Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them.

[0046] A split TV refers to a TV that is designed with the host and display screen separated. In a split TV, the image, power supply, I2C control and other signals between the host and the display screen are connected by electronic wires, among which the image signal transmission is transmitted through an HDMI-like protocol signal. Nowadays, the high-speed serial video transmission interface signal output by the host's image processing chip is not easy to transmit. In order to improve the transmission reliability, it is necessary to add a conversion chip for converting the high-speed serial video transmission interface signal to the HDMI signal on the host side, and add a reverse conversion chip for converting the HDMI to the high-speed serial video transmission interface signal on the display side.

[0047] However, the conversion chip and the reverse conversion chip are expensive, thus resulting in a high development cost for the split TV.

[0048] Therefore, how to reduce the development cost of split TVs is a technical problem that remains to be solved by those skilled in the art.

[0049] In view of the above technical problems, the present application proposes a split TV signal transmission circuit. In the split TV signal transmission circuit proposed in the present application, the present application not only ensures the normal operation of the split TV by aggregating the signal first and then decomposing it, but also avoids the high cost problem caused by the need to convert the signal in the existing solution. Therefore, the present application achieves the purpose of reducing the development cost of the split TV by aggregating the signal first and then decomposing it.

[0050] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a circuit framework corresponding to the first embodiment of the split television signal transmission circuit of the present application.

[0051] In this embodiment, the split TV signal transmission circuit includes: a host end 10, a split connection device 20 and a display end 30 connected in sequence, the host end 10 includes a first aggregation chip 101, and the display end 30 includes a second aggregation chip 301 and a display module 302 connected in sequence; wherein the first aggregation chip 101, the split connection device 20, and the second aggregation chip 301 are connected in sequence;

[0052] The first aggregation chip 101 is used to perform differential signal aggregation and low-speed signal aggregation on the image signal to be displayed, obtain an aggregated image signal, and transmit the aggregated image signal to the split connection device 20;

[0053] The split connection device 20 is used to transmit the polymerized image signal to the second polymer chip 301;

[0054] The second aggregation chip 301 is used to decompose the aggregated image signal and transmit the decomposed image signal to the display module 302 .

[0055] In one embodiment, a SOC chip (System on Chip) 102 is usually provided in the host end 10. The SOC chip 102 is connected to the above-mentioned first aggregation chip 101 and is used to output the image signal to be displayed, I2S audio, USB signal, and I2C signal to the first aggregation chip 101.

[0056] In one embodiment, the host end 10 further includes: a power board 103, the power board 103 is connected to both the first aggregation chip 101 and the split connection device 20;

[0057] The power board 103 is used to convert the input alternating current into direct current, and to supply power to the first aggregation chip 101 and the split connection device 20 based on the direct current.

[0058] It is understandable that, in order to facilitate the normal operation of each device in the host end, a power board is usually provided in the host end, and power is supplied through the power board. However, the method of connecting the power board with the split connection device adopted in the present application can not only supply power to the split connection device based on the power board, but also transfer the electric energy in the power board to the display end through the split connection device, thereby supplying power to each device in the display end. It can be seen that the method of setting a power board on the host end to supply power to all devices in the circuit in the present application can avoid the technical problem of setting a power supply on the display end resulting in a large volume of the display end, thereby achieving the effect of reducing the volume of the host end and the display end as a whole.

[0059] In one embodiment, when both the SOC chip 102 and the power board 103 exist in the split TV signal transmission circuit, the power board 103 can be connected to the split connection device 20, the SOC chip 102 and the first aggregation chip 101, and is used to supply power to the split connection device 20, the SOC chip 102 and the first aggregation chip 101. Alternatively, the power board 103 can also be indirectly connected to the first aggregation chip 101 through the SOC chip 102, thereby indirectly supplying power to the first aggregation chip 101. For the display terminal 30, the second aggregation chip 301 and the display module 302, and even other devices for assisting screen display in the display terminal are connected to the power board 103 through the split connection device. Thus, the power board 103 can supply power to all devices that need power in the split TV signal transmission circuit.

[0060] In a feasible implementation manner, the image signal to be displayed is one of a high-speed serial video transmission interface signal and a TCONLESS signal.

