An embodiment of the present disclosure provides a display device, and
The display device provided by the present disclosure sets the signal source end 1 and the display end 2 separately. By setting the first signal transmission module 12 at the signal source end 1 and the second signal transmission module 21 at the display end 2, the first signal transmission module 12 and the second signal transmission module 21 are connected by the optical fiber to transmit the V BY ONE data signal. Compared with the existing integrated architecture of the signal source and the display device, the thickness of the display device can be effectively reduced, the screen is thinner, and when the display device needs to be upgraded and maintained, only the signal source end device needs to be disassembled or replaced without disassembling the display device, so the maintenance cost of the display device can be effectively reduced.
The display device described in the present disclosure can be a TV or other display device with a display screen. The present disclosure only takes the TV as an example to illustrate the overall architecture and components of the display device. For example, the display device is a TV. By setting the signal source end 1 and the display end 2 separately, a split TV architecture can be formed. The split TV can meet the needs of higher resolution, the screen can be ultra-thin, and the transmission part 3 can be longer, which can be suitable for remote control screens such as projectors. The first control circuit 11 may be a mainboard. The display module may be an LCD display module or other display modules. The display module may include a backlight unit and a display unit. The backlight unit 23 obtains the first power supply signal V1 to emit light. The display unit may include a second control circuit 22. The second control circuit 22 may be a TCON board. The second control circuit 22 and the backlight unit are usually located on different circuit boards. The second control circuit 22 obtains the V BY ONE data signal for image display. The first signal transmission module 12 and the second signal transmission module 21 may be photoelectric converters (capable of photoelectric signal conversion and electro-optical signal conversion). The first signal transmission module 12 may convert the V BY ONE data signal of the signal source end 1 into an optical signal, and then transmit it to the second signal transmission module 21 through an optical fiber. The second signal transmission module 21 then converts the optical signal into a corresponding V BY ONE data signal for output, so as to display the image on the display end. Compared with the traditional use of electronic wires to transmit data signals (such as transmitting image signals based on the HDMI interface), the display device according to the present disclosure uses V BY ONE data signals to transmit image signals, and transmits V BY ONE data signals through optical fibers, which has the advantages of large signal capacity, no electromagnetic interference, wide transmission bandwidth, long transmission distance, low transmission loss, thin wire diameter, light weight, etc. On the basis of realizing the split TV architecture, the transmission line can be made longer and thinner, which is convenient for supporting the screen connection of other external devices, such as projectors, exhibition hall speakers, etc. In addition, the TCON board of the current high-definition display device mainly obtains image signals through V BY ONE data signal. Compared with the display technology that uses the HDMI interface to transmit image signals, such as the solution of using optical fiber to transmit HDMI signals, the display device according to the present disclosure directly uses optical fiber to transmit V BY ONE data signal to transmit image signal. The display device does not need to perform signal conversion, thereby reducing the use of the adapter board for converting HDMI signal to V BY ONE data signal, which can save costs, reduce space occupancy, and reduce compatibility issues, and improve the reliability of the display device.
It should be understood that the first signal transmission module 12 and the first control circuit 11 according to the present disclosure can be integrated into the same circuit board, or they can be separately set on different circuit boards. Similarly, the second signal transmission module 21 and the second control circuit 22 can be integrated on the same circuit board, or separately set on different circuit boards. These all belong to the protection scope of the present disclosure.
The present disclosure can realize the split architecture of the TV by integrating a photoelectric converter on the main board and another photoelectric converter on the TCON board of the LCD display module, without the need to set up an additional adapter board, which can save space and cost, making the display device more compact and lightweight.
The signal source end 1 of the display device of the present disclosure can be set in an audio box (external speaker) to form an independent device. When the display device needs to be repaired or upgraded, only the audio box needs to be disassembled or replaced, and the TV does not need to be replaced. Compared with the traditional integrated TV, the display device provided by the present disclosure has the advantages of low cost and high efficiency. The display device of the present disclosure uses V BY ONE data signal to transmit image signals. The V BY ONE interface has low power consumption and supports data transmission up to 4 Gbps (effective data volume reaches 3.2 Gbps), etc., which can replace the traditional LVDS interface. For a UHD 60 Hz TV panel, the V BY ONE interface only requires 18 wires ((18−2)/2−8 lane), and for a UHD 120 Hz TV panel, the V BY ONE interface only requires 34 wires ((34−2)/2=16 lane). The display device provided by the present disclosure is compatible with traditional TV mainboard, has a high degree of standardization, and the optical fiber transmission method can achieve extremely long-distance signal transmission.
