了解点阵液晶显示实验的工作原理掌握点阵液晶显示实验程序的设计方法.本实验板中使用的是内置12864A 的液晶屏12864A 由两片带控制器的列驱动电路

KS0108 和一片行驱动电路KS0107 组成主要的硬件电路另外还可以附加负压发生电路

显示方面由一片128*64 点的液晶片组成-Dot-matrix liquid crystal display experiments to understand the working principle of the experiment have dot-matrix liquid crystal display design process. The experimental plate is used in the 12864A LCD built-12864A from the two controllers out with KS0108 driver circuit and a line driver circuit KS0107 major hardware components also occurred in the circuit can be attached to negative pressure display 128* 64 from a point of the composition of the liquid crystal film
