Description

Display device and rotation control method

Technical Field

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

Background

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

However, since the picture scales corresponding to different applications or media assets from different sources are different, the smart tv is often used to display pictures with different scales from the traditional video. For example, video resources shot by a terminal such as a mobile phone are generally vertical media resources with 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 term "module," as used in various embodiments of the present application, may refer to any known or later developed hardware, software, firmware, artificial intelligence, fuzzy logic, or combination of hardware and/or software code that is capable of performing the functionality associated with that element.

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

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

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

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

With the wide popularization of the application of the mobile phone, vertical videos and pictures occupy most media resources, and even many video service merchants can specially customize the content of the vertical resources. Therefore, the rotatable display device used in the vertical video playing and vertical picture browsing scenes can bring better user experience. In order to realize the rotation of the screen of the display device, the current screen rotation mode is usually driven around a remote controller, voice, playing video or a mobile phone screen. For example, the rotating component is driven to operate by pressing a "rotate" key provided on the remote controller. However, these driving rotation methods need to depend on the cooperation of an external device, the operation is complex, and the operation process depends on the prompt of a UI interface, and there is no more intuitive interactive experience.

Wherein, the transmission component can adjust the rotating speed and the torque output by the rotating component 276 through a specific transmission ratio, and can be in a gear transmission mode; the detection means may be composed of a sensor, such as an angle sensor, an attitude sensor, or the like, provided on the rotation shaft. These sensors may detect parameters such as the angle at which the rotating assembly 276 is rotated and transmit the detected parameters to the controller 250, so that the controller 250 can determine or adjust the state of the display apparatus 200 according to the detected parameters. In practice, rotating assembly 276 may include, but is not limited to, one or more of the components described above.

The touch member 277, the touch member 277 may be disposed on a display screen of the display 275 to detect a touch action of the user. The controller 250 may obtain a touch command input by a user through the touch device 277, and respond to different control actions according to different touch commands.

The touch instruction input by the user may include various forms according to different touch actions corresponding to the touch instruction. Such as a click, slide, long press, etc. If the touch device 277 supports multi-touch, a form of touch command may be further added, such as a double-finger click, a double-finger slide, a double-finger long press, a three-finger click, a three-finger slide … …, and so on. Different types of touch commands may represent different control actions. For example, a click action performed on an application icon may represent launching an application program corresponding to the icon.

The RAM251, the ROM252, the graphic processor 253, and the CPU processor 254 are connected to each other through a communication bus 256 through a communication interface 255.

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

The application layer, the application programs built in the system and the non-system-level application programs belong to the application layer. Is responsible for direct interaction with the user. The application layer may include a plurality of applications such as a setup application, a post application, a media center application, and the like. These applications may be implemented as Web applications that execute based on a WebKit engine, and in particular may be developed and executed based on HTML5(HyperText Markup Language), Cascading Style Sheets (CSS), and JavaScript.

The middleware layer may provide some standardized interfaces to support the operation of various environments and systems. For example, the middleware layer may be implemented as multimedia and hypermedia information coding experts group (MHEG) middleware related to data broadcasting, DLNA middleware which is middleware related to communication with an external device, middleware which provides a browser environment in which each application program in the display device operates, and the like.

The kernel layer provides core system services, such as: file management, memory management, process management, network management, system security authority management and the like. The kernel layer may be implemented as a kernel based on various operating systems, for example, a kernel based on the Linux operating system.

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, 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 the technical solution provided in the present application, the rotation operation of the display device 200 refers to an angle adjustment process that is completed by the rotation component 276 driving the display 275, so that the placement angle of the display 275 is changed. Generally, the rotation assembly 276 may rotate the display 275 in a vertical plane perpendicular to the ground, thereby placing the display 275 in different rotational positions.

