    摘要： An electrically controlled medium for modulating light includes two plastic thin film layers (1) and (2), and a mixture layer (3) is arranged between the two plastic thin film layers (1) and (2). The mixture layer (3) consist of smectic liquid crystals (31), polymer materials (33) and dopants (32). Electrode layers (4) are coated on one side of each of the two plastic thin film layers (1) and (2) facing to the mixture layer (3), and the electrode layers (4) are connected to a device of electrical driving system (5). The liquid crystal molecules are allowed to exhibit different molecule alignments by controlling the amplitude, frequency and driving time of the electric power applied to the electrode layers (4), so that the electrically controlled medium for modulating light can be switched between a blurred scattering state and a fully transparent state, even may be switched among a plurality of gradual translucent states of different gray levels. The medium is power saving, hard to be broken and eco friendly and it can maintain its state after power is off (memory effect). It has fast switching speed and can be broadly used for the fields of architectural decoration, privacy control areas, automotive electronics and glass, etc.
