Meanwhile, in some split-type display devices, taking a television as an example, in order to meet the watching requirements of users on some vertical screen contents shot by a mobile phone, the display screen of the split-type television can be rotated. For example, fig. 8 is a schematic structural diagram of an embodiment of a display device provided in the present application, and the display device shown in fig. 8 may be the display device shown in any one of fig. 1 to 7, or may also be another display device not shown in fig. 1 to 7. Specifically, the display device provided by the present embodiment includes: host unit 1 and display screen 2, wherein, display screen 2 sets up outside host unit 1, with host unit 1 split type setting, namely, host unit 1 and display screen 2 set up independently of each other, realize the display device who has split type display screen. The host unit 1 comprises a first processor 11, the first processor 11 may be provided on a motherboard within the host unit 1, the display screen 2 comprises a second processor 21, and the second processor 21 may be provided on the motherboard within the display screen 2. The first processor 11 and the second processor 21 may be a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), a Micro Controller Unit (MCU), a System-on-a-Chip (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 power on 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 to the display screen 2, it should be noted that the host Unit 1 may also be referred to as a box, a box end, etc., and the display screen 2 may also be referred to as a screen end, etc. accordingly.

In particular, the display device in this embodiment further includes a rotating device 22 on the side of the display screen 2, where the rotating device may be a driving device such as a motor, a dc motor, or the like, and may be configured to rotate to provide an acting force for rotating the display screen 2, so as to drive the display screen 2 to rotate in the display plane, and rotate the display screen 2 to the display state such as the landscape screen state or the portrait screen state. For example, fig. 9 is a schematic structural diagram of a first rotation state of the display device provided in the present application, in which the rotation device is disposed on a non-display side of the display screen, and the rotation device can drive the display screen to rotate in a display plane of the display screen. It is to be understood that, in the drawing shown in fig. 8, the rotating means is drawn outside the display device only to illustrate the structure thereof, and the rotating means 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 provided in the present application, wherein the display screen shown in fig. 9 can be rotated from the landscape screen state to the portrait screen state shown in fig. 10 in the counterclockwise direction by being driven by the rotation device. It should be noted that, as two rotation states in fig. 9 and fig. 10 are only examples, the rotation device may also control the display screen to rotate to any other angle.

More specifically, as in the display device shown in fig. 8, the first processor 11 on the host unit 1 side may 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 display screen 2 side. In one specific implementation, the rotating device may be a 12V dc brushed electric motor (abbreviated as "motor"), and the second processor 21 may be configured to rotate via an H-bridge controlled electric motor model SGM 42600. The whole control process can be described as follows: first, the first processor 11 receives an instruction from a user, for example, the user sends an instruction indicating that the display screen 2 rotates 90 degrees clockwise to the first processor 11 of the host unit 1 through a remote controller or other means, and then the first processor 11 sends an indication signal, which can be used for indicating that the display screen 2 rotates 90 degrees clockwise, to the second processor 21 on the side of the display screen 2 through the connection line 3. Subsequently, upon receiving the indication signal, the second processor 21 may control the motor to select by outputting two signals IN1 and IN2 to the H-bridge. Illustratively, each of IN1 and IN2 may include four cases by combination of high and low levels, at least for motor-driven display screens to achieve the following three motion states: counterclockwise rotation, clockwise rotation, stall, and the like. For the H-bridge, according to the received rotation control signals IN1 and IN2, the two paths of voltages a and B output to the rotating device 24 are adjusted to control different states of the motor, so that the motor drives the whole display screen to rotate clockwise, rotate counterclockwise or stop rotating.