The rotation state is a plurality of specific states in which the display 275 is positioned, and may be set in various forms according to the posture of the display 275, for example, a landscape state, a portrait state, a tilted state, and the like. The landscape screen state and the portrait screen state are rotation states used by most users, and can be respectively suitable for landscape screen scenes and portrait screen scenes. Therefore, in some embodiments of the present application, the landscape state and the portrait state may be referred to as a standard state. While the tilted state is generally a state in which the display 275 is not rotated in place due to a failure of the rotating assembly 276, the user rarely rotates the display 275 to the tilted state intentionally. That is, in some embodiments of the present application, the tilted state may also be referred to as a non-standard state.

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

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

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

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

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

In order to adjust the rotation state of the display 275, as shown in fig. 6A, some embodiments of the present application provide a rotation control method, including the steps of:

s1: and acquiring a touch instruction which is input by a user and used for rotating the display.

A user may input a touch command for rotating the display 275 through the touch member 277. The specific touch instruction form may be one or more of "click, slide, and long press" according to the system UI interaction policy. However, in order to effectively distinguish the touch operation from other touch operation modes and reduce the misoperation, the touch command for rotating the display 275 may be more unique or complex relative to other operations.

For example, according to the operation habit of the user on the touch screen terminal, the single-finger click, slide, and long-press touch instruction is generally used for "starting the program", "moving the position", and "expanding operation", and thus the touch instruction for rotating the display 275 may be a multi-finger click, slide, long-press touch instruction, or the like, so as to be distinguished from the single-finger click, slide, and long-press touch instruction.

Obviously, the touch command for rotating the display 275 may be one or more of two-finger touch, three-finger touch, four-finger touch, or five-finger touch. For example, the touch instruction for rotating the display 275 may be a five-finger touch instruction, and the touch instruction for rotating the display 275 may also be a multi-finger touch instruction, that is, when a user inputs an instruction of a two-finger touch, a three-finger touch, a four-finger touch, and a five-finger touch, the operation of the rotating display 275 can be triggered, as shown in fig. 6B.

In some embodiments, the touch instruction for rotating the display 275 may include two partial actions, namely a touch action part and a rotation action part, wherein the touch action part is used for triggering the controller 250 to detect the touch action corresponding to the touch instruction to determine whether to start rotating. The rotation action portion may be input after the touch action portion to assist in determining whether to trigger rotation and controlling the manner of rotation of the rotating assembly 276, including control of parameters such as direction of rotation, angle of rotation, etc.

S2: and responding to the touch instruction, and extracting a touch action corresponding to the touch instruction.

After acquiring the touch instruction for rotating the display 275, the controller 250 of the display device 200 may extract a touch action corresponding to the touch instruction in response to the touch instruction.

According to different interaction actions corresponding to the preset touch instruction, the extraction manner of the touch action corresponding to the touch instruction by the controller 250 in the actual application is also different. When the touch command is a continuous motion, the controller 250 may extract the touch motion directly by detecting signal data corresponding to the touch command. For example, if the operating system sets the touch command for rotating the display 275 to draw an "O" shaped pattern on the screen, the controller 250 needs the user to extract the touch action in the touch command after inputting the touch command.

And when the touch instruction comprises two (or more) parts, the rotation action part input after the touch action part is detected can be triggered after the touch action part is received. For example, the operating system sets the touch instruction for rotating the display 275 to a five-finger rotation motion, and during the operation, the user may input the touch instruction of the five fingers first, that is, touch the screen with the five fingers. After the controller 250 detects that the five fingers touch the display through the touch module 277, the detection program may be further started to detect a subsequent rotation input by the user on the screen, and perform control of the rotation process of the display 275 according to the specific rotation.

S3: and if the touch control action is the same as the preset rotation action, controlling a rotation assembly to adjust the rotation state of the display.

After extracting the touch action, the controller 250 may also compare the extracted touch action with a preset rotation action, and if the touch action is the same as the preset rotation action, determine that the user is to rotate the display 275, and thus may control the rotation component 276 to start running to adjust the rotation state of the display 275.

For example, when the rotation state includes a landscape state and a portrait state, the controller 250 may first acquire a current rotation state of the display 275 after determining that the touch motion is the same as a preset rotation motion. Controlling the rotating assembly 276 to adjust the display 275 to the portrait state if the current rotation state of the display 275 is the landscape state; if the current rotation state of the display 275 is the portrait state, the control rotation assembly 276 adjusts the display 275 to the landscape state.

