摘要
主要介绍了TFT-LCD的电磁兼容的基本概念。对引起TFT-LCD电磁环境恶化的原因、干扰源的种类进行了探索,提出了一些有效的电磁兼容设计方法,即从结构设计和电路设计出发,运用屏蔽技术和滤波技术的原理来控制电磁干扰。具体就是采取包括地线设计、布线、滤波、屏蔽等方面的措施,对加固TFT-LCD实施电磁干扰的控制技术,并在实践中取得良好的效果。
This article mainly introduces the basic concept of TFT-LCD＇s electromagnetic compatibility （EMC）. The cause that will make the TFT-LCD＇s electromagnetic environment worsen and the kinds of disturbance sources are explored, and several effective methods of EMC design are introduced. Based on TFT-LCD＇s structural designs and circuit designs, we can use principles of shielding technology and filtering technology to control EMI. Furthermore, some control technology like provided for the rugged rugged TFT-LCD. design of grounding, arrangement cockpit TFT-LCD. Good results of lines, filtering and shielding, are are achieved in resolving EMI for the
