Abstract
An exemplary electro-wetting display (EWD) device includes an upper substrate, a lower substrate opposite to the upper substrate, a plurality of side walls interposed between the upper and lower substrates and cooperating with the upper and lower substrates to form a plurality of pixel units, a first polar liquid disposed in the pixel units, a second, colored, non-polar liquid disposed in the pixel units and being immiscible with the first liquid, and a plurality of scanning lines disposed on the lower substrate and parallel to and spaced apart from each other for providing scanning signals to the pixel units. Each of the pixel units corresponds to at least part of a corresponding previous scanning line.
