[LCT5-2(Invited)]Liquid Crystal Reorientation with Ultra-Low Driving Voltage between Strong and Weak Anchoring Surfaces

Liquid crystal,Weak anchoring,Twisted nematic,Hybrid aligned nematic,Low driving voltage
Hybrid aligned cells were designed using strong and weak polar anchoring surfaces. When the weak anchoring strength was less than critical one, the liquid crystal director distribution changed to usual homogeneous and 90 degree twisted nematic orientations, which LC cells had no threshold voltage and very low driving voltage.
