Patent number: 11143930Abstract: A method of driving a variable transmission film is provided and a variable transmission device including the film and a controller configured to drive the film. The film may include a layer of electrophoretic material and at least one electrode, the electrophoretic material including a fluid containing a plurality of charged particles capable of moving through the fluid upon application of an electric field by the at least one electrode. The method may include applying a first voltage waveform to the film at an initial optical state and applying a second voltage waveform having a lower frequency and shorter pulse duration than the first voltage waveform to switch the film to a final optical state, wherein the film has a higher percent transmission at the initial optical state than the final optical state.Type: GrantFiled: June 20, 2019Date of Patent: October 12, 2021Assignee: E Ink CorporationInventors: Peter Carsten Bailey Widger, George G. Harris, Richard J. Paolini, Jr., Craig Alan Breen

Publication number: 20210247658Abstract: An electrophoretic medium comprises a plurality of core-shell particles and a non-polar fluid. The core-shell particles comprise an organic pigment particles core and a shell comprising a metal oxide layer and a silane layer. The metal oxide layer may have a thickness of 0.4 to 2 nm. It may be formed using a fluidized bed reactor by inserting the organic pigment into the reactor as a powder bed, contacting the powder bed with a gaseous stream comprising a metal oxide precursor and an inert gas, and contacting the powder bed with a gaseous stream of a reagent and an inert gas. The silane layer is formed from a silane compound comprising a first functional group, wherein the first functional group reacts with the metal oxide.Type: ApplicationFiled: January 25, 2021Publication date: August 12, 2021Inventors: Jay William ANSETH, Brandon MACDONALD, Craig Alan BREEN

Patent number: 11028319Abstract: A variable opacity material is provided that may be in the form of a mixture, such as an emulsion that contains a discontinuous aqueous polymeric solution having an LCST of 0 to 100° C. and a continuous phase containing a hydrophobic polymer, such as a polysiloxane. One or more salts, such as lithium bromide and sodium chloride, may be added to the aqueous solution to lower the LCST of the aqueous solution and to raise the refractive index of the aqueous polymeric solution to substantially match the refractive index of the hydrophobic polymer. The variable opacity materials may be applied in the form of a film to various substrates, such as glass.Type: GrantFiled: December 17, 2018Date of Patent: June 8, 2021Assignee: E Ink CorporationInventors: Peter Carsten Bailey Widger, Jay William Anseth, Richard J. Paolini, Jr., Craig Alan Breen, Wesley Viola
