“…temperature dependence. 48 Instead the ZBD mode utilizes the flexoelectric polarization from the splay and bend deformations in the director field close to the grating surface for selection of either the homeotropic or the planar state at the grating surface. Figures 7.14a and b show the orientation of the flexoelectric polarization direction for splay and bend deformations for e 1 > 0 and e 3 < 0.…”

“…By proper design, the device can appear dark or bright when viewed between crossed polarizers with high contrast values provided by the two LC states. Moreover, the surface-induced bistability provides a series of favorable features, such as high tolerance to mechanical stress and no image sticking [22].…”

“…It has the same basic construction as the conventional twisted-nematic (TN) display used in watches. [1][2][3] Two glass, or plastic, substrates with ITO electrodes on both internal surfaces, overcoated with a polymer layer to provide alignment to the liquid crystal, are spaced about 5 µm apart. It differs in construction in only one respect: instead of the usual rubbed polymer alignment layer usually used for the TN, one of the surfaces of the ZBD has a patterned or profiled surface designed to induce two or more alignment states.…”
