The first controller 210 executes various software programs in the memory 290 such as: image control function, display control function, audio control function, external instruction recognition function, communication control function, optical signal receiving function, power control function, software control platform supporting various functions, browser function and other various functions.
For example, since the image receiving device such as a camera is connected to the controller, the external command recognition module 3907 of the controller may include a graphic recognition module 2907-1, where a graphic database is stored in the graphic recognition module 3907-1, and when the camera receives an external graphic command, the camera performs a correspondence with the command in the graphic database to perform command control on the display device. Since the voice receiving device and the remote controller are connected with the controller, the external command recognition module 2907 of the controller may include a voice recognition module 2907-2, where a voice database is stored in the voice recognition module 2907-2, and when the voice receiving device receives an external voice command or when the voice receiving device receives an external voice command, the voice receiving device and the like perform a corresponding relationship with the command in the voice database, so as to perform command control on the display device. Similarly, the control device 100 such as a remote controller is connected to the controller, and the key instruction recognition module 2907-3 performs instruction interaction with the control device 100.
The foregoing schematic structural diagrams of the display device provided by the present application are shown in fig. 1 to 7, and the display device provided by the present application is merely illustrative, and the display device provided by the present application may be the display device described in fig. 1 to 7, or may be other types of display devices, and is not limited thereto.
Meanwhile, in some split display devices, taking a television as an example, in order to meet the watching requirement of users on vertical screen contents shot by a mobile phone, the display screen of the split television can be rotated. For example, fig. 8 is a schematic structural diagram of an embodiment of a display device according to the present application, where the display device shown in fig. 8 may be a display device as described in any one of fig. 1 to 7, or may be other display devices not shown in fig. 1 to 7. Specifically, the display device provided in this embodiment includes: a host unit 1 and a display screen 2, wherein the display screen 2 is provided outside the host unit 1, and is provided separately from the host unit 1, that is, the host unit 1 and the display screen 2 are provided independently of each other, realizing a display device having a separate display screen. The host unit 1 includes a first processor 11, the first processor 11 may be disposed on a motherboard within the host unit 1, the display screen 2 includes a second processor 21, and the second processor 21 may be disposed on a motherboard within the display screen 2. The first processor 11 and the second processor 21 may be a central processing unit (central processing unit, abbreviated as CPU), a graphic processor (Graphics Processing Unit, abbreviated as GPU), a micro control unit ((Microcontroller Unit, abbreviated as MCU), a System-on-a-Chip (abbreviated as SOC), etc., the host unit 1 and the display screen 2 are connected by a connection line 3, the connection line 3 may be a HI-LINK connection line, the host unit 1 may energize the display screen 2 through the connection line 3, send an optical signal of a picture to be displayed to the display screen 2, and send a control signal lamp to the display screen 2.
In particular, the display device in this embodiment further includes a rotating device 22 on the display screen 2 side, where the rotating device may be a driving device such as a motor, a dc motor, or the like, and may be used to drive rotation to provide an acting force for rotating the display screen 2, so as to drive the display screen 2 to rotate in a display plane, and rotate the display screen 2 to a display state such as a landscape screen state or a portrait screen state. For example, fig. 9 is a schematic structural diagram of a first rotation state of the display device according to the present application, where the rotation device is disposed on a non-display side of the display screen, and the rotation device may drive the display screen to rotate in a display plane thereof. It will be appreciated that the drawing of the rotation device outside the display device as shown in the diagram of fig. 8 is merely illustrative of its structure, and the rotation device may be integrally designed with the display device and considered as a part of the display device. Fig. 10 is a schematic structural diagram of a second rotation state of the display device according to the present application, in which the display screen shown in fig. 9 can rotate in a counterclockwise direction from a horizontal screen state to a vertical screen state as shown in fig. 10 under the driving of the rotation device. It should be noted that, as shown in fig. 9 and fig. 10, the two rotation states are only examples, and the rotation device may also control the display screen to rotate to any other angle.