[0061] It should be noted that the high-speed serial video transmission interface signal refers to the signal corresponding to the VBYONE protocol, and the TCONLESS signal is the signal output by the SOC after the TCON (Timing Controller) function is integrated into the SoC.

[0062] It can be understood that the split television signal transmission circuit of the present application can be used to transmit high-speed serial video transmission interface signals, and can also be used to transmit TCONLESS signals.

[0063] Please refer to Figure 2 In a feasible implementation manner, when the image signal to be displayed is a TCONLESS signal, the display module 302 includes a display screen 3021; ​​wherein the display screen 3021 is connected to the second aggregation chip 301;

[0064] The display screen 3021 is used to output an image based on the decomposed image signal transmitted by the second aggregation chip 301 .

[0065] It is understandable that, at the display end of a traditional split TV, a TCON module is usually provided to connect to the TV screen, wherein the TCON module is used to perform timing control on the signals to be output. However, most SOC chips nowadays are integrated with the TCON function, so in theory, the TCON module in the display end can be omitted, and only the GAMMA and PM functions can be retained. However, there are currently no chips on the market that can convert TCON signals, so the TCON module in traditional split TVs cannot be omitted.

[0066] In this embodiment, the present application can output a TCONLESS signal through a SOC chip with an integrated TCON function, and then aggregate, transmit, and decompose the TCONLESS signal in sequence to directly transmit the TCONLESS signal to the display screen. Therefore, in this application, the TCON module in the traditional split TV is omitted, thereby further reducing the manufacturing cost of the TV.

[0067] Please refer to Figure 3 In a feasible implementation, when the image signal to be displayed is a high-speed serial video transmission interface signal, the display module 302 includes a timing control unit 3022 and a display screen 3021 connected in sequence; wherein the timing control unit 3022 is connected to the second aggregation chip 301;

[0068] The timing control unit 3022 is used to convert the decomposed image signal transmitted by the second aggregation chip 301 into a driving signal;

[0069] The display screen 3021 is used to output images based on the driving signal.

[0070] It can be understood that when the SOC chip 102 outputs a high-speed serial video transmission interface signal, the high-speed serial video transmission interface signal can also be transmitted to the display end 30 by first aggregating and then decomposing, so that the timing control unit 3022 (TCON control) in the display end 30 can convert the high-speed serial video transmission interface signal, thereby facilitating the display screen 3021 to output an image based on the converted signal.

[0071] Please refer to Figure 4 In a feasible implementation, the split connection device 20 includes a first connector 201 and a second connector 202 connected in sequence; the first connector 201 is connected to the first aggregate chip 101, and the second connector 202 is connected to the second aggregate chip 301;

[0072] The first connector 201 is used to transmit the aggregated image signal transmitted by the first aggregation chip to the second connector 202;

[0073] The second connector 202 is used to transmit the aggregated image signal to the second aggregation chip 301 .

[0074] It should be noted that the split connection device 20 can be split into a first connector 201 and a second connector 202, so that the first connector 201 can be connected to the host end 10, and the second connector 202 can be connected to the display end 30, and the first connector 201 and the second connector 202 can be connected to realize communication between the host end 10 and the display end 30.

[0075] Please refer to Figure 5In a feasible implementation, the first connector 201 can also be set at the host end, and the second connector 202 can be set at the display end. The present application does not limit the specific positions of the first connector and the second connector.

[0076] Furthermore, in order to improve the transmission effect of the aggregated image signal, the aggregated image signal can be transmitted as an optical fiber signal. Accordingly, when the optical fiber signal is transmitted, the first connector and the second connector can be connected by an electronic wire and an optical fiber wire.

[0077] It should be noted that one pair of differential signals output by the host requires two data pins. If the definition of the TV is 4K@60Hz ultra-high-definition transmission, eight pairs of differential signals are generally required, that is, 16 data pins. If the definition of the TV is 4K@120Hz ultra-high-definition transmission, 16 pairs of differential signals are generally required, and 32 data pins need to be set. Therefore, different pin numbers need to be set for different definition requirements.

