Abstract:
A display device comprising a pixel, where the pixel includes: (a) a polar fluid that is at least one of colored and black, (b) a non-polar fluid that is at least one of transparent and translucent, (c) a first substrate, (d) a second substrate arranged relative to the first substrate to define a channel occupied by the polar fluid and the non-polar fluid, wherein at least one of the polar fluid and the non-polar fluid is visible, (e) a reflector having a plurality of features, comprising at least one of concavities and projections, that alter an angle of reflected light from a specular reflection to provide the appearance of a diffuse reflection, the display device also including a plurality of electrodes configured to cause repositioning of the polar fluid in the channel to displace at least a first portion of the non-polar fluid and a voltage source.
