Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A variable transmission display comprising: an electrophoretic medium comprising a fluid and a plurality of electrically charged particles dispersed in the fluid, the electrophoretic medium being capable of assuming a light-transmissive state and a substantially non-light-transmissive state; at least one light-transmissive first electrode disposed adjacent the electrophoretic medium; a plurality of light-transmissive second electrodes disposed adjacent the electrophoretic medium on the side thereof remote from the first electrode(s), the second electrodes being arranged in a plurality of rows and a plurality of columns; and voltage means for varying the potential of each of the second electrodes independently of one another, the voltage means comprising row and column electrodes connecting the second electrodes in each row and column respectively. 2. A variable transmission display according to claim 1 further comprising a transistor associated with each second electrode.
