图形点轨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。它重要采用动态驱动原3动器、控制

器和列驱动器三部分组成了128（列）X64（行）的全点阵液晶显示。此显了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早0%，可自带驱动IX!）所需的负电压。

2.全屏幕点阵，谦阵数为128（列）X64（般,可显示8（/行）X4（行）个

(16X

16点阵）汉字，也可完毕图形，字符的显示。

3.与CPU接口采用4余位控制总线和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6X8和8X8的字符库。

5.简朴的操作指令°
