| 摘 要： | 提出并实现了一种基于ARM（LPC2148）和TFT液晶模块的UCDOS汉字库加载及字模调用显示的方法。分析了如何把通过字模提取软件获得的点阵代码转换成TFT液晶屏幕的像素显示的方法。针对自带字库的液晶模块（TFT-LCD基本不自带）价格较贵的特点，给出了在ARM中加载汉字库的过程以及如何调用库中的字模代码驱动TFT液晶模块。实验表明，该方法切实可行，对基于ARM的嵌入式系统人机界面的开发也具有一定的参考价值。

| Abstract: | A kind of loading and display method of Chinese character library based on ARM and TFT-LCD was proposed in this paper. Firstly, how to transfer the information achieved by software of character-mode into the pixel display of TFT-LCD was analyzed. Secondly, for the peculiarity that LCD with Chinese character library is expensive （TFT-LCD had not schlep Chinese character library itself）, the process of loading the library in an ARM system and the method of transferring the character-mode code to drive the TFr-LCD were afforded. The result of experiment showed that the method would be viable in application. The method had definite reference value for the interracial development of ARM system. |
