Abstract
In this work, the eight cases of independently designed flexible printed circuit (FPC) for a large-size and high-resolution liquid crystal display (LCD) TV module were analyzed in a perspective of signal integrity (SI) by comparing the eye-opening simulation results from the measured channel models. Although the case of two-layer FPC with a ground plane has advantages in terms of impedance matching and crosstalk mitigation, the case of single-layer FPC was found to have better SI performance than the two-layer FPC as long as crosstalk is properly suppressed by optimizing the layout design even if the impedance matching is not perfectly satisfied.
