Abstract
A totally internally reflective image display having a first electrically charged particle and a second electrically charged particle of opposite charges are disclosed. By applying a non-zero voltage the particles are moved such that they frustrate total internal reflection and create a dark state. By applying a zero voltage and/or voltage pulsing, light is totally internally reflected to create a light state. The display is DC balanced and compatible with common drive electronics. Multi-colored displays may be created using first and second particles with different optical characteristics.
