Optionally, in this embodiment of the application, since the host 1 respectively supplies power to the backlight module 22 and the display panel 24 of the display screen 2 through two electrical signals, in order to unify timing sequences of the two, after the SOC212 determines that the display screen 2 is connected to the host 1 through the connection line 3, the host 1 starts to supply power to the display screen 3 through the connection line 3, and determines that the HDMI signal is stable, the STB signal may be first sent to the display control circuit 215 in the display screen 2 to indicate that power can be supplied to the display panel, and then the display control circuit 215 may be turned on after receiving the STB signal, so that the 12V power transmitted by the host 1 may supply power to the display panel 23 through the display control circuit 215. Subsequently, the SOC212 receives the HDMI signal again, converts the HDMI signal into a VB1 signal, and transmits the signal to the display panel 23 for display. Finally, after a certain delay, the SOC212 controls the backlight control circuit 213 to supply power to the backlight module 22. Alternatively, in the circuit diagram shown in fig. 12, the display control circuit 215 may be implemented by a switching transistor, such as a MOS transistor, which is turned on after receiving the STB signal.

3. The control signals between the host 1 and the display screen 2 interact.

The control signal between the host 1 and the display screen 2 may be implemented by an I2C (also may be referred to as IIC) channel, wherein the SOC111 in the host 1 may be connected to the SOC212 in the display screen 2 through a fourth communication interface in the first connection line interface 112, a transmission line in the connection line 3 for transmitting the I2C signal, and a fourth communication interface in the second connection line interface 211 in sequence, and send the control signal to the SOC 212. Then, for the SOC212 of the display screen 2, the control signal sent by the SOC111 of the host 1 through the connection line 3 can be received through a fourth communication interface (i.e., I2C communication interface in fig. 12) on the second connection line interface 211, and the fourth communication interface is connected to the transmission line for transmitting the I2C signal in the connection line 3, where the control signal can be used for the SOC212 to perform relevant control, such as control of the rotating structure 24 by the SOC 212. Optionally, the backlight control circuit 213 may also receive a backlight control signal sent by the host 1 through the I2C communication interface, and adjust the brightness of the backlight module according to the backlight control signal.

4. The host 1 controls the rotation structure 24 of the display screen 2 to rotate through the connection line 3.

As shown in fig. 9 and 10, since the rotation structure 24 is disposed on the side of the display screen 2, the host 1 also needs to control the rotation structure through the connection line 3 connected to the display screen 2 only. Specifically, in the example shown in fig. 12, since the rotary structure is disposed on the outer surface of the non-display side of the display screen and the main board is disposed inside the display screen, a control interface 217 (i.e., a USB-C interface in fig. 12) may be disposed on the main board 212, so that the SOC212 located inside the display screen is connected to the rotary structure 24 through the USB-C interface and controls the rotary structure 24 through the control interface.

Optionally, the rotating structure 24 includes a motor and two hall magnet sets, the rotation control circuit arranged on the main board 21 of the display device 2 is an H-bridge, the model of the H-bridge may be SGM42600, a double-bridge parallel design is adopted, and current is limited by 3A; the motor can use a 12V direct current brush motor. The SOC111 in the host 1 may send a rotation command to the SOC212 of the display screen 2 through the transmission line for transmitting the I2C signal in the connection line 3, and when the SOC212 receives the command through the I2C communication interface on the second connection line interface 211 and determines that it is necessary to control the rotation of the rotary structure 24, the SOC212 sends a rotation control signal to the rotation control circuit 216 to control the rotation of the motor in the rotary structure 24. IN this embodiment, the rotation control signal can be represented by two signals IN1 and IN2 output by the H-bridge, and each of IN1 and IN2 can include four cases, for example, by the combination of high and low levels, which can be used at least for the motor-driven display screen to realize 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 structure 24 are adjusted to control different states of the motor, so that the motor drives the whole display screen to rotate clockwise, counterclockwise or stop rotating.

Meanwhile, the rotating structure 24 further includes two hall magnet sets, which are used for detecting the current rotating state of the rotating structure 24 and feeding the rotating state information back to the SOC212 through the USB-C interface via H1 and H2 signals, and the SOC212 may feed the current state of the rotating structure (the state of the rotating structure is the same as the rotating state of the display screen) back to the host 1 via the I2C channel, where the current state of the rotating structure at least includes: 0 degree, 90 degrees, -90 degrees, etc., so that the SOC212 can determine whether selection is needed according to the state of the display device, for example, after the display device is powered on, the SOC212 determines that the current state of the rotating structure is 90 degrees according to the H1 and H2 signals, that is, the display screen is 90 degrees, and it is needed to rotate the display screen back to 0 degree, and then the SOC212 can control the motor of the rotating structure 24 to rotate through the signals IN1 and IN2, and rotate the display screen to 0 degree.

Alternatively, the H-bridge as shown in fig. 12 may also output an nFAULT signal to SOC212, where the nFAULT signal may be at a high level during normal operation, and when the motor is over-current, over-heat, etc., the abnormality of rotating structure 24 of SOC212 is notified by setting the nFAULT signal to a low level.

5. And (3) on-off state interaction between the host 1 and the display screen 2.

The connection line 3 between the host 1 and the display screen 2 further includes a UART connection, and the SOC111 of the host 1 may sequentially connect to the SOC212 in the display screen 2 through the fifth communication interface in the first connection interface 112, the transmission line for transmitting the UART signal in the connection line 3, and the fifth communication interface in the second connection interface 211, and transmit a UART signal such as an on/off signal to the SOC 212. For the SOC212 of the display screen 2, the on/off signal transmitted by the host 1 may be received through the fifth communication interface (i.e., the UART communication interface in fig. 12) of the second connection line interface 211, and the on/off state may also be transmitted to the SOC111 of the host 1 through the fifth communication interface, the on/off signal including: the power-on, power-off and standby signals, the power-on and power-off state comprises: a power-on state, a power-off state, and a standby state. For example, in the standby process, after the SOC111 of the host 1 is turned off and it is determined that a user presses a standby key is received, a standby signal is sent to the SOC212 of the display screen 2 through the URAT communication interface to instruct the display screen 2 to enter a standby flow and turn off power supply to the display screen to enter a standby state, and after that, the SOC of the host 1 may be notified through the URAT communication interface that the SOC currently enters the standby state.

6. Acquisition and processing of the rotation state of the display screen 2 when rotated.

In addition to the display screen 2 receiving the rotation state of the motor fed back by the rotating structure through the USB-C interface, an accelerometer and/or a gyroscope 219 may be disposed inside the display screen 2 for detecting information such as the speed of the display device when the display device is driven by the motor of the rotating structure 24 to rotate, and adjusting the display device when the speed is too high. For example, as shown IN fig. 12, the accelerometer and/or gyroscope 219 is connected to the screen SOC212 via I2C INT, when the accelerometer and/or gyroscope 219 detects an abnormal rotation condition such as too fast acceleration, an interrupt signal (INT) may be sent to the SOC212, so that the SOC212 controls the rotating structure 24 to stop rotating via signals IN1 and IN 2.

Alternatively, during the power-on process of the display device, the SOC212 on the side of the display screen 2 may determine the current initial state (e.g., 0 degrees, 90 degrees, or-90 degrees) of the display screen 2 through the accelerometer and/or gyroscope 219, and may transmit the initial state to the SOC111 on the side of the host 1 through the URAT. In addition, the accelerometer and/or gyroscope 219 may also be connected to the motherboard 1 through an I2C communication interface of the second connection line interface, so that the SOC111 of the motherboard 1 may read the state of the display screen detected by the accelerometer and/or gyroscope 219 through I2C. In order to obtain the status of the display screen in real time on the host 1 side, an I2C interface may be further provided in the second connection line interface for the accelerometer and/or the gyroscope 219, instead of being multiplexed with other I2C interfaces that need to be used.

Optionally, the SOC212 on the side of the display screen 2 may also determine the real-time position to which the display screen is currently rotated through H1 and H2 signals fed back from the hall magnet group in combination with the accelerometer and/or gyroscope 219.

7. The display screen 2 is connected to other external devices such as a camera.

In addition, in addition to the above interfaces, an expansion interface (i.e., "S7E interface" in fig. 12) may be further disposed on the main board 21 in the display screen 2 provided in the embodiment of the present application, and may be used to connect more peripherals supporting the USB2.0 protocol. For example, in fig. 12, the main board 21 may be connected to the camera 25 through an expansion interface, and the second connection line interface 211 is also provided with a USB2.0 communication interface, so that the host 1 may sequentially perform data transmission with the peripheral camera 25 through the USB2.0 communication interface connection line 3 of the first connection line interface 112, the USB2.0 communication interface of the second connection line interface 211, and the expansion interface.

8. After the host 1 is connected with the display screen 2, the safety detection of slow power-on is carried out.

Wherein, still be provided with resistance 218 on the mainboard 21 of display screen 2 one side, wherein, the sixth communication interface (promptly, HILINK HPD communication interface in fig. 12) of second connecting wire interface is connected to the first end of resistance 218, the first end of sixth communication interface can be connected with the host computer after second connecting wire interface inserts the connecting wire, the second end ground connection of resistance 218, can be used to detect whether the second connecting wire interface that is located display screen one side passes through the first connecting wire interface connection of connecting wire and host computer one side, namely, can be used to detect whether display screen is connected with the host computer.

Specifically, in the display device provided in the embodiment of the present application, the host 1 supplies power to the backlight module of the display screen 2 through the connection line 3, and the 150V voltage for supplying power transmitted on the connection line 3 is high, in order to prevent a user from causing a safety hazard to the display device itself and the user when the connection line between the display screens 2 of the host 1 is not connected due to lack of experience in use or improper operation, the host 1 transmits a high voltage of 150V directly to the display screen 2 through the connection line 3, therefore, the resistor 218 for detection is provided on the motherboard 21 on the side of the display screen 2, when the display screen 2 is not connected to the host 1 through the connection line 3, the resistor 218 pulls the communication interface hik HPD connected at the first end high level, when the display screen 2 is connected to the host 1 through the connection line 3, that is, the first connection interface and the second connection interface are connected through the connection line 3, the resistor 218 pulls the communication interface hik HPD low level, and at the same time, the communication interface 2v6a starts to supply power to the display device through the power supply control circuit, especially, the communication interface 5 sends a high voltage to the host interface 12 after the communication interface SOC1 is received through the connection line. For the SOC of the host 1, only after receiving the HILINK HPD of the low level and the HDMI HPD of the high level at the same time, it can be determined that the host 1 and the display device 2 have completed the connection through the connection line 3, and then the 150V voltage is transmitted to the display screen 2 through the connection line 3, thereby ensuring that the host 1 transmits the 150V high voltage to the display screen 2 through the connection line 3 under the condition that the connection line 3 between the display screens 2 of the host 1 is connected, and reducing the potential safety hazard brought by the display device itself and the user.

9. In order to realize the functions, the first connecting line interface and the second connecting line interface are designed.

Further, in order to implement the above functions, the display device needs to provide a communication interface in the first connection interface 112 on the host 1 side and a corresponding communication interface in the second connection interface 211 on the display screen 2 side, so that the transmission lines of the connection lines 3 for transmitting corresponding signals are connected to the corresponding communication interfaces on both sides, respectively, to implement the related functions. For example, for the HDMI interface provided in the second connection line interface 211, the HDMI interface is also provided in the first connection line interface 112, and after the two ends of the transmission line for transmitting HDMI signals in the connection line 3 are connected to the two HDMI interfaces, the transmission of HDMI signals can be realized between the first connection line interface 112 and the second connection line interface 211, and thus, the transmission of HDMI signals between the host 1 and the display screen 2 is also realized.
