Experimental study for the conditions of analog switching in ferroelectric liquid crystal cells

The authors study the effect of the spontaneous polarization PS of a ferroelectric liquid crystal mixture with compensated helix and of the thickness of the alignment layer da on the analog switching in a cell. The quality of analog switching is established in terms of its contrast ratio, texture in the dark state, and the electrostatic energy. The latter approximates to PS da for da d thickness of the ferroelectric liquid crystal cell layer . © 2007 American Institute of Physics. DOI: 10.1063/1.2767210
