Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit it. In the following description, when referring to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this application; they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of this application as detailed in the appended claims.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0020] Before providing a detailed description of the embodiments of this application, some of the nouns and terms involved in the embodiments of this application will be explained first. The nouns and terms involved in the embodiments of this application are subject to the following interpretations.

[0021] 1) LVDS (Low-Voltage Differential Signaling) is a differential signaling technology with low power consumption, low bit error rate, low crosstalk and low radiation. This transmission technology can reach speeds of 155Mbps and above. The core of LVDS technology is to use extremely low voltage swing to transmit data at high speed differentially, which can realize point-to-point or point-to-multipoint connections.

[0022] 2) eDP (Embedded DisplayPort) is an embedded display interface defined by VESA. It evolved from the DisplayPort protocol and uses serial differential transmission. The clock is embedded in the data stream, eliminating the need for a separate clock line. It typically uses 1-4 pairs of differential lines for transmission, and the single-channel rate can reach 1.62Gbps to 5.4Gbps and above. It supports 8b / 10b encoding and has the advantages of anti-interference, low power consumption, and standardization.

[0023] 3) VByOne (V-by-One HS) is a high-speed serial display interface developed by THine Electronics. It adopts serial differential transmission combined with CDR clock recovery and adaptive equalization technology. It has no independent clock line and the highest single-channel rate can reach 3.75Gbps. It can increase bandwidth through multi-channel aggregation. It has pre-emphasis and receiver equalization functions, which can effectively compensate for signal attenuation in long-distance transmission. It has low EMI interference and small clock offset problem.

[0024] Display systems typically use wired connections, which are prone to poor contact in complex environments due to vibration, corrosion, or frequent plugging and unplugging. The related technologies suffer from the following core limitations: Poor contact reliability: In industrial control, military, and marine scenarios, equipment is often exposed to high-frequency vibration, alternating high and low temperatures, and humid and corrosive environments. The metal contacts of wired interfaces are prone to wear and oxidation. Frequent plugging and unplugging can also cause the interface to loosen, which in turn can lead to problems such as display signal interruption, screen distortion, and lag, seriously affecting the normal operation of the equipment. Wiring limitations: Wired cables cannot be laid in confined spaces (such as precision cavities inside equipment or folding joints of portable display devices), or the wiring process may damage the equipment's structural seal, allowing dust and moisture to enter and affecting the equipment's lifespan. Insufficient portability: Wired connections require additional cables and adapters, and dragging cables can easily damage the interfaces, which does not meet the lightweight and convenient requirements of portable extended display devices; Poor compatibility and flexibility: Significant differences in screen interfaces among various display devices necessitate the use of multiple dedicated adapter modules for wired connections. This not only increases equipment cost and portability but also poses the risk of incompatibility between the adapter modules and the display devices or signal sources. Furthermore, with wired connections, switching between display devices requires manually plugging and unplugging adapter cables or replacing adapter modules, which is cumbersome, time-consuming, and hinders rapid switching, making it difficult to meet the flexible display needs of multiple monitors.

[0025] In view of this, this application provides a wireless display signal transmission system and method. The wireless display signal transmission system can convert initial display signals from multiple different interfaces into first video signals from multiple different protocols without the need for additional adapter modules. It is compatible with different types of display devices and signal sources, meets the needs of multi-monitor networking and portable extended display, and facilitates the expansion of display devices through magnetic or snap-fit ​​spacing structure components.

[0026] Figure 1 This is an optional structural flowchart of the wireless transmission system for display signals provided in the embodiments of this application. The system includes a signal transmitting module and a signal receiving module, which are connected by magnetic or snap-fit ​​spacer components. The signal transmitting module is used to respond to initial display signals from multiple different interfaces, converting the display signals into first video signals of multiple different protocols respectively; and performing radio frequency modulation on the first video signals to obtain wireless signals; The signal receiving module is used to respond to the wireless signal, restore the wireless signal to the first video signal, and display the first video signal on the display screen.

[0027] Specifically, the signal transmitting module and the signal receiving module are connected by magnetic or snap-fit ​​spacers, facilitating the expansion of the display. The signal transmitting module and the signal receiving module transmit data wirelessly, avoiding poor contact of wired interfaces in complex environments (vibration or corrosion), which could lead to signal interruption or display abnormalities. This improves the connection efficiency between portable devices. Through multi-protocol compatibility, the initial display signals from multiple different interfaces are converted into first video signals from multiple different protocols without the need for additional adapter modules. This adapts to different types of display devices and signal sources, meeting the needs of multi-monitor networking and portable extended display.

[0028] In some embodiments, the first video signal includes an eDP signal, the signal transmitting module includes an eDP transmitting module, the signal receiving module includes an eDP receiving module, and the eDP transmitting module and the eDP receiving module are connected through a first wireless channel and a second wireless channel. The first wireless channel is used for handshake protocol communication; The second wireless channel is used to transmit the wireless signal corresponding to the eDP signal after the handshake protocol communication.

