[0032] To make the objectives, technical solutions, and advantages of the present application clearer, the following will optionally describe in detail the embodiments of the present application with reference to the accompanying drawings.

[0033] The inventors of the present application have conducted research and found that existing professional display devices usually use an FPGA (Field Programmable Gate Array) chip to process professional video interfaces and dedicated picture quality engines, while the control and display of the human-machine interaction interface represented by the OSD menu are not suitable for FPGA chip processing. Existing display devices often separately set up CPU (Central Processing Unit) chips, MCU (Microcontroller Unit) chips, and SOC chips with video interfaces, develop a control system for the OSD menu in the above chips, display the interaction interface, and transmit the OSD menu information to the FPGA chip through an interface. The FPGA chip fuses the OSD menu information with the video information and displays it on the display panel.

[0034] However, existing CPU chips, MCU chips, and SOC chips all need to set up a separate channel for transmitting OSD menu information to avoid interference between the OSD menu information and the video information transmitted by the SOC. However, separately opening the transmitted menu will increase the complexity of the internal structure of the CPU chip, MCU chip, or SOC chip, thereby increasing the cost of the display device.

[0035] The information transmission method, device, and display device provided by the present application aim to solve the above technical problems in the prior art.

[0036] The following will specifically describe in detail the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems with specific embodiments.

[0037] An embodiment of the present application provides a display device. The schematic structural diagram of the display device is as Figure 1 shown and includes: a first processor 10, configured to receive an instruction signal; determine whether to occupy the display channel 11 of the first processor 10 according to the instruction signal; when it is determined to occupy the display channel 11, transmit an information frame carrying a first information corresponding to the instruction signal through the display channel 11, and transmit an image frame carrying image information through the display channel 11 for superimposed display; the first information is auxiliary information other than the image information.

[0038] In the display device provided in the embodiment of the present application, when the first processor 10 determines to occupy the display channel 11 of the first processor 10 according to the instruction signal, the first processor 10 transmits an information frame carrying the first information corresponding to the instruction signal through the display channel 11, and transmits an image frame carrying image information through the display channel 11 for superimposed display, so that the display channel 11 of the first processor 10 can transmit both the information frame of the first information and the image frame of the image information, which can avoid separately setting a transmission channel for the information frame of the first information in the first processor 10, is beneficial to simplifying the internal structure of the first processor, and thus is beneficial to reducing the cost of the display device.

[0039] In the embodiment of the present application, the display device includes a first processor 10. The first processor 10 is configured to receive an instruction signal and determine whether to occupy the display channel 11 of the first processor 10 according to the instruction signal. When it is determined to occupy the display channel 11, the first processor 10 transmits an information frame carrying the first information corresponding to the instruction signal through the display channel 11, and transmits an image frame carrying image information through the display channel 11 for superimposed display, so that the first processor 10 with only one display channel can simultaneously transmit the information frame of the first information and the image frame of the image information.

[0040] It should be noted that in the embodiment of the present application, the user can send an instruction signal to the first processor 10 of the display device through a remote controller, a button or other remote control devices.

[0041] In an embodiment of the present application, the display device further includes: a second processor 20, communicatively connected to the first processor 10 through the display channel 11; and a display panel 30, communicatively connected to the second processor 20.

[0042] In the embodiment of the present application, the second processor 20 is communicatively connected to the first processor 10 through the display channel 11. The second processor 20 is configured to receive and process the superimposed information frame carrying the first information corresponding to the instruction signal and the image frame carrying image information transmitted through the display channel 11, and output the processed information and image frame to the display panel 30 for display, so that the display panel 30 simultaneously displays the superimposed first information and the image of the image information.

[0043] It should be noted that the second processor 20 also includes an interface connected to other video image transmission devices or video device processing devices. When the first processor 10 receives an instruction signal sent by the user, if the display channel 11 of the first processor 10 is switched out, that is, the image frame carrying image information is not transmitted through the first processor 10. At this time, the display channel 11 of the first processor 10 is only used to transmit the information frame carrying the first information corresponding to the instruction signal. After receiving the information frame of the first information and the video image frame transmitted through other interfaces, the second processor 20 superimposes and processes the two and then sends them to the display panel 30 for display.

[0044] In the embodiment of the present application, the display channel 11 of the first processor 10 can transmit both the information frame carrying the first information corresponding to the instruction signal and the image frame carrying the image information, and can also separately transmit the information frame carrying the first information corresponding to the instruction signal. In the embodiment of the present application, the first information is auxiliary information other than the image information, such as OSD menu information, volume bar, etc.

[0045] In an embodiment of the present application, the first processor 10 includes a SOC chip, and the second processor 20 includes an FPGA chip. The SOC chip is communicatively connected to the FPGA chip through at least one display channel among MIPI, eDP, or LVDS.

