A new algorithm of dynamic display for the large LED screen of multi-scanning-beam

In this paper, a new algorithm of dynamic display is introduced for design of the large LED screen, it employs the image masking technology for multi-scanning-beam displaying dynamically. In order to verify the effectiveness of our new algorithm, a LED display system is designed and implemented with the microcontroller of STC12C5A60S2. The result shows that this algorithm improves the performance of dynamic display without any screen flickers, it doesn't require a large of external RAM or FLASH memory and will reduce the hardware cost of LED display system.
