Description

Display equipment and picture display method

Technical Field

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

Background

The intelligent television has an independent operating system and supports function expansion. Various application programs, such as a traditional video application, a social application such as a short video and the like, and a reading application such as a cartoon and a reading application such as a reading application, can be installed in the intelligent television according to user needs. The applications can utilize the screen of the intelligent television to display application pictures, 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 tv may be connected to the mobile phone through a wireless communication manner such as a local area network, bluetooth, etc., so as to play resources in the mobile phone or directly perform screen projection to display a picture on the mobile phone.

However, since the proportion of pictures corresponding to different applications or resources from different sources is different, smart televisions are often used to display pictures different from the conventional video proportion. For example, video resources photographed by a terminal such as a mobile phone are typically vertical resources with aspect ratios of 9:16, 9:18, 3:4, etc.; while the view provided by the reading application is a vertical resource similar to the aspect ratio of a book. The aspect ratio of the display screen of the smart television is generally in a transverse state of 16:9, 16:10 and the like, so that when the smart television displays vertical resources such as short videos, cartoon and the like, the vertical resource pictures cannot be normally displayed due to the fact that the picture proportion is not matched with the display screen proportion. The vertical resource picture is generally required to be scaled 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 the technical solution of the present application better understood by those skilled in the art, the technical solution of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the 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 bracket or the wall through the rotating assembly, and the placement angle of the display can be adjusted through the rotating assembly, so that the purpose of rotation is achieved. Different display placement angles can accommodate different aspect ratio display pictures, e.g., the display is in most cases placed sideways to display video pictures of movies, television shows, etc. with an aspect ratio of 16:9. When the aspect ratio of the video picture is a short video of 9:16, a cartoon, or the like, the horizontally placed display needs to scale the picture, and black areas are displayed on both sides of the display. Thus, the display can be placed vertically by the rotating assembly to accommodate a 9:16 ratio of video pictures.

The applications supported by the rotary social television are numerous, and in order to facilitate the user to watch, a starting signal source of the television can be specified by setting a starting mode. For example, in order to obtain the viewing experience of the conventional television, a power-on signal source of the television may be set to be a live signal, so that the television directly enters a live state after being powered on. The user can set the power-on signal source as any application program through the setting program. Because the postures of the displays supported by different applications are different, the postures of the television during starting up are matched with the applications serving as starting-up signal sources, so that pictures corresponding to the starting-up signal source applications can be normally displayed.

However, when watching television, the user can adjust the gesture of the display of the rotary social television according to the requirement, and still keep the adjusted gesture when turning off. For example, when a user views a short video or a cartoon through a television, the user switches the screen to a vertically placed state and turns off the screen in the vertically placed state. When the user starts up next time, the gesture of the screen is in a vertical placement state, and if the starting-up signal source is set to be an application only supporting the horizontal placement state, the gesture of the screen is not matched with the starting-up signal source application, and the screen cannot be displayed correctly. 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 facilitate the improvement of user viewing experience of display equipment in different viewing states, the embodiment of the application provides display equipment, a detail page display method and a computer storage medium. It should be noted that, the method provided in this embodiment is not only applicable to a rotary television, but also applicable to other display devices, such as a computer, a tablet computer, and the like.

The power supply 290 is used for providing power supply support for the display device 200 by power input by an external power supply under the control of the controller 250. The power supply 290 may be a built-in power supply circuit mounted inside the display device 200 or may be a power supply mounted outside the display device 200. Because the display device 200 provided by the application comprises the display 275 and the rotating assembly 276, the rotating assembly 276 can drive the display 275 to rotate so as to enable the display 275 to be in different display directions. Thus, in one implementation, the presentation directions may include a landscape presentation direction and a portrait presentation direction. Wherein the horizontal display direction refers to 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 refers to 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, which is affected by the mounting/placement position of the display device 200. The horizontal screen display direction is mainly used for displaying horizontal resources such as television dramas, movies and the like as shown in fig. 5A. The mode of operation of the display 275 in the landscape orientation may be referred to as a landscape resource viewing mode and the mode of operation of the display 275 in the portrait orientation may be referred to as a portrait resource 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 the corresponding data. The display 275 in the display device 200 can be rotated by the rotation assembly 276 and used to display a user interface. In practical applications, the user may control the play mode, play content, etc. of the display apparatus 200 through the control device 100, where the play mode includes a horizontal screen resource viewing mode and a vertical screen resource viewing mode.

