[0003] However, the audio in this way is the analog audio left and right channels, which does not support digital audio. Moreover, the display interfaces are DVI-D / TMDSt and DisplayPort, and the EDP display function cannot be realized, making it difficult to meet the usage requirements. Summary of the Utility Model

[0004] The purpose of this application is to provide a display system and device based on HDMI and EDP to solve the problems that it is difficult to meet the requirements of not supporting digital audio and realizing the EDP display based on the existing Open Pluggable Specification.

[0005] To solve the above problems, the following technical solutions are adopted in this application for implementation:

The power supply unit is connected to the TX24 module. The HDMI module is used for HDM signal transmission. The EDP module is used for EDP and DP displays. The IIS audio module is used to separate audio data and clock signals and perform independent wire transmission of the clock and audio data signals. The TX25 connector is respectively connected to the IIS audio module, the TX24 module, the EDP module, and the HDMI module to control the separate displays of the IIS audio module, the EDP module, and the HDMI module.

[0007] Compared with the prior art that only supports the analog audio left and right channels, this application supports high-quality digital audio transmission by integrating the IIS audio module, providing a clearer and richer audio experience. By adopting the HDMI and EDP modules, the display system has a higher resolution and wider color gamut support, meeting more stringent display requirements.

[0008] Further, the TX25 connector includes a first chip and a first impedance circuit. The first chip is respectively connected to the IIS audio module, the TX24 module, the EDP module, the HDMI module, and is connected to the first impedance circuit. The other end of the first impedance circuit is connected to the OPS line.

[0009] By integrating the first chip and the first impedance circuit in the TX25 connector, high-quality connection of the IIS audio module can be achieved. Adding the first impedance circuit in the connector enables the OPS line to support the digital display interface, meeting the requirements of higher resolution and large-screen display.

[0010] Further, the TX25 connector includes a grounding resistor. One end of the grounding resistor is grounded, and the other end is connected to the first chip. The grounding resistor is used to monitor the plugging and unplugging state of the TX25 connector.

[0011] Integrating the grounding resistor in the TX25 connector can effectively reduce the damage to the connector and electronic devices caused by static electricity generated during plugging and unplugging operations. The grounding resistor is used to monitor the plugging and unplugging state of the TX25 connector, and can detect whether the connector is correctly plugged and unplugged in real time, as well as the change in the connection state during the plugging and unplugging process, thereby improving the stability and reliability of the system.

[0012] Further, the display system based on HDMI and EDP includes two groups of ESD protectors. One group of ESD protectors is respectively connected to the first chip and the EDP module, and the other group of ESD protectors is respectively connected to the first chip and the HDMI module.

[0013] By integrating two groups of ESD protectors in the display system based on HDMI and EDP, hardware damage caused by electrostatic discharge events can be effectively prevented, ensuring the stable operation of the display system.

[0014] Further, the TX25 connector includes two groups of inductive reactance circuits. One group of inductive reactance circuits is respectively connected to the first chip and the EDP module, and the other group of inductive reactance circuits is respectively connected to the first chip and the HDMI module.

[0015] Integrating two groups of inductive reactance circuits in the TX25 connector can effectively suppress electromagnetic interference, ensure the purity and stability of the signal, thereby improving the signal quality between the first chip and the EDP module and the HDMI module, and reducing data transmission errors.

[0016] Further, the TX25 connector includes a capacitive reactance circuit. One end of the capacitive reactance circuit is grounded, and the other end is connected to the first chip.

[0017] The TX25 connector integrates a capacitive reactance circuit, which can filter high-frequency noise in the transmission line, thereby improving the signal integrity of the first chip, reducing data transmission errors, and ensuring stability.

[0018] Further, the EDP module includes a filtering circuit and an EDP unit, and the filtering circuit is respectively connected to the EDP unit and the TX25 connector.

[0019] The filtering circuit integrated in the EDP module can filter the signals between the EDP unit and the TX25 connector, effectively reducing the noise and interference in the signal transmission process, thereby improving the signal quality.

[0020] Further, the EDP module includes a field-effect transistor and an electrostatic protector. The field-effect transistor, the electrostatic protector, and the EDP unit are connected in sequence, and one end of the field-effect transistor is connected to the power input.

[0021] Adopting a field-effect transistor to connect the power input in the EDP module can effectively manage and regulate the power input, improve the efficiency and stability of power management. The integration of the electrostatic protector can provide an additional protection layer to prevent electrostatic damage to sensitive EDP units and other electronic components.

[0022] Further, the number of the electrostatic protectors is multiple, and the multiple electrostatic protectors are arranged in parallel.

[0023] By arranging multiple electrostatic protectors in parallel, the electrostatic protection ability of the whole system can be improved, ensuring that the system can be effectively protected when suffering from electrostatic impact. When multiple electrostatic protectors are arranged in parallel, in the case of the failure of a single protector, other protectors can still continue to provide protection, thereby improving the overall stability of the system.

