Abstract
A shutter system includes an electronic device having a camera with a lens. A shutter is supported by the electronic device to block light transmission through the lens in a first state and permit light transmission in a second state. The shutter includes a shutter body containing electrically charged light blocking particles in suspension, a first pair of electrodes positioned to move the electrically charged light blocking particles to achieve the first state in response to a first voltage being applied to the first pair of electrodes, and a second pair of electrodes positioned to move the electrically charged light blocking particles to achieve the second state in response to a second voltage being applied to the second pair of electrodes.
