Paper Abstract

We demonstrate a hysteresis-free PSBP-LCs by inveistagating crystal growth and phase separation process of PSBP-LCs. By enlarging the domain size and uniformity of the crystal orientations of PSBP-LC, the hysteresis of PSBP-LCs can be eliminated. The large domain size and uniform crystal orientations of PSBP-LCs reduce the mismatch of the crystal orientations of PSBP-LCs. Based on this study, we also demonstrate a hysteresis-free electro-optical switch using dye-doped PSBP-LCs. Hysteresis-free PSBP-LC is important in many applications, such as displays, electro-optical switches, and electrically tunable focusing lenses.
