基于ARM9的LCD/LCM小电流测试方法研究

Study on Method of Small Current Examination Based on ARM9 in LCD/LCM Inspecting

详细讨论了在LCD/LCM检测过程中,微小电流的检测和处理的原理与方法,特别是在小电流的放大和改善待测小信号质量的方法上。在此基础上设计了基于嵌入式ARM9的硬件检测电路,并进行了相关的试验且得到了理想的效果。

The paper discusses the small current examination and processing principle and method, partially amplifying small current and improving the quality of small signal in the LCD/LCM examination process. So designs a detection circuit based on ARM9 to examine it. Finally, carries the related experiment and obtaines the desired results.
