图形点阵液晶显示模块使用手册 MS12864F

一.概述

MS12864F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±10% ,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。 5.简单的操作指令。
