摘要： An electrokinetic device is configured as a dynamic lens cover and/or filter for an imaging assembly, e.g., of a mobile device, to selectively allow electromagnetic radiation to pass through a lens of the imaging assembly when the dynamic lens cover is in a first operating state or to prevent electromagnetic radiation from reaching the lens of the imaging assembly when the dynamic lens cover is in a second operating state. The electrokinetic device includes transparent first and second substrates, and a compaction trench surrounding the lens of the imaging assembly. The compaction trench stores pigment when the dynamic lens cover is in the first operating state. In the second operating state pigment is dispersed within a carrier fluid between the first and second substrates.

摘要： Embossing resins, methods of manufacturing such resins, and electrokinetic display system, which includes display cells containing such resins. The resins include a fluoropolymer in weight percentage 5%-60%, a difunctional diluent in weight percentage 0-30%, a monofunctional diluent in weight percentage 0-40%, a urethane diacrylate or functionalized nanoscale material, e.g., a functionalized urethane material, in weight percentage 5-50%, a photoinitiator in weight percentage 0.5-5%, and a surfactant in weight percentage less than 0.5%. The difunctional diluent may be Hexanediol Diacrylate, and the monofunctional diluent may be a monofunctional hydrocarbon. The resins are made by identifying a target index of refraction for a cured state thereof, and combining together, by weight percentage, the constituent components to produce the liquid state version of the embossing resin having a desired composite index of refraction.
