In order to gain a small size and low cost display screen and achieve a more abundant display effect, a cylindrical new LED display screen was designed. This screen comes true with a line of SMD LED lightings which is rotated by a DC motor and controlled by ATmega16L which is the key control chip based on AVR MCU. The wireless Lnfrared remote control is used to switch display content at any moment to show different letters, patterns and system time. With the equivalent display effects , using less number of LEDs instead of mass LEDs is achieved. Meanwhile, the screen shows that the angle of view becomes wider, and is up to 360-degree in the process of rotation.%为了使显示屏的体积更小,成本更低,同时又能有较丰富的显示效果,采用AVR微处理嚣ATmegal6L作为核心控制芯片,由直流电机带动一列贴片LED旋转设计了圆柱形LED显示屏,可以由无线红外遥控装置随时切换显示的内容,可显示不同的文字,图案、系统时间等.利用少量发光二极管实现海量发光二极管才能实现的显示屏,同时该屏在旋转过程中显示,使得可视角更广,可以达到360.全方位.
