In order to meet different user requirements, some display devices are provided with two displays, namely a first display and a second display, wherein the function of the first display is similar to that of a normal display device and is used for playing media assets; the second display is used for showing some recommendation information.
The display device provided in this embodiment is described below with reference to the accompanying drawings, and fig. 1 and 2 are schematic diagrams of a display device provided in a possible embodiment, where the display device includes:
a first display 1;
and the display screen 2 is arranged on the upper side or the rear side of the first display in a lifting manner and comprises a second display 21. In some embodiments, the second display is raised when the computer is turned on, the second display is disposed on the upper side of the first display, and the bottom end of the second display is as high as the top end of the first display; when the second display is folded, the second display is arranged behind the first display, when the second display is turned off, the second display falls, and the top end of the second display is not higher than that of the first display;
a driving component (not shown in the figure) connected to the second display for driving the second display to ascend or retract;
the drive assembly may be a motor as a possible embodiment.
A second controller (not shown in the figure) connected with the driving assembly and used for controlling the driving assembly to move; the second display is connected and used for controlling the second display to display the recommendation information;
a first controller (not shown) connected to the second controller for communication with the second controller; and the first display is connected and used for controlling the first display to display the playing picture.
In the display device disclosed in this embodiment, when the display device is turned off, the second display is located behind the first display, and specifically, the display device shown in fig. 2 may be referred to. Fig. 2 is a rear view of the display device according to a possible embodiment, and it can be seen that the top end of the second display 2 is not higher than the top end of the first display 1. When switched on, the second display element is raised until the bottom end of the viewing area 21 is located above the top end of the first display, in particular, as can be seen in the display device shown in fig. 1. Fig. 1 is a front view of a display device according to a possible embodiment, and it can be seen that the bottom end of the information presentation member 21 is located above the top end of the first display. When the information display device works normally, the bottom end of the information display part is always positioned on the upper side of the first display.
In practical applications, the first controller and the second controller may be integrated into one controller, and the corresponding display device includes the first display, the second display, the driving assembly and the controller. Wherein, the controller is connected with the first display and the second display simultaneously.
As a feasible embodiment, the display screen further comprises: referring to fig. 3, fig. 3 is a schematic diagram of a display device according to a possible embodiment, where the camera 22 is located below the second display.
As a possible embodiment, the first controller is further configured to; responding to a received starting instruction output by a user, and sending a starting instruction to the second controller; the second controller is further configured to: and responding to a starting instruction sent by the first controller, and controlling the driving assembly to drive the display screen to ascend to the bottom end of the second display to be as high as the top end of the first display.
In the technical solution shown in this embodiment, the first controller is connected to the user interface and configured to receive a power-on instruction input by a user. In response to receiving a starting instruction output by a user, the first controller sends a starting instruction to the second controller. And the second controller responds to the starting instruction sent by the first controller and controls the driving component to drive the second display to ascend to the bottom end of the second display and the top end of the first display are equal in height.
It is worth noting that after the technical scheme shown in this embodiment is turned on, the camera does not leak the first display, that is, the camera is still disposed behind the first display, and only when the first application (in this application, the first application needs the camera to acquire an image when the first application is started) is in a start state, the camera is higher than the first display (that is, the bottom end of the camera is as high as the top end of the first display). A specific implementation may be that the second controller is further configured to, in response to the activation of the magic mirror application, control the driving assembly to drive the second display to ascend until the camera head leaks out of the first display. And responding to the closing of the magic mirror application, and controlling the driving component to drive the second display to be folded until the camera is shielded by the first display.
For example, in a possible embodiment where the height of the camera is 2cm, the second controller controls the driving assembly to drive the second display to ascend by 2cm in response to the activation of the magic mirror application. And the second controller responds to the closing of the magic mirror application and controls the driving assembly to drive the second display to be folded by 2 cm.
