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.
