It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an all-in-one machine according to the present invention, where the all-in-one machine may include:
the all-in-one machine structure comprises an all-in-one machine structure main body;

and a backlight circuit 50 connected to the trigger circuit 30.
Specifically, the all-in-one machine described in the present application may be a computer or a server, and of course, in practical applications, other electronic devices having a CPU may also apply the solution of the present application according to practical needs. The most common application of the present application is in computers, particularly PCs, and the present application will be described with reference to PCs as an example.
The main body of the all-in-one machine structure refers to other devices in the all-in-one machine besides the switching controller 10, the target switch 20, the trigger circuit 30, the display 40 and the backlight circuit 50, and the specific content depends on the specific structure of the all-in-one machine in practical application. The drawings of the present application do not show the structural body of the unitary machine.
In practical applications, the switching controller 10, the target switch 20 and the trigger circuit 30 may be disposed in a motherboard of the CPU. The form of the CPU can be selected according to actual needs, for example, the FT2000_4 core processor based on the ARM platform can support a dual-channel DDR4 memory, and two sets of PCIE X16 and two sets of PCIE X1 resources are integrated, so that the operation performance of the CPU is greatly improved. The scheme of the application is applied to the PC mainboard based on the FT2000_4 core CPU, so that the PC can be used as a receiving device of an external HDMI signal while realizing the original function, namely, as a high-definition display, the core competitiveness of the product is further improved, and the use requirements under different environments are met.
As described above, the conventional PC is usually provided with an HDMI output interface, but an input interface for receiving an external HDMI signal is not provided, and a specific switching manner is not provided, so that the conventional PC cannot be used as a receiving device for an external HDMI signal. The specific device type of the switching controller 10 may also be set according to actual needs, as long as the functions described in the present application can be implemented, for example, HDMI IN RTD2522A may be selected as the switching controller 10 of the present application.
The target switch 20 is connected to the switching controller 10 so that the switching controller 10 can know the current state of the target switch 20. The operator operates the target switch 20 to control whether the target switch 20 is in the first state or the second state, thereby affecting the output of the switching controller 10.
Specifically, when the target switch 20 is in the first state, the switching controller 10 performs protocol conversion on the display data in the HDMI signal received from the first input interface and transmitted by the local display card, and outputs the display data through the display interface. Accordingly, when the target switch 20 is in the second state, the switching controller 10 performs protocol conversion on the display data in the HDMI signal received from the second input interface and transmitted by the external device, and outputs the display data through the display interface. In the drawings of the present application, the first input interface and the second input interface of the switching controller 10 are denoted as HDMI _1 and HDMI _2, respectively.
The specific form of the protocol conversion may be preset and may be adjusted according to actual needs, for example, in an embodiment of the present invention, the display interface is a widely used LVDS interface, that is, the display data in the HDMI signal is converted into data meeting the LVDS standard, so that the display 40 can display the data. In addition, in other cases, the display interface may be in the form of EDP, DP, or the like.
It should be noted that, no matter the display 40 displays the display data in the HDMI signal sent by the local display card or displays the display data in the HDMI signal sent by the external device, the backlight function needs to be turned on. In the solution of the present application, no matter the switching controller 10 receives the HDMI signal sent by the local display card or the HDMI signal sent by the external device, the switching controller 10 will start the backlight circuit 50 through the trigger circuit 30.

It should be noted that, in practical application, the specific configuration of the trigger circuit 30 may be determined according to actual needs, as long as the requirements that "when the switching controller 10 receives an HDMI signal sent by the local display card or an HDMI signal sent by the external device, the backlight is turned on, and when the switching controller 10 does not receive an HDMI signal sent by the local display card and also does not receive an HDMI signal sent by the external device, the backlight is turned off" are met.

In fig. 2, an interface connecting the first resistor R1 with the backlight circuit 50 is denoted as a BKL interface, and a backlight enable signal of the local display card is denoted as a BKL _ EN.
When the switch controller 10 receives the HDMI signal transmitted by the external device, the first control signal is 1, and the target switch 20 outputs 1 when in the second state, so that the and circuit 31 outputs 1, at this time, the backlight enable signal is 0, and the input of the backlight circuit 50 is at a high level, so that the backlight circuit 50 can be started.
When the switching controller 10 does not receive the HDMI signal transmitted by the local display card or the HDMI signal transmitted by the external device, the first control signal is 0, no matter what state the target switch 20 is in, the output terminal of the and circuit 31 is 0, and the backlight enable signal is 0 at this time, so the input of the backlight circuit 50 is low level, and the backlight circuit 50 is not started.
In one embodiment of the present invention, the trigger circuit 30 may include:
an and circuit having a first input terminal for receiving a first control signal sent by the switching controller 10 and a second input terminal connected to the target switch 20;
an or gate circuit having a first input terminal connected to the output terminal of the and gate circuit, a second input terminal for receiving a backlight enable signal of the local display card, and an output terminal connected to the backlight circuit 50;

In this embodiment, an and circuit and an or circuit may be used to implement the function of the trigger circuit 30, and reference may be made to the above embodiments, and a description thereof will not be repeated.
In addition, it should be noted that the arrangement of the first resistor R1 in the foregoing embodiment is also beneficial to implement current limiting of a circuit, and protect the circuit where the first resistor R1 is located.
