This paper discusses the dynamics of the optical response of a nematic liquid crystal with positive dielectric anisotropy for splay deformation of the layer and how it is affected by the shape of the electric-field oscillations. The efficiency of the action of sinusoidal, bipolar, and unipolar meanders with different frequencies and polarities is compared. It is shown that using a unipolar meander promotes a substantial acceleration of the liquid crystal’s optical response when the electrical signal is simultaneously reduced.
