Abstract
A system such as a vehicle may have windows. A window may be provided with a light modular or other active layer having an electrically adjustable optical property. The active layer may have a pair of electrodes. The electrodes may be used to apply electric fields across the active layer to adjust the active layer. A lower sheet resistance electrode may be supplied with a current to ohmically heat the active layer. A higher sheet resistance electrode may be supplied with a voltage gradient to create a gradient in light transmission or other optical property as a function of distance across the higher sheet resistance electrode. The electrodes may be provided with terminals that are formed from elongated strips of metal or other terminal structures. The terminals may run along the peripheral edges of the electrodes.
