摘要： An electronically dimmable optical device, including, in sequence, an active absorbing polarizer; a first static reflective polarizer; an active polarization rotator; and a second static reflective polarizer; configured so that the reflectivity and/or transmissivity of the device can be controlled (increased or decreased) by application of a voltage across the active absorbing polarizer and/or the active polarization rotator. One or more polarization levels can be selected by controlling the voltage at the active absorptive polarizer such that setting the active absorptive polarizer to a selected polarization level determines the brightness of an image produced by the device.

摘要： We describe a wide band variable transmission optical device, mixtures for use in such a device, and methods of making the same. The wide band optical device includes a 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 optical device does not use polarizers. The liquid crystal host has an axis orientation that is alterable between a clear state orientation and a dark state orientation perpendicular thereto 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 and has a clear state transmission equal to or above 30% and a dark state transmission equal to or below 40%.

摘要： A variable transmission optical device (“VTOD”) includes first and second cells in optical communication, each cell having an electro-optic material capable of changing from a state of higher light transmittance to a state of lower light transmittance upon a change of an electric field applied across the electro-optic material. The VTOD is switchable between i) a clear state having chromaticity CCS and a photopic transmission PTCS of at least 20% wherein the first cell and second cell are each in the state of higher light transmission, ii) a first darkened state having chromaticity CD1 and a photopic transmission PTD1 lower than PTCS, and iii) a second darkened state having chromaticity CD2 and a photopic transmission PTD2 that is lower than PTD1. CD1 and CD2 each fall within chroma 2 when their respective PT values correspond to a Munsell value of 5 or less.

摘要： A switchable one-way mirror device dividing first and second spaces includes a switchable electro-optic layer facing the second space and configured to be electronically switchable between a transmissive state and one or more opaque states, and a partial reflector incorporated within or adjacent the switchable electro-optic layer and facing the first space and configured to partially reflect light. The switchable one-way mirror partially transmits a first light going from the first space to the second space, and a second light going from the second space to the first space. When the switchable electro-optic layer is in an opaque state, transmission of light through the device is reduced thereby changing the ratio between the transmission of the second light to the first space and the reflection of the first light by the partial reflector resulting in reduced visibility of the second space by a viewer in the first space.

摘要： Provided is a method of producing a flexible cell unit enclosed by a border seal and filled with an electro-optic material. The flexible cell includes a first and a second substrate separated by a controlled distance maintained by spacers. The method includes providing two continuous sheets of flexible plastic material to form the first and second substrates and depositing an electro-optic material on at least one substrate. The electro-optic material is non-encapsulated, non-polymeric, and contains less than 1% polymerizable material. The method also includes pairing the first and second substrates while roll-filling the flexible cell with the electro-optic material using one or more lamination rollers so that the electro-optic material completely fills the controlled distance between the first and second substrates.

摘要： A structural interface having an adaptive liquid crystal material that is positioned to receive electromagnetic radiation and adapted to reflect a selective band of the received electromagnetic radiation so as to help with cooling of a structure in the summer and/or heating of the structure in the winter. The adaptive liquid crystal material is designed to change its selective reflection band when exposed to an activating temperature or an activating light or both. Depending on the interior and/or exterior conditions, the adaptive liquid crystal material has one or more selective reflection bands with a peak wavelength selected from the following: within a sunlight wavelength span, outside a thermal infrared wavelength span, outside the sunlight wavelength span, or within the thermal infrared wavelength span. The structural interface may be applied to an exterior or interior surface of a structural envelop or be integrated into a structural envelope material.
