Abstract
A light valve unit may include a first conductive layer and a second conductive layer disposed on opposite sides of each other with respect to a plurality of cells in which at least some of the cells include a first material and a second material. The first material may have a lower light transmissivity property than the second material and a position of the first material within a corresponding cell may be changeable responsive to application of an electric field between the first and second conductive layers. The second conductive layer may include at least two electrodes and a gap defined between the two electrodes. A portion of the light valve unit adjacent to the gap may be configured to have a transmissivity that is substantially less than transmissivity of a portion of the light valve unit adjacent to cells across which the electric field is applied, but greater than or equal to transmissivity of a portion of the light valve unit adjacent to cells across which the electric field is not applied.
