MUMBAI, India, Aug. 8 -- Intellectual Property India has published a patent application (202218050175 A) filed by E Ink Corporation, Billerica, U.S.A., on Sept. 2, 2022, for 'a process for spraying capsules on an electrophoretic medium and a process for forming an electro-optic display.'
Inventor(s) include Bull, Stephen; Brewer, Damien; Anseth, Jay William; Paolini, Richard J., Jr.; Fauvell, Thomas; Harris, George G.; and Regan, Michael Thomas.
The application for the patent was published on Aug. 8, under issue no. 32/2025.
According to the abstract released by the Intellectual Property India: "The present invention provides a process for spraying capsules of an electrophoretic medium on to a substrate, the process comprising: forming a dispersion of the capsules in a liquid; feeding the dispersion through a first orifice; and feeding a continuous stream of gas through a second, annular orifice surrounding the first orifice, thereby forming a spray of the capsules, wherein, during spraying of the capsules, a masking material covers part of the substrate, and after the spraying the masking material and the capsules thereon are removed so that, after removal of the masking material, capsules remain only on those portions of the substrate where the masking material was not present. The invention further provides a process for forming an electro-optic display, the process comprising: providing a backplane comprising at least one electrode; coating the backplane with a layer of an electro-optic material; depositing a layer of a substantially solvent- free polymerizable liquid material over the layer of electro-optic material; contacting the polymerizable liquid material with at least one light-transmissive electrically-conductive layer; and exposing the polymerizable liquid material to conditions effective to cause polymerization of the material, thereby adhering the at least one light- transmissive electrically-conductive layer to the layer of electro-optic material."
The patent application was internationally filed on Nov. 03, 2017, under International application No.PCT/US2017/059887.
