In some embodiments, the second display device of the display apparatus may be disposed behind the first display device after the display apparatus is turned off, and then the second display device needs to be moved from a position behind the first display device as shown in fig. 3 to a position of a preset height of the first display device as shown in fig. 2 after the display apparatus is turned on. For example, the second display device may be lifted by controlling a driving device such as a motor.

In some embodiments, the second display device may begin to rise 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 rise after receiving the instruction, and the instruction may be a control signal sent by the first display device to the second display device. The two lifting timings of the second display device will be described with reference to fig. 13 to 14 and fig. 15 to 16, respectively.

In some embodiments, fig. 13 is a flowchart of an embodiment of a control method of a display device provided in the present application, where a flowchart of a second display device of the display device may start to be lifted after being powered on is shown. In the flow chart corresponding to the second display device on the right side, the second display device starts to rise after being powered on, and then operations such as kernel starting (logo displaying) and init initializing can be performed, and the second display device is kept on the displayed logo page to wait for receiving the control signal sent by the first display device. And after receiving the control signal, starting to play the startup animation.

Referring to fig. 14, fig. 14 is a schematic display diagram of a display device provided in the present application, and shows a schematic display diagram of a flow shown in fig. 13, and before the display device is powered on, in a state a in fig. 14, a second display apparatus (201, small screen) is hidden behind a first display apparatus (260, large screen). When the first display device and the second display device are powered on at the same time, in state B of fig. 14, the second display device starts to rise, and at the same time, the two display decorative covers each display different contents, for example, a startup LOGO, and in fig. 14, the graphic 2011 displayed by the second display device 201 is denoted as a third content, and the graphic 2001 displayed by the first display device 260 is denoted as a fourth content. At this time, since the second display device is still in the rising state, the user can see the process in which the second display device 201 rises with the display pattern 2011 in some cases.

Then, since the operating system of the second display device has a smaller calculation amount, after the second display device completes operations such as Kernel start and initialization (init), the second display device waits for an instruction of the first display device. After the first display device completes operations such as Kernel start and initialization (init), a control signal is sent to the second display device by means of RPC communication, so that the second display device plays the startup animation according to the indication of the first display device, corresponding to state C in fig. 14, the first display device 260 plays the startup animation 2002, and the second display device 201 plays the startup animation 2012 according to the indication of the large screen.

Finally, when the startup process of the display device is completed after the startup animation of the first display device and the second display device is played, in state C of fig. 14, the first display device and the second display device display the functional pages 2003 and 2013 of the homepage, the application program, and the like, respectively, so that the user can perform subsequent operations on the functional pages.

In some embodiments, fig. 15 is a flowchart of an embodiment of a control method of a display device provided in the present application, where the flowchart illustrates that a second display device of the display device does not rise immediately after being powered on, but begins to rise after receiving a control signal of a first display device. In the flow chart corresponding to the second display device on the right side, the second display device does not start to rise immediately after being powered on, but keeps on the displayed logo page after operations such as kernel starting (logo displaying) and init initializing can be performed, and starts to play the startup animation according to the control signal after waiting for receiving the control signal sent by the first display device, and starts to rise according to the control signal at the same time.

Referring to fig. 16, fig. 16 is a schematic display diagram of a display device provided in the present application, where the schematic display diagram shows a flow shown in fig. 15, and then, before the display device is powered on, in a state E in fig. 16, a second display apparatus (small screen) is hidden behind a first display apparatus (large screen). When the first display device and the second display device are powered on at the same time, the second display device does not immediately rise in state F of fig. 16, and at the same time, the first display device 260 displays the graphic 2001, and at this time, the second display device may not display the boot graphic or may display it because it is hidden behind the first display device.

Then, since the operating system of the second display device has a smaller calculation amount, after the second display device completes operations such as Kernel start and initialization (init), the second display device waits for an instruction of the first display device. After the first display device completes operations such as Kernel start and initialization (init), a control signal is sent to the second display device by means of RPC communication, so that the second display device starts to rise according to the indication of the first display device, and plays the startup animation, corresponding to state G in fig. 16, the first display device 260 plays the startup animation 2002, and the second display device 201 plays the startup animation 2012 according to the indication of the first display device. At this time, in some cases, the user can see the process in which the second display device 201 rises with the startup animation 2012.

Finally, when the startup process of the display device is completed after the startup animation is played, in state H of fig. 16, the first display device and the second display device each display the functional pages 2003 and 2013 such as the homepage, the application program, etc., so that the user can perform the subsequent operation on the functional pages.

