Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present application more clear, the embodiments of the present application will be further described in detail with reference to the accompanying drawings.

Before the embodiments of the present application are explained in detail, the application scenarios provided in the embodiments of the present application are introduced.

In practical scenarios, displays are used in many fields. For example, in the medical field, medical staff can display image signals of medical equipment on a display, so that the medical staff can operate the medical equipment more conveniently. In the field of video monitoring, videos monitored by a camera need to be displayed on a display, so that a worker can timely know specific conditions of a monitored range. However, many displays now display a variety of image signals in a split screen manner, so that people can directly observe a variety of different image signals on one display screen, thereby maximizing the utilization value of the display. The medical staff can observe the image signals of a plurality of medical devices on one display screen. The staff in the video monitoring field can monitor a plurality of areas on one display screen simultaneously, so that the staff in the video monitoring field can manage a plurality of areas simultaneously by one person, and the working efficiency is higher.

The existing display for split-screen display generally has different formats of input image signals due to different interfaces of input ends, and the main control chip can receive the image signals of different formats, transmit the image signals to the display screen, and display the image signals through the split screen of the display screen. However, the number of input terminals on the main control chip of the conventional display is limited, and when there are image signals of various formats to be displayed in a split screen manner, the main control chip often cannot access the image signals of all formats, and thus the image signals of various formats cannot be displayed in a split screen manner on the display screen. Therefore, the embodiment of the application provides a display capable of receiving image signals with different signal formats and displaying the image signals with different formats in a split screen manner.

The display provided in the embodiments of the present application is explained in detail below.

Fig. 1 is a schematic structural diagram of a display provided in an embodiment of the present application. As shown in fig. 1, the display 100 includes a display screen 101 and one or more signal selection circuits 102.

Each of the one or more signal selection circuits 102 includes a plurality of input terminals 1021 and at least one output terminal 1022, and any one of the output terminals 1022 of each signal selection circuit 102 is connected to the display screen 101. One input terminal 1021 of each signal selection circuit 102 is used for inputting one image signal, and each signal selection circuit 102 is used for selecting at least one image signal from the image signals input from the plurality of input terminals 1021 to output from the output terminal 1022. The display screen 101 is used to display the image signals output by each signal selection circuit 102 of the one or more signal selection circuits 102. At least two of the respective input terminals 1021 of each signal selection circuit 102 are used for inputting image signals of different formats.

That is, the display 100 in the embodiment of the present application includes a display screen 101 and one or more signal selection circuits 102. The one or more signal selection circuits 102 have inputs 1021 for inputting video signals of multiple different formats, and outputs 1022 for selecting at least one video signal to be displayed, so that the video signal to be displayed is displayed on the display screen 101 through connection with the display screen 101.

The one or more signal selection circuits 102 may include four input terminals 1021 and two output terminals 1022, or may include three input terminals 1021 and two output terminals 1022. The display screen 101 may display the image signals output by one or more signal selection circuits 102, may display image signals of two formats, and may also display image signals of three different formats, which is not limited in this application.

The display screen 101 includes a plurality of display areas, and each display area is used for displaying the image signal output from one output terminal 1022 of one signal selection circuit 102. When the image signals of a plurality of different formats need to be displayed in a split screen mode, each display area can display the image signals of one format, so that the image signals of the plurality of different formats can be displayed simultaneously.

Specifically, the different formats of the image signals include any format of DVI (Digital Visual Interface), VGA (Video Graphics Array), SOG (Sync On Green, Green synchronous signal Interface), HDMI (High Definition Multimedia Interface), DP (Display Port), and SDI (Serial Digital Interface).

As an example, the signal selection circuit 102 may include two input terminals 1021 and one output terminal 1022. At this time, if it is desired to realize the effect that image signals of four different formats, such as VGA, SDI, HDMI, DVI formats, are simultaneously displayed on the display screen, four such signal selection circuits 102 are required. The input end 1021 of each signal selection circuit 102 can input two formats of image signals, which can be any one of the four formats, or other formats, and only the input end 1021 of each signal selection circuit 102 needs to include one of the four formats, that is, the input ends 1021 of the four signal selection circuits 102 respectively have one format of the image signals to be displayed.