The HDMI-based split-screen system includes: an I IS audio module 100, a TX25 connector 200, a TX24 module 300, a power supply unit 400, an EDP module 500, and an HDMI module 600. The power supply unit 400 is connected to the TX24 module 300. The HDMI module 600 is used for HDM signal transmission. The EDP module 500 is used for EDP and DP display. The I IS audio module 100 is used to separate audio data and clock signals and independently transmit the clock and audio data signals through wires. The TX25 connector 200 is respectively connected to the IIS audio module 100, the TX24 module 300, the EDP module 500, and the HDMI module 600 to control the separate displays of the IIS audio module 100, the EDP module 500, and the HDMI module 600.

[0038] Specifically, the TX25 connector 200 connecting the IIS audio module 100, TX24 module 300, EDP module 500, and HDMI module 600 should comply with the Open Pluggable Specification (OPS-C) to ensure compatibility with existing systems. Connect the power supply unit 400 to the TX24 module 300 to provide a stable power supply for the modules and ensure the normal operation of the system. The HDMI module 600 is used to transmit HDMI signals and achieve high-definition video transmission through the HDMI interface to meet the requirements of high resolution and high refresh rate. Among them, the EDP module 500 is used to implement EDP and DP display functions and transmit high-definition video signals through the EDP interface to provide a better display effect. The IIS audio module 100 is used to separate audio data and clock signals and perform independent wire transmission to ensure the clarity and stability of audio signals. The TX25 connector 200 is respectively connected to the IIS audio module 100, TX24 module 300, EDP module 500, and HDMI module 600 to control the signal transmission and display between the modules. By controlling the IIS audio module 100, EDP module 500, and HDMI module 600, the viewing experience is improved.

[0039] It should be noted that the existing method only supports the analog audio left and right channels. This application supports high-quality digital audio transmission by integrating the IIS audio module 100, providing a clearer and richer audio experience. By adopting the HDMI module 600 and EDP module 500, the display system has a higher resolution and wider color gamut support, meeting more stringent display requirements.

[0040] In some embodiments, the TX25 connector 200 includes a first chip 210 and a first impedance circuit 220. The first chip 210 is respectively connected to the IIS audio module 100, TX24 module 300, EDP module 500, HDMI module 600, and the first impedance circuit 220. The other end of the first impedance circuit 220 is connected to the OPS line.

[0041] Specifically, connect the IIS audio module 100, TX24 module 300, EDP module 500, HDMI module 600, and TX25 connector 200 together to form a closed circuit system. The first chip 210 is responsible for processing and forwarding signals between the modules. The first impedance circuit 220 is used to match and adjust the impedance of the signals. Connect the other end of the first impedance circuit 220 to the OPS line to achieve compatibility with the Open Pluggable Specification (OPS-C). By controlling the IIS audio module 100, TX24 module 300, EDP module 500, and HDMI module 600 through the TX25 connector 200, under the control of the first chip 210, the signals between the modules are mutually matched and adjusted to ensure the stable operation of the entire system.

[0042] By integrating the first chip 210 and the first impedance circuit 220 in the TX25 connector 200, a high-quality connection of the IIS audio module 100 can be achieved. Adding the first impedance circuit 220 to the TX25 connector enables the OPS line to support the digital display interface, meeting the requirements of higher resolution and large-screen display.

[0043] In some embodiments, the TX25 connector 200 includes a ground resistor 230. One end of the ground resistor 230 is grounded, and the other end is connected to the first chip 210. The ground resistor 230 is used to monitor the plugging and unplugging state of the TX25 connector 200.

[0044] Specifically, connect one end of the ground resistor 230 to the ground wire to ensure that the potential between the entire system and the ground is the same, so as to reduce interference. Connect the other end of the ground resistor 230 to the first chip 210, enabling the first chip 210 to establish a connection with the ground through the ground resistor 230. The first chip 210 determines whether the TX25 connector 200 is plugged or unplugged by monitoring the connection state of the ground resistor 230. When the TX25 connector 200 is inserted, the ground resistor 230 will be connected to the ground. After the first chip 210 detects this change, it can trigger the corresponding plugging and unplugging event handler. When the TX25 connector 200 is unplugged, the connection between the ground resistor 230 and the ground is disconnected. The first chip 210 also detects this change and triggers the corresponding plugging and unplugging event handler, realizing real-time monitoring of the plugging and unplugging state of the TX25 connector 200 to ensure the stable operation of the system.

[0045] Integrating the ground resistor 230 in the TX25 connector 200 can effectively reduce the damage to the connector and electronic devices caused by static electricity generated during the plugging and unplugging operations. And by whether the ground resistor 230 is connected to the relevant component circuits, resulting in current / voltage changes, the plugging and unplugging state of the TX25 connector 200 can be obtained, thereby achieving the effect of monitoring the plugging and unplugging state of the TX25 connector 200, and improving the stability and reliability of the system.