The vertical screen display direction is mainly used for displaying vertical resources such as short videos and cartoon pictures, as shown in fig. 5B. In the vertical display direction, the display 275 may display a user interface corresponding to the vertical display direction and possess an interface layout and an interaction manner corresponding to the vertical display direction. In the vertical screen resource viewing mode, a user can view short video, cartoon and other vertical screen resources. Similarly, since the controller 250 in the display device 200 is further communicatively connected to the server 300, when the vertical screen displays directions, the resource data corresponding to the vertical screen can be acquired by calling the interface of the server 300.

The display direction of the vertical screen is more suitable for playing the picture with the proportion of 9:16, etc., for example, short video, pictures, etc., taken by a terminal such as a cell phone. As the terminal equipment such as mobile phones and the like adopts 9:16,9:18, etc., so that when the terminal is connected to the display device 200 and the terminal picture is displayed by the display device 200, the transition scaling of the picture can be avoided by the vertical screen display direction, the display picture of the display 275 is fully utilized, and better user experience is provided.

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 a rotation key on the control device 100, or by selecting a rotation option on the UI interface, or by inputting a "rotation" related voice through the voice system, the controller 250 controls the rotation component 276 to rotate according to the rotation command, so as 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 may input a rotation command in one of the above ways, so that the display 275 in the horizontal display direction state rotates 90 degrees counterclockwise to the vertical display direction, thereby adapting to the screen ratio of the vertical application such as the short video.

At this stage, more and more users connect the mobile terminal 1 with the display device 200, take pictures from the mobile terminal 1, and project the pictures on the display device 200 for display. The resources shot by the mobile terminal 1 can be vertically displayed pictures or horizontally displayed pictures. For example, the pictures taken by the mobile terminal 1 such as a mobile phone are typically vertical display pictures with aspect ratios of 9:16, 9:18, 3:4, etc.; in some embodiments, the pictures taken by the mobile terminal 1 may also be horizontal screen presentation pictures with aspect ratios of 16:9, 18:9, 4:3, etc. In an application environment in which a picture taken by the mobile terminal 1 is displayed through a display of the display device 200, how to ensure that the picture uploaded by the mobile terminal 1 is matched with the display direction of the display is a technical problem to be solved.

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

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

s102: loading corresponding pictures 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 pictures.

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 storage server, the mobile terminal 1 stores a storage path of the picture, the path is a storage address of the picture in the cloud storage 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 the corresponding picture based on the storage path.

The specific invoking process is that the controller 250 invokes the corresponding interface on the server based on the picture storage path request pushed by the mobile terminal 1 to perform the data request. After receiving the picture request, the server issues the corresponding picture to the controller 250. The controller 250 stores the picture locally and loads the picture.

After loading the picture, the controller 250 may determine the display direction of the picture by executing the related program to read the picture attribute set by the user, and various implementations of determining the display direction of the picture are available.

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 horizontal screen display direction; and if the width is smaller than the height, the display direction of the picture is a 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 retrieving the resolution in the attribute value. The resolution describes the number of pixels that the picture contains in both the "horizontal" and "vertical" dimensions. For example, 1920×1080 pictures are constituted by 1920 pixels in the horizontal direction and 1080 pixels in the vertical direction (total 2,073,600 pixels). Based on the resolution, whether the picture is a horizontal screen display picture or a vertical screen display picture can be known.

In a feasible embodiment, the resolution of the picture loaded by the controller 250 is 320×240, and then the controller 250 determines that the picture is a landscape picture. In another possible embodiment, when the resolution of the loaded picture is 768×1024, the controller 250 determines that the picture is a vertical 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 horizontal screen display direction; and if the width is smaller than the height, the display direction of the picture is a vertical screen display direction.