During the operation of the rotating assembly 276, the controller 250 may send a control command to the rotating assembly 276, so that the rotating assembly 276 rotates according to the control command after receiving the control command. The control instructions may include, among other things, some basic operational parameters for controlling the rotation of the rotating assembly 276, such as the direction of rotation, the angle of rotation, and the like.

The specific value of the parameter in the control command may be determined according to the current rotation state and the specific rotation manner, for example, when the display 275 is in the horizontal screen state, if the touch action is the same as the preset rotation action, the rotation component 276 may be controlled to rotate clockwise by 90 degrees, so as to adjust the display 275 to the vertical screen state; similarly, when the display 275 is in the vertical screen state, if the touch is the same as the predetermined rotation, the rotation component 276 may be controlled to rotate 90 degrees counterclockwise to adjust the display 275 to the horizontal screen state.

The specific values of the parameters in the control command can also be determined according to the touch control action input by the user. For example, if the rotational motion input by the user is a clockwise motion, the rotating assembly 276 may be controlled to rotate clockwise 90 degrees to a corresponding rotational state. If the rotational motion input by the user is a counterclockwise motion, the rotating assembly 276 may be controlled to rotate 90 degrees counterclockwise to a corresponding rotational state.

According to the technical scheme, after the user inputs the touch instruction, the rotation control method provided by the application can extract the touch action corresponding to the touch instruction and compare the touch action with the preset rotation action. Thereby controlling the rotation component 276 to start rotating to adjust the rotation state of the display 275 when the touch action is the same as the preset rotation action. A rotational control manner is implemented that drives the display 275 based on gesture touch detection.

Since the touch operation cannot be implemented on a specific UI interface like the conventional UI interface interactive operation, and the user is guided to complete the operation through the text prompt, in practical applications, the user needs to remember the specific action of the touch operation to be able to implement the rotation operation on the display 275, which affects the user experience. In order to facilitate the user to remember the specific interaction action, in some embodiments of the present application, the user may be guided to complete the touch interaction by displaying a prompt UI interface. As shown in fig. 7A, the step of obtaining the touch instruction for rotating the display further includes:

s101: detecting the number of touch points in the touch instruction;

s102: and if the number of the touch points is equal to the preset judgment number, controlling the display to display a prompt UI interface.

After the user inputs the touch command, the controller 250 may detect the number of touch points in the touch command through the touch device 277 and determine whether the number of touch points is equal to a predetermined determination number, so as to control the display 275 to display a prompt UI interface. And the prompt UI interface comprises patterns and/or characters for indicating the rotation action. The preset judgment number can be set according to the actual UI interaction rule of the operating system, and when the number of touch points in the touch instruction is different, different prompt UI interfaces can be displayed.

For example, as shown in fig. 7B, the user may input a touch instruction by simultaneously touching the screen with multiple fingers. When the controller 250 detects a multi-finger touch operation of the user through the touch module 277, the number of touch points in the touch operation can be detected. If the number of the touch points is 5 and is equal to the preset judgment value 5, it is determined that the current user may input a touch instruction for rotating the display 275, and therefore, the display 275 may be controlled to display a UI interface for prompting a rotation operation, so that the user is prompted to complete a subsequent rotation action input by prompting a pattern and/or text on the UI interface.

In the prompt UI interface, the user can be prompted to complete the input through more intuitive contents such as animation, video and the like. The prompt UI interface can be displayed on the uppermost layer of the display screen in a semitransparent mode, and the display state is kept in the process that a user touches the screen until the user finishes the subsequent rotation action.

In addition, in order to facilitate the user to remember more touch gesture actions, a general function entry based on a unified touch operation may be further provided in the control system of the display device 200. In any scene, a user can call the prompt UI interface through a set touch action, and different interactive actions are respectively indicated in the prompt UI interface in the form of a plurality of graphs, characters or animations, so that the user can input according to the prompt UI interface.