The power supply part of the display device of the present disclosure is introduced below in conjunction with the accompanying drawings. As shown in
In an exemplary embodiment, the first signal transmission module is connected between the first power source module and the power line. The first power source module can be directly connected to the first signal transmission module, and the first signal transmission module is then connected to the power line; and/or, the first power source module is first connected to the first control circuit, connected to the first signal transmission module through the first control circuit, and then connected to the power line by the first signal transmission module. For example, the first power source module can output the first power supply signal V1 by directly connecting to the first signal transmission module, and the first power source module can output the third power supply signal V3 and the fourth power supply signal V4 by connecting to the first signal transmission module through the first control circuit.
The first control circuit 11 can be powered by the second power supply signal V2, and the first control circuit 11 can output a third power supply signal V3 and a fourth power supply signal V4. The third power supply signal V3 is transmitted to the display end 2, and can be configured to power the second control circuit 22 of the display end 2 (i.e., power supply for screen display), and the fourth power supply signal V4 can be configured to power the first signal transmission module 12 and the second signal transmission module 21. In an exemplary embodiment, the first power supply signal V1 can be a DC voltage signal of 200V to 400V, 2 A. In one embodiment of the present disclosure, the first power supply signal V1 is a DC voltage signal of 380V, 2 A. The first power supply signal V1 is transmitted to the display end 2 to power the backlight source in the display module 2. For example, the second signal transmission module 21 can output the first power supply signal V1 to the backlight driving board of the display module 2, and the backlight driving board then steps down the 380V voltage to 25V voltage and outputs it to the backlight source of the display module 2 to power the backlight source. The third power supply signal V3 and the fourth power supply signal V4 may be 12V voltage signals, and the current magnitudes of the third power supply signal V3 and the fourth power supply signal V4 may be different. The third power supply signal V3 may be a 12V, 4 A voltage signal, and the fourth power supply signal V4 may be a 12V, 2 A voltage signal. The third power supply signal V3 and the fourth power supply signal V4 are two independent power supply signals, and timing control may be performed by independently controlling the two power supply signals. This exemplary embodiment may utilize the existing 12V power supply port in the first control circuit 11 to output two 12V voltages as the third power supply signal V3 and the fourth power supply signal V4, respectively. In addition, in some embodiments of the present disclosure, the first power source module 13 may also output a 5V power supply signal to the first control circuit 11 for powering the related devices in the first control circuit 11 and output a 5V SB (Standby) power supply signal for providing a 5V Standby voltage to the first control circuit 11. Of course, the first power source module 13 can also output other power supply signals, such as outputting a 3.3V power supply signal to power the related devices in the first control circuit 11, etc., which depends on the power supply requirements of the active devices of the first control circuit 11, which will not be described in detail here.

The first control circuit 11 described in the present disclosure can transmit the second display control signal D2 to the first signal transmission module 12 in a variety of ways.
For example, in some embodiments, the first connector may include a first terminal, a second terminal, and a third terminal. The first terminal may include a CN1 sub-connector. The second terminal may include a CN3 sub-connector, a CN4 sub-connector, and a CN5 sub-connector. The third terminal may include a CN2 sub-connector. In some other embodiments, the first connector may include only a first terminal and a second terminal. The first terminal may include a CN1 sub-connector.

For the BL signal, ADJ signal, UART_TX signal, and UART_RX signal, please refer to the introduction of the subsequent embodiments, which will not be described in detail here.
The CN1 sub-connector, CN2 sub-connector, CN3 sub-connector, CN4 sub-connector, and CN5 sub-connector described in the present disclosure can be arranged on the same circuit board as the first signal transmission module 12.
It can be understood that the transmission of the second display control signal D2 to the first signal transmission module 11 through the CN3 sub-connector and the CN4 sub-connector in the second terminal can be compatible with those first control circuit boards without the 41-pin sub-connector, thereby improving the compatibility with the mainboard of the signal source end.

