General Threshold Properties of Liquid-Crystal Slab with Weak Anchoring Boundaries
On the basis of the Rapini-Papoular anchoring energy unifying the azimuthal and polar angle anchorings, the general surface torque balance equations for field-controlled twisted chiral nematic liquid crystal cells with weak anchoring boundary coupling have been derived analytically. The relationship between the anchoring energy and the threshold field of Freedericksz, transition has been discussed rigorously.