In order to improve the experience of the user, the second display can be controlled to display the shutdown animation in the shutdown process. Specifically, during the shutdown process, the second display displays the shutdown animation, and meanwhile, the second display gradually drops to the back of the first display. However, since there is no association between the descending process of the second display and the shutdown animation, it may be caused that the shutdown animation has not been played yet, the second display has descended to the back of the first display, or the second display has descended, and the shutdown animation has finished playing, so that the user experience is poor.
In order to solve the above technical problem, on the basis of the display device shown in the above embodiment, the present embodiment further improves the display device, where the display device at least includes: the display device comprises a controller, a first display, a display screen and a driving assembly. Wherein the display screen comprises at least a second display.
In this embodiment, the first display is used for displaying a playing interface;
in the application, the first display shows the playing interface after the display device is started. The playing interface can show different contents in different application scenes. The content presented by the playing interface may be, but is not limited to: starting up animation, media resources and system homepage. For example, in the process of starting up the display device, the playing interface may display the startup animation; the display equipment completes the preparation work of starting up, and the playing interface jumps from the starting-up animation to the large screen home page. In this embodiment, the content of the large-screen home page is not limited, for example, in some feasible embodiments, the large-screen home page may display an icon of the display device installation application, and in some feasible embodiments, the large-screen home page may display a search interface. And under the application scene of the video APP started by the user, the media assets can be played through the playing interface. It should be noted that, this embodiment is only an exemplary content showing several play pages, and the content is not limited to the above, and in the process of practical application, the content shown in the play interface may be, but is not limited to, the above several contents.
In the application, the second display shows different contents in different application scenes. The content of the second display may be, but is not limited to: starting-up animation, recommending an interface, a small-screen home page, closing-up animation and the like. For example, during the power-on process of the display device, if the second controller is in the raised state (i.e. the height of the bottom end of the second display is greater than the height of the top end of the first display), the second display may play the display power-on animation. As a feasible embodiment, the boot animation displayed by the first display and the boot animation displayed by the second display may be linked to improve the experience of the user, for example, the animation image in the boot animation may jump from the first display to the second display; and the display equipment completes the preparation work of starting up, and the content displayed by the second display jumps from the starting-up animation to the small-screen home page. In this embodiment, the content of the small-screen home page is not limited, for example, in some feasible embodiments, the small-screen home page may display a weather forecast, and in some feasible embodiments, the large-screen home page may display some social news in a scrolling manner. And in the process of shutdown, the second display is used for displaying shutdown animation. (the details of the motor-related picture will be described later).
The display device shown in this embodiment may set the raising or lowering of the second display according to the user's needs, for example: in some feasible embodiments, the lifted or retracted state of the second display may be synchronized with the on or off state of the display device, that is, when the display device is powered on, the second display is controlled to be lifted above the first display, and when the display device is in the on state, the second display may be always located above the first display, so that the user may know the real-time message at any time through the real-time message displayed by the second display. When the display equipment is turned off, the second display is controlled to be folded behind the first display, so that the purpose of saving space is achieved. In some possible embodiments, the raised or stowed state of the second display may not be synchronized with the on or off state of the display device.
In the following embodiments, the raised or stowed state of the second display may be described in synchronization with the on or off state of the display device.
In the application, the driving component is connected with the display screen and used for driving the display screen to rise or fall; in this application, the kind of the driving assembly is not limited, and any assembly that can perform control based on the controller and drive the display screen to ascend or descend can be applied to the scheme shown in this embodiment as the driving assembly, for example, in a feasible embodiment, the driving assembly may be a motor. In the shutdown process, the driving assembly drives the display screen to descend from the upper part of the first display to the rear part of the first display, when the display screen is positioned above the first display, the second display leaks out of the first display, and when the display screen is positioned behind the first display, the second display is shielded by the first display; fig. 4 is a schematic diagram illustrating a position change of the first display and the second display during the shutdown process according to a possible embodiment. In normal operation of the display device, the second display 44 is located above the first display, as can be seen in particular in effect 41 of fig. 4. In the shutdown process, the driving assembly (not shown in the figure) drives the second display to descend, and in the descending process of the second display, the height of the second display leaking out of the first display is gradually reduced, specifically, see effects 41 to 43 in fig. 4. Finally, the driving component drives the second display to descend to the rear of the first display, specifically referring to effect 43 in fig. 4, at the user's angle, the second display is not visible.
