Abstract
A variable transmission display comprises an electrophoretic medium having electrically charged particles dispersed in a fluid, the electrophoretic medium being capable of assuming a light-transmissive state and a substantially non-light-transmissive state; a light-transmissive first electrode disposed adjacent one side of the electrophoretic medium; light-transmissive second electrodes disposed adjacent the other side of the electrophoretic medium; and voltage means for varying the potential each of the second electrodes independently of one another.
