Claim 17:
18. A shutter system comprising:
an electronic device having a camera with a lens;
a shutter 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 comprising:
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, wherein the first pair of electrodes comprise conductive plates disposed on opposite lateral sides of the shutter body;
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.
