Abstract
Transmittance of liquid crystal display (LCD) is accurately characterized by using a rational fraction approach to extract complex multi-poles corresponding to a modified Drude-Lorentz dispersive model in the time-domain simulation. Here, the multi-pole fitting accuracy to the measured complex refractive indices of color filters and polarizers with low absorption coefficients and high noise levels is significantly improved with the suggested multi-pole fitting algorithm. Then, the transmittance and power distribution of LCD for oblique incidence are analyzed with high angle accuracy, and the color shift arising from the misalignment between the color filter and thin-film transistor substrates is effectively evaluated.