More specifically, in the display device shown in fig. 8, the first processor 11 on the side of the host unit 1 can instruct the second processor 21 to control the rotation device 22 to rotate by sending an instruction signal to the second processor 21 on the side of the display screen 2. In a specific implementation, the rotating means may be a 12V dc brush motor (simply referred to as motor), and the second processor 21 may then rotate the motor via an H-bridge controlled motor model SGM 42600. The entire control process can be described as: first, the first processor 11 receives an instruction from a user, for example, the user transmits an instruction to instruct the display screen 2 to rotate 90 degrees clockwise to the first processor 11 of the host unit 1 through a remote controller or other means, and the first processor 11 transmits an instruction signal to instruct the display screen 2 to rotate 90 degrees clockwise to the second processor 21 on the display screen 2 side through the connection line 3. Subsequently, after receiving the instruction signal, the second processor 21 may control the motor to select through two signals IN1 and IN2 output to the H-bridge. Illustratively, IN1 and IN2 may each include four cases by a combination of high and low levels, at least for motor driven display screens achieving three motion states: counter-clockwise rotation, stalling, etc. For the H-bridge, control of different states of the motor is achieved by adjusting the two voltages a and B output to the rotating device 24 according to the received rotation control signals IN1 and IN2, so that the motor drives the whole display screen to rotate clockwise, rotate anticlockwise or stop.
In order to enable the first processor 11 in the host unit 1 to determine the current rotation state of the display screen 2, so that the first processor 11 can control the rotation of the display screen according to the current rotation state of the display screen 2, a sensor 23 for detecting the rotation state of the display screen is further disposed in the display screen 2, and the sensor 23 may be specifically two hall magnet sets. The two hall magnet sets can feed back the current rotation state of the rotating device (the state of the rotating device is the same as the rotation state of the display screen) to the second processor 21 through the output H1 and H2 signals after detecting the current rotation state of the rotating device, and the second processor 21 can feed back the current rotation state of the rotating device to the host unit 1 through the connecting wire 3, wherein the rotation state of the display screen at least comprises: 0 degrees, 90 degrees, -90 degrees, 180 degrees, etc.
However, in the split display structure shown in fig. 8 to 10, on the basis that the display screen can be rotated, functions such as control of rotation of the display screen, acquisition of a rotation state and the like are realized, but processing of some possible abnormality such as abnormal power failure is not perfect. For example, fig. 11 is a schematic diagram of a power-on state of a display device, where in case 1A, after the display screen is turned off in a horizontal screen state, when the display screen is turned on again, a power-on display screen such as an icon 201 may be displayed in the horizontal screen state, where the power-on display screen may be an icon of a manufacturer of the display device, an icon of a motherboard, or other static or dynamic images of the power-on start, and is displayed with a (1) th portion of the icon as an upper portion and a (2) th portion as a lower portion; in the case 1B, after the display screen is turned off in the vertical screen state, when the display screen is turned on again, the icon can be displayed in the vertical screen state, and the icon is displayed with the (1) part of the icon as the upper part and the (2) part as the lower part; however, if the display screen is in case 1C, when an abnormal situation such as power-off occurs while the display screen is rotating, it is necessary to determine the current rotation state of the display screen, and then display a start page such as an icon, the specific procedure of which is shown in fig. 12.
Fig. 12 is a schematic diagram of a startup process of a display device in the prior art. In which a process of starting up after power-up of the display device as shown in fig. 8 is shown, it may be performed by the first processor 11 and the second processor 21 in the display device. In the case of the abnormal situation of the case 1C shown in fig. 11, assuming that the display device is powered off abnormally last time and the display device is still rotating when the display device is powered off, after the display device is powered on, a power-on start-up procedure, such as the start-up of the first processor, the second processor, etc., is started at S10. After the first processor and the second processor are started in S10, the second processor executes S11 to start the connected sensor, and after the sensor starts and acquires the state of the display screen, the second processor determines the state of the display screen in S12. Then, the first processor can acquire the current state of the display screen from the second processor through S13, for example, the current rotation state in the case 1C shown in fig. 11, and then the first processor can send an indication signal to the second processor through S14 to instruct the second processor to adjust the rotation state of the display screen, rotate the display screen to the state shown in the case 1A or 1B in fig. 11, finally, the first processor can send a start-up display screen to the second processor in S15 after instructing the second processor to rotate the display screen, and normally display the screen in S16 after the whole display device is started.
