently located may be determined by measuring the angle of rotation of the rotating member 276 and comparing the angle with the angle in the landscape display direction and the portrait display direction, respectively.

S103: and if the display direction of the picture is consistent with the display direction of the display 275, controlling the display 275 to display the picture.

S104: and if the display direction of the picture is consistent with the display direction of the display 275, controlling the display 275 to display the picture.

In the actual display adaptation process, if the loaded picture is consistent with the front display direction of the display 275, the loaded picture may be directly displayed. If the loaded picture does not correspond to the previous presentation orientation of the current display 275, the display 275 is rotated such that the presentation orientation of the display 275 corresponds to the presentation orientation of the picture.

For example, if the angle sensor detects that the current rotation angle of the display 275 is 90 degrees, the display direction of the display 275 can be determined to be the vertical screen display direction. When it is determined that the currently loaded picture is a landscape display picture, and thus it is determined that the display direction of the picture is consistent with the display direction of the display 275, the display 275 may be rotated such that the display direction of the display 275 is consistent with the display direction of the picture.

After receiving the picture pushed by the mobile terminal 1, the display device 200 provided in the above embodiment determines whether the picture is a landscape display picture or a portrait display picture, and determines whether to control the display 275 to rotate according to the current display direction of the display 275. In the process of practical application, the pictures stored in the mobile terminal 1 are mostly sorted according to the shooting time sequence, so that the pictures pushed to the display device 200 by the mobile terminal 1 are displayed on a horizontal screen, and are displayed on a vertical screen. Accordingly, the display device 200 needs to frequently rotate the display 275 in order to match the display direction of the picture during the display of the picture. Fig. 7 is an interactive scene diagram of the display device 200 and the mobile terminal 1 shown in a feasible embodiment, and it can be seen that the mobile terminal 1 needs to push 8 pictures to the display device 200, where the shooting time sequence of the 8 pictures corresponds to the numbers in the figure, and correspondingly, the pushing sequence of the 8 pictures is a landscape display picture 1, a landscape display picture 2, a portrait display picture 3, a portrait display picture 4, a landscape display picture 5, a landscape display picture 6, a portrait display picture 7, and a landscape display picture 8. Accordingly, the display device 200 undergoes a total of 4 rotations in the process of displaying the above 8 pictures.
