The invention provides materials and methods (including driving methods) for reducing the effects of remnant voltages in electro-optic displays.

Electro-optic displays with reduced remnant voltage

Prior art processes for producing protein-based capsules (for example, capsules for use in electrophoretic media) tend to be wasteful because they produce many capsules outside the desired size range, which is typically about 20 to 50 &#x3bc;m. Capsule size distribution and yields can be improved by either (a) emulsifying a water-immiscible phase in a preformed coacervate of the protein; or (b) using a limited coalescence process with colloidal alumina as the surface-active particulate material.
