Abstract :
In this paper, the effectiveness of bulk gasket and shield cover is studied. Those materials are widely used in LCD TV, because they strengthen the PCB ground and suppress EMI radiation. In this paper, shielding and grounding effect by those materials is examined by EM field simulation and the result is compared with test one. Finally, it is verified that the simulation result is in good agreement with test result.
