A nematic liquid crystal with high, positive dielectric anisotropy (5CB) has been studied under the influence of the combined action of a dc and an ac electric field. Broad frequency, voltage, and cell thickness ranges were considered. Pattern morphologies were identified; the thresholds and critical wave numbers were measured and analyzed as a function of frequency, dc-to-ac voltage ratio, and thickness. The current-voltage characteristics were simultaneously detected.
一种具有高正介电各向异性的向列型液晶(5CB)在直流电场和交流电场的联合作用下进行了研究。考虑了较宽的频率、电压和盒厚范围。识别了图案形态;测量并分析了阈值和临界波数随频率、直流与交流电压比以及厚度的变化关系。同时检测了电流-电压特性。