In the prior art shown in fig. 12, the starting process is generally performed according to the sequence of the processor and the sensor after the display device is powered on, in this process, the starting process required for the split display device is more complex, wherein the sensor is controlled by the processor after the processor, the first processor needs to wait for the sensor to start and then obtain the rotation state detected by the sensor through the second processor, and then the first processor can send the startup display picture corresponding to the current state of the display device to the second processor to display on the display screen, for example, if the display screen is in a horizontal screen state, the startup display picture sent by the first processor to the second processor is as shown in case 1A of fig. 11, and if the display screen is in a vertical screen state, the startup display picture sent by the first processor to the second processor is as shown in case 1B of fig. 11. Therefore, the split display device shown in fig. 8 requires at least the following flow when handling an abnormality in case 1C shown in fig. 11: the processor starts, the sensor detects the rotation state of the display screen, the sensor feeds back the rotation state of the display screen, the first processor instructs the second processor to adjust the rotation state of the display screen, after all the steps are executed, the display screen is rotated to the horizontal screen state of the case 1A or the vertical screen state of the case 1B as shown in FIG. 11, and then the display of the startup picture can be realized.
Therefore, after the first processor and the second processor are started in S10 and before the first processor sends the power-on display screen to the second processor in S15, the display device will maintain the abnormality of case 1C as shown in fig. 11, and the abnormality of this structure will cause the abnormality of display, so that the display device displays the tilted icon or cannot display the icon. Corresponding to the method shown in fig. 12, after S11 and before S15, since the first processor cannot accurately determine the current rotation state of the display screen, there may be display anomalies, this process may last for several seconds or even tens of seconds, and the startup time of the display device may be prolonged while the anomalies are displayed, so that for the user, the user cannot perceive that the display device is already started in the whole process of S10-S15, and the user experience is greatly affected.
Therefore, how to adjust the rotation state of the display screen more quickly when restarting after the rotatable split display device of the display screen is abnormally powered off, so as to prevent the abnormal display of the starting page such as the icon displayed on the display screen is a technical problem to be solved in the art.
The technical scheme of the application is described in detail below by specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
The application provides a display device control method and a display device, which can be applied to the display device shown in fig. 8, and can adjust the rotation state of a display screen through a second processor arranged in the display screen in the restarting process after abnormal power failure in the rotation process of the display device, so that the rotation state of the display screen is adjusted more quickly after the display device is started, the first processor can send a startup display picture to the second processor more quickly, and display abnormality of startup pages such as icons displayed on the display screen is prevented or display abnormality time is reduced.
Fig. 13 is a flowchart of an embodiment of a control method of a display device according to the present application, where the method shown in fig. 13 may be performed by the display device shown in fig. 8, and the control method of the display device according to the present application is described below with reference to fig. 8 and 13, and includes:
s101: the first processor and the second processor initiate a flow.
In the process of powering on the display device shown in fig. 8, after the display device receives a user' S power-on command, the embodiment starts a power-on process in S101 after powering on the first processor 11 on the host unit 1 side and the second processor on the display screen 2 side in the display device shown in fig. 8. The power required for the second processor 21 to start may be power supplied from the host unit 1 to the display screen 2 through the connection line 3.
S102: the second processor reads the rotation state of the display screen through the register.
Specifically, after the second processor 21 is started, the rotation mark information of the display screen stored in the second processor 21 can be acquired.
Wherein the rotation mark information includes: the rotation state of the display screen 2 and/or the rotation direction of the display screen 2 may be, for example, a current rotation state (a horizontal screen state or a vertical screen state) of the display screen 2 after the display screen 2 is completely rotated by the driving of the rotating device 22, or a rotation state (a rotating state) of the display screen 2 when an abnormality such as a power failure occurs in the incomplete rotation driven by the rotating device 22, and may be a rotation direction when the display screen is not completely rotated when an abnormality such as a power failure occurs in the incomplete rotation driven by the rotating device 22. The above-described rotation mark information may be expressed in the form of different numerical values, and the second processor 21 may record the rotation mark information of the display screen in the form of numerical values through at least one register.
In an exemplary rotatable split display device, as shown in fig. 14, a schematic view of a rotation state of the display device provided by the present application is shown, where the rotation state of the display screen at least includes: a landscape screen state, a portrait screen state, or a rotating state, and a rotation direction when the display screen does not complete rotation includes: clockwise or counterclockwise. When the display screen is in a horizontal screen state, the display screen can rotate to a vertical screen state in a counterclockwise direction under the drive of the rotating device, but when the display screen is abnormal in the state of not rotating to the vertical screen, the rotating state of the display screen is in a rotating state; also, when the display screen is in the portrait state, the display screen may be rotated clockwise to the landscape state by the driving of the rotating device, but when an abnormality occurs in the display screen in the non-rotated landscape state, the rotating state of the display screen is the rotating state at this time.
