LED display several basic parameters

Since led display manufacturers produce different led display, then its basic parameters will be different, but according to categories, we can roughly divide them into three categories, let's study the following several parameters together .

First, basic parameters The basic parameters are the basic parameters of the display. If they are not set correctly, they cannot be communicated or not displayed and the display is not normal. The basic parameters include the display width, control card address, baud rate, IP address, port number, MAC address, subnet mask, gateway, refresh frequency, and shift clock frequency.

Second, auxiliary parameters Auxiliary parameters are parameters set for better display and control, including 4 items of control card name, communication display mark, brightness and switch screen time.

Third, the core parameters The core parameters are the necessary parameters of the display, if the settings are not correct, light is not displayed, and the screen burns. The core parameters include cascade direction, OE polarity, data polarity, display type, color, scan mode, walk sequence, and line sequence.

For the configuration of basic parameters and auxiliary parameters, an input box and a selection box are provided. After the user inputs and selects, the connection display screen can be directly set. For the core parameters, three methods can be used: professional quick check, smart configuration, and external file configuration.

1, professional quick check

For common and commonly used models of outdoor display, the parameters are generally fixed, then can be organized into files or tables in advance, you can choose to load configuration when debugging.

2, smart configuration

For uncommon or indefinable displays, the parameters are unknown. In this case, you can use smart configuration, determine its configuration parameters, and then save it for later use.

3, external file configuration

Imports smart configuration or other built external files into the configuration.

Among the three configuration methods of core parameters, smart configuration is an important configuration method. Its main processes and functions are as follows:

1, start smart configuration.

2, through the wizard type, let the user and the energy-saving led display for human-computer interaction selection, start the intelligent configuration operation, by filling in the initial parameters, determine the OE polarity / data polarity, determine the color, determine the scanning method, determine the order of walking, Determine the order of the line and generate configuration parameters and other steps to complete the determination of the core parameters.

3, return to the intelligent configuration parameters.

4, connect the display, set the parameters.

5. If it is correct, perform the output parameter operation.

6. Select an external file and save it for download later. At this point, complete the display smart configuration.

To sum up, a display screen needs to be properly configured with more than 20 parameters to light up. Its complexity and complexity can be imagined. Due to the relatively high manufacturing cost of the led display screen, if it is not set correctly, it will not be displayed when it is light, and it will burn the display screen when it is heavy, causing major economic losses and delays in the construction period. Therefore, some LED control software is prudent and secure, and the design is complex and inconvenient to use is also understandable.
