摘要: An eyewear system includes a variable transmission optical device and an antenna. The variable transmission optical device includes a first transparent electrode provided over a first transparent electrode area of a first substrate, a second transparent electrode provided over a second transparent electrode area of a second substrate, and an electro-optic material provided between the substrates, wherein each transparent electrode is interposed between its respective substrate and the electro-optic material. An antenna electrode is provided over an antenna area of the first substrate, wherein the antenna electrode is electrically isolated from the first transparent electrode.

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: 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: An optical device with one or more spatially variable optical response characteristics is disclosed. The optical device includes a cell including a liquid crystal material contained between a pair of substrates, each substrate having a transparent conductive layer provided thereon. An electrode connection contacts each transparent conductive layer. A driving signal source is in electrical communication with each electrode connection for application of a driving signal to the cell. An applied driving signal to the electrode connections from the driving signal source creates a voltage gradient in a gradient direction along the pair of transparent conductive layers leading away from the electrode connections. The voltage gradient is received by the liquid crystal material to produce a gradient in at least one optical response characteristic across at least a portion of the device.

摘要: Disclosed is an optical assembly having a first variable transmission layer comprising a first electro-optically active material between a first pair of substrates, a second variable transmission layer comprising a second electro-optically active material between a second pair of substrates, and an electronically switchable birefringent layer, that is capable of altering the phase of incident light, situated between the first and second variable transmission layers. The layers are arranged such that light passing through the optical assembly can be altered based on the voltage applied to each layer. The light transmission levels can be altered between maximally transmissive, minimally transmissive, and semi-transparent levels between the maximally and minimally transmissive levels.