For example, a wake-up action of the global function entry may be defined as a five-finger touch command, and a prompt UI interface is displayed after the user passes through the five-finger touch screen. A function entrance control can be directly set in the prompt UI, so that when a user clicks the control, the corresponding function is realized. The UI interface may also be prompted to sequentially display an animation of gestures corresponding to multiple functions, for example, an animation of multi-finger rotation indicates that the user may start the rotation component 276 to rotate through a multi-finger rotation instruction; animation of a slide down with a single finger indicates that a user may view a message interface via a single-finger slide down instruction, and so on.

It should be noted that, when the user inputs the touch instruction, the fingers are in surface contact with the touch screen, that is, a continuous contact area is formed between one finger and the screen, so the number of the touch points may be the number of the continuous contact areas in the interaction process.

According to the technical scheme, in the embodiment, the number of the touch points in the touch instruction is detected, and the prompt UI is displayed when the number of the touch points is equal to the preset judgment number, so that a user does not need to remember a plurality of touch modes, and the user can input interactive actions more accurately, and the controller 250 can execute corresponding functions after judging.

For the rotation motion input by the user, different detection modes can be provided according to different input motions. For a rotation motion requiring a slide on the screen, it is possible to determine as which motion a touch motion input by the user is by judging a slide trajectory of a touch point. That is, in some embodiments of the present application, as shown in fig. 8A, the step of extracting the touch action corresponding to the touch instruction includes:

s201: traversing the touch point coordinates in the touch instruction;

s202: generating a touch action track according to the continuous touch point coordinates;

s203: and comparing the shape of the touch action track with the shape of a preset rotation action track to generate a comparison result, and determining whether the touch action is the same as the preset rotation action according to the comparison result.

To enable detection of touch input, a planar coordinate system may be constructed within the screen of the display 275, such that any position on the touch-sensitive element 277 may be represented by the constructed planar coordinate system. When the user finger touches any position on the screen, the touch position can be represented by the touch point coordinates. And in a period of time, the detected continuous touch point coordinates can be used for representing the touch action track of the user.

Obviously, the detected motion trajectory may be graphic data composed of a plurality of touch point coordinates. By comparing the shape of the touch action track with the shape of the preset rotation action track, it can be determined whether the touch action is the same as the preset rotation action. The shape of the extracted touch action track has various forms because the action amplitude of the user input touch operation is different, and in order to determine whether the touch action is the same as the preset rotation action, the shape type of the track can be directly judged, and if the shape of the touch action track is the same as the shape of the preset rotation action track, the touch action is determined to be the same as the preset rotation action.

For example, as shown in fig. 8B, if the shape of the touch motion trajectory and the shape of the preset rotation motion trajectory are both "O" shapes, it is determined that the touch motion is the same as the preset rotation motion, and the "O" shape with the larger diameter and the "O" shape with the smaller diameter input by the user can be determined that the preset rotation motion is input, so as to control the rotation component 276 to rotate the display 275. Similarly, if the shape of the touch action track and the shape of the preset rotation action track are both "circular", "rectangular", "triangular", "quadrilateral", etc., it may also be determined that the touch action is the same as the preset rotation action.

According to the technical scheme, the embodiment can detect the shape of the touch action track formed by the continuous touch point coordinates by traversing the touch point coordinates in the touch instruction, and determine whether the touch action is the same as the preset rotation action by comparing whether the shape of the touch action track is the same as the shape of the preset rotation action track. The embodiment can improve the fault tolerance rate of the system in the judging process, so that a user can control the rotating process of the rotating assembly without inputting the action which is completely the same as the preset rotating action.

In some embodiments of the present application, the action of the rotating component 276 may be further controlled by a rotating action command input after the touch command, that is, as shown in fig. 9, the step of controlling the rotating component to adjust the rotating state of the display further includes:

s310: acquiring a rotation action instruction input by a user;

s320: extracting a rotation motion direction in response to the rotation motion instruction;

s330: and controlling the rotating assembly to rotate the display according to the same direction as the rotating action direction.