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 display screen to rotate 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 specifically be two hall magnet sets. The two hall magnet sets can feed back the rotation state to the second processor 21 through the output H1 and H2 signals after detecting the current rotation state of the rotating device (the state of the rotating device is the same as the state of the display screen rotation), and the second processor 21 can feed back the current rotation state of the rotating device to the host unit 1 through the connecting line 3, wherein the current 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, although the functions of controlling the rotation of the display screen, acquiring the rotation state, and the like are realized, the processing of some abnormal power failure and other abnormal situations that may occur is not perfect. For example, fig. 11 is a schematic diagram of a power-on state of the display device, in case 1A, after the display screen is in a horizontal screen state and is powered off, when the display screen is powered on again, a power-on display picture such as an icon 201 and the like may be displayed in the horizontal screen state, where the power-on display picture may be an icon of a display device manufacturer, an icon of a motherboard, or other static or dynamic images of power-on start, and the first part and the second part of the icon are used as upper and lower parts to display; in the case 1B, after the display screen is in the vertical screen state and is powered off, when the display screen is powered on again, the icons can be displayed in the vertical screen state, and the first part and the second part of the icons are used as the upper part and the lower part of the icons for displaying; however, if the display screen is in the case 1C, and an abnormal condition such as power failure occurs during rotation, it is necessary to determine the current rotation state of the display screen and then display a start page such as an icon, and the specific process is as shown in fig. 12.

Fig. 12 is a schematic diagram illustrating a start-up process of a display device in the prior art. The process of power-on starting after the display device is powered on as shown in fig. 8 is shown, and may be executed 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 last time the display device is turned off belongs to the abnormal power-off state and the display device is still rotating during the turning off, the power-on start-up process, such as the start-up of the first processor and the second processor, is started at S10 after the display device is powered on. After the first processor and the second processor are activated at S10, the second processor may execute S11 to activate the connected sensor, and after the sensor is activated and acquires the state of the display screen, the second processor determines the state of the display screen through S12. Subsequently, the first processor can acquire the current state of the display screen from the second processor through S13, for example, the current state is currently in a rotation state inclined as in case 1C shown in fig. 11, 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 as in

case

1A or 1B in fig. 11, and finally, after instructing the second processor to rotate the display screen, the first processor can send a power-on display picture to the second processor in S15 and normally display the picture in S16 after the entire display device is started up.

As shown in fig. 12, the prior art belongs to a general starting procedure of a display device, that is, after being powered on, the display device is started according to the sequence of a processor and a sensor, in this process, the starting process required for the split display device is more complicated, wherein the sensor is arranged behind the processor, the activation of the sensor can be controlled by the processor, the first processor needs to wait for the activation of the sensor before the rotation state detected by the sensor can be obtained by the second processor, and the first processor can send the startup display picture corresponding to the current state of the display device to the second processor to be displayed on the display screen, for example, if the display screen is in the landscape state, the first processor sends the power-on display screen to the second processor as shown in case 1A of fig. 11, and if the display screen is in the portrait state, the first processor sends the power-on display screen to the second processor as shown in case 1B of fig. 11. Therefore, the split type display apparatus shown in fig. 8 needs at least the following flow when dealing with the abnormality of the case 1C shown in fig. 11: the method comprises the steps of starting a processor, starting a sensor, detecting a rotation state of a display screen by the sensor, feeding back the rotation state of the display screen by the sensor, and indicating the rotation state of a second processor to adjust the rotation state of the display screen by a first processor, wherein after the steps are completely executed, the display screen is rotated to a horizontal screen state of a case 1A or a vertical screen state of a case 1B as shown in fig. 11, and then the display of a startup picture can be realized.

Therefore, for a long period of time after the first processor and the second processor are started at S10 before the first processor sends the power-on display screen to the second processor at S15, the display device will keep the abnormality of case 1C as shown in fig. 11, and the abnormality of this structure will also cause an abnormality in display, so that the display device displays an oblique icon or cannot display an icon. In 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 an abnormality in display, which lasts for several seconds or even ten seconds, and the power-on time of the display device is prolonged while displaying the abnormality, and for the user, the user cannot sense that the display device is powered on in the whole process of S10-S15, which greatly affects the user experience.

Therefore, how to adjust the rotation state of the display screen more quickly when restarting after the abnormal power failure of the split display device with the rotatable display screen, so as to prevent the abnormal display of the startup page such as the icon displayed on the display screen, is a technical problem that needs to be solved in the field.

The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

The application provides a control method of a display device and the display device, which can be applied to the display device shown in fig. 8, after abnormal power failure occurs in the rotation process of the display device, the rotation state of the display screen can be adjusted through a second processor arranged in the display screen in the restarting process, so that the rotation state of the display screen can be adjusted more quickly after starting up, the first processor can send a starting up display picture to the second processor more quickly, and abnormal display of a starting page such as an icon displayed by the display screen is prevented or the abnormal display time is reduced.

