Abstract
Electrowetting devices (EWD) are presented. The electrowetting device includes a first substrate and an opposing second substrate with a polar fluid layer and a non-polar fluid layer interposed therebetween. A first transparent electrode is disposed on the first substrate. A second electrode is disposed on the second substrate. A first partition structure is disposed on the first substrate; thereby defining a plurality of color sub-pixels. A dye and/or a pigment substance is doped in one of the polar fluid layer and the non-polar fluid layer. A luminescence substance is doped in one of the polar fluid layer and the non-polar fluid layer. An emission module (also known as an excitation module) is disposed underlying the bottom of the first substrate. The colors of the non-polar fluid layer in the neighboring sub-pixels are different.
