A multilayer light modulator includes, a light modulating stack operable to transform an electrical control signal into a modulated optical signal. The light modulating stack comprises one or more optically reflecting layers, optically transmitting layers, and optically variable layers. The optically variable layer comprises a plurality of electrophoretic particles supported in a fluid. The multilayer light modulator also includes a bias generator coupled to the optically variable layers. The bias generator is responsive to the electrical control signal, wherein the bias generator creates a bias that changes the reflectance of the light modulating stack by causing the electrophoretic particles to move within the fluid. |
