[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] Example 1
[0029] Please see Figure 1 The present invention provides a technical solution: an LVDS port display screen self-adaptation system and adaptation method.
[0030] The problems addressed above include: the need to prepare different versions of circuit boards and cables for different display models during production, increasing material management and inventory costs; and the requirement for maintenance personnel to use displays identical to the original equipment for replacement, which could lead to display malfunctions or even complete failure if the models are incompatible, resulting in a lack of flexibility.
[0031] The solution is as follows: An LVDS port display screen self-adaptation system and adaptation method, comprising: a main processor, a signal switching logic circuit, a configuration information module, and an LVDS display screen. The configuration information module is used to store the configuration information of the LVDS display screen. The main processor is communicatively connected to the configuration information module and the signal switching logic circuit, and is used to read the configuration information after the system is powered on, and configure the signal switching logic circuit according to the configuration information.

The switching logic circuit is a configurable signal processing unit that can be implemented using a CPLD, FPGA, or dedicated signal switching chip. Based on configuration instructions provided by the main processor, it performs real-time conversion on the input standard LVDS signal, including data channel remapping, signal level adjustment, and timing fine-tuning, ensuring the output format fully meets the requirements of the target LVDS display. Upon power-up, the main processor does not immediately output a display signal; instead, it accesses and reads information from the configuration information module via a communication interface. If detailed parameters are read, they are used directly to configure the signal switching logic circuit. If a type code is read, the main processor queries its internal pre-stored configuration database to find the corresponding detailed parameters before configuration. This configuration system can adapt to numerous different LVDS display models, greatly improving the product's applicability and flexibility. In production, it reduces the types of circuit boards and simplifies material management and inventory. In maintenance, precise screen model matching is unnecessary, reducing spare parts costs and maintenance difficulty. The system automatically completes identification and configuration; users do not need to perform any manual settings. Through an external configuration module, a large number of existing traditional displays can also enjoy the convenience of adaptive functionality.
[0032] Furthermore, the configuration information module is integrated inside the LVDS display screen and connected to the main processor's communication interface via a display cable, which simplifies system wiring, improves system integration, reduces the number of external connection cables, and lowers the failure rate caused by loose or damaged connection cables.
[0033] In a further improvement, the configuration information module is an independent module external to the LVDS display screen, which is connected to the communication interface of the main processor through the configuration port. This improves the system's flexibility and allows the configuration information module to be upgraded or replaced separately without replacing the display screen, making maintenance and upgrades easier.
[0034] In a further improvement, the configuration information module stores complete LVDS display configuration information, including display manufacturer, model, resolution, timing parameters and pin definitions. The main processor can directly obtain detailed configuration information without additional storage or querying, thus speeding up system startup and configuration.
[0035] In a further improvement, the configuration information module only stores the type code of the LVDS display screen; the main processor has a built-in storage unit for storing detailed configuration information corresponding to each type code; the main processor is used to retrieve the corresponding detailed configuration information from the built-in storage unit according to the read type code, which reduces the storage capacity requirement of the configuration information module and lowers the cost. At the same time, the main processor can quickly query and retrieve detailed configuration information through the type code.
[0036] Furthermore, the communication interface between the main processor and the configuration information module is I2C, SPI, or a single-bus interface, providing a variety of communication interface options to adapt to different application scenarios and needs, thereby improving the system's compatibility and scalability.
[0037] Specifically, it also includes the LVDS port display screen self-adaptation method, the method of which is as follows:
[0038] Step 1: System power-on initialization;
[0039] Step 2: The main processor reads the configuration information stored in the configuration information module through the communication interface;
[0040] Step 3: The main processor configures the signal switching logic circuit according to the read configuration information;
[0041] Step 4: After configuration, the main processor outputs an LVDS signal;
[0042] Step 5: The signal switching logic circuit converts the received LVDS signal into a signal format suitable for the connected LVDS display and outputs it.
