The LED display control card is the core component of the LED graphic display. It is responsible for receiving the picture display information from the serial port of the computer, placing it in the frame memory, and generating the serial display data and scanning control required by the LED display according to the partition drive mode. timing. The effect of the LED display screen is related to it.

4. How to choose the LED display control card?
First, understand the specifications and dimensions of the LED display screen, calculate the number of points, and know the effect you need, whether it is synchronous or asynchronous, and whether secondary development is required; then, determine the synchronous and asynchronous, determine the effect, determine the range of points, and determine the price range, Finally, determine the card; choose the most suitable control card, not necessarily the most suitable one with high price and good quality.
