Then, when the second display device receives the control information, for example, when the identification information of the first content is "1", the content 1 may be played as the second content according to the mapping relationship shown in fig. 12. It is understood that the contents 1 to N may be stored in the second display apparatus in advance together with the mapping relationship. Moreover, the mapping relationship and the content can be changed by a user of the display device, or the display device obtains the update through the internet.
In some embodiments, the second display device of the display apparatus may be disposed behind the first display device after being powered off, and then when the display apparatus is powered on, the second display device needs to be moved from the position behind the first display device as shown in fig. 3 to the position with the preset height of the first display device as shown in fig. 2. For example, the second display device may be raised by controlling a driving device such as a motor.
In some embodiments, the second display device may begin to be raised upon power-up; alternatively, the second display device may not be raised immediately after power-up, but may start to be raised under the control of the first display device. For example, the first display device may send an instruction to the second display device, and the second display device starts to ascend after receiving the instruction, where the instruction may be a control signal sent by the first display device to the second display device. The two raising timings of the second display device will be described with reference to fig. 13 to 14 and fig. 15 to 16.
In some embodiments, fig. 13 is a flowchart illustrating an embodiment of a method for controlling a display device provided in the present application, wherein the flowchart illustrates that a second display device of the display device may start to lift after being powered on.

In some embodiments, the second switch information may be a switch of an image collector of the display device. Fig. 17 is a schematic structural diagram of a second display apparatus provided in this application, where an image collector 202 of a display device may be disposed at any position on the second display apparatus 201, and in fig. 17, the image collector 202 is disposed under the second display apparatus 201 as an example, then as shown in fig. 17, a dotted line divides the second display apparatus 201 into an upper portion and a lower portion, the upper portion may be used for displaying content, and the lower portion may be used for disposing the image collector 202. The distance between the image pickup device 202 and the upper edge of the second display device 201 is referred to as a first height L1, and the distance between the upper and lower edges of the second display device 201 is referred to as a second height L2. When the second switch information is in an on state, the second switch information is used for indicating that the second display device needs to be lifted to a second height L2 at which the image collector 202 can be exposed; when the second switch information is in the off state, it indicates that the second display device may be raised to the first height L1, i.e., the image collector 202 may not be exposed by the second display device since the image collector is not used.
In some embodiments, in combination with the first switch information and the second switch information, when the second display device determines that the first switch information is in the on state and the second switch information is in the on state, the second display device may determine that the preset height is a second height L2 between the upper edge and the lower edge of the second display device; when it is determined that the first switch information is in an on state and the second switch information is in an off state, determining that the preset height is a first height L1; and when the first switch information is determined to be in the closed state, determining that the preset height is 0.
In some embodiments, fig. 18 is a flowchart of determining the preset height of the display device provided in the present application, where a value of the first height L1 is 70, and a value of the second height L2 is 100 as an example, where 100 and 70 may specifically be percentages of a distance between an upper edge of the second display device and an upper edge of the first display device in a height of the second display device after the second display device is lifted, and the above 100, 70 and 0 are only one possible height ratio setting, and may also be set to other ratios, or other measurements of height by unit may be used as variations of this embodiment, and a final purpose of the present invention is to perform differential control on a height of the second display device lifted, where the difference is whether the image capturing device is exposed, and whether the second display device is lifted.
In some embodiments, when the display apparatus is powered off last time, the second display device may not fully maintain the position shown in fig. 3 in some cases due to an unexpected situation such as power failure, and may be raised by a certain height, and therefore, the second display device further needs to determine the current height of the second display device, so as to determine whether to raise or lower the second display device. As shown in fig. 18, after the second display device is powered on, it may be determined whether to turn on the image capturing device (for example, a camera or the like) according to a state of the second switch information, if the state of the second switch information is an off state, it is determined that the image capturing device is not turned on, then the state of the first switch information is further determined, and it is determined that the height of the second display device needs to be increased to 70 when the state of the first switch information is an on state, and then it is determined whether the current height of the second display device needs to be determined whether the current height of the second display device is 70, if so, the height of the second display device does not need to be controlled to end the process, otherwise, the height of the second display device needs to be increased to 70, and the process is finally ended. When the state of the second switch information is an off state and the state of the first switch information is an off state, determining that the height of the second display device needs to be reduced to 0, and then judging whether the current height of the second display device is 0 or not, if so, controlling the height of the second display device is not needed to finish the process, otherwise, controlling the height of the second display device to reduce the height of the second display device to 0. When the state of the second switch information is an on state, it is determined that the height of the second display device needs to be increased, and then it is determined whether the second display device of the display apparatus is first increased, if so, it is determined that the height of the second display device needs to be increased to 70, and if not, it is determined whether the height of the second display device needs to be increased to 100. And after determining the height for lifting the second display device, judging whether the current height of the second display device is the same as the height to be lifted, if so, ending the process, and if not, controlling the second display device to be lifted to the corresponding height.