[0043] Step 6: The LVDS display receives and displays the converted signal.
[0044] In a further improvement, in step 2, the configuration information module stores the display screen type code, and the main processor queries and retrieves the corresponding detailed configuration information from its built-in storage unit based on the type code.
[0045] As a further improvement, step 3 involves configuring the signal switching logic circuit, including configuring one or more of the following: signal mapping relationships, level conversion parameters, and timing parameters.
[0046] As a further improvement, if the LVDS display screen does not have an integrated configuration information module during the assembly stage, a matching external configuration information module will be selected according to the display screen model and connected to the system.
[0047] Example 2
[0048] Please see Figure 2 The present invention provides a technical solution: an LVDS port display screen self-adaptation system and adaptation method.
[0049] To address the aforementioned issues: during production, different versions of circuit boards and cables need to be prepared for different display models, increasing material management and inventory costs; maintenance personnel must use display screens that are exactly the same as the original equipment for replacement, and if the models do not match, it will lead to display abnormalities or even failure to display, resulting in a lack of flexibility.
[0050] The solution is as follows: An LVDS port display screen self-adaptation system and method. The main configuration information of the display screen is stored in the main processor's storage unit, while the display screen's storage module only records a simple screen type or model code. The main processor reads the display screen type or model code from the display screen side. Then, based on this code, it reads the detailed screen configuration information from its own storage unit. The display screen configuration information module can also communicate directly with the main processor without going through signal exchange logic, and then configure the display screen through the main processor's I / O pins.
[0051] Example 3
[0052] Please see Figure 3 The present invention provides a technical solution: an LVDS port display screen self-adaptation system and adaptation method.
[0053] To address the aforementioned issues: during production, different versions of circuit boards and cables need to be prepared for different display models, increasing material management and inventory costs; maintenance personnel must use display screens that are exactly the same as the original equipment for replacement, and if the models do not match, it will lead to display abnormalities or even failure to display, resulting in a lack of flexibility.
[0054] The solution is as follows: An LVDS port display screen self-adaptation system and adaptation method, which involves configuring an external configuration information module to record the display screen's configuration information. During device assembly, the screen model is manually identified, the corresponding configuration information module is selected, and then connected to the configuration information port of the screen connection cable. The main processor reads the corresponding configuration information through the external configuration information module and then configures the display screen parameters according to the configuration information.
[0055] Working Principle: After the system is powered on, the main processor, signal switching logic circuit, configuration information module, and other components are initialized, including reset operations and register settings. The main processor communicates with the configuration information module through communication interfaces such as I2C, SPI, or a single bus to read the display configuration information stored therein, such as resolution, timing parameters, and pin definitions. If the configuration information module only stores type codes, the main processor queries its internal pre-stored configuration database based on these codes. Based on the read configuration information, the main processor generates corresponding configuration instructions and sends them to the signal switching logic circuit through the communication interface. Configuration instructions include signal mapping relationships, level conversion parameters, and timing parameters. After receiving the configuration command, the signal switching logic circuit performs the corresponding configuration operation. The main processor converts the image or video data to be displayed into LVDS signal format and outputs it through its LVDS signal output terminal. Based on the configuration command provided by the main processor, the signal switching logic circuit performs real-time conversion on the input standard LVDS signal, including data channel remapping, signal level adjustment, and timing fine-tuning, ensuring that its output format fully meets the requirements of the target LVDS display screen. The LVDS display screen receives the LVDS signal converted by the signal switching logic circuit through its input terminal, performs decoding and display processing, and finally displays the image or video data on the screen. Through the self-adaptive system, it can adapt to many different models of LVDS displays, eliminating the need to prepare different circuit boards and cables for each model. This reduces the types and quantities of circuit boards, lowering material management and inventory costs. In the maintenance process, precise matching of screen models is not required, reducing spare parts costs and maintenance difficulty. The system automatically completes identification and configuration, requiring no manual settings from the user, thus improving ease of use.