[0046] Specifically, when the SOC chip receives an instruction signal sent by the user through a remote control, a button, or other remote control devices, the SOC chip determines whether to occupy the display channel of the SOC chip according to the instruction signal. When the SOC chip determines to occupy the display channel, the SOC chip transmits the information frame carrying the first information corresponding to the instruction signal through the display channel, and transmits the image frame carrying the image information through this display channel to the FPGA chip for superimposed display. That is, the SOC chip in the embodiment of the present application can achieve simultaneous transmission of the information frame of the first information and the image frame of the image information with only one display channel, thereby reducing the internal structure of the SOC chip and further reducing the cost of the display device.

[0047] In the embodiment of the present application, the display channel of the SOC chip includes any one type of interface among MIPI (Mobile Industry Processor Interface), eDP (Embedded Display Port), or LVDS (Low-Voltage Differential Signaling). Those skilled in the art can select and set different specifications of the display channel according to the actual application scenario and application requirements of the display device.

[0048] Based on the same inventive concept, an embodiment of the present application provides an information transmission method, and the schematic flowchart of this method is as shown in Figure 2 and the method includes:

[0049] S201, receiving an instruction signal.

[0050] Optionally, the first processor 10 receives the instruction signal sent by the user through a remote controller, a button, or other remote control devices.

[0051] S202, determining whether to occupy the display channel of the first processor according to the instruction signal.

[0052] Optionally, the first processor 10 determines whether to occupy the display channel 11 of the first processor 10 according to the instruction information sent by the user.

[0053] S203, when it is determined to occupy the display channel, transmitting an information frame carrying the first information corresponding to the instruction signal through the display channel, and transmitting an image frame carrying image information through the display channel for superimposed display; the first information is auxiliary information other than the image information.

[0054] Optionally, when the first processor 10 determines to occupy the display channel 11, transmitting an information frame carrying the first information corresponding to the instruction signal through the display channel 11, and transmitting an image frame carrying image information through the display channel 11 for superimposed display; the first information is auxiliary information other than the image information.

[0055] In the information transmission method provided by the embodiment of the present application, when it is determined to occupy the display channel 11 of the first processor 10 according to the instruction signal, an information frame carrying the first information corresponding to the instruction signal is transmitted through the display channel 11, and an image frame carrying image information is transmitted through the display channel 11 for superimposed display, so that the display channel 11 of the first processor 10 can simultaneously transmit the information frame of the first information and the image frame of the image information, avoiding separately setting a transmission channel for transmitting the information frame of the first information in the first processor 10, simplifying the internal structure of the first processor, and thus reducing the cost of the display device.

[0056] As shown in Figure 3 is the schematic flowchart of another information transmission method provided by the embodiment of the present application, and the method includes:

[0057] S301, the first processor 10 receives an instruction signal.

[0058] Specifically, the first processor 10 receives the instruction signal sent by the user through a remote controller, a button, or other remote control devices.

[0059] S302, the first processor 10 determines whether to occupy the display channel 11 of the first processor 10 according to the instruction signal; if so, execute S303, otherwise execute S304.

[0060] Specifically, the first processor 10 determines whether to occupy the display channel 11 of the first processor 10 according to the instruction information sent by the user.

[0061] S303, transmit an information frame carrying the first information corresponding to the instruction signal through the display channel 11, and transmit an image frame carrying image information through the display channel 11 for superimposed display; the first information is auxiliary information other than image information.

[0062] Specifically, when the first processor 10 determines to occupy the display channel 11, the first processor 10 transmits an information frame carrying the first information corresponding to the instruction signal through the display channel 11, and transmits an image frame carrying image information through the display channel 11, and outputs the superimposed information frame and image frame for display; the first information is auxiliary information other than image information, such as OSD menu information, volume bar, etc.

[0063] S304, output the first information through the display channel 11 of the first processor 10.

[0064] When the first processor 10 determines to switch out of the display channel 11 of the first processor 10, that is, when the image information for displaying images or videos, etc. is not transmitted through the display channel 11 of the first processor 10, only the first information is output through the display channel 11 of the first processor 10, that is, only information such as OSD menu information, volume bar, and display channel identifier is transmitted through the display channel 11.

[0065] In the information transmission method provided in the embodiments of the present application, when it is determined according to the instruction signal to occupy the display channel 11 of the first processor 10, an information frame carrying the first information corresponding to the instruction signal is transmitted through the display channel 11, and an image frame carrying image information is transmitted through the display channel 11 for superimposed display, so that the display channel 11 of the first processor 10 can transmit the information frame of the first information and the image frame of the image information at the same time; when the first processor 10 determines to switch out of the display channel 11 of the first processor 10, at this time the display channel 11 is only used to output the first information. Thus, through the first processor 10 with only one transmission channel, the first information can be transmitted alone, and the information frame of the first information and the image frame of the image information can be transmitted at the same time, simplifying the internal structure of the first processor, thereby reducing the cost of the display device.