As for any one of the four signal selection circuits 102, as shown in fig. 2, any two of the four signal selection circuits can select to input any signal, and if the output terminal 1022 of one of the signal selection circuits 102 outputs the VGA format image signal 1 and the output terminal 1022 of the other signal selection circuit 102 outputs the SDI format image signal 2, the output terminal 1022 of the third signal selection circuit 102 selects other input signals that are not selected to be input simultaneously with the signal 1 and the signal 2, that is, the output terminal 1022 of the third signal selection circuit 102 selects image signals in formats other than the VGA and SDI formats. If the two input terminals 1021 of the third signal selection circuit 102 are VGA and HDMI format video signals, the third signal selection circuit 102 outputs the HDMI format video signal 3 at the output terminal 1022. Similarly, the output terminal 1022 of the fourth signal selection circuit 102 selects another input signal that is not selected to be input simultaneously with the selection of (signal 1 and signal 2), or (signal 1 and signal 3), or (signal 2 and signal 3), that is, the output terminal 1022 of the fourth signal selection circuit 102 should output the image signal with the format different from the three formats output by the output terminals 1022 of the three signal selection circuits 102. If the two input terminals 1021 of the fourth signal selection circuit 102 are the DVI and SDI format video signals, respectively, the fourth signal selection circuit 102 outputs the DVI format video signal 4 at the output terminal 1022. Thus, the image signals 1, 2, 3, and 4 of different formats output from the output terminal 1022 of each signal selection circuit 102 can be displayed on the display screen 101 in a split screen manner.

The display area of the image signals output from the four signal selection circuits 102 on the display screen 101 is also not fixed. As shown in fig. 2, the image signal 1 output from the first signal selection circuit 102 may be displayed in the upper left display region, the image signal 2 output from the second signal selection circuit 102 may be displayed in the upper right display region, the image signal 3 output from the third signal selection circuit 102 may be displayed in the lower left display region, and the image signal 4 output from the fourth signal selection circuit 102 may be displayed in the lower right display region. The display areas of the image signals 1, 2, 3, and 4 output by the four signal selection circuits 102 on the display screen 101 may also be arbitrarily arranged, and it is only necessary that the display screen 101 can display all the image signals to be displayed in a split-screen manner.

Fig. 3 is a schematic structural diagram of another display provided in an embodiment of the present application. The display further includes a second signal selection circuit 103 based on the structure shown in fig. 1. The second signal selection circuit 103 includes a plurality of input terminals 1031 and at least two output terminals 1032, one output terminal 1032 of the second signal selection circuit 103 is connected to one input terminal 1021 of the first signal selection circuit 102, and the other output terminal 1032 of the second signal selection circuit 103 is connected to the display screen 101. At least two input terminals 1031 of the plurality of input terminals 1031 of the second signal selection circuit 103 are used to input image signals of different formats. The first signal selection circuit 102 is any one of the one or more signal selection circuits 102 shown in fig. 1.

Illustratively, different types of signal selection circuits 102 may be connected in series, thereby performing multi-stage transmission of image signals. Any one of the signal selection circuits 102 is used as the first signal selection circuit 102, such as the first signal selection circuit 102 including two input terminals 1021 and one output terminal 1022. The second signal selection circuit 103 comprises a plurality of input terminals 1031 and at least two output terminals 1032, such as four input terminals 1031 and two output terminals 1032. The image signals of four formats are input through the input terminal 1031 of the second signal selection circuit 103, the image signals of two formats are selectively output at the output terminal 1032, one output terminal 1032 of the second signal selection circuit 103 is connected with one input terminal 1021 of the first signal selection circuit 102, so that the image signals at the output terminal 1032 can be transmitted to the first signal selection circuit 102 as the input terminal 1021 of the first signal selection circuit 102, then the first signal selection circuit 102 selects the image signals of any format as the image signals output at the output terminal 1021, and finally the output image signals are displayed on the display screen 101.

As one example, the display includes a core board on which a master control chip is configured. The main control chip is connected with the display screen, and the output ends of one or more signal selection circuits are connected with the main control chip. The main control chip is used for controlling the image signals output by the output ends of the one or more signal selection circuits to be displayed on a display screen. One or more signal selection circuits are disposed on a core board of the display.

That is, one or more signal selection circuits and a master control chip are both disposed on the core board. One or more signal selection circuits on the core board output image signals with different formats, and then the image signals are transmitted to the main control chip, and the image signals output by the output ends of the one or more signal selection circuits are displayed on the display screen through the main control chip.

