A system such as a vehicle may have window that exhibit adjustable transparency. The windows may include liquid crystal devices and polymer dispersed liquid crystal devices that exhibit adjustable amounts of light transmission and haze. An optical property of a window such as window transparency may be modulated using an alternating-current modulation waveform. Modulation of the transparency of the window may be synchronized with modulated light output from a light source. The light source may be located inside the vehicle or may be located outside of the vehicle. By synchronizing the modulation of the transparency of the window with the light source output, privacy may be enhanced or glare may be reduced.

An adaptive screen including at least one liquid crystal shutter. At least one of the shutters includes at least two active zones which are addressed by a control signal which permits the switchover of the at least one corresponding shutter between a passing configuration, in which a transmittance is equal to a maximum value, and a blocking configuration, in which the transmittance is equal to a minimum value. A principal active zone covers a surface area of the adaptive screen which is equal to or lower than 60% of the surface area of the adaptive screen, in order to reduce the response time of the principal active zone.

A light control sheet including a light control layer sandwiched between first and second orientation layers and including a polymer network in which domains are dispersed and filled with a liquid crystal composition including a liquid crystal molecule and a dichroic dye, a pair of transparent electrodes sandwiching the orientation layers, and a polarizing layer positioned on an opposite side of the first orientation layer to the light control layer. The light control layer has a transmittance that increases upon application of a driving voltage to the pair of transparent electrodes. When the driving voltage is not applied between the transparent electrodes, the orientation layers orient the liquid crystal molecule and the dichroic dye horizontally to the orientation layers and orient an orient absorption ax of the dichroic dye to cross an absorption axis of the polarizing layer as viewed in a thickness direction of the light control layer.