[0046] In some embodiments, the display system based on HDMI and EDP includes two groups of ESD protectors 700. One group of ESD protectors 700 is respectively connected to the first chip 210 and the EDP module 500, and the other group of ESD protectors is respectively connected to the first chip 210 and the HDMI module 600.

[0047] Specifically, prepare two sets of ESD protectors 700 to prevent damage to system components caused by electrostatic discharge (ESD). Connect the first set of ESD protectors 700 between the first chip 210 and the EDP module 500. For example, this is achieved by connecting the input terminals of the ESD protectors to the data lines of the first chip 210 and the EDP module 500. Connect the second set of ESD protectors between the first chip 210 and the HDMI module 600. Similarly, this is achieved by connecting the input terminals of the ESD protectors to the data lines of the first chip 210 and the HDMI module 600. Ensure that the output terminals of the ESD protectors 700 are respectively connected to the corresponding data lines or signal lines to protect these lines from electrostatic discharge. During the normal operation of the system, the ESD protectors 700 will monitor the data lines or signal lines at the input terminals to prevent any electrostatic discharge event from damaging the first chip 210, the EDP module 500, and the HDMI module 600. If an electrostatic discharge event is detected, the ESD protectors 700 will take measures through their output terminals, such as absorbing or dispersing the electrostatic energy, to protect the connected components from damage.

[0048] By integrating two sets of ESD protectors 700 in the HDMI- and EDP-based display system, it is possible to effectively prevent hardware damage caused by electrostatic discharge events and ensure the stable operation of the display system.

[0049] In some embodiments, the TX25 connector 200 includes two sets of inductive reactance circuits 240. One set of inductive reactance circuits 240 is respectively connected to the first chip 210 and the EDP module 500, and the other set of inductive reactance circuits 240 is respectively connected to the first chip 210 and the HDMI module 600.

[0050] Specifically, connect the first set of inductive reactance circuits 240 between the first chip 210 and the EDP module 500. For example, this is achieved by connecting the input terminals of the inductive reactance circuits 240 to the data lines of the first chip 210 and the EDP module 500. Connect the second set of inductive reactance circuits 240 between the first chip 210 and the HDMI module 600. Similarly, this is achieved by connecting the input terminals of the inductive reactance circuits 240 to the data lines of the first chip 210 and the HDMI module 600.

[0051] During the normal operation of the system, the inductive reactance circuits 240 will monitor the data lines or signal lines at the input terminals to prevent any inductive reactance circuit from interfering with the first chip 210, the EDP module 500, and the HDMI module 600. If interference from the inductive reactance circuit is detected, the inductive reactance circuits 240 will take measures through their output terminals, such as eliminating or reducing the impact of the inductive reactance circuit on the connected components.

[0052] Integrating two sets of inductive reactance circuits 240 in the TX25 connector 200 can effectively suppress electromagnetic interference, ensure the purity and stability of signals, thereby improving the signal quality between the first chip 210 and the EDP module 500 and the HDMI module 600, and reducing data transmission errors.

[0053] In some embodiments, the TX25 connector 200 includes a capacitive reactance circuit 250. One end of the capacitive reactance circuit 250 is grounded, and the other end of the capacitive reactance circuit 250 is connected to the first chip 210.

[0054] Specifically, grounding one end of the capacitive reactance circuit 250 ensures that the potential between the entire system and the ground is the same to reduce interference. Connecting the other end of the capacitive reactance circuit 250 to the first chip 210 enables the first chip 210 to establish a connection with the ground through the capacitive reactance circuit 250. During normal operation, the capacitive reactance circuit 250 will monitor the data lines or signal lines at the input end to prevent any capacitive interference from affecting the first chip 210. If capacitive interference is detected, the capacitive reactance circuit 250 will take measures through its output end, such as eliminating or reducing the impact of capacitive interference on the connected components.

[0055] Integrating the capacitive reactance circuit 250 in the TX25 connector 200, the capacitive reactance circuit 250 can filter high-frequency noise in the transmission line, thereby improving the signal integrity of the first chip 210, reducing data transmission errors, and ensuring stability.

[0056] In some embodiments, the EDP module 500 includes a filter circuit 510 and an EDP unit 520. The filter circuit 510 is respectively connected to the EDP unit 520 and the TX25 connector 200.

[0057] Specifically, connecting the filter circuit 510 to the EDP unit 520 and the TX25 connector 200 respectively is achieved by connecting the input end of the filter circuit 510 to the data line of the EDP unit 520 and connecting the output end of the filter circuit 510 to the data line of the TX25 connector 200, ensuring a good electrical connection between the output end of the filter circuit 510 and the data line of the TX25 connector 200 to ensure stable signal transmission. If interference is detected, the filter circuit 510 will take measures through its output end, such as eliminating or reducing the impact of interference on the connected components.