As another example, the display includes a core board on which a main control chip is disposed, a terminal, and an inter-circuit board connection member. The main control chip is connected with the display screen. And part or all of the one or more signal selection circuits are arranged on a terminal board of the display, and the output ends of the signal selection circuits arranged on the terminal board of the display are connected with the main control chip through the connecting component between the circuit boards.

In other words, it is also possible to dispose a part of the signal selection circuits among the plurality of signal selection circuits on the core board of the display, and a part of the signal selection circuits on the terminal board of the display. The image signals output by the output ends of the signal selection circuits on the core board are directly transmitted to the main control chip, the output ends of the signal selection circuits on the terminal board are connected with the main control chip through the connecting parts among the circuit boards, the image signals output by the output ends of the signal selection circuits on the terminal board are transmitted to the main control chip through the connecting parts among the circuit boards, and then the image signals output by the output ends of the signal selection circuits are displayed on the display screen through the main control chip.

Or, the plurality of signal selection circuits can be all deployed on a terminal board of the display, the output ends of the signal selection circuits are connected with the main control chip through the inter-circuit-board connecting component, the image signals output by the output ends of the signal selection circuits on the terminal board are transmitted to the main control chip through the inter-circuit-board connecting component, and the image signals output by the output ends of the plurality of signal selection circuits are displayed on the display screen through the main control chip.

For a third signal selection circuit in the one or more signal selection circuits, the formats of the image signals output by the output end of the third signal selection circuit are all reference formats, the third signal selection circuit further comprises a signal format conversion circuit, at least one input end of the third signal selection circuit is connected with the signal format conversion circuit, the signal format conversion circuit is used for converting the format of the image signals input by the connected input end into the reference format, and the third signal selection circuit is any one of the one or more signal selection circuits.

The one or more signal selection circuits are one or both of an HDMI 4-to-2 chip and an HDMI 2-to-1 chip, but of course, the one or more signal selection circuits may also be other chips. The reference format of the image signal output from the output terminal of the third signal selection circuit is illustratively the HDMI format. The different image signal formats of the input end of the equipment are all converted into the reference format HDMI through the signal format conversion circuit, and then the image signals converted into the HDMI format are displayed on the display screen through the main control chip.

For example, the signal selection circuit 103 in the display shown in fig. 3 may be disposed on a terminal board, and a plurality of signal selection circuits 102 may be disposed on a board of the board, constituting the display shown in fig. 4.

In a possible implementation manner, the main control chip further includes a signal input terminal, and the signal input terminal is used for inputting an image signal in one format.

Specifically, the image signal in a certain format in the signal input end may be directly input to the main control chip, and the image signal is displayed on the display screen through the main control chip, where the format of the image signal input by the signal input end is any one, and may be the image signal in the HDMI format, and may also be the image signal in the DP format, which is not limited in this embodiment of the present application. For example, as shown in fig. 4, an image signal in DP format of a signal input terminal may be input to the main control chip.

In another possible implementation manner, one or more signal format conversion circuits and one or more signal input ends in one-to-one correspondence with the one or more signal format conversion circuits are further disposed on the terminal board, the one or more signal format conversion circuits are connected with the main control chip, and any one of the one or more signal input ends is used for inputting an image signal in one format.

Specifically, the image signals of each format input by one or more input terminals can be converted into a reference format by one or more signal format conversion circuits corresponding to the one or more input terminals, and then input to the main control chip, so as to be displayed on the display screen. The format of the image signal input to the one or more signal input terminals may be any one, and may be an HDMI format image signal or a DP format image signal. The one or more signal format conversion circuits convert different formats of the image signal into a reference format, where the reference format may be an HDMI format, a DP format, or another format, and the embodiment of the present application is not limited thereto. For example, as shown in fig. 4, image signals in other formats in the terminal block 2 may be converted into DP format by the signal format conversion circuit and then input to the main control chip.