The second processor can record the rotation direction and rotation state of the display screen through the two registers, respectively. For example, the register a in the second processor may be used to record the rotation direction of the display screen, (e.g., clockwise a=0, counterclockwise a=1), and the register b may be used to record the rotation state of the display screen, which may be represented by the output level of HIN1 or HIN2 of the hall sensor, wherein only HIN2 is detected when the display screen rotates clockwise, and HIN2 is low after the display screen rotates clockwise to the landscape state, where b=0; only HIN1 is detected when the display screen rotates counterclockwise, and HIN1 is at a high level after the display screen rotates counterclockwise to a portrait state, where b=1, and b=f when the display screen is in a rotating state.
Several possibilities of rotation flag information stored in registers a and b are shown in table 1 below:
TABLE 1
In the following description of table 1 with reference to fig. 14 to 16, for example, in the example shown in fig. 14, after the display device is rotated to the landscape state (b=0) by the clockwise direction (a=0), the values of the registers a and b recorded in the second processor are 00; when the display device is rotated to the landscape state (b=1) by the counterclockwise direction (a=1), the values of the registers a and b recorded in the second processor are 00.
Fig. 15 is a schematic view showing a rotation state of the display device according to the present application, in fig. 15, when the display device is driven by the rotation device to rotate clockwise (a=0) from a vertical screen state, b=f during the rotation, if an abnormality such as power failure occurs when the display device is not rotated to a horizontal screen state, the display device will be in an inclined state as shown in fig. 15, and the values of registers a and b recorded in the second processor are 0F; fig. 16 is a schematic diagram of a rotation state of a display device according to the present application, in fig. 16, when the display device is driven by a rotation device to rotate counterclockwise (a=1) from a vertical screen state, b=f during rotation, if an abnormality such as power failure occurs when the display device is not rotated to a horizontal screen state, the display device will be in an inclined state as shown in fig. 16, and the values of registers a and b recorded in the second processor are 1F.
It can be understood that, in this embodiment, the second processor reads the rotation flag information recorded in the at least one register, which is executed during the start-up process. And under the condition of starting up, the first processor sends the indication information to indicate the second processor to rotate the display screen, the second processor can acquire the current rotation state of the display device through the sensor, and the values in the registers a and b are modified according to the rotation state acquired from the sensor in a manner shown in the table 1, so that real-time recording is realized. Thus, the latest updated rotation mark information is recorded in the second processor 21 in real time even if the display device is powered off during the rotation of the display screen.
S103: the second processor controls the rotation device to rotate according to the rotation mark information so as to adjust the rotation state of the display screen.
Specifically, after the second processor reads the rotation flag information of the display screen stored in the register in S102, the rotation state of the display screen may be adjusted according to the rotation flag information, where the rotation of the rotation device is specifically controlled to rotate to drive the display screen to rotate, so as to adjust the rotation state of the display screen.
When the rotation mark information of the display screen read by the second processor is 00 and 11 as shown in fig. 14, the rotation state is in a horizontal screen or vertical screen state because the display screen is not inclined at this time, and the rotation state of the display screen may not be adjusted.
When the rotation flag information of the display screen read by the second processor is 0F as shown in fig. 15, it is indicated that the display screen is in a rotating state and is rotating clockwise but not rotating to a horizontal screen state, the second processor controls the rotating device to drive the display screen to continue rotating in the clockwise direction corresponding to a=0 until the rotation screen is rotated to the horizontal screen state as shown in fig. 15, and then the second processor modifies the rotation flag information in the register to 00.
When the rotation flag information of the display screen read by the second processor is 1F as shown in fig. 16, which indicates that the display screen is in a rotating state and is in a counterclockwise rotation but has not rotated to a portrait state, the display screen is driven by the second processor to continue to rotate in a counterclockwise direction corresponding to a=1 by the rotation means until the rotation screen is rotated to a portrait state as shown in fig. 16, and then the second processor modifies the rotation flag information in the register to 11.
After the second processor adjusts the rotation state of the display screen in S103, the first processor may acquire the rotation state of the display screen from the second processor through S104 and perform the subsequent process. The manner of acquiring the rotation state in S104 is not limited, for example, the first processor may read the value of the register of the rotation flag information in the second processor through the manner of I2C communication or UART communication, or the second processor may send the value of the register for recording the rotation flag information to the first processor through the connection line after S103.