Fig. 13 is a flowchart illustrating an embodiment of a method for controlling a display device according to the present application, where the method shown in fig. 13 may be executed by the display device shown in fig. 8, and the following description is given with reference to fig. 8 and 13, where the method for controlling a display device according to the present application includes:

s101: the first processor and the second processor initiate a flow.

In the present embodiment, in the process of booting the display device shown in fig. 8, after the display device receives a boot instruction from a user, the display device starts to power on, and then the display device shown in fig. 8 starts a boot 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. The power required for the second processor 21 to start up may be the power supplied by 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, for example, the rotation state may be a current rotation state (a landscape state or a portrait state) of the display screen 2 after completing the rotation by the rotation device 22, or a rotation state (a rotation state) of the display screen 2 when the display screen 2 is not completed to rotate by the rotation device 22 and an abnormality such as a power failure occurs, and the rotation direction may be a rotation direction of the display screen when the display screen is not completed to rotate by the rotation device 22 and an abnormality such as a power failure occurs. The above rotation mark information may be represented 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.

Exemplarily, in a rotatable split type display device, fig. 14 is a schematic view of a rotation state of the display device provided by the present application, wherein the rotation state of the display screen at least includes: a landscape state, a portrait 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 the horizontal screen state, the display screen can be driven by the rotating device to rotate in the counterclockwise direction to the vertical screen state, but when the display screen is not rotated to the vertical screen state and is abnormal, the rotation state of the display screen is in the rotating state; similarly, when the display screen is in the vertical screen state, the display screen can be driven by the rotating device to rotate clockwise to the horizontal screen state, but when the display screen is not rotated to the horizontal screen state and is abnormal, the rotation state of the display screen is the rotating state.

The second processor may record the rotation direction and the rotation state of the display screen through two registers, respectively. For example, register a in the second processor may be configured to record a rotation direction of the display screen, (e.g., a clockwise direction a is 0 and a counterclockwise direction a is 1), and register b is configured to record a rotation state of the display screen, which may be represented by an output level of HIN1 or HIN2 of the hall sensor, where HIN2 is only detected when the display screen is rotated clockwise, and HIN2 is at a low level after the display screen is rotated clockwise to a landscape state, where b is 0; when the display screen rotates anticlockwise, only the HIN1 is detected, and the HIN1 is in a high level after the display screen rotates anticlockwise to a vertical screen state, wherein b is equal to 1, and b is equal to F when the display screen is in a rotating state.

Several possibilities for the rotation flag information stored in register a and register b are shown in table 1 below:

TABLE 1

Table 1 will be described with reference to fig. 14 to 16, for example, in the example shown in fig. 14, when the display device is rotated to the landscape state (b ═ 0) by a 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 counterclockwise direction (a 1), the values of the registers a and b recorded in the second processor are 00.

Fig. 15 is a schematic diagram of a rotation state of the display device provided in the present application, in fig. 15, when the display device is driven by the rotation device to rotate clockwise (a is 0) from the portrait screen state, b is F during the rotation, if an abnormality such as power failure occurs when the display device is not rotated to the landscape screen state, the display device will be in the inclined state as shown in fig. 15, and the values of the registers a and b recorded in the second processor are 0F; fig. 16 is a schematic diagram of a rotation state of the display device provided in the present application, in which, as shown in fig. 16, when the display device is driven by the rotation device to rotate counterclockwise (a equals to 1) from the portrait screen state, b equals to F during the rotation, and if an abnormality such as power failure occurs when the display device is not rotated to the landscape screen state, the display device will be in the inclined state shown in fig. 16, and the values of the registers a and b recorded in the second processor are 1F.

It is understood that, in this embodiment, the reading of the rotation mark information recorded in the at least one register by the second processor is performed during the power-on startup process. And under the condition of non-startup, when 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 modify the values in the registers a and b according to the rotation state acquired from the sensor in a mode shown in table 1, so as to realize real-time recording. Thus, when the display screen is rotating, the second processor 21 records the latest updated rotation mark information in real time even if the display device is powered off.

S103: the second processor controls the rotating device to rotate according to the rotating mark information so as to adjust the rotating state of the display screen.