[0029] Specifically, please refer to Figure 2 The first wireless channel is a Low-Speed ​​Control Channel, and the second wireless channel is a 60GHz Wireless Link (high-speed data channel). The left side of both channels houses the signal transmitting module, and the right side houses the signal receiving module. eDP signals are transmitted via the 60GHz link to achieve high bandwidth and low latency, while control signals such as AUX / HPD are transmitted via the low-speed channel to improve the integrity of the handshake protocol communication and the utilization of transmission resources.

[0030] In some embodiments, the eDP transmission module includes an AUX unit and an eDP transmission unit; The AUX unit is used to acquire a first control signal through a first wireless channel; The eDP transmission unit is used to convert the eDP signal into a wireless signal according to the first control signal.

[0031] Specifically, please refer to Figure 2 The eDP Source is the signal source, such as a laptop motherboard, industrial control host, or graphics card, which outputs the eDP signal. AUX (Auxiliary) is an auxiliary channel, a crucial low-speed data channel within the DisplayPort protocol stack used for control and management. HPD (Hot Plug Detect) is a hot-plug detection signal used to detect whether the display panel is connected. eDP Lanes 0-N are high-speed differential data channels that transmit video pixel data (eDP signal). The FPGA and MCU perform protocol parsing, data processing, control, status management, and bridging of the low-speed channel (UART). Low-speed control signals such as AUX / HPD are converted into serial data (UART) and transmitted through the low-speed wireless channel. The TX Lane is the eDP transmission unit, which radio frequency modulates the eDP signal into a wireless signal.

[0032] The RX Lane (60GHz receiver module) receives 60GHz wireless signals, demodulates and restores high-speed eDP data (Lane 0~N), the FPGA restores the wireless signals to eDP signals, and the Panel is a display panel that receives the restored eDP signals for video display.

[0033] In some embodiments, the signal transmitting module includes an eDP transmitting module, which includes an AUX unit and a data processing unit, with the AUX unit connected to the data processing unit. The data processing unit is used for the extended display identification data and display port configuration data fed back by the analog signal receiving module; The AUX unit is used to send eDP signals to the data processing unit in response to extended display identification data and display port configuration data, so as to convert the eDP signals into wireless signals and send them to the signal receiving module.

[0034] Specifically, please refer to Figure 3 The main uses of AUX are: 1. Reading EDID, 2. Link Training, 3. DPCD register configuration, 4. Backlight control (PWM / register), and 5. Panel status readback. AUX has the following problems: 1. Bidirectionality, 2. Dependency required, 3. The main control SoC considers it a "cable-level connection." Dependency: After power-on, the eDP interface must undergo link training through the AUX channel to negotiate transmission rate, number of channels, and equalization parameters. Without communication via the AUX channel, the display panel cannot establish a valid connection with the source (such as the graphics card or SoC), resulting in no display output. Cable-level connection: Because the connection process has speed requirements, wireless latency can cause handshake failures, requiring a speed similar to that of a hardware cable connection.

[0035] Therefore, in this embodiment, the transmitting end (signal transmission module) uses FBGA to simulate the screen's protocol, making the transmitting end believe it is connected to a real eDP screen. The AUX signal is then tricked into revealing the SOC / GPU's video data at the transmitting end. The receiving end (signal receiving module), acting as the "real screen," generates its own AUX response.

[0036] Furthermore, the MCU and FPGA (data processing unit) of the signal transmission module locally simulate EDID (Extended Display Identification Data) and DPCD (Display Port Configuration Data). The transmitter and receiver signals are converted into a unified format, a virtual EDID is saved, and the DPCD parameters (Lane / Rate) are fixed. Then, AUX requests are responded to locally, and the video image signal is transmitted via the ST60A2 as the TX signal. The receiver can receive the AUX protocol and uses the ST60A2 as the RX signal to receive the video image signal.

[0037] This embodiment enables the wireless link to be completely transparent to AUX without requiring modifications to the SoC / GPU, with AUX only responding at the transmitting end, reducing control latency and configuration failures caused by wireless interference.

[0038] In some embodiments, the first video signal includes an LVDS signal, and the signal transmitting module further includes an LVDS transmitting module, which includes an LVDS data processing module; The LVDS data processing module is used to perform radio frequency modulation on the LVDS signal according to the LVDS clock to obtain the corresponding wireless signal.

[0039] Specifically, please refer to Figure 4 The LVDS Source is the signal source, such as an industrial control motherboard or display driver board, which outputs LVDS signals, including an LVDS clock for synchronizing data transmission and LVDS data for transmitting video pixel data. The LVDS data processing module is the LVDS data TX. The LVDS data Rx module at the receiving end receives the 60GHz wireless signal, demodulates and restores the high-speed data, converts the data back into the standard LVDS signal format, and outputs the restored LVDS clock and data signals. The panel receives the restored LVDS signal, thus completing the wireless transmission of the LVDS signal.

