Grayscale Color Electronic Paper

Abstract

A grayscale color electronic paper have a plurality of pixel structural units, each of them has a base color layer and a grayscale adjusting layer. The base color layer is able to display two or more colors. Colors displayed by the grayscale adjusting layer corresponds one-to-one to the colors displayed by the base color layer. The base color layer and the grayscale adjusting layer have respective driving structures. The base color layer can display colors such as black, white, red, green, blue, cyan, magenta and yellow; and the grayscale adjusting layer has multi-level grayscales, and each level of the gray scale has a steady state at a zero electric field.
