【摘要】 以某厂家的液晶显示器为例,探讨此类高频电子产品EMC分析和EMI抑制的方法,并提出了改进方案。具体介绍了PCB板上的EMC设计,分析了液晶显示器中易被人们忽视的各种EMI“天线”,并提出了抑制方法。所提EMC设计方法同样适用于其它高频电子产品。更多还原

【Abstract】 This paper analyses the electromagnetic compatibility(EMC)of an LCD display and provides some improvement measures.The discussion about EMC analysis and design is completed in two parts:One is about EMC design on PCB and the other discusses various kinds of″antennas″in an LCD display which are easy to be ignored.The methods of EMC design given in this paper are also applicable to other electronic products operating at high frequencies.[更多还原