The first 8 pairs of differential voltage difference signals are transmitted by the 51-pin sub-connector, and the last 8 pairs of differential voltage difference signals are transmitted by the 41-pin sub-connector. The first display control signal D1 in the low-speed signal is transmitted by the 51-pin sub-connector, and the second display control signal D2 in the low-speed signal is transmitted by the 41-pin sub-connector.
It should be understood that the first control circuit 11 should have a terminal that cooperates with the first signal transmission module 12. In other words, in a case where the first connector includes a first terminal, a second terminal, and a third terminal, the first control circuit 11 also has a terminal that cooperates with the first terminal, a terminal that cooperates with the second terminal, and a terminal that cooperates with the third terminal. For example, the first control circuit 11 may also include CN1 sub-connector, CN2 sub-connector, CN3 sub-connector, CN4 sub-connector and CN5 sub-connector above-mentioned.
The signals transmitted by the 51-pin sub-connector and the 41-pin sub-connector in the present disclosure are described in detail below.
Table 1 is a description of the signals connected to each pin in the 51-pin sub-connector. It can be seen from Table 1 that the first sub-data signal VB1 transmitted in the 51-pin sub-connector may include 8 pairs of high-speed signals: (TX0N, TX0P), (TX1N, TX1P), (TX2N, TX2P), (TX3N, TX3P), (TX4N, TX4P), (TX5N, TX5P), (TX6N, TX6P), (TX7N, TX7P). The high-speed signal is a differential voltage difference signal and can be transmitted at a rate of several hundred Mbit/s. The first sub-data signal VB1 transmits the display data of the panel through individual channels in an AC-coupled manner. The first display control signal D1 transmitted in the 51-pin sub-connector may include 2 low-speed signals: HTPDN and LOCKN. The HTPDN signal (Hot Plug Detect Signal) is configured to feedback whether the second signal transmission module 21 is connected to the first signal transmission module 12. The LOCKN signal (Lock Clock Negative) is configured to feedback whether the TCON board decodes the clock signal output by the mainboard. The first communication signal T1 may include an SDA_P signal and an SCL_P signal. The SDA_P signal and the SCL_P signal are a group of IIC signals reserved for communication between the mainboard and the TCON board to adjust certain display parameters of the display module.
Table 2 is a description of the signals connected to each pin in the 41-pin sub-connector. It can be seen from Table 2 that the second sub-data signal VB2 transmitted in the 41-pin sub-connector can include 8 pairs of high-speed signals: (TX8N, TX8P), (TX9N, TX9P), (TX10N, TX10P), (TX11N, TX11P), (TX12N, TX12P), (TX13N, TX13P), (TX14N, TX14P), (TX15N, TX15P). The high-speed signal is a differential voltage difference signal and can be transmitted at a rate of several hundred Mbit/s. The second sub-data signal VB2 transmits the display data of the panel through individual channels in an AC coupling manner. The second display control signal D2 transmitted in the 41-pin sub-connector may include a second communication signal, a backlight control signal, a backlight adjustment signal and an asynchronous communication signal, and may specifically include 6 low-speed signals: SDA_G, SCL_G, BL, ADJ, TX, RX. Among them, SDA_G, SCL_G are the second communication signals, specifically a group of IIC signals, which are reserved for the communication between the main board at the signal source end and the TCON board at the display end, and can be configured to adjust the display parameters of other types of the display module. The second communication signal and the first communication signal described in the present disclosure can both be configured to adjust the display parameters of the display module, and the two can be configured to adjust the display parameters of different types. BL is a backlight control signal, which only outputs high and low levels. For example, when BL outputs a high level, the backlight is turned on, and when BL outputs a low level, the backlight is turned off. ADJ is a backlight adjustment signal to adjust the backlight brightness, and the backlight brightness frequency can be controlled at about 200 Hz. ADJ can be a PWM signal, and the brightness is related to the duty cycle of the ADJ signal. The higher the duty cycle, the higher the backlight brightness, and the lower the duty cycle, the lower the backlight brightness. The UART_TX signal and the UART_RX signal are asynchronous communication signals, which are reserved for the mainboard to communicate with asynchronous communication devices (such as FPGA, camera, etc.), and can be configured to adjust screen display parameters, backlight parameters, sound parameters, etc. The asynchronous communication signal included in the second display control signal described in the present disclosure can be a UART_TX signal or a UART_RX signal. For example, the first control circuit communicates with the asynchronous communication device of the display end by sending the UART_TX signal, and the UART_RX signal is the signal fed back by the asynchronous communication device of the display end to the first control circuit.
