Flexoelectric-Induced Voltage Shift in Hybrid Aligned Nematic Liquid Crystal Cell

摘要

Flexoelectric-induced voltage shift in a weak anchoring hybrid aligned nematic liquid crystal cell is investigatedtheoretically.Based on the elastic theory of liquid crystal and the variation method,the equations for the bulkand the boundary of the cell are derived.By computer simulation,the dependence of the shift voltage on the sum ofthe flexoelectric coefficients and the anchoring energy strength is obtained.As a result,a novel method to determine thesum of the flexoelectric coefficients by measuring the shift voltage is put forward.
