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 first display can be controlled to display the shutdown animation in the shutdown process. Specifically, during the shutdown process, the first 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.

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 display screen cannot be seen.
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 first display to play shutdown animation;
in the application, the shutdown instruction can be triggered by a user, and the user can trigger the shutdown instruction in various ways. 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 playing time of the shutdown animation and the height of the display screen leaking out of the first display;
in this application, the height that the display screen leaks out first display is a relative numerical value, and it can be specifically the difference of the height at display screen top and the height at first display top. In this application, the height on first display top is a definite value, and consequently, the controller only need read the height on display screen top, then subtracts the height on first display top with the height on display screen top alright know the height that the display screen spills 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 display screen leaking out of the first display is the height difference between the top of the display screen and the top of the first display.
In the application, the playing time of the shutdown animation can be stored in the controller in advance, or stored in the cloud server in advance. In response to the shutdown instruction, the controller may directly call the playing time of the shutdown animation.
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.
It can be seen that in the display device shown in this embodiment, in the shutdown process, the controller controls the first display to play the shutdown animation, and controls the driving component to drive the display screen to descend, where the display screen descends according to the screen descending speed. Because, the speed of falling the screen is correlated with the broadcast time of shutdown animation and the height that the display screen spills first display, and then can guarantee when shutdown animation restraints the broadcast, drive assembly drives the display screen descends to the rear of first display, and user experience feels better.
In the process of practical application, in order to further improve the synchronization between the playing process of the shutdown animation and the descending process of the display screen, the controller may recalculate a screen descending speed after the shutdown animation is played for a preset time. Then, the controller adjusts the descending speed of the display screen based on the recalculated descending speed so as to improve the synchronism of the shutdown animation playing process and the descending process 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-S74:
in S71, when the shutdown animation is played for a preset time, the height of the display screen leaking out of the first display is read.
In this application, the preset time is a time less than the playing time, for example, in some feasible embodiments, the preset time may be half of the playing time; for another example, in some feasible embodiments the preset time may be one third of the play time.
The implementation of reading the height of the display screen leaking out of the first display can refer to the above embodiments, and details are not repeated by the applicant herein.
In S72, a first remaining time is calculated according to the height at which the display screen leaks out of the first display and the screen dropping speed, and a second remaining time is calculated according to the playback time and the preset time.
In the present application, LT1(LeftTime1, first remaining time) can be calculated by the following formula: LeftTime1 is LH/Speed, where LH (leftright, the height of the display screen from the first display) and Speed is the screen reduction Speed.
In the present application, LT2(LeftTime2, second remaining time) can be calculated by the following formula: LeftTime2 is preset to TS-T, where TS is the playing time of the shutdown animation and T is preset to a preset time.
In S73, calculating a difference between the first remaining time and the second remaining;
in S74, if the difference is not within a preset range, adjusting the screen reduction speed according to the second remaining time.
The preset range is not limited in this embodiment, and can be set as required, for example, in some feasible embodiments, the preset range may be { -2s to +2s }.
The screen dropping speed after adjustment is as follows: LH/LT 2. The controller can control the driving assembly to drive the display to descend according to the adjusted screen descending speed.
In this embodiment, when the shutdown animation is played to the preset time, the controller may recalculate a screen reduction speed. Then, the controller adjusts the falling speed of the display screen based on the recalculated falling speed. According to the technical scheme, even if the playing process of the shutdown animation is not synchronous with the descending process of the display screen in the shutdown process, the controller can adjust the descending process of the display screen according to the recalculated descending speed of the display screen, so that the playing process of the shutdown animation is synchronous with the descending process of the display screen.
In the process of practical application, in order to further improve the synchronization between the playing process of the shutdown animation and the descending process of the display screen, after the shutdown animation is played to the preset time, the controller may determine whether to adjust the playing process of the shutdown animation according to the playing condition of the shutdown animation in combination with the descending condition of the display screen. To explain the above process with reference to the specific drawings, fig. 8 is a flowchart of a shutdown animation adjustment 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: S81-S84:
in S81, when the shutdown animation is played for a preset time, the height of the display screen leaking out of the first display is read.
In this application, the preset time is a time less than the play time.
In S82, calculating a first remaining time according to the height of the display screen leaking out of the first display and the screen dropping speed, and calculating a second remaining time according to the playing time and the preset time;
the manner of calculating the first remaining time and the second remaining time may refer to the above embodiments, and is not described herein again.
In S83, calculating a difference between the first remaining time and the second remaining;
in S84, if the difference is not within the preset range, controlling the first display to complete the playing of the remaining shutdown animation within the first remaining time.
The implementation process of controlling the first display to complete the playing of the remaining shutdown animation within the first remaining time may be: and adjusting the display time of a frame picture contained in the shutdown animation according to the first remaining time.
