图形（点阵）液晶模块的应用越来越广泛，因此液晶模块的应用开发也越来越倍受人们关注。为此，本工作室提供了一整套图形液晶显示系统及完全解决方案，以方便液晶模块的应用和开发。本工作室提供的液晶显示系统是一套基于128x64的图形液晶模块，依据本工作提出的汉显原理及汉字字模工具软件的显示系统。本系统由计算机处理好显示数据，然后由计算机串行总线传送显示数据到显示控制器，再由控制器通过并行总线传送数据到128x64液晶显示模块，进行图形或汉字的显示。

    计算机（汉字字模工具软件）->点阵数据->串行总线->显示控制器->并行总线->液晶显示模块

    图形液晶显示系统及解决方案包括：显示控制器 + 主控芯片固件程序 + 128x64图形液晶显示模块 + 汉字字模点阵数据批量生成工具 + VC++应用示例程序及源代码。 咨询或购买请拔打本站注册热线：13862090275
    接下来简单介绍一下相关部分：
 1.计算机软件Demo版及源代码 (源代码下载)，当用鼠标点击相应的按钮时，计算机软件将汉字字模产生的显示数据传送到显示系统，显示系统将显示相应的图象或汉字。Demo软件画面如下：

 2.显示控制器，由本工作室开发完成，包含硬件和固件两部分。显示控制器用来接收计算机传送的显示数据，并把显示数据送到液晶显示模块进行显示。显示控制器采用串口进行数据传输。

 3.图形液晶模块，此模块由液晶生产厂商提供。

    本液晶显示系统从图形数据转换到数据传输，再到液晶模块画面显示，每一步都提供了具体的实施步骤，是一个较完全的图形点阵液晶显示解决方案。用户可依据以下的步骤对本系统进行应用或做二次开发：
    1.首先通过简单的图形编辑软件，如画图，进行图形设计，图形的大小必须是128x64（因为本系统采用128x64的图形液晶模块），图形设计须使用单色设计，设计完成后保存为24位位图文件，这里假设保存 为：a.bmp。
    2.把设计完成的位图文件a.bmp导入汉字字模点阵数据批量生成工具，字模软件设置为“ZN扫描”，字节位倒置，C语言数组形式。设置完成后，创建图形点阵数据。
    3.把创建好的数据拷贝到应用程序代码中，由程序把相应的图象点阵数据传输到图形液晶显示系统。
    具体的VC++应用代码如下：
HANDLE hDevice;
DWORD nWrite;
unsigned char lcd[1024]={// 本数组是图象点阵数据，由汉字字模软件工具创建