As an example, as shown in fig. 4, to split display image signals of four different formats on a display screen, two different types of signal selection circuits may be selectively disposed on a core board, one of the two different types being a two-input-end first signal selection circuit and the other being a 1-out-of-2 chip. And one is a second signal selection circuit with four input ends and two output ends, and the second signal selection circuit can be a 2-out-of-4 chip. A second signal selection circuit, i.e., a 2-out-of-4 chip, is also disposed on the terminal board 1. The signal format conversion circuit is used for converting image signals of different formats of equipment into an HDMI format, then a plurality of image signals of the HDMI format at the output end of the signal format conversion circuit are respectively used as the input ends of two 2-from-4 chips, and the two 2-from-4 chips selectively and respectively output two image signals. Two image signals output by a 2-from-4 chip on the core board are directly used as two input ends of the main control chip. One output end of the 2-from-4 chip on the terminal board 1 is also directly connected with the main control chip and is used as one input end of the main control chip. The other output end of the 2-from-4 chip is connected with the 1-from-2 chip and is used as two inputs of the 1-from-2 chip together with image signals of other formats, one image signal is selectively output through the 1-from-2 chip, and then the image signal is used as one input end of the main control chip, so that various image signals are transmitted to a display screen together with other three input ends on the main control chip, and the four image signals are displayed on the display screen in a split screen mode. That is, there may be nine formats of image signals as input at the input end of the display, and after the selection of the 1-from-2 chip and the 2-from-4 chip, there are four formats of image signals as the input end of the main control chip, and then the image signals are displayed on the display screen in a split screen manner.

Also, image signals of a plurality of different formats, for example, four DVI format image signals, three DVI format and one other format image signals, two DVI format and two other format image signals, or one DVI format and three other format image signals, etc., may be displayed on the display screen in divided screens. If the image signals of three DVI formats and one other format are displayed on the display screen in a split screen mode, any two of the image signals of the four formats can be selected at the output end of the 2-from-4 chip of the machine core board, such as the image signals of the two DVI formats, in this way, one output end of the 2-from-4 chip on the terminal board 1 can only output one of the remaining two formats, such as the image signal of the other DVI format, the output end of the 1-from-2 chip at the moment can be only the image signal of the DVI format, the 1-from-2 chip outputs the image signal of the other format, and finally, the main control chip randomly arranges the image signals of the four formats and displays the image signals on the display screen in a split screen mode. The display area of the four image signals on the display screen may be as shown in fig. 1, for example, two image signals output by the 2-from-4 chip on the core board may be arranged at the upper left and lower left, an image signal output by the 2-from-4 chip on the terminal board 1 may be arranged at the lower right, and an image signal output by the 1-from-2 chip may be arranged at the upper right, and the arrangement position of these image signals is not fixed, which is not limited in this embodiment.

The connection method between the 2-from-1 chip and the 4-from-2 chip and the main control chip is as shown in fig. 5, the main control chip can directly display the image signals of the output ends of the signal selection circuits, namely the 2-from-1 chip and the 4-from-2 chip, on a display screen, and at the moment, only one or more signal selection circuits, namely the output ends of the 2-from-1 chip and the 4-from-2 chip, are directly connected with the main control chip. If the main control signal directly receives the image signal output by the output end of the 2-from-4 chip, the image signal of one output end of the 2-from-4 chip, such as the signal 2, can be used as the input end of the main control chip, and then the image signal is displayed on the display screen. Or the image signal can be output through a 4-to-2 chip, and then the image signal output by the 4-to-2 chip is selected by a 1-to-2 chip, and then is finally displayed on the display screen as the input end of the main control chip. At this moment, when a chip of 2-to-1 is passed through, a control signal is set by a GPIO interface (General Purpose Input Output) of the main control chip, that is, a high level or a low level is set, if the main control chip sets the control signal to be the high level, that is, the Input signal 3 of the chip of 2-to-1 is used as the Input end of the main control chip, if the main control chip sets the control signal to be the low level, that is, the control signal is 0, an image signal Output by one Output end of the chip of 2-to-4 is used, if the Output signal 1 is used as the Input end of the main control chip, and then the image signal is displayed on the display screen.

The embodiment of the application also provides a terminal, which comprises a display and a controller. The controller is used for responding to the detection of a signal setting instruction for the target signal selection circuit, determining a target input end from a plurality of input ends of the target signal selection circuit, and outputting the image signal received from the target input end to the display screen from the output end so that the display screen displays the image signal input from the target input end.

Wherein the display is the display as explained in detail above. The controller is configured to respond to a signal setting instruction detected for the target signal selection circuit, that is, the controller is configured to receive an instruction set by the main control chip to the target signal selection circuit to which the image signal belongs when receiving the image signal, such as the control signal set by the main control chip in the above example. The target signal selection circuit determines the image signal to be received by the main control chip from a plurality of input ends of the target signal selection circuit by receiving the control signal, namely, the image signal is output to the display screen from an output end, so that the display screen displays the image signal.
