Abstract
A colored electrophoretic display includes a transparent substrate, a transparent conductive layer, a planar electrophoretic cell, and a backplane substrate in sequence of receiving an incident light. The backplane substrate includes a first block reflective electrode, a second block reflective electrode and a third block reflective electrode, tiled in a planar arrangement perpendicular to the incident light and electrically connected to a driving circuitry in the backplane substrate. The driving circuitry electrically drives the first block reflective electrode, the second block reflective electrode and the third block reflective electrode individually as well as the transparent conductive layer to form spatially colored reflective light modulation.
