    Abstract: Methods and apparatus for an electrophoretic display in which the particle motion is a controlled, non-linear function of the applied electric field. Threshold addressing allows simple, inexpensive passive addressing techniques to be employed. The inverse electrorheological gating techniques allow the construction of a full color, passively addressed display without the need to address individual capsules. A mixture of capsules is coated randomly onto a substrate enabling the creation of inexpensive displays. All the techniques allow a significant threshold to be realized. Rapid movement of the pigment particles above the threshold allows rapid switching times for the display. Since diffusion and gravity are extremely weak forces compared to the yield stresses created, the structured or gelled medium approach provides a great improvement in the bistability of the displays.

    Abstract: Methods are provided for forming a dispersion of substantially uniform droplets. An internal phase that includes a plurality of particles suspended in a first fluid is provided and an external phase including a second fluid is provided. The internal phase is vibrated and the internal phase is applied to the external phase. Either the internal phase or a combination of the internal and external phases form a series of droplets or complex droplets of substantially uniform size.
