Adopted the modular design, this paper implemented a 16×64 LED dot matrix rolling display screen. It can change display direction by the gesture. In the design, AT89S52 single chip was used as micro controller, the 74HC154 decoder and 8550 PNP transistor as row driver circuits, photocell control switch as scrolling direction controller, and 16 pieces of 8×8 LED as the 16×64 dot matrix characters rolling display screen. The software and hardware tested results shows that this design can change display direction accurately according to the user gestures. And the Chinese characters is clear, no crosstalk, no ghosting.
