智能大屏幕动态显示系统的设计

Design of a intelligent large-screen dynamic display system

智能大屏幕显示系统既能显示固定内容,又能显示随机内容.固定内容存储在单片机的E2PROM中,供长期显示,随机内容可由PC机编辑,以串行方式发送给单片机,使单片机的功能得以充分发挥,同时也将PC机从显示工作中解放出来,提高了微机的利用率.显示部分采用动态显示技术,既保证了智能大屏幕高亮度、无闪烁等优点,又降低了功耗,提高了系统的性价比.

The intelligent large-screen display system can display fixed messages and random messages. The former is stored in E2PROM,and the latter is edited in PC,then communicated to single-chip microcomputer in serial mode.The system not only takes full advantage of single-chip microcomputer,but increases efficiency of PC.It is used in the display system so that the LED large-screen is assured of high brightness without twinkling,and the energy consumption is cut down.
