Abstract

In this study, we propose a new pixel edge shape of the fringe field switching(FFS) mode which ensures more stable movement of liquid crystal molecules and higher transmittance at the edge part. the electro optical properties were calculated 3-dimensionally using by commercially available "Techwiz LCD". From the simulation results, we showed that the dynamic stability of liquid crystal molecules was obtained in a new pixel structure. We also revealed that the transmittance of the new pixel structure increased more than 6 % compared to that of the conventional pixel structure.
