The calculation of the LED display receiving card is mainly based on several key factors: the total resolution of the LED display, the maximum supported resolution of a single receiving card, and the configuration of the LED module. Understanding these factors will help you determine how many receiving cards are needed to drive the entire LED display. Here are the basic steps to count the number of cards received:
First of all, you need to know the total number of pixels (i.e., total resolution) of the entire LED display. This can be calculated by multiplying the number of width pixels of the display by the number of height pixels. For example, if the resolution of an LED display is 1920x1080 pixels, then its total number of pixels is 2073600.
Next, look at the specifications of the receiving card you plan to use to see the maximum supported resolution. The maximum resolution supported by different models of receiving cards may differ. For example, a receiving card may support a resolution of up to 1024x512 pixels.
The LED display is composed of multiple LED modules, each with its own pixel configuration. Understanding the pixel configuration of your LED module (e.g., 128x64 pixels) will help you better plan the distribution of receiving cards.
Based on the above information, you can calculate the number of cards you need to receive. Divide the total number of pixels across the display by the maximum number of supported pixels for a single receiving card, and the result is the number of receiving cards theoretically required. This number may then need to be adjusted depending on the actual layout and wiring of the LED module.
Example calculations: Assuming that the total resolution of an LED display is 1920x1080 pixels (the total number of pixels is 2073600), each receiving card supports a maximum of 1024x512 pixels.
Total pixels: 2,073,600 pixels.
Number of pixels supported by a single receiving card: 1024x512 = 524288 pixels.
Number of receiving cards required = Total number of pixels Number of pixels supported by a single receiving card = 2,073,600 524288 4
This means that you need at least 4 receiving cards to drive the entire LED display. However, depending on the layout and wiring of the LED module, more receiving cards may be required to ensure even signal distribution and display.
Redundant design: To improve the reliability of your system, you may want to consider adding an additional receiving card as a backup.
Signal distribution: Depending on the needs of the display content and signal distribution, the number and layout of the receiving cards may need to be adjusted.
Finally, it is recommended to consult the technical support of the LED display and receiving card provider to ensure that the most suitable number and model of receiving card are selected according to the specific display needs and configuration.