Fig. 9 is a flowchart of adjusting a shutdown animation playing process according to the first remaining time according to a feasible embodiment, where the controller is further configured to perform: S91-S94:
in S91, in response to a shutdown instruction, counting the number of frames of a currently displayed frame picture of the first display;
in the application, the controller counts the frame number of the current display frame picture in real time; the specific statistical process may be, but is not limited to, increasing the number of frames by 1 for each frame of the shutdown animation displayed on the first display.
In S92, if the difference is not within the preset range, subtracting the total number of frames of the shutdown animation including frames from the number of frames of the currently displayed frame to obtain the remaining number of frames;
in the application, the total frame number of the shutdown animation including the frame picture may be pre-stored in the controller, or pre-stored in the cloud server. In response to the shutdown instruction, the controller may directly call the total number of frames of the shutdown animation including the frame picture.
For example, in a feasible embodiment, the total frame number of the shutdown animation including the frame pictures is 1000, and the frame number of the currently displayed frame picture is 500, then the remaining frame number is equal to 1000 and 500.
In S93, calculating an adjusted frame display time based on the first remaining time and the remaining number of frames;
in the present application, the adjusted frame display time (NST adjustment) can be calculated by using the following formula: NST adjust LT 1/remaining frame number.
In S94, the first display is controlled to continue playing the shutdown animation according to the adjusted frame display time.
In this application, after the controller calculates the adjusted frame display time, the controller adjusts the display time of each non-displayed frame to NST adjustment.
In the application, when the shutdown animation is played to the preset time, the controller can determine whether to adjust the playing process of the shutdown animation according to the playing condition of the shutdown animation and the descending condition of the display screen. If the adjustment is needed, calculating the adjusted frame picture display time according to the first remaining time and the remaining frame number, and controlling the first display to continuously play the shutdown animation according to the adjusted frame picture display time. According to the technical scheme, even if the playing process of the shutdown animation is not synchronous with the descending process of the display screen in the shutdown process, the controller can adjust the playing process of the shutdown animation according to the adjusted frame picture display time so as to ensure that the playing process of the shutdown animation is synchronous with the descending process of the display screen.
In the process of practical application, in order to further improve the synchronization between the playing process of the shutdown animation and the descending process of the display screen, when the first display displays the last frame of the shutdown animation, the controller may determine whether to adjust the playing process of the shutdown animation according to the playing condition of the shutdown animation in combination with the descending condition of the display screen. To explain the above process with reference to the specific drawings, fig. 10 is a flowchart of a shutdown animation adjustment 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: s101 to S103:
in S101, when the current display frame is the last frame, calculating a first remaining time according to the height of the display screen leaking out of the first display and the screen dropping speed;
in the application, the total frame number of the shutdown animation including the frame picture may be pre-stored in the controller, or pre-stored in the cloud server. In response to the shutdown instruction, the controller may directly call the total number of frames of the shutdown animation including the frame picture. The controller reads the frame number of the current display frame picture of the first display in real time, and when the frame number is equal to the total frame number, the previous display frame picture is the last frame picture.
The implementation of calculating the first remaining time according to the height of the display screen leaking out of the first display and the screen dropping speed may refer to the above embodiments, and is not described herein again.
In S102, if the first remaining time is less than or equal to the adjusted frame display time, controlling the first display to end the playing of the shutdown animation;
in this application, if the first remaining time is less than the adjusted frame display time, it is proved that the descending speed of the display screen is fast, and the controller controls the first display to end the playing of the shutdown animation.
In this application, if the first remaining time is equal to the adjusted frame display time, it is proved that the descending speed of the display screen is matched with the playing speed of the shutdown animation, and the controller controls the first display to end the playing of the shutdown animation.
In S103, if the first remaining time is greater than the adjusted frame display time, controlling the first display to continue displaying the last frame, where the continuing display time of the last frame is related to the first remaining time and the adjusted frame display time.
In the application, if the first remaining time is greater than the adjusted frame display time, it proves that the descending speed of the display screen is slow. In this case, the controller controls the first display to extend the presentation time of the last frame picture. As a possibility. The extension time of the last frame picture may be equal to the difference between the first remaining time and the adjusted presentation time of the frame picture.
In the application, when the last frame is played, the controller determines whether to adjust the playing process of the shutdown animation according to the playing condition of the shutdown animation and the descending condition of the display screen. The descending speed of the display screen is slow, and the controller can control the first display to prolong the display time of the last frame of picture. According to the technical scheme, even if the playing process of the shutdown animation is not synchronous with the descending process of the display screen in the shutdown process, the controller can adjust the playing process of the shutdown animation according to the adjusted frame picture display time so as to ensure that the playing process of the shutdown animation is synchronous with the descending process of the display screen.
As a feasible implementation, the controller includes: a first sub-controller (which may also be referred to as a first controller in this embodiment) and a second sub-controller (which may also be referred to as a second controller in this embodiment). The operation of the display device is described below with reference to the following specific drawings: fig. 11 is a flowchart illustrating interaction among components of a display device according to a possible embodiment.
