LCD12864原理与应用1、LCD12864简介：LCD12864分为两种，带字库的和不带字库的，不带字库的液晶显示汉字的时候可以选择自己喜欢的字体。

而带字库的液晶，只能显示GB2312字体，当然也可以显示其他的字体，不过是用图片的形式显示。

下面介绍不带字库的LCD12864,以Proteus中的AMPIRE128×64为例，如下图所示，它的液晶驱动器为KS0108。

引脚功能：引脚符号状态引脚名称功能，输入芯片片选端，都是低电平有效CS1=0开左屏幕，CS1=1关左屏幕CS2=0开右屏幕，CS2=1关右屏幕RS输入数据/命令选择信号RS=1为数据操作，RS=0为写指令或读状态RW输入读写选择信号R/W=1为读选通，R/W=0为写选通E输入读写使能信号在E下降沿，数据被锁存(写)入液晶，在E高电平期间，数据被读出DB0—DB7三态数据总线数据或指令的传送通道输入复位信号，低电平时复位复位时，关闭液晶显示，使显示起始行为0，可以跟单片机的复位引脚RST相连，也可以直接接VCC，使之不起作用V0液晶显示器驱动电压-Vout-10V LCD驱动负电压与带字库的液晶不同，此块液晶含有两个液晶驱动器，每块驱动器都控制64*64个点，分为左右两个屏幕显示，总共为128*64个点（即有128×64个点）。

这就是为什么AMPIRE128*64有CS1和CS2两个片选端的原因。

此液晶有8页，一页有8行点阵点，左右各64列，共128列。

如下图所示：2、LCD12864中的几条重要指令（一）行(line)设置命令:由此可见显示的起始行地址为0XC0，共64行，有规律地改变起始行号，可以实现滚屏效果。

（二）页(page)设置指令:起始页地址为0XB8，因为液晶有64行点，分为8页，每页就有8行点。

（三）列(column)地址设置指令每块驱动器的列地址都是从0X40到0X7F，共64列，所以此液晶共有128列点。

点阵LCD12864的显示原理（不带字库）在数字电路中，所有的数据都是以0和1保存的，对LCD控制器进行不同的数据操作，可以得到不同的结果。

对于显示英文操作，由于英文字母种类很少，只需要8位（一字节）即可。

而对于中文，常用却有6000以上，于是我们的D OS前辈想了一个办法，就是将ASCII表的高128个很少用到的数值以两个为一组来表示汉字，即汉字的内码。

而剩下的低128位则留给英文字符使用，即英文的内码。

那么，得到了汉字的内码后，还仅是一组数字，那又如何在屏幕上去显示呢？这就涉及到文字的字模，字模虽然也是一组数字，但它的意义却与数字的意义有了根本的变化，它是用数字的各位信息来记载英文或汉字的形状，如英文的'A'在字模的记载方式如图1所示：图1 “A”字模图而中文的“你”在字模中的记载却如图2所示：图2 “你”字模图12864点阵型LCD简介12864是一种图形点阵液晶显示器,它主要由行驱动器/列驱动器及128×64全点阵液晶显示器组成。

可完成图形显示，也可以显示8×4个(16×16点阵)汉字。

能够显示 8× 4 行 16× 16 点阵的汉字 . 也可达成图形显示 . 低电压低功耗是其又一明显特色。

由该模块构成的液晶显示方案与同种类的图形点阵液晶显示模块对比，无论硬件电路构造或显示程序都要简短得多，且该模块的价钱也略低于同样点阵的图形液晶模块。

基本特征 :低电源电压（ VDD:+3.0--+5.5V）显示分辨率 :128 × 64 点内置汉字字库，供给8192 个 16× 16 点阵汉字 ( 简繁体可选 )内置 128 个 16× 8 点阵字符2MHZ时钟频次显示方式： STN、半透、正显驱动方式： 1/32DUTY， 1/5BIAS视角方向： 6 点背光方式：侧部高亮白色 LED，功耗仅为一般 LED的 1/5 —1/10 通信方式：串行、并口可选内置 DC-DC变换电路，无需外加负压无需片选信号，简化软件设计工作温度 :0 ℃ -+55℃ ,储存温度:-20℃ -+60℃二、方框图3、外形尺寸图三、模块接口说明* 说明 1：如在实质应用中仅使用串口通信模式，可将PSB接固定低电平，也能够将模块上的J8 和“ GND”用焊锡短接。