Further, in this embodiment, based on the fact that the time required for the second processor to execute S102-S103 is short, about 1 second, the first processor may execute S105 after the rotation state of the display screen is acquired in S104, and send the startup display screen corresponding to the rotation mark information in S104 to the second processor on one side of the display screen through the connection line, so that the startup display screen is displayed by the display screen. Specifically, the first processor may further send a display icon corresponding to the horizontal screen or a display icon corresponding to the vertical screen to the second processor according to whether the current state of the display device is the horizontal screen state or the vertical screen state. At this time, since the display screen has completed rotating the display screen from the abnormal state to the landscape screen or portrait screen state under the control of the second processor, the display screen is not abnormal in display. In the process, the user only waits for about 1 second, and can see that the display screen rotates to a horizontal screen or vertical screen state, and the display screen displays a startup page after rotating, so that the technical problems that in the prior art, the display of the startup page such as icons displayed on the display screen is abnormal, the time required for recovering the display abnormality is long, and the waiting time of the user is long are solved.
Or in other possible implementation manners, the first processor may directly execute S104 after being started, but since the second processor quickly corrects the abnormality of the display screen through the parallel S102-S103 for about 1 second, the first processor can acquire the normal rotation state and overcome the display abnormality again, so that the time of displaying the abnormality is reduced, the display abnormality can be recovered to be normal only about 1 second, the waiting time of the user is also reduced to a certain extent, and the user experience of the display device is improved.
Alternatively, in the method shown in fig. 13, after the first processor completes the startup through S101, S104 may be continuously performed to acquire rotation flag information recorded by the second processor, and after the rotation state is not the rotating state in the acquired rotation flag information, step S105 may be performed.
It will be understood that after S105, when the display device completes the startup, the whole S101-S105 may be understood as a startup process of the display device, after that, the display device is in a working state, and the first processor may send the display interface of the content to be displayed to the second processor, display the picture by the second processor, etc. in S106 according to a conventional working procedure of the display device, which is not limited by the present application.
Finally, after the display device is abnormally powered off in the rotation process, the second processor on one side of the display screen can control the display screen to rotate according to the recorded rotation mark information directly in the process of restarting the display device through the steps, and the display screen can be controlled to rotate after the processor is started, the sensor is started and interaction is performed by the first processor and the second processor in the prior art as shown in fig. 12 is not needed. Therefore, when the display device provided by the embodiment is started, the second processor replaces the first processor to adjust the rotation state of the display screen, so that the abnormal rotation state of the display screen can be adjusted more quickly, the display screen is adjusted to be in a horizontal screen state or a vertical screen state more quickly, the abnormal display time of the display device is shortened, and the starting time of the second processor can be within 500ms, so that the second processor can adjust the rotation state of the display screen within 1 second after the display device is started, and the user experience is further improved.
Alternatively, the above examples of the rotation state of the display device shown in fig. 14 to 15 may be rotated 90 degrees, which is merely an example for illustrating the method shown in fig. 13, and in other possible implementations, as another example, the display device may be rotated 180 degrees, and the rotation state of the display device may be described with reference to fig. 17 to 20, which will be described below with reference to the accompanying drawings.
Fig. 17 is a schematic diagram of a rotation state of a display device according to the present application, where a display state of a display screen at least includes: a landscape state (e.g., 2A and 3A in the figure), a first portrait state (e.g., 2B in the figure, rotated 90 degrees clockwise from the landscape state), and a second portrait state (e.g., 3B in the figure, rotated 90 degrees counterclockwise from the landscape state), and a rotating state during rotation; and the rotation direction includes: clockwise or counterclockwise. When the display screen does not rotate, at least the states included are: clockwise rotation does not rotate to a first portrait state (e.g., 2C in the figure), clockwise rotation does not rotate to a landscape state (e.g., 3C in the figure), counterclockwise rotation does not rotate to a second portrait state (e.g., 3C in the figure), and counterclockwise rotation does not rotate to a landscape state (e.g., 2C in the figure).
