Claims36
A high contrast reflective display comprising at least one substrate, at least one electrically conductive layer and at least one electronically modulated imaging layer, wherein said electronically modulated imaging layer comprises a close-packed, ordered monolayer of domains of electrically modulated material in a fixed polymer matrix.
A method of making a high contrast reflective display comprising:
- providing a substrate;
- applying a conductive layer;
- applying at least one layer of domains of electrically modulated material in a polymer matrix;
- drying the at least one applied layer of said domains of electrically modulated material in a polymer matrix at a temperature above the chill set temperature or sol-gel transition temperature of said polymer matrix to permit self-assembly of said domains of electrically modulated material into a close-packed monolayer of said domains of electrically modulated material;
- and fixing said polymer matrix to preserve said close-packed monolayer of domains of electrically modulated material.
