Abstract
Certain electro-optic devices include liquid for changing optical properties of one or more components within such electro-optic devices. Conventional liquids used in the electro-optic devices may break down or degrade, limiting the switching speed of such electro-optic devices and causing bubbles, delamination, or other permanent defects in the electro-optic devices. The disclosed optical device includes a first set electrodes; a second set of electrodes distinct and separate from the first set of one or more electrodes; and a medium located between the first and second sets electrodes. In some cases, the medium includes ionic liquids that may increase the polarity of the medium, which increases the switching speed of the optical device. The ionic liquids have low vapor pressures, high electrochemical and thermal stabilities, and superior ionic conductivities. The ionic liquids can be nonflammable and highly viscous, which can also increase their use in portable electronic devices.
