摘　　要：目的为设计一种任意画面可逐行切换的LCD显示驱动硬件接口电路。方法采用单片机80C51控制基于NT7532芯片的点阵式液晶显示器M0089,用汇编语言实现了逐行切换。结果实现了两个任意画面的逐行切换显示,对应用到FED显示驱动的可行性进行了讨论。结论用单片机控制可实现画面的逐行切换。Aim To design a hardware interface circuit of LCD drive,which can switch line-by-line between two arbitrary pictures.Methods Emploging a 80C51 singlechip to control Matrix LCD M0089 based on NT7532 chip,and using assemble language to achieve the line-by-line switch.Results The line-by-line switch display of two arbitrary pictures is carried out,and the application feasibility in FED drive is discussed.Conclusion Singlechip control can actualize the line-by-line switch between two pictures.