The operation of the display device is described below with reference to the following specific drawings: FIG. 5 is a flow chart illustrating interaction among components of a display device according to a possible embodiment:
the controller is configured to perform S51: responding to a shutdown instruction, and controlling the second display to play shutdown animation;
in this embodiment, the shutdown instruction may be triggered by a user, and there are various implementation manners for triggering the shutdown instruction by the user. As a feasible implementation manner, a user can trigger a shutdown instruction through a shutdown key on the touch remote controller; as a feasible implementation manner, the user may trigger the shutdown instruction through a shutdown key on the touch display device. The shutdown command is actively triggered by the displayable device. For example, the user may set a shutdown time, and when the system time of the display device is equal to the shutdown time, the display device actively triggers a shutdown instruction. The embodiment merely describes several implementation manners of triggering the shutdown instruction by the user, and the implementation manners of triggering the shutdown instruction in the actual application process may be, but are not limited to, the above several manners.
The controller is configured to perform S52: calculating screen descending speed according to the remaining playing time and the height of the second display leaking out of the first display;
in this embodiment, the height of the second display leaking out of the first display is a relative value, and specifically, may be a difference between the height of the top end of the second display and the height of the top end of the first display. In this embodiment, the height of the top end of the first display is a fixed value, so the controller only needs to read the height of the top end of the second display, and then the height of the top end of the first display is subtracted from the height of the top end of the second display to obtain the height of the second display leaking out of the first display. Fig. 6 is a schematic diagram of a display device provided in a possible embodiment, and it can be seen that the height 61 of the second display leaking out of the first display is the height difference between the top of the second display and the top of the first display.
There are various ways to obtain the remaining playing time.
As a feasible implementation, the remaining playing time is equal to the playing duration of the shutdown animation. For example, in some application scenarios, the controller controls the second display to play the shutdown animation and controls the driving component to drive the display screen to descend at the same time, in which case, the remaining playing time is equal to the playing time of the shutdown animation (which may also be referred to as the total playing time in this embodiment).
In this embodiment, the screen reduction Speed may be calculated according to the following formula: speed is the height the second display leaks out of the first display/LeftTime, where LeftTime is the remaining playing time, which may be abbreviated as LT.
The controller is configured to perform S53: and controlling the driving component to drive the display screen to descend according to the screen descending speed, so that when the shutdown animation bundle is played, the driving component drives the display screen to descend behind the first display.
Therefore, in the display device shown in this embodiment, in the shutdown process, the controller controls the second display to play the shutdown animation, and controls the driving component to drive the display screen to descend, wherein the display screen descends according to the screen descending speed. Because, the screen dropping speed is related to the remaining playing time of the shutdown animation and the height of the second display leaking the first display, the driving assembly drives the display screen to drop to the rear of the first display when the shutdown animation is played, and the user experience is better.
In the process of practical application, in order to further improve the synchronism of the playing of the shutdown animation and the descending of the display screen, the controller can recalculate a real-time screen descending speed at preset intervals. Then, the controller adjusts the descending speed of the display screen at any time based on the real-time descending speed so as to improve the synchronism of the playing of the shutdown animation and the descending of the display screen. The implementation of the above process is described below with reference to specific figures. Fig. 7 is a flowchart of a display screen control method provided in a feasible embodiment, and on the basis of the display device shown in the above embodiment, the controller is further configured to perform: S71-S72:
in S71, calculating a real-time screen reduction speed at preset intervals;
in this embodiment, the preset time may be predefined according to the requirement, for example, in some feasibility embodiments, the preset time may be 0.1s, and in some feasibility embodiments, the preset time may be 0.2 s. For example, in some feasibility embodiments the preset time may be half the play time.
