Abstract: Provided is a liquid crystal device having one or more liquid crystal cells, each cell having an electro-chromo-dynamic (ECD) mixture interposed between two substrates covered with a conductive layer. The ECD mixture includes a liquid crystal material, dichroic dyes and an ionic material capable of inducing dynamic scattering of liquid crystal molecules. The device has a voltage supply coupled with the conductive layers for applying a voltage waveform across the liquid crystal cell, such that upon application of a first voltage waveform, the device is in a CLEAR (low-haze, low-tint) state, and upon application of a second voltage waveform, the device achieves an OPAQUE (high-haze, high-tint) state. In some cases, the device is configured so that upon application of a third voltage waveform, the device achieves a TINTED (low-haze, high-tint) state.
