Abstract
An example electrophoretic display assembly includes: an outer substrate; an inner substrate; a first electrode and a second electrode disposed between the inner substrate and the outer substrate in a spaced apart relationship; and at least one substantially planar microstructure between the first and second electrodes, the microstructure containing an electrophoretic media. For example, the planar microstructures may be parallel to or perpendicular to the outer substrate. Also provided are example methods of fabricating electrophoretic display assemblies. A plurality of electrophoretic display assemblies may be combined to form an electrophoretic display, wherein each display assembly represents a pixel of the display device. The planar microstructures may increase the display quality, including the contrast or color capabilities of electrophoretic displays.