In other embodiments, the first control circuit can also output GPIO2 signal and GPIO3 signal to the first signal transmission module. The GPIO2 signal and GPIO3 signal are power control signals. For example, when the power control signal is at a high level, the 12V power supply can be turned on. The GPIO2 signal can be configured to control the 12V power supply of the screen, and the GPIO3 signal can be configured to control the 12V power supply other than the screen. For example, the signal source end may include a switch control circuit, and the switch control circuit may be arranged on the same circuit board as the first signal transmission module. The first control circuit may control the switch control circuit by outputting a GPIO2 signal to control the output of the third power supply signal V3, and/or, control the switch control circuit by outputting a GPIO3 signal to control the output of the fourth power supply signal V4. The control principle of the GPIO2 signal and the GPIO3 signal may be referred to the introduction of the subsequent embodiments.
In addition, the first signal transmission module may also transmit the detection level signal VCAB_DET to the first control circuit 11 through the 41-pin sub-connector. The detection level signal VCAB_DET may be a high or low level signal, which is configured to determine whether the display end 2 is connected to the signal source end 1. For example, when the display end 2 is connected to the signal source end 1, CAB_DET may output a low level signal, and when the display end 2 is not connected to the signal source end 1, CAB_DET may output a high level signal.
The hot-plug function of the power interface of the display device of the present disclosure is described below. The display device may include a plurality of switch modules. The switch module may be arranged on the same circuit board as the first signal transmission module 12, and the switch module may control whether the connected voltage output end outputs a voltage signal according to the detection level signal VCAB_DET. As shown in
For example, when the detection level signal VCAB_DET is at a low level, the first switch unit QN6 is turned on, so that the control terminal of the second switch unit QN5 is at a low level; the second switch unit QN5 is turned on, so that the control terminal of the third switch unit QN4 is at a low level; and the third switch unit QN4 is turned on, and the power supply signal is output through the voltage output end. On the contrary, when the detection level is at a high level, the first switch unit QN6 is turned off, so that the control terminal of the second switch unit QN5 is at a high level; the second switch unit QN5 is turned off, so that the control terminal of the third switch unit QN4 is at a high level; and the third switch unit QN4 is turned off, thereby controlling the voltage output end to stop outputting the power supply signal.
In an exemplary embodiment, the first switch unit QN6 and the second switch unit QN5 may be P-type transistors. The third switch unit QN4 may include a PMOS transistor. The voltage divider circuit may be a resistor voltage divider circuit. The voltage divider circuit connected to the first terminal of the first switch unit QN6 may include a first resistor R1. One terminal of the first resistor R1 is connected to the power supply signal Vm to be output, and the other terminal is connected to the first terminal of the first switch unit QN6. The voltage divider circuit connected to the first terminal of the second switch unit QN5 may include a second resistor R2. A first terminal of the second resistor R2 is connected to the power supply signal Vm to be output, and a second terminal is connected to the first terminal of the second switch unit QN5. The resistance value in the resistor voltage divider circuit can be determined according to the parameters of the transistor. In addition, since the third switch unit QN4 needs to output a power supply voltage, a filter capacitor can be set at the first terminal and the second terminal of the third switch unit QN4. The filter capacitor may specifically include a first capacitor C1, a third capacitor C3 and a fourth capacitor C4. The first terminal of the first capacitor C1 is connected between the first terminal of the third switch unit QN4 and the power supply signal Vm to be output, and the second terminal of the first capacitor C1 is grounded. The third capacitor C3 and the fourth capacitor C4 are connected in parallel and one terminal is connected between the second terminal of the third switch unit QN4 and the voltage output end, and the other end is grounded. By setting the filter capacitor, interference signals can be filtered out and stable voltage signals can be output. In addition, the switch module may also include a third resistor R3, a fourth resistor R4, a start-up slow start module and a shutdown discharge module. One terminal of the third resistor R3 is connected to the power supply signal Vm to be output, and the other terminal is connected to the control terminal of the first switch unit QN6. One terminal of the fourth resistor R4 is connected between the first terminal of the first switch unit QN6 and the corresponding voltage divider circuit, and the second terminal of the fourth resistor R4 is connected to the control terminal of the second switch unit QN5. The start-up slow start module may include a second capacitor C2 and a fifth resistor R5. The first terminal of the second capacitor C2 is connected to the first terminal of the first capacitor C1, the second terminal of the second capacitor C2 is connected to the control terminal of the third switch unit QN4. One terminal of the fifth resistor R5 is connected between the first terminal of the second switch transistor and the corresponding voltage divider circuit, and the other terminal of the fifth resistor R5 is connected to the control terminal of the third switch transistor. The shutdown discharge module may include a diode D1. The anode of the diode D1 is connected between the first terminal of the second switch transistor and the corresponding voltage divider circuit, and the cathode of the diode D1 is connected to the control terminal of the third switch transistor. It should be understood that in other exemplary embodiments of the present disclosure, the switch module may also have other structures.
