MULTI-COLOR ELECTRO-OPTICAL DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide an electro-optical display.SOLUTION: An electro-optical display includes at least two separate layers of electro-optic material, in which one of these layers can display at least one optical state that cannot be displayed by the other layer. The display is driven by a single set of electrodes between which both layers are sandwiched, the two layers being controllable at least partially independently of one another. Another form of the invention uses three different types of particles within a single electrophoretic layer, with the three types of particles being arranged to shutter independently of one another.SELECTED DRAWING: Figure 12B
