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 should be noted that, after the camera is turned on in the technical solution shown in this embodiment, the camera does not leak out of the first display, that is, the camera is still disposed behind the first display, and only when the first application (which will be described later with reference to the first application) is in the 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 general, in order to achieve the purpose of rational utilization of space, some display devices set a camera as a liftable camera, and control the camera to rise to achieve the purpose of image acquisition when the camera is required to acquire images; 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. How to reasonably control the 'lifting' and 'retracting' of the camera becomes a technical problem to be solved urgently.
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 device comprises a controller, a first display and a display screen, wherein the display screen at least comprises a camera. The operation of the display device is described below with reference to the following specific drawings:
