As can be seen from the foregoing technical solutions, in a display device provided in an embodiment of the present application, in addition to a first processor configured to receive display information sent by an electronic device and control output data of a display according to a display signal, a second processor configured to send a control instruction to the electronic device is also configured in the display device, so that the electronic device executes a corresponding operation according to the control instruction. Therefore, the display device in this embodiment can control the output data of the display according to the display information sent by the electronic device, and can also send a control instruction to the electronic device to control the electronic device to execute a corresponding operation, thereby implementing control over the electronic device.

In one implementation, the first processor 2 and the second processor 3 are independently located, a first channel 4 is established between the second processor 3 and the electronic device, and a second channel 5 is established between the second processor 3 and the first processor 2, as shown in fig. 2.

Therefore, in the implementation scheme, an independent Monitor Aid Controller is used inside the display device, and the display device is provided with a USB interface and other interface capabilities. The Monitor Aid Controller communicates with the Host PC using a USB port, and the Monitor Aid Controller communicates with a Monitor Main CPU (e.g., scaler) using any available port, such as I2C, SPI, GPIO, USB, etc. Furthermore, the USB connection between the Monitor Aid Controller and the Host PC can be ase:Sub>A common USB cable, such as USB-A, USB-B, etc., or ase:Sub>A USB channel included in other communication cables, such as ase:Sub>A USB channel in USB-C, in physical form. In addition, the USB connection between the Monitor Aid Controller and the Host PC can be a direct connection or an indirect connection through other components (such as a USB HUB).

The first channel 4 is established on the basis of the second interface 8, the expansion unit 7 and the third interface 9. The extension interface 10 is of the same interface type as the second interface 8 and the third interface 9

Taking the extension part 7 as a USB Hub and the second interface 8 as a USB interface as an example, as shown in fig. 6, the Host PC is connected to the USB Hub through a USB interface, the USB Hub is connected to the Monitor Aid Controller through a USB interface (i.e., a third interface 9), and a first channel 4 is established based on the USB Hub, and is used for sending a display signal transmitted by the Host PC to the Monitor Aid Controller, so that the Monitor Aid Controller transmits the display signal to the Monitor Main CPU, and also for transmitting a control instruction sent by the Monitor Aid Controller to the Host PC, so that the Host PC executes a corresponding operation according to the control instruction; the Monitor Aid Controller is connected with the Monitor Main CPU through an I2C interface, an SPI interface, a GPIO interface or a USB interface, and a second channel 5 is established on the basis of the interface and used for sending a display signal transmitted by the Monitor Aid Controller to the Monitor Main CPU so that the Monitor Main CPU controls the output data of the display according to the display signal.

As can be seen, in this implementation, the Host PC and the display are connected viase:Sub>A ase:Sub>A common USB port (e.g., USB-A, USB-B, etc.). The USB Hub is optional and may not be needed if the display does not need to provide an external USB port. Moreover, any available port can be used for communication between Monitor Aid Controller and Monitor Main CPU, such as I2C, SPI, GPIO, USB, etc.

In one implementation, the second processor 3 is provided in the first processor 2, and a first channel 11 is established between the first processor 2 and the electronic device, as shown in fig. 7.

The first channel 11 is configured to transmit a display signal sent by the electronic device to the first processor 2, so that the first processor 2 controls output data of the display 1 according to the display signal; moreover, the first channel 11 is further configured to transmit a control instruction obtained by the first processor 2 from the second processor 3 to the electronic device, so that the electronic device performs a corresponding operation according to the control instruction.

Based on the above implementation manner, in a specific implementation scheme, the first processor 2 is connected with the electronic device through the fourth interface 12, and the first channel 11 is established based on the fourth interface 12, as shown in fig. 8.

Taking the fourth interface 12 as an USB interface as an example, as shown in fig. 9, the Host PC is connected to the first processor 2 through the USB interface, and a first channel 11 is established based on the USB interface and is used for transmitting the display signal sent by the Host PC to the Monitor Main CPU, so that the Monitor Main CPU controls the output data of the display according to the display signal, and is also used for transmitting the control instruction obtained by the Monitor Main CPU from the Monitor Aid Controller to the Host PC, so that the Host PC executes a corresponding operation according to the control instruction.

Therefore, in the implementation scheme, the Monitor Aid Controller is implemented in the Monitor Main CPU, and can be recognized as a USB device in the Host PC, so that the Monitor Aid Controller can communicate with the Host PC. Further, the USB connection between the Monitor Main CPU and the Host PC may be ase:Sub>A common USB cable, such as USB-A, USB-B, etc., or ase:Sub>A USB channel included in other communication cables, such as ase:Sub>A USB channel in USB-C, in physical form. In addition, the USB connection between the Monitor Main CPU and the Host PC can be a direct connection or an indirect connection through other chips (such as a USB HUB).

Or, in another specific implementation, the display device in this embodiment further includes the following structure, as shown in fig. 10:

the expansion component 13 is connected with the electronic equipment through a fifth interface 14, and the expansion component 13 is connected with the first processor 2 through a sixth interface 15; the expansion component 13 further comprises an expansion interface 16, wherein the expansion interface 16 is used for connecting other components;

wherein the first channel 11 is established based on the fifth interface 14, the expansion component 13 and the sixth interface 15, and the expansion interface 16 is of the same interface type as the fifth interface 14 and the sixth interface 15.

Taking the expansion part 13 as a USB Hub and the fifth interface 14 as a USB interface as an example, as shown in fig. 11, the Host PC is connected to the USB Hub through a USB interface, the USB Hub is connected to the Monitor Main CPU through a USB interface (i.e., the sixth interface 15), and a first channel 11 is established based on the USB Hub for transmitting a display signal sent by the Host PC to a Monitor Main CPU such as a Scaler, so that the Monitor Main CPU controls output data of the display according to the display signal, and also for transmitting a control instruction obtained by the Monitor Main CPU from a Monitor Aid Controller to the Host PC, so that the Host PC performs a corresponding operation according to the control instruction.

As can be seen, in this implementation, the Host PC and the display are connected viase:Sub>A ase:Sub>A common USB port (e.g., USB-A, USB-B, etc.). The USB Hub is also optional and may not be needed if the display does not need to provide an external USB port. Moreover, the Monitor Aid Controller is realized in the Monitor Main CPU, and can be recognized as a USB device in the Host PC, so that the Monitor Aid Controller can be communicated with the Host PC.

In an implementation manner, the first processor 2 and the second processor 3 are independently disposed, and the display device in this embodiment may further include the following structure, as shown in fig. 12:

a control part 17, the control part 17 being connected between the electronic device and the first processor 2; the control section 17 is for separating display data and control data in the display signal;

an expansion part 18, the expansion part 18 being connected between the second processor 3 and the control part 17; the expansion part 18 also comprises an expansion interface 19, and the expansion interface 19 is used for connecting other parts;

a first channel 20 is established between the electronic device and the first processor 2 through the control component 17, and the first channel 20 is used for transmitting display data in the display signal to the first processor 2;

a second channel 21 is established between the electronic device and the second processor 3 through the control part 17 and the expansion part 18, and the second channel 21 is used for transmitting the control instruction sent by the second processor 3 to the electronic device.

Furthermore, a third channel 22 is established between the second processor 3 and the first processor 2, and the control data in the display signal is transmitted to the first processor 2 through the second channel 21 and the third channel 22;

wherein, the control part 17 is connected with the electronic device through a seventh interface 23; the control unit 17 is connected to the expansion unit 18 via an eighth interface 24, and the expansion unit 18 is connected to the second processor 3 via a ninth interface 25; the seventh interface 23 is of a different interface type from the eighth interface 24, the eighth interface 24 is of the same interface type as the ninth interface 25, and the expansion interface 19 is of the same interface type as the eighth interface 24.

Taking the expansion part 18 as a USB Hub, the control part 17 as a USB-C Controller and the seventh interface 23 as a USB-C interface as an example, as shown in fig. 13, the Host PC and the USB-C Controller are connected through a USB-C, the USB-C Controller and the Monitor Main CPU are connected through a DP (DisplayPort) interface, based on which a first channel 20 is established between the Host PC and the Monitor Main CPU, after the USB-C Controller separates the display data and the control data in the display signal, the USB-C Controller transmits the display data in the display signal to the Monitor Main CPU through the first channel 20, the USB-C Controller and the USB Hub are connected through a USB interface (i.e., an eighth interface 24), the USB Hub and the Monitor Aid Controller are connected through a USB interface (i.e., a ninth interface 25), based on which a second channel is established between the Host PC and the Monitor Aid Controller, so that the Monitor Controller executes the control instruction through the second channel 21, thereby controlling the Monitor Aid to execute the operation according to the Host PC; and the Monitor Aid Controller is connected with the Monitor Main CPU through an I2C interface, an SPI interface, a GPIO interface or a USB interface, and on the basis, a third channel 22 is established between the Monitor Aid Controller and the Monitor Main CPU, so that after the USB-C Controller sends the separated control data to the Monitor Aid Controller through a second channel 21 established by a USB Hub, the Monitor Main CPU can receive the control data sent by the Monitor Aid Controller through the third channel 22, so that the Monitor Main CPU processes the display data according to the control data, and further controls the output data on the display.

It can be seen that in this implementation, the USB-C Controller and the USB Hub are optional, because the USB-C bus physically contains a DP signal (USB-C alternate mode) and a USB signal, and can be directly separated, and meanwhile, if the display does not need to provide an external USB port, the USB Hub is also not needed. Furthermore, the Monitor Aid Controller is any MCU with USB port, which must implement a USB device to identify the device in the Host PC so that it can communicate with the Host PC. In this case, the Monitor Main CPU and the Monitor AID Controller can communicate with each other through any channel, such as I2C, SPI, GPIO, USB, etc. The Monitor Aid Controller is identified in the Host PC as a USB device. In addition, the Host PC sends the display signal to the Monitor Aid Controller, and the Monitor Aid Controller sends the display signal to the Monitor Main CPU. Otherwise, the Monitor Aid Controller sends the control instruction to the Host PC through the USB.

In one implementation, the second processor 3 is disposed in the first processor 2, and the display device in the present embodiment may further include the following structure, as shown in fig. 14.

A control section 26, the control section 26 being connected between the electronic device and the first processor 2; the control section 26 is for separating display data and control data in the display signal;

an expansion section 27 connected between the first processor 2 and the control section 26; the expansion unit 27 further comprises an expansion interface 28, and the expansion interface 28 is used for connecting other components;

a first channel 29 is established between the electronic device and the first processor 2 through the control component 26, and the first channel 29 is used for transmitting display data in the display signal to the first processor 2;

a second channel 30 is established between the electronic device and the first processor 2 through the control component 26 and the expansion component 27, the second channel 30 is used for transmitting a control instruction acquired by the first processor 2 from the second processor 3 to the electronic device, and is also used for transmitting control data in a display signal acquired by the expansion component 27 from the control component 26 to the first processor 2, so that the first processor 2 processes the display data according to the control data to control output data of the display 1;

wherein, the control part 26 is connected with the electronic device through a tenth interface 31; the control unit 26 is connected to the expansion unit 27 via an eleventh interface 32, and the expansion unit 27 is connected to the first processor 2 via a twelfth interface 33; the tenth interface 31 is different from the eleventh interface 32 in interface type, and the eleventh interface 32 is the same as the twelfth interface 33 in interface type.

Taking the expansion part 27 as a USB Hub, the control part 26 as a USB-C Controller and the tenth interface 31 as a USB-C interface as an example, as shown in fig. 15, a first channel 29 is established between the Host PC and the USB-C Controller through a USB-C connection, the USB-C Controller and the Monitor Main CPU are connected through a DP interface, based on which, after the USB-C Controller separates the display data and the control data in the display signal, the USB-C Controller transmits the display data in the display signal to the Monitor Main CPU through the first channel 29, the USB-C Controller and the USB Hub are connected through a USB interface (i.e., an eleventh interface 32), the USB Hub and the Monitor Main CPU are connected through a USB interface (i.e., a twelfth interface 33), based on which, a second channel 30 is established between the Host PC and the Monitor Main CPU, the Monitor Main CPU can transmit the control data obtained from the Controller to the Monitor Main CPU through the Monitor Main control channel 30, and the Monitor Main CPU can process the display data and output the control data through the Monitor Main control channel 30, thereby controlling the Monitor Main CPU to execute the Monitor Main CPU to process the display data according to the Monitor Main control data obtained by the Monitor Main CPU, and send the Monitor Main control data.

It can be seen that in this implementation, the USB-C Controller and the USB Hub are optional, because the USB-C bus physically contains a DP signal (USB-C alternate mode) and a USB signal, and can be directly separated, and meanwhile, if the display does not need to provide an external USB port, the USB Hub is also not needed. Also, in this case, the Monitor Aid Controller is implemented inside the Monitor Main CPU, which can be recognized as a USB device in the Host PC, thereby enabling communication with the Host PC.

In one implementation, the display device may further include the following structure, as shown in fig. 16:

an input device 34; the input device 34 is used to generate input signals, which are used to generate control commands.

In a specific implementation, the control instruction may be an instruction instructing the electronic device to execute a target instruction, and the target instruction is used for providing a corresponding functional service. For example, a physical button is configured on the display device, or a touch screen is configured on the display 1 to output a control interface, a function control is output in the control interface, based on which, a user can perform selection operation, such as pressing or clicking, on the physical button or the function control, so that the input device on the display device can generate an input signal corresponding to the user pressing the physical button or clicking the function control, and further generate a corresponding control instruction based on the input signal, after the control instruction is transmitted to the electronic device, the electronic device can execute a target instruction according to the control instruction, so as to provide a corresponding functional service, such as starting a certain application program, or placing a window of the certain application program at a front end for operation.

In another specific implementation, the input signal is a signal for adjusting a display parameter of the display, so that the control instruction is an instruction for instructing the electronic device to synchronously display the parameter. For example, the input signal is a signal for adjusting the display contrast of the display 1, based on which, after the control instruction is transmitted to the electronic device, the electronic device can synchronize the parameters of the display contrast among the configuration parameters for the display 1 in the electronic device in accordance with the control instruction.

Specifically, the display 1 displays the display parameters through the first interface, and when the first interface and the output data corresponding to the display signal are displayed on the display at the same time, the first interface affects the display of the output data corresponding to the display signal on the display. For example, the Display 1 displays various Display parameters such as brightness, contrast, etc. through an interface of an On Screen Display (OSD). Based on this, when the user uses the display to output the output data corresponding to the display signal of the electronic device, the OSD interface is invoked, the OSD interface is displayed on the top layer of the display, so that the original output data of the display is blocked, and the user operates the adjustment control corresponding to the display parameter of the display 1 through the touch screen (the input device 34), so as to generate the input signal for adjusting the display parameter of the display 1, such as contrast or brightness, and further generate the control instruction on the display device, after the control instruction is transmitted to the electronic device, the electronic device can synchronize the parameter for displaying the contrast in the configuration parameters of the display 1 in the electronic device according to the control instruction, for example, synchronize the corresponding display parameter in soft OSD software in the electronic device.

For example, a button may be placed on the display, and based on the foregoing implementation, the host may be activated to initiate a function (e.g., to invoke a piece of software or to run a function of a piece of software or system). For another example, after the user sets the display parameters (e.g., brightness, contrast) through the OSD, based on the foregoing implementation, the setting can be synchronized to the soft OSD software on the host. For another example, when a fault or a status change (for example, a device is plugged in) occurs inside the display itself, based on the foregoing implementation scheme, the host may be notified to take a corresponding measure.

In summary, based on the foregoing implementation scheme, in this embodiment, a dedicated auxiliary display controller is implemented inside the display, and is dedicated to communicate with the host, where the auxiliary display controller may be an independent hardware control module, or an equipment module implemented inside a main processor of the display. After the scheme in the embodiment is used, the display and the host can carry out two-way communication, and the command sent by the host can be received and also can be sent to the host.

In addition, a second processing method provided in the second embodiment of the present application may be applied to a second processor in the display device shown in fig. 1, where the display device further includes a first processor and a display, and the first processor is configured to receive a display signal sent by the electronic device and control output data of the display according to the display signal. And the following method may be included on the second processor:

and sending a control instruction to the electronic equipment so that the electronic equipment executes corresponding operation according to the control instruction.

As can be seen from the foregoing technical solutions, in a processing method provided in the second embodiment of the present application, in addition to configuring a first processor capable of receiving display information sent by an electronic device and controlling output data of a display according to a display signal, a second processor capable of sending a control instruction to the electronic device is also configured in a display device, so that the electronic device executes a corresponding operation according to the control instruction. Therefore, the display device in this embodiment can control the output data of the display according to the display information sent by the electronic device, and can also send a control instruction to the electronic device to control the electronic device to execute a corresponding operation, thereby implementing control over the electronic device.
