Abstract: We describe a wide band variable transmission optical device having an electronically active cell comprising a guest-host mixture of a liquid crystal host and a dichroic guest dye material contained between a pair of plastic substrates. The liquid crystal host has an axis orientation that is alterable between a clear state orientation and a dark state orientation and the dichroic guest dye material includes one or more dichroic dyes. The optical device is characterized in that it exhibits a wide absorption band that is greater than 175 nm within a visible wavelength range of 400-700 nm, has a clear state transmission equal to or above 30% and a dark state transmission equal to or below 40%.

Abstract: A non-polarizer based variable light attenuating device includes a guest-host solution having a liquid crystal host and a guest dichroic dye disposed between first and second conducting layers provided on first and second transparent substrates. The guest-host solution has a low-haze while the guest dye orientation alters between a low light transmitting orientation and a high light transmitting orientation in response to a first voltage supplied to the first and second conducting layers. In response to a second voltage supplied to the first and second conducting layers, the guest-host solution changes to a focal conic light scattering orientation to achieve a high-haze translucent state.
