| 摘 要： | 液晶显示模块是由ITO玻璃、液晶驱动芯片、背光模块与软性印刷电路板所组成,基于这种设计架构,当处理器通过输入/输出传输接口传送大量显示数据至液晶驱动芯片的过程中,会产生相当程度的电磁波,并通过模块上的软性印刷电路板（FPC）发散出来,进而影响电子产品内部的组件效能,因此文中将针对电磁干扰的问题说明一些防护的方法。

| Abstract: | The LCD module consists of ITO glass，LCD driver IC，backlight module and FPC．Based on this design structure，the electromagnetic will be radiated via FPC when the MPU delivered great number of display data to LCD driver IC via I／O interface．The electromagnetic interference(EMI)will take place and affect seriously the performance and quality of some components in electronic product．For this reason，some shielding methods for ENI problem will be discussed in this paper． |