[0066] For the convenience of demonstrating the information transmission method provided in the embodiments of the present application, combined with Figure 4 an explanation of the information transmission method is given. Figure 4Schematic diagram of another display device provided by an embodiment of the present application. When the first processor 10 determines to switch out the display channel 11 of the first processor 10, that is, when the image information for displaying images or videos, etc. is not transmitted through the display channel 11 of the first processor 10, only the first information is output through the display channel 11 of the first processor 10. Specifically, as Figure 4 shown, the first processor 10 generates corresponding first information according to the instruction information sent by the user, and sends an information frame carrying the first information to the second processor 20 through the display channel 11. The second processor 20 simultaneously receives the image information such as display images or videos transmitted through interfaces such as HDMI (High-Definition Multimedia Interface) 2.1 or SDI (Serial Digital Interface). After processing the image information and the information frame carrying the first information, the second processor 20 outputs it to the display panel 30 for display. Figure 4 The expression in Figure 4 represents the image information such as display images or videos. The OSD menu information in the display screen of the display panel 30 is located in the lower right corner of the display screen.

[0067] It should be noted that the HDMI 2.0, IP (RJ45) (representing the Internet Protocol interface of the Registered Jack 45 type), and USB (Universal Serial Bus) interfaces on the left side of the first processor 10 are all used to transmit the image information such as display images or videos.

[0068] In an embodiment of the present application, the method of transmitting an information frame carrying the first information corresponding to the instruction signal and transmitting an image frame carrying the image information through the display channel 11 in step S303 for superimposed display is specifically as follows:

[0069] In an embodiment of the present application, the display channel 11 includes three signal transmission channels, and outputting an information frame carrying the first information corresponding to the instruction signal through the display channel 11 includes: transmitting the luminance component information of the first information through at least one signal transmission channel, and transmitting the chrominance component information of the first information through another signal transmission channel.

[0070] Optionally, the first information includes first menu information and second menu information; the three signal transmission channels include a first signal transmission channel, a second signal transmission channel, and a third signal transmission channel; and, transmitting the luminance component information of the first information through at least one signal transmission channel and transmitting the chrominance component information of the first information through another signal transmission channel includes: transmitting the luminance component information of the first menu information through the first signal transmission channel, transmitting the luminance component information of the second menu information and the chrominance identifier of the first menu information or the chrominance identifier of the second menu information through the second signal transmission channel; transmitting the first chrominance component information and the second chrominance component information of the first menu information or the second menu information through the third signal transmission channel. In the embodiments of the present application, the first menu information includes an OSD menu, and the second menu information includes auxiliary information such as a volume bar and a display channel identifier.

[0071] It can be understood that in the embodiments of the present application, the luminance component information of the first menu information can be transmitted through the first signal transmission channel, the chrominance identifier of the first menu information can be transmitted through the second signal transmission channel, and the first chrominance component information and the second chrominance component information of the first menu information can be transmitted through the third signal transmission channel; or the luminance component information of the second menu information and the chrominance identifier of the second menu information can be transmitted through the second signal transmission channel, and the first chrominance component information and the second chrominance component information of the second menu information can be transmitted through the third signal transmission channel.

[0072] In the prior art, the Y channel is used to transmit luminance component information, and the U channel and the V channel are used to transmit chrominance information. In the embodiments of the present application, the three signal transmission channels include the Y channel, the U channel, and the V channel. When the first processor 10 determines that the U channel transmits the chrominance identifier of the first menu information, the Y channel transmits the luminance component information of the first menu information, and the V channel transmits the first chrominance component information and the second chrominance component information of the first menu information.

[0073] Those skilled in the art understand that since there are few light and dark transitions in the information of patterns such as the volume bar and the display channel identifier, monochromatic display is generally used. Therefore, the luminance component information of the second menu information can be transmitted through the U channel. At the same time, since the information of patterns such as the OSD menu, the volume bar, and the display channel identifier only includes simple color matching, the chrominance component information of the V channel can be compressed, so that the V channel transmits the first chrominance component information and the second chrominance component information of the first menu information or the second menu information at the same time.

[0074] Specifically, as Figure 5 shown, Figure 5In the present application embodiment, the bit information transmitted by each channel is represented by a rectangle. In this embodiment, the U channel transmits a chrominance identifier of 1 bit (binary digit). When the first processor 10 determines that the chrominance identifier transmitted by the U channel is the chrominance identifier of the first menu information, the first processor 10 controls all 8 bits of the Y channel to transmit the luminance component information of the first menu information, 4 bits of the V channel to transmit the first chrominance component information of the first menu information, and the remaining 4 bits of the V channel to transmit the second chrominance component information of the first menu information.

