摘要： The invention relates to a liquid crystal modulator comprising at least one ferroelectric liquid crystal, and to a method for operating an optical liquid crystal modulator having at least one ferroelectric liquid crystal. The aim of the invention is to greatly diminish temperature-dependent influences during simultaneously short switching times. To this end, the invention provides that the ferroelectric liquid crystals have a DHF mode and an operating range of the electric field that exceeds 10 V/νm at the location of the liquid crystal. The operating frequency is preferably greater than 50 kHz.

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.

摘要： A main object of the present invention is to provide a process for producing a liquid crystal display having less alignment defects, which seldom causes aligning disorder at the boundary where ferroelectric liquid crystals allowed to flow are brought into contact with each other when the ferroelectric liquid crystals coated on the substrate flow. To attain the object, the present invention provides a process for producing liquid crystal display comprising a first alignment layer formation step and a liquid crystal coating step, wherein the liquid crystal coating step is a step of linearly coating the ferroelectric liquid crystals on a first alignment layer of a liquid crystal side substrate in a direction substantially perpendicular or substantially parallel to the alignment treatment direction conducted in the first alignment layer formation step.
