Bistable display panel with a layer of uniformly sized domains of light modulating material

摘要

A light-modulating, electrically responsive sheet (10) including a substrate (15) and electrically conductive layer (20) formed over the substrate (15). The sheet further includes a light-modulating layer (30) disposed over the electrically conductive layer (20) and including at least one dispersible light-modulating material and coalescence limiting material into which the dispersible light-modulating material(s) is provided so that such dispersible light-modulating material coalesces to form a limited coalesced material having a set of domains (32,34) each having a set of domains that exhibit different electrically responsive optical states.