[0075] Optionally, when the first processor 10 determines that the chrominance identifier transmitted by the U channel is the chrominance identifier of the second menu information, the first processor 10 controls the remaining 7 bits of the U channel to transmit the luminance component information of the second menu information, 4 bits of the V channel to transmit the first chrominance component information of the second menu information, and the remaining 4 bits of the V channel to transmit the second chrominance component information of the second menu information. Those skilled in the art understand that for auxiliary information such as a volume bar and a display channel identifier, in order to further simplify, it can be controlled that only the remaining 7 bits of the U channel transmit the luminance component information of the second menu information, and the V channel does not transmit the chrominance component information, that is, only the luminance component information of the second menu information is transmitted, so that the second menu information such as a volume bar and a display channel identifier is displayed in black and white.

[0076] In an embodiment of the present application, an information frame carrying the first information corresponding to the instruction signal is output through the display channel 11, including: carrying one of the first menu information and the second menu information of the first information in an odd-numbered information frame, and carrying the other of the first menu information and the second menu information of the first information in an even-numbered information frame, and transmitting through the display channel 11.

[0077] In the embodiment of the present application, by carrying one of the first menu information and the second menu information of the first information in an odd-numbered information frame and carrying the other of the first menu information and the second menu information of the first information in an even-numbered information frame, time-division transmission of the first menu information and the second menu information is achieved, thereby effectively avoiding mutual interference between the first menu information and the second menu information. At the same time, in order to ensure the continuity of the display screen viewed by the user, in the embodiment of the present application, the number of frames transmitted per second by the display channel 11 is 30.

[0078] In an embodiment of the present application, the method of transmitting the information frame carrying the first information corresponding to the instruction signal through the display channel 11 and transmitting the image frame carrying the image information through the display channel 11 for superimposed display in the above step S303 further includes:

[0079] Determine at least two pixels in the image frame corresponding to the first information whose similarity is greater than the similarity threshold as position pixels.

[0080] Optionally, in the embodiments of the present application, the last three pixels in the image frame whose similarity is greater than the similarity threshold are determined as position pixels. Generally speaking, the pixel values of these three pixels are the same.

[0081] Carry the display position information of the first information in the image to be displayed at the position of the original image information of the position pixels in the image frame to obtain the first image frame.

[0082] Optionally, in the embodiments of the present application, the display position information of the first information in the image to be displayed is located at the position of the original image information of the position pixels in the image frame by means of writing and covering, deleting and rewriting, or writing after initialization, so as to obtain the first image frame.

[0083] The first processor 10 transmits the first image frame through the display channel 11, so that the image displayed on the display panel contains both the display screen and the screen information such as the OSD menu and the volume bar.

[0084] In an embodiment of the present application, carrying the position information of the first information in the image to be displayed at the position of the original image information of the position pixels in the image frame includes: carrying the first display position information of the first menu information of the first information and the second display position information of the second menu information of the first information at the position of the original image information of the position pixels in the image frame.

[0085] In the embodiments of the present application, in order to avoid interference between the OSD menu and auxiliary information such as the volume bar and the channel identifier in the image displayed on the display panel, and to make the OSD menu, the volume bar, and the channel identifier be displayed at different positions, it is necessary to separately set the first display position information of the first menu information and the second display position information of the second menu information, so that the first image frame transmitted by the display channel 11 contains both the first menu information and the second menu information, and the first menu information and the second menu information are displayed at different positions, avoiding interference with each other and ensuring the user experience. As Figure 6 shown, the expression in the figure represents the display screen of the display panel. The channel identifier HDMI1 in the display screen is located in the upper right corner of the display screen, and the OSD menu information is located in the lower right corner of the display screen.

[0086] Based on the same inventive concept, an information transmission device 400 provided in the embodiments of the present application, the structural framework schematic diagram of the information transmission device 400 is as Figure 7As shown in the figure, it includes: a signal receiving module 401 for receiving an instruction signal; a signal processing module 402 for determining whether to occupy the display channel 11 of the first processor 10 according to the instruction signal; when it is determined to occupy the display channel 11, an information frame carrying the first information corresponding to the instruction signal is transmitted through the display channel 11, and an image frame carrying image information is transmitted through the display channel 11 for superimposed display; the first information is auxiliary information other than image information.

[0087] The information transmission device 400 in this embodiment can execute any information transmission method provided in the embodiments of the present application, and its implementation principle is similar, which will not be elaborated here.