On this basis, the output of respective voltage output terminals can be correspondingly controlled by setting multiple switch modules. For example, the present disclosure may include a first switch module, a second switch module, and a third switch module. The first switch module, the second switch module, and the third switch module may be located on the same circuit board as the first signal transmission module 12. As shown in
In an exemplary embodiment, in a case where the third power supply signal V3 and the fourth power supply signal V4 output by the signal source end are configured to power the display unit and the photoelectric converter of the display end, the first connector may include one or more first pins to fourth pins, depending on the number of power lines to be connected. For example, the first connector may include two first pins, two third pins, two fourth pins and one second pin. The third connector connected to the first connector may include two thirty-first pins, one thirty-second pin, two thirty-third pins and two thirty-fourth pins. The first pin is connected to the thirty-first pin, and the thirty-first pin is connected to the first power line in the transmission part 3 for transmitting the first power supply signal V1. The third pin is connected to the thirty-third pin. The thirty-third pin is connected to the third power line in the transmission part 3, and is configured to transmit the third power supply signal V3. The fourth pin is connected to the thirty-fourth pin. The thirty-fourth pin is connected to the fourth power line in the transmission part 3, and is configured to transmit the fourth power supply signal V4. The second pin is connected to the third-second pin. The thirty-second pin is connected to the second power line in the transmission part 3, and is configured to transmit the detection level signal VCAB_DET.
In addition, it should be understood that, based on the same principle, the display device can also implement a hot plug detection function on the display end. The second connector of the display end is connected to the fourth connector of the transmission part 3. The second connector may include a twenty-first pin, a twenty-second pin, a twenty-third pin, and a twenty-fourth pin. The fourth connector may include a forty-first pin, a forty-second pin, a forty-third pin, and a forty-fourth pin. The forty-first pin is connected to the twenty-first pin, the forty-second pin is connected to the twenty-second pin, the forty-third pin is connected to the twenty-third pin, and the forty-fourth pin is connected to the twenty-fourth pin. The pin lengths of the forty-first pin, the forty-second pin, the forty-third pin, and the forty-fourth pin in the fourth connector may be set to be the same, and the pin length of the twenty-third pin in the second connector is set to be the same as the pin length of the twenty-fourth pin, and the pin lengths of the twenty-first pin, the twenty-third pin, and the twenty-second pin are set to decrease in sequence. Or, the pin lengths of the twenty-first pin, the twenty-second pin, the twenty-third pin, and the twenty-fourth pin in the second connector are set to be the same, the pin length of the forty-third pin in the fourth connector is set to be the same as the pin length of the forty-fourth pin, and the pin lengths of the forty-first pin, the forty-third pin, and the forty-second pin are set to decrease in sequence, thereby realizing the hot plug detection function of the display device on the display end. The principle of hot plug detection is the same as the hot plug detection principle at the signal source end mentioned above, and will not be repeated here.
It should be understood that, for the display device, the first connector and the third connector, the second connector and the fourth connector can simultaneously have the hot-plug function of the power interface, so that no matter whether the signal source end or the display end is connected or separated first, the display device can realize the hot-plug detection function. Of course, in other exemplary embodiments of the present disclosure, the hot-plug function of the power interface can also be provided only at the signal source end, or only at the display end, and these all belong to the protection scope of the present disclosure.