The rotation direction and rotation state of the display screen can be recorded in the second processor through three registers, respectively. For example, the register a in the second processor may be used to record the rotation direction when the display screen rotates, (e.g., clockwise a=0, counterclockwise a=1), the register b and the register c are used to record the rotation state of the display screen, e.g., the register b and the register c may be used to record the output level of HIN1 or HIN2 of the hall sensor, respectively, and several possibilities of the rotation flag information stored in the register a and the register b are shown in table 2 below:
TABLE 2
Rotated counterclockwise by 90 degrees | 0 degree | Clockwise 90 degrees | Other rotation states | |
HIN1 (storing in register b) | 0 | 0 | 1 | 1 |
HIN2 (storing into register c) | 1 | 0 | 0 | 1 |
Referring now to fig. 18-20, for example, fig. 18 is a schematic diagram showing a rotation state of the display device according to the present application, and in the example shown in fig. 18, after the display device is rotated to a landscape state (bc=00) by a clockwise direction (a=0), the values of registers a, b, and c recorded in the second processor are 000; when the display device is rotated to a landscape state (bc=00) by a counterclockwise direction (a=1), the values of the registers a, b, and c recorded in the second processor are 100; when the display device is rotated to the first portrait state (bc=10) by the clockwise direction (a=0), the values of the registers a, b, and c recorded in the second processor are 010; when the display device is rotated to the second portrait state (bc=01) by the counterclockwise direction (a=1), the values of the registers a, b, and c recorded in the second processor are 101. In the embodiment shown in fig. 13, when the rotation mark information of the display screen read by the second processor is 000, 100, 010, or 101 as shown in fig. 18, since the display screen is not tilted at this time and is in the landscape state, the first portrait state, or the second portrait state, it is possible to not adjust the rotation state of the display screen.
Fig. 19 is a schematic diagram of a rotation state of a display device according to the present application, in fig. 19, when the display device is driven by the rotation device to rotate clockwise (a=0) from a horizontal screen state to a first vertical screen state, bc=11 when the display screen is in a rotating state during rotation, if an abnormality such as power failure occurs when the display device is not rotated to the first vertical screen state, the display device will be in a first possible tilt state as shown in the upper part of fig. 19, and the value of a register abc recorded in the second processor is 011. Therefore, when the rotation flag information of the display screen read by the second processor is 011, the second processor controls the rotation means to drive the display screen to continue to rotate in the clockwise direction corresponding to a=0 until the rotation screen is rotated to the first portrait state (010) as shown in the upper part of fig. 19, and then the second processor modifies the rotation flag information in the register to 010.
Also in fig. 19, when the display device is rotated clockwise (a=0) from the second portrait state to the landscape state by the driving of the rotating device, bc=11 when the display screen is in the rotating state during the rotation, if an abnormality such as power failure occurs when the display device is not rotated to the landscape state, the display device sets the value of the register abc recorded in the second processor to 011 in the second possible tilt state as shown in the lower side of fig. 19. Therefore, when the rotation flag information of the display screen read by the second processor is 011, the second processor controls the rotation means to drive the display screen to continue to rotate in the clockwise direction corresponding to a=0 until the rotation screen is rotated to the horizontal screen state (000) as shown in the lower side of fig. 19, and then the second processor modifies the rotation flag information in the register to 000.
Fig. 20 is a schematic diagram of a rotation state of a display device according to the present application, in fig. 20, when the display device is driven by the rotation device to rotate from a horizontal screen state to a second vertical screen state in a counterclockwise direction (a=1), bc=11 when the display screen is in a rotating state during the rotation, if an abnormality such as power failure occurs when the display device is not rotated to the second vertical screen state, the display device will be in a first possible tilt state as shown in the upper part of fig. 20, and the value of a register abc recorded in the second processor is 111. Therefore, when the rotation flag information of the display screen read by the second processor is 111, the second processor controls the rotation means to drive the display screen to continue to rotate in the counterclockwise direction corresponding to a=1 until the rotation screen is rotated to the first portrait state (101) as shown in the upper part of fig. 20, and then the second processor modifies the rotation flag information in the register to 101.
Also in fig. 20, when the display device is rotated from the second portrait state counterclockwise (a=1) to the landscape state by the driving of the rotating device, bc=11 when the display screen is in the rotating state during the rotation, if an abnormality such as power failure occurs when the display device is not rotated to the landscape state, the display device will be positioned in the second possible tilt state as shown in the lower side of fig. 20, and the value of the register abc recorded in the second processor is 111. Therefore, when the rotation flag information of the display screen read by the second processor is 111, the second processor controls the rotation means to drive the display screen to continue to rotate in the counterclockwise direction corresponding to a=1 until the rotation screen is rotated to the landscape screen state (100) as shown in the lower part of fig. 20, and then the second processor modifies the rotation flag information in the register to 100.
Optionally, in yet another example, the display device may be further rotated 360 degrees, and the rotation state of the display device may include: the first landscape state, the first portrait state, the second landscape state, the second portrait state, and the rotating state, and likewise, the rotating direction includes a clockwise direction or a counterclockwise direction.
