Abstract
A liquid crystal polymer dispersion is formed where liquid crystal encapsulation is produced by a process in which a reactive additive formulation is mixed and photo-polymerized. The polymerizable additive formulation includes monofunctional, multifunctional and photoinitiator compounds in specific composition. The polymerizable additive formulation enhances the control of deformed globule or droplet size, structure integrity, electro-optical properties, and prohibits flow of the liquid crystal as it is encapsulated. A simple process and a controllable system for encapsulating cholesteric materials that provides rugged low-power flexible passively-driven displays. Such displays offer the possibility of lower cost roll-to-roll manufacturing in addition to lighter weight, more rugged and conformable displays.
