Analyzing the EMC performance of an automotive display module through 3D electromagnetic simulation

With increasing market demand for the automotive instrumental clusters to be more interactive and scalable, the trend is now moving towards a full digital display system. Thus, there is more electromagnetic compatibility (EMC) design focus on the display module. In EMC design, it would be inadequate if signal & power integrity designs are not taken into considerations. In this paper, the use of 3D full wave modeling is applied on an automotive display module. Through virtual prototyping, in depth analysis and comparing the effectiveness of the display module with and without proper signal & power integrity design considerations is made possible.