Wherein, the rotation action instruction refers to a sliding action which can be executed by the user on the screen. Taking a five-finger touch manner as an example, a user may input a rotation motion instruction by simultaneously sliding an arc-shaped track with five fingers on the screen. The rotating action command can be the same continuous action as the previously input touch command, namely after the five-finger touch operation is input, the rotating action can be directly input through the sliding arc-shaped track. The rotation instruction may also be two discrete actions with respect to the previously input touch instruction, for example, the touch instruction may be input by a five-finger touch action, and the rotation instruction may be a five-finger rotation action input after the five-finger touch action triggers the display of the prompt UI interface.

After the rotation motion command is obtained, the controller 250 may determine a rotation direction corresponding to the rotation motion command according to a time sequence variation characteristic of the touch point coordinate. For example, when new touch point coordinates are added in a clockwise direction based on the initial touch point coordinates in the rotation operation command, the rotation direction is determined to be the clockwise direction.

The controller 250 controls the rotating member 276 to rotate the display 275 in the same direction as the rotating direction according to the rotating direction, thereby adjusting the rotating state of the display 275. In some embodiments, the controller 250 may first detect the current rotation state of the display 275, as well as the adjacent rotation state to the current rotation state. Among the adjacent states, that is, the other rotation states different from the current rotation state, there are two rotation states having the smallest angle difference from the current rotation state. For example, when the current rotation state is the landscape state, the two rotation states with the smallest angle difference therebetween are the "+ 90 ° vertical screen state" and the "-90 ° vertical screen state", respectively.

And then, according to the determined rotation direction, the rotation assembly 276 is controlled to rotate, thereby rotating the display 275 to the adjacent state corresponding to the rotation direction. That is, if the rotational motion direction is clockwise rotation, the control rotating member 276 clockwise rotates the display 275 to the adjacent rotational state. For example, display 275 is rotated clockwise 90 from the landscape state to the "+ 90 vertical state". Similarly, if the rotation direction is counterclockwise, the rotation assembly is controlled to rotate the display counterclockwise to the adjacent rotation state. For example, display 275 is rotated 90 counterclockwise from the landscape state to the "-90 portrait state".

In some embodiments, as shown in fig. 10, after the step of obtaining the rotation motion command input by the user, the rotation control method further includes:

s311: extracting a bending angle of a touch point track in the rotating action instruction;

s312: if the bending angle is larger than or equal to a preset starting threshold value, sending a control instruction to the rotating assembly to enable the rotating assembly to rotate;

s313: and if the bending angle is smaller than a preset starting threshold value, controlling the display to display a prompt UI interface.

The controller 250 may extract a bending angle corresponding to the touch point trajectory in the rotation motion instruction, where the bending angle may be a bending angle of the trajectory graph, or may also be a determination angle corresponding to the trajectory graph, for example, the bending angle may be a central angle corresponding to the arc-shaped trajectory.

After the bending angle of the touch point trajectory is extracted, the bending angle may be compared with a preset starting angle threshold, so that when the bending angle is greater than or equal to the preset starting threshold, a control instruction is sent to the rotating component 276 to start rotating the rotating component 276. For example, it may be set that when the rotation angle exceeds 20 degrees, the rotation is activated, and when the bending angle of the touch point trajectory is less than 20 °, the rotation of the rotation component 276 is not activated and the prompt UI interface is still displayed on the display 275 to guide the user to continue rotating to activate the rotation component 276. And when the bending angle of the touch point trajectory is greater than or equal to 20 °, a control command is sent to the rotating member 276 to start rotating the rotating member 276.

According to the above technical solution, in the above embodiment, the bending angle of the touch point trajectory may be detected, and compared with the preset starting threshold, so that the rotating assembly 276 is started to rotate when the rotation angle corresponding to the rotation action command is larger, thereby alleviating the misoperation of the user, i.e., preventing the frequent triggering of the rotation action. Meanwhile, the user can be guided to accurately complete the input of the rotation action instruction by prompting the UI picture, so that the rotation can be smoothly completed when the user wants to perform the rotation operation.