In summary, in the embodiments shown in fig. 15 to fig. 16, compared with the embodiments shown in fig. 13 to fig. 14, after receiving the control signal, the second display device may further determine the start time of playing the startup animation according to the control signal, so as to increase the association between the content played by the two display devices, so that the two startup animations can achieve the playing effect of being "mutually linked" in time, and further improve the viewing experience of the user.

In some embodiments, when the second display device moves from the position behind the first display device shown in fig. 3 to the position of the preset height of the first display device shown in fig. 2, the raised preset height may be adjusted differently according to the setting of the display device. Wherein the preset height may be determined by the second display means by determining preset state information within the display device after power up.

In some embodiments, the preset information includes: first switching information and second switching information. The first switch information is a switch for indicating whether the second display device is lifted, when the first switch information is in an on state, the second switch information is used for indicating that the second display device is required to be moved above the first display device, and when the first switch is in an off state, the first switch information is used for indicating that the second display device is not required to be moved above the first display device.

In some embodiments, the second switch information may be a switch of an image collector of the display device. For example, fig. 17 is a schematic structural diagram of a second display device provided in the present application, where the image collector 202 of the display apparatus may be disposed at any position on the second display device 201, and in fig. 17, taking an example that the image collector 202 is disposed below the second display device 201, the second display device 201 is divided into an upper part and a lower part by a dotted line in fig. 17, the upper part may be used for displaying content, and the lower part may be used for disposing the image collector 202. The distance between the image collector 202 and the upper edge of the second display device 201 is denoted as a first height L1, and the distance between the upper and lower edges of the second display device 201 is denoted as a second height L2. When the second switch information is in the on state, the second switch information is used for indicating that the second display device needs to be lifted to a second height L2 capable of exposing the image collector 202; 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, that is, since the image capture device is not used, the second display device may not expose the image capture device 202.

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 an on state and the second switch information is in an 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 the first switch information is determined to be in an on state and the second switch information is determined to be 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 off state, determining that the preset height is 0.

In some embodiments, fig. 18 is a flowchart of determining a preset height of the display apparatus provided in the present application, where taking a value of the first height L1 as 70 and a value of the second height L2 as 100 as an example, where 100 and 70 may specifically be a percentage of a distance between an upper edge of the second display device and an upper edge of the first display device after the second display device is lifted up to the height of the second display device, where 100, 70, and 0 are only a possible height proportion, may be set to other proportions, or may be other units of height measurement, which may be all the variations of the embodiment, and the final purpose is to differentially control the lifted height of the second display device, which is whether to expose the image capturing apparatus and whether to lift the second display device.

In some embodiments, the second display device may not completely maintain the position as shown in fig. 3 and may be raised by a certain height in some cases due to unexpected situations such as power failure when the display apparatus is turned off last time, so the second display device also needs to determine the current height of the second display device, so as to determine whether to raise or lower the height of 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) through the state of the second switch information, if the state of the second switch information is in the off state, it is determined that the image capturing device is not turned on, then it is further determined that the state of the first switch information is further determined that the height of the second display device needs to be raised to 70, then it is further determined whether the current height of the second display device is 70, if yes, it is not necessary to control the height of the second display device, and then the process is ended, and if not, it is necessary to raise the height of the second display device to 70, and finally the process is ended. When the state of the second switch information is the off state and the state of the first switch information is the off state, determining that the height of the second display device needs to be reduced to 0, then judging whether the current height of the second display device is 0 or not, if so, not controlling the height of the second display device to end the process, and if not, controlling the height of the second display device to be reduced to 0. When the state of the second switch information is the on state, it is determined that the height of the second display device needs to be raised, then it is determined whether the second display device of the display apparatus is raised for the first time, if yes, it is determined that the height of the second display device needs to be raised to 70, and if not, it is determined whether the height of the second display device needs to be raised for the first time, and if not, it is determined that the height of the second display device needs to be 100. And after determining the height of the second display device to be lifted, judging whether the current height of the second display device is the same as the height to be lifted, if so, ending the flow, and otherwise, controlling the second display device to be lifted to the corresponding height.

In some embodiments, in the display apparatus provided in each embodiment of the present application, when the first display device performs a reset operation for restoring factory settings, a first reset screen is displayed, and the second display device may also display an associated second reset screen, so as to implement content linkage of the two display devices. For example, fig. 19 is a schematic display diagram of an embodiment of a display device of the present application, where when a first display device receives an instruction for restoring factory settings and starts a reset operation, a first reset screen may be displayed, where the first reset screen includes a prompt message of "system is being initialized" and an initialized progress bar, etc. At this time, a second reset screen may be displayed on the second display device, and the second reset screen may be the same as the first reset screen.

