Abstract
An electro-optical system includes a voltage supply device, an active polarizing layer, a retarding layer, and a reflective layer. The active polarizing layer is electrically coupled to the voltage supply device. The active polarizing layer is configured to switch back and forth between a non-polarized state and a polarized state as the voltage supply device supplies varying levels of voltage. The retarding layer is configured to alter the polarization state of light traveling through it. The reflective layer is positioned adjacent to the retarding layer.