[0040] In some embodiments, the first video signal includes a VByOne signal, and the signal transmitting module further includes a VByOne transmitting module, which includes a VByOne data processing unit and a VByOne transmission unit. The VByOne data processing unit is used to perform link training with the signal receiving module based on I2C signals, hot-plug detection signals, and phase-locked loop locking signals to build the third and fourth wireless channels. The VByOne data processing unit is also used to transmit a second control signal via a third wireless channel; The VByOne transmission unit is used to transmit VByOne signals through the fourth wireless channel according to the second control signal.

[0041] Specifically, please refer to Figure 5 Similar to the eDP transmitter module, the VByOne transmitter module includes a Vby-one Source (for Vby-one signal sources such as TV motherboards, industrial control driver boards, and video processing hosts), a Vby-one Data (for high-speed serial differential video streams), and an embedded clock design. LOCK is a phase-locked loop (PLL) lock signal used to indicate whether the link is correctly synchronized with the embedded clock; it is a core indicator of stable V-by-One link operation. HTPD is a hot-plug detection signal, functionally equivalent to the HPD in eDP. IIC is an I2C bidirectional control bus used for reading and writing panel EDID parameters, configuring driver chip registers, and adjusting brightness / contrast, etc.

[0042] The FPGA and MCU unit (i.e., the VByOne data processing unit) receives the V-by-One high-speed data signal, performs protocol parsing, deserialization, and data repackaging, converting it into a transmission format adapted for radio frequency. Simultaneously, it acquires low-speed LOCK, HTPD, and IIC signals, performing level conversion and timing synchronization, monitoring link status, and handling exceptions and reconnection logic. The TX Lanes 0~N 60GHz (VByOne transmission unit) modulate the high-speed video data output from the FPGA onto a 60GHz carrier wave and transmit it via antenna, achieving low latency and high bandwidth.

[0043] In some embodiments, the initial display signal includes an HDMI signal, a DP signal, and a Type-C signal. The signal transmission module also includes a signal conversion module, which is connected to the eDP transmission module, the LVDS transmission module, and the VByOne transmission module, respectively. The signal conversion module is used to convert HDMI, DP, or Type-C signals into eDP, LVDS, or VByOne signals in response to HDMI, DP, or Type-C signals.

[0044] Specifically, please refer to Figure 6 The signal conversion module can be a display chip that receives video signals from different protocols such as Type-C, HDMI, and DP (eDP). It first converts the video signals of different input protocols into a standardized intermediate video data format, and then encodes them into three screen-specific signal protocols, namely eDP, LVDS, and VByOne, according to the type of the back-end display panel, so as to achieve flexible adaptation and improve the front-end's ability to support multiple input protocols.

[0045] In some embodiments, the power supply method can be contact, pogo pin connection, or magnetic wireless power supply.

[0046] In some embodiments, please refer to Figure 7This is a wireless signal transmission system for displays, compatible with mainstream video input interfaces such as Type-C, HDMI, and DP. It adapts to various signal sources, including laptops, PCs, industrial control systems, and military terminals. The system decodes and converts multi-protocol video signals via the monitor's motherboard, generating three independent dedicated display signals for the screen: eDP, LVDS, and V-by-One. These signals are then modulated and transmitted wirelessly over a short distance via a corresponding 60GHz to 61GHz millimeter-wave wireless transmission module. The receiving end, through a matching dedicated wireless receiving module, demodulates the signal, restores the native protocol and timing, and directly drives the corresponding interface display panel. This achieves fully transparent wireless bridging between the signal source and the display panel without requiring modifications to existing hardware and drivers, effectively solving the problems of poor contact, limited cabling, poor compatibility with multiple interfaces, and inflexible networking inherent in traditional wired display transmission.

[0047] In some embodiments, please refer to Figure 8 A wireless signal transmission terminal has multiple magnetic power pogopin units 110 and antennas 130 evenly arranged around the frame, which, together with the radio frequency receiving module unit 120 in the middle, achieves precise magnetic alignment with the terminal, wireless power supply and millimeter-wave high-speed video signal transmission. It eliminates physical interfaces and cables, and improves the structural sealing and portability of the device while achieving stable transmission of display signals.

[0048] This application also provides a method for wireless transmission of display signals. Figure 1 The method may include, but is not limited to, steps S101 to S102.

[0049] Step S101: In response to the initial display signals from multiple different interfaces, the display signals are converted into first video signals of multiple different protocols respectively; Step S102: The first video signal is radio frequency modulated to obtain a wireless signal, which is then transmitted to the signal receiving module. The signal receiving module then restores the wireless signal to the first video signal and displays the first video signal on the display screen.
