目前人类社会已步入了信息时代，信息产业已成为衡量一个国家现代化水平的重要标志。人们信息的获取有80%来自视觉，各种信息最终都要通过信息显示来实现人机交换。显示器是人与机器沟通的重要界面，早期以显像管CRT 显示器为主，但随着科技不断进步，近年来，由于液晶显示器（LCD）具有轻薄短小、低耗电量、无辐射危险、平面直角显示以及影像稳定不闪烁等优势，并且在价格不断下跌的情况下，逐渐取代CRT之主流地位。本论文提出了以ARM7控制液晶显示模块实现显示功能的技术方案，针对工业控制，手持设备和仪器仪表设备常用的DM12232F点阵图形液晶显示模块，与其他液晶显示模块相比，它具有接口简单，性价比高的优点。
本论文设计了控制电路的硬件连接图，根据液晶显示模块DM12232F和LPC2138的管脚功能，通过研究芯片的内部时序完成液晶显示的驱动子程序。设计结果表明液晶显示模块获得了理想的显示效果，而作为一种通用模块它是可移植的。本设计是在Keil uVision2开发环境下采用C语言设计并实现液晶显示的驱动。

Abstract
At present，human society has entered the information age, information industry has become an important symbol to measure a country's modernization level. The 80 percent of information that people collect is from people’s eyesight, information will eventually realize human-machine exchange through information display. Display is an important communication interface between human being and machine, the early display is mainly kinescope CRT, but with the progress of science and technology in recent years, since liquid crystal display (LCD) has many advantages such as light weight, small size, low power consumption, no radiation hazard, flat rectangular display , stable image and so on, and its price is dropping continuously, LCD is gradually replacing CRT's mainstream status. This paper proposes an ARM7 LCD module implements display technology control procedures. According to industrial control, Hand-held devices and instrumentation equipment, commonly used DM12232F bitmap graphics LCD module. Compared with other LCD module, it has a simple interface, the advantages of high performance/price ratio.
This paper designed the control circuit of the hardware connection diagram. According to LCD module DM12232F and LPC2138 tube foot function, Through the research microchip finish liquid crystal display inside drivers .The results of the experiment show that the LCD module has an ideal displaying function both in the local display and communication applications, and as a general module it is transplantable, This design is uVision2 development environment, you can use C language design and realize the liquid crystal display driver.
