摘要： An electrophoretic light attenuator comprises a cell including a first substrate (90), a second substrate (90) spaced apart from the first substrate, a layer arranged between the substrates and containing an electrophoretic ink (30), and a monolayer of closely packed protrusions (2) projecting into the electrophoretic ink (30) and arranged adjacent a surface of the second substrate. The protrusions (2) have surfaces defining a plurality of depressions between adjacent protrusions. The ink (30) includes charged particles (11) of at least one type, the particles being responsive to an electric field applied to the cell to move between a first extreme light state, in which the particles (11) are maximally spread within the cell so as to lie in the path of light through the cell and thus strongly attenuate light transmitted from one substrate to the opposite substrate, and a second extreme light state, in which the particles (11) are maximally concentrated within the depressions so as to let light be transmitted.

摘要： A switchable light modulator device comprises a fluid layer disposed between opposite spaced apart major surfaces of first and second substrates. Each of the substrates comprise first and second interoperable microstructures formed on the opposite major surfaces. The respective microstructures fit together to join the first and second substrates and to define wall portions for a plurality of cavities, the cavities sealing said fluid in discrete volumes.

摘要： An electrophoretic device (101) comprises a first electrode (60) and a second electrode (60) spaced apart from the first electrode (60). An electrophoretic cell (809) containing an electrophoretic ink (830) and one or more optically-transparent, non-planar, solid polymer elements (808) is located between the electrodes (60). The ink (830) includes charged particles (11) of at least one type suspended in an optically-transparent suspending fluid (820). The refractive indices of the solid polymer elements (808) and the suspending fluid (820) are matched to have a difference of less than 0.0075, and for half or more of the operating temperature range of the device (0° C.-70° C.), the thermo-optic coefficients (temperature coefficient of refractive index per Kelvin) of the solid polymer elements (808) and the suspending fluid (820) are matched to have an arithmetic-mean difference of less than 0.0002/K in magnitude.

摘要： An electrophoretic insulated glass unit (IGU) comprises an electrophoretic laminate and a pane spaced apart from the electrophoretic laminate, the respective inner faces of the laminate and the pane defining a sealed cavity there between. An outer face of the electrophoretic laminate is in contact with an environment. One inner face of the cavity has a coating that is transparent to visible light and which rejects infrared light greater than a cut-off wavelength. The electrophoretic laminate includes an electrophoretic device including charged particles of at least one type in an electrophoretic cell, the particles being responsive to an electric field applied to the electrophoretic device to move between: a first extreme light state in which particles are maximally spread within the cell to lie in the path of sunlight through the cell and to strongly absorb visible sunlight transmitted through the cell and a second extreme light state in which the particles are maximally concentrated within the cell to remove them from the path of sunlight through the cell and to substantially transmit visible sunlight through the cell. The coating is arranged to direct thermal radiation emitted by the charged particles to the environment in contact with the outer face, and the sealed cavity is arranged to direct thermal conduction diffusing from the charged particles to the environment in contact with the outer face.

摘要： A light attenuator comprises a cell comprising a first substrate and a second substrate spaced apart from the first substrate.

The ink includes charged particles of at least one type, the particles being responsive to an electric field applied to the cell to move between a first extreme light state, in which particles are maximally spread within the cell to lie in the path of light through the cell and to strongly attenuate light transmitted through the cell; over the surface of the protrusions, which deflect the particles from their path from the first substrate to the second substrate; to a second extreme light state in which the particles are maximally concentrated within the depressions to remove them from the path of light through the cell and to substantially transmit light through the cell.
