LCD资料
一.概述
12864-10是一种图形点阵液晶显示器。
它主要采用动态驱动原理由行驱动器、控制器和列驱动器三部分组成了128（列）×64（行）的全点阵液晶显示。
此显示器采用了SMD的硬封装方式，通过导电橡胶和压框连接LCD,使其寿命长，连接可靠。
二.特性
1.工作电压为+5V,可自带驱动LCD所需的负电压。
2.全屏幕点阵，点阵数为128（列）×64（行）,可显示8（/行）×4（行）个（16×16点阵）汉字，也可完成图形，字符的显示。
3.与CPU接口采用4条位控制总线和8位并行数据总线输入输出，适配
Inter8080系列时序。
4.内部有显示数据锁存器，和用于文本显示的6×8和8×8的字符库。