[0078] Please refer to Figure 6 , Figure 6 This is a comparison diagram of differential signal aggregation of some pins of an embodiment of the split TV signal transmission circuit of the present application. Among them, differential signal pair 1 is DU I N1 and DUOUT1, which are aggregated into a differential signal single pin HaDu IO1, and differential signal pair 2 is DU I N2 and DUOUT2, which are aggregated into a differential signal single pin HaDu IO2; differential signal pair 3 is DUIN3 and DUOUT3, which are aggregated into a differential signal single pin HaDu IO3.... That is, for 4K@60Hz ultra-high-definition TV, there are 8 pairs of differential signals in common, and for 4K@120Hz ultra-high-definition projects, there are 16 pairs of differential signals in common. In a feasible implementation, Figure 6 The aggregation chip in the embodiment can be SG6311, and this application does not limit the model of the aggregation chip.

[0079] For example, please refer to Figure 7 , Figure 7 This is a schematic diagram of a signal receiving and sending scenario of a specific embodiment of the split TV signal transmission circuit of the present application. Figure 7 The G6210 in the figure is the optical fiber signal transceiver module, and the FPGA+Lenen is the SG6311, which refers to the aggregation chip. In addition, the SG6311 in the host end is the first aggregation chip, and the SG6311 in the display end is the second aggregation chip. Figure 7It can be seen that in the scenario of 4K@120Hz ultra-high-definition transmission, the high-speed serial video transmission interface signal (VBYONE signal) needs to be transmitted with a 16l anes optical fiber signal. In addition, in order to improve the transmission effect of the signal, after the signal is aggregated by the aggregation module, it is also necessary to send and receive through the optical fiber signal transceiver module. Then, at the display end, the G6210 module receives the optical signal, and restores it to a high-speed serial video transmission interface signal differential signal pair, I2S, I2C and other signals through the SG6311 signal conversion module, and outputs it to the module corresponding to the display screen. For example, the high-speed serial video transmission interface signal can be directly transmitted to the TCON end of the display screen. In addition, for signals that do not need to be aggregated and decomposed, signal transmission can be carried out in a traditional way. For example, the power supply can be transmitted with 6 copper wires, and the USB2.0 signal can be transmitted with 2 copper wires.

[0080] In this embodiment, the present application not only ensures the normal operation of the split TV by aggregating the signal first and then decomposing it, but also avoids the high cost problem caused by the need to convert the signal in the existing solution. Therefore, the present application achieves the purpose of reducing the development cost of the split TV by aggregating the signal first and then decomposing it.

[0081] For further information, please refer to Figure 8 Based on the various embodiments of the above-mentioned split television signal transmission circuit, a first embodiment of the split television signal transmission method of the present application is proposed.

[0082] In this embodiment, the split television signal transmission method includes:

[0083] Step S10, performing differential signal aggregation and low-speed signal aggregation on the image signal to be displayed by the first aggregation chip to obtain an aggregated image signal, and transmitting the aggregated image signal to the split connection device;

[0084] Step S20, transmitting the polymerized image signal to the second polymer chip through the split connection device;

[0085] Step S30: decomposing the aggregated image signal by a second aggregation chip, and transmitting the decomposed image signal to a display module.

[0086] It is understandable that the reason for converting the signal to be transmitted in the traditional solution is that the signal output by the SOC chip is not convenient for long-distance transmission. Therefore, the signal needs to be converted into a signal that is convenient for long-distance transmission, and then the converted signal is transmitted to the other end. However, in the present application, the signal that needs to be transmitted over a long distance is aggregated by a low-cost aggregation chip, and then the aggregated signal is transmitted to the other end. The other end decomposes the aggregated signal, which can realize the transmission of the signal without converting the signal, so that the display end of the split TV can also output the image normally. It can be seen that the split TV signal transmission method proposed in this application achieves the purpose of reducing the development cost of split TVs.

[0087] The split TV signal transmission method proposed in this embodiment adopts all the technical solutions of all the above embodiments, and therefore has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0089] Since the split TV proposed in this embodiment adopts all the technical solutions of all the above embodiments and belongs to the same technical concept, this embodiment at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
