摘　　要：对4路寻址LCD屏的动态驱动实验教学设计与实践进行了探讨。提出了以AT89C52单片机为核心,2块PCF8566级联驱动4路寻址LCD屏的动态显示的实验方法,制作了实验电路板,并测试了驱动波形。通过对实验系统的构建与实验结果的分析,强化了学生对LCD屏的动态驱动波形的认识。Four-way addressable LCD screen dynamic drive experiment teaching and practice of design in UESTC are discussed. The dynamic driving experimental methods of 4-way addressable LCD screen have been proposed based on an AT89C52 MCU and two cascade PCF8566. The experimental circuit boards are made and driving waveform has been tested. Through construction of the experiment system and the analysis of the experimental results, the students＇s awareness of the dynamic drive waveform of LCD is reinforced.