The technical scheme shown in the embodiment of the application can screen the header files by identifying the header file identifications; then, reading the width and height of the picture loaded in the header file; 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 picture formats for the pictures downloaded in the network, for example: JPEG, PNG, etc. Each type of picture has its corresponding header identification. The technical scheme shown in the embodiment of the application establishes the corresponding relation between the picture format and the header file identifier in advance, and then stores the corresponding relation between the picture format and the header file identifier in a first list. The format of the first list may be referred to 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 the practical application process, the controller 250 can determine the picture format of the picture through the suffix of the picture. The controller 250 traverses a first list according to the picture format, and screens out a header file identifier corresponding to the picture format, wherein the first list is used for recording the corresponding relation between the picture format and the header file identifier; the controller 250 screens the header file from the picture based on the header file identification.

For example, the controller 250 receives a picture in which the suffix of the picture is. Gif. Determining the picture format of the picture as GIF; traversing table 1 to determine that the header file identifier corresponding to the GIF is: 47 49. The picture corresponding to "47 49" is determined to be the header file.

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

In particular, the data bits of the width and height information for the picture in each header are fixed. The technical scheme shown in the embodiment of the application establishes the corresponding relation between the header file identification and the data bits of the width and height information in advance, and then stores the corresponding relation between the header file identification and the data bits of the width and height information in a second list. The format of the second list may be referred to in table 2.

TABLE 2

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

For example, the controller 250 determines that the header file identification in the received picture is 42 d. Traversing Table 2, determining that the wide and high data bits corresponding to header file identification "42D" are wide: 0x0303, high: 0X01B2, calling the data corresponding to the size information data bit in the header file: the width is as follows: 771, height is: 434.

in a feasible embodiment, the width of the loaded picture is called by the controller 250 as follows: 771, height is: 434, the controller 250 determines that the picture is a cross-screen presentation picture. In another possible embodiment, the width of the loaded picture is called by the controller 250 as: 1024, height is: 956, the controller 250 determines that the picture is a portrait presentation picture.

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

And if the direction mark is transverse, the picture is a transverse screen display picture, and if the direction mark is longitudinal, the picture is a transverse screen display picture. The direction identifier can be added into the header file of the picture: com.android.jpg, H. H is a first identification value, the corresponding picture is a horizontal screen display picture, V is a first identification value, and the corresponding picture is a vertical screen display picture. The controller 250 can determine whether the picture is a horizontal screen display picture or a vertical screen display picture by reading the direction identification value of the picture through the controller 250. In the actual application process, the first identification value and the second identification value can be set according to the requirements. The applicant does not make any excessive restrictions herein.

In a feasible embodiment, the controller 250 invokes the direction identification of the loaded picture: com.android.jpg, H, then controller 250 determines that the picture is a landscape display picture. In another possible embodiment, the controller 250 invokes the directional identification of the loaded picture: com.android.jpg, V, then controller 250 determines that the picture is a portrait presentation 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 orientation 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 gravitational direction can be determined by measuring angular acceleration or the gravitational direction. And comparing the detected gesture data with gesture data in the horizontal screen display direction and the vertical screen display direction respectively to determine the current display direction of the display 275.

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 assembly 276, and the display direction in which the display 275 is currently positioned is determined by measuring the angle at which the rotating assembly 276 rotates, and comparing the angle with the angles 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 can be directly displayed. If the loaded picture does not coincide with the front display direction of the display 275, the display 275 is rotated so that the display direction of the display 275 coincides with the display direction of the picture.

For example, if the current rotation angle of the display 275 is detected to be 90 degrees by the angle sensor, it may be determined that the display direction of the display 275 is a portrait display direction. When the currently loaded picture is determined to be a horizontal screen display picture, the display direction of the picture is determined to be consistent with the display direction of the display 275, and the display 275 can be rotated so that the display direction of the display 275 is consistent with the display direction of the picture.

The display device 200 provided in the above embodiment determines whether the picture is a landscape display picture or a portrait display picture after receiving the picture pushed by the mobile terminal 1, and determines whether to control the display 275 to rotate according to the current display direction of the display 275. In the practical application process, the pictures stored in the mobile terminal 1 are mostly ordered according to the shooting time sequence, so that when the mobile terminal 1 pushes the pictures to the display device 200, the pictures are displayed on a horizontal screen, and the pictures 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 in displaying the picture.