In this embodiment, the remaining playing time is equal to the difference between the playing time of the shutdown animation and the current playing time. For example, in a feasible embodiment, the playing time length of the shutdown animation is equal to 60s, the current playing time length is 2s, and the remaining playing time length is equal to 60s-2 s-58 s.
And if the height of the second display leaking out of the first display is equal to 25cm, the calculated real-time screen dropping speed is 25cm/58 s.
In S72, generating a real-time screen reduction speed each time, and controlling the driving assembly to drive the display screen to reduce according to the real-time screen reduction speed.
In this embodiment, the controller may recalculate a real-time screen reduction speed every preset time interval. Then, the controller adjusts the descending speed of the display screen at any time based on the real-time descending speed. According to the technical scheme, even if the problem that the playing of the shutdown animation is asynchronous with the descending of the display screen occurs in the shutdown process, the controller can adjust the descending process of the display screen according to the real-time screen descending speed so as to ensure that the playing of the shutdown animation is synchronous with the descending of the display screen.
Because, the driving component drives the display screen component to descend in the shutdown process. During the lowering process, the height at which the second display leaks out of the first display gradually decreases. If the height of the frame picture contained in the shutdown animation is always kept unchanged, in the descending process of the display screen, partial content of the frame picture is shielded by the first display, and the user experience is poor.
In order to improve the experience of the user, the shutdown animation is further adjusted in the embodiment. In this embodiment, the shutdown animation at least includes a first sub-animation, the first sub-animation includes at least one first frame of picture, and in a playing process of the first sub-animation, as a playing time extends, heights of the first frame of picture displayed on the second display sequentially decrease. The first sub-animation will be described with reference to the specific drawings. Fig. 8 is a schematic diagram illustrating a change of a first frame during a first sub-animation playback process according to a possible embodiment. It can be seen that as the playing time is prolonged, the height of the first frame picture is sequentially reduced.
In some application scenarios, if the height of the first frame of picture is larger than the height of the second display leaking out of the first display, part of the content of the first frame of picture is also occluded. In order to solve the above technical problem, the present embodiment further provides a method for displaying a first frame, and a process of displaying the first frame is described below with reference to specific drawings. Fig. 9 is a flowchart of a first frame display method provided by a feasible embodiment, and on the basis of the display device shown in the above embodiment, the controller is further configured to execute S91-S93:
in S91, when the second display plays the first sub-animation, controlling the driving component to drive the display screen to descend according to the screen descending speed, and reading the height of the first frame of picture and the height of the second display leaking out of the first display;
the implementation manner of controlling the driving component to drive the display screen to descend according to the screen descending speed may refer to the above embodiments, and is not described herein again.
The height of the first frame picture can be read by, but is not limited to, configuring a height identifier for each first frame picture in advance. Before the first frame picture needs to be displayed, the controller can determine the height of the first frame picture by reading the height identifier.
In S92, controlling the second display to display the first frame picture if the height of the first frame picture is less than or equal to the height of the second display leaking out of the first display;
if the height of the first frame of picture is less than or equal to the height of the second display leaking out of the first display, the content contained in the first frame of picture can be completely displayed on the part of the second display leaking out of the first display, and therefore the user can be ensured to view the whole content contained in the first frame of picture.
In S93, if the height of the first frame is greater than the height of the second display leaking out of the first display, the second display is controlled not to display the first frame, and the height of the first frame and the height of the second display of the next frame are read.
If the height of the first frame of picture is greater than the height of the second display leaking out of the first display, the content contained in the first frame of picture cannot be completely displayed on the part of the second display leaking out of the first display, and a complete frame of picture cannot be seen from the user, so that the experience of the user is influenced.
In this embodiment, if the height of the first frame of picture is greater than the height of the second display leaking out of the first display, the second display is controlled not to display the first frame of picture, and the height of the first frame of picture and the height of the second display in the next frame of picture are read until the height of the first frame of picture is less than or equal to the height of the second display leaking out of the first display, so as to ensure that the user can see all the contents in the first frame of picture.
