摘要： A variable light transmission device is disclosed and a method of operation of the same. The method of operation of a variable light transmission device comprises the step of (a) providing a variable light transmission device comprising a microcell layer having a plurality of microcells, each microcell comprising a protrusion structure and a channel, and including an electrophoretic medium, (b) applying a first electric field across the microcell layer to an open optical state, and (c) applying a second electric field across the microcell layer to an closed optical state, the closed optical state having lower percent light transmission than the open optical state.

摘要： A variable light transmission device is disclosed, the variable light transmission device comprising two light transmissive electrode layer and a microcell layer having a plurality of microcells. Each of the plurality of microcells includes a first type of electrically charged pigment particles and a second type of electrically charged pigment particles, a charge control agent, and a non-polar liquid. Upon application of an electric field, the amount of light passing through the device can be modulated.

摘要： A variable light transmission device is disclosed and a method of manufacture of the same. The variable light transmission device comprises two light transmissive electrodes and a microcell layer having a plurality of microcells, each microcell comprising a protrusion structure and a channel, and including an electrophoretic medium. The opacity of the device is controlled by an applied electric field.
