¥ 模块使用的注 意事项
表１ 片选信号组合
模块中的控制驱动电路是低压微 功耗的 ＣＭＯＳ 电路，极易被静电击穿， 是一种不可修复的损坏，而人体有时 会产生高达几十伏或上百伏的高压静 电，所以在操作装配以及使用中都应 极其小心严防静电。
液晶模块可选用带背光的型号。 大部分为 ＬＥＤ 背光方式供电的电源为 ３．８～４．３Ｖ直流电源，严格限制５Ｖ 电源 直接供电，否则不仅会增加功耗，更会 增加损坏背光灯的可能性，缩短液晶模 块的使用寿命，推荐电压小于等于４．１Ｖ。
点，系统集成商可以更快将产品推出
另外采用该协议还可为系统添加
市场。相对于需要为 ８ 位及 １０ 位平面 全新功能，如美国国家半导体的线路
显示器构思不同系统结构的厂商来说， 延迟补偿功能可以分别为每一列驱动

Design and Handling Precaution1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. The LCD panel is made by glass. Any mechanical shock (eg. dropping form high place) will damage the LCD module. Do not add excessive force on the surface of the display, which may cause the Display color change abnormally. The polarizer on the LCD is easily get scratched. If possible, do not remove the LCD protective film until the last step of installation. Never attempt to disassemble or rework the LCD module. Only Clean the LCD with Isopropyl Alcohol or Ethyl Alcohol. Other solvents (eg. water) may damage the LCD. When mounting the LCD module, make sure that it is free form twisting, warping and distortion. Ensure to provide enough space (with cushion) between case and LCD panel to prevent external force adding on it, or it may cause damage to the LCD or degrade the display result. Only hold the LCD module by its side. Never hold LCD module by add force on the heat seal or TAB. Never add force to component of the LCD module. It may cause invisible damage or degrade of the reliability. LCD module could be easily damaged by static electricity. Be careful to maintain an optimum anti-static work environment to protect the LCD module. When peeling off the protective film from LCD, static charge may cause abnormal display pattern. It is normal and will resume to normal in a short while. Take care and prevent get hurt by the LCD panel sharp edge. Never operate the LCD module exceed the absolute maximum ratings. Keep the signal line as short as possible to prevent noisy signal applying to LCD module. Never apply signal to the LCD module without power supply. IC chip (eg. TAB or COG) is sensitive to the light. Strong lighting environment could possibly cause malfunction. Light sealing structure casing is recommend. LCD module reliability may be reduced by temperature shock. When storing the LCD module, avoid exposure to the direct sunlight, high humidity, high temperature or low temperature. They may damage or degrade the LCD moduleURL: Document Name: LM19264ACW-Manual-Rev0.1.DOC Page: 10 of 10。

The user may choose the mode that is most appropriate for the application.Overwrite Mode:******************************************************************************************* from left to right, if it is at the end of the Line, it moves to the beginning of the other line. Characters are displayed at the Current cursor position, overwriting what is originally there, the cursor is then moved to the next position.Vertical Scroll Mode:If the cursor is at the upper line it behaves like the overwrite mode. When it is at the end of the lower line, the next character would scroll the content of the lower line to the upper line, the lower line is cleared and the cursor is moved to the beginning of the lower line.Horizontal Scroll Mode:In this mode the cursor stays in what ever line it is at, unless changed by cursor Movement commands. When the cursor is not at the end of the line, the input Character is displayed at current cursor position, the cursor is then moved right. Once at the end of the line, subsequent character input would scroll the current Line left one position, and the new character is displayed at the end position. There is also a command, ESC W, to set display window in this mode. The effective display line would be limited within the window as defined by the command.String Mode:This mode is perhaps the simplest used. The two display lines are treated independently. Only two commands, ESC Q A and ESC Q B, are needed. ESC Q A followed by a string on the upper line, left aligned. A CR (0DH) character terminates the command. If the string is less than twenty characters in length, the rest of display line is padded with plank. ESC Q B does the same for the lower display line. The only other commands active in this mode are CLR and CAN. CLR would clear the display and change the LCD into overwrite mode. CAN clears the last line that was changed and change the LCD into overwrite mode. The initialization command, ESC @, has no effect in this mode.11.

图形LCD模块ACM19264ASB的汉字显示
1引言在基于单片机的智能系统中，汉字显示模块是很重要的一个组成部分，它应用广泛、操作容易、调试简便。
然而，在单片机上显示汉字也存在几个问题。
首先，单片机资源有限，我们不能为了显示汉字占用太多的资源；其次，汉字存储读取比较繁琐，使用不方便；第三，汉字是通过点阵显示出来的，往往与LCD写入方式不一样，这就得进行转换和调整。
值得注意的是，基于单片机的汉字显示不能在字符LCD上实现。
使用图形LCD有很多优点，不仅能显示汉字，而且可以实现汉字动态移动和上下滚屏，实现汉字与图形的混合显示，同时功耗低。
2基于单片机的汉字显示原理2.1汉字字模汉字一般是以点阵式存储的，如16×16，24×24点阵（即汉字的字模），每个汉字由32字节（16点阵）或72字节（24点阵）描述。
根据汉字的不同字体,也可分为宋体字模、楷体字模、黑体字模等等。
汉字的字模其实是汉字字形的图形化。
对于16点阵字模，就是把汉字写在一个16×16的网格内，汉字的笔画能过某网格时该网格就对应1，否则该网格对应0，这样每一网格均对应1或0，把对应1的网格连起来看，就是这个汉字。
汉字就是这样通过字节表示点阵存储在字库中的。
为了方便查找所需汉字的汉字字模，每个汉字都与一个双字节的内码一一对应。
通过汉字的内码可以计算出它的点阵起始字节。
现以16点阵为例说明。
先由内码计算出它在汉字库中的区位码，计算公式为：区码=内码第一字节－160位码=内码第二字节－160再由区位码可以得到它在汉字库中字模第一个字节的位置:(区码×94＋位码)×32 于是，可以向后连续读出由32个字节组成的该字的点阵数据。
2.2汉字显示汉字占用资源太多（如16点阵，每个汉字就需32字节），因而通常把汉字库放在EEPROM里，需要显示某个汉字时，先算出它的区位码，再求出点阵起始位置，从EEPROM 中顺序调出该字的点阵数据，存在缓冲区里，最后依次送往LCD显示，描出该字。
