液晶汉字显示的原理与设计

以液晶显示模块MGLS-12032A为例,给出了一种单片机控制的液晶汉字显示系统。首先简要介绍了MGLS-12032A的结构及其显示原理,然后叙述了单片机控制的硬件接口电路,最后对ASCII码、HZK16文件的排列标准、汉字点阵字模的提取流程进行了分析和模拟,同时给出具体的模拟结果。实践证明,该设计具有一定的使用价值和工程实践指导意义。

Principle and Design of LCD Chinese Character Display

The use of LCD is becoming more and more popular in a good many MCU applications. The paper gives an example of Chinese character display system based on MGLS-12032A. Firstly, it introduces the configuration and the display principle briefly, which is followed by the introduction of hardware design. In the end, it presents the analysis and simulation of ASCII code, the arrangement standard of HZK16 file and the flow of Chinese characters lattice in detail, at the same time, it presents the result of simulation. Substantial evidence shows that the design has value of use and guidance meaning in a way.