The embodiment of the present application further shows a shutdown animation, where the shutdown animation includes a first sub-animation and a second sub-animation, where the second sub-animation is played before the first sub-animation, the second sub-animation includes at least one second frame picture, and in a playing process of the second sub-animation, a height of the second frame picture is unchanged along with an extension of a playing time.
The following description of the shutdown animation is provided with reference to the specific drawings. Fig. 10 is a schematic diagram of changes of frame pictures during shutdown animation playback according to a possible embodiment. In this embodiment, the shutdown animation includes a first sub-animation and a second sub-animation, and the frame pictures include a first frame picture and a second frame picture. It can be seen that, during the playing process of the shutdown animation, the second sub-animation is played first, and during the playing process of the second sub-animation, as the playing time is prolonged, the height of the second frame of picture is not changed, which may specifically refer to effects 101 to 103 in fig. 10. After the playing of the second sub-animation is finished, the playing of the first sub-animation is started, and in the playing process of the first sub-animation, as the playing time is prolonged, the first frame of picture is sequentially reduced, which may specifically refer to effects 104 to 106 in fig. 10.
And aiming at the application scene of which the shutdown animation comprises the first sub-animation or the shutdown animation comprises the first sub-animation and the second sub-animation, a plurality of calculation modes of the remaining time are provided. The following describes an implementation of calculating the remaining time with reference to the specific drawings.
Fig. 11 is a flowchart of a remaining time calculation method provided according to a possible embodiment, the method being applied to the display device shown in the above embodiment, wherein the controller is further configured to perform S111 to S113:
in S111, the total number of frames is read in response to the shutdown instruction.
In this embodiment, the total frame number is the number of frame pictures included in the shutdown animation, and the frame pictures include a first frame picture and a second frame picture; the total number of frames may be stored in the memory in advance. In response to a shutdown command, the controller retrieves a total number of frames in the memory.
In S112, the second display starts to play the first sub-animation, and subtracts the current frame number from the total frame number at each preset interval time to obtain a remaining frame number, where the current frame number is a frame number corresponding to a frame picture currently displayed by the second display;
the specific implementation mode can be as follows: the controller stores in advance the number of first frame pictures and the number of second frame pictures included in the shutdown animation. In response to the shutdown instruction, the controller starts counting the number of already played frame pictures, and when the number of already played frame pictures is equal to the number of second frame pictures, the controller counts a remaining number of frames at intervals of a preset time.
The specific implementation mode can be as follows: the first frame image and the second frame image carry different identifications, the controller reads the identifications in real time, and when the identification of the first frame image is read, the controller calculates a residual frame number at preset intervals.
In S113, the remaining playing time is calculated from the remaining number of frames and the presentation time of the frame picture.
Specifically, the controller stores the number of first frame pictures (Size1), the number of second frame pictures (Size2), and the Presentation Time (PT) of the frame pictures in advance. The controller may calculate the total play-out time period T according to the following formula: total T ═ PT (Size1+ Size 2).
The remaining play duration LeftTime is T-PT (Size1+ Size2-Size current). Size is currently the current frame number.
Fig. 12 is a flowchart of a remaining time calculation method provided according to a possible embodiment, the method being applied to the display device shown in the above embodiment, wherein the controller is further configured to perform S121 to S123:
in S121, in response to a shutdown instruction, reading a total playing time of the shutdown animation;
the specific implementation mode can be as follows: the controller prestores the total time length of the shutdown animation, wherein the total time length comprises the playing time length of the first sub-animation and the playing time length of the second sub-animation.
In S122, the second display starts to play the first sub-animation, and reads a current playing time at intervals of a preset time, where the current playing time takes the time of receiving the shutdown instruction as a starting point;
the controller may read the current playing time at intervals of a preset time, starting from the time when the playing time of the shutdown animation is equal to the playing time of the second sub-animation. In this embodiment, the current playing time is a time starting from the time when the shutdown instruction is received.
In S123, the current playing time is subtracted from the total playing time to obtain the remaining playing time.
