A simulation method is proposed to analyze the optical response characteristics of TFT-LCDs. Our method using an equivalent circuit takes into account the time and voltage dependence of the dielectric constant of the TN-LC cell.

Zusammenfassung:A simulation method is proposed to analyze the optical response characteristics of TFT-LCDs. Our method using an equivalent circuit takes into account the time and voltage dependence of the dielectric constant of the TN-LC cell. We obtain good agreement between simulations of the optical response characteristics of the TN-LC cell and experimental results. The 30 Hz flicker, which appears in the optical rise state of the TFT-LCD, is analyzed by using our method. Our method enables a large amount of calculation of the optical response characteristics of TFT-LCDs at high speed.