In an exemplary embodiment, the first control circuit 11 can also include a first power control terminal, a second power control terminal and a third power control terminal. The first control circuit 11 can output a first power control signal GPIO1 through the first power control terminal, and control the output state of the first voltage output terminal Vo1 based on the above-mentioned switch module; output a second power control signal GPIO2 through the second power control terminal to control the output state of the third voltage output terminal; and output a third power control signal GPIO3 through the third power control terminal to control the output state of the fourth voltage output terminal. The first power control terminal, the second power control terminal and the third power control terminal can be general input and output ports GPIO, and the first control circuit outputs corresponding power control signals through different general input and output ports GPIO. The control principles of the output states of respective voltage output terminals by the first control circuit 11 are similar. The following is only an example of the first control circuit 11 controlling the output state of the third voltage output terminal through the second power control terminal.
As shown in
As shown in Table 3, when the second power control signal GPIO2 output by the first control circuit 11 is at a high level, the control terminal of the second switch unit QN5 in the second switch module is at a high level, and the second switch unit QN5 is turned off, so that the control terminal of the third switch unit QN4 is at a high level, and the third switch unit QN4 is turned off, thereby controlling the third voltage output terminal to stop outputting the third power supply signal V3. When the second power control signal GPIO2 output by the first control circuit 11 is at a low level, the control terminal of the second switch unit QN5 in the second switch module is at a low level, and the second switch unit QN5 is turned on, so that the control terminal of the third switch unit QN4 is at a low level, and the third switch unit QN4 is turned on, thereby controlling the third voltage output terminal to output the third power supply signal V3. As shown in
The first signal transmission module 12 of the display end 2 of the present disclosure may include multiple photoelectric converters, and the specific number of photoelectric converters may be determined according to the resolution of the display device.

That is, one optoelectronic unit can transmit 8 pairs of optical signals. It should be understood that in other exemplary embodiments of the present disclosure, one optoelectronic unit can also transmit other numbers of pairs of optical signals.
In the exemplary embodiment, the power of the first optoelectronic unit and the power of the third optoelectronic unit may be greater than the power of the second optoelectronic unit, and the power of the fourth optoelectronic unit and the power of the sixth optoelectronic unit may be greater than the power of the fifth optoelectronic unit. That is, a high-power optoelectronic unit is configured to transmit a high-speed signal, and a low-power optoelectronic unit is configured to transmit a low-speed signal.
The structure of the display end 2 of the present disclosure is further described below in conjunction with the accompanying drawings. As shown in
As shown in
Alternatively, when the signal source end outputs the first power supply signal V1 to the display end to power the backlight unit of the display end and outputs the third power supply signal V3 to power the display unit, the second connector may include not only the 21st pin and the 22nd pin but also the 23rd pin and the 24th pin, and the number of pins may be determined according to the number of connected power lines. For example, two 23rd pins and two 24th pins may be included, and the fourth connector may also include the 43rd pin and the 44th pin. The 41st pin is connected to the 21st pin, the 42nd pin is connected to the 22nd pin, the 43rd pin is connected to the 23rd pin, and the 23rd pin may be connected to the third pin in the first connector via the power line in the transmission part 3. The 44th pin is connected to the 24th pin, and the 24th pin may be connected to the fourth pin in the first connector via the power line in the transmission part 3. The pin lengths of the 41st, 42nd, 43rd and 44th pins in the fourth connector can be set to be the same, the pin length of the 23rd pin in the second connector can be set to be the same as the pin length of the 24th pin, and the pin lengths of the 21st, 23rd and 22nd pins can be set to decrease in sequence. Or, the pin lengths of the 21st, 22nd, 23rd and 24th pins in the second connector can be set to be the same, the pin length of the 43rd pin in the fourth connector can be set to be the same as the pin length of the 44th pin, and the pin lengths of the 41st, 43rd and 42nd pins can be set to decrease in sequence. In this way, the first control circuit can also realize the hot plug detection function on the display end 2 based on the detection level signal VCAB_DET.
In an exemplary embodiment of the present disclosure, for example, for a UHD 60 Hz TV panel, the second connector may further include the aforementioned 23rd to 26th pins. The third power supply signal V3 is transmitted through the 23rd pin. The fourth power supply signal V4 is transmitted through the 24th pin. The optical signal corresponding to the first sub-data signal VB1 is transmitted by connecting the 25th pin to the optical fiber in the transmission part 3. The first display control signal D1 is transmitted by connecting the 26th pin to the optical fiber in the transmission part 3.