[0058] The filter circuit 510 integrated in the EDP module 500 can filter the signals between the EDP unit 520 and the TX25 connector 200, effectively reducing noise and interference during signal transmission, thereby improving signal quality.

[0059] In some embodiments, the EDP module 500 includes a field effect transistor 530 and an electrostatic protector 540. The field effect transistor 530, the electrostatic protector 540, and the EDP unit 520 are connected in sequence, and one end of the field effect transistor 530 is connected to the power input.

[0060] Specifically, the field effect transistor 530, the electrostatic protector 540, and the EDP unit 520 are connected in sequence. For example, first connect one end of the field effect transistor 530 to the power input to ensure that the EDP module 500 can obtain the required electrical energy from the power supply. Then, connect the other end of the field effect transistor 530 to the electrostatic protector 540, and finally connect the electrostatic protector 540 to the EDP unit 520. Among them, ensure that the connections between the field effect transistor 530, the electrostatic protector 540, and the EDP unit 520 are stable and reliable to ensure the stable transmission of electrical energy and signals. During operation, the field effect transistor 530 will act as a switch to control the flow of current. The electrostatic protector 540 will monitor the data line or signal line at the input end to prevent any electrostatic discharge (ESD) from damaging the EDP unit 520. If an electrostatic discharge event is detected, the electrostatic protector 540 will take measures through its output end, such as absorbing or dispersing electrostatic energy, to protect the connected components from damage.

[0061] It should be noted that during design, the rated voltage, current, and response time of the field effect transistor 530 and the electrostatic protector 540 should be considered to ensure that they can adapt to the specific requirements of the system. In particular, the number of electrostatic protectors 540 is multiple, and multiple electrostatic protectors 540 are connected in parallel. By connecting multiple electrostatic protectors 540 in parallel, the electrostatic protection ability of the entire system can be improved, ensuring that the system can be effectively protected when suffering from electrostatic shocks. Multiple electrostatic protectors 540 are connected in parallel to improve the overall stability of the system.

[0062] Adopting a field effect transistor 530 to connect the power input in the EDP module 500 can effectively manage and regulate the power input, improving the efficiency and stability of power management. The integration of the electrostatic protector 540 can provide an additional protection layer to prevent electrostatic damage to sensitive EDP units and other electronic components.

[0063] It should be noted that in order to meet the requirements of various display modes, the embodiments of the present application propose and implement a display implementation solution for 80PIN with HDMI and EDP / DP displays, and at the same time propose and implement an 80PIN OPS digital audio solution. Among them, the HDMI and EDP display solutions are used for the display mode, meeting the requirements of more display modes and usage scenarios. In terms of digital audio output, the IIS audio interface is adopted, which has been more and more widely used in audio circuit design. Compared with analog audio output, the IIS digital audio transmission adopts a design of transmitting clock and data signals along independent wires. By separating the data and clock signals, the distortion induced by time difference is avoided, further improving the audio quality. The IIS audio interface can provide better sound quality. Since the IIS audio interface adopts advanced digital audio processing technology, it can achieve higher sampling rates and wider dynamic ranges, thus providing richer and more delicate audio details and better sound quality performance.

[0064] To improve compatibility, the pluggable module is defined as NC or grounded pin, and the definition of the reserved pin. The pluggable computing module can change the BOM by soldering or not soldering the resistor on the main board to switch and adapt to the large screen. For the IIC signal of AMP initialization and EQ adjustment, in order to adapt to the previous Chinese Open Pluggable Specification (OPS-C), the pluggable computing module reserves the original definition of AZ_LINEOUT_R / AZLINEOUT_L. By slightly modifying the main board BOM and changing the position of the resistor, it is adapted to both the IIC signal for AMP initialization and EQ adjustment and AZ_LINEOUT_R / AZLINEOUT_L. For the MUTE signal of AMP, Low represents Mute and the power amplifier output is muted, and High represents Enable and the sound is output normally. IIS_MCLK can be a reserved function. By soldering or not soldering the 0-ohm resistor on the main board, it is adapted to the APM with and without MCLK signals, enhancing compatibility. Based on the 80Pin proposed for the interactive one-piece electronic whiteboard, an upgraded and innovative function is achieved on the basis of the original Open Pluggable Specification (OPS-C) definition, realizing high-quality digital audio output, improving the user experience, and at the same time achieving a display effect of 4K@60Hz, 24BPP on the large screen.

[0065] The present application also provides a display device based on HDMI and EDP. The display device based on HDMI and EDP includes the display system based on HDMI and EDP according to any one of the above.

[0066] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions required to be protected by the present application.