It should be noted that, this embodiment merely describes two remaining playing time calculation manners by way of example, and in the process of practical application, the remaining playing time calculation manners may be, but are not limited to, the two manners described above, and the applicant does not make much limitation herein.
As a feasible implementation, the display screen is embedded with a camera; the camera is arranged below the second display.
In this embodiment, the camera is used for collecting images. As a possible embodiment, the camera may include a front camera and a rear camera, wherein the front camera may collect an image located in front of the first display, and the rear camera may collect an image located behind the first display. The controller may determine whether to capture an image with the front-facing camera or the rear-facing camera based on the currently launched application. The display equipment shown in the embodiment can meet the requirement that a user acquires images by using the display equipment, and the user experience is good.
In general, in order to achieve the purpose of rational utilization of space, the camera is set to be a liftable camera in the embodiment, and when the camera needs to be used for collecting images, the camera is controlled to be lifted to achieve the purpose of image collection; when the camera is not needed to be used for collecting images, the camera is controlled to be folded to achieve the purpose of reasonably utilizing the space. Therefore, the position of the camera (whether the camera is located above or behind the first display) cannot be known when the device is turned off. The camera is located above the first display or behind the first display, and certain influence is generated on the screen reduction speed of the display screen in the shutdown process.
In order to ensure that the shutdown animation bundle is played, the driving component drives the display screen to descend to the rear of the first display. In this embodiment, a method for controlling the descending of the display screen during the shutdown process is further optimized, specifically referring to fig. 13, where fig. 13 is a flowchart of a method for controlling the descending of the display screen according to a feasible embodiment, and the flowchart may be applied to the display device shown in the foregoing embodiment, where the improvement point is that the controller is further configured to execute steps S131 to S132:
in S131, reading a position of the camera in response to a shutdown instruction;
there are various ways to read the position of the camera.
For example: as a possible implementation, the controller is configured to perform steps (11) to (13): step (11) reading the first height; in this embodiment, the first height is a height of the bottom end of the camera, and the first height is a relative numerical value, and this embodiment does not limit the reference point, and the first height may use the height of the bottom end of the display device as the reference point, and may also use other heights as the reference point. If the first height is not less than the second height, step (12) determines that the camera is above the first display; in this embodiment, the second height is a height of the top end of the first display, and the second height is a relative value. And if the first height is not less than the second height, the camera is positioned above the first display. If the first height is less than the second height, step (13) determines that the camera is obscured by the first display. And if the first height is smaller than the second height, the camera is positioned behind the first display.
For another example: as a possible implementation, the controller is configured to perform steps (21) to (23): reading an identification position of the camera lifting switch; in this embodiment, can dispose camera lifting switch for the camera, work as camera lifting switch is in the on-state, and the camera is located the higher authority of first display, and camera lifting switch's sign position is first sign position this moment. When the camera lifting switch is in a closed state, the camera is positioned behind the first display, and the identification position of the camera lifting switch is the second identification position. Therefore, the controller can determine the position of the camera by reading the identification bit of the camera lifting switch. If the identification bit is a first identification bit, step (22) determines that the camera is positioned on the upper side of the first display; and (23) if the identification bit is the second identification bit, determining that the camera is positioned behind the first display.
It should be noted that the present embodiment merely describes two implementation manners of reading the position of the camera by way of example, and in the process of practical application, the implementation manner of reading the position of the camera may be, but is not limited to, the two implementation manners described above, which is not limited by the applicant herein.
In S132, if the camera is located above the first display, the driving assembly is controlled to drive the display screen to descend to a preset position.
In this embodiment, when the display screen descends to a preset position, the second display is located above the first display, and the camera is located behind the first display; the time for the camera to descend from the upper side of the first display to the back side of the first display is less than or equal to the playing time of the second sub-animation.
The control process described above is described below with reference to specific examples.
In S133, if the camera is located behind the first display, the driving component does not drive the display screen to descend before the second display plays the first sub-animation.