As shown in
In an exemplary embodiment of the present disclosure, for example, for a UHD 60 Hz TV panel, the display end 2 may include two photoelectric converters, which are a fourth photoelectric unit 211 and a fifth photoelectric unit 212. The fourth photoelectric unit 211 communicates with the first photoelectric unit 121 of the signal source end 1 to transmit a high-speed signal for converting an optical signal corresponding to the first sub-data signal VB1 into the first sub-data signal VB1. The fifth photoelectric unit 212 communicates with the second photoelectric unit of the signal source end 1 to transmit a low-speed signal for converting the first display control signal D1 into an optical signal for transmission and converting the optical signal corresponding to the first communication signal T1 and outputting it.
In another exemplary embodiment of the present disclosure, for example, for a UHD 120 Hz TV panel, the display end 2 may include a fourth photoelectric unit 211, a fifth photoelectric unit 212, and a sixth photoelectric unit 213. The fourth photoelectric unit 211 communicates with the first photoelectric unit 121 of the signal source end 1, transmits the first 8 pairs of high-speed signals, and is configured to convert the optical signal corresponding to the first sub-data signal VB1 into the first sub-data signal VB1. The fifth photoelectric unit 212 communicates with the second photoelectric unit of the signal source end 1, and transmits the low-speed signal. The fifth photoelectric unit 212 includes a first channel and a second channel. The first channel is configured to convert the first display control signal D1 into an optical signal for transmission, and the second channel is configured to convert the optical signals corresponding to the second display control signal D2 and the first communication signal T1 into the second display control signal D2 and the first communication signal T1 and output them to the second control circuit 22. The sixth photoelectric unit 213 is configured to convert the optical signal corresponding to the second sub-data signal VB2 into the second sub-data signal VB2.
In addition, as shown in
The step-down unit 24 of the display end 2 may also have a structure as shown in
In addition, in an exemplary embodiment, the second control circuit 22 can be configured to output the first display control signal D1 when obtaining the third power supply signal V3. The second signal transmission module 21 converts the first display control signal D1 into an optical signal for transmission. The first signal transmission module 12 converts the optical signal into the first display control signal D1 and outputs it to the first control circuit 11 to instruct the first control circuit 11 to output the V BY ONE data signal. In other words, after the second control circuit 22 located at the display end 2 obtains the third power supply signal V3, it indicates that the first signal transmission module 12 of the signal source end 1 and the second signal transmission module 21 of the display end 2 have established a connection, and the second control circuit 22 outputs the first display control signal D1 to the first control circuit 11 to instruct the first control circuit 11 to output the V BY ONE data signal.
In an exemplary embodiment, the optical fiber in the transmission part 3 can include a plurality of sub-optical fibers, and the number of sub-optical fibers can correspond to the number of photoelectric converters of the signal source end 1 and the display end 2.
As shown in
As shown in
On this basis, in an exemplary embodiment, the transmission part 3 may include a third connector and a fourth connector. The third connector is configured to connect to the first connector of the signal source end, and the fourth connector is configured to connect to the second connector of the display end. The third connector and the fourth connector may have the same structure and pin features, so the third connector may also be connected to the second connector, and the fourth connector may also be connected to the first connector. These all belong to the protection scope of the present disclosure. The present disclosure is only exemplified by the third connector being connected to the first connector and the fourth connector being connected to the second connector.
