    摘要: A data exhibiting screen device comprises a layer of liquid crystals whose light scattering or transparency is controllable by applying an electric field. A ferroelectric layer of ceramic material extends face-to-face in parallel proximity to the liquid-crystal layer and constitutes a capacitance controllable by the magnitude of the applied electric field. Electric field means in the form of a cross-bar arrangement supply the field excitation.
