laser is easy to couple with electromagnetic interference
so as to affect the normal work of the laser. Therefore
this paper explores the prediction method of Electromagnetic Compatibility (EMC)for the LCD module under transient irradiation in an electromagnetic field. The coupling mechanism of electromagnetic interference received by the LCD module integrated in the laser system was analyzed. On the basis of the coupling of field and line
the field line electromagnetic interference of the LCD module was analyzed and calculated by using the BLT equation in the Taylor form
then
the prediction results were verified by several experimentally. The experimental results show that the interference voltage produced by connect cables coupled with electromagnetic fields on the data lines of LCD display module is 1 V
and exceeds the noise margin of the circuit. So the EMC control measures must be taken to ensure the performance of the LCD module. Moreover
the verification experiments indicate that prediction results for the EMC has correctly reflected the actual EMC performance of LCD module. The method has a guiding significance for prediction and design of EMC of electrical equipment in high-power TEA CO