In some embodiments of the present application, the rotational state further includes a tilt state. In general, the display device 200 may not maintain a tilted state for a long time under normal use, and the tilted state is usually caused by an abnormal condition, such as a stalling phenomenon caused by a mechanical hardware failure, a foreign object jam, etc., i.e., the rotating member 276 does not rotate the display 275 to a predetermined position during rotation. The tilt state will affect the viewing experience of the user. Therefore, if the current rotation state of the display 275 is the inclined state, the rotation control method further includes:

and after the touch control instruction is acquired, controlling the rotating assembly to rotate the display to a horizontal screen state or a vertical screen state with the smallest angle difference with the inclined state.

The controller 250 may detect the current rotation state of the display 275 through a gravitational angular velocity sensor or the like built in the display device 200. For example, when it is detected that the current rotation state of the display 275 is tilted by +5 degrees, the landscape state or the portrait state, which is the smallest angle from the current tilt state, may be determined according to the detected tilt angle. It can be seen that the angle difference between the landscape screen state and the current tilt state is 5 degrees, and the angle difference between the portrait screen state and the current tilt state is 85 degrees, so that the rotating assembly 276 can be controlled to rotate counterclockwise by 5 degrees to the landscape screen state.

In order to rapidly rotate to the target state, the controller 250 may further control the rotating assembly 276 to rotate the display 275 to the landscape state or the portrait state according to the rotating motion direction after acquiring the rotating motion command. For example, when it is detected that the current rotation state of the display 275 is tilted by +5 degrees and the rotation direction corresponding to the rotation motion command input by the user on the screen is clockwise, the display 275 is rotated by 85 degrees in the clockwise direction to be adjusted to the portrait state although the angle difference between the landscape state and the current tilt state is 5 degrees.

As can be seen from the above technical solutions, the above embodiments may correct the tilting state of the display 275 when it is detected that the rotation state of the display 275 is the tilting state, so as to maintain the display 275 in the standard state suitable for the user to view. Meanwhile, the rotating process is not influenced.

Based on the above rotation control method, as shown in fig. 11, some embodiments of the present application further provide a display device 200, including: a display 275, a rotating component 276, a touch component 277, and a controller 250. Wherein the display 275 is configured to present a specific user interface or play screen. The rotation assembly 276 coupled to the display 275 is configured to rotate the display 275 such that the display 275 is in one of a plurality of rotational states. The touch member 277 is disposed on a screen of the display 275 and configured to detect a touch command input by a user. The display 275, the rotating element 276, and the touch element 277 are all electrically connected to the controller 250.

And, the above-mentioned controller 250 is configured to execute the following program steps:

s1: acquiring a touch instruction for rotating the display;

s2: responding to the touch instruction, and extracting a touch action corresponding to the touch instruction;

s3: and if the touch control action is the same as a preset rotation action, controlling the rotation assembly to adjust the rotation state of the display.

In practical applications, the controller 250 may obtain a touch instruction for rotating the display 275 through the touch device 277, extract a touch action corresponding to the touch instruction through data detected by the touch device 277, and determine whether the touch action is the same as a preset rotation action, so as to control the rotation device 2756 to adjust the rotation state of the display 275.

As can be seen from the above technical solutions, the present application provides a display apparatus 200 and a rotation control method, which can be applied to the display apparatus 200 for adjusting a rotation state of a display 275 in the display apparatus 200. After acquiring a touch instruction for rotating the display 275, which is input by a user, the method may respond to the touch instruction, extract a touch action corresponding to the touch instruction, and compare the touch action with a preset rotation action. If the touch is the same as the predetermined rotation, the rotation component 276 is controlled to adjust the rotation status of the display 275.

The method can control the rotation of the rotating component 276 in a touch interaction mode, so that when a finger of a user presses on the touch component 277, detection is triggered, and when a detection result accords with a preset rotation action, the display device 200 is driven to rotate, so that the user can freely operate the rotation of the display device 200 without depending on peripherals such as a remote controller.

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.
