产品概述
LCD12864 液晶是一种具有 4 位 / 8 位并行、2 线或 3 线串行多种接口方式,内部含有国际一级、二级简体中文库的点阵图形液晶显示模块;其显示分辨率为 128 * 64,内置 8192 个 16 * 16 点汉字,可构成全中文人机交互图形界面。可以显示 8 * 4 行 16 * 16 点阵的汉字,也可完成图形显示,低电压低功耗是它的显著特点。
产品参数
- 宽电压范围:VDD:3.3V - 5.5V
- 显示分辨率:128 * 64
- 内置汉字字库,提供 8192 个 16 * 16 点阵汉字
- 内置 128 个 16 * 8 点阵字符
- 时钟频率:2 MHz
- 视角方向:6 点
- 背光方式:侧面高亮白色LED,功耗仅为普通LED的1/5 - 1/10
- 通讯方式:串行、并行可选
- 内置DC - DC转换电路,无需外加电压
- 工作温度:0℃ - 55℃
- 存储温度:-20℃ - +60℃
- 外形尺寸图
使用方法
声明:此款 LCD12864 液晶为未焊接连接件(排针)的版本,所以购买后您需要自行准备排针焊接,如果您不进行接口焊接,可能会出现接触不良的问题,而导致液晶屏不能正常显示
软件使用
- 图片取模软件使用方法
说明:如果要使用液晶屏显示图片,我们需要使用到图片取模软件,大家在页面最后的相关资料内可以下载
如下图所示为软件的操作界面:
(1)设置输出格式为:C 语言
(2)点击重设参数,设置输出大小,这里使用的是 12864 液晶显示器,所以输出大小为 X:128、Y:64
(3)点击载入图片,将要取模的图片载入到软件中
(4)点击数据保存,将取模后的码值保存到文件中
- 汉字内码提取软件使用方法
(1)在待处理字符串中输入要转换内码的文字,例如输入“奥松机器人”
(2)点击转换,转换结果中会输出内码值,程序中直接使用即可
如图所示:
接口说明
12864 液晶串口接口管脚信号说明 | |||
管脚号 | 名称 | LEVEL | 功能描述 |
1 | GND | 0V | 电源地 |
2 | VCC | +5V | 电源正(3V - 5.5V) |
3 | V0 | - | 对比度亮度调整 |
4 | RS | H / L | 模组片选端,高电平有效 |
5 | R / W | H / L | 串行数据输入端 |
6 | E | H / L | 串行同步时钟:上升沿时读取数据 |
15 | PSB | L | 串口方式 |
17 | RST | H / L | 复位端,低电平有效 |
19 | A | 5V | 背光源电压 +5V |
20 | K | GND | 背光源负端 0V |
注意:1、实际应用中仅使用串口通讯模式,可以将PSB接固定的低电平
2、模块内部接有上电复位电路,因此在不需要经常复位的场合,可以将复位引脚悬空

注意:1、如果在实际使用中仅使用并口通讯模式,可以将PSB连接到固定的高电平
2、模块内部有上电复位电路,所以在不需要经常复位的场合可以将该引脚悬空
3、由于并行方式的接线非常麻烦,所以现在使用较多的为 SPI 的连接方式
