摘  要

随着信息技术的快速发展,液晶技术已经形成一个新兴产业,市场空间明朗。越来越多的场合需要用到液晶技术来显示汉字和图片。液晶技术已经成为城市亮化,现代化和社会信息化的一个主要标志。日常生活中我们随处可见液晶技术的身影。
本文针对当前的液晶技术,设计了硬件电路来实现了基于液晶屏的图片与汉字显示,该设计采用AT89C51单片机作为硬件电路的控制核心,由基于控制器为ST7920的QY-12864液晶模块构成液晶显示部分,做到了能够在并行数据传输下控制液晶模块QY-12864,可以实现显示一幅128x64图片和四行16x16的汉字的功能。因为当前液晶显示以及单片机技术的应用广泛,且该课题研究具有很强的实际意义,故发展空间良好。

ABSTRACT

With the rapid development of information technology, LCD technology has formed a new industry, more and more market space clear situations need to use the LCD technology to display Chinese characters and pictures .LCD technology has become the city lighting, modernization and social informatization is a major sign of daily life we can be seen everywhere the form of liquid crystal technology .
This article briefly introduced modern LCD display technology and established a hardware circuit to fulfill an image and charters display.The hardware circuit control core is AT89C51, LCD controller is based on the part of the ST7920 for QY-12864 LCD module composition, realized in parallel data transmission mode control QY-12864 shows a picture of LCD module 128x64 pictures and four rows of 16x16 characters.Because of the universality that liquid crystal using at present, the hardware circuit studying originally has very big expansion space and the result has important application meaning.
