There are as many as 20 parameter configurations of an LED display screen. Only when they are configured correctly can they light up normally to ensure the stable operation of the display screen. Therefore, the production process is quite cumbersome and complicated. From this, you can also know why the LED The price of the display screen is generally relatively high, and if there is an incorrect setting, the display screen will not be displayed at the slightest degree, and the display screen will be burned in the worst case, causing major economic losses and delays in the construction period.
Therefore, for some outdoor LED display control software, it is understandable that the design is complicated and inconvenient to use for the sake of prudence and stability. According to the different LED display manufacturers, the number of parameter items of the LED screen will also be different. After analysis and classification by the Siweixin Optoelectronics Engineering Department, the parameters of the LED outdoor display control software can be divided into basic parameters, auxiliary parameters and core parameters Three kinds:
First, the basic parameters
The basic parameters are the basic parameters of outdoor full-color LED screens. If they are not set correctly, they cannot communicate or display and display abnormally. The basic parameters include display width and height, control card address, baud rate, IP address, port number, MAC address, subnet mask, gateway, refresh frequency, and shift clock frequency, totaling 10 items.
Second, auxiliary parameters
Auxiliary parameters are parameters set for better display and control, including 4 items including control card name, communication display mark, brightness, and switching screen time.
Third, the core parameters
The core parameters are the necessary parameters for the outdoor LED display. If the settings are not correct, it will not display at all, and it will burn the screen. The core parameters include 8 items including cascade direction, OE polarity, data polarity, display type, color, scanning mode, walking order and row order.
LED display control software parameters and configuration methods:
For the configuration of basic parameters and auxiliary parameters, an input box and a selection box are provided. After the user inputs and selects, connect the display screen to directly set it. As for the core parameters, you can use three methods: professional quick search, smart configuration and external file configuration.
1. Professional quick check
For common and commonly used models of display screens, their parameters are generally fixed. At this time, they can be organized into files or tables in advance, and you can choose to load the configuration when debugging.
2. Intelligent configuration
For unusual or uncertain display screens, the parameters are unknown. At this time, intelligent configuration can be used to determine the configuration parameters, and then save them for later use.
3. External file configuration
Import the smart configuration or external files constructed in other ways into the configuration.
Among the three configuration methods of core parameters, smart configuration is the more important configuration method. Its main processes and functions are as follows:
1. Start smart configuration.
2. Through the wizard, let the user and the display screen to select the human-computer interaction, and start the intelligent configuration operation, by filling in the initial parameters, determining the OE polarity/data polarity, determining the color, determining the scanning method, determining the walking order, and determining the line Steps such as sequence and generating configuration parameters complete the determination of core parameters.
3. Return to the smart configuration parameters.
4. Connect the display screen and set the parameters.
5. If it is correct, perform the output parameter operation.
6. Select an external file and save it for later download. At this point, the intelligent configuration of the display screen is completed.
The basic parameters of the entire LED outdoor display control system have been analyzed. I believe you must have a deeper understanding of the LED display. For more related outdoor LED display parameters, prices and other questions, please feel free to contact us.
