Paper Abstract

Electric-field-induced effective anchoring energy in nematic liquid crystal is investigated taking surface and flexoelectric polarization into consideration. The analytical expressions of effective anchoring energy for both bottom and upper substrate, containing these two polarizations, are derived. The effective anchoring strength for both bottom and upper substrate is also obtained by means of a systematic method, which is relevant to magnitude of two polarizations and determined by the applied voltage U. Applying the obtained expressions into an original weak anchoring hybrid aligned nematic cell, the effective anchoring strength are determined with the different magnitudes of two polarizations and the different applied voltage U.