Alternatively, in some embodiments, fig. 20 is a schematic display diagram of an embodiment of a display device of the present application, where in the display device shown in fig. 20, the second display device may display an initialized progress bar.

In fig. 19 and 20, the first display device and the second display device may be linked by RPC communication. For example, when the first display device performs factory setting to perform a reset operation and displays the first reset screen, a control signal is sent to the second display device, so that after the second display device receives the control signal, the second display device displays the corresponding second reset screen by the control signal. The second reset image content displayed by the second display device may be stored in advance or transmitted to the second display device by the first display device.

In some embodiments, the scene as shown in fig. 19-20 may also be other scenes in which the function settings of the display device are made, and the second display device may display all or part of the associated function setting content when the first display device displays the content of one function setting.

In some embodiments, after the first display device completes the reset operation, it is determined whether the second display device also completes the reset operation, and the control of the first display device and the reset operation command of the second display device may be controlled by one overall controller or may be controlled by two controllers respectively. After the first display device and the second display device are reset, the first display device and the second display device enter initialization operation respectively, and an initialization interface is displayed respectively; if the first display device completes the reset operation, but detects that the second display device is not completed, the first display device waits for the second display device to complete, and then executes the following steps.

In some embodiments, the second display device may be used as a basis for determining whether the first display device is completed after the second display device completes the reset operation, and if not, after waiting for the completion of the first display device, the two display devices each enter the initialization operation, and specifically are not expanded.

In some embodiments, after the first display device displays the first initialization screen, determining whether the second display device completes the initialization operation by a polling method; and stopping displaying the first initialization picture by the first display device if the first display device and the second display device finish the initialization operation.

In some embodiments, after the second display device displays the second initialization screen, it is also determined whether the first display device completes the initialization operation by a polling method; and stopping displaying the first initialization picture by the second display device after the first display device and the second display device finish the initialization operation.

Through the mode, the interaction between the two display devices can be enabled to look like a display device which is in reset, initialization and other operations.

In some embodiments, in the foregoing resetting operation of the display device, after the resetting operation is performed, the system is initialized by the first display device and the second display device, and after the initialization is completed, the first display device and the second display device enter the main system, once one display device is abnormal in the initialization process, the first display device and the second display device cannot enter the main system, and therefore, the initialization fails, and other abnormalities occur in the display device.

In some embodiments, taking the first display device in fig. 21 as an example, the first display device may continue to wait for the second display device to complete the initialization operation (the initialization progress reaches 100%) after completing the initialization operation (the initialization progress reaches 100%), and the first display device may stop displaying the first initialization screen and enter the main system after determining that both the first display device and the second display device complete the initialization operation. Similarly, after the second display device completes the initialization operation, the second display device may continue to wait for the first display device to complete the initialization operation, and after determining that both the first display device and the second display device complete the initialization operation, the second display device may stop displaying the second initialization screen and enter the host system.

In some embodiments, the first display device and the second display device may determine whether the initialization operation is completed by the counterpart in a manner of polling once per minute. And once the progress of the opposite party is monitored to be unchanged within the preset time, judging that the opposite party is abnormal in initialization, and restarting the initialization operation, and sending a restarting instruction to the opposite party, so that the opposite party display device also restarts the initialization operation. The waiting-side display device may maintain a first initialization screen, for example, a screen indicating an initialization progress of 100%, for a preset time.

In some embodiments, taking the first display device in fig. 21 as an example, when the first display device completes the initialization operation and determines that the progress of the second display device for 2 minutes has not changed during the polling process, and continues to wait for 10 minutes, and then, the first display device sends a restart instruction to the second display device, so that the second display device performs the restart operation again, and the first display device may also perform the restart operation again. Similarly, when the second display device completes the initialization operation and determines that the progress of the first display device for 2 minutes has not changed and continues to wait for 10 minutes, and then the second display device sends a restart instruction to the first display device, so that the first display device can restart the operation, and the second display device can restart the operation.

The preset time of the first display device may be a first preset time, and the preset time of the second display device may be a second preset time.

In some embodiments, the present application further provides a control method, configured to, in the above display apparatus, control the first display device to display a first reset screen and control the second display device to display a second reset screen when the first display device receives a reset instruction; wherein the second reset screen includes a part of or the whole of the content in the first reset screen. Reference is made to the foregoing for additional specific steps, which are not repeated here.