Specifically, after the second processor reads the rotation mark 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 mark information, wherein the rotation of the display screen is driven by controlling the rotation of the rotating device, 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 of the display screen is in the landscape screen or the portrait 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 mark information of the display screen read by the second processor is 0F as shown in fig. 15, it indicates that the display screen is in a rotating state and is rotating clockwise but has not yet rotated to a landscape state, the second processor controls the rotating device to drive the display screen to continue rotating clockwise corresponding to a ═ 0 until the rotating screen is rotated to the landscape state as shown in fig. 15, and then the second processor modifies the rotation mark information in the register to 00.

When the rotation mark information of the display screen read by the second processor is 1F as shown in fig. 16, it indicates that the display screen is in a rotating state and is rotating counterclockwise but has not yet rotated to a portrait state, the second processor controls the rotating device to drive the display screen to continue rotating in the counterclockwise direction corresponding to a being 1 until the rotating screen is rotated to the portrait state as shown in fig. 16, and then the second processor modifies the rotation mark information in the register to 11.

The first processor may acquire the rotation state of the display screen from the second processor through S104 and perform subsequent processing after the second processor adjusts the rotation state of the display screen in S103. 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 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 acquiring the rotation state of the display screen in S104, and send the power-on display picture corresponding to the rotation mark information in S104 to the second processor on the side of the display screen through the connection line, and display the power-on display picture on the display screen. Specifically, the first processor may further send a display icon corresponding to the landscape screen or a display icon corresponding to the portrait screen to the second processor according to whether the current state of the display device is the landscape screen state or the portrait 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 abnormality of the display screen does not occur. In the process, the user can see that the display screen rotates to a horizontal screen state or a vertical screen state only after waiting for about 1 second, and the display screen displays the startup page after rotating, so that the technical problems that in the prior art, the display of startup pages such as icons displayed on the display screen is abnormal, the time required for recovering the abnormal display is long, and the waiting time of the user is long are solved.

Or, in other possible implementation manners, after the first processor is started, S104 may also be directly executed, but since the second processor may quickly correct the abnormality of the display screen through the parallel S102-S103 in about 1 second, and after that, the first processor may acquire the normal rotation state and overcome the display abnormality, thereby reducing the time for displaying the abnormality, and the first processor may recover to normal only in about 1 second, and also reduce the waiting time of the user to a certain extent, and improve the user experience of the display device.

Alternatively, in the method shown in fig. 13, after the first processor finishes booting through S101, S104 may be continuously performed to acquire rotation mark information recorded by the second processor, and after the rotation state is not the rotating state in the acquired rotation mark information, the step of S105 is performed.

It is understood that after S105, when the display device is started up, the whole S101-S105 may be understood as a starting process of the display device, and after that, the display device is in an operating state, according to a conventional work flow of the display device, for example, in S106, the first processor sends a display interface of the content to be displayed to the second processor, and the second processor displays a picture, and the like.

Finally, the display device provided in this embodiment can control the display screen to rotate by the second processor on one side of the display screen directly according to the rotation mark information recorded by the second processor in the process that the display device is restarted after the display device is abnormally powered off in the rotation process through the above steps, and it is no longer necessary to control the display screen to rotate after the processor is started, the sensor is started and the first processor and the second processor interact with each other as in the prior art shown in fig. 12. 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 can be adjusted to the horizontal screen state or the vertical screen state more quickly, and the time for abnormal display of the display device is reduced.

Alternatively, in the above examples of the rotation state of the display device shown in fig. 14 to 15, the display device may be rotated by 90 degrees, which is only an example for explaining the method shown in fig. 13, in other possible implementations, as another example, the display device may also be rotated by 180 degrees, and the rotation state of the display device may be described with reference to fig. 17 to 20, which is described below with reference to the attached drawings.

Fig. 17 is a schematic view of a rotation state of the display device provided in the present application, where the display state of the 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, obtained by clockwise rotation of the landscape state by 90 degrees), and a second portrait state (e.g., 3B in the figure, obtained by counterclockwise rotation of the landscape state by 90 degrees), and a rotating state during rotation; and the direction of rotation includes: clockwise or counterclockwise. When the display screen does not complete the rotation, at least the states include: clockwise rotation is not rotated to a first portrait screen state (as shown in fig. 2C), clockwise rotation is not rotated to a landscape screen state (as shown in fig. 3C), counterclockwise rotation is not rotated to a second portrait screen state (as shown in fig. 3C), and counterclockwise rotation is not rotated to a landscape screen state (as shown in fig. 2C).

