FERROELECTRIC LCD CELL Russian patent published in 2011 - IPC G02F1/135 G02F1/137 

FIELD: physics.

SUBSTANCE: proposed cell comprises two flat translucent plates arranged in parallel one above the other. Polaroids are applied on one side of said plates and translucent current conducting coats connected to alternating voltage source are applied on their opposite side. Cell comprises also ferroelectric liquid crystal (FLC) arranged between said coats of plates to vary its optical anisotropy at electric field effects. FLC layer thickness - d, helicoid pitch- p₀ and boundary conditions defined by factor W_q are selected subject to the following conditions: K_φq₀ ² ~Wq/d, where Kφ is modulus defining FLC deformation along azimuthal angle φ; q₀ is deformation wave vector; W_q is square factor of power of FLC-to-adjoining surface adhesion.

EFFECT: reduced power consumption and higher resolution.
