Abstract :
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.