In an exemplary embodiment, in a case where the signal source end only outputs the first power supply signal V1 to the display end to power the backlight unit of the display end, the third connector may include a thirty-first pin and a thirty-second pin, and the fourth connector may include a forty-first pin and a forty-second pin. The thirty-first pin is configured to connect the first pin, the thirty-second pin is configured to connect the forty-second pin, the forty-first pin is configured to connect the twenty-first pin, and the forty-second pin is configured to connect the twenty-second pin. The first pin, the twenty-first pin, the thirty-first pin, and the forty-first pin are configured to transmit the first power supply signal V1, and the second pin, the twenty-second pin, the thirty-second pin, and the forty-second pin are configured to transmit the detection level signal VCAB_DET. In order to realize the hot plug detection function, the pin length of the thirty-first pin and the pin length of the thirty-second pin can be set to be different. For example, the pin lengths of the first pin and the second pin in the first connector can be set to be the same, the pin length of the thirty-first pin in the third connector can be set to be greater than the pin length of the thirty-second pin, and the pin length of the twenty-first pin in the second connector can be set to be the same as the pin length of the twenty-second pin, and the pin length of the forty-first pin in the fourth connector can be set to be greater than the pin length of the forty-second pin. Thus, during the process of the third connector being inserted into the first connector or the fourth connector being inserted into the second connector, the pin for transmitting the detection level signal VCAB_DET in the transmission part 3 contacts the first connector or the second connector later than the pin for transmitting the first power supply signal V1, and during the process of the third connector being unplugged from the first connector or the fourth connector being unplugged from the second connector, the pin for transmitting the detection level signal VCAB_DET in the transmission part 3 separates from the first connector or the second connector earlier than the pin for transmitting the first power supply signal V1, so that the first control circuit can realize the hot plug detection function based on the detection level signal VCAB_DET. In addition, the third connector may further include the 33rd to 36th pins, and the fourth connector may further include the 43rd to 46th pins. The 33rd to 36th pins are connected to the 3rd to 6th pins in the first connector, and the 43rd to 46th pins are connected to the 23rd to 26th pins in the second connector. The transmission part of this structure can be applied to UHD 60 Hz TV panels.
In an exemplary embodiment, when the signal source end outputs the first power supply signal V1, the third power supply signal V3 and the fourth power supply signal V4 to the display end, the third connector may include the 31st to 34th pins, and the fourth connector may include the 41st to 44th pins. The 31st pin is configured to connect the first pin in the first connector, the 32nd pin is configured to connect the second pin in the first connector, the 33rd pin is configured to connect the third pin in the first connector, and the 34th pin is configured to connect the fourth pin in the first connector; the 41st pin is configured to connect the 21st pin in the second connector, the 42nd pin is configured to connect the 22nd pin in the second connector, the 43rd pin is configured to connect the 23rd pin in the second connector, and the 44th pin is configured to connect the 24th pin in the second connector. The 31st and 41st pins are configured to transmit the first power supply signal V1, the 32nd and 42nd pins are configured to transmit the detection level signal VCAB_DET, the 33rd and 43rd pins are configured to transmit the third power supply signal V3, and the 34th and 44th pins are configured to transmit the fourth power supply signal V4. Similarly, the pin lengths of the first pin, the second pin, the third pin, and the fourth pin in the first connector can be set to be the same, the pin length of the thirty-third pin in the third connector can be set to be the same as the pin length of the thirty-fourth pin, and the pin lengths of the thirty-first pin, the thirty-third pin, and the thirty-second pin decrease in sequence, and the pin lengths of the twenty-first pin, the twenty-second pin, the twenty-third pin, and the twenty-fourth pin in the second connector can be set to be the same, and the pin length of the forty-third pin in the fourth connector can be set to be the same as the pin length of the forty-fourth pin, and the pin lengths of the forty-first pin, the forty-third pin, and the forty-second pin decrease in sequence. In this way, when the pin lengths for transmitting power supply signals in the first connector and/or the second connector are the same, the first control circuit can also implement the hot plug detection function based on the detection level signal VCAB_DET.
On the basis of the above embodiment, the third connector may further include the 33rd to 36th pins, and the fourth connector may further include the 43rd to 46th pins. The 33rd to 36th pins are connected to the 3rd to 6th pins in the first connector, and the 43rd to 46th pins are connected to the 23rd to 26th pins in the second connector. The transmission part of this structure can be applied to UHD 60 Hz TV panels. Alternatively, the third connector may further include the 33rd to 38th pins, and the fourth connector may further include the 43rd to 48th pins, the 33rd to 38th pins are connected to the 3rd to 8th pins in the first connector, and the 43rd to 48th pins are connected to the 23rd to 28th pins in the second connector. The transmission part of this structure can be applied to UHD 120 Hz TV panels. The purpose, definition of each pin and number of pins can be found in the introduction of the above embodiment, and will not be described in detail here.
Compared with the traditional use of electronic cables to transmit low-speed signals, which requires more than a dozen electronic cables, and the loss will be very large when the cable length increases, the transmission part 3 of this exemplary embodiment uses optical fiber to transmit V BY ONE data signals. There will be no loss problem when transmitting through optical fiber, and as the cable length increases, the cost of optical fiber transmission will be more advantageous.