The rotation direction and the rotation state of the display screen can be recorded through three registers in the second processor, respectively. For example, register a in the second processor may be used to record the rotation direction when the display screen rotates, (e.g., clockwise direction a is 0 and counterclockwise direction a is 1), register b and register c are used to record the rotation state of the display screen, e.g., register b and register c may be used to record the output level of HIN1 or HIN2 of the hall sensor, respectively, and then several types of rotation flag information stored in register a and register b may be as shown in table 2 below:

TABLE 2

	Rotate 90 degrees counterclockwise	0 degree	Rotate 90 degrees clockwise	Other states of rotation
					HIN1 (storing in register b)	0	0	1	1
HIN2 (storing in register c)	1	0	0	1

Table 2 is described below with reference to fig. 18 to 20, for example, fig. 18 is a schematic diagram of a rotation state of the display device provided in 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 the landscape state (bc 00) by 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 a first vertical screen state (bc 10) by clockwise (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 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 flag 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, the rotation state of the display screen may not be adjusted.

Fig. 19 is a schematic diagram of a rotation state of the display device provided in the present application, where in fig. 19, when the display device is driven by the rotation device to rotate from the landscape screen state to the first portrait screen state clockwise (a is 0), bc is 11 when the display screen is in the rotation state during the rotation process, and if an abnormality such as power failure occurs when the display screen is not rotated to the first portrait screen state at this time, the display device will be positioned in the first possible tilt state shown in the upper side of fig. 19, and the value of the 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 device to drive the display screen to continue rotating in the clockwise direction corresponding to a being 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 driven by the rotation device to rotate clockwise (a is 0) from the second portrait orientation to the landscape orientation, bc is 11 when the display screen is in the rotating orientation during the rotation, and if an abnormality such as power-off occurs when the display screen is not rotated to the landscape orientation, the display device will be positioned in the second possible tilted orientation as shown in the lower part of fig. 19, and the value of the 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 rotating device to drive the display screen to continue rotating in the clockwise direction corresponding to a being 0 until the rotating screen is rotated to the landscape state (000) as shown in the lower part 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 the display device provided in the present application, where in fig. 20, when the display device is driven by the rotation device to rotate from the landscape screen state to the second portrait screen state in the counterclockwise direction (a is 1), bc is 11 when the display screen is in the rotation state during the rotation process, and if an abnormality such as power failure occurs when the display screen is not rotated to the second portrait screen state at this time, the display device will be in the first possible tilt state shown in the upper side of fig. 20, and the value of the register abc recorded in the second processor is 111. Therefore, when the rotation mark information of the display screen read by the second processor is 111, the second processor controls the rotating device to drive the display screen to continue rotating in the counterclockwise direction corresponding to the direction a being 1 until the rotating 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 mark information in the register to be 101.

Also in fig. 20, when the display device is driven by the rotation device to rotate counterclockwise (a is 1) from the second portrait orientation to the landscape orientation, bc is 11 while the display screen is in the rotating orientation during the rotation, and if an abnormality such as power-off occurs while the display screen is not in the landscape orientation, the display device will be positioned in the second possible tilted orientation as shown in the lower portion of fig. 20, and the value of the register abc recorded in the second processor is 111. Therefore, when the rotation mark information of the display screen read by the second processor is 111, the second processor controls the rotating device to drive the display screen to continue rotating in the counterclockwise direction corresponding to the direction a being 1 until the rotating screen is rotated to the landscape state (100) as shown in the lower part of fig. 20, and then the second processor modifies the rotation mark information in the register to 100.

Optionally, in a further example, the display device may further rotate 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. It will be appreciated that in this example, the second processor may represent the four states by more registers, for example, register a records the direction of rotation: the clockwise direction a is 0, and the anticlockwise direction a is 1; five rotation states are recorded by registers b, c and d: a first landscape state 000, a first portrait state 001, a second landscape state 010, a second portrait state 011, and a rotating state 111. The second processor may also control the display screen to rotate according to the rotation flag information recorded in the register after the second processor is powered on, and the specific implementation manner may refer to the embodiment shown in fig. 13 and is not described again.