And the first sub-controller executes the step S111, and sends a message carrying the play time to the second sub-controller in response to the shutdown instruction.
The second sub-controller executes step S112, and in response to receiving the message with the playing time, calculates the screen dropping speed according to the playing time and the height of the display screen leaking out of the first display;
the second sub-controller performs step S113 to send a feedback message to the first controller.
And the first sub-controller executes the step S114, calculates a delay time if receiving the feedback message sent by the second controller, and sends a screen-down instruction to the second controller.
In the present application, the delay time is equal to half of the message transfer time, and the message transfer time takes the time corresponding to the transmission of the message carrying the play time as a starting point and the time corresponding to the reception of the feedback message as an end point. Specifically, the delay time ET may be calculated according to the following formula: and ET is (T2-T1)/2, where T2 is a time corresponding to the first sub-controller receiving the feedback message, and T1 is a time corresponding to the first sub-controller sending the message carrying the play time.
The second sub-controller executes the step S115, responds to the screen descending instruction, and controls the driving assembly to drive the display screen to descend according to the screen descending speed;
and the first sub-controller executes the step S116, and controls the first display to play the shutdown animation after delaying time after sending the screen reduction instruction.
The display device shown in this embodiment controls the first display to play the shutdown animation after the delay time elapses after the screen down instruction is sent, so that the playing of the shutdown animation and the lowering of the display screen are performed simultaneously, and the playing process of the shutdown animation and the lowering process of the display screen are ensured to be synchronous.
In order to further improve the synchronization between the playing process of the shutdown animation and the descending process of the display screen, as a feasible implementation manner, when the shutdown animation is played to the preset time, the first sub-controller sends a message R3 to the second sub-controller. The second sub-controller, having received R3, calculates a first remaining time LT 1. The second sub-controller determines whether the screen down process and the shutdown animation playback process are synchronized based on LT1, and the determination process will be described with reference to specific examples.
In a possible embodiment, the preset time is equal to half the play time (ST). When the shutdown animation is played to ST/2, the first sub-controller sends a message R3 to the second sub-controller. The second sub-controller receives R3 and calculates LT 1. In the present application, the variation between the difference { -A- + A } of LT1 and ST/2 is allowed, that is, the second sub-controller judges whether LT1 satisfies the range: (ST/2) -a < ═ LT1+ ET < ═ (ST/2) + a, where ET is the delay time: ET is (T2-T1)/2. If LT1+ ET is greater than (ST/2) + A, then the playback speed of the shutdown animation is fast: the second controller calculates a correction time CT, LT1+ ET- (ST/2); if LT1+ ET is less than (ST/2) -A, the descending speed of the display screen is fast, and the second controller calculates a correction time CT which is ST/2- (LT1+ ET); if LT1+ ET is greater than (ST/2) + A or if LT1+ ET is less than (ST/2) -A, the second sub-controller sends a message S2 to the first sub-controller carrying CT.
The first sub-controller receives S2, calculates the adjusted frame display time NST adjustment according to the CT value: specifically, if LT1+ ET is greater than (ST/2) + a, to synchronize the descending process of the display screen with the playing process of the shutdown animation, after the first sub-controller receives S2, it needs to play the remaining frame pictures in the LT1-ST/2 time period, that is, the adjusted frame picture display time NST is adjusted to (LT 1-ST/2)/the remaining frame number, that is, NST is adjusted to (CT-ET)/the remaining frame number. If LT1+ ET is smaller than (ST/2) -a, in order to synchronize the descending process of the display screen with the playing process of the shutdown animation, after the first sub-controller receives S2, it needs to play the remaining frame pictures in the LT1-ST/2 time period, that is, the adjusted frame picture display time NST is adjusted to (LT 1-ST/2)/the remaining frame number, that is, NST is adjusted to (ET-CT)/the remaining frame number.
In order to further improve the synchronization between the playing process of the shutdown animation and the descending process of the display screen, as a feasible implementation manner, when the shutdown animation is played to the last frame of picture, the first sub-controller sends a message R4 to the second sub-controller. The second sub-controller, having received R4, calculates a first remaining time LT 1. The second sub-controller judges whether the display screen falling process and the shutdown animation playing process are synchronized based on LT 1. The above determination process is described below with reference to specific examples.
In a possible embodiment, the first sub-controller sends a message R4 to the second sub-controller when the animation is played to the last frame of the frame. The second sub-controller receives R4 and calculates LT 1. In the present application, the second sub-controller determines whether LT1 satisfies the following range: NST adjustment LT1+ ET NST adjustment + ET, where ET is the delay time: ET is (T2-T1)/2. If LT1+ ET is greater than NST + ET, the second sub-controller sends a notification to the first sub-controller, wherein the notification is used for guiding the first sub-controller to continue displaying the last picture (LT-NST) and then ending playing the shutdown animation. If LT1+ ET is less than the NST adjustment, the second sub-controller sends a notification to the first sub-controller instructing the first sub-controller to end playing the shutdown animation.
