| abstract |
The present invention relates to electro-optical modulating display devices and, specifically, to such displays containing oil-in-oil emulsions as the imaging material. Also disclosed is a method of forming an image by movement of liquid droplets through a continuous liquid phase, the method comprising providing an array of pixel elements, each containing at least one separate reservoir of electro-optical imaging fluid comprising a colloidally stable dispersion of an oil-in-oil emulsion. |
